Abstract

Depression in young women during their early twenties represents a critical public health concern, with this demographic showing elevated rates of depressive symptoms and major depressive disorder (MDD) onset. This analytical review examines the multifaceted etiologies of depression in women aged 20-25, synthesizing evidence from contemporary research to identify and analyze key risk factors across biological, psychological, social, and environmental domains. Women are about twice as likely as are men to develop depression during their lifetime [1] [2], with the gender gap becoming particularly pronounced during the transition to adulthood.

Depression rates in young people have risen sharply in the past decade, especially in females [3], highlighting the urgency of understanding the complex interplay of factors that contribute to depression onset during this vulnerable developmental period. This paper examines eight primary etiological domains: hormonal and reproductive factors, academic and transitional stress, social media and digital influences, relationship dynamics and romantic experiences, body image and eating-related concerns, sleep disturbances and lifestyle factors, childhood trauma and adverse experiences, and genetic predisposition.

The analysis reveals that depression in young women emerges from a complex interaction of multiple risk factors rather than single causative elements. Depression is explained by multiple different risk factors that have probabilistic risk effects; no single risk factor is necessary or sufficient to explain the causes of depression [4]. Key findings indicate that the early twenties represent a particularly vulnerable period due to the convergence of biological maturation, social role transitions, and environmental stressors. The review concludes with recommendations for integrated prevention and intervention approaches that address the multifactorial nature of depression in this population.

Introduction

Depression represents one of the most significant mental health challenges facing young women in their early twenties, a developmental period characterized by profound biological, psychological, and social transitions. Depression is one of the leading causes of disease-related disability in women, and they are nearly twice as likely as men to suffer from an episode of depression [5]. This gender disparity becomes particularly pronounced during the transition from adolescence to early adulthood, making women in their early twenties a population of special concern for mental health professionals and researchers.

The early twenties represent a unique developmental window where multiple risk factors converge to create heightened vulnerability for depression onset. The difference begins in early life and persists through to mid-life, and as such, these reproductive years have been labelled by some as a ‘window of vulnerability’ [6]. During this period, young women navigate complex challenges including academic pressures, career decisions, relationship formation, identity development, and increasing independence from family support systems.

Contemporary research has documented alarming trends in depression prevalence among young adults. Depression rates in young people have risen sharply in the past decade, especially in females, which is of concern because adolescence is a period of rapid social, emotional, and cognitive development and key life transitions [7] [8]. This increase has coincided with significant sociocultural changes including the proliferation of social media, changing economic conditions, evolving gender roles, and increased academic and career pressures.

Understanding the etiologies of depression in young women requires a multidimensional approach that considers the complex interplay between biological, psychological, social, and environmental factors. Gender-related subtypes of depression are suggested to exist, of which the developmental subtype has the strongest potential to contribute to the gender gap [9]. This developmental subtype encompasses the unique constellation of factors that emerge during the transition to adulthood, making it particularly relevant for understanding depression in women during their early twenties.

The significance of this developmental period extends beyond immediate mental health concerns. Depression in adolescence and early adulthood is associated with recurrence in later life. Approximately 50% of adolescents will have another episode of depression, with a nearly 3-times higher risk of depression in adulthood compared with those who did not have depression in adolescence [10]. This pattern emphasizes the critical importance of understanding and addressing depression during the early twenties to prevent long-term mental health consequences.

This analysis aims to examine the multifaceted etiologies of depression in women aged 20-25 through an integrated lens that considers the complex interactions between various risk factors. By synthesizing current research evidence, this review seeks to provide a nuanced understanding of how different etiological factors contribute to depression vulnerability during this critical developmental period, ultimately informing more effective prevention and intervention strategies.

Literature Review and Theoretical Framework

Historical Context and Gender Differences in Depression

The recognition of gender differences in depression has been a consistent finding across decades of research. A 2003 review listed evidence from studies up to the early 2000s yielding sex ratios of about 2·1 for lifetime and 1·7 for point prevalence (women:men) of major depressive disorder and dysthymia in adults, and similar ratios for studies in adolescents [11]. This pattern has remained remarkably stable across different cultural contexts and continues to be observed in contemporary research.

The emergence of gender differences in depression typically occurs during puberty, with rates becoming equal between boys and girls before this developmental period. Given that depression often begins early in life and that the gender difference emerges with puberty, the focus of prevention has so far been on children and adolescents. Although the gender difference first emerges in puberty, other experiences related to changes in sex hormones (pregnancy, menopause, use of oral contraceptives, and use of hormone replacement therapy) do not significantly influence major depression [12] [13].

This pattern suggests that the key to understanding elevated depression rates in young women lies in examining the complex interplay between biological vulnerabilities and environmental factors that emerge during the transition to adulthood. These observations suggest that the key to understanding the higher rates of depression among women than men lies in an investigation of the joint effects of biological vulnerabilities and environmental provoking experiences. Advancing understanding of female depression will require future epidemiologic research to focus on first onsets and to follow incident cohorts of young people through the pubertal transition into young adulthood [14].

Theoretical Models of Depression Development

Contemporary understanding of depression etiology has moved beyond single-factor explanations toward more complete, multifactorial models. Depression is explained by multiple different risk factors that have probabilistic risk effects; no single risk factor is necessary or sufficient to explain the causes of depression. Recognising common risk factors and clinical antecedents of depression can be helpful in guiding prevention and surveillance efforts [15].

The developmental psychopathology framework provides a particularly relevant lens for understanding depression in young women during their early twenties. This model emphasizes how various risk and protective factors interact across development to influence mental health outcomes. The assessment of possible factors contributing to the gender gap in depression suggests several gender-related depressive subtypes, which might deserve specific assessment in future research. These subtypes of depression—early onset, developmental, reproductive, and pathophysiological—are not exhaustive and might overlap in risk factors and clinical phenotypes [16].

The stress-diathesis model also provides important insights into depression development during early adulthood. This model suggests that individuals with certain vulnerabilities (diatheses) are more likely to develop depression when exposed to environmental stressors. For young women, these vulnerabilities may include hormonal sensitivity, genetic predisposition, cognitive patterns, and social factors, while stressors may include academic pressure, relationship challenges, role transitions, and societal expectations.

 

 

The Significance of Early Adulthood as a Risk Period

The early twenties represent a particularly vulnerable period for depression onset due to the convergence of multiple developmental challenges. The transition to college presents a period of vulnerability to mental illness, and opportunity for positive psychosocial development. The present study sought to build an explanatory person-centered and contextualized model of student wellbeing in the transition to college [17].

This developmental period is characterized by what researchers term “emerging adulthood,” a time of increased exploration, instability, and identity formation. Emerging adulthood: A theory of development from the late teens through the twenties. American psychologist, 55(5), 469 [18]. During this period, young women face multiple challenges simultaneously, including academic pressures, career decisions, relationship formation, financial independence, and identity consolidation.

The cumulative nature of stressors during this period can overwhelm coping resources and trigger depression in vulnerable individuals. Finally, people most likely to experience chronic stressors over the school year included women, people who identify as sexual minorities and first-generation students [19]. This finding highlights how certain demographic characteristics can compound vulnerability during this critical developmental period.

  

Methodology

This analytical review employed an extensive literature synthesis approach to examine the etiologies of depression in women during their early twenties. The methodology focused on integrating contemporary research findings across multiple domains to provide a nuanced understanding of the complex factors contributing to depression risk in this population.

Literature Search and Selection

The analysis drew upon peer-reviewed research published between 2010 and 2024, with particular emphasis on studies published within the last five years to capture current trends and understanding. Sources included major psychological, psychiatric, and medical databases, focusing on empirical studies, systematic reviews, and meta-analyses that examined depression risk factors in young women.

Key search terms included combinations of: depression, major depressive disorder, young women, early adulthood, college students, emerging adults, risk factors, etiology, gender differences, and developmental psychopathology. The search prioritized studies that specifically examined women in the 18-25 age range or provided gender-specific analyses within broader age ranges.

Inclusion Criteria

Studies were included if they: (1) examined depression risk factors, prevalence, or etiology in young women aged 18-25; (2) provided gender-specific analyses or focused specifically on female populations; (3) utilized validated measures of depression or depressive symptoms; (4) employed longitudinal, cross-sectional, or meta-analytic designs; and (5) were published in peer-reviewed journals in English.

Analytical Framework

The analysis organized risk factors into eight primary etiological domains based on contemporary theoretical models and empirical evidence:

1. Hormonal and Reproductive Factors: Including menstrual cycle influences, hormonal fluctuations, and reproductive health considerations

2. Academic and Transitional Stress: Encompassing college-related pressures, career decisions, and role transitions

3. Social Media and Digital Influences: Examining the impact of digital technology and social media use on mental health

4. Relationship Dynamics and Romantic Experiences: Including romantic relationships, breakups, and interpersonal stressors

5. Body Image and Eating-Related Concerns: Covering body dissatisfaction, eating disorders, and appearance-related pressures

6. Sleep Disturbances and Lifestyle Factors: Examining sleep quality, lifestyle choices, and health behaviors

7. Childhood Trauma and Adverse Experiences: Including early life adversity and its long-term effects

8. Genetic Predisposition: Covering heritability, genetic risk factors, and gene-environment interactions

Data Synthesis Approach

The synthesis employed a narrative analytical approach that examined evidence quality, identified patterns across studies, and highlighted areas of convergence and divergence in the literature. The analysis considered study methodology, sample characteristics, measurement approaches, and effect sizes when available. Particular attention was paid to longitudinal studies that could establish temporal relationships between risk factors and depression onset.

Limitations

This review acknowledges several methodological limitations. First, the focus on published literature may introduce publication bias toward significant findings. Second, the heterogeneity in depression measures, study populations, and methodological approaches across studies limits direct comparisons. Third, the rapidly evolving nature of some risk factors (particularly technology-related factors) means that older studies may not reflect current experiences. Finally, the complex interplay between risk factors makes it challenging to isolate individual contributions to depression risk.

Analysis of Etiological Factors

1. Hormonal and Reproductive Factors

The role of hormonal fluctuations in depression vulnerability represents one of the most biologically grounded explanations for elevated depression rates in young women. Research has consistently identified the menstrual cycle as a significant factor influencing mood regulation and depression risk during reproductive years.

Menstrual Cycle and Mood Regulation

PMDD is a prevalent disorder that affects women across the world. People with PMDD should be monitored for future development of depression and vice versa [20]. Premenstrual dysphoric disorder (PMDD) represents the most severe form of menstrual-related mood disturbance, affecting approximately 3-8% of reproductive-age women. However, even subclinical menstrual-related mood changes can contribute to depression vulnerability in young women.

The relationship between menstrual symptoms and depression appears to be bidirectional and cumulative. Girls with higher depressive symptoms and higher somatic complaints are at greater risk for experiencing menstrual symptoms and increasing symptoms across adolescence, with a heightened vulnerability for girls with lower baseline menstrual symptoms [21]. This suggests that depression and menstrual symptoms may reinforce each other over time, creating a cycle of increasing vulnerability.

Hormonal Sensitivity and Depression Risk

Research indicates that some women may have heightened sensitivity to hormonal fluctuations, making them more vulnerable to mood disturbances during reproductive transitions. It has been hypothesized that women presenting with episodes of depression associated with reproductive events (i.e., premenstrual, postpartum, menopausal transition) may be particularly prone to experiencing depression, in part because of a heightened sensitivity to intense hormonal fluctuations [22] [23].

The hypothalamic-pituitary-gonadal axis plays a crucial role in this sensitivity. Hormones and neurotransmitters share common pathways and receptor sites in areas of the brain linked to mood, particularly through the hypothalamic-pituitary-gonadal axis [24]. This biological connection provides a mechanistic explanation for how hormonal changes can directly influence mood regulation and depression risk.

Diurnal Hormonal Rhythms in Depression

Advanced research has revealed complex patterns in how hormonal rhythms differ between women with and without depression. The diurnal estradiol rhythm was quite consistent among different menstrual phases within both groups, while the depressed patients had overall larger amplitudes than controls, which is negatively correlated with disease duration. Significant positive correlations between the two hormone rhythms were found for 24-h mean level, peak, and trough in late luteal phase [25].

These findings suggest that depression is associated with altered hormonal regulation patterns rather than simply abnormal hormone levels. The relationship between hormonal fluctuations and depression appears to involve complex interactions between multiple hormonal systems, including both reproductive hormones and stress hormones like cortisol.

Clinical Implications of Hormonal Factors

The evidence for hormonal influences on depression has important clinical implications for young women. The prevalence of menstrual disorders was significantly higher in the antidepressant group (24.6%) than the control group (12.2%). The incidence of antidepressant-induced menstruation disorder was 14.5% [26]. This bidirectional relationship between depression treatment and menstrual function highlights the need for integrated approaches to women’s mental and reproductive health.

Understanding hormonal factors can also inform prevention strategies. Young women experiencing significant menstrual-related mood symptoms may benefit from early intervention to prevent progression to major depression. Additionally, awareness of hormonal influences can help both patients and providers better understand mood fluctuations and develop appropriate coping strategies.

2. Academic and Transitional Stress

The transition to college and early career represents one of the most significant stressors facing young women in their early twenties. This period involves multiple simultaneous challenges that can overwhelm coping resources and trigger depression in vulnerable individuals.

College Transition and Academic Pressure

Consistent with prior research, students—on average—experienced moderate increases in depression and anxiety from the summer before college through the spring quarter, with wide variability across students and no clear patterning by demographic groups [27] [28]. This pattern demonstrates that the college transition period represents a vulnerable time for mental health, with depression and anxiety symptoms typically increasing during the initial adjustment period.

The academic environment creates multiple stressors that can contribute to depression development. The results indicated that the top three concerns were academic performance, pressure to succeed, and post-graduation plans. Demographically, the most stressed, anxious, and depressed students were transfers, upperclassmen, and those living off-campus [29]. These findings highlight how academic pressures extend beyond coursework to encompass broader concerns about future success and life direction.

Mediation Pathways: Academic Stress to Depression

Research has identified specific pathways through which academic stress contributes to depression development. Academic stress could affect depression through the chain mediation role of negative affect and sleep quality. Results indicated that academic stress could not only directly affect depression, but also affect depression through the mediation role of negative affect and sleep quality. The chain mediating effects includes three paths, namely, the mediating role of negative affect, the mediating role of sleep quality, and the chain mediating role of negative affect and sleep quality [30] [31].

This research reveals that academic stress doesn’t operate in isolation but rather triggers a cascade of psychological and physiological responses that ultimately contribute to depression. The identification of negative affect and sleep quality as mediating factors provides important targets for intervention.

Gender Differences in Academic Stress Response

Young women may be particularly vulnerable to certain types of academic stressors. Anxiety turned out to be the most prevalent and serious issue for college students, especially for female students. Female students scored significantly higher in anxiety than males in the first and second years. Female freshmen’s anxiety levels were also associated with their body image, drinking habits, and academic performance [32] [33] [34].

The intersection of academic stress with other concerns like body image suggests that young women experience a more complex constellation of stressors during college years. This multifaceted stress experience may partially explain why women show higher rates of depression during this developmental period.

Chronic Stress and Vulnerability

The persistence of academic stress over time appears to be particularly problematic for mental health outcomes. Third, chronic stressors were strongly predictive of more negative outcomes, and self-compassion and coping skills did not buffer their effects. Finally, people most likely to experience chronic stressors over the school year included women, people who identify as sexual minorities and first-generation students [35].

This finding suggests that young women, particularly those from marginalized backgrounds, may face sustained stress that overwhelms their coping resources. The inability of typical coping strategies to buffer against chronic stress highlights the need for more thorough support systems and stress management approaches.

Financial and Career-Related Stress

Beyond immediate academic concerns, young women in their early twenties face significant stress related to financial pressures and career uncertainty. Students who grew up in families lacking financial stability are more likely to show symptoms of depression and anxiety, indicating that financial difficulties correlate with higher rates of these mental health problems [36].

The combination of student debt, competitive job markets, and uncertain economic conditions creates additional layers of stress that can contribute to depression development. For many young women, these pressures are compounded by concerns about work-life balance, career advancement, and societal expectations about success and achievement.

3. Social Media and Digital Influences

The proliferation of social media and digital technology has created unprecedented influences on young women’s mental health. Contemporary research has identified significant associations between social media use patterns and depression risk, with young women being particularly vulnerable to negative effects.

Social Media Use and Depression Associations

Large-scale research has consistently documented associations between social media use and depression in young adults. SM use was significantly associated with increased depression. This study assessed the association between SM use and depression in a nationally representative sample of young adults. Compared to those in the lowest quartile of total time per day spent on SM, participants in the highest quartile had significantly increased odds of depression after controlling for all covariates [37] [38] [39].

The relationship appears to be dose-dependent, with greater social media use associated with higher depression risk. Compared to those who used 0–2 social media platforms, participants who used 7–11 social media platforms had substantially higher odds of having increased levels of both depression and anxiety symptoms [40]. This suggests that both time spent and platform diversity contribute to mental health risk.

Mechanisms of Social Media-Related Depression

Research has identified specific mechanisms through which social media use may contribute to depression in young women. Our results show that the frequency of passive social media use is positively related to the level of psychological anxiety. Social comparison, social influence, and unclear self-concepts under social media use are negatively predictive of psychological anxiety [41].

Passive social media use, characterized by scrolling and consuming content without active engagement, appears particularly problematic. This type of use can facilitate negative social comparisons and reinforce feelings of inadequacy, particularly among young women who are already navigating identity formation and social pressures.

Body Image and Social Media

Social media’s impact on body image represents a particularly significant pathway to depression for young women. Concern has risen that increased SNS use may be influencing mental health, contributing to body image concerns, eating disorders, and psychological distress. Some experimental and correlational studies have demonstrated that viewing fitspiration content negatively effects body image and eating disorder behaviors. Exposure to fitspiration undoubtedly influences self-interpretation and can therefore influence eating disorder behaviors [42] [43] [44].

The emergence of “fitspiration” and other wellness-related content has created new forms of appearance-related pressure that may be particularly harmful to young women’s mental health. These platforms often promote unrealistic body ideals while disguising appearance pressure as health promotion.

Problematic Social Media Use Patterns

Research distinguishes between general social media use and problematic use patterns that are more strongly associated with mental health problems. Meta-analyses found small but significant positive associations between social media use, depression, and anxiety. In addition, problematic social media use was positively associated with depression, anxiety, and sleep problems, and negatively associated with wellbeing [45] [46].

Problematic social media use involves compulsive checking, difficulty controlling use, and using social media to escape negative emotions. Results showed that there was a significant positive correlation between PSMU with anxiety and depression severity. Salience was the core symptom in the PSMU symptoms network. Enthusiasm was the core symptom in the symptomatic comorbidity network of PSMU, anxiety and depression [47] [48].

Longitudinal Evidence and Causality

While much research on social media and depression is cross-sectional, emerging longitudinal evidence provides insights into causal directions. Baseline SMU was associated with later depression, but not vice versa [49]. This suggests that social media use may contribute to depression development rather than simply reflecting existing depression.

However, the relationship appears complex, with some studies finding bidirectional associations or no significant longitudinal effects. Within-person changes in self- and other oriented social media behavior were unrelated to within-person changes in symptoms of depression or anxiety two years later, and vice versa. The frequency of posting, liking, and commenting is unrelated to future symptoms of depression and anxiety [50] [51].

Protective Factors and Positive Use

Not all social media use is associated with negative mental health outcomes. Research has identified patterns of use that may be neutral or even beneficial. Engagement via platforms such as Facebook, Twitter, Reddit, Instagram, Snapchat, and Tumblr may provide opportunities for keeping in touch with family and friends as well as other social interactions that may increase social capital and alleviate depression and anxiety. Similarly, use of social media may facilitate forming connections among people with potentially stigmatizing health conditions, including depression and anxiety [52].

The key appears to be the quality and nature of social media engagement rather than use per se. Active, meaningful social interactions through digital platforms may provide social support and connection, while passive consumption and social comparison behaviors appear more likely to contribute to depression risk.

4. Relationship Dynamics and Romantic Experiences

Romantic relationships and their dissolution represent significant sources of both stress and support for young women in their early twenties. The intensity of romantic experiences during this developmental period, combined with limited relationship experience and ongoing identity formation, creates unique vulnerabilities for depression development.

Romantic Breakups and Depression Risk

Research has consistently identified romantic breakups as significant triggers for depression, particularly in young adults. Results indicated a heightened likelihood of 1st onset of MDD during adolescence if a recent break-up had been reported; in contrast, a recent break-up did not predict recurrence of depression. Additional analyses to determine the discriminant validity and specificity of these findings strongly supported the recent break-up as a significant risk factor for a 1st episode of MDD during adolescence [53] [54] [55].

The vulnerability to depression following breakups appears particularly pronounced for first episodes, suggesting that the initial experience of romantic loss may be especially challenging for young people still developing coping strategies and emotional regulation skills. Even though our sample of individuals who recently have experienced a relationship breakup can be on average considered non-depressed, group-level depression scores were elevated compared to individuals in a relationship and 26.8% reported symptoms corresponding to mild, moderate or severe depression [56].

Recovery Trajectories and Individual Differences

While breakups represent significant stressors, research has also identified factors that influence recovery and resilience. In our sample of participants reporting a single breakup during the 2-year study period, breakup was associated with a temporary increase in depressive symptoms that returned to pre-breakup levels within three months. A general low sense of control was associated with higher depressive symptoms at all time points. Our results suggest that a natural course of response to young adult breakups is characterized by recovery within three months and that subjective appraisal and sense of control contribute to this adaptive response [57] [58].

The subjective meaning attributed to the breakup appears crucial for determining mental health outcomes. We observed increased symptoms among negatively appraised, but not positive or neutral, events [59]. This finding highlights the importance of cognitive factors in determining how relationship events affect mental health.

Attachment and Coping Strategies

Individual differences in attachment style and coping strategies significantly influence vulnerability to depression following relationship stressors. Breakups are common among emerging adults and are associated with elevated depressive and anxiety symptoms, especially in the presence of attachment insecurities. Results from a longitudinal autoregressive cross-lagged model showed that pre-breakup attachment insecurities were related to higher depressive and anxiety post-breakup symptoms through higher use of self-punishment and lower use of accommodation coping strategies. Findings highlight coping strategies as potential intervention targets to promote the recovery of emerging adults experiencing breakup distress [60] [61].

The identification of specific coping strategies as mediating factors provides important targets for intervention. Self-punishment and avoidance strategies appear particularly problematic, while accommodation and adaptive coping strategies may promote resilience.

Intimate Partner Violence and Mental Health

For some young women, romantic relationships involve experiences of intimate partner violence (IPV), which significantly increase depression risk. Results show temporal changes in depressive symptoms, such that increases in depressive symptoms correspond to IPV exposure. While prior work has theorized that certain populations may be at increased psychological vulnerability from IPV, results indicate that both perpetration and victimization are associated with increases in depressive symptoms for both men and women, and irrespective of whether IPV exposure occurred in adolescence or young adulthood [62].

The impact of IPV on mental health appears to be consistent across different demographic groups and relationship types. In multivariate models, victimization was a risk factor for depression with the inclusion of prior depression, family factors reflecting the intergenerational transmission of violence, sociodemographic background, and relationship characteristics including union status. Arguing and poor communication influenced victimization and depression [63] [64].

Relationship Quality and Depression

Beyond dramatic events like breakups or violence, ongoing relationship quality significantly influences mental health. Higher levels of women’s positive engagement predicted lower symptom levels for both partners, and higher women’s withdrawal predicted higher own symptom levels. Relative increases in couples’ psychological aggression and decreases in positive engagement were additionally associated with increases in women’s symptoms over time [65].

These findings suggest that women may be particularly sensitive to relationship dynamics and their mental health may be more closely tied to relationship quality than men’s. The bidirectional nature of this relationship means that relationship problems can both contribute to and result from depression symptoms.

Social Support and Relationship Context

The broader social context of romantic relationships also influences their impact on mental health. Young women who have strong social support networks appear more resilient to relationship stressors. Both types of marital disruption were strongly linked to loneliness, from where different relations emerged to other depressive symptoms. Amongst others, loneliness had a stronger connection to perceiving oneself as a failure in separated compared to widowed individuals [66].

The role of loneliness as a mediating factor highlights the importance of maintaining social connections beyond romantic relationships. Young women who rely heavily on romantic partners for social support may be particularly vulnerable to depression when relationships end or become problematic.

5. Body Image and Eating-Related Concerns

Body image concerns and eating-related issues represent significant risk factors for depression in young women, reflecting the intersection of biological, psychological, and sociocultural influences during early adulthood. This period is characterized by ongoing identity formation, increased social comparison, and exposure to cultural pressures regarding appearance and weight.

Body Dissatisfaction as a Depression Predictor

Longitudinal research has established body dissatisfaction as a significant predictor of depression onset in young women. Elevated body dissatisfaction, dietary restraint, and bulimic symptoms at study entry predicted onset of subsequent depression among initially nondepressed youth in bivariate analyses controlling for initial depressive symptoms. Results were consistent with the assertion that the body-image- and eating-related risk factors that emerge after puberty might contribute to the elevated rates of depression for adolescent girls [67] [68].

This relationship appears to be particularly relevant during the transition from adolescence to adulthood, when body image concerns often intensify. Dissatisfaction with one’s figure seems to be consistently related to worsening eating pathology. Hierarchical regressions controlling for Time 1 levels of eating disorder symptoms revealed that changes in Bulimia were related to the psychological measures and to Figure Dissatisfaction [69] [70].

Mediating Mechanisms: Self-Esteem and Depression

Research has identified specific psychological mechanisms through which body image concerns contribute to depression. The purpose of this study was to investigate the hypothesis that the effect of body dissatisfaction on disordered eating behavior is mediated through self-esteem and depression. The results showed that the effect of body dissatisfaction on disorder eating was completely mediated, whereas the effect of body image importance was partly mediated. Both self-esteem and depression were significant mediators. Depression had a direct effect on binge eating. This effect was significantly stronger among women [71] [72] [73].

The identification of self-esteem and depression as mediating factors suggests that body dissatisfaction contributes to depression through its impact on self-concept and emotional regulation. For young women, appearance concerns may become central to identity and self-worth, making them particularly vulnerable to depression when body image is negative.

Eating Disorders and Depression Comorbidity

The relationship between eating disorders and depression is complex and bidirectional. Body image and depression contribute to eating disorders and treating depression could reduce susceptibility to eating disorders. The results showed that 65.5% of the students were depressed and 6.3% were susceptible to eating disorders. There was a significant positive relationship between depression and eating disorders and a negative relationship between body image and depression as well as between body image and eating disorders [74] [75] [76].

These high rates of comorbidity suggest that body image concerns, eating disorders, and depression form a cluster of related problems that often co-occur in young women. These findings extend current understanding of the relationships between binge eating, body image, depression, and self-efficacy. The significance of body image, especially in relation to negative social consciousness, was determined when comparing several psychological and behavioral factors thought to influence binge eating [77].

Social and Cultural Influences

Contemporary research has highlighted how social media and cultural influences exacerbate body image concerns and their relationship to depression. In more recent years researchers have observed a shift away from the thin ideal, and towards the athletic ideal as a “healthier” alternative. “Fitspiration” highlights a toned, muscular figure through healthy eating and exercise. Unlike thinspiration, which is primarily targeted towards women, fitspiration also targets men through its emphasis on muscularity. Some experimental and correlational studies have demonstrated that viewing fitspiration content negatively effects body image and eating disorder behaviors [78] [79] [80].

The evolution of appearance ideals from thinness to athletic fitness has created new forms of pressure that may be particularly problematic for young women. These “wellness” focused ideals can disguise appearance pressure as health promotion, making them more difficult to recognize and resist.

Treatment Implications

Understanding the mediating role of body image in depression has important treatment implications. If the effect of body dissatisfaction on disordered eating can be explained by self-esteem and depression, treatment may benefit from focusing more on self-esteem and depression than body dissatisfaction. Existing treatment focuses on eating behavior first and mechanisms such as self-esteem and depression second. The results from this study suggest that an earlier focus on self-esteem and depression may be warranted in the treatment of disordered eating [81] [82] [83].

This research suggests that interventions targeting body image concerns in young women should address underlying self-esteem and mood issues rather than focusing solely on appearance-related cognitions. Such approaches may be more effective at preventing both eating disorders and depression.

Protective Factors and Resilience

While much research focuses on risk factors, emerging evidence has identified protective factors that may buffer against body image-related depression. These include body acceptance, self-compassion, and diverse sources of self-worth beyond appearance. Eating concerns and depressive affect emerged as significant independent predictors of body image for both ethnic groups [84] [85], suggesting that interventions addressing eating concerns and mood may simultaneously improve body image outcomes.

6. Sleep Disturbances and Lifestyle Factors

Sleep quality and patterns represent fundamental biological factors that significantly influence depression risk in young women. The early twenties are characterized by significant sleep pattern changes, academic and social pressures that disrupt sleep, and lifestyle factors that can compound sleep problems and their impact on mental health.

Sleep Debt and Depression Risk

Research has consistently documented strong associations between sleep problems and depression in young women. Diminished sleep apparently risked depressive symptoms among the female undergraduate students studied. Both studies showed that about 20% of students reported weekday sleep debts of greater than 2 h and about 28% reported significantly greater sleep debt and had significantly higher depression scores than other students. Diminished sleep apparently risked depressive symptoms among the female undergraduate students studied. This yields a practical message that late bedtimes risk depressive symptoms [86] [87] [88] [89].

The concept of “sleep debt” – the cumulative effect of insufficient sleep over time – appears particularly relevant for understanding depression risk in young women. Both studies showed that about 20% of students reported weekday sleep debts of greater than 2 h and about 28% reported significantly greater sleep debt and had significantly higher depression scores than other students. Among female college students, those who report a sleep debt of at least 2 h or significant daytime sleepiness have a higher risk of reporting melancholic symptoms than others [90] [91].

Bidirectional Relationships: Sleep and Mental Health

Contemporary research has revealed bidirectional relationships between sleep quality and depression, suggesting that sleep problems both contribute to and result from depression. Either at baseline or during follow-up, the PSQI global score was positively associated with scores for depression, anxiety, and stress. More importantly, the cross-lagged analysis showed that PSQI global score at baseline was positively related to depression, anxiety, and stress scores a year later and depression, stress and anxiety scores at baseline were related to PSQI global score a year later. More importantly, a bidirectional relationship between PSQI global score and depression, anxiety, and stress scores was detected [92] [93] [94].

This bidirectional relationship suggests that sleep problems and depression may reinforce each other over time, creating a cycle that becomes increasingly difficult to break without intervention.

Mediating Pathways: Sleep, Stress, and Depression

Research has identified specific pathways through which sleep problems contribute to depression development. Academic stress could affect depression through the chain mediation role of negative affect and sleep quality. Results indicated that academic stress could not only directly affect depression, but also affect depression through the mediation role of negative affect and sleep quality. The chain mediating effects includes three paths, namely, the mediating role of negative affect, the mediating role of sleep quality, and the chain mediating role of negative affect and sleep quality [95] [96].

These findings reveal that sleep quality serves as both a direct pathway to depression and an indirect pathway through which other stressors (like academic pressure) contribute to depression risk. The mediation through negative affect suggests that sleep problems may compromise emotional regulation, making individuals more vulnerable to depression.

Gender Differences in Sleep and Mental Health

Young women appear to be particularly vulnerable to sleep-related mental health problems. High stress levels are associated with sleep disturbances, less nocturnal total sleep time, higher fatigue severity, and more depressive symptoms. Perceived stress and sleep disturbances are significant predictors for depressive symptoms and physical symptoms [97].

Several studies reported that females tend to report more sleep problems and more emotional distress. Chow et al. found that females reported higher co-rumination and depressive symptoms, both of which were related to more sleep problems [98] [99] [100] [101]. This gender difference may reflect biological factors, social pressures, or differences in stress exposure and coping strategies.

Sleep Quality Components and Depression

Research examining specific components of sleep quality has revealed which aspects are most strongly related to depression risk. PSQI components with showed most disturbances included subjective sleep quality, sleep latency, sleep duration, sleep disturbance and daytime dysfunction. Findings showed that 38.9% of the participants were depressed, 56.7% of students had severe stress, and 33.1% had mild to moderate and severe levels of anxiety [102] [103].

The high prevalence of sleep problems among college students, combined with elevated rates of depression and anxiety, highlights the importance of addressing sleep as a component of mental health promotion and intervention.

Social Support as a Moderating Factor

Research has identified social support as an important moderating factor in the relationship between sleep problems and mental health. Social support moderated the adverse influence of negative affect on sleep quality. Social support decreases the impact of negative affect on sleep quality. Specifically, the association between negative affect and sleep quality was stronger for college students with low social support than those with high social support [104].

This finding suggests that strong social connections may buffer against the negative effects of stress on sleep, potentially breaking the cycle between stress, sleep problems, and depression.

Lifestyle Factors and Sleep Hygiene

The college environment often promotes lifestyle factors that can negatively impact sleep quality and, consequently, mental health. Physical activity and healthy social relations improved sleep quality, while caffeine intake, stress and irregular sleep-wake patterns decreased sleep quality. Less consistent results were reported regarding eating habits and sleep knowledge, while proper napping during the day might improve overall sleep quality [105].

These findings highlight the importance of extensive lifestyle interventions that address multiple factors influencing sleep quality, rather than focusing solely on sleep duration or timing.

7. Childhood Trauma and Adverse Experiences

Childhood trauma and adverse experiences represent some of the most potent risk factors for depression in young women, with effects that can persist well into adulthood. The early twenties may represent a particularly vulnerable period when the effects of childhood trauma interact with current stressors to trigger depression onset.

Long-term Effects of Childhood Trauma

Research has consistently documented the enduring effects of childhood trauma on adult mental health. CT was associated with a higher prevalence of depressive and anxiety disorders with increased comorbidity and chronicity. CT was linked to maladaptive personality characteristics and cognitions, stress systems’ dysregulations, advanced biological aging, poorer lifestyle, somatic health decline, and brain alterations. Potential CT mechanisms for psychopathology are found at various levels. Integrating them provides a better understanding of CT’s life-long impact [106] [107].

The broad nature of childhood trauma’s effects suggests that it creates vulnerability across multiple domains, making individuals more susceptible to depression when faced with additional stressors during young adulthood.

Specific Vulnerabilities in Young Women

Childhood trauma appears to create particular vulnerabilities for depression in young women. Experience either of a frightening event or of physical abuse in childhood was associated with an increased risk of first onset in younger adults (those aged ≤30). A gender difference (with women at increased risk) was revealed for first onsets of depression only and was found to decrease with increasing age, being no longer apparent in those aged over 50 [108] [109].

This age-related pattern suggests that childhood trauma may be particularly problematic for young women during the transition to adulthood, possibly due to the interaction between early vulnerabilities and current developmental challenges.

Neurobiological Mechanisms

Advanced research has revealed specific neurobiological mechanisms through which childhood trauma increases depression risk. Childhood trauma is a potent risk factor for developing depression in adulthood, particularly in response to additional stress. The central hypothesis underlying these studies was that early adverse experience in humans would lead to sensitization of central stress response systems, particularly corticotropin-releasing factor systems, leading to enhanced neuroendocrine, autonomic and behavioral responsiveness to stress as well as altered dynamics of the HPA axis. Such increased stress sensitivity would then lower an individual’s threshold to develop depression in relation to further stress [110] [111] [112]

This stress sensitization model provides a mechanistic explanation for why individuals with childhood trauma histories are more vulnerable to depression when faced with current stressors during young adulthood.

 

Intergenerational Transmission Pathways

Research has identified how trauma effects can be transmitted across generations, creating multiple pathways of risk. Childhood trauma was associated with increased risk of depression in adulthood. Prenatal and postnatal stress, indicated by maternal depression and family adversity, were associated with increased exposure to childhood trauma. Childhood trauma mediated all pathways from pre- and postnatal stress to offspring depression in adulthood, even after accounting for genetic risks [113] [114] [115].

These findings suggest that young women with trauma histories may be dealing not only with their own traumatic experiences but also with the intergenerational effects of family stress and trauma.

Specific Trauma Types and Depression Risk

Different types of childhood trauma appear to have distinct effects on depression risk. Childhood trauma victims exhibit low self-esteem, and experience depression and anxiety. Some deny their trauma history, while others create a false self-image and engage in alcohol and drug misuse in attempts to prevent their traumatic experiences from impacting their life. Early interventions may reduce trauma symptoms alongside sufficient and customized treatment strategies [116].

The variety of coping strategies, including denial and substance use, highlights the complex ways that trauma effects can manifest and potentially compound depression risk during young adulthood.

Emotion Regulation as a Mediating Factor

Research has identified emotion regulation difficulties as a key mechanism linking childhood trauma to adult depression. A considerable body of evidence suggests that childhood trauma is associated with the onset, symptom severity, and course of depression and anxiety symptoms. Despite the well-established relationship between childhood trauma and adulthood mental health problems, the specific mechanism underlying early life trauma relationship to later psychiatric problems is still unclear. The ability of emotion regulation is a possible mediator of the relationship between childhood trauma and later depression and anxiety symptoms. It appears that childhood trauma disturbs development of the ability to regulate emotions in a healthy manner [117] [118] [119].

This disruption in emotion regulation development may be particularly problematic during young adulthood, when individuals face multiple stressors and need strong emotional coping skills.

Protective Factors and Resilience

While childhood trauma creates significant risk, research has also identified factors that can promote resilience and reduce depression risk. LCA identified a four-class solution; with high adversity and high parental dysfunction being associated with poorer mental health outcomes while moderate parental dysfunction and low adversity groups scored at healthy levels. Childhood adversity had independent and additive contributions to depression and anxiety in older adulthood. Evidence suggests a long-term influence of childhood adversity on mental health that stretches into older adulthood. Assessment of childhood adversity may be useful when screening for mental illness [120] [121] [122].

The identification of different patterns of adversity and their outcomes suggests that intervention approaches should be tailored to specific trauma histories and that some individuals may be more resilient than others.

Clinical Implications

The evidence regarding childhood trauma and depression has important implications for clinical practice with young women. These findings indicate that reducing childhood trauma could be a target to decrease depression in the general population, and the focus should also be on families at high risk of experiencing pre- or postnatal stress, to provide them with better support [123].

Early identification of trauma histories and trauma-informed treatment approaches may be particularly important for preventing depression in young women who have experienced childhood adversity.

8. Genetic Predisposition

Genetic factors play a significant role in depression risk, with research consistently documenting moderate to high heritability for depression in women. Understanding genetic contributions is particularly important for young women, as genetic vulnerabilities may interact with environmental stressors during the transition to adulthood to trigger depression onset.

Heritability of Depression in Women

Twin studies have consistently documented significant genetic contributions to depression risk in women. The heritability of major depressive disorder (MDD) is reportedly 30–50%. However, the genetic basis of its heritability remains unknown [124]. Heritability estimates for depression scores were higher in women (0.34 and 0.37) than in men (0.13 and 0.21).

This pattern of higher heritability in women suggests that genetic factors may be particularly important for understanding depression risk in young women. There is consistent evidence that major depression is familial and population-based twin studies as well as hospital register-based twin studies find substantial heritability. However, there is also a large proportion of variation in liability left to be explained by nongenetic factors.

Racial and Ethnic Differences in Heritability

Research examining genetic factors across different ethnic groups has revealed important insights about depression heritability. Although the MDD heritability point estimate was higher among AA women than EA women in a model with paths estimated separately by race, the best fitting model was one in which additive genetic and non-shared environmental paths for AA and EA women were constrained to be equal. In spite of a marked elevation in the prevalence of environmental risk exposures related to MDD among AA women, there were no significant differences in lifetime prevalence or heritability of MDD between AA and EA young women.

These findings suggest that genetic contributions to depression may be similar across ethnic groups, even when environmental risk exposures differ significantly.

Gene-Environment Interactions

Contemporary research has moved beyond simple heritability estimates to examine how genetic factors interact with environmental influences. Meanwhile, the role of adverse life experiences in shaping depression risk is well-documented, including via gene-environment correlation. Building on theoretical work on dynamic and contingent genetic selection, we suggest that genetic influences may lead to differential selection into negative life experiences. Taken together, our findings suggest that the PGI of depression largely picks up the risk of behaviorally-influenced adversities, but to a lesser degree also captures other environmental influences. The results invite further exploration into the behavioral and interactional processes that lie along the pathways intervening between genetic differences and wellbeing.

This research suggests that genetic influences on depression may partly operate through their effects on behavior and environmental selection, rather than only through direct biological pathways.

Developmental Changes in Genetic Influence

Research examining genetic influences across development has revealed important patterns relevant to young women. The greater heritability for depression in pubertal girls, its genetic mediation over time, and the increase in genetic variance for life events may be one possible explanation for the emergence of increased depression among pubertal girls and its persistence through adolescence.

This finding suggests that genetic influences on depression may become more pronounced during puberty and persist into young adulthood, possibly due to hormonal changes that activate genetic vulnerabilities or gene-environment interactions that become more prominent during this developmental period.

Molecular Genetic Findings

While twin studies demonstrate genetic influences, identifying specific genes has proven challenging. The heritability of major depressive disorder is estimated at 30–40%, with mixed evidence for a stronger genetic risk for women than for men. To date, genome-wide association studies have not been very successful in identifying genetic markers of major depressive disorder, probably because of heterogeneity in risk factors [125].

Recent advances have begun to identify specific genetic variants associated with depression risk. Within SITH-1, a risk factor for MDD in human herpesvirus 6B (HHV-6B), we discovered a gene polymorphism with a large odds ratio for an association with MDD [126]. However, much work remains to understand the molecular basis of genetic risk.

Genetic Architecture and Polygenic Risk

Contemporary research recognizes that depression genetic risk likely involves many genes of small effect rather than single genes of large effect. There have been several recent studies addressing the genetic architecture of depression. This review serves to take stock of what is known now about the genetics of depression, how it has increased our knowledge and understanding of its mechanisms, and how the information and knowledge can be leveraged to improve the care of people affected.

Genome-wide association studies find that a large number of genetic variants jointly influence the risk of depression, which is summarized by polygenic indices of depressive symptoms and major depression. But PGIs by design remain agnostic about the causal mechanisms linking genes to depression.

Clinical Implications of Genetic Research

Understanding genetic contributions to depression has several important clinical implications. Although there seems little doubt that life events play a role in precipitating depression, studies that have attempted to examine familial liability along with social adversity find that environmental measures tend to be contaminated by genetic effects. Thus, the tendency to experience (or report) life events appears to be influenced by shared family environment, and for certain types of events there is a genetic component. The molecular genetic basis of liability to depression is an under-researched area, but some candidate gene studies show potentially promising results.

This research suggests that genetic factors may influence not only direct vulnerability to depression but also exposure to environmental risk factors, highlighting the complex interplay between genes and environment in depression development.

 

Discussion

Integration of Etiological Factors

The examination of multiple etiological domains reveals that depression in women during their early twenties emerges from a complex interplay of biological, psychological, social, and environmental factors rather than from any single causative element. This multifactorial model is consistent with contemporary understanding of depression as a heterogeneous condition with multiple pathways to onset.

The evidence suggests several key patterns in how these factors interact. First, certain factors appear to create general vulnerability that increases sensitivity to other stressors. For example, childhood trauma appears to sensitize stress response systems, making individuals more reactive to current stressors like academic pressure or relationship problems. Similarly, genetic predisposition may create vulnerability that is expressed when triggered by environmental factors.

Second, many risk factors operate through common pathways, particularly emotional dysregulation and stress sensitivity. Whether triggered by hormonal fluctuations, social media use, academic pressure, or relationship problems, many etiological factors appear to converge on similar psychological and biological mechanisms that ultimately manifest as depression.

Third, the early twenties represent a period of heightened vulnerability because multiple risk factors often co-occur during this developmental period. Young women may simultaneously face academic stress, relationship challenges, body image pressures, sleep disruption, and social media influences, creating a “perfect storm” of risk factors that can overwhelm coping resources.

Developmental Considerations

The timing of depression onset during the early twenties appears to reflect the interaction between ongoing biological maturation and environmental demands. The difference begins in early life and persists through to mid-life, and as such, these reproductive years have been labelled by some as a ‘window of vulnerability’ [127]. This vulnerability window coincides with several important developmental processes.

Neurobiologically, the brain continues to mature throughout the early twenties, particularly in areas responsible for emotional regulation and executive function. This ongoing development may create temporary vulnerabilities that are exploited by environmental stressors. Additionally, the early twenties represent a period of identity consolidation and role transitions that can create psychological stress and uncertainty.

The social context of early adulthood has also changed significantly in recent decades, potentially creating new sources of stress and vulnerability. Extended education, delayed marriage and childbearing, economic uncertainty, and social media exposure represent relatively new environmental pressures that may interact with existing vulnerabilities to increase depression risk.

Gender-Specific Vulnerabilities

The evidence suggests several mechanisms that may explain why women show elevated depression rates during their early twenties. Hormonal factors clearly play a role, with menstrual cycle-related mood changes and hormonal sensitivity creating biological vulnerability. However, hormonal factors alone cannot explain the full gender difference, suggesting that psychosocial factors are also important.

Young women appear to face unique social pressures around appearance, relationships, and achievement that may contribute to depression risk. The intersection of academic pressure with concerns about body image, social comparison through social media, and relationship stress may create a particularly challenging constellation of stressors for young women.

Additionally, young women may be more sensitive to interpersonal stressors and more likely to experience certain types of trauma and adversity. The evidence suggests that women show stronger relationships between sleep problems, stress, and depression, possibly reflecting greater physiological reactivity to environmental stressors.

Implications for Prevention and Intervention

The multifactorial nature of depression in young women suggests that prevention and intervention efforts should address multiple domains rather than focusing on single risk factors. Universal prevention approaches might target sleep hygiene, stress management, social media literacy, and emotional regulation skills that could provide protection across multiple risk domains.

Selective prevention efforts might focus on young women with specific risk factors such as trauma histories, family histories of depression, or significant academic or relationship stress. These approaches could provide additional support and skill development during vulnerable periods.

Indicated prevention for young women showing early depression symptoms might involve comprehensive assessment across all etiological domains to identify specific risk factors and develop targeted interventions. The evidence suggests that addressing sleep, stress, relationship issues, and trauma history simultaneously may be more effective than focusing on symptoms alone.

Limitations and Future Directions

Several limitations should be acknowledged in this analysis. First, the evidence base varies significantly across different etiological domains, with some areas having extensive research while others remain relatively understudied. Second, most research is conducted in college populations, which may not represent all young women in their early twenties.

Third, the rapidly changing social and technological environment means that some risk factors (particularly social media influences) may evolve faster than research can document their effects. Fourth, the complex interactions between risk factors are difficult to study and may vary significantly across individuals and contexts.

Future research should prioritize longitudinal studies that can track the development of depression across the early twenties and identify critical periods and pathways. Studies examining gene-environment interactions and epigenetic mechanisms could provide insights into individual differences in vulnerability and resilience.

Additionally, research examining cultural and ethnic differences in depression etiologies could inform culturally appropriate prevention and intervention approaches. Finally, intervention research testing comprehensive approaches that address multiple risk factors simultaneously could provide evidence for more effective treatment and prevention strategies.

Conclusion

Depression in women during their early twenties represents a complex phenomenon resulting from the interaction of multiple biological, psychological, social, and environmental factors. This analysis has identified eight primary etiological domains that contribute to depression risk during this critical developmental period: hormonal and reproductive factors, academic and transitional stress, social media and digital influences, relationship dynamics, body image concerns, sleep disturbances, childhood trauma, and genetic predisposition.

The evidence reveals that these factors rarely operate in isolation but rather interact in complex ways to create vulnerability or resilience. The early twenties represent a particularly vulnerable period due to the convergence of biological maturation, social role transitions, and environmental stressors that characterize this developmental stage. Young women appear to be especially vulnerable due to hormonal influences, gender-specific social pressures, and potentially greater sensitivity to interpersonal and environmental stressors.

Key findings from this analysis include:

1. Multifactorial Causation: Depression in young women emerges from the interaction of multiple risk factors rather than single causes, requiring thorough assessment and intervention approaches.

2. Developmental Vulnerability: The early twenties represent a “window of vulnerability” where biological, psychological, and social factors converge to create heightened depression risk.

3. Gender-Specific Mechanisms: Young women face unique combinations of hormonal influences, social pressures, and environmental stressors that contribute to elevated depression rates.

4. Mediating Pathways: Many risk factors operate through common mechanisms such as emotional dysregulation, stress sensitivity, and sleep disruption, suggesting shared intervention targets.

5. Bidirectional Relationships: Many risk factors show bidirectional relationships with depression, creating cycles that can perpetuate or amplify symptoms over time.

The clinical implications of these findings suggest that effective prevention and intervention for depression in young women should:

• Address multiple risk domains simultaneously rather than focusing on isolated factors

• Recognize the developmental context and provide appropriate support during transitions

• Include gender-specific considerations in assessment and treatment planning

• Integrate biological, psychological, and social intervention components

• Address underlying mechanisms such as stress sensitivity and emotional regulation

Future research priorities should include longitudinal studies tracking depression development across early adulthood, investigation of gene-environment interactions, examination of cultural and ethnic differences in depression etiologies, and testing of comprehensive intervention approaches that address multiple risk factors simultaneously.

Understanding the complex etiologies of depression in young women is essential for developing more effective prevention and intervention strategies. As depression rates continue to rise in this population, addressing the multifaceted nature of risk factors becomes increasingly critical for promoting mental health and preventing long-term consequences. The evidence suggests that comprehensive, developmentally-informed approaches that recognize the unique challenges facing young women during their early twenties offer the greatest promise for reducing depression burden and promoting resilience during this critical life stage.
