University students represent a demographic facing heightened psychological distress, with body dissatisfaction emerging as a significant contributing factor to their overall well-being. A recent comprehensive synthesis of contemporary evidence, exploring mediating mechanisms and systemic gaps, underscores the urgent need for improved clinical practices and institutional support within higher education settings. This scoping review, conducted between March and April 2025, meticulously examines the scientific literature on body self-perception and mental health among university students, aiming to identify core findings, underlying pathways, and crucial research omissions. The study, adhering to the PRISMA-ScR guidelines, systematically searched major academic databases including Scopus, PubMed/MEDLINE, PsycINFO, SciELO, and Redalyc. It encompassed peer-reviewed quantitative, qualitative, and mixed-methods studies, alongside previous reviews, published in English and Spanish from 2014 to 2025. Grey literature and unpublished theses were excluded to maintain a focus on rigorously vetted research. Key Findings Highlight Pervasive Links Between Body Dissatisfaction and Psychological Distress The review identified 18 studies, which were thematically clustered to reveal consistent patterns. A primary finding is the strong and consistent association between body dissatisfaction and elevated levels of depression and anxiety across diverse cultural contexts. This phenomenon is not confined to specific regions but appears to be a global concern affecting university students irrespective of their geographical location. Crucially, the research pinpointed self-esteem and fear of negative evaluation as primary mediating factors in this relationship. This suggests that negative perceptions of one’s body can erode self-worth and heighten anxieties about how others perceive them, creating a cycle that negatively impacts mental health. Beyond depression and anxiety, body dissatisfaction was also significantly linked to more severe outcomes, including suicidal ideation, impaired sleep quality, and social dysfunction. Methodological Landscape Reveals Areas for Improvement While the findings are significant, the review also highlighted methodological limitations within the existing research. The majority of studies employed cross-sectional, quantitative designs, which, while useful for identifying correlations, do not allow for definitive causal conclusions. Furthermore, a significant gap was identified in the exclusion of gender-diverse populations, with most studies remaining anchored in the gender binary. This oversight limits the understanding of how body image concerns and their mental health consequences manifest across the full spectrum of gender identities. The University as a Nexus of Stress and Vulnerability University students are in a critical developmental stage known as emerging adulthood, characterized by identity exploration and increased sensitivity to social evaluation. This period is often accompanied by significant stressors, including academic pressures, social adjustment, and the pursuit of independence. In this context, body image can become a central component of self-concept, amplified by increased social comparison and exposure to appearance-related norms, particularly within the digital realm. The pervasive cultural ideals promoting extreme thinness or muscularity further exacerbate these pressures, making university environments fertile ground for body dissatisfaction. Theoretical frameworks such as the Tripartite Influence Model and Objectification Theory provide valuable lenses through which to understand these dynamics. The Tripartite Influence Model posits that societal influences from family, peers, and media contribute to the internalization of beauty ideals and social comparison, which are proximal pathways to body dissatisfaction and psychological distress. Objectification Theory, conversely, highlights how societal socialization that emphasizes appearance can lead to self-objectification, body surveillance, and shame, all linked to anxiety and depression. While these models offer robust foundations, the current empirical evidence applied specifically to the university context remains fragmented, hindering a precise understanding of how these processes operate within this population. Mediating Mechanisms: A Closer Look Two key mediating pathways are particularly relevant in the contemporary university landscape. Firstly, social media, with its emphasis on highly visual content, fosters appearance-based social comparison, which is consistently linked to increased body dissatisfaction and negative affect. Secondly, the internalization of unrealistic aesthetic ideals, often promoted through digital platforms, acts as a significant mediator between exposure to such content and psychological distress. Meta-analyses confirm a consistent, albeit small to moderate, association between social media use and body image disturbance in young people, with highly visual platforms showing more pronounced effects. However, research within university populations often overlooks the measurement invariance of assessment instruments across sociodemographic variables like gender, sexual orientation, or weight status, thus limiting the comparability of findings. Broader Mental Health Implications Body dissatisfaction is not merely an aesthetic concern; it is a potent risk factor for severe psychological distress. The review’s findings underscore its link to a range of harmful consequences for young individuals, including elevated rates of depression and anxiety. These associations have been observed in diverse populations, suggesting a global pattern. For men, concerns about muscularity are particularly relevant and have been linked to depressive affect and anxiety. These relationships are not static and can vary significantly based on sex, age, and socioeconomic status. The concept of positive body image, characterized by body appreciation and acceptance, is gaining traction as a promising avenue for intervention, linked to greater well-being. However, the majority of studies focus on negative aspects in isolation, leading to a paucity of integrated understanding of their interaction within the university experience. Geographical and Temporal Trends in Research The geographical coverage of the reviewed studies reveals a significant concentration in Asia (61%), followed by Latin America and North America (each 17%), and a limited presence in Europe (6%). Notably, Africa was underrepresented in this specific subset of studies. The publication timeline shows a clear surge in recent research, with 83% of the studies published between 2022 and 2024, peaking in 2023, indicating a growing academic interest in this area. Sample sizes varied, with a combined total of over 14,514 students across the 18 studies. The median sample size was 454, with several studies including over 1,000 participants. While most studies report sex distribution, there is a predominant representation of female students, with only one all-male study and one focused on non-binary individuals identified. The majority of articles were published in English, with three in Spanish. Methodological Quality and Limitations A formal quality appraisal using the Joanna Briggs Institute (JBI) Critical Appraisal Tool revealed that 17 of the 18 studies were classified as moderate in quality. This classification was primarily due to two systemic limitations: the absence of explicit clinical exclusion criteria for pre-existing eating disorders and the failure to adjust for Body Mass Index (BMI) as a primary confounder in multivariate models. While the internal consistency of the instruments used was high, the lack of control for these physiological and clinical variables limits the ability to establish robust directional associations in the cross-sectional data. The predominant reliance on quantitative cross-sectional designs, with limited qualitative and interventional studies, poses a significant challenge. The near absence of longitudinal research restricts causal inferences, and the heterogeneity of instruments, coupled with irregular use of key covariates, introduces noise and potential bias. Furthermore, the geographical concentration in Asia and underrepresentation of certain regions, along with a majority of female samples and limited analyses by gender identity, underscore the need for more diversified research. Implications for Higher Education Institutions The findings of this scoping review carry significant implications for Higher Education Institutions (HEIs). There is an urgent need for HEIs to transition from reactive to proactive mental health frameworks. This includes integrating biopsychosocial screening protocols within university health services to enable early detection of body-related distress. Critical media literacy interventions are also essential to dismantle the cognitive mechanisms of social comparison and the internalization of idealized body standards. Furthermore, psychological support services must adopt an intersectional and inclusive lens, integrating body-neutrality and gender-affirming practices. This approach will better address the unique stressors faced by students across diverse body types and gender identities. By embedding these evidence-based strategies, universities can foster a more resilient academic environment that acknowledges the complex interplay between physical self-perception and psychological well-being. Future Research Directions The review highlights several critical gaps for future research. There is a pressing need for longitudinal studies to establish causal relationships between body image and mental health outcomes. Research should also prioritize the inclusion of underrepresented populations, including gender-diverse individuals, and expand geographical coverage to encompass under-researched regions. Additionally, future studies should adopt multimodal designs that integrate objective physical health markers, such as BMI and clinical health records, alongside self-report measures. This will move beyond descriptive correlations towards more robust predictive models. The development and evaluation of evidence-based interventions, including digital and mindfulness-based protocols, tailored for the university environment, are also crucial. Conclusion: A Call for Integrated and Inclusive Mental Health Support In conclusion, body dissatisfaction stands as a potent risk factor for severe psychological distress among university students, operating through complex cognitive and digital mediators. The synthesized evidence strongly supports the need for universities to implement proactive mental health frameworks. This includes integrated screening, inclusive and gender-affirming counseling policies, and educational initiatives that promote media literacy and body appreciation. Addressing body image concerns is not merely about aesthetics; it is a fundamental component of fostering comprehensive student well-being and academic success. The path forward demands a commitment to rigorous, diversified research and the systematic integration of evidence-based interventions into the fabric of higher education.
