摘要

Background

Body image plays a significant role in emotional and behavioral health. This study examined the short-term longitudinal association between body image satisfaction and disordered eating behaviors (DEBs) among students at two Tibetan universities, considering theory-driven sequential indirect roles of anxiety and depressive symptoms.

Methods

A longitudinal survey was conducted among 2,993 first- and second-year university students in Xizang, with a baseline assessment in September 2021 and a follow-up in December 2021. Participants completed standardized questionnaires assessing body image satisfaction, anxiety, depressive symptoms, and DEBs. Statistical analyses included t-tests, ANOVA, Pearson correlations, and structural equation modeling (SEM) using robust maximum likelihood estimation (MLR) with bootstrap confidence intervals (1,000 resamples).

Results

SEM analyses indicated that body image satisfaction was prospectively associated with lower DEBs (β = −0.050, 95% CI = − 0.099 to − 0.008). Depressive symptoms independently mediated this association (β = −0.010, 95% CI = − 0.019 to − 0.003), whereas the indirect pathway through anxiety alone was not significant (β = −0.005, 95% CI = − 0.014 to 0.006). A sequential indirect pathway involving anxiety and depressive symptoms was significant (β = −0.033, 95% CI = − 0.047 to − 0.021). The total indirect effect was also significant (β = −0.048, 95% CI = − 0.065 to − 0.033). Model fit was acceptable (CFI = 0.961, TLI = 0.911, RMSEA = 0.060, SRMR = 0.021).

Conclusions

These findings highlight the potential roles of anxiety and depressive symptoms in the association between body image satisfaction and DEBs, suggesting that interventions targeting body image and emotional health may help reduce the risk of DEBs.
