Objectives-To prospectively investigate associations between overweight and depressive symptoms in Asian and Hispanic adolescents.
Methods-Data included 780Hispanic and 375 Asian students. Structural equation model was used to prospectively explore moderation effects of gender, ethnicity, and acculturation on associations of overweight, body image dissatisfaction, and depressive symptoms.Results-Significant mediation effect was found only in Asian girls (mediation effect=0.16, P<0.05) and girls with high acculturation (mediation effect=0.17, P<0.05). Overweight significantly predicted higher body image dissatisfaction, which in turn was significantly related to depressive symptoms.
Conclusion-Our findings help understanding the association of overweight and experience of depressive symptoms.Keywords overweight; depressive symptoms; body image; acculturation Pediatric overweight has been associated with depression and anxiety; 1 peer isolation and discrimination; 2,3 low self-esteem, 4 self-concept, 5 and social cooperation skills; 6 family disharmony; 7 dislike of school or trouble with teachers; 7 and poor health-related quality of life. 8 The underlying mechanisms have been presumably related to the reflected selfappraisal hypothesis and social comparison theory, 9-11 which mainly involve cultural norms and social desirability of ideal weight and the process of self-appraisal and social comparison of body image and physical attractiveness. The reflected self-appraisal hypothesis is based on Cooley's concept of the "looking-glass self," which posits that an individual's self-concept, defined as the internalized view we have of ourselves, is socially constructed through the judgment of others and self-appraisal. [10][11][12] The Social Comparison Theory suggests that people engage in a process of self-evaluation, comparing themselves to others who they believe possess desirable social and cultural traits and, in turn, engage in Address correspondence to Dr Xie, School of Community and Global Health, Claremont Graduate University, 180 East Via Verde, Suite 100, San Dimas, CA 91773. bin.xie@cgu.edu.

Given that overweight is viewed as a less desirable and more stigmatizing characteristic in the American culture, the process of self-appraisal or social comparison may explain why overweight individuals are at a height-ened risk for negative psychological and behavioral outcomes, beyond the health risks of overweight. 13,14 These underlying mechanisms are especially assumed to be operative in ...
