The relative importance of body change strategies, weight perception, perceived social support, and self-esteem on adolescent depressive symptoms: longitudinal findings from a national sample.

OBJECTIVE: This study aimed to evaluate the relative importance of body change strategies and weight perception in adolescent depression after accounting for established risk factors for depression, namely low social support across key adolescent contexts. The moderating effect of self-esteem was also examined.
METHODS: Participants (N=4587, 49% female) were selected from the National Longitudinal Study of Adolescent Health. Regression analyses were conducted on the association between well-known depression risk factors (lack of perceived support from parents, peers, and schools), body change strategies, weight perception, and adolescent depressive symptoms one year later.
RESULTS: Each well-known risk factor significantly predicted depressive symptoms. Body change strategies related to losing weight and overweight perceptions predicted depressive symptoms above and beyond established risk factors. Self-esteem moderated the relationship between trying to lose weight and depressive symptoms.
CONCLUSION: Maladaptive weight loss strategies and overweight perceptions should be addressed in early identification depression programs.
