Unhealthy weight loss behaviors (UWLB) are a prominent health compromising action that has been prevalent among college females. Depression is a variable that has demonstrated a direct relationship with UWLB. However, the reason why this linkage exists remains to be fully investigated. Based on past research connecting sleep difficulties to depression and UWLB, sleep difficulties may be one key mediating variable influencing the depression to UWLB pathway. To examine this possibility, survey data were obtained from a sample of 928 females attending one ethnically diverse southern California University. Mediation analysis was used to test the hypotheses that there would be: 1) a significant relationship between depression and UWLB, 2) a significant relationship between depression and sleep difficulties, 3) a significant relationship between sleep difficulties and UWLB, and 4) in the final mediation model, a relationship between depression and UWLB mediated by sleep difficulties. Results showed a significant association between depression and vomiting or laxatives to lose weight, but no significance was found between depression and dieting or diet pills. Those who had depression were more likely to experience more sleep difficulties. Sleep difficulties was significantly associated with dieting to lose weight. Mediation testing through logistic, linear regression, and RMediation revealed the depression to UWLB relationship was not mediated by sleep difficulties. Partial mediation was indicated in self-described weight and desire to lose weight in the RMediation model. The results suggest further research is needed to better understand the depression to UWLB pathway.
