Figure 4 Mediation model. A: Mediation model of diet, body dissatisfaction, and depression. Path diagram of direct and indirect effects of dietary behavior on depression. Standardized coefficients show diet influences depression through body dissatisfaction (indirect effect β = 0.0137) and a direct pathway (β = 0.0492), with mediation accounting for 218% of the total effect (^bP < 0.01); B: Mediation model of physical activity, body dissatisfaction, and depression. Path diagram of direct and indirect effects of physical activity on depression. Standardized coefficients show physical activity influences depression through body dissatisfaction (indirect effect β = -0.0164) and a direct pathway (β = -0.0517), with mediation accounting for 241% of the total effect (^cP < 0.01).
