  1. Base model includes: Baseline BMI (kg/m2), age, education, duration of follow-up, history of cardiometabolic disease, Social Support index, physical activity, self-reported physical health status and extraversion
  2. aCovariates, associated with mood disorder based on a univariate models (at p < 0.1) were added one at a time to the base model to test for mediating
