  1. Mediation analysis performed with each mediator separately. Results adjusted for age. Estimates statistically significant at p < 0.05 in bold.
  2. aPath a represents the association between education as a predictor and mediator as the outcome.
  3. bPath b represents the association between mediators as predictors and adiposity as the outcome.
