Data from the National Health and Nutrition Examination Survey 2007-2018 were used to develop a ML\u2013based T2D risk prediction model among individuals with depressive symptoms (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 790). Nine ML algorithms were compared, incorporating Boruta feature selection, 10-fold cross-validation, and SHapley Additive ExPlanations (SHAP) analysis to identify and interpret key predictors. Moderation analysis was conducted to evaluate whether the triglyceride-glucose (TyG) index and physical activity (PA) influence the relationship between the predictor and the outcome.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Inverse variance weighted MR analysis showed that genetic liability to depression increased the risk for T2D (OR = 1.38, 95% CI: 1.01\u20131.90), while no significant causal effect was found in the reverse direction. MVMR analysis showed that PA was inversely related to T2D risk (OR = 0.98, 95% CI: 0.96\u20130.99,\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      = 0.001). Boruta feature selection identified age and the TyG index as significant predictors.

SHAP analysis confirmed that the TyG index had the highest feature importance (mean SHAP value = 0.099), followed by age (0.025).
