Logistic regression models are adjusted for age, race/ethnicity, history of diabetes, physical activity, baseline use of cholesterol lowering or hypertension medications (see text for details)
% change from baseline was calculated as mean change from baseline divided by the mean value at baseline.
P-value was calculated based on multivariate regression model using the five components of Metabolic Syndrome simultaneously in continuous scales as outcomes, adjusted for age, race/ethnicity, history of diabetes, physical activity, use of hypertension or cholesterol medications at baseline. The multivariate regression model provides an overall test for the intervention impact on all five components as a whole. Adherence was defined based in participation in intervention activities (see text for details).
