Model 1: Linear regression models adjusted for baseline values of AHEI, age, sex, BMI, MET hours per week, total energy intake as well as change from baseline to year one of MET hours per week and total energy intake
Model 2: Linear regression models adjusted for Model 1 covariates as well as baseline values of education, smoking status, family history of diabetes, alcohol use
Model 3: Also adjusted for baseline values of dietary fiber, carbohydrate, total fat and saturated fat at baseline and change to year 1 of each
^aAlso adjusted for treatment group
^bAlso adjusted for race/ethnicity
