For the age-adjusted model, it was adjusted for baseline (1996) age (years) and waist circumference (continuous, cm). Data on weight training was presented in 2008 without adjustment for PA at baseline (1996).
Multivariate model 1 is adjusted for the same variables in the age-adjusted model in addition to total average alcohol intake (1994, 2006), (0; >0-<2.5; 2.5-5; >5-10; >10 g/day; missing); sugar-sweetened beverage intake (1994, 2006), (0; >0-0.5; >0.5-1; >1 servings/day); percent energy of trans-fat (1994, 2006), (quintiles); energy-adjusted fibers (1994, 2006) (quintiles g/day), energy-adjusted glycemic load (1994, 2006) (quintiles); smoking (1996, 2008) (never; past; nonsmoker, unknown past history; current; missing), anti-depressant intake (1996, 2008) (never; current; past), percent energy of protein intake, (1994, 2006) (quintiles), sleep duration (2000, 2008) (continuous, hours/day), in addition to slow walking, TV watching, moderate-to-vigorous aerobic activity, and other activities (all in 1996, 2008), and weight training (1996) (all categorical, min/day).
Multivariate model 2 is adjusted for the same variables in multivariate model 1 in addition to weight (1996, 2008) (continuous, kg).
For the body weight change outcome, the age-adjusted model was adjusted for baseline (1996) age (years) and body weight (continuous, kg). Data on weight training was presented in 2008 without adjustment for PA at baseline (1996).
Model 3 is adjusted for the same covariates in model 1 except for waist circumference and in addition to baseline height (m) and weight (kg).
Same as model 3 in addition to waist circumference (1996, 2008) (continuous, cm).
