CIMT carotid intima-media thickness
Model 1: Adjusted for age and sex
Model 2: Adjusted for covariates in model 1 plus education < high school, income < $50,000, fulltime employment, heavy alcohol drinking, current smoking, energy intake, history of myocardial infarction, and statin use
Model 3: Adjusted for covariates in model 2 plus diabetes, hypertension, BMI, total cholesterol, HDL cholesterol, LDL cholesterol, and estimated glomerular filtration rate <60 ml/min/1.73 m2
Model 4: Adjusted for covariates in model 3 plus levels of moderate to vigorous physical activity (poor, intermediate, or ideal)
Model 5: Adjusted for covariates in model 4 plus occupational sitting category (never/seldom, sometimes, or often/always)
