  1. Data presented as mean ± standard deviation or unadjusted/adjusted mean difference compared to referent group (<2 h/day) ± standard error
  2. P1 = Sometimes vs. Never of Seldom; P2 = Often or Always vs. Never or Seldom
  3. CIMT carotid intima-media thickness
  4. Model 1: Adjusted for age and sex
  5. 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
  6. 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
  7. Model 4: Adjusted for covariates in model 3 plus levels of moderate to vigorous physical activity (poor, intermediate, or ideal)
  8. Model 5: Adjusted for covariates in model 4 plus television viewing category (<2, 2–4, or >4 h/day)
