  1. Model 1: Adjusted for age, sex, BMI, and occupations at baseline, and cumulative average total energy intake
  2. Model 2: Adjusted for variables in model 1 plus education level, region, smoking status, SBP, DBP, urban or rural residents, physical activity (low, moderate, high) at baseline, as well as cumulative average fiber intake, and sodium to potassium intake ratio, and fat intake (% energy)
