Abbreviation: BMI, body mass index; WC, waist circumference; SBP, systolic blood pressure; DBP, diastolic blood pressure. Model1: adjusted for age and sex. Model2: adjusted for age, sex, current smoking, current drinking, exercise regularly, type 2 diabetes, cardiovascular disease, family history of hypertension, and total energy intake in the HPHS and HDNNCDS; Adjusted for age, sex, ethnicity, exercise regularly, current smoking, current drinking, type 2 diabetes, cardiovascular disease, and total energy intake in the NHANES.
