Model 1 adjusted for enrollment age, residence, education, and marital status for adjustment. Model 2 adjusted for enrollment age, residence, education, marital status, smoking, drinking, menopause, antihypertensive medication, physical activity, BMI, WC, BFP, VAI, BMR, HR, and sleeping duration. BMI = body mass index; BMR = basal metabolism rate; WC = waist circulation; BFP = body fat percentage; VAI = visceral adiposity index; HR = heart rate.
