OR odds ratio, CI confidence interval
a Model 1: adjusted for age, sex, level of education
b Model 2: adjusted for Model 1 and diabetes, stroke, heart diseases, arthritis, osteoporosis/hip fracture, cognitive impairment, sarcopenia
c Model 3: adjusted for Model 2 and body mass index, waist circumference, percent body fat, visceral fat area
