Data are shown as the mean±standard deviation for continuous variables and number (%) for categorical variables.

BMI, body mass index; WHR, waist hip ratio; MMD, muscle mass deficit; BMD, bone mineral density.

aP-value by independent t-test for continuous variables and by χ2 test for categorical variables (<0.05).

bOsteoporosis is defined as T-score ≤-2.5.
