BMI, body mass index; MET, metabolic equivalent; T, tertile.

^aMantel-Haenszel chi-square test was used for categorical variables and linear regression analysis for continuous variables.

^bBMI was calculated as body weight (kilograms) divided by the square of body height (meters).

^cEnergy adjustment was performed according to the residual method.
