CI, confidence interval.

^aHigh‐intensity physical activity was defined as vigorous exercise for more than 3 times/week; moderate‐intensity physical activity was defined as exercise with moderate intensity for more than 5 d/wk.

^bAbdominal obesity was defined as waist circumference ≥90 cm in men and ≥85 cm in women.

^cAdjusted for age, sex, current smoking, alcohol drinking, exercise, income level, and history of diabetes and hyperlipidemia.
