Odds ratio for the risk of NAFLD by the level of physical activity (< 150 min/week vs. ≥ 150 min/week) or muscle strength exercise (< 2/week vs. ≥ 2/week) in predefined subgroups. Models were adjusted for age (continuous), sex, body mass index (continuous), elevated waist circumference (yes vs. no), elevated triglycerides (yes vs. no), reduced high-density lipoprotein cholesterol (yes vs. no), diabetes mellitus (yes vs. no), hypertension (yes vs. no), income levels (Q1, Q2, Q3, and Q4), education (elementary or lower, middle school, high school, college or higher), smoking (current, ex-smoker, and never smoker), alcohol consumption (< 10 g/day vs.  10 g/day), total physical activity (< 150 min/week vs. ≥ 150 min/week), and muscle strength exercise (< 2/week vs. ≥ 2/week). For specific domains of physical activity, other domains were adjusted as follows: (1) For recreation activity, travel and work activities (< 150 vs. ≥ 150 min/week) were adjusted; (2) For travel activity, recreation and work activities (< 150 vs. ≥ 150 min/week) were adjusted; and (3) for work activity, recreation and travel activities (< 150 vs. ≥ 150 min/week) were adjusted.
