Values are the OR (95% CI). * p values by complex-samples logistic regression model. Model 1, adjusted for age and sex. Model 2, adjusted for model 1 plus BMI. Model 3, adjusted for model 2 plus total calorie intake, sleep duration, smoking, alcohol, education level. Model 4, adjusted for model 3 plus diabetes mellitus, cardiovascular disease, hypertension, arthritis. Model 5, adjusted for model 4 plus central obesity. OR, odds ratio; NAFLD, non-alcoholic fatty liver disease; HEPA, health-enhancing physical activity; BMI, body mass index.
