Abbreviations: BMI, body mass index; WHR, waist-hip ratio; IDF, International Diabetes Federation; OR, odds ratio; 95% CI, 95% confidence interval.

^aAbdominal obesity was defined by the International Diabetes Federation (IDF) criteria: WC ≥ 90 cm for men and WC ≥ 80 cm for women.

^bModel 1: Unadjusted

^cModel 2: adjusted for demographic factors including age, sex, and education level.

^dModel 3: adjusted for demographic & lifestyle factors including age, sex, education level, recreational physical activity participation, alcohol consumption, use of energy drinks, and cigarette smoking.

^eModel 4: Model 3+blood pressure

^fModel 5: Model 4+psychological distress (evaluated by the General Health Questionnaire 12-item scale).

^gModel 6: Model 5+WHR/BMI (When overweight/obesity or obesity (defined from BMI) was the outcome variable, waist-to-hip ratio (WHR) but not BMI was adjusted for. When abdominal obesity was the outcome variable, BMI but not WHR was adjusted for.
