Abbreviations: BMI, body mass index; OR, odds ratio; CI, confidence interval; WHR, waist-to-hip ratio.

BMI<25 kg/m² served as the reference group in the WHO criteria.

BMI<23 kg/m² served as the reference group in the Asian criteria.

Model 1: Unadjusted

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

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

Model 4: Model 3+blood pressure

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

Model 6: Model 5+WHR.
