The data were expressed with odds ratios (OR) and corresponding 95% confidence intervals (CI).

Body mass index calculated as weight in kilograms divided by height in meters squared and categorized as normal weight (18.5–24.9), overweight (25.0–29.9), and obesity (30.0). Waist circumference categorized as normal (≤88 cm) and high (>88 cm) for women, as normal (≤102 cm) and high (>102 cm) for men.

Model 1: No covariates were adjusted; Model 2: Age, race/ethnicity, education, smoking and drinking status were adjusted; Model 3: Model 2 + hypertension and hyperlipidemia status.
