OR, odds ratio; CI, confidence interval; MET, metabolic equivalent.
Model 1 adjusted for age and gender.
Model 2 adjusted for age, gender, race, BMI, educational level, smoking status, alcohol consumption, dietary pattern, daily total energy intake, hypertension, total work-related physical activity, and walking or bicycling for transportation.
