Model 1 adjusted for age, sex, and BMI. Model 2 further adjusted for household income, alcohol consumption, current smoking, and frequency of resistance exercises. Model 3 further adjusted for hypertension, diabetes, serum total cholesterol, and log transformed hsCRP. Model 4 further adjusted for total calorie intake and the use of dietary supplements. Abbreviations: OR, odds ratio; CI: confidence interval; BMI, body mass index; hsCRP, high sensitivity C-reactive protein.
