Model 1: no covariates were adjusted. Model 2: adjusted for age, sex, and race. Model 3: adjusted for age, sex, race, education level, alcohol consumption, smoking, diabetes, high blood pressure, coronary heart disease, cancer, PIR, triglycerides, total cholesterol, HDL-C, and LDL-C

Abbreviations: PIR Ratio of family income to poverty, HDL-C High-density lipoprotein cholesterol, LDL-C Low-density lipoprotein cholesterol
