Model 1 was adjusted for no covariates;

Model 2 was adjusted for race, marital status and education;

Model 3 was adjusted for covariates in Model 2+diabetes,blood pressure, PIR, total water,total kcal,total sugar, total fat, smoked, physical activity, alcohol use, serum cholesterol, coronary artery disease, asthma, testosterone and estradiol were adjusted.

Model 4:The covariates that need to be adjusted were consistent with those in Model 3.
