Crude model: Weighted univariable logistic regression model.

Model 1: Weighted multivariable logistic regression model adjusted for age, gender, race, education, and PIR.

Model 2: Weighted multivariable logistic regression model adjusted for age, gender, race, education, PIR, drink, physical activity, hypertension, diabetes, dyslipidemia, CVD, bone loss around teeth, BMI, fiber intake, last dental visit, dental care, frequency of using dental floss.
