Unadjusted and adjusted OR and 95% CI and statistical differences were analyzed using logistic regression without and with adjusting for covariates.
1)
Model 1, no adjustment; Model 2, adjusted for age, household income level, frequency of teeth brushing, and eat-out frequency; Model 3, adjusted for all covariates in model 2 plus, BMI, energy intake, and daily nutrient intakes (protein, fat, carbohydrate, calcium, potassium, iron, sodium, phosphate, dietary fiber, vitamin C, β-carotene, and vitamin A).
