Abbreviation: DMFT decayed, missing, and filled permanent teeth, CI conference interval, BMI body mass index, WHR waist-hip ratio, WHtR Waist-height ratio, TRSKF triceps skinfold thickness
Dependent variable (categorical data): Adiposity indicess; BMI was classified into underweight/normal weight group vs overweight/obese group (event group); WHR and TRSKF was classified by median values (higher 50% is event group)
Independent variable: DMFT (continuous data), gender, full time employment of both parents, household monthly income, frequency of tooth brushing, use of fluoride toothpaste, frequency of mouth rinse, frequency of flossing, amount of grains intake, amount of vegetables intake, amount of fruit intake, amount of milk intake, amount of meat intake, amount of oil intake, and amount of sweet intake (categorical data)
*P < 0.05, **P < 0.01
P values were calculated through binary logistic regression
