Relationship between Untreated Dental Caries and Weight and Height of 6- to 12-Year-Old Primary School Children in Bangladesh

Table 4

Odds ratio of association of underweight (weight-for-age <−2) with untreated caries adjusted for different variables.

Age group	Model	Odds ratio	95% confidence interval	𝑃 value
6–8 years	First	1.67	1.19, 2.33	<0.05
	Second	1.58	1.13, 2.23	<0.05
	Third	1.61	1.14, 2.27	<0.05
9–12 years	First	1.46	1.08, 1.98	<0.05
	Second	1.45	1.07, 1.96	<0.05
	Third	1.47	1.08, 2.00	<0.05

Weight-for-age z-score <−2 is under weight and ≥−2 is normal weight. Model 1: adjusted for sex. Model 2: adjusted for area description, socioeconomic class, and escape of meal per week. Model 3: adjusted for tooth cleaning frequency and ever visited doctor.
