ABSTRACT
OBJECTIVE:
The aim of the study was to examine the relationship between caries experience and obesity in Mexican schoolchildren aged 8-12 years. STUDYDESIGN:
This is a cross-sectional study.METHODS:
This study was conducted on 522 schoolchildren selected from public schools. The prevalence of caries was evaluated by applying the decayed, missing and filled teeth (DMFT) index and ascertaining the subjects' dental caries experience from the mean DMFT value. Socio-economic data were collected from the parents, with data on the children's characteristics collected from them via a questionnaire. Their weight and height were then measured and used to calculate their body mass index (BMI)-for-age Z-score, which was then adjusted by age and sex.RESULTS:
The prevalence of caries was 79.9% (DMFT≥1) in permanent dentition. Of all children, 47.5% of them brushed their teeth two or more times per day, and the prevalence of overweight and obesity was 20.1% and 17.6%, respectively. The logistic regression model showed that children with obesity (a >2 Z-score on the BMI-for-age growth chart) were less likely to have dental caries (odds ratio [OR] = 0.53 [95% confidence interval {CI} 0.31-0.89]; P = 0.017) than children without obesity, with schoolchildren who consume more sweets per day (OR = 1.65 [95% CI 1.03-2.62]; P = 0.035) more likely to present caries than schoolchildren who consume fewer sweets per day.CONCLUSION:
Children with obesity are less likely to present dental caries. Comprehensive strategies aimed at risk factors can be useful in controlling nutritional status and improving oral health.Palavras-chave
