Associação entre sobrepeso/obesidade e cárie dentária em crianças/adolescentes brasileiros: uma revisão sistemática e meta-análise

Abstract

This systematic review with meta-analysis evaluated the association between overweight and/or obesity and dental caries in Brazilian children/adolescents. Searches were performed in the Web of Science, Scopus, Cochrane, PubMed, SciELO, Lilacs and grey literature databases until January 2022. The risk of bias was assessed using the Joanna Briggs Institute scales. A total of 41 publications were included and 13 meta-analyses were performed. We analyzed the differences in weighted means (MD) and odds ratios and their corresponding confidence intervals (CI) (95%) for dental caries among eutrophic and obese and/or overweight children/adolescents. There was no association between normal weight and obese and/or overweight children/adolescents in relation to dental caries for primary and permanent teeth for any meta-analysis, except the one that included studies with adolescents in permanent dentition and classified obesity with body mass index (BMI) based on the CDC (2000) anthropometric reference curve. This meta-analysis showed that obese adolescents had a lower mean of dental caries compared to normal-weight adolescents (MD=0.61; 95% CI=0.08-1.15). It was concluded that there is no association between overweight/obesity and dental caries in Brazilian children/adolescents for most anthropometric reference curves using BMI. The strength of the evidence of the results was considered very low, low and moderate.
