SUMMARY:

"Background: Obesity and dental caries are two of the most common conditions affecting children and both have significant implications on their wellbeing and future health. Even though research into the relationship between the two conditions has been conducted for many years, results to date remain equivocal. Aim: The current study aimed to to evaluate the relationship between obesity and dental caries in Brazilian children aged 6 to 9 years and American children and adolescents aged 2 to 5 years and 8 to 19 years, as well as to investigate possible individual and environmental determinants associated with both conditions. Methods: The study was divided into three parts: data analysis (dental caries, body mass index (BMI), BMI z-score (ZBMI) and waist-to-hip ratio (WHR)) from the Estrutural Affordable Health Initiative (AHI) project in schoolchildren aged 6 to 9 years living in a highly deprived community in the Federal District, Brazil; data analysis (dental caries, BMI, ZBMI) of children aged 2 to 5 years from the National Health and Nutrition Examination Survey (NHANES) 2011–2018 in the United States; and data analysis (dental caries, fat mass index (FMI) and fat percentage (BF%)) of children and adolescents aged 8 to 19 years also from NHANES 2011-2018. Associations were tested in regression models adjusted for confounding factors. Results: In regard to the AHI data, 62% of the children had caries experience according to the World Health Organization (WHO) criteria and 34% had unhealthy body weight according to the International Obesity Task Force (IOTF) reference. ROC (Receiver Operating Characteristic) analysis showed that BMI (AUC 0.492, 95% CI: 0.439 to 0.545) and WHR (AUC 0.514, 95% CI: 0.461 to 0.567) were weak predictors of dental caries. Regarding NHANES data from children aged 2 to 5 years, in crude models, obesity was associated with greater dt scores when using the IOTF standards (RR: 2.43, 95% CI: 1.11, 5.29), but not when using the WHO and the Centers for Disease Control and Prevention (CDC) standards; obesity was associated with greater dft scores when using the WHO (1.57, 95%CI: 1.11–2.22), CDC (1.70, 95%CI: 1.17–2.46) and IOTF standards (2.43, 95%CI: 1.73–3.42); obesity was associated with lifetime caries prevalence when using the WHO (1.55, 95%CI: 1.05–2.29), CDC (1.73, 95%CI: 1.14–2.62) and IOTF standards (2.45, 95%CI: 1.61–3.71), but not with untreated caries prevalence. These associations were fully attenuated after controlling for demographic factors, family SES and child’s intake of added sugars. In children and adolescents aged 8 to 19 years, FMI score was associated with the DMFT score (rate ratio: 1.03, 95%CI: 1.01-1.05) and lifetime caries prevalence (odds ratio: 1.06, 95%CI: 1.03-1.08), but the associations were attenuated after adjustment for confounders. Neither the BF% score nor the presence of excess adiposity, defined according to the BF% or FMI reference standards, were associated with dental caries. Conclusions: It was concluded that the relationship between obesity and caries in children and adolescents varied according to the measures of adiposity adopted, as well as the definition of obesity and dental caries used. Furthermore, the associations were fully attenuated after adjustment for household socioeconomic status and child added sugars intake."
