Background A possible association between being overweight or obese and early childhood caries (ECC) remains controversial. Aim To investigated this association in a developing country testing the confounding effects of socioeconomic factors and frequency of sugar consumption. Methods Historical cohort study, 388 children (aged 24–71 months) living in São Luís, Brazil. A theoretical model adjusted according to income, birthweight, and nutritional status at twelve months and frequency of sugar consumption was generated with directed acyclic graphs to analyze this association. Caries were considered a discrete variable in the Poisson regression models; incidence density ratios (IRs) and 95% confidence intervals (95% CIs) were estimated. Results Being overweight or obese (IR = 1.52; 95% CI: 1.03–2.22) was independently associated with ECC. Being thin or very thin (IR = 1.97; 95% CI: 1.52–2.54), a high frequency of sugar consumption (IR = 1.83; 95% CI: 1.42–2.38), and age (IR = 3.62; 95% CI: 2.58–5.08) were associated with ECC. Conclusions Children overweight or obese, as well as children exhibiting being thin/very thin, were associated with ECC independent of socioeconomic variables and a high frequency of sugar consumption.
