ABSTRACT
ABSTRACT Objective: To investigate the possible relationship between early admission to the school of children in early childhood and oral health conditions (OH) and nutritional status (NS). Material and Methods: Cross-sectional study conducted with 140 children aged 3-4 years, selected for convenience, in 4 public schools in the city of São Paulo, Brazil, during 2016, divided into children with early (IE) and late (IL) admission at school. Comparisons between groups were performed for the presence of overweight / obesity (OW / OB), caries lesions (CL), malocclusion (MO) and dental biofilm (DB), in addition to socioeconomic and dietary data. Multiple regression analysis was applied to determine the association between age of admission at school and OH and NS. Results: Children with IE had CL = 28.1%; DB = 46.9%; MO = 54.7% and OW / OB = 25.9%. Children with IE had IL = 29.8%; DB = 35.1%; MO = 61.4% and OW / OB = 30.8%. No significant association was found between age of admission at school and CL: 1.40 (0.53-3.73) 0.490; DB: 0.51 (0.22-1.16) 0.112; MO: 1.77 (0.77-4.05) 0.173 and OW / OB: 1.27 (0.55-2.92) 0.568, [OR (95% CI) p]. Conclusion: The age of admission at school of children in early childhood did not show a significant association with OH and NS.
