  Background and aim: The cesarean births have increased, just like observed for obesity and overweight in childhood. This study aims to report the association between cesarean birth and the nutritional development status of 6/7-year-old. Materials and methods: As part of the Coorte Brasil Sul, the study involved 475 randomly selected children from the city of Palhoça, Brazil, born in 2009. Demographic, pregnancy and birth characteristics and children nutritional status were obtained. Measures of weight and height were converted to age and sex-adjusted z-scores of height-for-age (HFAz), weight-for-age (WFAz) and BMI-for-age (BMIz). Results: Among these children, 196 (41.3%) were born by cesarean section and 279 (58.7%) were born by vaginal birth. No differences were found between the means of the BMIz, WFAz and HFAz according to the mode of delivery, as well as the average treatment effect. Conclusion: Cesarean birth was not associated with the nutritional development status of 6/7-year-old in the studied population.

  Introdução e objetivo: A incidência de cesariana tem aumentado, bem como o observado para a obesidade e o sobrepeso na infância. Este estudo tem como objetivo reportar a possível associação entre o parto ocorrido por cesariana e o status de desenvolvimento nutricional aos 6/7 anos de idade. Materials e métodos: Como parte da Coorte Brasil Sul, o estudo envolveu 475 crianças selecionadas randomicamente na cidade de Palhoça, Brasil, nascidas em 2009. Foram identificadas as características demográficas, gestacionais e relativas ao nascimento, bem como o status no desenvilmento nutricionais destas crianças. Foram realizadas as aferições de peso e altura e convertidos para os escores Z ajustados por idade e sexo para altura-por-idade (HFAz), peso-por-idade (WFAz) e IMC-por-idade (BMIz). Resultados: Entre estas crianças, 196 (41,3%) foram nascidas por cesariana e 279 (58,7%) por parto vaginal. Não foram identificadas diferenças entre as medias de BMIz, WFAz e HFAz ajustados pela via de parto, bem como quando realizado o efeito médio de tratamento dos dados. Conclusão: O nascimento por cesariana não esteve associado ao desenvolvimento nutricional aos 6/7 de idade na população estudada. ABSTRACTCesarean birth and the nutritional development in childhood: results from a cohort in Southern BrazilBackground and aim: The cesarean births have increased, just like observed for obesity and overweight in childhood.
