Objective: To estimate the incidence of excess of body weight in the school period and explore possible association with prenatal factors. Methodology: An epidemiological study with a longitudinal design was carried out. All children from the first to the fifth grade of elementary school, aged between seven and 10 years old, enrolled in public and private schools and from families residing in Palhoça City, Santa Catarina State, who had participated in the previous stage of the study in 2015, were included. To obtain the BMI, weight and height were collected in schools. Data related to the prenatal period were obtained with interviews with mothers or guardians, at home. The analyses were performed using Poisson Regression with a robust estimator. Statistically significant variables and those with p ≤ 0.25 in the bivariate analysis were included in the multivariate. Results: 228 students were included. The incidence rate of excess weight was 19.3%, with 17.1% being overweight and 2.2% being obese. The results of the multivariate analysis showed that students who were born with Apgar in the first minute ≤ 7 had a statistically significant risk and 34% higher relative risk of developing excess weight in the school period. Conclusion: The incidence of overweight was 19.3%. Prenatal factors were not associated with incidence, except for a low Apgar score in the first minute.
Objetivo: Estimar a incidência de excesso de peso corporal no período escolar e a associação com fatores pré-natais. Métodos: Estudo epidemiológico de delineamento longitudinal. Incluídas crianças com 10 anos matriculadas em escolas públicas e privadas e de famílias residentes em Palhoça/SC participantes da pesquisa em 2015. Para o índice de massa corporal, coletaram-se peso e estatura. Dados do período pré-natal foram obtidos em entrevistas com as mães ou responsáveis. As análises ocorreram por regressão de Poisson com estimador robusto. As variáveis estatisticamente significativas e aquelas com p ≤ 0,25 na análise bivariada foram incluídas na multivariada. Resultados: Foram incluídos 228 escolares. A taxa de incidência de excesso de peso foi de 19,3% — 17,1% de sobrepeso e 2,2% de obesidade. Os resultados da análise multivariada mostraram que escolares que nasceram com Apgar no primeiro minuto ≤ 7 apresentaram risco relativo estatisticamente significativo e independente 34% maior de desenvolver excesso de peso no período escolar. Conclusão: A incidência de excesso de peso foi de 19,3%. Fatores pré-natais não se mostraram associados à incidência, com exceção de baixo Apgar no primeiro minuto.
