Abstract Objectives: to estimate the role of maternal overweight and obesity before pregnancy as predictors of childhood asthma in a population of Peruvian children under five years. Methods: we carried out a retrospective cohort study of children aged five years or less and their mothers from the Regional Hospital of Ayacucho and the María Auxiliadora Hospital in Lima, Peru. We included children who were born between 2013 and 2014 and follow them up until 2018 and 2019, respectively. The diagnosis of overweight and obesity of the mother before pregnancy and asthma in the child were registered in their clinical histories. Crude (cRR) and adjusted relative risks (aRR) and 95% confidence intervals (CI95%) were obtained using a generalized lineal model of the Poisson family with link log and robust variances. Results: we evaluated 431 medical records and found that 20.9% of the children had asthma, 26.7% of the mothers were overweight, and 20.2% were obese before pregnancy. In the adjusted regression model, overweight (aRR=2.94; CI95%= 1.54-5.60) and maternal obesity (aRR=5.10; CI95%= 2.73-9.51) were predictors of an increased risk of childhood asthma. Conclusions: maternal overweight and maternal obesity increased the risk of her children developing asthma threeand five-fold, respectively.

Resumen Objetivos: estimar el papel del sobrepeso y la obesidad materna antes del embarazo como predictores de asma infantil en una población de niños peruanos menores de cinco años. Métodos: realizamos un estudio de cohorte retrospectivo de niños de cinco años o menos y sus madres del Hospital Regional de Ayacucho y del Hospital María Auxiliadora de Lima, Perú. Se incluyeron niños nacidos entre 2013 y 2014 y se les dio seguimiento hasta 2018 y 2019, respectivamente. El diagnóstico de sobrepeso y obesidad de la madre antes del embarazo y asma en el niño fueron registrados en sus historias clínicas. Los riesgos relativos crudos (cRR) y ajustados (RRa) y los intervalos de confianza del 95% (IC95%) se obtuvieron mediante un modelo lineal generalizado de la familia de Poisson con log de enlace y varianzas robustas. Resultados: se evaluaron 431 historias clínicas y se encontró que el 20,9% de los niños tenían asma, el 26,7% de las madres tenían sobrepeso y el 20,2% eran obesas antes del embarazo. En el modelo de regresión ajustada, el sobrepeso (aRR=2,94; IC95%= 1,54-5,60) y obesidad materna (RRa=5,10; IC95%= 2,73-9,51) fueron predictores de un mayor riesgo de asma infantil. Conclusiones: el sobrepeso materno y la obesidad materna aumentaron tres y cinco veces el riesgo de que sus hijos desarrollaran asma, respectivamente.
