ABSTRACT

This study assessed the effect of maternal tobacco smoking during pregnancy on their infants' respiratory health during the first year of life in a random sample of 184 mother-infant binomials. Data were analyzed using chi square test for proportions and multivariate logistic regression adjusting for covariates. Infants exposed to maternal smoking during pregnancy had a significantly higher risk of suffering from wheezing (p < 0.01), acute respiratory illnesses (p < 0.01) and admissions due to pneumonia (p < 0.05) during their first year of life than non-exposed infants. Accordingly to what has been described in developed countries, in this sample from a low socioeconomic status population, active maternal tobacco smoking during pregnancy significantly increased infants' susceptibility for suffering from wheezing, acute respiratory illnesses and hospital admissions due to pneumonia during the first year of life.


Este estudio evaluó el efecto del tabaquismo materno durante el embarazo sobre la salud respiratoria de sus lactantes durante el primer año de vida, en 184 binomios madre-hijo. El análisis se realizó mediante chi cuadrado para proporciones y regresión logística multivariada ajustando para covariables. Los hijos de madres que fumaron durante el embarazo tuvieron un riesgo significativamente mayor de sufrir de bronquitis obstructiva (p < 0,01), de enfermedades respiratorias agudas en general (p < 0,01) y de hospitalización por neumonía (p < 0,05), en comparación con los hijos de madres que no fumaron durante el embarazo. Concordantemente con lo descrito en países desarrollados, en esta muestra proveniente de una población de bajos recursos socioeconómicos, el tabaquismo materno durante el embarazo aumentó significativamente la susceptibilidad de los lactantes para sufrir de bronquitis obstructivas, enfermedades respiratorias agudas y de hospitalizaciones por neumonía en su primer año de vida.
