Prenatal Exposure to Cigarettes in Infants With Obstructive Sleep Apneas

Abstract

Prenatal smoking by mothers correlated with an increase in frequency and length of obstructive apneas and a decrease in birth weight of their infants. The infants were under greater risk for obstructive apnea if both parents smoked. Explanations for our results are unknown to us, but these findings may be of interest in the study of infant breathing behavior and epidemiological characteristics of sudden infant death syndrome.
