    Author: Jeppesen DL, Nielsen SD, Ersbøll AK, Valerius NH.
    Journal: Neonatology; 2008; 94(2):75-8. PubMed ID: 18212492.
    Abstract:
    BACKGROUND: Maternal smoking during pregnancy is known to be associated with perinatal complications such as preterm delivery, low birth weight, and sudden infant death syndrome. OBJECTIVE: The purpose of this study was to evaluate the influence of smoking during pregnancy on the risk of postnatal infections in preterm neonates. METHOD: We examined 80 preterm infants (gestational age 24-36 weeks), of whom 40% had been exposed to tobacco smoking during pregnancy. RESULTS: Infections occurred in 31 infants. Gestational age and maternal smoking had a significant effect on the occurrence of infections (p < 0.001 and p = 0.015, respectively). An increase in maternal tobacco consumption by 10 cigarettes/day showed an odds ratio of 2.7 (95% confidence interval 1.1-6.4) for occurrence of infections. CONCLUSIONS: A significant association between maternal use of tobacco and the occurrence of infections in preterm neonates was found. Thus, campaigns about the damaging effects of tobacco are still warranted.
