  1. Fulltext. Does passive smoking in early pregnancy increase the risk of small-for-gestational-age infants ?

    Article - En anglais

    Fulltext.

    Objectives

    This study tested the hypothesis that women who deliver small-for-gestational-age infants are more often exposed to passive smoking at home or at work.

    Methods

    Among a 1-year cohort of nulliparous women in the city of Malmö, Sweden, 872 (87.7%) women completed a questionnaire during their first prenatal visit.

    The study was carried out among women whose pregnancies resulted in a singleton live birth (n=826) ; 6.7% of infants were classified as small for their gestational age.

    Results

    Passive smoking in early pregnancy was shown to double a woman's risk of delivering a small-for-gestational-age infant, independent of potential confounding factors such as age, height, weight, nationality, educational level, and the mother's own active smoking (odds ratio [OR]=2.7).

    A stratified analysis indicated interactional effects of maternal smoking and passive smoking on relative small-for-gestational-age risk.

    Conclusions

    Based on an attributable risk estimate, a considerable reduction in the incidence of small-for-gestational-age births could be reached if pregnant women were not exposed to passive smoking.
