  1. Fulltext. Passive and active maternal smoking as measured by serum cotinine : the effect on birthweight.

    Article - En anglais


    To determine how maternal exposure to environmental tobacco smoke affects birthweight, maternal sera obtained from 3529 pregnant women around 27 weeks gestation were analyzed for cotinine, a metabolite of nicotine.

    Based on cotinine levels, nonsmokers were divided into those exposed to environmental tobacco smoke (2-10 ng/mL) and those unexposed (<2 ng/mL), and smokers were divided into tertiles.

    Compared with unexposed nonsmokers'infants, infants of exposed nonsmokers averaged 45 g less (P=28) after adjustment for confounders, and smokers'infants averaged 78,191, and 233 g less for the first, second, and third cotinine tertiles, respectively.

    Birthweight decreased 1 g for every nanogram per milliliter of cotinine increase (P<. 001).
