  1. Fulltext. Maternal cigarette smoking during pregnancy and risk of oral clefts in newborns.

    Article - En anglais


    The results of previous epidemiologic research on the possible association between maternal smoking during pregnancy and risk of oral clefts in offspring have been inconsistent.

    This may be due in part to methodological limitations, including imprecise measurement of tobacco use, failure to consider etiologic heterogeneity among types of oral clefts, and confounding.

    This analysis, based on a large case-control study, further evaluated the effect of first trimester maternal smoking on oral facial cleft risk by examining the dose-response relationship according to specific cleft type and according to whether or not additional malformations were present.

    A number of factors, including dietary and supplemental folate intake and family history of clefts, were evaluated as potential confounders and effect modifiers.

    Data on 3,774 mothers interviewed between 1976 and 1992 by the Slone Epidemiology Unit Birth Defects Study were used.

    Study subjects were actively ascertained from sites in areas around Boston, Massachusetts and Philadelphia, Pennsylvania ; the state of Iowa ; and southeastern Ontario, Canada.

    Cases were infants with isolated defects-cleft lip alone (n=334), cleft lip and palate (n=494), or cleft palate alone (n=244) - and infants with clefts plus (+) additional malformations : cleft Ilp+ (n=58), cleft lip and palate+ (n=140), or cleft palate+ (n=209). (...)
