  1. Maternal work during pregnancy and the risks of delivering a small-for-gestational-age or preterm infant.

    Article - En anglais

    Objective The objective of this study was to assess the relation of some maternal job characteristics to the risks of delivering a small-for-gestational-age or preterm infant.

    Methods Altogether 4390 women who lived in Quebec City, Canada, and the surrounding area, and who gave birth between January and October 1989 to a singleton liveborn neonate were included.

    Information on gestational age at delivery, job characteristics, nonoccupational physical activities, and several potential confounders was obtained in a telephone interview a few weeks after the delivery.

    Birthweight was recorded from the birth certificate.

    Results The risk of having a small-for-gestational-age infant (birthweight lower than the 10th percentile for gestational age and gender) was increased among the women who worked at least 6 h a day in a standing position.

    The adjusted odds ratios (OR) were 1.00,1.13 [95% confidence interval (95% CI) 0.83-1.55], and 1.42 (95% CI 1.02-1.95) for the women working in a standing position<3,3-5, and = 6 h a day, respectively.

    The risk for a small-for-gestational-age infant also slightly increased as the gestational age at work cessation increased.

    A modest increment in the risk of delivering preterm (OR 1.45,95% CI 0.8-2.49) was observed for the women working regularly in the evening or at night.

    Physical effort, lifting heavy objects, and long workhours were not related to either a small-for-gestational-age or a preterm infant.
