Prenatal life events stress: implications for preterm birth and infant birthweight
Abstract
Objective The objective of the study was to evaluate the effects of maternal exposure to severe life events during different stage of gestation on preterm birth and infant birthweight.Study design A sample of 1800 women who delivered after 32 weeks' gestation were assessed with questionnaires that measured stressful life events during different stages of pregnancy. Demographic characteristics and birth outcomes were collected through the interviews and medical charts.Results There was an increased risk of preterm birth among women with higher levels of life events stress during the first trimester (adjusted risk ratio, 2.40; 95% confidence interval, 1.13-5.09) and second trimester (adjusted risk ratio, 2.86; 95% confidence interval, 1.26-6.47). Each unit increase of perceived life events stress during first trimester was associated with a 99.09 g decrease in infant birthweight.Conclusion Prenatal severe life events, especially in the first trimester, may play an important role in increasing the risk of preterm birth and low birthweight.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
