Caroline Moreau et al., Previous Induced Abortions and the Risk of Very Preterm Delivery: Results of the EPIPAGE Study, 112 INT'L J OBSTETRICS & GYNAECOLOGY 430 (2005).

The objective was to evaluate the risk of very preterm birth (22-32 weeks of gestation) associated with previous induced abortion according to complications leading to very preterm delivery in singletons. This was a multicenter, case-control study (EPIPAGE) of a regionally defined population of births in France. The sample consisted of 1943 very perterm live-born singletons (

Data from the EPIPAGE study were analyzed using polytomous logistic regression models to control for social and demographic characteristics, lifestyle habits during pregnancy and obstetric history. The main mechanisms of preterm delivery were classified as gestational hypertension, antepartum hemorrhage, fetal growth restriction, premature rupture of membranes, idiopathic preterm labor and other causes. Main outcome measures were odds ratios for very preterm birth by gestational age and by pregnancy complications leading to preterm delivery associated with a history of...
