Abstract
OBJECTIVES: We evaluated late pregnancy abortions from 1981 to 2006 in Québec, Canada. METHODS: We extracted late abortions from the stillbirth mortality file, and calculated yearly rates per 100,000 pregnancies, including mean gestational age, birth weight, maternal age and education. RESULTS: There were 14.4 late abortions per 100,000 overall pregnancies [95% confidence interval 12.9, 16.1], and rates appeared to increase with time. Mean gestational age (24.7 weeks) and birth weight (886 g) suggested that abortions were performed in the late second and third trimesters. CONCLUSIONS: Late abortions in Québec are not common but do occur. Research is needed to determine whether the increase in rates over time reflects better reporting or a true increase. Improved surveillance of late abortions may be warranted.
