Late pregnancy abortions: An analysis of Québec stillbirth data, 1981-2006

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. © Swiss School of Public Health 2011.
