[Epidemiology of induced abortion in France].

OBJECTIVES: Conduct a synthesis of existing knowledge about the frequency of induced abortion or termination of pregnancy and unplanned pregnancies, the exposure factors of unplanned pregnancies and abortion and the associated morbidity and mortality.

METHODS: Consultation of The Medline database, and national and international reports on abortions in France and in developed countries.

RESULTS: Voluntary termination of pregnancy is an induced abortion, opted for non-medical reasons, which in France can be performed before 14 weeks of gestation. Abortion is a common procedure, with rare complications, amounting to about 220,000 procedures per year in France with a stable rate over decades. Similarly to births, women aged 20 to 24 are most affected. The possibility of an abortion exists for all women; this potential event, however, is not equal for each and varies by age of women, socio-professional situations, geographical origins, marital status and past or present domestic and sexual violence. The French historical analysis shows that for 50 years the increase in contraceptive prevalence rate is associated with a decrease in the frequency of unplanned pregnancies. It is therefore possible that the prevention of unplanned pregnancy through early uptake of contraception and contraception options by women is related to a woman's lifestyle. Nonetheless, the number of abortion remains stable since its decriminalization despite the large increase in medicalized contraceptive prevalence rate.

CONCLUSION: Good knowledge of the epidemiology of voluntary termination of pregnancy and unplanned pregnancies is a prerequisite to better adopt prevention and case management strategies.
