[en] Aims : Understanding the differences in reproductive-health behaviours between native and migrant populations helps provide good reproductive-health services. We investigate the differences in induced abortion rates, pregnancy histories and use of contraceptives between native and migrant populations in Finland. Methods : The Finnish Register on Induced Abortions was linked with Population Register data from years 2001–2014 to identify first- and second-generation immigrants. The data included 142,708 induced abortions. Results : Abortion and contraceptive use varied between women of Finnish and foreign origins. Native women had a lower abortion rate than women born abroad. Women born in Somalia and India had the highest likelihood for having an abortion shortly after birth. The highest risk for having an abortion soon after previous induced abortion was among women born in Iran, Iraq, Somalia and former Yugoslavia. The risk for having more than two induced abortions was the highest for women born in Russia/the former Soviet Union and Estonia. Second-generation immigrants had a lower abortion rate than first-generation immigrants. Lack of contraceptive use prior to abortion was more common among women born abroad. Conclusion : There were differences in pregnancy histories and in the use of reliable contraceptive methods before an induced abortion by country of birth. The higher likelihood for abortion after a recent birth among first-generation immigrants highlights the need for more targeted counselling immediately after childbirth. Although the abortion rate is lower among second-generation immigrants, the neglect of contraceptive use calls for additional education in sexual and reproductive health.
