Reproductive mortality and its relation to different methods of birth control.

This report evaluates the decrease in maternal mortality and its relation to family planning methods in Sweden during the years 1911-80. In the 1930s fertility was low but illegal abortions were at a high level and the associated maternal death rate was 18.5 per 1000 women. With the legalization of abortion and the introduction of modern contraceptive methods, the crude reproductive mortality rate in 1965-70 was 1.7 per 100,000 women and this was reduced still further, especially for younger women, by the late 1970s. Standardized reproductive mortality was then 80% higher than the crude rate, indicating the importance of modern family planning methods. Mortality associated with oral contraceptive or IUD use in Sweden during the 1960s and 1970s was lower than in England and the US. Mortality associated with sterilization was 6.2 per 100,000 procedures.
