Teenage pregnancies and abortions in Finland in the 1990s.

AIMS

This study analyses trends and regional variation in teenage pregnancy, abortion, and fertility rates in Finland in the 1990s, by single-year age group.

METHODS

Individual-level data from Finnish abortion and birth registers maintained by the National Research and Development Centre for Welfare and Health (STAKES) were used to calculate the rates and the abortion ratio. The abortion ratio was also calculated using conception as the time reference.

RESULTS

Teenage pregnancy rates and abortion rates reverted from decrease to increase in the mid-1990s. This was accompanied by an increase in the share of teenage pregnancies that ended in an abortion. The increase in abortions started first among older teenagers, and spread gradually to younger girls. Regional variation in the rates remained the same throughout the study period.

CONCLUSIONS

The observed trends reflect a change towards less effective use of contraceptive methods among teenagers. There is also evidence of the earlier start of teenage sexual activity at the end of the 1990s. The possible explanations for less effective contraceptive use include cutbacks in healthcare and family planning services in the first half of the 1990s and the reduction of sex education in schools.
