Jalanko E, et al. - Finnish healthcare registers to assess the risk of psychiatric morbidity after teenage induced abortion (n = 6,520) or childbirth (n = 6,806) was used using Poisson regression analysis in order to investigate the relationship between adolescent pregnancy and psychiatric morbidity according to pregnancy outcome (induced abortion vs childbirth) and age (< 20 or < 18 years) at the beginning of a pregnancy. In the teenage abortion group vs those without a teenage pregnancy, the risk of psychiatric morbidity was higher, however, this risk rose only at 5 years postabortion. Between the teenage pregnancy groups aged < 20 years (induced abortion vs childbirth), no variation in psychiatric morbidity was discovered. Nonetheless, women who underwent an abortion at < 18 years of age instead of childbirth had to face a lower risk of psychiatric morbidity, especially during the first 5 years postabortion. In conclusion, irrespective of the outcome (induced abortion or childbirth) of the pregnancy, pregnant adolescents had to face an enhanced risk of psychiatric morbidity in adulthood. Among girls aged < 18 years, the risk of mental disorders, in comparison with childbirth, was lower following the abortion. Hence, when counseling pregnant adolescents and organizing family planning services for teenagers, this finding should be taken into consideration.
