Conduct disorder symptoms and subsequent pregnancy, child-birth and abortion: a population-based longitudinal study of adolescents.

摘要

Research on teenage pregnancy and abortion has primarily focused on socio-economic disadvantage. However, a few studies suggest that risk of unwanted pregnancy is related to conduct disorder symptoms. We examined the relationship between level of conduct disorder symptoms at age 15 and subsequent pregnancy, child-birth and abortion. A population-based, representative sample of Norwegian adolescent girls (N = 769) was followed from early adolescence until their mid-20s. Even with control for socio-demographic and family variables, conduct disorder symptoms at age 15 were strongly associated with pregnancy in the 15-19 age group, and a weaker association persisted in the 20-28 age group. Similar results were obtained for abortions, but here a strong relationship with conduct disorder symptoms was found even after age 20. After adjustment, no significant association between conduct disorder symptoms and subsequent child-birth was observed. More targeted preventive programmes aimed at girls with conduct disorder symptoms may be warranted.
