Childhood predictors of becoming a teenage mother among Finnish girls

OBJECTIVE: To study predictive associations between psychosocial factors at age 8 and becoming a mother under the age of 20. DESIGN: Prospective follow-up study. SETTING: Finland. POPULATION: 2867 girls born in 1981. METHODS: Information on family background and psychiatric symptoms was collected at age 8. The associations between these factors and becoming a teenage mother were analyzed using logistic regression analysis. MAIN OUTCOME MEASURES: Data on births by the age of 20 collected from the hospital discharge register. RESULTS: 128 girls (4.8%) had given birth at the age of 15-19 years. Childhood conduct problems and hyperactive problems, having young mother and family structure other than two biological parents had an independent association with becoming a teenage mother. CONCLUSIONS: Girls with externalizing type of problems in childhood have an increased risk of becoming teenage mothers. These problems may also complicate their motherhood.
