Demographic characteristics in adult paternity for first births to adolescents under 15 years of age.

PURPOSE

To examine parental demographic characteristics by adult (> or = 20 years at baby's conception) and teenage (< 20 years at baby's conception) paternity in births to very young adolescents (< 15 years at baby's conception).

METHODS

This was a population-based, retrospective cohort analysis of all 12,317 very young adolescent mothers residing in California with a first singleton live birth during 1993-1995. Risks for adult, compared to teenage, paternity were evaluated using multivariate logistic regression.

RESULTS

Adult fathers, responsible for 26.7% of births to very young adolescents, were a mean of 8.8 years older than the mother. The risk factors for adult compared to adolescent paternity were as follows: father's educational attainment of at least 3 years below that considered adequate for his age [adjusted odds ratio (AOR) = 8.34], father's (AOR = 2.46) or mother's (AOR = 1.36) educational attainment 1-2 years below that considered adequate for their age, mother's birthplace outside the United States (AOR = 3.12), and father's Hispanic ethnicity (AOR = 1.60) or African-American race (AOR = 1.50).

CONCLUSIONS

Adult fathers were responsible for over one quarter of the births in our study. Adolescent pregnancy prevention focusing on younger adolescents must programmatically address adult paternity. Variations in adult paternity patterns across cultural groups suggest that we need further study of the role that cultural beliefs and practices play in very young adolescent pregnancy.
