Adolescent reproductive attitudes and knowledge effects on early adult unintended and nonmarital fertility across gender.

Theory and evidence suggest strong short-term effects of attitudes toward, and knowledge about, reproduction on women's fertility. Adolescent attitudes and knowledge may also have longer-term implications about the contexts women perceive as appropriate for childbearing and their capacity to manage their preferences. Although previous research on men's fertility is limited, theory would suggest the links between adolescent attitudes and knowledge and subsequent fertility would also exist for men (though perhaps in different ways given the gendered meanings of sex, contraception, and reproduction). We analyze the relationship between reproductive attitudes and knowledge in adolescence and unintended and nonmarital first and second births in early adulthood, using the National Longitudinal Study of Adolescent to Adult Health (N = 9,431). Adolescent reproductive attitudes, especially life course consequences of early childbearing, predict the intendedness and marital status of first and second births. Adolescent reproductive knowledge is more often linked to the context of second births than first births. These associations vary by gender, but the overall results suggest that fertility schemas developed during adolescence predict behavior into early adulthood.
