Factors associated with early sexual activity among urban adolescents.

This study uses lifespan and ecological frameworks to investigate the factors associated with early adolescent sexual activity. Data from a longitudinal study of urban teenagers of color address three issues: (1) the prevalence and pattern of sexual activity among boys and girls ages 15 and younger, (2) the link between early sexual activity and high-risk sexual behavior, and (3) the life contexts linked with early sexual activity. Results from 803 African American and Hispanic adolescents suggest a high prevalence of early sexual activity, which is associated with higher rates of childbearing and risky sexual behavior than sexual activity initiated in later adolescence. Somewhat different factors are associated with early sexual activity for boys and girls, although family composition, parent attachment, and substance use are important for both genders. Implications for intervention are discussed.
