PurposeSex education is intended to provide youth with the information and skills needed to make healthy and informed decisions about sex. This study examined whether exposure to formal sex education is associated with three sexual behaviors: ever had sexual intercourse, age at first episode of sexual intercourse, and use of birth control at first intercourse.MethodsData used were from the 2002 National Survey of Family Growth, a nationally representative survey. The sample included 2019 never-married males and females aged 15-19 years. Bivariate and multivariate analyses were conducted using SUDAAN. Interactions among subgroups were also explored.ResultsReceiving sex education was associated with not having had sexual intercourse among males (OR = .42, 95% CI = .25-.69) and postponing sexual intercourse until age 15 among both females (OR = .41, 95% CI = .21-.77) and males (OR = .29, 95% CI = .17-.48). Males attending school who had received sex education were also more likely to use birth control the first time they had sexual intercourse (OR = 2.77, 95% CI = 1.13-6.81); however, no associations were found among females between receipt of sex education and birth control use. These patterns varied among sociodemographic subgroups.ConclusionsFormal sex education may effectively reduce adolescent sexual risk behaviors when provided before sexual initiation. Sex education was found to be particularly important for subgroups that are traditionally at high risk for early initiation of sex and for contracting sexually transmitted diseases.
