Despite long-standing public support for sex education in the schools,
it has been difficult to show concrete effects of sex education on se
xual and contraceptive behavior. Data from the 1988 National Survey of
Family Growth indicate that exposure to a formal contraceptive educat
ion program increases the likelihood that a teenage woman will use a c
ontraceptive method at first intercourse. According to the results of
a multivariate analysis, the odds that a young woman will use any meth
od and the odds that she will use a condom increase by about one-third
following instruction about birth control; the effect on the likeliho
od of pill use, however, is nonsignificant. If contraceptive education
occurs in the same year that a teenager becomes sexually active, the
odds of any method use and of condom use are increased by 70-80%, and
the odds of pill use are more than doubled. The results also suggest t
hat with greater educational efforts, the proportion of teenagers who
use condoms at first intercourse could increase from 52% to 59%, while
the proportion using no method might decrease from 41% to 33%.
