Teen sex not always bad for school performance

There's good news for parents who worry that their teenagers' sex lives are affecting their school performance: A provocative new study has found that teens in committed relationships do no better or worse in school than those who don't have sex.

The findings, presented Sunday at a meeting of the American Sociological Association in Atlanta, challenge to some extent assumptions that sexually active teens tend to do poorer in school.

—Teens in serious relationships did not differ from their abstinent counterparts in terms of their grade-point average, how attached they are to school or college expectations. They were also not more likely to have problems in school, be suspended or absent.
