Today the CDC released a report on the effectiveness of various approaches to teen pregnancy and HIV/STI prevention. The study was conducted by the Task Force on Community Preventative Services, an independent panel convened by the CDC. The report suggests that such prevention programs are most effective when they combine a clear message on the benefits of postponing sexual activity with medically accurate and comprehensive information on how to reduce the risks of pregnancy and STIs among teens who are having sex--including the use of contraception.

Most of the American public gets this. It's common sense. Yet, today's results are debated by many, with some saying they prove comprehensive sex ed programs work and abstinence education programs don't, and some saying the reverse. This debate arises in part because comprehensive sex ed and abstinence-only actually encompass many, many different programs, with varying levels of effectiveness behind them. The debate is fueled as much by ideology as it is by science and will likely continue for some time to come.

For those practitioners, educators and parents looking for a common-sense way forward in the meantime, I suggest focusing on specific programs rather than programmatic approaches. Some, but not all, comprehensive programs have rigorous evidence of positive impacts. These have been well-summarized. To date, none of the abstinence-only curricula have this level of evidence behind them, although that is not to say there may not be some in the future.

Efforts have their best chance of success if they stay grounded in science, whatever the state of the science is at the time. It's also important to realize that, while the reproductive health education we provide our teens in school is critical, no curriculum, regardless of its underlying ideology, is a silver bullet. Communities that truly care about preventing teen pregnancy need a comprehensive approach that includes not only schools, but also parents, community leaders, the media, and teens themselves.
