It's not every day that you come across something online that you think is truly different, useful and, even fun. The other day I came across a website, "Maria Talks," that I think meets this criteria. The site was created through funding from the Massachusetts government, and it operates in conjunction with the Massachusetts Sexual Health Hotline. As someone who has spent plenty of time searching the web for resources on sexual health and birth control, I think that this site stands out.

At The National Campaign, we often send the message that safe sexual practices among teens are best achieved through ongoing conversation and communication. First and foremost, teens themselves have told us their parents most influence their decisions about sex, and we have long asked parents to take the lead and start that open and ongoing conversation with their children.

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.

Preventing unplanned pregnancy is not just about having the "talks" about how babies are made, STDs and the perils of parenting without resources. Kids need to be supported--and invested in--on so many levels before the day even comes for those talks.

Based on my own risky journey with sex as a teen, to me a big part of the "solution" (there isn't one cure-all) comes down to boosting self-respect from many fronts. Imagine from age 0 that kids have a community, role models, school, organizations, family, friends and values around them that support the development of healthy self-respect. Well then risky choices become less of a risk factor, right? This is true for all the biggies that can derail a teen down the line from dating violence to drug abuse to, yes, unplanned pregnancy.

Scientists are making progress in developing a vaginal ring to protect against not only unintended pregnancy but also HIV transmission. As noted by the Global Campaign for Microbicides, "Today's prevention options --condoms, mutual monogamy, and STI treatment-- are not feasible for millions of people around the world, especially women. Many women do not have the social or economic power necessary to insist on condom use and fidelity or to abandon partnerships that put them at risk. Because microbicides would not require a partner's cooperation, they would put the power to protect into women's hands."

Given that women now account for more than one quarter of all new HIV/AIDS diagnoses, that contraception is never one-size-fits-all, and that safe sex means protection from STIs (sexually transmitted infections) as well as unintended pregnancy, safe, microbicidal birth control could be a big step in the right direction.

Last night, MTV premiered "Pedro," a story about his life and a chronicle of his efforts to raise awareness of HIV and AIDS. President Bill Clinton famously called him to tell him how much his efforts meant and that "the country owed him a lot." His eventual death was probably the first time that many young people actually felt that someone they knew and cared about died from a disease that carried a lot of myths, misperceptions and huge stigma.

Such is the power of TV--especially reality TV. We all know in our heads that reality TV isn't real. We know people exaggerate their behavior to get more air time and that they're all competing for their 15 minutes.

But in our hearts we do get attached to these people. We start to care about them in spite of ourselves, and that's why we keep watching. A lot has changed since 1994, when Pedro and his Real World housemates were early pioneers of the entire reality TV phenomenon. But what he did in his short life, what he meant to viewers and what he taught them about living with HIV continues to mean something to real live teens. He proved that someone on TV really can reach through the screen and change lives.

Today, half of all sexually-active young people will contract an STD by age 25--and most won't know it. That's why last night's premiere of "Pedro" kicked off STD Awareness Month, and GYT: Get Yourself Tested, a new public awareness campaign from MTV, the Kaiser Family Foundation and Planned Parenthood Federation of America. GYT is an extension of MTV and Kaiser's "It's Your (Sex) Life" partnership to promote responsible decision making about sex. Check out their newly revamped web site, watch the movie on MTV, and tell us what you think.
