A heavy-duty study published in the peer-reviewed Archive of Pediatrics & Adolescent Medicine has determined that, contrary to the latest conventional wisdom, abstinence education IS effective in reducing sexual activity in adolescents, more so than other approaches to sex education. HT to Webmonk for pointing me to the original study, which some news reports are not quite understanding. Here is the study, which gives this overview:
Objective To evaluate the efficacy of an abstinence-only intervention in preventing sexual involvement in young adolescents.
Design Randomized controlled trial.
Setting Urban public schools.
Participants A total of 662 African American students in grades 6 and 7.
Interventions An 8-hour abstinence-only intervention targeted reduced sexual intercourse; an 8-hour safer sex–only intervention targeted increased condom use; 8-hour and 12-hour comprehensive interventions targeted sexual intercourse and condom use; and an 8-hour health-promotion control intervention targeted health issues unrelated to sexual behavior. Participants also were randomized to receive or not receive an intervention maintenance program to extend intervention efficacy.
Outcome Measures The primary outcome was self-report of ever having sexual intercourse by the 24-month follow-up. Secondary outcomes were other sexual behaviors.
Results The participants’ mean age was 12.2 years; 53.5% were girls; and 84.4% were still enrolled at 24 months. Abstinence-only intervention reduced sexual initiation (risk ratio [RR], 0.67; 95% confidence interval [CI], 0.48-0.96). The model-estimated probability of ever having sexual intercourse by the 24-month follow-up was 33.5% in the abstinence-only intervention and 48.5% in the control group. Fewer abstinence-only intervention participants (20.6%) than control participants (29.0%) reported having coitus in the previous 3 months during the follow-up period (RR, 0.94; 95% CI, 0.90-0.99). Abstinence-only intervention did not affect condom use. The 8-hour (RR, 0.96; 95% CI, 0.92-1.00) and 12-hour comprehensive (RR, 0.95; 95% CI, 0.91-0.99) interventions reduced reports of having multiple partners compared with the control group. No other differences between interventions and controls were significant.
Conclusion Theory-based abstinence-only interventions may have an important role in preventing adolescent sexual involvement.
President Obama has said that he will base policies on science. So I suppose that means his administration will start championing abstinence-only education.
