Teens' abstinence pledges found not to work

Teenagers who pledge to remain virgins until marriage are just as likely to have premarital sex as those who do not promise abstinence and are significantly less likely to use condoms and other forms of birth control when they do, according to a study being released today.

The new analysis of data from a large federal survey found that more than half of youths became sexually active before marriage regardless of whether they had taken a "virginity pledge," but that the percentage who took precautions against pregnancy or sexually transmitted diseases was 10 points lower for pledgers than for nonpledgers.

"Taking a pledge doesn't seem to make any difference at all in any sexual behavior," said Janet Rosenbaum of the Johns Hopkins Bloomberg School of Public Health, whose report appears in the January issue of the journal Pediatrics. "But it does seem to make a difference in condom use and other forms of birth control that is quite striking."

The study is the latest to raise questions about programs that focus on encouraging abstinence until marriage. The findings also reignite the debate about the effectiveness of abstinence-focused sexual education just as lawmakers are about to reconsider the more than $176 million in annual funding for such programs.

Rosenbaum analyzed data collected by the federal government's National Longitudinal Study of Adolescent Health, which gathered detailed information from a representative sample of about 11,000 students in grades seven through 12 in 1995, 1996 and 2001.

Rosenbaum focused on about 3,400 students who had not had sex or taken a virginity pledge in 1995. She compared 289 students who were 17 years old on average in 1996, when they took a virginity pledge, with 645 who did not take a pledge but were otherwise similar. She based that judgment on about 100 variables, including their attitudes and their parents' attitudes about sex and their perception of their friends' attitudes about sex and birth control.

By 2001, Rosenbaum found, 82 percent of those who had taken a pledge had retracted their promises, and there was no significant difference in the proportion of students in both groups who had engaged in any type of sexual activity, including giving or receiving oral sex, vaginal intercourse, the age at which they first had sex, or their number of sexual partners.
