(CNSNews.com) - Rep. Stephanie Tubbs Jones (D-Ohio) has introduced a bill urging the House of Representatives to spend more taxpayer money on the prevention, screening and treatment of sexually transmitted diseases.

"We can no longer be silent about this issue, Tubbs Jones said. "The abstinence-only education touted by the Bush Administration is simply not enough."

But a conservative group says a new study by the Heritage Foundation shows that abstinence programs work. Fifteen of the 21 programs reviewed by Heritage analysts showed positive behavioral results, including delay or reduction of sexual activity, said the Family Research Council.

On Wednesday, House Oversight and Government Reform Committee Chairman Henry Waxman (D-Calif.) was holding a hearing on abstinence programs.

Federally funded abstinence-only programs require the exclusive teaching of abstinence until marriage and prohibit teaching about condoms or other contraceptives -- other than to discuss failure rates. These programs have received over $1.3 billion in federal funding over the past decade, the Oversight and Government Reform Committee says on its Web site.

On Wednesday, medical and scientific experts, as well as youth educators, will testify before the committee on evidence of the effectiveness of abstinence-only programs and of "more comprehensive" programs -- those that include mentions of birth control.

The problem

Tubbs Jones says the United States has the highest rate of sexually transmitted infections in the industrialized world. Almost half occur in young people.

"The issue of sexually transmitted diseases has grown to epic proportions in this country," Tubbs Jones said in a news release. "What is most devastating is the toll that STD's are taking on our young women, particularly African American young women."

Pointing to numbers from the federal Centers for Disease Control and Prevention, Tubbs Jones noted that 48 percent of young African American women are infected with an STD compared to 20 percent of young white women.

That 2008 report from the CDC estimated that 1 in 4 young women between the ages of 14 and 19 in the United States, or 3.2 million teenage girls, are infected with at least one of the of the most common sexually transmitted diseases, including human papillomavirus (HPV), chlamydia, herpes simplex virus, and trichomoniasis. These infections can lead to long-term health risks including infertility and cervical cancer.

Tubbs Jones said direct medical costs associated with STDs are as high as $15.3 billion a year.

Studies show abstinence works

The Family Research Council is hailing The Heritage Foundation for its "careful" review of 21 abstinence education programs.

"The research by Christine C. Kim and Robert Rector provides valuable data about the benefits of abstinence education programs and, most importantly, that it is the teens who benefit most," said FRC President Tony Perkins. "This paper also shows that none of the programs had a negative impact, despite what opponents of abstinence claim."

The Heritage researchers said they reviewed at 21 studies of abstinence education. Fifteen of the studies examined programs that were primarily intended to teach abstinence. Of those 15 studies, 11 reported positive findings.

The other six studies analyzed virginity pledges, and of those six studies, five reported positive findings.

"Overall, 16 of the 21 studies reported statistically significant positive results, such as delayed sexual initiation and reduced levels of early sexual activity, among youths who have received abstinence education. Five studies did not report any significant positive results," the Heritage Foundation said on its Web site.

"All of the evidence shows that sexual abstinence is the healthiest behavior for youth," the FRC's Perkins said. "Teaching and equipping youth with the skills to practice this behavior is the goal of genuine abstinence education."

The FRC says the federal government should support "effective" abstinence education programs like those the Heritage Foundation has reviewed, and not promote programs that encourage teens to engage in physically and emotionally risky sexual behavior.

"The government does not promote drug use or underage drinking, and it should not promote risky sexual behavior either," Perkins said.
