A study published in the December 2002 issue of Pediatrics, the peer-reviewed scientific journal of the American Academy of Pediatrics (AAP), titled "When and Where Do Youths Have Sex? The Potential Role of Adult Supervision" looked at more than 2,000 high school students, comparing after-school supervision with sexual activity. Here's what the study found:

• Among the respondents who had had intercourse, 91 percent had last done so in a home setting.

• Fifty-six percent had had intercourse on a weekday.

• Youths who were unsupervised for 30 or more hours per week were more likely to be sexually active compared with those who were left alone for five hours a week or less.

• Those left unsupervised for more than five hours per week had more sexually transmitted diseases, particularly the boys.

The conclusion? The authors suggest that supervised activities for teens might reduce sexual risk-taking.
