Sex Infections Found in Quarter of Teenage Girls

The first national study of four common sexually transmitted diseases among girls and young women has found that one in four are infected with at least one of the diseases, federal health officials reported Tuesday.

Nearly half the African-Americans in the study of teenagers ages 14 to 19 were infected with at least one of the diseases monitored in the study — human papillomavirus (HPV), chlamydia, genital herpes and trichomoniasis, a common parasite.

The 50 percent figure compared with 20 percent of white teenagers, health officials and researchers said at a news conference at a scientific meeting in Chicago.

The two most common sexually transmitted diseases, or S.T.D.’s, among all the participants tested were HPV, at 18 percent, and chlamydia, at 4 percent, according to the analysis, part of the National Health and Nutrition Examination Survey.

Each disease can be serious in its own way. HPV, for example, can cause cancer and genital warts.

Among the infected women, 15 percent had more than one of the diseases.

Women may be unaware they are infected. But the diseases, which are infections caused by bacteria, viruses and parasites, can produce acute symptoms like irritating vaginal discharge, painful pelvic inflammatory disease and potentially fatal ectopic pregnancy. The infections can also lead to longterm ailments like infertility and cervical cancer.
