Half of urban teenage girls may acquire at least one of three common sexually transmitted infections (STI) within two years of becoming sexually active, according to an Indiana University School of Medicine and Regenstrief Institute study.
The study appears in the December 2009 issue of Archives of Pediatrics and Adolescent Medicine.
The researchers followed 381 girls enrolled at ages 14 to 17 years and found that repeated infection with the organisms that cause chlamydia, gonorrhea and trichomoniasis also was very common.

Within two years, about three-quarters of participants with an initial sexually transmitted STI were diagnosed with a second STI, although not necessarily of the same type. Within four years of an initial STI, virtually all (92 percent) of the participants had a subsequent STI.

The study also found that screening for STI may not be initiated until several years after sexual activity begins, especially for girls with earlier onset of sexual activity.

The study focuses on lower income urban adolescents; a group characterized by early onset of sexual activity, multiple sexual partners, and high STI rates.
As a result of their findings, the researchers call for STI screening in sexually active teenage girls within a year after first intercourse and for retesting of infected girls every 3 to 4 months. Continuing surveillance may be necessary, they conclude, because of the continuing high risk of infection even if the first rescreening test result is negative.
