Screening for Chlamydia trachomatis in college women on routine gynecological exams.

Chlamydia trachomatis infection poses a serious threat to sexually active college women. Past research has demonstrated the difficulty of predicting infection on the basis of symptoms or physical exam. Recent studies highlight the prevalence of asymptomatic chlamydia infections. This study presents the results of screening 2,303 women for chlamydia infection on routine annual gynecological examinations at a college health center during a 22-month period. A prevalence of 6% was found. The study also assessed the differences between the 140 women identified as chlamydia positive and a control sample of 140 women who were chlamydia negative. The authors compared groups for signs and symptoms that might predict infection, but found no useful predictors. In fact, 79% of the patients who tested positive had no symptoms, and 58% of these had no signs, symptoms, or concurrent infections. Routine screening of women on annual gynecological exam is necessary to bring the chlamydia epidemic under control, the authors conclude.
