Abstract: Remnant specimen from 1215 women screening for chlamydia/gonorrhea at 4 different venue types (sexually transmitted disease clinics, home-test kit users, juvenile and adult detention) in Los Angeles, California, were tested for Trichomonas vaginalis. Prevalence of T. vaginalis varied by screening population, and concurrent chlamydia or gonorrhea was independently associated with T. vaginalis.

In an observational study among women screening for chlamydia/gonorrhea, we found that the prevalence of Trichomonas vaginalis infections was relatively high and varied by risk behaviors and concurrent sexually transmitted infection status.
