RESUMEN
Background: Chlamydia trachomatis and Neisseria gonorrhoeae are common sexually transmitted diseases among young women and little has been doing to study them in Chilean adolescents. Aim: Determine the rates of C trachomatis and N gonorrhoeae in Chilean young women. Material and methods: Urine samples were obtained from 203 sexually active females under 25 year-old, who attended hospitals from either high or low-income areas in Chile's capital, Santiago. C trachomatis and Ngonorrhoeae were detected by nucleic acid amplification testing. Results: Seven percent of samples were positive for C trachomatis. AU samples were negative for N gonorrhoeae. Among pregnant women, 19 percent of samples were positive for C trachomatis, while non-pregnant women were positive on 5.5 percent (p =0.04). Systematic use of barrier contraception was referring by 12 percent of women. AU of the latter was free of C trachomatis. No association was observing between age, number of sexual partners, age of first sexual intercourse, and presence of uro-gynecological symptoms, socioeconomic status and the rate of C trachomatis. Conclusions: Seven percent of this group of Chilean young women was infected with C trachomatis. The figure rises to 19 percent if pregnant. Surveillance and screening programs should been implemented to prevent sequels on this vulnerable population.
