Resumo
Genital infections caused by Chlamydia trachomatis are frequent among adolescents and young people. In most cases chlamydial infections are asymptomatic and may cause serious complications such as pelvic inflammatory disease, ectopic pregnancy and infertility. In Brazil there are no screening programs for this infection, with few data about chlamydial prevalence, especially in young women. Objectives: To estimate the prevalence and risk factors for C. trachomatis infection in adolescents and young women, in two cities, Ceres and Catalão, Goiás; to describe the sexual behavior of this population. Methods: The investigation was designed as a cross-sectional survey. Female adolescents and young women between 15 and 24 years old attending the Family Health Program in Ceres and Catalão were randomly assigned. Sociodemographic and sexual behavior data was obtained through a face-to-face interview. Urine samples from young sexually active women were collected and analyzed for the presence of C. trachomatis DNA, using PCR. To identify potential risk factors, univariate analysis was performed. Results: Among the 406 women recruited, 253 were sexually active and eligible for the study. The mean age was 18.7 years (SD=2.9), 58.1% were single, 24.5% initiated sexual life before age 15 and 67% reported inconsistent use of condoms. The overall prevalence of C. trachomatis was 10.9% (CI 95%, 7.0% - 16.1%). Chlamydial infection was more frequent among adolescents and young women who was younger than 15 years at first intercourse (p<0.03), and those who reported less than three partners in life were less likely of being infected with C. trachomatis (p<0.001). Conclusions: This study showed a high frequency of chlamydial infection in an asymptomatic population at Ceres and Catalão, Goiás. Participants reported unsafe sexual behaviors, like early onset of sexual activity without protection and with multiple partners. It is a vulnerable high risk population for sexually transmitted diseases.
