Description
Summary:Summary Background Studies on sexually transmitted infections in Brazil are done mainly in large metropolises and screening is available for pregnant women only. We aimed to estimate the prevalence and risk factors for Chlamydia trachomatis, Neisseria gonorrhoeae , and Treponema pallidum infection among young non-pregnant women in non-clinical settings in middle-sized cities of Central Brazil. Methods A cross-sectional community-based sample of 1072 participants was included. Sexually active women (64.9%) provided first-catch urine samples for PCR investigation of chlamydial and gonococcal infection. Syphilis was tested in serum. Univariate analysis investigated risk factors for chlamydial infection. Multivariate logistic regression included associations with a p -value <0.20. Results The mean age of participants was 18 years; 73.2% reported unprotected intercourse, 37.6% were married/cohabiting, and 5% reported a previous STI. Prevalence rates of C. trachomatis , N. gonorrhoeae , and T. pallidum were 9.6% (95% confidence interval (CI) 7.4–12.4%), 0.7% (95% CI 0.2–1.9%), and 0.15% (95% CI 0.0–0.7%), respectively. After adjustments, being <20 years old (adjusted odds ratio (aOR) 1.90, 95% CI 1.07–3.37) and having three or more lifetime sexual partners (aOR 2.57, 95% CI 1.46–4.53) were associated with the risk for chlamydial infection. Conclusions We observed a high prevalence of chlamydial infection and sexual risk behaviors in this population. These findings are important to guide screening strategies in Brazil.
