The study aimed to assess the prevalence of Neisseria gonorrhoeae and Chlamydia trachomatis infections and identify demographic, behavioral and clinical factors correlated with such infections in men attending six sexually transmitted disease clinics in Brazil.
Multicentric, cross-sectional study performed among men attending STD clinics in Brazil. The study included STD clinics in six cities distributed throughout the five geographic regions of Brazil in 2005. Patients provided 20 ml of first catch urine for testing for NG and CT by DNA-PCR.
A total of 767 (92.9%) men were included in the study. The mean age was 26.5 (SD 8.3) years-old. Prevalence of Chlamydia infection was 13.1% (95%CI 10.7%-15.5%) and gonorrhea was 18.4% (95%CI 15.7%-21.1%). Coinfection prevalence was 4.4% (95%CI 2.95%-5.85%) in men who sought attendance in STI clinics. Factors identified as associated with C. trachomatis were younger age (15-24) [OR=1.4 (95%CI 1.01-1.91)], present urethral discharge [OR=4.8 (95%CI 1.52-15.05)], genital warts [OR=3.0 (95%CI 1.49-5.92)] and previous history of urethral discharge [OR=2.4 (95%CI 1.11-5.18)]. Variables associated with gonorrhea were younger age (15 to 24) [OR=1.5 (95%CI 1.09-2.05)], presence of urethral discharge [OR=9.9 (95%CI 5.53-17.79)], genital warts [OR=18.3 (95%CI 8.03-41.60)] and ulcer present upon clinical examination [OR=4.9 (95%CI 1.06-22.73)].
These findings have important implications for education and prevention actions directed toward men at risk of HIV/STD. A venue-based approach to offer routine screening for young men in STD clinics should be stimulated.
本研究旨在评估淋病奈瑟菌和沙眼衣原体感染的流行率，并确定与巴西六家性传播疾病（STD）诊所就诊男性感染相关的人口统计学、行为和临床因素。
这是一项多中心、横断面研究，纳入了巴西 STD 诊所的男性患者。该研究于 2005 年在巴西五个地理区域的六座城市的 STD 诊所进行。患者提供 20ml 首段尿液，通过 DNA-PCR 检测 NG 和 CT。
共纳入 767 名（92.9%）男性。平均年龄为 26.5（8.3）岁。衣原体感染率为 13.1%（95%CI 10.7%-15.5%），淋病为 18.4%（95%CI 15.7%-21.1%）。在因性传播感染就诊的男性中，合并感染率为 4.4%（95%CI 2.95%-5.85%）。与沙眼衣原体感染相关的因素为年龄较小（15-24 岁）[比值比（OR）=1.4（95%可信区间（CI）1.01-1.91)]、存在尿道分泌物（OR=4.8（95%CI 1.52-15.05)]、生殖器疣（OR=3.0（95%CI 1.49-5.92)]和既往尿道分泌物史（OR=2.4（95%CI 1.11-5.18)]。与淋病相关的变量为年龄较小（15 至 24 岁）[OR=1.5（95%CI 1.09-2.05)]、存在尿道分泌物（OR=9.9（95%CI 5.53-17.79)]、生殖器疣（OR=18.3（95%CI 8.03-41.60)]和临床检查时存在溃疡（OR=4.9（95%CI 1.06-22.73)]。
这些发现对针对感染 HIV/STD 风险男性的教育和预防措施具有重要意义。应该鼓励在 STD 诊所对年轻男性进行常规筛查。
