The purpose of this study was to estimate the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in western French Guiana and to analyze associated factors with both infections. A retrospective study was conducted in a sexually transmitted infections clinic in 2017. Women (n = 338) were tested by real-time polymerase chain reaction for vaginal, anal and throat CT and NG infections. Men (n = 192) were evaluated using urine specimens. Socio-demographic and sexual behaviour data were collected by nurses with a structured questionnaire. The prevalence of CT and NG infections among women were 24.3% and 13.3%, respectively, and 12.0% and 7.3% among men. Women aged under 25 years had a higher risk of CT and NG infections than women aged 35 years or more. Another risk factor for CT infection was low educational level, and occasional unprotected sex for NG infection. CT and NG infections were associated with reporting symptoms among men. Very high prevalences of CT and NG infections among women and men were found, which suggest that a large-scale screening strategy should be implemented in French Guiana.

本研究的目的是估计法属圭亚那西部沙眼衣原体(CT) 和淋球菌(NG) 感染的流行率，并分析这两种感染的相关因素。2017 年在一家性传播感染诊所进行了一项回顾性研究。女性 ( n  = 338) 通过实时聚合酶链反应检测阴道、肛门和咽喉 CT 和 NG 感染。男性 ( n = 192) 使用尿液样本进行评估。护士通过结构化问卷收集社会人口统计学和性行为数据。女性 CT 和 NG 感染率分别为 24.3% 和 13.3%，男性分别为 12.0% 和 7.3%。与 35 岁或以上的女性相比，25 岁​​以下的女性感染 CT 和 NG 的风险更高。CT 感染的另一个危险因素是教育水平低，以及偶尔发生 NG 感染的无保护性行为。CT 和 NG 感染与男性症状报告相关。发现女性和男性中 CT 和 NG 感染的患病率非常高，这表明应在法属圭亚那实施大规模筛查策略。
