本研究的目的是评估肯尼亚维多利亚湖沿岸渔民的性传播感染 (STI) 患病率和危险因素。这项横断面研究根据每个海滩登记的船只数量，采用按规模比例抽样调查了基苏木地区海滩的 250 名渔民。参与者提供了人口统计和性行为信息、HIV-1 2 型单纯疱疹病毒 (HSV-2) 血液检测和梅毒血清学检测尿液，用于淋病奈瑟菌和沙眼衣原体转录介导的扩增检测，以及阴茎和阴囊拭子用于人乳头瘤病毒 (HPV) DNA 检测。据报告，30% 的人与最近的三位性伴侣一致使用安全套； 38% 的人表示同时存在性伙伴关系，65% 的人表示曾经有过性交易。通过蛋白质印迹测定，HIV 血清阳性率为 26%，HSV-2 血清阳性率为 58%，快速血浆反应素和梅毒螺旋体颗粒凝集测定阳性为 9.5%。 57.2% 的人检测到任何类型的生殖器 HPV DNA，其中 74% 具有两种或多种 HPV 类型。沙眼衣原体和淋病奈瑟菌的检出率分别为 3.2% 和 1.2%。梅毒血清阳性的危险因素包括过去一年在多个海滩工作（调整后比值比 [AOR] 3.81；95% 置信区间 [CI] 1.29-11.28）。 HPV 感染与拥有收音机有关，收音机是较高社会经济地位的标志（AOR 6.33；95% CI 2.94-7.14），并与报告与最近性伴侣的性交易有关（AOR 3.03；95% CI 1.23-7.69）。总之，90% 的渔民有一种或多种性传播感染的证据。这一风险极高的职业群体是预防性干预措施的重中之重。
The aim of this study was to assess prevalence and risk factors for sexually transmitted infections (STIs) among fishermen along Lake Victoria, Kenya. This cross-sectional study surveyed 250 fishermen from beaches in Kisumu District using proportional-to-size sampling based on the number of registered boats per beach. Participants provided demographic and sexual behaviour information, blood for HIV-1 herpes simplex virus type 2 (HSV-2) and syphilis serological tests urine for transcription-mediated amplification assays for Neisseria gonorrhoeae and Chlamydia trachomatis and penile and scrotal swabs for human papillomavirus (HPV) DNA assay. Consistent condom use with the three most recent sexual partners was reported by 30%; 38% reported concurrent sexual partnerships and 65% reported ever having transactional sex. HIV seroprevalence was 26%, HSV-2 seroprevalence by Western blot assay was 58% and 9.5% were rapid plasma reagin and Treponema pallidum particle agglutination assay positive. Genital HPV DNA of any type was detected in 57.2% with 74% of these having two or more HPV types. C. trachomatis and N. gonorrhoeae were detected in 3.2% and 1.2% respectively. Risk factors for syphilis seropositivity included working on multiple beaches during the past year (adjusted odds ratio [AOR] 3.81; 95% confidence interval [CI] 1.29-11.28). HPV infection was associated with owning a radio which is a marker for higher socioeconomic status (AOR 6.33; 95% CI 2.94-7.14) and reporting transactional sex with the most recent sexual partner (AOR 3.03; 95% CI 1.23-7.69). In conclusion, 90% of fishermen had evidence of one or more STIs. This exceptionally high-risk occupational group represents a high priority for preventive interventions.
