目的 分析广西某市2016-2021年女性性工作者(Female sex workers,FSWs)梅毒感染情况及其影响因素,为防控策略提供依据.方法 使用《国家艾滋病哨点监测FSW调查问卷》开展调查,用ELISA和RPR/TRUST检测梅毒感染情况,运用二元Logistic回归分析梅毒感染的影响因素.结果 本次共调查3564人,总体梅毒感染率为5.61％.2016年梅毒检出率为8.85％,小学及以下文化程度的梅毒感染率为8.49％,低档性交易场所工作的FSWs梅毒感染率为11.75％,前一个工作地点位于外地的FSWs梅毒检出率为8.81％,HIV阳性感染者的梅毒感染率为13.85％.多因素分析结果显示,年龄≥35岁(AOR=1.989,95％CI:1.276～3.102)的FSWs相比于年龄＜35岁更有可能感染梅毒;相比于中/高档次的性交易场所,在低档次场所工作(AOR=3.477,95％CI:2.444～4.945)的FSWs更具有感染梅毒的风险(P＜0.05).结论 广西某市FSWs人群的梅毒感染率与年龄、文化程度、性交易场所的档次等因素有关.相关部门须加强对年龄大于35岁、低文化程度、低档次场所工作的FSWs人群的性病干预,降低广西某市FSWs人群的梅毒感染率.
The prevalence of syphilis infection and associated factors among female sex workers in a city of Guangxi from 2016 to 2021
Objective Todetermine the prevalence and associated factors of syphilis infection among female sex workers(FSWs)in a city of Guangxi Province.Methods The National AIDS Sentinel MonitoringFSW Questionnaire was used to interview FSWs recruited in a city of Guangxi from 2016 to 2021.Syphilis infection was tested by ELISA and RPR/TRUST.The associated factors of syphilis infection were analyzed by Logistic regression.Results A total of 3564 people were recruited,and the overall prevalence of syphilis was 5.61％.In 2016,the syphilis positive rate was 8.85％,the syphilis positive rate of FSWs with primary education level and below was 8.49％,the syphilis positive rate of FSWs worked in low-grade sex trading places was 11.75％,the syphilis positive rate of FSWs worked in other places before was 8.81％,and the syphilis positive rate of HIV-positive people was 13.85％.The results of multivariate analysis showed that the preva-lence of syphilis was higher in FSWs aged 35 years and above(AOR=1.989,95％CI:1.276-3.102)compared with those aged under 35 years.FSWs worked in low-grade sex trade places(AOR=3.477,95％CI:2.444-4.945)had high-er risk of syphilisinfection than those with medium/high-grade workplaces(P＜0.05).Conclusion The prevalence of syphilis infection among FSWs in a city of Guangxi is associated with factors such as age,educational level,and the level of sex trade venues.Relevant departments need to strengthen sex transmitted disease intervention measures for FSWs who were aged 35 years and above,with lower educational level or worked low-level sex venue to reduce the prevalence of syphilis in a city of Guangxi.
