青岛市男性性工作者HIV感染状况及知行分离影响因素分析

Analysis of HIV infection status and influencing factors of separation between cognition of knowledge and sexual behaviors among male sex workers in Qingdao

目的了解青岛市男性性工作者(MSW)HIV感染状况和"安全套使用"知行分离影响因素,为该人群的精准防治提供理论依据。方法2020年9月至2021年6月,在社会组织的协助下,采用线上线下相结合的方式招募MSW,通过问卷收集人口学信息、性行为情况、流动性情况等并进行HIV抗体检测,采用二分类多因素Logistic回归模型分析知行分离的影响因素。结果共纳入229名MSW,平均年龄为27(19,47)岁;平均从业时间为3(0.5,18)年;72.93%(167/229)来自山东省;59.83%(137/229)在近6个月内曾去过两个及以上的城市提供商业性服务。HIV感染率为5.24%(12/229);"安全套使用"知行分离比例为73.36%(168/229)。多因素Logistic回归分析发现,参与群交(OR=7.26,95%CI:3.40~15.47,P<0.01)和了解服务对象HIV感染状况(OR=0.40,95%CI:0.20~0.76,P<0.01)与"安全套使用"知行分离相关。结论青岛市MSW的HIV感染率较高,流动性强,并出现严重的"安全套使用"知行分离现象,需要采取针对性的干预措施,降低该人群HIV感染率。

Objective To understand the HIV infection status of Male Sex Workers(MSW)in Qingdao and the influencing factors of the inconsistency between cognition of knowledge and sexual behaviors related to condom use,to provide a theoretical basis for the precise prevention and treatment in this population.Method With the assistance of social organizations,we recruited MSW through online and offline methods from September 2020 to June 2021,and collected the data of their demographic information,sexual behavior,mobility,etc.via questionnaire surveys and tested their HIV antibody.Factors associated with the inconsistency between cognition of knowledge and sexual behaviors related to condom use were analyzed by binary multivariate unconditional logistic regression.Results A total of 229 MSW were surveyed.The median age was 27 years old(IQR:19-47 years old).The median working time was 3 years(IQR:0.5-18 years).72.93%(167/229)survey participants were from Shandong Province and 59.83%(137/229)had been to two or more cities to provide commercial services in the last 6 months.The HIV infection rate was 5.24%(12/229)and the rate of having inconsistency between cognition of knowledge and sexual behaviors related to condom use was 73.36%(168/229).Multivariate logistic regression analysis found that participating in group sex(OR=7.26,95%CI:3.40-15.47,P<0.01)and understanding the HIV infection status of the clients(OR=0.40,95%CI:0.20-0.76,P<0.01)were influencing factors for the inconsistency between cognition of knowledge and sexual behaviors related to condom use.Conclusion MSW in Qingdao City had a high HIV infection rate,being more mobilized,and had a higher proportion being inconsistent between cognition of knowledge and sexual behaviors related to condom use.It is necessary to adopt targeted intervention measures to reduce the HIV infection rate of this population.
