绵阳市男男性行为者对HIV感染的防治自信及其影响因素

Self-confidence of prevention and control of HIV infection and its influencing factors among MSM in Mianyang City

目的了解四川省绵阳市男男性行为者(MSM)对预防HIV感染的自信心(简称“防治自信”)情况,分析其影响因素,为制定防治措施提供科学依据。方法2022年1—12月采用“滚雪球”抽样法进行MSM防治自信问卷调查,采用χ^(2)检验和logistic回归模型分析防治自信的影响因素。结果合格问卷976份,83.1%的MSM有防治自信,有防治自信者HIV感染率(1.0%)低于无防治自信者(7.9%)(χ^(2)_(校正)=27.749,P<0.001)。多因素logistic回归分析显示,文化程度大专及以上(OR=1.573,95%CI:1.075~2.300)、本地居住时间>2年(OR=3.042,95%CI:1.709~5.414)、社区网络较大(OR=1.548,95%CI:1.030~2.326)、知晓艾滋病知识(OR=3.107,95%CI:1.015~9.515)、接受预防服务(OR=5.549,95%CI:2.462~12.506)、性角色插入方/均可(OR=1.602,95%CI:1.089~2.355)者有防治自信的可能较大;HIV感染风险较大/很大(OR=0.243,95%CI:0.152~0.391)、害怕感染HIV(OR=0.288,95%CI:0.154~0.536)、无保护肛交(OR=0.444,95%CI:0.294~0.669)者有防治自信的可能较小。结论当地MSM的防治自信总体较好,较大的社区网络、知晓艾滋病知识和接受预防服务的促进作用明显。害怕感染HIV、无保护肛交者的防治自信明显不足,应针对性精准开展行为干预。

Objective To understand the self-confidence in preventing HIV infection(referred to as"prevention confidence")among MSM in Mianyang City,Sichuan Province and to analyze the factors influencing this confidence,so as to provide scientific evidence for developing HIV prevention and control measures.Methods From January to December 2022,a questionnaire survey on self-confidence of prevention and control was conducted using the“snowball sampling”method among MSM.Theχ^(2) test and logistic regression model were employed to analyze the influencing factors of self-confidence of prevention and control.Results Nine hundred and seventy-six eligible questionnaires were collected,83.1%of MSM had self-confidence of prevention and control.The HIV infection rate was 1.0%among those who had self-confidence of prevention and control,significantly lower than the 7.9%among those without it(χ^(2)c orrection=27.749,P<0.001).Multifactorial logistic regression analysis showing that higher self-confidence of prevention and control was associated with having a college education or above(OR=1.573,95%CI:1.075-2.300),residing locally for more than 2 years(OR=3.042,95%CI:1.709-5.414),having a larger community network(OR=1.548,95%CI:1.030-2.326),awareness of AIDS knowledge(OR=3.107,95%CI:1.015-9.515),receiving preventive services(OR=5.549,95%CI:2.462-12.506),and being the insertive or versatile partner in sexual activities(OR=1.602,95%CI:1.089-2.355).Conversely,lower self-confidence of prevention and control was associated with perceiving a higher/greater risk of HIV infection(OR=0.243,95%CI:0.152~0.391),fear of HIV infection(OR=0.288,95%CI:0.154-0.536),and engaging in unprotected anal sex(OR=0.444,95%CI:0.294-0.669).Conclusion Overall,local MSM in Mianyang exhibits good self-confidence of prevention and control.Key factors that enhance self-confidence include larger community networks,awareness of AIDS knowledge,and receiving preventive services.However,fear of HIV infection and unprotected anal sex are significantly undermine people′s self-confidence of prevention and control.Targeted and precise behavioral interventions are necessary to address these issues.
