目的了解三类高危人群的基线情况,为制定中盖项目策略和计划提供参考。方法按照UNAIDS/WHO/FHI有关指南的方法,进行三类高危人群的规模估计、艾滋病相关行为学调查、血清学检测、接受性病服务情况等。结果累计报告HIV/AIDS的传播途径构成中,经异性性接触、注射吸毒、同性性接触传播分别占37.69%、27.24%、5.97%;三类人群具有一定的规模,并分散于不同种类的活动场所;现场调查吸毒人群、暗娼人群、男男性行为人群的艾防知识知晓率分别为80.9%、69.7%、90.4%,接受HIV检测比例分别为55.22%、26.62%、28.50%;男男性行为人群的HIV感染率为5.04%,梅毒感染率为21.49%;暗娼人群、男男性行为人群的最近一个月安全套使用比例分别是73.42%、45.45%,吸毒人群最近六个月共用注射针具的比例是66.70%。结论三类高危人群具有一定的人群规模,在HIV/AIDS传播构成中的比例较大,接受艾滋病相关的检测比例较低,高危行为的比例也较严重,尤其是男男性行为人群的HIV感染率较高,艾滋病防控难度较大。需要构建“三位一体”的模式,加强针对高危人群的预防干预和阳性管理,遏制艾滋病的蔓延。
Objective To understand the baseline conditions of three types of high-risk groups and provide reference for the formulation of strategies and plans for the project. Methods According to the guidelines of UNAIDS / WHO / FHI, three types of high risk population size estimation, AIDS related behavioral survey, serological test and STD service were conducted. Results Reported cumulative transmission of HIV / AIDS in the composition, by heterosexual exposure, injecting drug use, homosexual contact transmission accounted for 37.69%, 27.24%, 5.97%; three groups of people with a certain scale and scattered in different kinds of activities Sites; the knowledge of AIDS awareness of drug abusers, sex workers, and men who have sex with men was 80.9%, 69.7% and 90.4% respectively on the spot and 55.22%, 26.62% and 28.50% respectively on HIV and MSM; HIV infection rate was 5.04% and syphilis infection rate was 21.49%. The proportion of condom use among the sex workers and MSM in the most recent month was 73.42% and 45.45%, respectively. The proportion of sharing needles among drug users in the last six months was 66.70%. Conclusions The three types of high-risk groups have a certain population size, a large proportion in the transmission of HIV / AIDS, a lower proportion of AIDS-related detection and a higher proportion of high-risk behaviors, especially the HIV prevalence in MSM Higher AIDS prevention and control more difficult. There is a need to build a model of “trinity” to strengthen preventive interventions and positive management of high-risk groups to curb the spread of AIDS.
