2008-2014年中国预防艾滋病经性传播干预措施落实情况分析

Implementation of intervention programs on AIDS-related sexual transmission in China

目的 分析我国自2008年艾滋病综合防治信息网络直报系统建立以来,艾滋病经性传播高危人群的干预措施落实情况.方法 收集2008-2014年MSM人群、暗娼人群和外来务工人员的干预数据和哨点监测数据,采用历史资料的描述性统计方法分析干预工作各项指标的变化趋势.结果 2008-2012年,MSM人群的月均干预人数和月均干预覆盖率分别从4.9万人和8.6％升至25.2万人和78.5％,暗娼人群月均干预人数和月均干预覆盖率分别从32.9万人和30.9％升至62.5万人和87.0％.2013-2014年两类人群上述指标有小幅回落.全国哨点监测数据显示：MSM人群和暗娼人群的行为学、知晓率指标逐年提高.外来务工人员的干预覆盖率从2008年的4.7％升至2014年的10.0％左右,哨点监测数据显示,男性流动人口的行为学、知晓率指标低于其他高危人群.结论 艾滋病经性传播高危人群的干预措施得到有效落实,干预工作取得一定成效,但新的疫情态势又为艾滋病干预工作提出新的挑战.

Objective To analyze the implementation of intervention programs targeted on AIDS high risk sexual transmission groups since 2008,when the relative prevention and control information systems on HIV/AIDS were developed.Methods Data from both aggregated interventions and sentinel surveillance programs from 2008 to the end of 2014 were used.Descriptive statistics were performed to analyze the trends of implementation on high risk groups including men who have sex with men,female sex workers （FSW） and migrant workers.Results From 2008 to 2012,the monthly average numbers receiving intervention programs and the average monthly coverage rate on intervention for MSM,increased from 49000 to 252000,and from 8.6% to 78.5% respectively.The FSW related indicators increased from 329 000 to 625 000,and from 30.9% to 87.0% respectively.Above indexes on the two populations had dropped slightly in 2013 and 2014.Sentinel surveillance data showed that knowledge and behavior indicators observed from the MSM and FSW populations increased annually.The coverage of intervention programs on migrant workers increased from 4.7% to almost 10.0%,but the surveillance data on migrant men showed that the knowledge and behavior indicators were still lower than the other high-risk groups.Conclusion Intervention related to sexual transmission on HIV/AIDS among high-risk populations were effectively implemented,with some achievements seen.However,as sexual contact currently became the main route of AIDS epidemic,new challenges called for serious attention.
