To study the situation of HIV infections among men who have sex with men (MSM) in Tianjin during 2008 - 2009 and to provide reasonable evidence for intervention strategy.
Transect investigations in MSM were conducted three times during 2008 - 2009. Blood samples were collected and detected to identify the recent HIV infection with IgG-capture BED-enzyme immunoassay (BED-CEIA) before HIV incidence was estimated.
1799 specimens were tested and the HIV prevalence rates of each study were 6.7%, 8.6% and 6.2%, while the incidence rates were 2.7%, 2.5% and 2.8%, respectively. The estimated incidence rates among these testees were 5.36% and 5.52% per year in 2008 and 2009.
of this study showed that the HIV incidence stabilized at high level among MSM in Tianjin, calling for the effective interventions be taken for HIV/AIDS control and prevention.
了解2008 - 2009年天津市男男性行为人群（MSM）艾滋病病毒（HIV）感染状况，为制定干预策略提供科学依据。
于2008 - 2009年对MSM人群进行了3次横断面调查。采集血样，采用IgG捕获BED-酶免疫分析（BED-CEIA）法检测近期HIV感染情况，进而估算HIV发病率。
共检测1799份标本，各次调查的HIV感染率分别为6.7%、8.6%和6.2%，发病率分别为2.7%、2.5%和2.8%。2008年和2009年受试人群的年发病率估计分别为5.36%和5.52%。
本研究结果表明，天津市MSM人群HIV发病率处于较高水平且趋于稳定，需采取有效干预措施控制和预防艾滋病。
