title: [HIV infection status among men who have sex with men in Henan, 2008-2013].
abstract: OBJECTIVE
  To understand the infection status of HIV among men who have sex with men (MSM) in Henan province and provide scientific evidence for the development of AIDS prevention and control measures.
  
  
  METHODS
  The analysis was conducted on the data about incidence of HIV infection and related risk factors among MSM in Henan from 2008 to 2013, which were obtained from AIDS reporting information system and AIDS survey in MSM.
  
  
  RESULTS
  The constituent of HIV infection in MSM increased from 1.3% in 2008 to 17.1% in 2013. The HIV infection rate in MSM increased from 4.69% in 2008 to 8.33% in 2013 (trend χ² = 39.24, P < 0.001). Univariate analysis indicated that the risk factors related with HIV infection included age (χ² = 21.03, P < 0.001), education level (χ² = 31.66, P < 0.001), occupation (χ² = 14.59, P = 0.01), condom use in the last anal sex (χ² = 134.97, P < 0.001), condom use in anal sex during past 6 months (χ² = 97.15, P < 0.001), STI history (χ² = 67.21, P < 0.001) and syphilis prevalence (χ² = 163.60, P < 0.001). Multivariate analysis indicated that HIV infection related risk factors included age, STD history, syphilis prevalence and poor awareness of AIDS related knowledge.
  
  
  CONCLUSIONS
  The incidence of HIV infection among MSM in Henan increased rapidly, and homosexual transmission has become the major route of HIV infection. HIV infection related risk behavior is prevalent among MSM, therefore, it is necessary to take effective measures to prevent and control HIV/AIDS in MSM.
