Objective        To understand human immunodeficiency virus (HIV) infection rate and its influencing factors among male migrant workers who have sex with men (MSM)

and to provide scientific suggestions for the intervention of MSM.       Methods        MSM were recruited through peer recommendation

interviewed by face-to-face questionnaire and examined for HIV and syphilis in their blood samples. The data were analyzed to describe HIV infection rate and relevant behavior characteristics. The influencing factors of HIV infection rate were identified by multivariate Logistic regression analysis.       Results        A total of 140 MSM were recruited with an average age of (35.1±9.7) years. The rate of AIDS cognition was 72.9%

and the rate of receiving behavior intervention in the past year was below 50%. In the past 6 months

87.9% of the MSM had anal sex with men

and the rate of condom use was 29.3%. In the past 6 months

41.4% of them had sex with women

and the rate of condom use was 10.3%. The prevalence of HIV and syphilis was 20.7% and 9.3%

respectively. The results of multivariate logistic regression analysis suggested that age (OR=3.02

95%CI: 1.63-5.59)

receiving free condom in the past year (OR=0.22

95% CI: 0.09-0.57) and syphilis infection (OR=4.12

95%CI: 1.06-15.96) were independent influencing factors for HIV infection.       Conclusion      Those factors such as poor AIDS cognition

low rate of receiving behavior intervention

high proportion of having sex with women

low rate of condom use and high prevalence of HIV and syphilis among MSM will accelerate HIV transmission among MSM and promote HIV transmission to general population due to the bisexual behavior.
