The AIDS sentinel surveillance analysis among men who have sex with men of Mianyang City in 2015

Abstract: Objective This work was to understand the status of AIDS epidemic, knowledge awareness, sexual behavior and influencing factors of HIV among men who have sex with men (MSM). Methods With snowball sampling method and informed consent in a fixed location, subjects were recruited from MSM of Mianyang City for a self-administered anonymous questionnaire survey and serological testing during February-June, 2015. Results Among the total of 436 subjects, the rate of knowledge awareness of HIV / AIDS was 98.4% (429/436), and 75.0% (327/436) did HIV test and were aware of the results in the past one year. The intervention services coverage was 92.0% (401/436) in the past one year. 8.3% (36/436) was confirmed as HIV positive, and 7.6% (33/436) was infected with syphilis. By multifactor analysis, high school or higher education(OR =0.366，95% CI:0.146～0.918), intervention service coverage (OR =0.154, 95%CI:0.056～0.427) were protection factors for HIV infection. Unprotected anal sex in the past 6 months was a risk factor (OR =2.924, 95%CI:1.211～7.092) (all P＜0.05). Conclusion Among MSM in Mianyang, MSM knowledge awareness about AIDS , intervention service coverage and condom use were relatively higher. The incidence of HIV was relatively lower, but rebounded recently. Time detection and education of HIV among MSM should be strengthened to promote the prevention and control of HIV/AIDS among MSM.
