HIV Related High Risk Behaviors and Willingness to Participate in HIV Vaccine Trials among China MSM by Computer Assisted Self-Interviewing Survey

Background. The number of new HIV infections among MSM of China is rapidly increasing in recent years and behavioral interventions have had limited effectiveness. To control the HIV pandemic may lie in an HIV vaccine. This study examined the factors associated with willingness to participate (WTP) in HIV vaccine clinical trials among China MSM. Methods. A cross-sectional survey was carried out among MSM from three cities in northeast China. Questionnaires pertaining to MSM risk behavior and WTP in HIV vaccine trials were administered through computer assisted self-interviewing (CASI). Results. A total of 626 MSM participated in this survey. 54.8% had occasional male partners and 52.2% always used condoms with male sex partners. HIV prevalence was 5.0%. 76.7% were WTP in a preventive HIV vaccine clinical trial. Results showed that HIV vaccination is a means of protection for spouses and family; family support to participate in vaccine trials and desire for economic incentives were significantly associated with WTP. Conclusions. There was a high proportion of WTP in HIV vaccine trials among Chinese MSM. The high HIV prevalence and high proportion of risky sexual behavior indicate that Liaoning MSM are potential candidates for HIV vaccine trials.
