Abstract
BACKGROUND
The HIV prevalence among men who have sex with men (MSM) in western China is substantially high and climbing at an alarming rate. We explored the current HIV infection prevalence among MSM from western China and its associated risk characteristics by separately looking at different anal sexual roles.

METHODS
A total sample of 1245 MSM conveniently recruited from multiple sources and areas in the Chongqing and Sichuan region were interviewed with anonymous self-administered questionnaire under investigators’ assistance and received HIV testing. Multivariate logistic regression was used to identify factors independently associated with HIV infection.

RESULTS
Of the 1235 respondents who reported their sexual roles during anal sex with men, the overall HIV antibody-positive rate was 21.21%(262/1235). As for different anal sex roles, HIV-positive rates were significantly higher among men who played the "0.5" role(Versatile, equal) or "0" role (Only bottom or Versatile, but mostly bottom) during anal sex with men than among those who played the role of "1" (Only top or Versatile, but mostly top)(26.41% for "0.5" role, 26.20% for "0" role, and 15.19% for "1" role; χ(2)=22.66, P<0.0001)while statistically significant differences were not found between "0.5" role and "0" role groups (P>0.05). The "1" role MSM who had an education level lower than senior high school, a rural household registration, and low self-perceived severity status of AIDS, the "0.5" role MSM who had an education level lower than senior high school and did not receive HIV testing in recent one year, and the "0" role MSM who were retired or unemployed and diagnosed with sexually transmitted diseases (STD) by doctors in recent six months were more likely to be HIV infected.

CONCLUSIONS
In our study here, the HIV prevalence among MSM is still alarmingly high. Moreover, the "0.5" or the "0" role MSM have a higher risk of infection compared to the "1" role while respective risk characteristics are not totally the same across the three groups. Along with routine preventive intervention services, more focused and specific intervention actions are needed to target anal sex role classes separately.
