Is male sex workers(MSW) more susceptible to HIV than sex buyers(SB)?

Abstract

Introduction: As both parties to commercial sex, MSW and SB are both at high risk of HIV infection. However, there are few studies on the comparison of HIV infection rates between these two groups of people.Methods: The method of snowball sampling was used to recruit research participants by means of baths, bars, and the Internet. The recruited participants should cooperate with the investigators to complete the questionnaire (including general demographic characteristics, high risky behaviors, status of HIV and AIDS infection, awareness of AIDS knowledge )and blood antibody / antigen tests / oral mucosal exudate antibody tests. The difference analysis was performed using the c2 test, and the correlates of HIV infection were analyzed using logistic regression.Results: The final analysis included 435 MSWs and 729 SBs with HIV infection rates of 7.1% and 2.6%, respectively. Compared with SB, the HIV infection rate of MSW was 2.775 (1.340 -5.746) times higher (after adjusting for age and marital status), 3.173 (1.512-6.659) times higher (after further adjusting the awareness rate of AIDS-related knowledge), 3.688 (1.711-7.950) times higher (after further adjusting the frequency of condom use in homosexual intercourse and commercial sex in the past six months).Conclusions: MSW is more likely to infect HIV than SB. Therefore, effective preventive measures should be focused on MSW.
