ABSTRACT

<p><b>OBJECTIVE</b>To determine the feasibility and the effectiveness of HIV risk behavior intervention characterized by initiator taking the lead combined with peer's participation, as to preventing HIV epidemic through promoting condom use and reducing the number of sexual partners among men who have sex with men (MSM) groups.</p><p><b>METHODS</b>Subjects were recruited via peer referral chain. Twelve key MSM were recruited as initiators in bars or other MSM venues in 3 cities of Hefei, Wuhu and Fuyang. Then, each initiator recruited up to 3 MSM to participate and also each of them continued recruiting others. A total of 218 eligible MSM were recruited, and there were four intervention activities conducted. Firstly, twelve initiators were trained according to intervention manual and then intervention activities were implemented by initiators based on their referral chain. Participants were required to complete self-administrated questionnaire at baseline and the third month after intervention finished. The comparison of the results before and after intervention was conducted two months later to see any improvement in HIV/AIDS knowledge, and condom use.</p><p><b>RESULTS</b>Of 218 participants, 170 (77.9%) were followed up in assessment three months later. The results from paired t-Test and Chi Square Test showed that intervention increased HIV/STDs related knowledge (baseline, 14.71 +/- 2.59; follow-up, 16.95 +/- 1.81; t = -10.647, P < 0.01) and the rate of having female sexual partner during previous 2 months (baseline, 17.6%; follow-up, 11.2%; P < 0.01) were of significant differences. Meanwhile, the intervention increased rate of condom use in the last three times of anal intercourse with homosexual partners, casual homosexual partners and primary homosexual partners (baseline, 55.3%, 43.2%, 49.1%; follow-up, 65.2%, 52.2%, 60.9%; chi(2) = 9.979, P < 0.01; chi(2) = 5.797, P < 0.05; chi(2) = 13.082, P < 0.01; respectively) and decreased rate of non-condom use in the last anal intercourse with homosexual partners, casual homosexual partners and primary homosexual partners (baseline, 41.2%, 35.3%, 45.3%; follow-up, 25.3%, 27.1%, 31.2%; P < 0.01, P < 0.05, P < 0.01; respectively) were all of some improvement. Other relevant indicators of 218 participants with 170 followed were compared, excepting the above similar findings, there were no differences in rate of number of female sexual partner during previous 2 months and rate of condom use in the last three anal intercourse with casual homosexual partners and rate of non-condom use in the last anal intercourse with casual homosexual partners.</p><p><b>CONCLUSION</b>HIV risk behavior intervention based on MSM peer groups is feasible and might increase the condom use among MSM.</p>
