Study on the relationship between sexual orientation of MSM and their AIDS related behavior

Objective To understand the relationship between sexual orientation of MSM who made their sexualities public and AIDS related behavior.Methods 8qualifiedseedMSM were recruited and were later used to recruit other subjects using snowball sampling method.An anonymous survey regarding AIDS related behavior was conducted and blood samples were collected for serological test.χ2 test and non-conditional logistic regression analysis were used for data statistical analysis.Results A total of 401MSM were recruited in the study.44of them(11.0%)made their sexualities public.The HIV infection rates among MSM who made their sexual orientation public and those who did not were 6.8%(3/44)and 6.4%(23/357),while the accumulative infection rates of syphilis were 15.9%(7/44)and 22.1%(79/357),and the current infection rates were 6.8%(3/44)and 9.5%(34/357)(χ2=0.107,0.900,0.096,P0.05).The single factor analysis showed that age,occupation,marital status,sexual orientation,income,HIV testing in recent 1 year,risk of infection,attitude toward positive result,number of friends of local MSM,family relationship,affection of permanent boyfriend(BF),causes of looking for more sexual partners,anal sex in recent six months,commercial sexual behavior,sexual behavior with females,BF partners,casual sexual partners,oral sex without protection,cumulative number of BF,heterosexual behavior,commercial sexual behaviors were all associated with sexual orientation out of closet(χ2=6.921,3.927,6.678,4.767,7.565,5.083,4.104,6.165,12.455,13.257,14.315,6.471,12.062,10.432,4.951,4.692,7.205,5.019,8.568,7.233,P0.05).Multiple factors analysis indicated that independent factors affecting sexual orientation were income(OR=3.745 95%CI:1.446-9.687),affection of BF(OR=5.863 95%CI:2.25714.256),commercial sexual behavior and number of anal sex in recent six months(OR=8.000 95%CI: 1.468-43.478)(OR=3.706 95%CI:1.324-10.367).MSM with higher income,or in stable relationship or having anal sex at least 5times in recent 6months or having commercial sex behavior were more likely to make their sexuality public.Conclusions Only a few MSM makes sexual orientation public now a days which has a double-sided effect on social and community health.Therefore,health education and behavior intervention need to be carried out based on the specific traits.
