Methods A cross-sectional online survey was conducted in Beijing, China in 2016. Participants were users of a popular Chinese gay networking application and had an unknown or negative HIV status. Univariate and multivariate logistic regression analyses were conducted to examine factors associated with HIV self-testing based on adjusted odds ratio （AOR） and 95% confidence interval （CI）. Results Among the 5,996 MSM included in the study, 2,383 （39.7%） reported to have used HIV self-testing kits. Willingness to use an HIV self-test kit in the future was expressed by 92% of the participants. High monthly income （AOR = 1.49; CI = 1.10-2.02; P = 0.010）, large number of male sex partners （≥2： AOR = 1.24; CI = 2.09-1.43; P = 0.002）, sexual activity with commercial male sex partners （〉 2： AOR = 1.94; CI = 1.34 -2.82; P = 0.001）, long-term drug use （AOR = 1.42; CI = 1.23-1.62; P 〈 0.001）, and long-term HIV voluntary counseling and testing （VCT） attendance （AOR = 3.62; CI = 3.11-4.22; P 〈 0.001） were all associated with increased odds of HIV self-testing uptake. Conclusion The nearly 40% rate of HIV self-testing uptake among MSM in our sample was high. In addition, an over 90% willingness to use kits in the future was encouraging. HIV self-testing could be an important solution to help China achieve the global target of having 90% of all people living with HIV diagnosed by 2020.展开更多

Between December 2011 and August 2012, a case-control study was conducted among MSM who underwent voluntary counselling and testing for HIV. Confirmed HIV-positive MSM were included in the case group, and HIV-negative MSM were included in the control group. Information on possible risk factors was collected by a survey questionnaire and a qualitative interview. The results of a conditional logistic regression showed that the following were influencing factors for HIV infection： average monthly income between 2001 and 3000 Yuan （odds ratio （0R）=6.341, 95% Ch 1.714-12.544）, only sometimes using condoms when having anal sex with men in the last 6 months （0R=7.601, 95% Ch 1.359-23.083）, having HIV-positive sex partners （0R=5.273, 95% Ch 1.572- 17.691）, rectal trauma with bleeding in the last 6 months （0R=2.947, 95% Ch 1.308-6.638）, not using condoms at last sexual encounter （OR-- 1.278, 95% Ch 1.012-5.595）, engaging in commercial sex （0R=5.925, 95% Ch 1.923-13.890） and having more than 16 sex partners in the last 6 months （0R=1.175, 95% Ch 1.021-1.353）. These seven factors were the risk factors of HIV infection （OR〉l）. However, having anal sex less than 10 times in the previous 1 month （OR=O.O02, 95% CI： 0.000-0.287） was a protective factor against HIV infection among MSM （OR〈l）, and insertive （0R=0.116, 95% Ch 0.000-0.236） （OR〈l） anal intercourse influenced HIV infection. Interventions should be targeted at MSM whose average monthly income is between 2001 and 3000 Yuan, and who engage in commercial sex. In addition, the importance of using condoms at every sexual encounter should be emphasised in health education, as should the treatment of rectal trauma with bleeding. Finally, MSM should decrease the number of sex partners and frequency of anal sex to decrease the rate of HIV infection.展开更多
