Results of sentinel surveillance on men who have sex with men in Jilin province between 2010 and 2015

Abstract

Objective: To explore the HIV epidemic and related factors among MSM in Jilin province. Methods: During the implementation of sentinel surveillance program from 2010 to 2015, continuous cross-sectional studies were conducted to monitor the awareness of AIDS, sexual behavior, HIV and syphilis positive rates, with the sample size no less than 400 in each surveillance site. Results: From 2010 to 2015, a total of 7 823 MSM were involved in this study. The overall HIV prevalence among MSM was 5.4% (42/7 823), with an increasing trend during 2010 and 2015 (Trend test χ(2)=110.023, P<0.001). The rates of awareness on AIDS were higher than 90.0%. The proportion of consistent condom use was 27.0% (2 112/7 823) in the last 6 months, and significant differences were found in these years (χ(2)=234.038, P<0.001). Results from multivariate logistic regression analysis showed that the HIV infection related risk factors among MSM in Jilin province would include: residency from other provinces (aOR=1.797, 95%CI: 1.185-2.726), recruitment through internet (aOR=1.717, 95%CI: 1.332-2.215), diagnosed of having sexually transmitted diseases in the previous year (aOR=1.893, 95%CI: 1.356-2.643) and positive testing on syphilis (aOR=4.309, 95%CI: 3.097-5.995). And consistent condom uses in the last 6 months (aOR=0.387, 95%CI: 0.143-0.557), tested HIV in the last year (aOR=0.632, 95%CI: 0.375-0.891) were preventive factors. Conclusions: HIV prevalence was increasing among MSM in Jilin province, but both the proportion of consistent condom use and the former HIV testing rate were at a low level. Aggressive measurement including consistent condom use and periodical HIV testing among MSM was warranted.
