摘要
Background:Delayed or inappropriate treatment for sexually transmitted diseases(STDs)increases the risk of HIV acquisition and may cause other harmful outcomes.However,studies on STD treatment-seeking behaviour and correlated factors in men who have sex with men(MSM)are scarce.This information is crucial for the promotion of STD treatment-seeking behaviour and reduction of HIV transmission among Chinese MSM.Methods:During 2012-2013,a multicentre cross-sectional study was conducted in 7 Chinese cities.Participants completed an interview-questionnaire and gave venous blood samples,which were then tested for antibodies to HIV,syphilis,and herpes simplex virus-2(HSV-2).MSM who tested positive for syphilis/HSV-2 or had obvious STD-related symptoms within the last 12 months were defined as suspected STD-infected MSM.Results:Of the 4496 eligible MSM who completed this survey,24.4%(1096/4496)were categorized as suspected STD-infected MSM.35.7%(391/1096)of these MSM with suspected STD infections sought STD treatment in clinics within the last 12 months.Among MSM who did not attend STD clinics for treatment,the prevalence of syphilis and HSV-2 was significantly higher;the HIV prevalence and incidence within this subpopulation reached as high as 14.5%and 12.2/100 person-years,respectively.Multivariate logistic regression analysis indicated that having 7-12 years of education(vs.≤6 years;aOR,2.5;95%CI,1.0-6.1),≥13 years of education(vs.≤6 years:aOR,2.8;95%CI,1.2-7.0),monthly income>500 USD(vs.≤500 USD:aOR,1.5;95%CI,1.1-2.1),obvious STD-related symptoms within last 12 months(aOR,5.3;95%CI,3.7-7.5),being HIV infected(aOR,1.7;95%CI,1.1-2.6),currently syphilis infected(aOR,0.6;95%CI,0.4-0.9)and HSV-2 infected(aOR,0.6;95%CI,0.5-0.9)were independent correlates with seeking STD treatment in clinics among Chinese MSM.Conclusions:The high prevalence of STD infection coupled with a low proportion of individuals who exhibit appropriate treatment-seeking behaviour create a high risk of a growing HIV epidemic among Chinese MSM.Models that prioritize better screening for and education about STDs should be urgently implemented,especially among low-income MSM.
