ABSTRACT
Objective To understand the rate of follow-up lost in men who have sex with men (MSM) in a gay bathhouse cohort study in Tianjin and the associated factors.Methods The open cohort study in gay bathhouse was launched in 2012 in Tianjin,and the MSM for baseline survey were recruited from January to June 2012,while the follow up was carried out every six months.A questionnaire survey and HIV test were conducted in the study.The MSM who were HIV negative in the baseline survey in 2012 were used for follow up lost analysis.Univariate and multivariate logistic regression analysis were conducted to identify the factors associated with the lost of follow-up.Results A total of 658 gay bathhouse patrons were recruited in the baseline survey,at the end of 42-month follow-up period,173 of them dropped out (26.3％).Multivariate analysis showed that the MSM who were local residents (OR=0.552,95％CI:0.377-0.808),in Han ethnic group (OR=0.197,95％CI:0.066-0.593),having received HIV test in the last year (OR=0.481,95％CI:0.326-0.710),were male sex workers (OR=0.127,95％CI:0.028-0.585),and believed to be at high risk for HIV infection (OR=0.285,95％ CI:0.125-0.647).They were more likely to receive follow-up but the MSM who were aged ≥35 years (OR=1.891,95％CI:1.022-3.500) were more likely to be lost in the follow-up.Conclusion The lost rate of follow-up in MSM in the gay bathhouse cohort was high in Tianjin.Age,household registration,history of HIV test,the awareness of the risk to be infected with HIV and commercial homosex were factors associated with the follow-up rate in the MSM.It is necessary to conduct similar cohort study in targeted population on the basis of findings of this study.
ABSTRACT
Objective To understand the human papilloma virus (HPV) infection status in men who have sex with men (MSM) recruited from gay bathhouses and HIV voluntary counseling and testing (VCT) clinics in Urumqi,Xinjiang Uygur autonomous region,and identify the associated risk factors.Methods A total of 200 MSM aged ≥≥ 18 years were recruited by using the "snowballing" sampling method from gay bathhouses and VCT clinics in Urumqi during March-May,2016.The MSM recruited completed questionnaires after filling in the informed consent form.The information about their demographic characteristics and sexual behaviors were collected,and anal swabs were collected from them for HPV genotyping.Results The overall HPV infection rate was 54.0％.The HPV infection rate was 66.7％(74/111) in MSM from gay bathhouses and 38.2％(34/89) in MSM from VCT clinics and the high risk type HPV infection rate was 39.6％ (44/111) in MSM from gay bathhouses and 14.6％(13/89) in MSM from VCT clinics,the differences were significant (x2=16.112,P＜0.05;x2=15.190,P＜0.05).Multiple logistic regression analysis indicated that the major risk factors for HPV infection included activity in gay bathhouse (OR=3.732,95％CI:1.950-7.141) and anal sexual behavior (OR=2.555,95％ CI:1.329-4.912).Conclusion The prevalence of HPV in MSM from gay bathhouses was higher than that in MSM from VCT clinics,indicating that close attention should be paid to the behavior intervention in MSM.

ABSTRACT
Objective To explore the positive rates on HIV among men who have sex with men (MSM) who took bathhouse as the major place for sexual practice in China,between 2010 and 2015.Methods Articles published between 2010 and 2015 from CNKI,Wanfang Data,CJFD and PubMed were collected and Stata 12.0 software was used for Meta-analysis.Results A total of 14 articles were selected.Random effects model was employed to calculate the pooled positive rate according to statistical tests for homogeneity with the result f=88.1％.The pooled positive rate appeared as 10.3％,with 95％CI as 7.7％-13.0％.Publication bias was assessed by Egger's test and funnel plot.After stratified analysis on factors as:sample size,year,region and methods on recruitment,the pooled positive rate of HIV appeared higher in people living in the coastal provinces than those in the inland provinces.Conclusion The pooled positive rate of HIV identified from the bathhouses appeared higher than that from other places through,the national HIV sentinel surveillance data,with coastal higher than that in the inland provinces.Bathhouse was recognized as the key place to be caried on intervention programs for the MSM population.
