Meta-analysis on the positive rate of HIV among MSM with bathhouse as the major venue of sexual practice

Abstract

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. 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. 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 I(2)=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. 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 carried on intervention programs for the MSM population.
