ObjectiveTo determine the association between recreational drug usage， high risk sexual behavior， and HIV infection among men who have sex with men（MSM） in Jinhua.
MethodsA cross-sectional survey was conducted to recruit MSM for anonymous questionnaire survey and serological examination. We used EpiData3.1 for data entry and SPSS 19.0 for statistical analysis.
ResultsA total of 368 MSM were surveyed， in which the proportion of recreational drug usage was 13.3% （ 49 / 368 ）， with the HIV infection of 10.3% （38/ 368 ） and syphilis infection of 8.9% （25/368）. Risk factors associated with recreational drug usage were determined to be part-time job or being unemployed （OR=5.26； 95%CI： 2.10-13.18； P<0.001）， average monthly income ≥CNY 5 000 （OR=6.45； 95%CI： 2.87-14.61； P<0.001）， education level of high school or above （OR=1.56； 95%CI： 1.37-3.57； P=0.037）， sexual orientation being homosexual （OR=3.52； 95%CI： 1.60-7.33； P=0.002）， number of sexual partners >1 （OR=4.37； 95%CI： 1.76-10.82； P=0.001）， engaged in group sex （OR=7.90； 95%CI： 2.11-29.55； P=0.002） and previously diagnosed sexually transmitted diseases （OR=4.76； 95%CI： 1.29-17.65； P=0.019）.
ConclusionPrevalence of recreational drug usage among MSM in Jinhua is relatively low. MSM with part-time or unemployed status， monthly income ≥CNY 5 000， higher education level， homosexual orientation， multiple sexual partners， sexually transmitted diseases and group sex behavior are the risk factors associated with recreational drug usage in Jinhua city. Targeted countermeasures should be considered for intervention.
