ABSTRACT
Objective To assess the prevalence of blood donation and associated factors in men who have sex with men (MSM) in China.Methods Our observational study was conducted between January and August,2017 in 3 cities:Guangzhou,Shenzhen and Wuxi.Eligible participants were MSM (≥ 18 years old) who had either ≥2 male sex partners or unprotected anal sex with casual partners,or had been diagnosed with STI in the past 6 months.A self-completed tablet-based questionnaire was used to collect the information about MSM's socio-demographic characteristics,sexual behaviors and blood donation history.Results A total of 603 MSM were enrolled in our study,including 302 in Guangzhou,152 in Shenzhen and 149 in Wuxi,with a mean age of 27.9 years (SD=7.8).Overall,29.2％ (176/603) of the MSM reported a history of blood donation,and 33.1％ (100/302) in Guangzhou,27.6％ (42/152) in Shenzhen and 22.8％ (34/149) in Wuxi,the differences were not significant (x2=6.421,P=0.093).Multivariate logistic regression analysis indicated that MSM had ever tested for HIV for ≥2 times in the past 12 months (vs.MSM tested for HIV one time,aOR=1.49,95％CI:1.08-2.19) or who had ever used gay dating app (vs.MSM who not used gay dating app,aOR=2.13,95％CI:1.12-4.44) were more likely to donate blood.Conclusions Blood donation was common in MSM in China.Health education about blood donation in MSM should be strengthened to ensure the blood safety.
