ABSTRACT
Objective To reveal the prevalence and the related factors of hepatitis B (HepB) virus infection among HIV/AIDS patients.Methods We conducted a cross-sectional study in two HIV clinics,affiliated to local Centers of Disease Control and Prevention in Guangxi Zhuang Autonomous Regional.A face-to-face interview,with questionnaire was conducted to collect information on socio-demographic characteristics,drug use,and sexual behavior.Blood samples were used to test HBsAg.x2 test or Fisher's exact test and unconditional logistic regression models were used to identify the influencing factors.Results The prevalence of HBV and HIV co-infection was 13.85％ (113/816).Results from multivariate logistic regression analyses showed that age (25-45),family history of HBV and history of HepB vaccination were independent influencing factors for HBV and HIV coinfection,with OR (95％ CI) as 1.738 (1.031-2.931),2.898 (1.678-5.005) and 1.744 (1.052-2.892),respectively.Conclusion The prevalence of HBV among HIV/AIDS patients was significantly higher than that in general population.HIV/AIDS patients aged between 25 and 45 and with family history of HBV were more likely to be infected with HBV,while HepB vaccination was associated with the reduction of HIV/HBV coinfection.Specific comprehensive prevention and treatment programs on HIV/AIDS patients need to be set up.
