[Prevalence of HBV co-infection in HIV-positive population in China: a systematic review and Meta-analysis].

Objective: To reveal the epidemiologic characteristics of hepatitis B virus (HBV) infection in HIV positive population in China. Methods: We collected research papers published from 2010 to 2019 on HBV co-infection in HIV positive population in China through literature retrieval, screening and quality evaluation. The Meta-analysis was conducted after extracting relevant data from the research papers meeting the inclusion criteria. Results: Twenty-seven studies were included with 69 816 samples. The pooled HBV infection rate in HIV positive population in China was 11.29%. The HBV co-infection rate was higher in the western China (10.73%) and southern China (14.18%), while lower in northern China (6.36%). The HBV infection rates were 11.22%, 12.76%, 9.58%, 11.32% and 10.34%, respectively, in HIV-positive population infected through blood or blood products transfusion, intravenous drug use, homosexual contact, heterosexual contact and unknown transmission routes. Population infected with HIV caused by mother-to-child transmission had the lowest HBV infection rate (2.87%). The HBV infection rate in HIV positive males was 1.29 times higher than that in HIV positive females in southern China. Conclusions: The HBV infection rate in HIV positive population is significantly higher than that in general population. More attention should be paid to the prevention and control of HBV co-infection in HIV positive population.
