摘要
Within China, Hepatitis B virus (HBV) infection remains widely prevalent and one of the major public health problems. There have been only two previous estimates of its prevalence at the population level in China, with the latest survey conducted in 2006. A meta-analysis estimated the prevalence of HBV within China between 2013 and 2017 as 7%. This review provides an updated estimate of HBV prevalence in China from 2018 to 2022.Systematic searches of literature from January 1, 2018 to December 25, 2022 were conducted in four international databases (Medline, Web of Science, Embase, Cochrane Database of Systematic Reviews) and three Chinese databases (CNKI, CBM, and WanFang data). Random-effects meta-analyses were conducted to calculate the pooled HBV prevalence with 95% confidence intervals in the overall population and subgroups. Publication bias, heterogeneity between studies, and study quality were assessed.Twenty-five articles were included in the meta-analysis. The pooled prevalence of HBV infection in the Chinese general population from 2018 to 2022 was 3% (95%CI: 2-4%). The prevalence of HBV infection was similar between males and females (both 3%), while rural areas had a higher prevalence than urban areas (3% vs 2%). The highest prevalence of HBV was reported in the eastern provinces (4, 95%CI: 2-6%). The HBV prevalence of people aged ≥18 years old (6, 95%CI: 4-8%) was higher than people aged < 18 years old (0, 95%CI: 0-1%).Compared to the previous meta-analysis prevalence in 2013-2017, the updated meta-analysis estimated prevalence of HBV infection (3%) from 2018 to 2020 showed a decreasing trend, suggesting China had moved into a lower intermediate epidemic area (2-5%). However, the prevalence of HBV in rural areas and eastern regions was still higher than the national average. People aged ≥18 years old showed a higher HBV prevalence. HBV prevention should be prioritized in the highest-prevalence areas and high-risk populations. Due to heterogeneity in data collection methods among studies, there remains a need for systematic surveillance of nationwide HBV prevalence.
