Countdown on hepatitis B elimination by 2030: the global burden of liver disease related to hepatitis B and association with socioeconomic status

Hepatitis B virus (HBV) infection causes both acute and chronic liver disease, performing the key driver toward the global elimination of viral hepatitis by 2030. We used data from Global Burden of Disease (GBD) study to quantify the burden of liver disease due to hepatitis B at the global, regional and national levels.Annual incident cases and age-standardized incidence rates (ASIRs) of liver disease due to hepatitis B between 1990 and 2019 were collected from GBD study 2019. Percentage changes of incident cases and estimated annual percentage changes (EAPCs) of ASIRs were calculated to quantify their temporal trends. Correlations between EAPC and socio-demographic index (SDI) and universal health coverage index (UHCI) were evaluated by Pearson correlation analyses.Globally, the incident cases of liver disease due to hepatitis B decreased by 4.51% from 84.45 million in 1990 to 80.65 million in 2019 and ASIR decreased by an average of 1.52% (95%CI - 1.66%, - 1.37%) per year in this period. For the spectrum of liver disease due to hepatitis B, ASIR of cirrhosis and other chronic liver diseases increased by an average of 0.13% (95%CI 0.04%, 0.22%) per year in low SDI region and 0.24% (95%CI 0.04%, 0.34%) per year in low-middle SDI region, and ASIR of liver cancer increased by an average of 0.91% (95%CI 0.37%, 1.46%) per year in high SDI region in 1990-2019. Positive correlations of EAPC in ASIR of liver cancer with SDI and UHCI were observed in nations with SDI ≥ 0.7 or UHCI ≥ 70.HBV infection remains a global health problem, causing low and low-middle SDI regions with an increasing trend of cirrhosis and other chronic liver diseases, and high SDI region with an increasing trend of liver cancer. Efforts to eliminate hepatitis B by 2030 needs to focus on not only developing regions but also developed regions.
