This study aimed to assess the global, regional, and national burden of liver cirrhosis and other chronic liver diseases between 1990 and 2019, considering five etiologies (hepatitis B, hepatitis C, alcohol use, NAFLD and other causes), age, gender, and sociodemographic index (SDI).
Data on liver cirrhosis and other chronic liver diseases mortality, incidence, and disability-adjusted life years (DALYs) were collected from the Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study 2019.
In 2019, liver cirrhosis and other chronic liver diseases accounted for 1,472,011 (95% UI 1,374,608-1,578,731) deaths worldwide, compared to 1,012,975 (948,941-1,073,877) deaths in 1990. Despite an increase in absolute deaths, the age-standardized death rate declined from 24.43 (22.93-25.73) per 100,000 population in 1990 to 18.00 (19.31-16.80) per 100,000 population in 2019. Eastern sub-Saharan Africa exhibited the highest age-standardized death rate (44.15 [38.47-51.91] per 100,000 population), while Australasia had the lowest rate (5.48 [5.05-5.93] deaths per 100,000 population in 2019). The age-standardized incidence rate of liver cirrhosis and other chronic liver diseases attributed to hepatitis B virus has declined since 1990, but incidence rates for other etiologies have increased. Age-standardized death and DALYs rates progressively decreased with higher SDI across different GBD regions and countries. Mortality due to liver cirrhosis and other chronic liver diseases increased with age in 2019, and the death rate among males was estimated 1.51 times higher than that among females globally.
Liver cirrhosis and other chronic liver diseases continues to pose a significant global public health challenge. Effective disease control, prevention, and treatment strategies should account for variations in risk factors, age, gender, and regional disparities.
