Contribution of alcohol use to the global burden of cirrhosis and liver cancer from 1990 to 2019 and projections to 2044.

BACKGROUND

Identifying the temporal trends of cirrhosis and liver cancer attributable to alcohol use in both the past and the future can formulate the control strategies.

METHODS

Data on cirrhosis and liver cancer attributable to alcohol use from 1990 to 2019, including mortality and disability-adjusted life year (DALY) rates were collected from the 2019 Global Burden of Disease (GBD) study. To analyze the temporal trends, the average annual percentage change (AAPC) was calculated, and the Bayesian age-period-cohort model was applied.

RESULT

Deaths and DALY of cirrhosis and liver cancer attributable to alcohol use increased year by years, but the age-standardized death rate (ASDR) and age-standardized DALY rate declined or remained stable from 1990 to 2019 in most regions of the world. The burden of cirrhosis attributable to alcohol increased in low-middle social-development index (SDI) regions, while the burden of liver cancer increased in high-SDI regions. Eastern Europe and Central Asia have the highest burden of cirrhosis and liver cancer caused by alcohol use. Deaths and DALYs are mainly distributed in people aged 40+ years, but there is an increasing trend in people aged under 40 years. New deaths from cirrhosis and liver cancer attributable to alcohol use are predicted to increase in the next 25 years, but the ASDR of cirrhosis in males will increase slightly.

CONCLUSIONS

Although the age-standardized rate of cirrhosis and liver cancer due to alcohol use have decreased, the absolute burden increased and will continue to increase. Therefore, alcohol control measures should be further strengthened and improved through effective national policies.
