Socio-economic association of alcohol use disorder and cardiovascular and alcohol-associated liver disease from 2010 to 2019.

BACKGROUNDS AND AIMS

Alcohol use leads to disabilities and deaths worldwide. It not only harms the liver but also causes alcohol use disorder (AUD) and heart disease. Additionally, alcohol consumption contributes to health disparities among different socio-economic groups.

METHODS

We estimated global and regional trends in the burden of AUD, liver disease, and cardiovascular disease from alcohol using the methodology of the Global Burden of Disease study.

RESULTS

In 2019, the highest disability-adjusted life years rate per 100,000 population was due to AUD (207.31 [95% Uncertainty interval (UI) 163.71-261.66]), followed by alcohol-associated liver disease (ALD) (133.31 [95% UI 112.68-156.17]). The prevalence rate decreased for AUD (APC [annual percentage change] -0.38%) and alcohol-induced cardiomyopathy (APC -1.85%) but increased for ALD (APC 0.44%) and liver cancer (APC 0.53%). Although the mortality rate for liver cancer from alcohol increased (APC 0.30%), mortality rates from other diseases decreased. Between 2010 and 2019, the burden of alcohol-associated complications increased in countries with low and low-middle sociodemographic index (SDI), contributing more significantly to the global burden.

CONCLUSION

The global burden of AUD, liver, and cardiovascular disease has been high and increasing over the past decade, particularly for liver complications. Lower SDI countries are contributing more to this global burden. There is a pressing need for effective strategies to address this escalating burden.
