Background:
This meta-analysis aimed to explore the epidemiological characteristics of alcohol-related liver disease (ALD) in China.
Methods:
Studies published between January 2000 and January 2023 were searched from 3 databases in English and 3 databases in Chinese. DerSimonian-Laird's random-effects model was adopted to calculate the pooled prevalence.
Results:
A total of 21 studies were included. The pooled prevalence of ALD was 4.8% (95% CI, 3.6%-6.2%) in the general population, 9.3% (95% CI, 4.4%-16.0%) in males, and 2.0% (95% CI, 0.0%-6.7%) in females. The prevalence was the highest in western China (5.0% [95% CI, 3.3%-6.9%]) and the lowest in central China (4.4% [95% CI, 4.0%-4.8%]). The prevalence among people with different drinking histories (less than 5 years, 5 to 10 years, and over 10 years) was 0.9% (95% CI, 0.2%-1.9%), 4.6% (95% CI, 3.0%-6.5%), and 9.9% (95% CI, 6.5%-14.0%), respectively. The prevalence in 1999-2004 was 4.7% (95% CI, 3.0%-6.7%) and then changed from 4.3% (95% CI, 3.5%-5.3%) in 2005-2010 to 6.7% (95% CI, 5.3%-8.3%) in 2011-2016.
Conclusions:
The prevalence of ALD in China has increased in recent decades, with population-related variations. Targeted public health strategies are needed, especially in high-risk groups, such as male with long-term alcohol drinking.
Trial Registration:
The registration number on PROSPERO is CRD42021269365.
