Public health policies and alcohol-related liver disease

Alcohol-related liver disease (ALD) represents a major public health problem worldwide. According to the World Health Organization, the highest levels of per capita alcohol consumption are observed in countries of the European Region. Alcohol consumption is also alarmingly increasing in developing countries. ALD is one of the main contributors to the burden of alcohol-attributable deaths and disability. In the United States, severe forms of ALD such alcoholic hepatitis have increased in the last decade and in the United Kingdom, three-quarters of liver-related mortality results from alcohol consumption. Besides genetic factors, there is strong evidence that the amount of alcohol consumed plays a major role in the development of advanced ALD. Establishing effective public health policies is therefore mandatory to reduce the burden of ALD. Since the 90s, major public health institutions and governments have developed a variety of policies in order to reduce the harm caused by excessive drinking. These policies encompass multiple factors, from pricing and taxation to advertising regulation. Measures focused on taxation and price regulation have been shown to be the most effective at reducing alcohol-related mortality. However, there are few studies focused on the effect of public policies on ALD. This review article summarises the factors influencing ALD burden and the role of different public health policies.
