Applying an equity lens to liver health and research in Europe.

Liver disease is a major cause of premature death and disability in Europe. However, morbidity and mortality are not equally distributed in the population. In spite of this, there are few studies addressing the issue of health inequalities in Europe. In this Public Health Corner article, we compare the research conducted on health inequalities in Europe to other settings and highlight the main differences based upon an extensive review of the literature. We report that only 10.2% of studies were led by European institutions or conducted in European populations and that certain topics such as alcohol-related liver disease are largely overlooked. In addition, we discuss the relevance of including a health equity lens when conducting clinical, epidemiological and health systems' research in liver disease and set out the basic requirements to tackle health inequalities in liver disease in Europe.
