Men and women with lower income or education levels are more likely to develop medical conditions related to alcohol abuse compared to similar individuals with a higher socioeconomic status.
This is according to a study – “Socioeconomic position indicators and risk of alcohol-related medical conditions: A national cohort study from Sweden” by Alexis C. Edwards, Sara Larsson Lönn, Karen G. Chartier, Séverine Lannoy, Jan Sundquist, Kenneth S. Kendler, and Kristina Sundquist – that appeared in the journal PLOS Medicine.
The World Health Organization estimates that harmful alcohol use accounts for 5.1% of the global burden of disease and injury worldwide, and results in three million deaths each year. Excessive alcohol consumption can also take an economic toll. Previous studies have identified links between a person’s socioeconomic status and alcohol use, but currently it is unclear how an individual’s social class impacts their future risk of acquiring alcohol-related medical conditions, like alcoholic liver disease.
In this study, researchers used a model that follows people over time to estimate their risk of developing medical conditions from alcohol abuse using two indicators for socioeconomic status: income and education level. The researchers analyzed data from more than 2.3 million individuals in a Swedish database to show that both men and women with a lower income or education level were more likely to develop these conditions.
The researchers found that the associations held true, even when researchers controlled for other relevant factors, such as marital status, history of psychiatric illness and having a genetic predisposition to abuse alcohol.
The findings are important for understanding which populations are most likely to suffer from medical conditions resulting from alcohol abuse, and contribute to a growing body of literature on health disparities that stem from socioeconomic factors.
The researchers recommend that individuals with lower income or education levels might warrant additional screening by clinicians to evaluate their alcohol consumption and identify related conditions.
The authors added: “Among individuals with an alcohol use disorder, those with lower levels of education or lower incomes are at higher risk for developing an alcohol-related medical condition, such as cirrhosis or alcoholic cardiomyopathy. Additional screening and prevention efforts may be warranted to reduce health disparities.”
