Korean study highlights impact of frequent alcohol consumption on healthcare costs

Frequent alcohol consumption has a significant economic impact on healthcare systems, generating substantial additional costs and requiring specific public policies to reduce them. A recent study conducted in South Korea identified significant increases in healthcare costs associated with frequent alcohol consumption.

A recent study (1) conducted in South Korea analyzed data from a longitudinal cohort of 62,965 adults aged 40 to 69 years, with the aim of investigating the additional healthcare costs associated with frequent alcohol consumption. Using information collected by the National Health Insurance Service of Korea (NHIS-NSC), the study followed participants over a decade, allowing a detailed assessment of the costs related to different levels of alcohol consumption in the long term.

The results highlighted that frequent alcohol consumption has a significant economic impact on healthcare costs. Men who consumed alcohol almost daily had 21.4% higher costs compared to non-drinkers. Among women, the impact was even more significant, with an increase of 31.8%, corresponding to additional annual expenditures of up to US$433 for women and US$284 for men.

The study also showed that the frequency of consumption plays a crucial role in costs. Among men, moderate consumption (1 to 2 times per month or week) was associated with lower costs compared to non-consumers. However, as frequency increased to 3 or more times per week, health expenditures increased significantly.

These findings emphasize the relevance of public policies focused on reducing frequent and excessive alcohol consumption to alleviate the financial burden on health systems.

Based on the findings, some practical recommendations are important:

1. Strengthen educational campaigns on the economic and health risks related to frequent and excessive alcohol consumption.

1. Implement preventive programs and specific interventions for groups that consume alcohol almost daily.

1. Promote strategies for responsible consumption, especially among vulnerable groups, such as women and older adults.
