PMID 41919824WHAT IT FOUND
Alcohol use before infection did not directly cause long COVID, but it was associated with hospitalization, which was directly related to long COVID.
Nurses should screen for alcohol use to identify patients at higher risk of severe acute disease requiring admission.
Key findings
01Alcohol use before COVID-19 was not directly associated with the occurrence of long COVID.
02Alcohol use before COVID-19 was positively associated with hospitalization, with each unit increase in alcohol use linked to about a 7% higher chance of being hospitalized.
03Hospitalization for COVID-19 was directly related to the development of long COVID.

What it does not show
The study relies on self-reported data regarding alcohol consumption, which may be subject to recall bias or social desirability bias. The cross-sectional design limits the ability to establish strict causality between alcohol use and outcomes, although path analysis models were used to explore relationships. The sample was drawn from a specific region in Brazil, which may limit generalizability to other populations with different drinking patterns or healthcare systems.
Declared interests
The study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), a Brazilian government agency. No commercial conflicts of interest were reported.
The easy way to misread this
Do not conclude that alcohol consumption directly causes long COVID. The study found no direct link; rather, alcohol use was associated with a higher likelihood of hospitalization, and hospitalization was associated with long COVID. This is an indirect pathway, not a direct causal effect of alcohol on the chronic condition itself.
