Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are men aged 50-70 and women aged 55-75 who currently consume between 3 and 40 alcoholic drinks per week.
✕Probably not a fit
Patients with severe psychiatric conditions, liver cirrhosis, or recent breast cancer diagnoses may not benefit from this study.

What this trial studies
This clinical trial aims to evaluate the effects of two different alcohol consumption advisories on health outcomes in over 10,000 Spanish adults aged 50 and older. Participants will be randomly assigned to receive either advice on moderate alcohol consumption following a Mediterranean pattern or advice on complete abstention. The study will last for four years, with participants receiving guidance on their drinking habits and monitoring for all-cause mortality and chronic diseases such as cardiovascular disease and type 2 diabetes. The goal is to determine if moderate drinking is non-inferior to abstention in preventing health issues.
Why it matters
Potential benefit: If successful, this study could provide evidence for more effective alcohol consumption guidelines that balance health risks and benefits.
How similar studies have gone: While there have been nonrandomized studies suggesting benefits of moderate drinking, this trial represents a novel approach with a rigorous randomized controlled design.
