About

The goal of this clinical trial is to test two advices on alcohol drinking in more than 10.000 Spanish adult drinkers (men of 50 or more years and women of 55 or more years).

The main question it aims to answer is to test the non-inferiority advice of a moderate alcohol drinking pattern on all-cause mortality and other chronic disease like cardiovascular disease, cancer or type 2 diabetes.

Participants will receive during 4 years an advice to drink alcohol following a Mediterranean Alcohol Drinking Pattern (MADP): consuming alcohol in moderation, avoidance of binge drinking and preference for red wine.

Researchers will compare those who will receive a MADP advice with those who will receive an advice on abstention to see if the advice on MADP is not inferior than the abstention advice to prevent all-cause mortality and other chronic diseases.

Full description

Policymakers and clinicians are currently perplexed on how to reduce alcohol harms in drinkers, because of contradictory guidelines: abstention is proposed as the healthiest option by many health advocates, stating that "there is no safe level of alcohol intake"; but most nonrandomized studies found lower all-cause mortality and other beneficial outcomes in moderate drinkers than in abstainers among subjects >50 years. However, potential biases may compromise these latter studies, particularly when effects are null or moderate. A large pragmatic randomized controlled trial (RCT) of realistic advice aimed to change behaviour addressing clinical endpoints is long overdue. It will provide first-level evidence to confront the harms of one of the most widely used substances by humankind.

The European Research Council has funded, through an Advanced Research Grant (2023-2028) to the University of Navarra (Spain), as Host Institution, a 4-year non-inferiority RCT with more than 10,000 drinkers (men 50-70 years or women 55-75 years consuming 3 or more but 40 or less drinks/wk). The name of the trial is UNATI (University of Navarra Alumni Trialist Initiative).

At least ten thousand drinkers will be randomized in a 1:1 ratio to repeatedly (4 contacts/year) receive during 4 years two different advices:

1. abstention;
2. moderation (7 or less drinks/wk in women and 14 or less drinks/wk in men), avoidance of binge drinking, with preference for red wine consumed always with meals, and consumption spread out throughout the week, following the traditional Mediterranean Alcohol Drinking Pattern (MADP). Moderate consumption is hypothesized to be non-inferior. No initiation or increment in alcohol intake will be promoted.

The primary endpoint will be a global index of all-cause mortality, cardiovascular events, any invasive cancer, liver cirrhosis, type 2 diabetes, depression, dementia, injury requiring hospital admission or tuberculosis or other infections requiring hospitalization. As a secondary analysis, the most severe outcomes (mortality, invasive cancer, stroke, myocardial infarction, liver cirrhosis) will be considered independently with sufficient priority over less severe outcomes, using ad hoc methods.

The UNATI trial will provide for the first time an evidence-based answer to a question of the utmost interest in clinical medicine, given the high prevalence of moderate alcohol intake, and the current situation of equipoise with opposing views in the scientific community on the most sensible advice for moderate drinkers. The starting date for the project is December 1, 2023. The randomization of participants will start on June 2024.
