Light-to-moderate alcohol consumption and mortality in the Physicians' Health Study enrollment cohort

Area of Science:

• Epidemiology
• Public Health
• Cardiovascular Research

Background:

• Previous research suggests a J-shaped curve for alcohol and total mortality in men.
• Light-to-moderate alcohol intake may reduce cardiovascular disease (CVD) mortality without increasing other causes of death.

Purpose of the Study:

• To investigate the association between light-to-moderate alcohol consumption and cause-specific mortality in men.
• To clarify the relationship between alcohol intake levels and risks of death from various causes.

Main Methods:

• Prospective cohort study of 89,299 U.S. men (Physicians' Health Study).
• Participants aged 40-84, free of major diseases at baseline (1982).
• Alcohol consumption assessed via food frequency questionnaire; follow-up for 5.5 years.

Main Results:

• A U-shaped relationship observed between alcohol consumption and total mortality.
• Significant risk reduction for death in consumers of 1-6 drinks/week and 1 drink/day.
• Inverse/L-shaped association with CVD mortality, with risk reduction even at >=2 drinks/day.
• No clear benefit or harm for common cancer sites; possible increased risk for other cancers at >=2 drinks/day.

Conclusions:

• Data support a U-shaped relation for alcohol and total mortality in light-to-moderate drinking men.
• The U-shaped curve may be influenced by inverse CVD mortality association and varying cancer risks.
• Findings highlight differential mortality risks based on alcohol consumption levels and cause of death.
