Introduction:

For decades, low-to-moderate alcohol consumption has been considered by some to offer potential cardiovascular benefits. This comprehensive U.S. modeling study re-evaluated the lifetime health impact of alcohol consumption using contemporary cause-specific data on alcohol-related diseases and injuries.

Why was this study needed?

Current drinking recommendations remain controversial because many previous studies suggested a protective effect of moderate alcohol intake. Updated evidence was needed to quantify the lifetime risks associated with different drinking levels and patterns.

What did the study show?

  • No overall protective health benefit was observed, even at low levels of alcohol consumption.
  • Alcohol-related mortality and morbidity increased progressively with increasing weekly alcohol intake.
  • Lifetime alcohol-attributable mortality exceeded 1 in 1,000 at approximately 7 drinks per week.
  • At around 8–9 drinks per week, the lifetime risk increased to more than 1 in 100.
  • Men consuming 14 drinks per week had an estimated 1 in 25 (4%) lifetime risk of dying from an alcohol-attributable cause.
  • Drinking more than one drink per occasion further increased the risks of breast cancer, cardiovascular disease, and injuries.
  • The findings support limiting alcohol intake to no more than one standard drink per day for both men and women.

Clinical Impact:

These findings challenge the long-held perception that moderate alcohol consumption is beneficial. Clinicians should counsel patients that alcohol-related health risks begin at relatively low levels of intake and increase further with higher weekly consumption and binge drinking patterns.

Take-Home Message:

This large U.S. study found no net health benefit from low-to-moderate alcohol consumption. Alcohol-related health risks rise progressively with increasing intake, supporting a simple public health message: less alcohol is better, and if consumed, intake should ideally be limited to one drink or less per day.
