Moderate alcohol intake benefits survival, but heavy weekend or weekday drinking increases mortality risk in women. Even one drink daily on weekdays raises death risk, with over six drinks on weekends posing a significant threat.

Area of Science:

  • Epidemiology
  • Public Health
  • Alcohol Research

Background:

  • Moderate alcohol consumption is linked to improved survival rates.
  • Potential sex differences in alcohol's health effects warrant investigation.
  • Previous studies suggest women may experience less benefit from alcohol.

Purpose of the Study:

  • To investigate the impact of weekday versus weekend alcohol consumption on mortality risk in women.
  • To determine if specific drinking patterns influence survival outcomes.
  • To identify thresholds for alcohol intake associated with increased risk.

Main Methods:

  • A cohort of 17,772 female nurses from the Danish Nurse Association was studied.
  • Baseline data on alcohol intake and lifestyle factors were collected in 1993.

  • Cox proportional hazard models were used to analyze alcohol intake and mortality risk.

    • Main Results:

    • An intake of 1-3 drinks per week was associated with the lowest risk of death.
    • Consuming over six drinks per weekend increased all-cause mortality risk by 3% per additional drink.
    • Drinking one or more alcoholic beverages per weekday increased mortality risk by 4% per drink.

    Conclusions:

    • High alcohol consumption on weekends (over six drinks) is linked to increased mortality.
    • Regular weekday alcohol consumption (one or more drinks per day) also elevates death risk.
    • Specific drinking patterns, not just overall intake, are critical for women's health outcomes.
