This study reveals that alcohol consumption is linearly associated with all-cause mortality in adults under 60. For older adults, the relationship is U-shaped, indicating complex mortality risks across different age groups.

Area of Science:

  • Epidemiology
  • Public Health
  • Biostatistics

Background:

  • Understanding the long-term impact of alcohol consumption on mortality is crucial for public health.
  • Previous research has suggested a U-shaped relationship between alcohol and mortality, particularly in men, but this requires further investigation across diverse age groups.

Purpose of the Study:

  • To examine the relationship between alcohol consumption and all-cause mortality over 15 years in a large, US representative cohort.
  • To investigate how age influences the association between alcohol intake and mortality.
  • To assess the robustness of these associations after adjusting for various lifestyle and health factors.

Main Methods:

  • Analysis of a large US representative cohort with 15 years of follow-up data.

  • Detailed baseline interviews and examinations to collect data on alcohol consumption and potential confounders.
  • Statistical modeling to assess the relationship between alcohol intake and all-cause mortality, with adjustments for nutritional status, smoking, and pre-existing heart conditions.
  • Main Results:

    • A significant linear relationship was observed between alcohol consumption and all-cause mortality for both females and males under 60 years of age at baseline.
    • A non-significant U-shaped relationship was found for individuals aged 60 and older at baseline.
    • These findings remained consistent after adjustments for nutritional variables and smoking.
    • Excluding individuals with a history of heart disease at baseline strengthened the linear relationship in those under 60.
    • The previously reported curvilinear relationship in men was partly attributed to the specific age groups included in prior studies.

    Conclusions:

    • Alcohol consumption demonstrates a distinct age-dependent association with all-cause mortality.
    • Younger adults (<60) show a linear increase in mortality risk with higher alcohol intake.
    • Older adults show a non-linear, U-shaped risk pattern, suggesting a potential protective effect at low-to-moderate consumption levels in this demographic.
