Changes in alcohol consumption with age
1Gerontology Centre, Memorial University of Newfoundland, St. John's, Canada.
Summary
Older adults drink less alcohol per occasion, not less often. Education increases drinking frequency but reduces quantity consumed. Gender differences in alcohol intake are partly explained by body composition.
Area of Science:
- Sociology
- Public Health
- Epidemiology
Background:
- Understanding alcohol consumption patterns is crucial for public health initiatives.
- Previous research indicates variations in alcohol intake across different demographics.
Purpose of the Study:
- To analyze alcohol consumption patterns in adults in metropolitan St. John's.
- To investigate factors influencing age-related and gender-related differences in alcohol consumption.
Main Methods:
- Telephone survey of adults in a representative household sample.
- Regression analyses to examine relationships between demographic factors and alcohol consumption.
Main Results:
- Age-related decline in total alcohol consumption is due to reduced amount per occasion, not fewer occasions.
- Higher education correlates with more frequent drinking occasions but lower consumption per occasion.
- Gender differences in consumption are partly explained by body size and water content, but not age-related changes.
Conclusions:
- Alcohol consumption patterns change with age, primarily in quantity per occasion.
- Educational attainment influences drinking frequency and intensity.
- Physiological factors partially explain gender differences in alcohol intake, but not age-related trends.
