Purpose
To investigate age-related differences in the relationships among at-risk alcohol consumption, alcohol use disorder (AUD), and psychological distress with a special focus on older adults.
Methods
We used a nationwide cross-sectional study of a representative sample of community-dwelling adults from the Korean Epidemiologic Catchment Area study for psychiatric disorders conducted by door-to-door interviews. The Korean version of the Composite International Diagnostic Interview was applied. Subjects were categorized into four age groups: young-to-middle-aged (20–54 years), near-old (55–64 years), early-old (65–74 years), and late-old (≥ 75 years). The associations among at-risk drinking, alcohol use disorder, and psychological distress were examined according to age groups.
Results
Among a total of 5102 individuals, half of them drank alcohol in the previous year, of whom 20.5% were at-risk drinkers (≥ 100 g/week). Older people were less often diagnosed with AUD than young-to-middle-aged adults with a similar degree of at-risk drinking. They were less likely to meet the DSM-5 AUD criteria in terms of social and vocational role disruption or creation of a physically hazardous situation. However, at-risk drinking showed a stronger association with subjective psychological distress in older adults, particularly in the near-old group (adjusted odds ratio 1.82, 95% confidence interval 1.09–3.03; p = 0.023).
Conclusions
These findings indicate the importance of screening for mental health problems in older adults, especially near-old adults, who drink more than 100 g of alcohol per week even when they do not satisfy the criteria for a diagnosis of AUD.
