Summary
Major depression prevalence increases with age, affecting 13% of 85-year-olds. It is more common in institutionalized elderly patients with health issues.
Area of Science:
- Gerontology
- Psychiatry
- Epidemiology
Background:
- Major depression is a significant health concern in older adults.
- Understanding its prevalence and associated factors is crucial for effective interventions.
Purpose of the Study:
- To estimate the prevalence of major depression in elderly cohorts aged 75, 80, and 85.
- To identify features associated with major depression in these age groups.
Main Methods:
- A clinical examination was conducted on 651 individuals across three age cohorts.
- Major depression was diagnosed using DSM-III criteria.
- Prevalence was compared between institutionalized and community-dwelling individuals.
Main Results:
- Prevalence of major depression increased with age, reaching 13% in the 85-year-old cohort.
- Institutionalized patients had a fourfold higher frequency of depression (16%) compared to those living at home (4%).
- Depression was strongly associated with poor objective health, intellectual functioning, functional capacity, vision impairment, urinary incontinence, Parkinson's disease, and other chronic conditions.
Conclusions:
- Major depression is relatively rare in healthy elderly individuals but common among disabled, institutionalized older adults.
- Age, institutionalization, and specific health conditions are significant risk factors for major depression in the elderly.
