Summary
Elderly patients with depression experienced higher mortality rates compared to controls. This increased risk persisted even when physical illness was accounted for, indicating depression
Area of Science:
- Geriatric Medicine
- Psychiatry
- Epidemiology
Background:
- Depression is prevalent in elderly populations.
- The relationship between depression, physical illness, and mortality in older adults requires further investigation.
Purpose of the Study:
- To examine the association between physical illness at referral and 4-year mortality in elderly patients diagnosed with depression.
- To compare mortality rates between depressed elderly patients and age/sex-matched controls.
Main Methods:
- A cohort of elderly patients with depression was compared to age/sex-matched controls.
- Physical health status was assessed at the initial interview.
- Mortality data was collected over a 4-year period.
Main Results:
- Depressed elderly patients presented with poorer physical health at baseline compared to controls.
- The 4-year mortality rate was significantly higher in the depressed group.
- Even after controlling for physical illness, depressed patients, especially men, exhibited significantly higher mortality.
Conclusions:
- Depression in the elderly is associated with increased mortality.
- The higher mortality risk in depressed elderly individuals is not solely attributable to physical health status.
- Depression itself may be an independent risk factor for mortality in older adults.
