The authors examined the relationship between anxiety, depression and physical disability, after controlling for demographic and health variables, in a sample of 374 adults aged 18-94. Results indicate that anxiety, depression and comorbid anxiety and depression are associated with higher levels of disability, after controlling for factors such as age, gender, income, self-rated health, number of medical conditions and number of physician visits in the past year. Furthermore, anxiety, depression and comorbid anxiety and depression have a differential effect on disability according to age, with older adults with any of these symptoms reporting higher levels of disability than younger adults. These findings suggest that physicians working with older adults should assess for and treat anxiety as well as depressive symptoms.

Prior research has found that disability and apathy are associated with late-life depression. However, the effect of age on these associations in late-life, an ambiguous term encompassing all individuals typically older than 60 years, has not been examined. We investigated the association of depression with disability, apathy and resilience across the age range of late-life. One hundred and five community-dwelling elderly with moderate levels of disability were assessed using the Geriatric Depression Scale (GDS), Hardy-Gill Resilience Scale, Starkstein Apathy Scale and IADL/ADL questionnaire. Multiple regression analysis was used to assess relationships between depression, disability, apathy and resilience, stratified by age (<80 vs. >80). In the <80 year old subject group, resilience, apathy and disability scores (partial type III R2 = 11.1%, 10.4% and 12.8%, respectively) equally contributed to the variability of GDS score. In contrast, in the >80 year old subject group, apathy (partial type III R2 = 18.7%) had the greatest contribution to GDS score. In elderly persons under age 80, resilience, apathy and disability all have relatively equal contributions to depression scores, whereas in those over age 80, depression is most highly correlated with apathy. These data suggest that depressive symptoms in elderly persons have different clinical features along the age spectrum from young-old to old-old.
