Correlates of Depressive Symptoms among Homebound and Semi-Homebound Older Adults.

This study aimed to provide a national profile of homebound and semi-homebound older adults with depressive symptoms and to compare risk factors of depressive symptoms by homebound status. A sample of 1,885 homebound and semi-homebound older adults was selected from Round 1 of the National Health and Aging Trends Study (NHATS). The prevalence of depressive symptoms was 43.9% in homebound older adults and 28.1% in semi-homebound older adults, representing over 830,000 and 1.4 million individuals in the population, respectively. Nearly two-thirds of homebound and over half of semi-homebound older adults with clinically significant depressive symptoms also had significant anxiety symptoms. Results from logistic regression showed that younger age, certain medical morbidities, severity of functional limitations, and pain were common risk factors for depressive symptoms among homebound and semi-homebound older adults. Some differences in the risk factor profile emerged between the homebound and the semi-homebound populations. Alleviating the burden of depression in the semi-homebound population may focus on early prevention that considers the diversity of this population. Home-based, integrated programs of health and mental health services that simultaneously address the medical, psychiatric, and neurologic comorbidities and disabilities of homebound older adults are needed to meet the complex needs of this population.
