Does social support buffer functional decline in elderly patients with unipolar depression?

OBJECTIVE: This study tested whether social support protects against functional decline, either generally or selectively, in the most severely depressed elderly patients undergoing treatment for major depressive disorder. METHOD: In a prospective cohort study design, 113 patients with incident and prevalent unipolar depression were followed for 12 months while they were undergoing naturalistic treatment. Outcome measures included performance on basic and instrumental activities of daily living; predictor variables included Hamilton Depression Rating Scale scores and four domains of informal social support. The analysis employed multivariable ordinary least squares regression models. RESULTS: Improved scores on instrumental activities of daily living and stable scores on basic activities of daily living characterized the subjects. In adjusted analyses, instrumental social support provided marginal protection against worsening performance on instrumental activities of daily living, which were primarily a function of baseline depression severity. Large social networks, more frequent social interaction, and the perceived adequacy of social support played a modest buffering role against declines in performance on basic activities of daily living among the most depressed elderly patients. CONCLUSIONS: Instrumental support was generally protective against worsening performance on instrumental abilities of daily living among elderly patients with recurrent unipolar depression. Subjective and structural dimensions of social support protected the most severely depressed elderly patients against the loss of basic maintenance abilities.

Preference for place of death in a continuing care retirement community.

PURPOSE: To describe death-related planning and preferences for place of death among well elders in a community characterized by a low rate of hospital deaths. DESIGN AND METHODS: Cross-sectional prevalence survey of independent-living residents (n = 219) of a continuing-care retirement community (CCRC) in Central North Carolina characterized by a low rate of hospital deaths. RESULTS: Death-related planning played a part in the decision of 40% of residents to move to the CCRC. A majority of residents reported a clear preference for place of death, and a majority of these preferred to die on the CCRC campus. Most residents wanted to discuss their preferences for place of death with their health care provider. Preferences for place of death appear consistent across age cohorts and are relevant to elders' long-term care decisions. IMPLICATIONS: Given the striking discrepancy between patients' preferences for nonhospital deaths and the high prevalence of hospital deaths in the United States, this often-neglected issue should be routinely addressed in end-of-life planning. The CCRC may be a practice model that is particularly compatible with personal preferences for place of death.

Does private religious activity prolong survival? A six-year follow-up study of 3,851 older adults.

BACKGROUND: Previous studies have linked higher religious attendance and longer survival. In this study, we examine the relationship between survival and private religious activity. METHODS: A probability sample of elderly community-dwelling adults in North Carolina was assembled in 1986 and followed for 6 years. Level of participation in private religious activities such as prayer, meditation, or Bible study was assessed by self-report at baseline, along with a wide variety of sociodemographic and health variables. The main outcome was time (days) to death or censoring. RESULTS: During a median 6.3-year follow-up period, 1,137 subjects (29.5%) died. Those reporting rarely to never participating in private religious activity had an increased relative hazard of dying over more frequent participants, but this hazard did not remain significant for the sample as a whole after adjustment for demographic and health variables. When the sample was divided into activity of daily living (ADL) impaired and unimpaired, the effect did not remain significant for the ADL impaired group after controlling for demographic variables (hazard ratio [RH] 1.11, 95% confidence interval [CI] 0.91-1.35). However, the increased hazard remained significant for the ADL unimpaired group even after controlling for demographic and health variables (RH 1.63, 95% CI 1.20-2.21), and this effect persisted despite controlling for numerous explanatory variables including health practices, social support, and other religious practices (RH 1.47, 95% CI 1.07-2.03). CONCLUSIONS: Older adults who participate in private religious activity before the onset of ADL impairment appear to have a survival advantage over those who do not.

Social correlates of the dimensions of depression in the elderly.

Few investigations of the social correlates of depressive symptomatology have addressed variation in the correlates across multiple dimensions of depression scales. We examined the relationships of selected social, clinical, and demographic correlates with four dimensions of the Center for Epidemiologic Studies-Depression (CES-D) scale in 3,401 community-dwelling elders in the Piedmont area of North Carolina. These correlates explained significant variation in somatic complaints and depressed affect; effects of chronic disability and recent negative events were particularly robust. Having a confidant explained reduced symptomatology for all four dimensions, but particularly for low positive affect and interpersonal problems. Positive affect was also buttressed by helping others. These patterns have particular relevance where treatment for depression is divorced from considerations of the social environment of the elderly patient.

Psychosocial and physical correlates of chronic depression.

This study used a case-control design to address differences in psychosocial, physical and clinical profiles between subjects who presented with a chronic index episode of major depression and those who presented with a non-chronic index episode. Subjects were adult patients participating in the Duke University Mental Health Clinical Research Center (MHCRC) for the Study of Depression in Later Life. Cases (N = 88) who reported duration of depressive symptoms lasting > or = 24 months at enrollment were compared to controls (N = 354) who reported symptoms lasting 1-12 months. The groups were compared with respect to selected demographic and clinical variables, physical function deficits, medical comorbidity, social support constructs and number of recent stressful life events. Social support and physical health were more relevant to chronicity of major depressive illness than were severity of illness or family history. Older age (> 60 years) intensified the deleterious effect of recent negative life events and reduced the deleterious effect of functional impairment on chronic major depression. These findings require special emphasis where treatment for chronic major depression is divorced from considerations of the social environment and functional capacity.
