Background

Loneliness is a common source of distress, suffering, and impaired quality of life in older persons. We examined the relationship between loneliness, functional decline, and death in adults older than 60 years in the United States.

Methods

This is a longitudinal cohort study of 1604 participants in the psychosocial module of the Health and Retirement Study, a nationally representative study of older persons. Baseline assessment was in 2002 and follow-up assessments occurred every 2 years until 2008. Subjects were asked if they (1) feel left out, (2) feel isolated, or (3) lack companionship. Subjects were categorized as not lonely if they responded hardly ever to all 3 questions and lonely if they responded some of the time or often to any of the 3 questions. The primary outcomes were time to death over 6 years and functional decline over 6 years on the following 4 measures: difficulty on an increased number of activities of daily living (ADL), difficulty in an increased number of upper extremity tasks, decline in mobility, or increased difficulty in stair climbing. Multivariate analyses adjusted for demographic variables, socioeconomic status, living situation, depression, and various medical conditions.

Results

The mean age of subjects was 71 years. Fifty-nine percent were women; 81% were white, 11%, black, and 6%, Hispanic; and 18% lived alone. Among the elderly participants, 43% reported feeling lonely. Loneliness was associated with all outcome measures. Lonely subjects were more likely to experience decline in ADL (24.8% vs 12.5%; adjusted risk ratio [RR], 1.59; 95% CI, 1.23-2.07); develop difficulties with upper extremity tasks (41.5% vs 28.3%; adjusted RR, 1.28; 95% CI, 1.08-1.52); experience decline in mobility (38.1% vs 29.4%; adjusted RR, 1.18; 95% CI, 0.99-1.41); or experience difficulty in climbing (40.8% vs 27.9%; adjusted RR, 1.31; 95% CI, 1.10-1.57). Loneliness was associated with an increased risk of death (22.8% vs 14.2%; adjusted HR, 1.45; 95% CI, 1.11-1.88).

Conclusion

Among participants who were older than 60 years, loneliness was a predictor of functional decline and death.

Background and objectives

Homebound older adults and their caregivers have not historically been engaged as advisors in patient-centered outcomes research. This study aimed to understand the attitudes of homebound older adults and their caregivers toward research and participation as research advisors.

Research design and methods

Descriptive thematic analysis of semistructured interviews conducted with 30 homebound older adults and caregivers recruited from home-based medical care practices. Interview questions addressed opinions on research and preferences for engaging as research advisors.

Results

Of 30 participants, 22 were female, 17 were people of color, and 11 had Medicaid. Two themes emerged related to perceptions of research overall: (a) utility of research and (b) relevance of research. Overall, participants reported positive attitudes toward research and felt that research could affect people like them. Three themes emerged related to participating as research advisors: (a) motivators, (b) barriers, and (c) preferences. Participants were open to engaging in a variety of activities as research advisors. Most participants were motivated by helping others. Common barriers included time constraints and caregiving responsibilities, and physical barriers for homebound individuals. Participants also reported fears such as lacking the skills or expertise to contribute as advisors. Many were willing to participate if these barriers were accommodated and shared their communication preferences.

Discussion and implications

Diverse homebound older adults and caregivers are willing to be engaged as research advisors and provided information to inform future engagement strategies. Findings can inform efforts to meet new age-inclusive requirements of the National Institutes of Health.
