Sleep as a Predictor of Health-Related Quality of Life among Economically Disadvantaged Black Older Adults.

OBJECTIVES

Sleep disturbances may partially account for the health-related quality of life (HRQoL) disparities experienced by Black older adults when compared to non-Hispanic White (NHW) adults. The present study examined the role of self-reported sleep duration and the belief that one is not getting enough sleep on physical and mental HRQoL among Black older adults.

DESIGN

Participants were 281 community-dwelling, economically disadvantaged Black older adults between 60 and 97 years of age (Mean=69.01, SD=6.97) who lived in a large city in the Southeastern United States. The present study uses baseline data from a larger intervention study aimed at promoting social connection and food security among older adults. For this study (and as part of the larger intervention), participants completed an assessment battery that included (1) a demographic data and health questionnaire that included self-reported sleep duration and a belief that one is not getting enough sleep questions; (2) the CDC (Centers for Disease Control and Prevention) Health-Related Quality of Life-14 Healthy Days Core Module; and (3) the World Health Organization Quality of Life-Brief Form.

RESULTS

Descriptive results show that most participants slept less than 7 hours and felt like they did not get enough sleep. Results from 2 hierarchical regressions also showed that believing one is not getting enough sleep predicts lower self-reported mental and physical HRQoL.

CONCLUSION

While sleep deprivation has a serious impact on quality of life for Black older adults, sleep disturbances in this population are understudied. Interventions to improve sleep duration and quality among Black older adults may help reduce disparities in quality of life between Black older adults and NHW adults.
