Race and restless sleep complaint in older chronic dialysis patients and nondialysis community controls

There is mixed evidence about the relation of race to risk of sleep disturbance. We explored the relation of race to restless sleep complaint in survey data from a cohort of 311 older patients undergoing chronic renal dialysis and a similarly aged cohort of 354 nondialysis controls. Older dialysis patients were significantly more likely to report restless sleep. Restless sleep complaint was related to comorbidity, depressed mood, use of sleep medications, and perceived health status in both groups. Black patients in the dialysis cohort had decreased odds of restless sleep, but Black and White controls did not differ significantly in reporting restless sleep. Compared with their more socially advantaged White counterparts, older Black dialysis patients may perceive the chronic dialysis care environment more favorably. The findings are consistent with the view that sleep quality in late life is likely to reflect a delicate balance between psychological as well as physical well-being.
