7-hour sleepers have highest health-related quality of life; lower QoL seen with shorter, longer sleep
THURSDAY, May 3, 2018 (HealthDay News) — Sleep duration is associated with health-related quality of life among patients with chronic kidney disease (CKD), according to a study published online May 3 in the Clinical Journal of the American Society of Nephrology.
Su-Ah Sung, M.D., from Eulji General Hospital in Seoul, South Korea, and colleagues analyzed data from 1,910 adults with predialysis CKD participating in the Korean Cohort Study for Outcome in Patients with CKD. The Short Form-36 Health Survey was used to evaluate health-related quality of life.
The researchers found that seven-hour sleepers had the highest health-related quality of life. There was an inverted U-shaped relationship between sleep duration and health-related quality of life. After multivariable logistic analysis, compared with seven-hour sleepers, short sleepers (≤5 hours/day) had lower health-related quality of life (odds ratios [ORs], 3.23 for the physical component summary and 2.37 for the mental component summary), as did long sleepers (≥9 hours/day) (ORs, 2.8 for the physical component summary and 2.08 for the mental component summary).
“These findings suggest that short or long sleep duration is independently associated with low health-related quality of life in adults with CKD,” the authors write.
