Abstract

Objective: To explore the association between sleep duration and death from chronic kidney disease in the general Japanese population.

Methods: We conducted an 19.3-year follow-up study of 40,272 men and 54,902 women aged 40-79years and free of renal disease, cardiovascular disease and cancer in the Japan Collaborative Cohort Study for Evaluation of Cancer Risk at baseline (between 1986 and 1990). Sleep duration was categorized into five groups: <6, 6 to <7, 7 to <8, 8 to <9, and ≥9 hours per day. Cox proportional hazard models were used to analyze the association between sleep duration and death from chronic kidney disease.

Results: Compared with persons with 7 to <8 hours sleep duration, those who slept 8 to <9 hours (HR: 1.41, 95% CI: 1.05-1.88) or ≥9hours (HR: 1.82, 95% CI: 1.28-2.58) per day had a higher risk of developing chronic kidney disease mortality. This association was particularly pronounced in individuals aged younger than 65years.

Conclusions: Sleep duration of 8 or more hours per day was associated with increased risk of chronic kidney disease mortality in the general Japanese population.
