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.

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
01:27Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
01:11Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
