Associations between sleep problems and cardiometabolic risk in maintenance hemodialysis patients: A multicenter...

Area of Science:

• Nephrology
• Cardiology
• Sleep Medicine

Background:

• Cardiovascular disease (CVD) is a leading cause of mortality in chronic kidney disease (CKD) patients.
• Identifying cardiometabolic risk factors early is crucial for this population.
• Sleep disturbances are emerging as significant risk factors for cardiometabolic health.

Purpose of the Study:

• To investigate the association between sleep problems and cardiometabolic risk in hemodialysis (HD) patients.
• To explore the relationship between sleep duration, sleep quality, and specific cardiometabolic risk factors.

Main Methods:

• A multicenter study involving 3025 hemodialysis patients.
• Binary logistic regression models were used to analyze the data after adjusting for confounders.
• Sleep duration (categorized as >7h and <7h) and sleep quality were assessed.

Main Results:

• Hemodialysis patients sleeping >7h had increased odds of hypertension, hyperglycemia, hypertriglyceridemia, and hypercholesterolemia.
• Patients sleeping <7h showed higher odds of hypertriglyceridemia and hypercholesterolemia, but decreased risks for hyperglycemia and low HDL-cholesterol.
• Poor sleep quality correlated negatively with low HDL-cholesterol and hypertriglyceridemia, with gender-based differences observed.

Conclusions:

• Sleep duration and quality are significantly associated with cardiometabolic risk factors in hemodialysis patients.
• Both prolonged and insufficient sleep, as well as poor sleep quality, present distinct risks.
• Understanding these sleep-related associations can inform targeted interventions for cardiovascular risk management in CKD patients.
