title: Correlates of sleep behavior among hemodialysis patients. The kidney outcomes prediction and evaluation (KOPE) study.
abstract: BACKGROUND
  Given the importance of sleep to overall physical and mental well-being, we sought to identify the correlates of seven sleep disturbances in a cross-sectional study of a biracial population of male and female patients treated with hemodialysis.
  
  
  METHODS
  Univariate and multivariate analyses of a cohort study of adult patients with end-stage renal disease. Demographic, psychosocial, clinical, and health and physical functioning variables were included.
  
  
  RESULTS
  Waking up during the night (57%) and waking up too early (55%) were the most commonly reported sleep problems. Multivariate analyses consistently indicated that levels of pain, depressive symptoms, and physical functioning were consistently associated with the seven sleep disturbances.
  
  
  CONCLUSIONS
  Sleep disturbances are common in patients with end-stage renal disease. Physical and mental well-being were consistently related to the seven sleep disturbances.
