title: Physical Activity and Sleep Patterns in Hemodialysis Patients in a Suburban Environment.
abstract: OBJECTIVE
  Hemodialysis (HD) patients are less active than their healthy counterparts. They are often plagued with sleep disorders that affect the quality of their sleep. Our aim was to objectively quantify activity and sleep quality among HD patients in a suburban HD population.
  
  
  METHODS
  Activity and sleep parameters were measured using a commercially available activity tracker in 29 HD patients from Baton Rouge, LA, USA. Patients in the feedback group received their activity and sleep data at each dialysis treatment. In addition, questionnaires were administered at the beginning and end of the study period. Patients were stratified based on activity levels and sleep quality.
  
  
  RESULTS
  Patients walked an average of 5,281 steps/day and slept 370.5 min/night. Informing patients about their daily number of steps taken, did not increase activity. Only 3% of the population followed were active, defined as walking more than 10,000 steps per day. Patients walked significantly less on dialysis days compared to the other days of the week. Many of the patients experienced poor sleep quality, with patients in the first shift experiencing the greatest disturbance to their sleep/wake cycle.
  
  
  CONCLUSIONS
  Patients in a suburban environment walked much less than those in a previously studied urban population. They rarely met the recommended goal of 10,000 steps/day, even on non-dialysis days. Interventions to increase physical activity may target any day of the week, particularly HD days. Prospective, long-term studies are needed to evaluate the use of activity trackers in dialysis patients and their impact on physical activity.
