Exercise perceptions and practices of people receiving peritoneal dialysis: An international cross-sectional survey.

Background: Low physical activity and functional impairment are prevalent and unaddressed in people receiving peritoneal dialysis (PD). Exercise has been shown to improve physical function and mental health for people with kidney disease.

Methods: Cross-sectional descriptive survey aimed at identifying the exercise and physical activity perceptions and practice patterns of people receiving PD. The survey was developed and pretested with persons living with kidney disease, PD clinicians and exercise specialists.

Results: There were 108 respondents (people receiving PD) with the majority from Canada (68%) and the United Kingdom (25%). Seventy-one per cent were engaged in physical activity two or more times per week. Most (91.8%) believed that physical activity is beneficial, and 61.7% reported healthcare provider discussion about physical activity. Perceptions regarding weightlifting restrictions varied: 76% were told not to lift weight with a maximum amount ranging from 2 kg to 45 kg. Few (28%) were instructed to drain PD fluid prior to physical activity. Mixed advice regarding swimming ability was common (44% were told they could swim and 44% were told they should not).

Conclusions: Knowledge gaps suggest that education for both healthcare providers and patients is needed regarding the practice of exercise for people living with PD. Common areas of confusion include the maximum weight a person should lift, whether exercise was safe with or without intrabdominal PD fluid in situ and whether swimming is allowed. Further research is needed to provide patients with evidence-based recommendations rather than defaulting to restricting activity.
