Understanding Physical Activity and Quality of Life in Children and Young People with Chronic Kidney Disease

The aim of this research is to document and evaluate the relationship between physical activity patterns and behaviours and psychosocial outcomes in children and young people with CKD. A second aim is to explore through qualitative methods contextual factors that may explain the type, direction and nature of relationships identified in the quantitative phase. This research will be conducted in multiple phases to maximise recruitment. 1. Phase 1 consists of a battery of in-person physical functioning tests. 2. Phase 2 consists of an online survey of validated questionnaires. 3. Phase 3 consists of online or in-person interviews with CYP Participants recruited through NHS Scotland will take part in all 3 phases. Only Phase 2 (online survey) will additionally be disseminated through patient organisations across the UK to maximise recruitment. In phase 1, participants will take part in a battery of physical activity functioning assessments including multistage bleep tests, sit-up tests, and handgrip tests. Participants will also be given an accelerometer measure to track movements over 7 days. Participants taking part in this phase will also complete the phase 2 online survey which includes a physical activity, Quality of life, Fatigue, Strength and Difficulties, and Mental health questionnaire. In phase 3, participants from phase 1 will return and take part in an interview to gain deeper insights into psychosocial influences and limitations in engaging in physical activity as well as gaining a better understanding of the impact of CKD on psychosocial wellbeing.
