An Investigation Into the Relationship Between Dietary Intake and Health-related Quality of Life in Children and Young People With Juvenile Idiopathic Arthritis

"Physical activity and diet in children and young people with arthritis" A qualitative study of exploring stake holder's experiences.

Juvenile Idiopathic Arthritis (JIA) is the most common type of arthritis in children under the age of 16. The disease and its therapeutic management can cause serious long-term complications, which affect general activities and quality of life. The lack of specific guidelines for safe physical activity and appropriate management of any nutritional deficit aiming our study to find out your views and opinions about the needs of children and young people with juvenile idiopathic arthritis. We want to improve our knowledge about the impact of physical activity and eating habit on juvenile idiopathic arthritis and we want to develop a tool to help evaluate care. Few studies targeting quality of life and wellbeing in children adolescent populations have adopted the diet and physical activity perspective or approaches, consequently, this research project will help to address this gap through:

1. Interview: to look at young people's current experiences with JIA as well as their parents/caregivers and health care professionals. Study findings will provide a snapshot of the current experiences of participants, helping to improve our knowledge about JIA, physical activity, and diet. Qualitative studies exploring people perspectives on their experiences, when collected systematically, adds valuable depth, insight and understanding into the issues related to JIA not possible through quantitative methodologies. This study uses a qualitative approach known as framework methodology to understand stakeholder's experience of what helps and what hinders improving the quality of life in children and young adult with JIA. 21-30 stakeholders will be recruited in Oxford UK, to take part in individual semi-structured guided interviews lasting approximately one hour. Participant responses will be transcribed by the chief investigator and analysed to extract themes that will answer the research question.
2. Delphi study: which aims to develop a diet and physical activity intervention for children and young adult with JIA.

3. Delphi study: which aims to develop diet and physical activity intervention for children and young adult with JIA.

This protocol covers the second and third approaches only (interview and Delphi).
