Experiences of children with obesity and their parents of participating in a physical activity on prescription intervention: a qualitative study.

Introduction: The prevalence of childhood overweight and obesity has increased substantially in recent decades. Physical activity is a key component in improving metabolic and overall health in children with obesity. The Swedish Physical Activity on Prescription (PAP) is an established method for promoting physical activity, yet knowledge regarding its applicability and acceptability in paediatric populations is scarce. This study explored children's and parents' experiences of PAP, including perceived barriers, facilitators, and any changes in physical activity behaviour. Methods: Twenty-two children and parents were purposively recruited from a previous intervention study at paediatric and rehabilitation clinics in Region Västra Götaland, Sweden. Semi-structured, in-depth interviews were conducted at locations chosen by participants, audio-recorded, and transcribed verbatim. Data were analysed using inductive qualitative content analysis, including coding, categorisation, and development of an overarching theme. Researcher triangulation was applied throughout the analytical process to strengthen credibility. Results: The analysis resulted in the main theme Discussion: The findings suggest that children with obesity and their parents experience PAP as a supportive, person-centred, intervention extending across healthcare, everyday life, and organised sports. The intervention was perceived as combining conversational guidance with shared responsibility, with engagement facilitated by fun, tailored activities aligned with family routines, while financial and practical barriers could limit participation. Overall, the findings suggest that individually adapted, family-inclusive PAP is a feasible and acceptable strategy in Swedish paediatric obesity care, with potential broader benefits for children's health and well-being.
