Design Prospective cross-sectional study. Setting The study data were collected from two separate oncology outpatient clinics. Participants 116 children with cancer aged 10.07 +/- 3.83 were included in the study. The mean follow-up time after cancer treatment turnover was 36.28 +/- 6.43 months. Primary outcome measures Participation levels were assessed using the Pediatric Outcomes Data Collection Instrument (PODCI) as the primary outcome of this study, and they were categorised by BMI. Results The mean z score was 0.64 +/- 1.12, and the average BMI was 17.76 +/- 3.56. The PODCI global functioning score averaged 80.25 +/- 15.23. There were no significant associations between the global functioning score and age, chemotherapy, or surgery (p>0.05). However, significant relationships were found between the global functioning score and gender, BMI, and radiotherapy (p0.05). Conclusions Survivors experience participation restrictions in daily living activities after completing treatment. Systematic evaluation of feedback received from patients/parents regarding physical function, sports, transfer and participation highlights the importance of BMI in childhood cancer survivors. Addressing these factors is key to achieving better health-related quality of life in functionality and participatory outcomes for survivors.eninfo:eu-repo/semantics/openAccessChild HealthArticle
