Abstract

BACKGROUND Physical activities are important for the development of children and increasing evidence suggests beneficial effects of physical activity promotion during cancer treatment as well. The present study aimed at evaluating the current need of exercise interventions in pediatric cancer patients undergoing acute treatment and identifying risk factors for inactivity. PROCEDURE Data about self-reported physical activity before and during treatment was collected in a cross-sectional design with the physical activity questionnaire from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) in a modified cancer specific version. RESULTS One hundred thirty pediatric cancer patients with various entities were questioned 3.0 ± 1.6 months since diagnosis. Patients' activity levels before diagnosis mainly matched reference values for healthy children in Germany. Reductions during treatment affected all dimensions of daily physical activities and minutes of exercise per week decreased significantly (P < 0.001). Largest reductions of physical activities during treatment were identified for bone tumor patients and in-patient stays. CONCLUSIONS Due to the well known importance of physical activity during childhood and the identified risk of inactivity during cancer treatment, supervised exercise interventions should be implemented into acute treatment phase to enhance activity levels and ensure a continuously support by qualified exercise professionals.
