Feasibility and acceptability of a parent-child intervention to improve step count in childhood cancer survivors exposed to cardiotoxic therapy: The STEP UP for FAMILIES Study.

Background: Late morbidity after childhood cancer may be mitigated by healthy lifestyle behaviors. We piloted a game-based, parent-child digital intervention to increase activity in sedentary survivors.

Methods: Survivors aged 10-16 treated with cardiotoxic therapy and not meeting US physical activity guidelines were enrolled in a single-arm study with a parent.
