The prevalence and risk factors of sleep problems in pediatric oncology: its effect on quality of life during and after cancer treatment

This review aims to describe the prevalence, types and risk factors of sleep problems in children undergoing cancer treatment and in childhood cancer survivors. Furthermore, the relation between sleep and quality of life (QoL) was described. In children undergoing treatment sleep problems were more common compared to norms and controls. In survivors results were more inconsistent and in some studies even less sleep problems were reported. In both populations various sleep problems were reported (such as night awakenings, bedtime resistance, and daytime sleepiness). Several demographic, disease and treatment related factors were associated with sleep outcomes. Impaired sleep was associated with poorer physical, psychosocial, and cancer-related QoL. Sleep was assessed with a variety of measurements, all measuring different sleep constructs, limiting the formulation of generalizable conclusions. Therefore, a standardized way to assess sleep in different age categories in pediatric oncology is mandatory.
