Demographic and medical information
Children’s demographic and medical information was abstracted from their
medical records. This included sex, age, body mass index (BMI), date of
diagnosis, tumor type and tumor location. Any treatment that had taken
place before the time of assessment was collected, including
neurosurgery, start of radiotherapy, and start of chemotherapy, as well
as complications of hydrocephalus and epilepsy. Patients and their
parents provided information on pre-existing sleep problems, use of
sleep medication during the seven day sleep assessment, daytime naps and
whether they slept at home or in the hospital during the assessment.
Lastly, through a general survey, parents provided sociodemographic
information.
