Endocrine and Metabolic Disorders in Survivors of Childhood Cancers and Health-Related Quality of Life and Physical Activity (original) (raw)

Context: Childhood cancer survivors experience chronic health conditions that impact healthrelated quality of life (HRQOL) and participation in optimal physical activity. Objective: The study aimed to determine independent effects of endocrine and metabolic disorders on HRQOL and physical activity. Design, Setting, and Patients: Retrospective cohort with longitudinal follow-up of survivors of childhood cancer enrolled in the North American Childhood Cancer Survivor Study. Main Outcome Measures: Medical Outcomes Short Form-36 estimated HRQOL, and participation in physical activity was dichotomized as meeting or not meeting recommendations from the Centers for Disease Control and Prevention. Log binomial regression evaluated the association of each endocrine/metabolic disorder with HRQOL scales and physical activity. Results: Of 7287 survivors, with a median age of 32 years (range, 18 to 54 years) at their last followup survey, 4884 (67%) reported one or more endocrine/metabolic disorders. Survivors with either disorder were significantly more likely to be male, older, have received radiation treatment, and have experienced other chronic health conditions. After controlling for covariates, survivors with any endocrine/metabolic disorder were more likely to report poor physical function risk ratio (RR,
