Tonorezos ES, et al. - Researchers estimated the impact of exercise (metabolic equivalent-hours per week⁻¹) on the risk for adverse psychological outcomes among childhood cancer survivors using log-binomial regression and adjusting for cancer diagnosis, treatment, demographics, and baseline conditions. Overall 6,199 participants in the Childhood Cancer Survivor Study (median age, 34.3 years; median age at diagnosis, 10.0 years) were analyzed after completing a questionnaire surveying exercise and medical/psychological conditions. In childhood cancer survivors, findings revealed a correlation between less psychological burden and cognitive impairment with vigorous exercise.
