Abstract

Abstract: INTRODUCTION: Adult survivors of pediatric central nervous system (CNS) tumors are at the highest risk for morbidity and late mortality among all childhood cancers – owed in part to chronic health condition burden, which intersects with environmental and lifestyle factors. Their weight epidemiology has not been previously characterized. METHODS: An institutional, cross-sectional study was carried out amongst young adults ages 18-39 years, previously treated for pediatric CNS tumors and seen in our specialty survivorship clinic from January 2016 to December 2021. Sociodemographic, clinical, and treatment information was extracted from medical records and summarized by descriptive statistics. Anthropometric information extracted from clinical visit records was used to calculate body mass index (BMI) and weight status category according to CDC guidelines. RESULTS: We identified 200 survivors, 47% male and 53% female. Median age was 26 years (range 18-39); patients were median 16.5 years (range 1.5-34.2) from initial diagnosis. Most common primary diagnoses were low grade-glioma (51.0%) and embryonal tumor (20.5%.) One hundred and five (52.5%) survivors had received prior cranial radiation; 81 (40.5%) had an endocrinologic disorder at time of visit. Amongst the entire cohort, 39% were healthy weight, 5% were underweight, 27% overweight, 21% obese, and 8% severely obese. CONCLUSION: The majority of young adult survivors seen in our clinic were not healthy weight by BMI definition. The distribution of BMI groups appears comparable to contemporary studies of the general young adult U.S. population. For those with decreased muscle mass, a previously recognized issue in pediatric CNS tumor survivors, BMI may underestimate body fat. By abstract presentation, univariable analyses will be performed using the Fisher's exact test or Wilcoxon rank sum test to assess for undernutrition and overnutrition risk factors. Our refined understanding of the nutritional epidemiology in this population will allow for more strategic diet and exercise interventions.
