  1. Exercise in Children: Definitions, Data Harmonization, and Translational Research CC-CHOC KFC Webinar January 30, 2012

  2. While the idea that "exercise is good for children" seems axiomatic, translating this vague notion into specific, biological mechanisms that could be used to actually influence health and hasten the transfer of knowledge from basic discovery to clinical application has proved to be difficult.

  3. Clinical Trials Utilizing VO2max in Children and Adults. • We used PubMed to estimate the number of exercise studies in children whose VO2max is measured.

  4. Substantial obstacles have impeded the development of multicenter trials focused on physical activity outcomes in children: • the lack of well accepted and precise definitions of exercise and physical activity outcome variables in children • mechanisms to support the sharing of exercise-derived data among separate institutions • common protocols for exercise testing and physical activity assessment either in the laboratory or in the field. • The goal of this project is to begin to address these gaps.

  5. SPECIFIC AIMS (Achievable Goals in One Year) • To assemble a working group of translational investigators experienced in pediatric exercise testing and physical activity assessment in health and disease • To identify a key topic in ontology and data harmonization that must be addressed, and begin the process of data harmonization using a specific use-case • To implement a robust plan for multicenter communication (e.g., website, Facebook, Twitter) and plan symposia on this effort for presentation at key national meetings in 2012 • To develop a cohesive strategy for ongoing support with the goal of funding the project for 3-5 years

  7. Data Architecture Project • Pediatric Exercise Ontology Project • White Paper • Pediatric Exercise Medicine Curriculum • Dog and Pony Show • Funding

  8. Examples Why is AcKcal reported in one not the other ? Similarly for SpO2 VO2 units are different HR values are in entirely different range

  9. Issues Units missing/ambiguous Environmental information missing Variable understanding Variable mappings Choice of variables Suspect data values Suspect correlations or data transitions Meaning (less) ness of decimal places Intervals ….

  10. Solutions Documentation/ontology Ontology mappings Best practices Data cleaning tools Statistical error analysis …..

  11. Finding the right words in pediatric exercise….not so simple.

  12. How will we… Keep on Truckin’?

  13. Plan A: To prepare for an NIH RO1 funded multicenter clinical trial: The Fitness Phenotype in Children—An Effective Biomarker for Disease Risk Across the Lifespan • American Academy of Pediatrics recently recommended for the first time that cholesterol screening begin in children. • at the core of this effort is the idea that energy balance (determined in large measure by physical activity output and nutritional intake) could be altered in children to improve health. • lack of definitive biomarkers to quantify the physical activity phenotype (PAP) of children and to link that phenotype with specific early disease risk biomarkers. test hypotheses that will provide clinicians with accessible tools to: • more readily identify lifestyle disease risk in children • implement lifestyle change • gauge the effectiveness of such change in response to therapeutic intervention
