Created to take advantage of: – The opportunity to gain new knowledge about the long‐
term effects of cancer and therapy, knowledge that can be used to help design treatment protocols and
intervention strategies that will increase survival and minimize harmful health effects.
– The obligation to educate survivors about the potential impacts of cancer diagnosis and treatment on their
health, and to provide follow‐up care, for example, by treating and implementing programs for the prevention
and early detection of late effects.

Survivor Reported Barriers to Exercise
• Too tired• Too busy• Do not belong to a gym• Rather watch television
or read• No one to exercise with• Bad weather• Feel self‐conscious• Do not enjoy it
• Friends do not exercise• No willpower• No access to equipment• Worry about injury• Do not like to sweat• No support• Do not want to be sore• Unsure how to exercise• No place to exercise

Survivor reported barriers to adopting a healthy diet
To eating more fruits/vegetables
• Hard to get when dining out
• Do not like the taste• Not available at home• Cost too much• Take too long to prepare• Hurt stomach• Friends do not eat them• Family does not like them
To eating more whole grains
• Hard to get when dining out
• Do not like the taste• Family does not like them• Not available at home• Friends do not eat them• Cost too much• Take too long to prepare• Hurt stomach

To limiting high‐fat foods• Commercials make high‐fat foods
tempting• Hard to get low‐fat foods when
dining out• Friends eat a lot of high‐fat foods• Family eats a lot of high‐fat foods• Low‐fat foods do not taste good• No willpower• Low‐fat foods do not fill me up• Do not know how to choose
lower‐fat foods• Low‐fat foods not available at

Summary• There are increasing numbers of childhood
cancer survivors
• Childhood cancer survivors have altered body composition
• They are inactive
• They are at increased risk for cardiac disease and early death
• Cranial radiation, amputation, female gender, and black race contribute to a poor outcome
Summary
• Altered body composition and inactivity are correlated
• Social correlates include lower income and lower educational attainment
• Smoking is associated with inactivity
• Dietary habits appear to be sub‐optimal
Summary
• Interventions are beginning to emerge
• There are problems with intervention participation and retention
• Additional work is needed that addresses the unique physical and cognitive needs of cancer survivors
• Perceived barriers to change need to be considered when designing interventions
• The interventions need to be portable
Childhood Cancer Survivor Study
•
The Childhood Cancer Survivor Study is an NCI‐ funded resource (U24 CA55727) to promote and
facilitate research among long‐term survivors of cancer diagnosed during childhood and
adolescence.
•
