About

This single-arm proof-of-concept pilot will assess the feasibility and acceptability of integrating a survivorship nutrition intervention (BfedBwell) into an existing clinical exercise oncology program (BfitBwell).

Full description

Individuals with experience in delivery of lifestyle (e.g., diet, physical activity) interventions will be recruited to deliver and evaluate the integrated BfedBwell + BfitBwell intervention.

Cancer survivors with overweight/obesity who have completed active treatment will be recruited from the University of Colorado Anschutz Medical Campus for participation in a 12-week single-arm study of the integrated BfedBwell + BfitBwell intervention. Feasibility and acceptability will be evaluated. Exploration of intervention effect on adherence to cancer survivorship guidelines, body composition, and cardiometabolic indicators of health will be used to evaluate proof-of-concept prior to advancing to efficacy testing.

11. Uncontrolled hypertension, defined as diastolic blood pressure >100 mmHg, systolic blood pressure >160 mmHg, or resting heart rate >100 bpm as measured in duplicate on the screening visit after 5 minutes of rest in a seated position (if screening is needed due to lack of updated medical record within previous 12 months)

12. Diabetes (history of type 1 or type 2 diabetes, hemoglobin A1c >7.5%, or fasting glucose ≥126 mg/dL as measured during the screening visit if screening is needed due to lack of updated medical record within previous 12 months) unless well controlled on metformin alone
