bfedbwell optimization pilot

Conditions: Survivorship; Cancer

Summary: using the multiphase optimization strategy (most) framework, an engineering-based approach to efficiently and systematically develop, optimize, and evaluate behavioral interventions, this study will test three components: (1) 1:1 counseling with a registered dietitian, (2) behavioral skills development, and (3) group support for delivery alongside a core nutrition curriculum within a clinical exercise oncology program.

individuals with experience in delivery of lifestyle (e.g., diet, physical activity) interventions will be recruited to deliver and evaluate the integrated bfedbwell 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 6-month cluster-randomized 2\^3-factorial pilot optimization trial of the bfedbwell 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 determine a set of components that demonstrate patterns of efficacy.
