Cancer Survivorship, Obesity, Overweight
Conditions
Brief summary
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).
Detailed 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.
Interventions
Group-based education and discussion (60 minutes each per week, virtual and in-person) based upon guidelines for nutrition for cancer survivorship (e.g., follow a plant-based diet with a variety of vegetables, fruits, whole grains, and legumes; limit alcohol intake; reduce consumption of highly processed foods and foods high in salt; achieve a weekly calorie deficit of approximately 3500 kcal for weight loss)
Individual 1:1 counseling sessions (30 minutes each per month, virtual) with an RD to review progress and address barriers
Group-based behavioral skills development sessions and cooking demonstrations (60-90 minutes each per month, in-person) to focus on behavior change techniques (e.g., self-monitoring, goal setting) and nutrition skills (e.g., recipe development, label reading).
This program consists of a supervised exercise program developed by a cancer exercise specialist and based upon the NCCN guidelines for physical activity during cancer survivorship and other recommendations.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Determine the research protocol recruitment feasibility of the BfedBwell nutrition intervention | 12 weeks | Recruitment will be assessed as the number of adults screened and the proportion of eligible screens who enroll. |
| Determine the research protocol adherence feasibility of the BfedBwell nutrition intervention | 12 weeks | Adherence will be assessed as \[# sessions attended/# sessions provided\] |
| Determine the research protocol outcome assessment feasibility of the BfedBwell nutrition intervention | 12 weeks | Outcome assessment rates will be assessed as \[# completing assessments/# enrolled\]. |
| Determine the research protocol retention feasibility of the BfedBwell nutrition intervention | 12 weeks | Retention will be assessed as \[# of participants who complete the 12-week intervention/# of participants enrolled\]. |
| Determine the intervention feasibility by program delivery staff using Feasibility of Intervention Measure (FIM) | 12 weeks | Upon completion of the intervention, program delivery staff will be asked to complete the Feasibility of Intervention Measure (FIM). A Likert scale from 1 (completely disagree) to 5 (completely agree) is used for each question; higher scores indicate greater intervention feasibility. |
| Determine the intervention acceptability by program delivery staff using Acceptability of Intervention Measure (AIM) | 12 weeks | Upon completion of the intervention, program delivery staff will be asked to complete the Acceptability of Intervention Measure (AIM). A Likert scale from 1 (completely disagree) to 5 (completely agree) is used for each question; higher scores indicate greater intervention acceptability. |
| Determine the intervention acceptability by program delivery staff using Intervention Appropriateness Measure (IAM) | 12 weeks | Upon completion of the intervention, program delivery staff will be asked to complete the Intervention Appropriateness Measure (IAM). A Likert scale from 1 (completely disagree) to 5 (completely agree) is used for each question; higher scores indicate greater intervention appropriateness. |
| Determine the intervention acceptability by participants using the Net Promoter Score (NPS) | 12 weeks | Participants will be asked to complete weekly ratings using the Net Promoter Score (NPS). Respondents are grouped as follows: 1) promoters (score 9-10) are loyal enthusiasts who will keep referring others and fueling growth, 2) passives (score 7-8) are satisfied but unenthusiastic customers who are vulnerable to competitive offerings, and 3) detractors (score 0-6) are unhappy customers who can impede growth with negative word-of-mouth. The final NPS score is calculated as % promoters - % detractors. NPS scores range from -100 to +100, with scores \>0 indicating good acceptability. |
| Determine the intervention acceptability by participants and program providers during qualitative interviews | 12 weeks | 1:1 interviews will be conducted with all program delivery staff and BfedBwell survivorship nutrition intervention participants after the 12-week intervention to assess acceptability of intervention and provide feedback for continued refinement. |
