A Culinary-Based Intensive Lifestyle Program for Patients With Obesity
- Conditions
- Obesity
- Interventions
- Behavioral: Teaching Kitchen Collaborative Curriculum
- Registration Number
- NCT04624620
- Lead Sponsor
- Dartmouth-Hitchcock Medical Center
- Brief Summary
The study team proposes in this pilot to test, in a single-arm mixed-methods study, the feasibility, acceptability, and preliminary effectiveness of the 16 modular classes taught by a chef, dietitian, and health coach. While the pilot may not have the power to detect significant change, it will provide preliminary data for a NIH application to further test this curriculum in a pragmatic, community-based, randomized multi-site Teaching Kitchen Collaborative Curriculum (TKCC) study planned for Jan 2022 or thereafter. If effective, the TKCC has potential to impact population health through translation into teaching kitchens nationally and adaptation to clinic /community settings.

Program Feasibility based on Number of withdrawals (dropouts) 16 Weeks Number of enrolled participants officially withdrawing from the study and reason for withdrawal
Program Acceptability based on participant interviews evaluating the pilot and assessing strengths/weaknesses. 16 weeks Program acceptability will be assessed through participant semi-structured participant interviews assessing program strengths/weaknesses.
- Secondary Outcome Measures
Name Time Method Change in TKCC Survey Responses Baseline, 16 Weeks The Teaching Kitchen Collaborative Curriculum (TKCC) survey is an investigator created, non-validated Health Habits Survey that assesses nutrition, exercise, cooking habits, sleep behaviors, basic medical information, readiness to change, mindfulness, and telehealth experience. Individual survey questions have variable response categories (examples: commitment to change) is assessed using a 1 to 10 scale with 1 being a less favorable response, and 10 is a more favorable response.
Change in Body Weight Baseline, 16 weeks, 1 year kg
Change in skeletal muscle mass Baseline, 16 weeks skeletal muscle mass (lbs)
Change in Quality of Life Baseline, 16 Weeks Short Form RAND Survey. Quality of life will be assessed using the 20-item Short Form Survey Instrument (SF-20). It was developed by the RAND corporation. The SF-20 is a well accepted and valid survey used to assess overall health measuring 8 different dimensions including physical and social functionality and limitations, mental health, vitality, pain, general health perception, and health change.
Change in Readiness to Change Baseline, 16 Weeks University Rhode Island Change Assessment Scale (URICA). Self-reported survey of respondents' feelings about changing their weight problem. Total score is also called the Readiness Score, ranging from -2 to +14 (worse to better), calculated by subtracting the mean from the precontemplation responses from the summation of the means of responses to contemplation, action, and the struggling to maintain items.
Change in Hemoglobin A1c Baseline, 16 weeks Hemoglobin A1c mmol/mol
Change in Body Mass Index Baseline, 16 weeks, 1 year Height (cm) and Weight (kg) will be used to calculate body mass index (kg/m\^2)
Change in Percent Body Fat Baseline, 16 weeks Percent Body Fat
Change in Fasting Insulin Baseline, 16 weeks Fasting insulin mg/dl
Change in AST Baseline, 16 weeks Hemoglobin AST mg/dl
Change in Waist Circumference Baseline, 16 weeks Waist circumference will be measured (cm)
Change in Visceral fat area Baseline, 16 weeks Visceral fat area (cm2)
Change in Mindfulness Baseline, 16 Weeks The Mindful Easting Questionnaire (MEQ) is a widely used instrument that assesses trait mindfulness.
Change in Nutrition Baseline, 16 Weeks US PDQS. As measured by participants self-reported eating habits on fruits, vegetables, and other diet habits.Scores associated with the healthier dietary pattern are higher and lower for unhealthy patterns.
Change in Food Insecurity Baseline, 16 Weeks Hunger Vital Signs. 2-questions to assess food insecurity as recommended by the American Academy of Pediatrics:
"We worried whether our food would run out before we got money to buy more." Was that often true, sometimes true, or never true for your household in the last 12 months? "The food we bought just didn't last, and we didn't have money to get more." Was that often true, sometimes true, or never true for your household in the last 12 months? A response of "often true" or "sometimes true" to either question = positive screen for Food Insecurity.Change in Exercise Baseline, 16 Weeks Exercise vital sign: (EVS is calculated by multiplying responses to "On average, how many days per week do you engage in moderate to strenuous exercise (like a brisk walk)?" and 2) "On average, how many minutes per day do you engage in exercise at this level?" in order to display minutes per day of moderate or strenuous exercise.
Change in Fasting glucose Baseline, 16 weeks Fasting glucose mg/dl
Change in Microbiome Baseline, 16 weeks stool samples
Change in ALT Baseline, 16 weeks Hemoglobin ALT mg/dl
