Obesity, Weight Loss
Conditions
Brief summary
This study is a 24-week, single-arm trial investigating the feasibility of a flipped classroom behavioral intervention for weight management. The investigators will recruit up to 30 adults ages 18+ with a body mass index greater than or equal to 25 kg/m2 to participate in weekly, 1-hour group weight management education delivered remotely via Zoom with a trained health educator. Participants will receive a dietary prescription of 1200-1500 calories/day (5 portion-controlled meals and 5+ servings of fruits and vegetables) and exercise prescription of 150-300 minutes exercise/week. Additionally, participants will be asked to self-monitor diet and exercise adherence weekly. Feasibility outcomes will be collected at baseline, 12-weeks, and 24-weeks.
Interventions
BEHAVIORALFlipped Classroom
The flipped classroom educational model requires participants to independently review educational material before class, and class time with the health educator is spent engaging in group and individual skills-based activities and problem-solving assignments. The theoretical basis for the development of active learning is to elicit higher cognitive learning, according to the revised Bloom's taxonomy and shift independent student time to passive learning (remembering and understanding) and collaborative student and educator time to active learning (applying, analyzing, evaluating, and creating). Thus, the weight management education will include: case vignettes, group debates/discussions, think-pair-share activities, gamification of health-related topics, creation of meal and physical activity, problem-solving barriers to a healthy diet and physical activity, and hands-on worksheets.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Attendance | 24 weeks | Attendance to the group education sessions will be measured weekly and evaluated by the health educator. Attendance records will be entered into the study REDCap database. |
| Attrition | 24 weeks | Attrition rate will be measured at the end of the intervention measured as the percent of participants who completed all 24 weeks of the weight loss program. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Body Mass Index | 24 weeks | Body Mass Index will be calculated as weight (kg) divided by height (cm) squared. |
| Weight | 24 weeks | Participants will be weighed at the outpatient weight management clinic in a private room by a registered nurse prior to the participant seeing a clinic physician. Weight will be collected to the nearest 0.1 kg. |
| Exercise Adherence | 24 weeks | Adherence to the diet and exercise prescription will be measured weekly via participant self-report. Participants will report daily minutes of exercise and steps taken. The self-monitoring sheet will be submitted via email to the health educator prior to each group session. The health educator will provide individual feedback based on self-reported adherence. |
| Diet Adherence | 24 weeks | Adherence to the diet prescription will be measured weekly via participant self-report. Participants will report daily total number of shakes, number of entrees, servings of fruit and vegetables, and days off plan. The self-monitoring sheet will be submitted via email to the health educator prior to each group session. The health educator will provide individual feedback based on self-reported adherence. |
| Height | 24 weeks | Participant height will be measured at the outpatient weight management clinic in a private room by a registered nurse prior to the participant seeing a clinic physician. Standing height will be measured using a stadiometer and collected to the nearest 1 cm. |
