Abstract
Objective: To test and optimize the feasibility and acceptability of a physical activity (PA) and healthy eating behavior change intervention for obese adults with obesity-related co-morbidities or additional risk factors for co-morbidities. Methods: Open-pilot intervention study using an uncontrolled pre and post design with ongoing measures on intervention acceptability and feasibility. Participants received 5 weekly nurse-led one-hour long group sessions. Acceptability and feasibility were assessed throughout. PA, dietary behavior and weight were measured before and after the intervention. Results: Of 74 consenting participants, 61 (82%) received and 47 (64%) completed the intervention. Average ratings of intervention materials and components by participants ranged between 4.1 and 4.9 out of 5. Average facilitator satisfaction rating was 90% (range 75-100%). The intervention delivery was feasible as indicated by ratings and comments from participants and the facilitator. Participants lost -0.86 kg of weight t(45) = 3.84, p = 0.0001, and increased PA by an additional 1.6 (SD = 2.7) sessions/week, t(31) = -3.3, p = 0.002. No significant dietary differences emerged. Conclusion: The intervention was acceptable to the facilitator and participants and feasible for delivery. Several intervention aspects were further optimized. Practice implications: The current study outlines a PA and dietary behavior change pilot intervention coupled with a systematic and transparent process of intervention optimization.
