Lifestyle change program engagement in real-world clinical practice: a mixed-methods analysis.

Engaging in a structured lifestyle change program (LCP) is essential to learn healthy behaviors, however, it is not well understood. This study examined factors associated with program engagement and reasons for program withdrawal at a large healthcare system. Highest LCP engagement was found to be associated to factors potentially related to self-efficacy/motivation including older age, higher initial weight, and prior healthcare utilization. Non-Hispanic Black, history of smoking, and prior diagnosis of depression were found to be negatively associated with LCP engagement. Program withdrawal was related to four themes: competing priorities, perceived program effectiveness, characteristics of the program, and facilitator-related factors. These findings suggest that motivation and self-efficacy are important for behavior change program engagement.
