Noom Coach for Bariatric Surgery

Overweight and obesity have reached epidemic proportions in the United States As few behavioral treatments are effective for weight loss bariatric surgery is an increasingly important option Although these procedures are more helpful than psychosocial treatments post operative weight losses vary widely and a notable subset of patients demonstrate suboptimal weight loss or substantial weight regain Adherence to treatment recommendations is a likely contributor to these variable outcomes Smartphone applications apps designed to augment behavior change or enhance adherence have expanded exponentially in recent years and are a potentially useful option to improve outcomes but rigorous research on apps is limited and high quality adequately powered randomized controlled trials with large samples are required This Fast Track study Phase I II application will test a combined smartphone app and health coaching system to improve adherence and behavioral psychosocial outcomes for patients receiving bariatric surgery Specifically Phase I will utilize a small pre surgery randomized trial n of a coach led mobile application for bariatric candidates Noom Coach for Bariatric Health to establish the initial efficacy of this app by comparing the use of weeks of use n to standard pre surgery treatment n This phase will establish within subject effects for change in diet exercise and psychosocial health estimate between subject effect sizes between low intensity no treatment and high intensity treatment group based Noom Coach Bariatric Health and validate local and global adherence algorithms for Noom Coach participants If Noom Coach for Bariatric Health does not produce benefits for participants in this phase of the study Phase II will not be initiated Phase II would compare usual pre operative care and pre surgical use of Noom Coach for Bariatric Health on post surgery adherence and psychosocial variables in a larger test n to explore whether usage of the app is a viable predictor of subsequent post operative weight trajectories months following surgery We hypothesize that app users will demonstrate greater adherence to diet and physical activity recommendations and better psychosocial adjustment following surgery In addition Phase II will use a sequential multiple assignment randomized trial SMART design to determine whether Noom Coach for Bariatric Health can augment weight loss post surgery based on weight loss from months Data will also be collected in Phase II to examine app usage as a viable predictor of subsequent post operative weight and psychosocial trajectories in the months post surgery and establish sensitivity and specificity of early optimal response to surgical intervention using anthropometric weight loss diet and exercise adherence and psychosocial adjustment If the efficacy of Noom Coach for Bariatric Health is demonstrated critical information will be available for developing a Phase III sequential multi phase adaptive trial aimed at informing algorithms for integration into Noom Coach more broadly and maximizing value within health care systems Mobile technologies smartphone applications offer a means to effect behavior change without significant obstacles that typically limit implementation of empirically supported therapies e g in person sessions however rigorous research on apps is limited and high quality adequately powered randomized controlled trials with large samples are required As more Americans consider bariatric surgery for the treatment of severe obesity it is imperative to improve factors influencing suboptimal surgical outcomes e g failure to adhere to diet and exercise recommendations and psychosocial impairment This application will evaluate the effect of the Noom Coach for Bariatric Health platform in improving standard interventions utilized in bariatric surgery programs
