A Pilot Study to Assess the Compliance and Impact on Weight of Kurbo, a Pediatric Centered Weight Loss App (Preprint)
BACKGROUND The national prevalence of adolescent obesity has increased from 5% to 21% over the last five decades. Lifestyle modification continues to be the cornerstone of treatment for obesity and its comorbidities, and a number of digital tools have been developed as adjuncts to foster weight and BMI decrease. Apps targeting the pediatric population are few and none to date have been validated with scientific studies assessing their feasibility and outcomes. OBJECTIVE The purpose of this pilot study is to establish compliance and feasibility of Kurbo, a pediatric-centered weight loss app, as an adjunct to our pediatric weight management clinic. METHODS Kurbo utilizes games and activities to educate children about healthy eating and exercise. Kurbo also includes the option of personalized weekly feedback with a learning coach that covers basic nutrition education, behavior modification tools, and action plans to reach weekly food and exercise goals. Subjects were primarily English speaking, aged 10 through 17 years old, with regular access to a smart device, and who were seen at Baystate Children’s Hospital outpatient weight management clinic. Participants were randomized to receive the Kurbo app or Kurbo plus a learning coach in addition to standard of care. Subjects were seen monthly by the dietitian or physician, where BMI was determined, and questionnaires assessing use of the app were answered. RESULTS Twenty-seven subjects were enrolled; 13 in the Kurbo group and 14 in the Kurbo plus learning coach group. Compliance overall was poor, with only 15% of subjects completing the required follow-up visits and approximately 7% and 4% of subjects self-reporting > 75% compliance with food or exercise tracking, respectively. A small increase in compliance was noted in app collected versus self-reported data. CONCLUSIONS Future studies might look into enrolling more motivated patients who might utilize the app more and have better outcomes.
