Patients receive an iPhone with W8Loss2Go app, a body scale and a digital food scale to weigh themselves and food daily. Patients interact with coaches via text messages for 4 days weekly and receive weekly 15 minute phone calls for appointment reminders, emotional support, progress discussion, and follow up on items discussed in a prior visit or phone call. Patients also have telemedicine interviews with the coach lasting 60 minutes at 2 and 4 months to elicit both positive and negative impacts on weight management and to identify barriers such as emotional eating, displacement behaviors, poor coping skills to life stressors, and social challenges. Patients who opt to extend the intervention until month 12 attend an additional telemedicine meeting with the coach. Patients also complete questionnaires over approximately 1.5 hours.

This early phase I trial studies how well a behavioral weight loss intervention consisting of a smartphone application and coaching works for the promotion of weight loss in adolescents and young adults after a stem cell transplant. This study may help researchers learn more about how adolescents and young adults can lose weight and develop healthy eating habits.

PRIMARY OBJECTIVE:

I. To evaluate the effectiveness of an addiction-based weight loss intervention, embodied as a smartphone application (app) with telephone coaching, on weight outcomes of overweight and obese post hematopoietic stem cell transplantation (HSCT) adolescents and young adults.

SECONDARY OBJECTIVES:

I. To evaluate the changes in metabolic parameters and physical activity levels, in addition to modifications in addictive eating behaviors, motivation, and self-regulatory behaviors.

II. To evaluate the feasibility, adherence, and satisfaction of this intervention.

OUTLINE:

Patients receive an iPhone with W8Loss2Go app, a body scale and a digital food scale to weigh themselves and food daily. Patients interact with coaches via text messages for 4 days weekly and receive weekly 15 minute phone calls for appointment reminders, emotional support, progress discussion, and follow up on items discussed in a prior visit or phone call. Patients also have telemedicine interviews with the coach lasting 60 minutes at 2 and 4 months to elicit both positive and negative impacts on weight management and to identify barriers such as emotional eating, displacement behaviors, poor coping skills to life stressors, and social challenges. Patients who opt to extend the intervention until month 12 attend an additional telemedicine meeting with the coach. Patients also complete questionnaires over approximately 1.5 hours.

A Study to See if an iPhone Weight Management App Can Help Promote Weight Loss in Adolescents and Young Adults After a Stem Cell Transplant

Behavioral Weight Loss Intervention Utilizing Mobile Health Technology in Hematopoietic Stem Cell Transplant Patients (BWL001)

The main outcomes measures will be height (meters), weight (kg), and BMI (kg/m\^2). Height will be measured to assess consistency in height measurements. Weight will be measured to assess trends in weight over the time span of the intervention. BMI will be measured as a product of weight and height to obtain an appropriate metric that accounts for these measures, and is the standard measure to assess weight progression in weight intervention studies.

Compliance with app intervention will be measured by daily interaction with the application and the coach. A point system has been designed in the application to measure compliance with the app intervention, measured by +/- weight measured daily, logging of problem foods, logging of snacking panel, and logging of meals. The coach interacts with the participants through text daily, and through phone calls weekly.

HbA1c: Glycated hemoglobin (A1C) test result reflects your average blood sugar level for the past two to three months. Specifically, the A1C test measures what percentage of your hemoglobin is coated with sugar. The healthy range is between 4% and 5.6%

Total cholesterol: This measures the overall amount of cholesterol in your blood. The healthy range is \< 170 mg/dL

LDL: low density lipoprotein (LDL) is the bad cholesterol in your blood. The healthy range is \<100 mg/dL

HDL: high density lipoprotein (HDL) is the good cholesterol in your blood. The healthy range is \> 45 mg/dL

TG: triglycerides (TG) are a type of lipid in your blood. The healthy range is \< 150 mg/dL

AST/ALT: aspartate/alanine aminotransferase (AST/ALT) are liver enzymes to measure liver health. The healthy range or AST is 10-34 IU/L and the healthy range for ALT is 8-37 IU/L.

Glucose: This measures the amount of sugar in your blood. We measure this after fasting for 8 hours. The healthy range is 70-99 mg/dL

visual analog scale (1: never to 5:always). Higher scores may suggest more addictive like eating

4 categorical options (never/rarely, sometimes, moderately, all of the time). A higher score suggests utility for screening for depression

Likert Scale (0: never to 4:very often). Higher scores suggests higher stress

Measured by "Satisfaction Survey". This Likert Scale will be completed by the participant and their parent at the end of the study. This scale uses a Likert Scale where 1 = completely disagree to 7 = completely agree. Higher scores suggest greater satisfaction with the intervention.

10 questions with varying options to inquire about common demographic questions (gender, age, primary language, etc). Questions are descriptive in nature and no score is assigned.

Likert scale (1: never to 5: always). A higher score suggests higher degrees of food cravings

4 categorical options (never/rarely, sometimes, often, always). A higher score suggests utility for screening for binge eating disorder

participants identify number of times (0 to more than 7) that they conducted a particular physical activity in the past 7 days. This includes skipping, rowing, etc.

Likert scale (1: strongly disagree to 5: strongly agree). Higher scores indicates more motivation for change in weight

six questions about the participants health care utilization in the past month. Questions are descriptive in nature and no score is assigned.
