MPOWERed Messages: Tailored Mobile Messages to Enhance Weight Loss for Teens

Novel Individually Tailored Mobile Messages to Enhance Weight Loss for Teens

Obesity affects millions of American children and increases their risk of adult obesity, a myriad of serious illnesses, increased healthcare costs, and premature death. It is vital to find ways to reverse this epidemic. Multidisciplinary behavioral weight management programs offer the promise of effectively treating childhood obesity. However, participants in such programs often find it challenging to follow recommended treatment plans and frequently drop out from programs without completing them. The proposed project aims to address these problems through frequent contact with patients between office visits. This interim contact will be achieved by automatically sending tailored messages to the mobile phones of adolescents enrolled in a multidisciplinary weight management program (the MPOWER program), as an adjunct to clinic visits.

The investigators hypothesize that program participants who receive the tailored text messages will experience lower attrition rates, increased treatment adherence, and greater weight loss compared to those program participants who do not receive the messages.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Text Messaging	Behavioral: Tailored Mobile Messages to Enhance Weight Loss for Teens; For this trial adolescents will be allowed to use their own phone (with reimbursement for any study-related costs), or will be provided with a mobile phone, if requested. Participants will receive messages delivered daily over the course of 20 weeks. The content of the messages will be tailored on participants' responses to the MPOWER enrollment survey and the initial tailoring questionnaire. On school days, all messages will be sent after 3 pm (which is after school hours for most Michigan middle and high schools). Therefore, patients will not need to carry cell phones to school. The tailored messages will utilize various degrees of personalization, adaptation and feedback - including momentary assessments with feedback requiring a text reply from the adolescents.; Other Names: MPOWERed Messages
No Intervention: Control; Participation in the MPOWER program without receiving tailored text messages

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Session attendance	Over the course of 6 months
Adherence to MPOWER program homework assignments	Over the course of 6 months
Satisfaction with the MPOWER program	At the completion of 3 months and 6 months in the program
Drop out	Prior to completion of the 6 month program

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in body mass index		After 3 months and 6 months in the MPOWER program
Objective measurement of daily participation in moderate to vigorous activity		After 3 months and 6 months in the MPOWER program
Self-efficacy for achieving MPOWER recommendations for the 6 target behaviors	Using a self-efficacy scale developed by Resnicow we will measure self-efficacy for consuming breakfast daily, achieving recommended amounts of fruits and vegetables, obtaining 60 to 90 minutes of moderate to vigorous physical activity on most days, limiting fast food consumption to no more than once per week, consuming no more than three 8 oz servings of sugar-sweetened beverages per week, and engaging in no more than 2 hours of screen time per day.	After 3 months and 6 months in the MPOWER program6 month
Intrinsic motivation to increase intake of fruits and vegetables and to increase physical activity	Intrinsic motivation will be measured using the Treatment Self-Regulation Questionnaire for Nutrition and the Treatment Self-Regulation Questionnaire for Physical Activity	After 3 months and 6 months in the MPOWER program
Change in self-report of the six behaviors targeted in the intervention	The behaviors addressed are: Breakfast (self-report, in response to the question, During the last 7days, how many days did you eat breakfast?) Fruits and vegetables (24 hour food recall) Fast food (self-report in response to the question, During the last 7 days, how often did you eat food purchased at a fast food restaurant?) Sugar-sweetened beverages (24 hour food recall) Screen time (self-report in response to questions regarding number of hours of screen time per day on school days and non-school days) Physical activity (self-report using the Fitnessgram Activity log)	After 3 months and 6 months in the MPOWER program
