A Scalable Weight Control Intervention for Adolescents (TEEN JOIN)

TEEN JOIN: A Scalable Weight Control Intervention for Adolescents

Community-based programs are needed to improve dissemination of efficacious treatment for adolescent obesity. The current study aims to modify a community-based program, delivered through the YMCA, to increase its effectiveness with adolescents. Adolescents will be randomized to either a 16-week standard program (JOIN) or a targeted intervention tailored for adolescents (TEEN JOIN). Primary outcomes include changes in BMI, objectively measured physical activity, and self-efficacy, assessed at 4 months and 10 months following randomization.

Detailed Description

In 2010, the U.S. Preventive Services Task Force (USPSTF) provided a Grade recommendation B (i.e. the service is recommended with moderate/high certainty of benefit) for clinicians to screen children ages 6-17 years for obesity and refer identified youth to comprehensive behavioral programs. The challenge in meeting this objective is the lack of community-based obesity treatments to which to refer, particularly for adolescents. The JOIN program, developed as a collaboration between United HealthGroup and Y-USA is a pediatric weight control intervention targeted toward a broad age range of youth from 6-17 years that is: 1) based on well established and evidence based principles; 2) delivered by YMCA facilitators within a community setting: and 3) potentially scalable nationally. Findings from a 6-month pilot study examining the effectiveness of JOIN demonstrated impressive changes in weight status for school age children, but more modest results for adolescents. The primary aim of this study is to modify the JOIN program to increase its effectiveness with adolescents while retaining its potential for scalability.

A total of 120 adolescents (ages 13-17) with BMI > 85th% and < 50 will be randomly assigned to a 16-week targeted program (TEEN JOIN), or the traditional JOIN intervention, followed by biweekly and monthly maintenance sessions. Evaluation of adolescent height, weight, objective physical activity and psychosocial outcomes will be obtained at baseline, 4 months, and 10 months. Additional outcomes will include treatment feasibility, including attendance, completion of diet and physical activity monitoring logs, and exit interviews with adolescents and parents regarding the intervention. The investigators will also obtain preliminary indicators of cost effectiveness. It is hypothesized that adolescents who are randomized to TEEN JOIN will demonstrate greater decrease in BMI at 4 and 10 months than those randomized to JOIN. It is further hypothesized that adolescents randomized to TEEN JOIN will demonstrate greater increases in participation in moderate-vigorous physical activity and greater improvements in self-concept, self-efficacy related to physical activity, and group cohesion than adolescents who receive the standard JOIN condition.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: JOIN FOR ME
The JOIN for ME curriculum includes 16 weekly in person sessions followed by 4 biweekly and 4 monthly maintenance sessions for a 10-month program. Weekly meetings are scheduled for 60 minutes and are facilitated by a YMCA coach. Interventions include behavioral weight control and parent-based incentives. Parents attend group at weeks 1, 2 and 16 with their teen.
Behavioral: Behavioral weight control
Prescription of diet & physical activity and behavioral strategies for weight control
Behavioral: Parent-based incentives
Adolescents earn reinforcements from their parents (outside of group)
Experimental: TEEN JOIN
Similar to the JOIN FOR ME condition, adolescents in the TEEN JOIN condition attend 16 weekly in person sessions followed by 4 biweekly and 4 monthly maintenance sessions for a 10-month program. Interventions include behavioral weight control, group-based physical activity, and group-based incentives. Parents attend separate meetings at weeks 1, 2, and 16.
Behavioral: Behavioral weight control
Prescription of diet & physical activity and behavioral strategies for weight control
Behavioral: Group-based physical activity
Teens exercise for 60 minutes with their group
Behavioral: Group-based incentives
Adolescents earn reinforcements within group
