Obesity and Type 2 Diabetes Interventions to Increase Physical Activity: The BEAM Study

Behavioral Economics for Activity Motivation (BEAM) in Adolescents and Young Adults with Prediabetes and Type 2 Diabetes

Protocol Description

The goal of the BEAM study is to develop an effective mHealth intervention to increase moderate-to-vigorous physical activity in obese adolescents and young adults with prediabetes or type 2 diabetes (T2D). Sometimes called mobile health, mHealth harnesses portable wireless technologies to aid in achieving specific health objectives. Despite the many cardiovascular and diabetes-related benefits of physical activity, adolescents and young adults with T2D are significantly less active than non-diabetic peers. Using insights from behavioral economics and a highly efficient framework, this trial evaluates several strategies, including text messages, financial incentives, and variations in step-count goal assignment. Researchers will determine the impact of these strategies on physical activity, biochemical measures, and body size.

Eligibility Criteria

Subject to certain exclusion criteria, this study is enrolling teens and young adults with diagnosed T2D or prediabetes and who are overweight.
Males and Females: Ages 13 through 22


Participants will have 2 study visits, 14 weeks apart, to complete fasting bloodwork, questionnaires, a physical exam, and review program parameters. Between the visits, participants will wear an activity tracker, receive text messages, and receive financial incentives for meeting step count goals.
Visits: 2
Duration: 14 weeks

Status: Open to Enrollment
