Zamzee combines individualized feedback, progress monitoring and goal setting, tangible incentives, and intrinsic motivation features to promote long-term increase in physical activity as measured by a 3-axis accelerometer system with automated upload to a central database. BACKGROUND Most US adolescents do not achieve CDC-recommended levels of moderate-to- vigorous physical activity (MVPA), placing the next generation of Americans at increased risk for a diverse array of chronic diseases. There is a great need for new scalable interventions that can persistently increase MVPA in adolescents. CONCLUSIONS The Zamzee activity meter/motivational website system can consistently increase MVPA over 6 months in middle school-aged children, with favorable effects on blood lipid and metabolic parameters. PRIMARY OUTCOMES STUDY DESIGN & DEMOGRAPHICS THANK YOU TO OUR PARTNERS The participants, families, physicians and administrators of the pediatric weight management pilot sites. INSIGHT 1 Average Weekly Minutes of Physical Activity SELF-REPORTED MINUTES 571 ZAMZEE MEASURED MINUTES 237 INSIGHT 2 Average Attendance (Completion Rate) at Final Class Zamzee Pilot Cohort has Increased Program Completion Rates Compared to Historical Average HISTORICAL AVERAGE 57% ZAMZEE PILOT* 87% *Sub-set of total population n= 31 OBJECTIVE Assess the impact of Zamzee on children and family members enrolled in pediatric weight management clinics. BACKGROUND Many healthcare providers now offer weight management clinics to children and families struggling with childhood obesity. As part of promoting healthy behavior change, there is a great need in these clinics for scalable, low-cost interventions that increase the physical activity of clinic participants. ZAMZEE IN PEDIATRIC WEIGHT MANAGEMENT CLINICS Findings from Pilot Study SUMMARY The use of Zamzee in pediatric weight management clinics in the pilot project provided physicians with an objective measurement of physical activity which differed significantly from self-reported data. In addition, use of Zamzee resulted in an increased percentage (52% at one pilot site) of participants completing the assigned program. Moreover, we saw higher engagement with the Zamzee program when it was used as a family (84% versus 17%). These are promising indicators that Zamzee could be a scalable, low-cost intervention that increases the physical activity of children enrolled in pediatric weight management clinics.
