Zamzee Research Study and Pilot Insights
A project of
ZAMZEE RANDOMIZED CONTROLLED
TRIAL AND BIOMARKER STUDY
Nicole Guthrie MS, Fred Dillion BA, Jana Haritatos PhD, and Steve Cole PhD
OBJECTIVE
Assess the impact of Zamzee, an accelerometer-linked online motivational
system, on MVPA in a diverse sample of US middle school-aged children.
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.

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.

RESULTS
Within the biomarker sub-study,
the Zamzee group showed more
favorable pre to post-study changes
in LDL cholesterol, total cholesterol
and, in protocol-adherent
participants, HbA1c.
Non-significant effects were observed
for CRP and BMI.
