Brief Summary

The emerging epidemic of type 2 diabetes mellitus (T2DM) in children is coupled with the increased prevalence of childhood obesity in the last two decades. Obesity during the adolescent years is associated with many adverse health consequences, including T2DM, hyperlipidemia, and psychosocial problems. The first step toward effective obesity management and T2DM prevention is monitoring of physical activity (PA) and dietary intake. With the rapid expansion of cellular networks, and advancements in smartphone technologies, it is now possible to monitor PA and dietary intake and at the same time to transmit data digitally to their primary care providers (PCP). The proposed pilot study will include the collaboration among UCSF, North East Medical Services (NEMS), mHealth teams, and overweight and/or obese adolescents. The study will adapt and implement smartphone-based technologies and integrate these technologies with the Electronic Health Record (EHR) to increase PA and dietary intake. Two specific aims of this proposed study include: (1) adapt fitbit Ultra applications for the smartphone-based technologies and EHR and (2) and assess the feasibility and estimate the effect for patient outcomes (self-efficacy, physical activity, dietary intake, BMI, and lipid profile), at 3 months post intervention between the intervention and control groups. The smartphone app for the intervention group will allow the teens to graphically compare daily PA and dietary intake with the goal, participate in a reward program where they can collect virtual points for achieving the goal, and play interactive games related to PA and diet. A total of 40 overweight and/or obese adolescents at NEMS will be recruited and randomized to the feasibility study (Aim 2).

Outcome Measures

Primary Outcomes (1)

  • Body Mass Index (BMI)

    Participants' BMI was determined by dividing body mass (weight) by height squared (kg/m2). Adolescents' weight and height were measured while the adolescents wore light-weight clothes and no shoes. For BMI, adequate sensitivity and specificity has been reported in children and adolescents, with sensitivity ranging from 29% to 88% and specificity ranging from 94% to 100%.

    baseline and 6 months

Other Outcomes (1)

  • Diastolic Blood Pressure

    baseline and 6 months

Study Arms (2)

fitbit ultra

EXPERIMENTAL

Adolescents in the intervention group will receive a Fitbit Ultra and will download an app to their smartphone. Participants will be asked to wear the Fitbit device and use the app every day for three months.

Behavioral: fitbit Ultra

Pedometer

ACTIVE COMPARATOR

After completion of the baseline assessments, adolescents in the control group will be given an Omron HJ-105 pedometer and a food diary and be asked to use them for three months.

Behavioral: Pedometer

Interventions

fitbit UltraBEHAVIORAL

Participants will be asked to wear the Fitbit device and use the app every day for three months. The app functions will include tracking of PA and dietary intake progress, setting individualized and realistic goals, monitoring progress related to reaching the goals, providing tips of everyday activities, and having interactive games related to PA and healthy diet.
