iStart Smart for Teens for Healthy Weight Management
A study testing fitbit Ultra and Pedometer in people with Overweight and Obese, run by University of California, San Francisco at 1 site in United States.
Trial 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. Read more about this study

About this study
Official title: Phase 1 Study of Fitbit and Apps on Healthy Weight Management in Obese Teens in Primary Care Clinics
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).
Read the detailed description
Using evidence to inform the design of clinical practice is a foundational principle of modern health care practice. In the present pilot study, using evidence from research on technology in clinical practice facilitated development of a hybrid intervention that combined lifestyle modification with routine clinical care. Chief among the benefits of this hybrid smartphone technology-based intervention (STB) was the potential to improve health outcomes and reduce obesity in overweight and obese adolescents. The purposes of this study were to (1) measure effects of an innovative smartphone-technology-based (STB) intervention for overweight and obese adolescents and to (2) examine the intervention's feasibility for use in primary care clinics.The STB intervention had 3 components: use of Fitbit Flex, participation in the online educational program, and receipt of bi-weekly text message during the maintenance phase. A randomized control study design was utilized. Data regard to anthropometrics (BMI and waist-hip ratio), blood pressure, levels of physical and sedentary activity, diet, and self-efficacy regarding physical activity and diet were collected at baseline, 3 month and 6 months after the baseline assessment.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
fitbit UltraBehavioural
Also called Fitbit Ultra and associated apps
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.
PedometerBehavioural
Also called Omron HJ-105 pedometer
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.
| Study group | Role | What they receive |
|---|---|---|
| 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. Receives: 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. Receives: Behavioral: Pedometer |
What is being measured
The primary outcome is the main question the study is designed to answer.
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%.
Measured: baseline and 6 months

Questions about this trial
What is this clinical trial studying?
A study testing fitbit Ultra and Pedometer in people with Overweight and Obese, run by University of California, San Francisco at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Aug 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 Aug 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Body Mass Index (BMI) (time frame: baseline and 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01693250, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Aug 2019.
