About this study
This study seeks to address two questions. Firstly, how might a suite of interventions and data feedback (activity, diet, mood*, continuous blood glucose) through coaching be effective in influencing behaviour change for individuals at-risk of developing type 2 diabetes? Secondly, what elements of coaching might be extracted for automated implementation in a scalable coach-light model?
Read the detailed description
Face-to-face health coaching is a common lifestyle intervention for healthy individuals who are at risk of chronic diseases such as diabetes. However, it is highly resource-intensive and has limitations in scaling up to reach wider populations. Advances in technology present opportunities to scale health coaching to the wider population through automation, enabling the delivery of personalised messages for individuals via mobile applications.
In addition, continuous glucose monitoring (CGM) devices could also potentially augment the effectiveness of health coaching by providing coaches with a tool for coachees' self-discovery of their individual physiological responses to lifestyles and modifications such as diet and exercise.
As such, the present study seeks to leverage smart wearable devices (e.g., Bluetooth smartwatches) and CGM devices accompanying a customized mobile application to deliver lifestyle coaching interventions. This suite of lifestyle interventions, including feedback about their own blood glucose levels, aims to influence participant's lifestyles and behaviours through guided self-discovery and face-to-face coaching. This intervention will be compared with a control group to examine its effects on lifestyle change, anthropometric measures and biometric measures. In addition, the findings from this study will contribute to the development of a novel coach-light intervention that can be implemented at a wider population level via Singapore's Health Promotion Board's (HPB) existing programmes and channels.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
CGM lifestyle tracking and coachingDevice
Participants in the experimental group will go through a total of 5 lifestyle tracking sessions (including baseline), of which 1 will include CGM tracking. For this CGM lifestyle tracking session, experimental group participants will receive real-time feedback through the study applications, which will display the CGM trace.
The data collected during the lifestyle tracking sessions will be discussed with the participants during 3 face-to-face coaching and 2 tele-coaching sessions, where the participants will develop and implement lifestyle change action plans.
| Study group | Role | What they receive |
|---|---|---|
| Control group | No intervention | The health screening before the study and at the end of study will collect anthropometric data (height, weight, waist and hip circumference), blood pressure data, and blood samples (for testing of HbA1c, fasting blood glucose, fasting insulin and lipid profile). Individuals are provided with an educational brochure upon receiving their screening results. Participants will then go through a baseline lifestyle tracking session using a study-issued smartphone and smartwatch, pre-installed with certain study applications. For participants in the control arm, there is no health coaching or study activities until the end of the study, where individuals will attend a 20- to 30-minute session with a coach to have their baseline lifestyle tracking results explained to them and receive personalised suggestions on lifestyle modifications. |
| Experimental group | Experimental | The activities during health screening before the study and at the end of study is similar to the control. Individuals are provided with an educational brochure upon receiving their screening results. Participants will then go through a baseline lifestyle tracking session using a study-issued smartphone and smartwatch, pre-installed with certain study applications, which will be used for the lifestyle tracking sessions. The experimental arm will go through 4 additional lifestyle tracking sessions (i.e., total of 5 including baseline), of which 1 will include Continuous Glucose Monitoring (CGM) tracking. For this CGM tracking session, participants will receive real-time feedback through the study applications, which will display the CGM trace. The data collected during the lifestyle tracking sessions will be discussed with the participants during 3 face-to-face coaching and 2 tele-coaching sessions, where the participants will develop and implement lifestyle change action plans.

- This is an experimental-control study design where up to 260 individuals at risk of developing diabetes (blood glucose levels of 6.1 to 6.9 mmol/L) will be randomly allocated to the experimental and control groups (1:1 randomization). Participants in the control group will not receive any health coaching and are not required to carry out any study activities after they have completed the baseline lifestyle tracking session.

Clinical summary

This study seeks to address two questions. Firstly, how might a suite of interventions and data feedback (activity, diet, mood*, continuous blood glucose) through coaching be effective in influencing behaviour change for individuals at-risk of developing type 2 diabetes? Secondly, what elements of coaching might be extracted for automated implementation in a scalable coach-light model?

Questions about this trial
What is this clinical trial studying?
A study testing CGM lifestyle tracking and coaching in people with Pre-diabetes, run by National University of Singapore at 1 site in Singapore.
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 6 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 1 Dec 2021. 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 Singapore. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Karen Cheong (+65-64353673, Karen_Cheong@hpb.gov.sg), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Behaviour, self-efficacy and attitudes (time frame: Baseline and at month 3). 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 NCT04905680, which also lists 4 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 1 Dec 2021.
