Pre-diabetes | Device: Wearable technology Behavioral: Diabetes Prevention Programme educational material Behavioral: Motivational messaging | Not Applicable |
The study will examine whether a wearable technology, combined with biofeedback, motivational messaging and an e-diabetes prevention programme, is effective in reducing weight and increasing physical activity after 12 months.
The intervention will consist of a wearable technology and a smartphone application made available for a 12 month period. 22 online multimedia sessions targeting diet, physical activity and mental resilience delivered via the smartphone application. Motivational messaging based on the diabetes prevention module content and biofeedback will be sent to participants via the application.
The control group will receive the wearable technology and will have access to a smartphone application detailing their activity. Participants will be directed to the same educational material as is made available via the multimedia sessions, but will not receive motivational messages.

Experimental: Intervention
If participants are allocated to the intervention group, participants will receive the wearable technology and access to the smartphone application. Motivational messages based on diabetes prevention programme content, and biofeedback messages based on physical activity data provided via the wearable technology, will be received by participants via the application. The diabetes prevention programme educational material will be available via the application.

Active Comparator: Control
If participants are allocated to the control group, participants will receive the wearable technology and will be able to access their activity data via the smartphone application. Participants will also have have access to the diabetes prevention programme educational material via the application. Participants will not receive motivational messages related to the education content or activity data.

- Physical activity (average steps per day) [ Time Frame: 7 days ]Average steps taken per day from 7 days wear measured using the Buddi wearable technology, which will be worn 24 hours per day for 7 days
- Weight (kg) [ Time Frame: At 12 month follow-up appointment ]Measured in light clothing, without shoes, on the a Class 3 Tanita SC240 weighing digital scale to 0.01 kg for weight
- HbA1c (mmol/mol) [ Time Frame: At 12 month follow-up appointment ]
- Height (cm) [ Time Frame: At 12 month follow-up appointment ]
- BMI (kg/m^2) [ Time Frame: At 12 month follow-up appointment ]
- Waist circumference (cm) [ Time Frame: At 12 month follow-up appointment ]
- Hip circumference (cm) [ Time Frame: At 12 month follow-up appointment ]
- Total cholesterol (mmol/L) [ Time Frame: At 12 month follow-up appointment ]
- High density lipoprotein cholesterol (mmol/L) [ Time Frame: At 12 month follow-up appointment ]
- Low density lipoprotein cholesterol (mmol/L) [ Time Frame: At 12 month follow-up appointment ]
- Systolic blood pressure (mmHg) [ Time Frame: At 12 month follow-up appointment ]
- Diastolic blood pressure (mmHg) [ Time Frame: At 12 month follow-up appointment ]
- Sleep duration (average hours per night) [ Time Frame: 7 days ]The Buddi wearable technology will be worn for 24 hours per day. Therefore, during sleeping hours participant activity will be measured and duration of sleep can be calculated. Participants will wear the Buddi device for 7 days, and the average number of hours sleep per night will be calculated.
