Study type
Interventional
Description of intervention(s) / exposure
Patients with type 2 diabetes wore a continuous glucose monitor and an Apple Watch for 12 days. Uploaded data (activity (steps), heart rate, blood glucose level) were integrated into an App (specifically designed for the study) which also enabled the recording of activity and food consumed. This was completed multiple time each day by the participants every time they exercised or ate. A physician (endocrinologist) provided text-based daily feedback to each individual, based upon their data from each day of the study. App analytics were accessed to assess compliance

Summary
Brief summary
In view of the expected epidemic of type 2 diabetes, there is an urgent need for large-scale interventions that can prevent the progression from pre-diabetes to diabetes through encouraging change in health-related behaviours. We have set out to test the acceptability of receiving daily physician’s feedback informed by wearable continuous monitoring of subjects’ activity, food choices and glucose profiles with the aim of encouraging healthier behaviours in subjects with diabetes.

Fifteen subjects with type 2 diabetes wore a continuous glucose monitor and an Apple Watch for 12 days. Uploaded data were integrated into an App which also enabled the recording of activity and food consumed. A physician provided text-based daily feedback to each individual, based upon their data from each day of the study. At the beginning and the end of the study,data was collected on health related-behaviour, such as eating and exercise, and diabetes control assess the acceptability of the intervention.

Results – plain English summary
WE have demonstrated that providing daily physician-driven feedback to diabetic patient based on continuous glucose monitoring and exercise and food intake data improves health-related behaviours and glycaemic control. There were trends to improvement in body weight and cardiovascular risk parameters also.
