The Integration of Physical Activity Into the Clinical Decision Process of People With Type 1 Diabetes (ENHANCED1)

The Integration of Physical Activity Into the Clinical Decision Process of People With Type 1 Diabetes

Proof-of-concept Study for the Integration of Physical Activity Into the Clinical Decision Process of Physically Active People With Type 1 Diabetes

Every person with type 1 diabetes needs personalized advice to integrate physical activity into daily diabetes management. The purpose of this study is to collect data on food intake, physical activity, glucose levels and insulin delivery from people with type 1 diabetes who are physically active. At least 25 people with type 1 diabetes will be asked to perform 25 sports activities of at least half an hour, wear an activity tracker (day and night) and chest strap (during sports activities), and log data on food intake, periods and type of physical activity, and feelings (e.g., sick, stress) in a diary app. Diabetes data such as insulin administration and sensor data will be collected through diabetes management platforms. The primary endpoint involves a database containing data on glucose, insulin administration, physical activity, and food intake of people with type 1 diabetes for statistical analyses and visualizations regarding the relationship between physical activity and blood glucose response.

During the study, the participants will be asked to wear a commercially-available activity tracker during day and night, and a chest strap during sport activities to collect data on physical activity (type, intensity and duration of activity).

During the study, the participants will be asked to log the ingestion of carbohydrates, periods and type of physical activity, feelings (e.g. sick, stress, ...) in a diary app.

Database which contains insulin data (insulin dose over time) retrieved from diabetes management platforms.

Database which contains glucose data (glycemic values over time) retrieved from diabetes management platforms.

Database which contains physical activity data (type of activity) retrieved from the activity tracker and chest strap.

Database which contains physical activity data (intensity of activity) retrieved from the activity tracker and chest strap.

Database which contains physical activity data (duration of activity) retrieved from the activity tracker and chest strap.
