People with Type 2 Diabetes (PwT2D) benefit from more physical activity (PA), less sedentary behavior (SB) and optimal sleep. Previous research in PwT2D studied these behaviors separately. Now, the focus shifted to an integrated approach regarding the behaviors conducted in a 24h day: PA, SB and sleep or the so-called 24h movement behaviors (24hMBs). The composition of these 24hMBs and their associations with daily glucose profiles in PwT2D has not yet been investigated although a change in time in one of the behaviors has an effect on the time dedicated to the others, and PA, SB and sleep are behaviors that influence glucose profiles. PwT2D can benefit from optimizing their 24hMBs since this will have an influence on their glucose profiles, which is a first step in decreasing complications later in life. Within this project, we will first investigate associations and changes over time between 24hMBs and daily glucose profiles in PwT2D. Then, we will work closely together with PwT2D to develop an intervention to positively impact and optimize their 24hMBs, taking their preferences and needs into account. The effect of this intervention will be evaluated using an experimental design with 8 different conditions which will enable us to optimize the intervention. The results of this project will pave the way for implementation of the developed intervention into clinical practice. This intervention is expected to cause an improvement of longer-term consequences of the disease.
