Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The first main outcome is glycaemic control, measured with fasting blood glucose levels, HbA1c levels, and 2h glucose levels after an oral glucose tolerance test, comparing those with and without social jetlag. | — |
Secondary
| Measure | Time frame |
|---|---|
| Additionally, to assess which factors mediate this association, we will assess physical activity, (para)sympathetic nervous systemactivity from ECGs and electrochemical skin conductance tests, the Dim Light Melatonin Onset (DLMO) in saliva samples, HPA-axisactivation from cortisol awakening reaction in saliva samples and visceral fat distribution.Physical activity and sleep times and phases will be measured using an activity tracker and a sleep measuring headband. Dietaryintake will be assessed from the central Hoorn Study visit (or the RISC of HOM study visit). | — |
