CODEC Study

Are you, or someone you know, living with diabetes?

Have you got type 1 diabetes or established type 2 diabetes? Were you diagnosed more than 6 months ago? If so you may be suitable to take part in our research study. 

Chronotype of Patients with Diabetes and Effect on Glycaemic Control: The CODEC Study

Research has shown that people who have later bedtimes (colloquially called ‘night owls’) are more likely to develop diabetes and other health problems, such as heart disease. This still holds true, even when the night owls get the same number of hours sleep as early risers. The underlying causes have not been clearly defined, but appear to be related to ‘circadian misalignment’. This is where societal pressures, such as work shifts, force us to wake earlier or stay awake longer than we naturally would.

The concept is called ‘social jetlag’ and has been developed to describe the damaging effects of chronic sleep deprivation related to this mismatching of sleep timing and chronotype. This is important because social jetlag has been associated with obesity, which increases the risk of developing type 1 and type 2 diabetes.

The CODEC study aims to identify the chronotypes in patients with type 1 and type 2 diabetes to find out what impact, if any, the chronotype (e.g. ‘night owl’ or ‘lark’) has on the patient’s ability to control their blood sugar levels, among other biological measures.

What’s involved?

The study consists of just one visit to the Kettering General Hospital and is looking at whether you are a morning or an evening type of person and how that affects diabetes.

You will also be informed of your results so see it as a free health check on us!
