Eating Disorders in Type 1 Insulin-dependent Diabetes Patients

To determine eating disorder prevalence in differentiated adult men and women with type 1 insulin-dependent diabetes.

Patients answer to the SCOFF-F questions :

• do you make yourself sick because you feel uncomfortably full?
• do you worry that you have lost control over how much you eat?
• have you recently lost more than one stone in a 3 month period?
• do you believe yourself to be fat when others say you are too thin?
• would you say that food dominates your life?

Every "yes" attributes one point and gives a final score between 0 and 5; a score ≥2 indicates an eating disorder.

To determine eating disorder prevalence in undifferentiated cohort (men and woman) with type 1 insulin-dependent diabetes.

Patients answer to the SCOFF-F questions :

• do you make yourself sick because you feel uncomfortably full?
• do you worry that you have lost control over how much you eat?
• have you recently lost more than one stone in a 3 month period?
• do you believe yourself to be fat when others say you are too thin?
• would you say that food dominates your life?

Every "yes" attributes one point and gives a final score between 0 and 5; a score ≥2 indicates an eating disorder.

To Determine the auto declared insulin under dosage prevalence in undifferentiated cohort (men and woman) with type 1 insulin-dependent diabetes.

Patients answer to the 5th m-SCOFF question :

• do you ever take less insulin than you should?

A "yes" answer means that patient underdoses insulin treatment.

To identify if there is a link between an eating disorder and overall glycemic control, we will look after the last biological value of HbA1c rates

To identify if there is a link between an eating disorder and basal/bolus insulin ratio, we will extract and compare to eating disorder presence, this daily data from insulin pump over the 14 days preceding inclusion

To identify if there is a link between an eating disorder and boluses performed per day, we will extract and compare to eating disorder presence, this daily data from insulin pump over the 14 days preceding inclusion

To identify if there is a link between an eating disorder and body composition, we will perform a bio-electric impedance analysis and compare the result to eating disorder presence.

To identify if there is a link between an eating disorder and continuous glycemic control, we will extract and compare to eating disorder presence, this data from the continuous glucose monitoring system (CGMS) over the 14 days preceding inclusion Glycemic control will be determined by the percentage of daily time into the glycemic target (between 70 and 180 mg/dL).

To identify if there is a link between an eating disorder and glycemic variability, we will extract and compare to eating disorder presence, this data from the continuous glucose monitoring system (CGMS) over the 14 days preceding inclusion Glycemic variability will be determined by the Mean Amplitude of Glycemic Excursions (MAGE) algorithm.

To identify if there is a link between an eating disorder and the adherence to the continuous glucose monitoring system (CGMS), we will extract and compare to eating disorder presence, this data from the continuous glucose monitoring system (CGMS) over the 14 days preceding inclusion Adherence will be determined by the number of minutes worn per day.

To identify if there is a link between an eating disorder and blood glucose monitoring, we will extract and compare to eating disorder presence, this data from the continuous glucose monitoring system (CGMS) over the 14 days preceding inclusion The monitoring will be determined by the number of scans done per day.
