Brief Summary

In the general population, the excessive and constant desire to control one's diet and body has become increasingly problematic. Indeed, the demand for control over one's diet and body is now an unspoken social prescription that can lead in some cases to eating disorders. In patients with type 1 diabetes (T1D), these concerns are even more central, as they are accentuated by the very nature of the treatment of the disease (dietary modification, insulin compensation according to food intake, etc.). Studies on adolescents with T1D show that the prevalence of eating disorders would be present in at least 1 in 5 patients. Among these disorders, orthorexia is of particular interest. Indeed, orthorexia was defined in 1997 by Steven Bratman as a rigid eating behavior based on the avoidance of foods considered qualitatively unhealthy. More precisely, orthorexia is characterized by a constant preoccupation with one's diet and persistent nutritional (or health) beliefs that take precedence over food pleasure. It has been estimated that the prevalence of orthorexia in patients living with T1D may be as high as 80%. We are currently conducting a study on the mechanisms of orthorexia in the general population of Quebec (the results of phase 1 of this study are being analyzed). We now wish to conduct the same study in a population with T1D, which has a higher prevalence of people with orthorexia nervosa. The main objective of this study is to investigate the characteristics of orthorexia nervosa (obsessions and fixations on healthy eating) in the Quebec population with T1D from the BETTER Registry.

Outcome Measures

Primary Outcomes (1)

• Forced food categorization task according to the categories "healthy / unhealthy"

  Instruction to the participant: "Classify the food that appears on your screen as quickly as possible, either as "healthy" (key E) or "unhealthy" (key I). Each response and the associated reaction time will be recorded. Stimuli must be classified by the participant as quickly as possible, if the stimulus is not classified before 3 sec the participant moves to the next observation and the stimulus is recorded as NC (not classified).
