Detailed description: The goal of this study is to conduct a chart audit on all patients with type 1 diabetes who have been seen collaboratively by International Diabetes Center (IDC) and Park Nicollet Eating Disorder Institute (EDI) staff from 2005 - 2008 and their matched eating disordered controls.

Research Questions

1. What are the general characteristics of the ED DM T1 population?
2. How are ED DM T1 patients different from the matched eating disordered patients with respect to race, marital status, age of onset, eating behaviors, self-reported highest and lowest weight, exercise frequency and duration, number of hospital admissions, number of emergency room visits, medication needs, and other medical and psychological/psychiatric comorbidities?
3. How are ED DM T1 patients different from the matched eating disordered patients with respect to the affective and cognitive aspects of eating disorders such as self-reported depression symptoms, body image distortion, thoughts and feelings about eating, psychological concerns, readiness to change, self-esteem and anxiety?
4. For ED DM T1 patients, what is the time relationship of the diagnosis of diabetes and an eating disorder?
5. For ED DM T1 patients, what is the relationship of BMI and A1c?
