**2. Search strategy for identification and selection of studies**

We identified relevant studies published in English by searching MEDLINE from January 1990 to December 2010. We included randomised and quasi-randomised controlled studies, clinical series, reviews and systematic reviews on type 1 diabetic patients with inadequate coping attitudes, disordered eating behaviors and eating disorders, in which children, adolescents and young adults with type 1 diabetes were properly defined. As study strategy, relevant questions about type 1 diabetes and eating disorders were previously determined: coping with diabetes, epidemiology, clinical forms of eating disorders and specific behavioral anomalies in type 1 diabetic patients, metabolic consequences and vascular complications, management and prevention.
