The Iranian Journal of Diabetes and Obesity (IJDO) is the official scientific quarterly journal published by Yazd Diabetes Research Center of Shahid Sadoughi University of Medical Sciences and Health Services. The primary purpose of IJDO is to act as a source of information, usable by those caring for patients with diabetes mellitus and obesity. While our primary aim is to assist the practitioner in his/her care of such patients, and to afford access to information that may allow the prevention of diabetes, it is the Editors’ wish to function as a forum for that information which, while still experimental, may shed light upon current thinking of those active in the fields appropriate to the aims of IJDO. In addition to general articles on clinical aspects of diabetes mellitus and obesity, IJDO presents articles on basic research in all areas of diabetes. Topics covered relevant to the diabetic patient will include diagnosis, pathogenesis and clinical management of diabetes and obesity. IJDO will also publish papers on the general pathogenesis and prevention of diabetes.
