Abstract

A general description of the multinational study under the auspices of the World Health Organization is presented. The purpose was to compare the prevalence of vascular disease in representative samples of diabetic subjects of different ethnic and cultural habitus. Standardized methods of investigation were devised. Fourteen centers participated, and the data collected so far indicate that the characteristics of the populations studied varied as to age composition, adiposity, cigarette smoking, treatment, age at diagnosis, and duration of diabetes. Thus, taking these factors into consideration and while awaiting completion of the data, conclusions must be drawn with reserve.
