Medical information on 90,596 employees of a large company was surveyed during 1956 and 1957 in an appraisal of facts regarding diabetes. The company physicians reported on 408 employees having the disease and an equal number of nondiabetic employees matching the diabetic group as to age, sex, occupation, and location. The incidence of diabetes was 4.5 per 1,000 employees, 4.8 for men (370) and 2.7 for women (38). No significant difference was found in the distribution of ABO blood groups between diabetics and nondiabetics. Although obesity was more common to the diabetics, 92.1% of them had been able to lose weight since the discovery of their diabetes. Hypertension occurred more frequently in the employees with diabetes, especially those overweight, but obesity could not be singled out as the main cause of the hypertension.
