Relationship between high fasting blood sugar and depression in a mental hygiene clinic population.

The relationship between diagnosis and abnormally high fasting blood sugar levels was reviewed for 4,994 patients in a mental hygiene clinic. Fifty-four patients exceeded the criterion level of fasting blood sugar abnormality, FBS greater than or equal to 145 mg%. There was no evidence of relationship between psychiatric diagnosis and the presence of an abnormally high fasting blood sugar level. This held true for the diagnosis of depression despite observations made elsewhere that a significant association exists between the depressions and diabetes.
