Bone mineral density in diabetes mellitus.
In the present study bone mineral content (BMC) was measured at 1/3 and 1/10 the length of the radius from the distal end in 100 adult diabetic subjects (55 females, 45 males, 54 insulin-dependent [IDD], 46 non-insulin-dependent [NIDD]), using single photon absorptiometry. Each individual BMC value in the diabetics was first compared to normal BMC values for age obtained in our laboratory from 500 non-diabetic subjects. BMC in the diabetics was within the normal range (M +/- 2 SD) with respect to sex and age. Data from IDD and NIDD males, under and over 50 years of age, and of IDD and NIDD females, pre- and postmenopausal, were compared with the respective control group data after matching each diabetic subject to a non-diabetic one of identical age and menstrual history and of comparable body mass index. In each group BMC in the diabetic subjects was found not to be statistically different from BMC in the control ones. Correlation analysis was carried out between BMC and endocrine or metabolic parameters obtained in 52 of the diabetic patients. BMC in diabetic subjects was not correlated with plasma levels of hormones (thyroid hormones, cortisol, 17-beta-estradiol, testosterone), Ca, P or alkaline phosphatase activity. It was inversely correlated with urinary Ca and P in NIDD women and with urinary Ca in NIDD men. No relationship was found between BMC and the metabolic control of diabetes (evaluated by basal glycemia, 2h-post-prandial glycemia and glycosylated hemoglobin).
