Blood pressure variations of 30 insulin-dependent diabetic patients free of complications, and aged between 14-35 years have been studies, comparing their results to those from a control group formed by healthy person of the same age and physical features. Median systolic pressure of diabetic population was 120 +/- 11.07, compared to 112.90 +/- 11.31 from control group. The median diastolic pressure of diabetic population was 76.76 +/- 10.12 and 67.40 +/- 7.94 of the control group. A significant difference on systolic (p less than 0.05) and diastolic (p less than 0.001) pressures were observed in insulin-dependent diabetic patient comparing their results to those from the control group.
