Growth of fetuses of diabetic mothers

Longitudinal ultrasonographic examinations, with measurements of fetal biparietal diameter and abdominal circumference, were performed in 85 diabetic pregnant women submitted to different treatment protocols. Curves of fetal growth parameters were obtained for each group of patients and for a control group of normal fetuses, applying the function y = k(MA)2 · e−a(MA) to the ultrasonographic data. With the use of this function it was possible to demonstrate that there are no significant differences in the pattern of fetal growth when a strict metabolic control is obtained in diabetic pregnant women.
