For diagnose of impaired glucose tolerance (IT) and gestational diabet
es (GD) we used oGTT as recommended WHO, which is applied between 20-2
8th weeks of gestation. We analyzed 124 pregnant women with IT and 34
pregnant women with GD. In the group of women younger than 20 years of
age, nine patients had IT; in those who were 20-24 years of age IT wa
s found in 14 patients and 5 patients had GD. In the third group which
consisted of those of 30-34 years of age 32 patients had IT and 5 pat
ients developed GD. In the older studied group (35-39 years of age) 14
patients had IT and one patient had GD. Increased incidence of IT and
GD was found in older pregnant patients. It is important to stress th
at 57% patients with IT and 57% patients with GD were less than 30 yea
rs old. It was not found any statistically significant difference in b
irthweight between patients who received insulin and who were on diet
only. The incidence of preterm deliveries was 13.9%. There was no stil
lbirth and neonatal death.
