RESUMO
The aim of study was to evaluate incidence of GDM in Poland. All 1500 pregnant women between 24-28 week's gestation consulted in 4 centers were offered a 50 g oral glucose test (screening test). Capillary blood glucose was measured at 60 min after glucose ingestion. When blood glucose > 140 mg/dl, 75 g OGTT according to WHO criteria was performed. 241 women have abnormal screening test and in 181 cases blood glucose were at range 140-160 mg/dl, in 39 at range 160-180 and 21 were > 180 mg/dl. Only 14 women in the first group (140-160 mg/dl) have diagnosed GDM (7.7%). In second group 24 pregnant women have GDM (61.5%). Overall GDM incidence is shown to be 3.7% (57 women). The mean age for the GDM was 28.8 +/- 0.9 years compared with 26.4 +/- 0.4 years (p < 0.05) uncomplicated pregnancy.
