Clinical Analysis of 173 Cases of Gestational Diabetes Melu'tus

ve: To investigate the obstetric clinical manifestation and the incidence rate of gestational diabetes mellitus ( GDM). Methods; The obstetric clinical manifestations in 173 cases of GDM or pregnant women with diabetes mellitus (study group) diagnosed by the oral glucose tolerance test (OGTT) were compared with those in 144 normal pregnant women (control group ) during 1993 and 1999. The yearly incidence rate of GDM was retrospectively analyzed. Results: The incidence rates of pregnancy induced hypertension and postpartum hemorrhage were significantly higher in the study group (8.09% and 3.47% respectively) than those in the control group(2.08% and 0% respectively) (P0.05). The incidence rates of fetal macrosomia and fetal bodyweight 3.5 kg in the study group were 10.4% and 30.06% respectively, significantly higher than those in the control group ( 1. 39% and 27. 78% respectively) ( P 0. 05 ) . The incidence rate of GDM had a increasing tendency year by year, from 3.95% in 1995 to 8.78% in 1999 (P 0.05). Conclusion: GDM is a gestational complication harmful to pregnant women and perinatal foetus. Its incidence rate tends to increase in the recent years. Antenatal screening for GDM is necessary and control measures such as diet treatment should be taken.
