Results
1949 women met inclusion criteria, 78 (4%) had eLGA (study group) and
1871 (96%) controls (figure 1).
Women in the study group were older (35 (31.7-37.0) vs. 33 (30.0-36.0)
years; p=0.004), with higher BMI (30.9 (IQR27.7-33.3) vs. 27.5
(25.1-30.5) kg/m²; p=0.001) and higher gravidity (4 (3-6 ) vs. 3 (2-4);
p=0.001) compared to the controls. Women’s demographics and
characteristics are summarized in table 1.
The median Glucose challenge test (GCT) value was 105 (IQR 89-127)
vs.106 (91-121) mg/dl for the study group and controls, respectively
(p=0.97). Gestational diabetes was 12.5% in the study group compared to
14.9% in the controls (p=0.68). Median gestational age at birth was
39.3 for both groups. Estimated fetal weight was higher in the study
group as expected [3900 (3800-4040) vs. 3200 (3050-3500) g;
p=0.001], as well as neonatal weight [3887 (3718-4073) vs. 3275
(2995-3545) g; p=0.031].
The rate of successful vaginal delivery was lower in the study group
70.5% (55/78) compared to 80.5% (1506/1871) in the controls (p= 0.03).
No significant difference in the rate of scar dehiscence, uterine
rupture, 3rd /4th degree perineal
tear and shoulder dystocia was found between the groups. However, the
rate of post-partum hemorrhage was increased in the study group compared
to controls (7.7 vs.1.7%; p=0.001), with no difference in blood
transfusion rate (Table 2).
