Abstract

This is a retrospective analysis of mothers with abnormal 1-hour, 50-grams glucose challenge test (GCT) who did not take a 3-hour, 100-gram oral glucose tolerance test (OGTT). This study group of women was compared to three control groups, based on an OGTT diagnostic test- normal OGTT, single pathological value and gestational diabetes mellitus. Overall- 4,185 women were included and sub-divided accordingly into four groups: Group A-340 (8.12%)- no OGTT; Group B-2,585 (61.77%)- Norm OGTT (All values normal); Group C- 564 (13.48%)- SinOGTT (single pathological value) and Group D- 696 (16.63%)- Gestational Diabetes Mellitus (GDM, ≥ 2 pathological values). Groups A, C and D had higher rates of intrapartum Caesarean Delivery (10.29%, 11.52% and 10.19% vs. 8.43%,
