Condition type 2 diabetes
Treatment oral glucose tolerance test 2 days post-partum

Collaborator The Lawson Foundation
Start date April 2014

Trial size 145 participants
Trial identifier NCT01869608, 13-005


Gestational diabetes mellitus (GDM) complicates 5 to 30 % of pregnancies. GDM is defined as hyperglycemia with onset or first recognition during pregnancy. Because it is a forerunner of type 2 diabetes mellitus (T2DM), professional associations recommend T2DM postpartum screening (T2DM-pPS) at 6 weeks/6 months post delivery, using a 75g oral glucose tolerance test (OGTT).

However, less than a quarter of these women are screened. This recommendation has failed for multiple reasons; the most important being that busy new mothers must deal with the major inconveniences of returning to a sampling center for a 2h testing session, bringing baby along or paying for a sitter, transportation, parking… A mother-friendly solution is direly needed.

The investigators hypothesize that, in these women, results of an OGTT performed after delivery on the last day of their hospital stay (OGTT-1) will predict results of the recommended OGTT (OGTT-2) at 6 weeks/6 months postpartum.

The main aim of our project is to determine the optimal cut-off value for the 2h glucose result during OGTT-1 in order to predict abnormal glucose tolerance status at OGTT-2 (the gold standard), in the same woman.
