International Conference on
Screening for gestational diabetes: Examining a breakfast meal test
Marais C
University of Stellenbosch, South Africa
Objective:
To compare a glucose test based on a standardized,
designed breakfast to the 75‐g oral glucose tolerance test
(OGTT), comparing venous and capillary glucose values for
the diagnosis of gestational diabetes mellitus (GDM).
Methods:
The present prospective, randomized, cross‐over
trial enrolled patients at high risk of developing GDM who
were attending the High‐Risk Antenatal Clinic of Tygerberg
Hospital, Cape Town, South Africa, between March 1 and
December 31, 2015. Patients were randomized to initial
testing with either the OGTT or a designed breakfast glucose
profile (DBGP) glucose test before the alternate test was
performed 1 week later; no dietary or other interventions
were applied in the intervening period. Venous and capillary
fasting and 2‐hour glucose values were measured and were
compared between the OGTT and DBGP, and between OGTT
and laboratory venous samples.
Results:
There were 51 patients included in the study. The
fasting and 2‐hour capillary glucose values from the OGTT
correlated significantly with the laboratory venous samples
(P<0.001 at both time intervals). The 2‐hour capillary glucose
values fromthe DBGP demonstrated a satisfactory correlation
with those from the OGTT (P<0.001).
Conclusions:
The DBGP provided a sufficiently accurate
alternate test for the diagnosis of GDM; it warrants further
investigation.
