Gestational Diabetes in Mid-trimester Pregnancy in South Asian Women Based on the Oral Glucose Challenge Test and Risk Factor Predictors: A Prospective Observational Study
Introduction: Gestational Diabetes Mellitus (GDM) is a condition potentially occurring during pregnancy. It is associated with adverse foetal and maternal outcomes and is particularly prevalent in South Asian women who comprised this study sample. Aim: To provide a critical analysis of the infor...

Introduction: Gestational Diabetes Mellitus (GDM) is a condition
potentially occurring during pregnancy. It is associated with
adverse foetal and maternal outcomes and is particularly prevalent
in South Asian women who comprised this study sample.
Aim: To provide a critical analysis of the information on GDM
risk that can be identified from screening using the Oral Glucose
Challenge Test (OGCT-50 g).
Materials and Methods: A prospective cohort study was conducted
over eight months. Purposive sampling was used to collect
demographic and clinical data {age; Body mass Index (BMI);
parity; history of Diabetes Mellitus (DM) in a first degree
relative and histories of GDM, polyhydramnious, macrosomia,
birth congenital abnormalities and still birth} from 300 South
Asian women in mid-trimester pregnancy who consented to
undertake an OGCT-50g. Excluded were primigravidas, women
with DM or other medical conditions, and women who were
unwilling or unable to give informed written consent. Descriptive,
comparative and multivariate logistic analyses were used to
investigate strengths of correlation between OGCT outcomes
and clinical/historical risk factors.
Results: The OGCT were 107 (35.7%) positive and 193 (64.3%)
negative. The threshold for body mass risk was identified as
27.5 kg/m2
. Women with two or more risk factors were OGCT
positive on 72.9% occasions whereas women with one or no risk
factor were OGCT negative on 81.9% occasions. Approximately,
50% of women had a family history of DM as their only risk
factor and 24% of them were OGCT positive.
Conclusion: The BMI was the strongest determinant of a positive
OGCT result. The logistic regression analysis demonstrated that
using the lower BMI threshold of 27.5 compared to 30.0 [as
per National Institute for Health and Care Excellence (NICE)
guideline] improved agreement between risk factors profile was
assessed and OGCT results. |
