Prevalence of Gestational Diabetes and Pregnancy Outcome of antenatal patients in Ilorin.

Background: Gestational Diabetes mellitus (GDM) is fast becoming an important cause of maternal and perinatal morbidity and mortality. The objective of this study is to assess the prevalence and the perinatal outcome of gestational diabetes in an antenatal population.

Methodology: This was a cross-sectional study. The patients were pregnant women between 24-28 weeks of gestation without a prior diagnosis of diabetes mellitus. The consenting women were evaluated using fasting plasma glucose and oral glucose tolerance testing using 75 grams of glucose in 300ml of water orally.

Results: Two hundred and fifteen women participated in the study and the prevalence of GDM was 9%. The mean fasting plasma glucose was 4.04mmol/l at the time of the Oral glucose tolerance test (OGTT) and 5.78mmol/l after the oral glucose load. When compared with pregnant normoglycaemic patients, GDM patients had significantly fewer vaginal deliveries (p=0.05), higher birth weight (3.71kg), and more neonatal admissions (50%).

Conclusions: Gestational diabetes mellitus is an important disease entity, and it is a cause of maternal and perinatal morbidities.
