Prevalence Of Newly Detected Diabetes In Pregnancy In Qatar, Using Universal Screening
PLOS ONE(2018)
Abstract
BackgroundDiabetes first detected during pregnancy is currently divided into gestational diabetes mellitus (GDM) and diabetes mellitus (DM)- most of which are type 2 DM (T2DM). This study aims to define the prevalence and outcomes of diabetes first detected in pregnancy based on 75-gram oral glucose tolerance test (OGTT)using the recent WHO/IADPSG guidelines in a high-risk population.MethodsThis is a retrospective study that included all patients who underwent a 75 g (OGTT between Jan 2016 and Apr 2016 and excluded patients with known pre-conception diabetes.ResultsThe overall prevalence of newly detected diabetes in pregnancy among the 2000 patients who fulfilled the inclusion/exclusion criteria was 24.0% (95% CI 22.1-25.9) of which T2DM was 2.5% (95% CI 1.9-3.3), and GDM was 21.5% (95% CI 19.7-23.3). The prevalence of newly detected diabetes in pregnancy was similar among the different ethnic groups.The T2DM group was older (mean age in years was 34 +/- 5.7 vs 31.7:6.7 vs 29.7 +/- 5.7, p<0.001); and has a higher mean BMI (32.4 +/- 6.4 kg/m2 vs 31.7 +/- 6.2 kg/m2 vs 29.7:6.2 kg/m2, p< 0.01) than the GDM and the non-DM groups, respectively. The frequency of preeclampsia, pre-term delivery, Caesarean-section, macrosomia, LGA and neonatal ICU admissions were significantly higher in the T2DM group compared to GDM and non-DM groups.ConclusionDiabetes first detected in pregnancy is equally prevalent among the various ethnic groups residing in Qatar. Newly detected T2DM carries a higher risk of poor pregnancy outcomes; stressing the importance of proper classification of cases of newly detected diabetes in pregnancy.
