ABSTRACT The aim of this study was to determine the relevance of universal screening for gestational diabetes mellitus (GDM) in the patients attending the antenatal clinic of a tertiary institute of North India.
This was a prospective study conducted on 700 pregnant women attending the antenatal clinic of Lok Nayak Hospital, New Delhi at or before 24 weeks of gestation. All patients underwent screening with a 50-g 1-h glucose challenge test at 24-28 weeks of gestation. The women with an abnormal glucose challenge test subsequently underwent a diagnostic 3-h oral glucose tolerance test. All the patients were followed up till delivery.
Out of 700, thirteen patients were lost to follow up and hence the final outcomes were measured on 687 patients. Out of 687, 613 patients (89.2%) had a normal glucose challenge test value, that is, <140 mg%, and 74 (10.8%) had a glucose challenge test value ≥140 mg%. On the subsequent oral glucose tolerance test, 64 (9.3%) had normal values and only 10 (1.5%) had an abnormal oral glucose tolerance test, that is, GDM.
With such a low prevalence rate it appears to be unjustified to recommend universal screening for GDM. These findings may be considered as a basis for conducting larger, multicentric studies to establish the prevalence rate of GDM before deciding on a policy for screening.

    ABSTRACT: Background: Little is known about the burden of diabetes mellitus (DM) in pregnancy in low- and middle-income countries despite high prevalence and mortality rates being observed in these countries. Objective: To investigate the prevalence and geographical patterns of DM in pregnancy up to 1 year post-delivery in low- and middle-income countries. Search strategy: Medline, Embase, Cochrane (Central), Cinahl and CAB databases were searched with no date restrictions. Selection criteria: Articles assessing the prevalence of gestational diabetes mellitus (GDM), and types 1 and 2 DM were sought. Data collection and analysis: Articles were independently screened by at least two reviewers. Forest plots were used to present prevalence rates and linear trends calculated by linear regression where appropriate. Main results: A total of 45 articles were included. The prevalence of GDM varied. Diagnosis was made by the American Diabetes Association criteria (1.50-15.5%), the Australian Diabetes in Pregnancy Society criteria (20.8%), the Diabetes in Pregnancy Study Group India criteria (13.4%), the European Association for the Study of Diabetes criteria (1.6%), the International Association of Diabetes and Pregnancy Study Groups criteria (8.9-20.4%), the National Diabetes Data Group criteria (0.56-6.30%) and the World Health Organization criteria (0.4-24.3%). Vietnam, India and Cuba had the highest prevalence rates. Types 1 and 2 DM were less often reported. Reports of maternal mortality due to DM were not found. No geographical patterns of the prevalence of GDM could be confirmed but data from Africa is particularly limited. Conclusion: Existing published data are insufficient to build a clear picture of the burden and distribution of DM in pregnancy in low- and middle-income countries. Consensus on a common diagnostic criterion for GDM is needed. Type 1 and 2 DM in pregnancy and postpartum DM are other neglected areas.

    ABSTRACT: The carbohydrate 'fuel' metabolism in a pregnant woman may have a long-term impact on the development of her offspring ('fuel-mediated teratogenesis' hypothesis) including in utero exposure to maternal hyperglycaemia leading to fetal hyperinsulinaemia, and the consequent increase in fetal fat cells. Therefore, a feed-forward loop can exist of rising adiposity and hyperinsulinaemia throughout childhood, perhaps leading to obesity and diabetes in later life. There is a need for prospective examination of body fat distribution in children born to mothers with different glycaemic levels to understand the plausible association between glucose metabolism and future risk of diabetes in offspring. The hypothesis is that maternal glucose levels in pregnant women are related to skinfold thickness in their infants.

    ABSTRACT: The aim and objective was to study the prevalence of gestational diabetes mellitus (GDM) by using National Diabetes Data Group (NDDG) and American Diabetes Association (ADA) (2004) criteria and the correlation of GDM with gestational blood pressure (BP) and maternal age. This was a cross-sectional study in which 300 pregnant women in 24-28 weeks of pregnancy who screened positive with 1-h glucose load ≥ 140 mg/dL underwent a diagnostic 3-h oral glucose tolerance test (OGTT). BP was obtained by review of the medical records. Thirty-seven (12.33%) women were screened positive with 50 g glucose challenge test (GCT) (≥140 mg%) out of the 300 participants. With 100 g 3-h OGTT among these 37 women, none of them fulfilled the NDDG diagnostic criteria for GDM. However, on using the ADA (2004) criteria, three (8.1%) women were diagnosed to have GDM. All three of them had systolic BP between 120 and 139 mmHg; two of them had diastolic BP between 80 and 89 mmHg. Among 37 subjects with GCT > 140 mg%, majority were older than 26 years. Using the ADA (2004) guideline, 1% of the total study population had GDM. The BP of these patients fell within the prehypertensive range, thus suggesting an association between GDM and BP.
