AimsTo determine the preferred method of screening for gestational diabetes mellitus (GDM).Methods1804 women from a prospective study (NCT02036619) received a glucose challenge test (GCT) and 75g oral glucose tolerance test (OGTT) between 24-28 weeks. Tolerance of screening tests and preference for screening strategy (two-step screening strategy with GCT compared to one-step screening strategy with OGTT) were evaluated by a self-designed questionnaire at the time of the GCT and OGTT.ResultsCompared to women who preferred one-step screening [26.2% (472)], women who preferred two-step screening [46.3% (834)] were less often from a minor ethnic background [6.0% (50) vs. 10.7% (50), p=0.003], had less often a previous history of GDM [7.3% (29) vs. 13.8% (32), p=0.008], were less often overweight or obese [respectively 23.1% (50) vs. 24.8% (116), p<0.001 and 7.9% (66) vs. 18.2% (85), p<0.001], were less insulin resistant in early pregnancy (HOMA-IR 8.9 (6.4-12.3) vs. 9.9 (7.2-14.2), p<0.001], and pregnancy outcomes were similar except for fewer labor inductions and emergency cesarean sections [respectively 26.6% (198) vs. 32.5% (137), p=0.031 and 8.2% (68) vs. 13.0% (61), p=0.005]. Women who preferred two-step screening had more often complaints of the OGTT compared to women who preferred one-step screening [50.4% (420) vs. 40.3% (190), p<0.001].ConclusionsA two-step GDM screening involving a GCT and subsequent OGTT is the preferred GDM screening strategy. Women with a more adverse metabolic profile preferred one-step screening with OGTT while women preferring two-step screening had a better metabolic profile and more discomfort of the OGTT. The preference for the GDM screening method is in line with the recommended Flemish modified two-step screening method, in which women at higher risk for GDM are recommended a one-step screening strategy with an OGTT, while women without these risk factors, are offered a two-step screening strategy with GCT.Clinical Trial RegistrationNCT02036619 https://clinicaltrials.gov/ct2/show/NCT02036619

Abstract Screening for gestational diabetes mellitus (GDM) is internationally recommended however there is no universal approach. Impact of the different diagnostic strategies on maternal and neonatal complications’ rates and cost-effectiveness need to be studied. Objective To compare maternal and neonatal outcomes between the two supported screening methods for GDM; the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) 75g one-step oral glucose tolerance test (OGTT) versus the 50g two-step OGTT. Methods A retrospective cohort study was performed regrouping all deliveries between 2016 and 2018 in two centers, each using one different screening method. GDM was diagnosed in center A when meeting IADPSG odds ratio (OR) 1.75 cut-offs values after a one-step 75g-OGTT. Center B used a two-step strategy and diagnosed GDM with 50g-OGTT 1hr glycemic value ≥11.1 mmol/L or failed 50g followed by 75g-OGTT results over the IADPSG OR 2.0 cut-offs. Primary outcome was the rate of large for gestational age (LGA) babies. Outcomes were analysed for singleton pregnancies with deliveries >32 weeks. Subgroup analysis of borderline GDM women (OGTT results in between IADPSG OR 1.75 and 2.0 values) were done. Group A’s borderline patients were treated as per GDM patients. Group B’s borderline patients were not considered diabetic and had normal pregnancy care. Results were adjusted for maternal age, BMI and gestational weight gain. Results At interim analysis for the year 2016, a total of 6188 pregnancies, 2664 women in center A (one-step) and 3524 in center B (two-step) were included. The prevalence of GDM was 17.1% in center A (n=456) and 14.8% in center B (n=520). Both populations were comparable in terms of risk factors for LGA except for its ethnic distribution and proportion of obese women (13.1 vs 21.6%). GDM women in center B compared to center A had significant increase in rates of LGA neonates (adjusted OR (ORa) 2.1, p=0.012); neonatal hypoglycemia (ORa 2.1, p=0.0001) and neonatal intensive care unit (NICU) admission (2.1, p=0.048). Gestational hypertension’s rate was more prevalent in center B (ORa 2.1, p=0.020) and there was a non statistical trend towards increased rate of caesareans (1.6, p=0.084). Regular prenatal care for borderline women in center B (n=94) compared to GDM care in center A (n=150) resulted in increased rate of LGA babies (ORa 3.2, p=0.049). Worse maternal outcomes were identified for gestational hypertension (9.7 vs 1.3%, p=0.035) and preeclampsia (4.3 vs 0%, p=0.021) in group B vs A, respectively. Conclusions Choosing the one-step IADPSG criteria’s for GDM screening is associated with lower rates of LGA, neonatal hypoglycemia and NICU admissions, at the expense of increased prevalence in our population. The ongoing study will include a cost-benefit evaluation to assess if improved outcomes overbalance the increased prevalence inherent to lower diagnostic criteria.

Background: To screen patients at average risk for Gestational Diabetes using 50g Glucose Challenge test, to ascertain the prevalence of Gestational diabetes through further diagnostic testing and to prevent and manage complications. Gestational diabetes mellitus (GDM) is defined as carbohydrate intolerance of variable severity with onset or first recognition during pregnancy. Women with GDM are at risk for maternal and foetal complications, so it is important to screen all the pregnant woman.Methods: This study was conducted in 198 patients between 24 and 28 weeks of gestation, attending the Antenatal clinic. 50g oral glucose is administered irrespective of time of the last meal and plasma glucose is measured one hour later. Patients with plasma glucose levels more than 140 mg/dl were subjected to a 100g oral glucose tolerance test, patients with two or more abnormal reading were labelled as GDM and managed accordingly.Results: Prevalence of GDM in our study was 9.59%. Maternal complications like gestational hypertension, vaginal infections and foetal complications were much higher in GDM patients as compare to non GDM group.Conclusions: GDM is a disease which adversely affects both mother as well as foetus. It is concluded that 50 gm glucose challenge test at 24-28 weeks of gestation with a cut-off value of 140 mg/dl is a reliable screening test for GDM. This test offers the best combination of ease and economy of use and reproducibility in screening for gestational diabetes mellitus in average risk patients.

Abstract Background There is still no worldwide agreement on the best diagnostic thresholds to define gestational diabetes (GDM) or the optimal approach for identifying women with GDM. Should all pregnant women perform an oral glucose tolerance test (OGTT) or can easily available maternal characteristics, such as age, BMI and ethnicity, indicate which women to test? The aim of this study was to assess the prevalence of GDM by three diagnostic criteria and the predictive accuracy of commonly used risk factors. Methods We merged data from four Norwegian cohorts (2002–2013), encompassing 2981 women with complete results from a universally offered OGTT. Prevalences were estimated based on the following diagnostic criteria: 1999WHO (fasting plasma glucose (FPG) ≥7.0 or 2-h glucose ≥7.8 mmol/L), 2013WHO (FPG ≥5.1 or 2-h glucose ≥8.5 mmol/L), and 2017Norwegian (FPG ≥5.3 or 2-h glucose ≥9 mmol/L). Multiple logistic regression models examined associations between GDM and maternal factors. We applied the 2013WHO and 2017Norwegian criteria to evaluate the performance of different thresholds of age and BMI. Results The prevalence of GDM was 10.7, 16.9 and 10.3%, applying the 1999WHO, 2013WHO, and the 2017Norwegian criteria, respectively, but was higher for women with non-European background when compared to European women (14.5 vs 10.2%, 37.7 vs 13.8% and 27.0 vs 7.8%). While advancing age and elevated BMI increased the risk of GDM, no risk factors, isolated or in combination, could identify more than 80% of women with GDM by the latter two diagnostic criteria, unless at least 70–80% of women were offered an OGTT. Using the 2017Norwegian criteria, the combination “age≥25 years or BMI≥25 kg/m2” achieved the highest sensitivity (96.5%) with an OGTT required for 93% of European women. The predictive accuracy of risk factors for identifying GDM was even lower for non-European women. Conclusions The prevalence of GDM was similar using the 1999WHO and 2017Norwegian criteria, but substantially higher with the 2013WHO criteria, in particular for ethnic non-European women. Using clinical risk factors such as age and BMI is a poor pre-diagnostic screening method, as this approach failed to identify a substantial proportion of women with GDM unless at least 70–80% were tested.

Abstract Objectives To evaluate whether gestational diabetes mellitus (GDM) diagnosed by different criteria impacts perinatal outcome. Methods This was a retrospective study of deliveries with a diagnosis of GDM (2014–2016). Perinatal outcomes were compared between patients with: (1) GDM diagnosed according to a single abnormal value on the 100-g oral glucose tolerance test (OGTT); (2) two or more abnormal OGTT values; and (3) a 50-g glucose challenge test (GCT) value ≥200 mg/dL. Results A total of 1163 women met the inclusion criteria, of whom 441 (37.9%) were diagnosed according to a single abnormal OGTT value, 627 (53.9%) had two or more abnormal OGTT values and 95 (8.17%) had a GCT value ≥200 mg/dL. Diet-only treatment was significantly higher in the single abnormal value group (70.3% vs. 65.1% vs. 50.5%) and rates of medical treatment were significantly higher in the GCT ≥ 200 mg/dL group (P < 0.05). Women in the GCT ≥ 200 mg/dL group had higher rates of neonatal intensive care unit (NICU) admission (10.5% vs. 2.7% vs. 2.8%, P < 0.001) and neonatal hypoglycemia (5.3% vs. 0.5% vs. 0.8%, P < 0.001). On multivariate logistic regression, GCT ≥ 200 mg/dL was no longer associated with higher rates of NICU admission and neonatal hypoglycemia (P > 0.05). Conclusion No difference was noted in the perinatal outcome amongst the different methods used for diagnosing GDM.

Aim: The Diabetes in Pregnancy Study Group of India (DIPSI, 2010) guidelines recommend the non-fasting 75-g oral glucose challenge test (OGCT) as a single-step screening and diagnostic test for gestational diabetes mellitus (GDM). The aim of this study was to assess the validity of DIPSI criteria by comparing with the World Health Organization (WHO) 1999 criteria of diagnosing GDM. Methods: This study was a hospital based prospective comparative study conducted among 282 pregnant women, of gestational age of 24-28 weeks attending antenatal OPD of Patan hospital. The OGCT was performed on them irrespective of fasting state and without any dietary preparation and they were again asked to come after 3 days of unrestricted carbohydrate diet in fasting state for WHO 2-hour oral glucose tolerance test (OGTT) with 75 gram of glucose load. The value of OGCT >140 mg/dl is diagnostic of GDM (DIPSI 2010). For the reliability of this test, it was compared with WHO 2-hour OGTT. Results: Among the study population, the mean age and BMI was 26.04±4.50 and 24.08±3.30 respectively. Out of 282 patients, 8 cases (2.83%) were found to have abnormal non-fasting 75-g OGCT and 4 cases (1.41%) had abnormal WHO 2-hour OGTT. Paired t test was employed to examine the difference of blood glucose level of the tests. There was statistically significant difference (p<0.001) between the tests. The Sensitivity, specificity, positive predictive value and negative predictive value of oral glucose challenge test was 25%, 97.48%, 12.5% and 98.90% respectively. The non- fasting 75-g OGCT was able to detect only 25% of the cases. Conclusions: Though the non-fasting 75-g OGCT test is cost effective and more compliant to pregnant women, the present report suggests that it cannot be used as a single step screening and diagnostic test because of its low sensitivity. However, it is an adequate alternative for screening test in resources limited areas.

Introduction: Diabetes has become a significant health problem all over the world and its prevalence is increasing rapidly, including in Nepal. Prevalence of gestational diabetes mellitus (GDM) is directly related to the prevalence of type 2 diabetes. Women who areoverweight or obese before they become pregnant are more at risk of GDM irrespective of other factors.Though the risk of developing GDM in shown to be higher in overweight or obese women, there are very few studies done to show such observation in the urban population of Nepal.Methods: This was a hospital based cross-sectional prospective study conducted among the women attending ante partum clinic, in a tertiary level hospital, located at Lalitpur for one-year duration in 2009. All overweight (pre-pregnancy body mass index (BMI)>23) urban women at 24-28 weeks of gestation were enrolled.Fasting blood glucose, screening 50-g oral glucose challenge test(OGTT) and 2-hr OGTT following overnight fastingwas done as per need based on their test results and GDM was diagnosed based on standard guidelines.Results: Out of 256 women majority of women had BMI >25 kg/m2 (n=180),and 151(59%) were multiparous and 105 (41%) were primiparas. Positive screening test was obtained in 51 women (19.9%).The incidence of GDM by ADA and WHO criteria was 10 (3.9%) and 16 (6.3%) respectively. There was statistically non-significant difference in the rate of positive screening test and BMI (p=0.09). The abnormal screening test between primiparous and multiparous was significant (p=0.01).Conclusion: This study showed a high pre-pregnancy BMI and the incidence of GDMamong the patients enrolled. The rate of positive screening test is also higher than the previous studies so, GDM is a growing issue and must be well addressed.

OBJECTIVE: The aim of this study was to investigate whether minor abnormalities of glucose metabolism without gestational diabetes are a risk factor for fetal overgrowth. DESIGN: A sample of 1883 unselected white mother-infant pairs were screened for gestational diabetes using a 50 g 1-h oral glucose challenge test (GCT) in two periods of pregnancy: early (16-20 weeks) and late (26-30 weeks). METHODS: The effects of risk factors (glucose metabolism, previous history of mothers, obesity, multiparity and age of mothers) were estimated using a multinomial logit model. RESULTS: The level of risk was related to gestational age at the appearance of an abnormal GCT. Patients with an abnormal GCT in the early and late periods of pregnancy (Group 1) had a risk of delivering a large for gestational age (LGA) infant seven times higher than the control group (normal GCT in both periods), and patients with a normal GCT in the early period and an abnormal GCT in the late period (Group 2) showed a risk three times higher than the control group. Among the historical risk factors for LGA infants, such as maternal obesity, multiparity, previous gestational diabetes and previous delivery of an infant weighing 4000 g or more, only the latter was associated with fetal overgrowth with a risk level 4.7 higher than the control group. Group 1 patients had a significantly higher incidence of pregnancy-induced hypertension and preterm birth. There were no differences in the frequency of 5-min Apgar score < 7 and metabolic complications among the infants of all groups. We found a significantly higher rate of shoulder dystocia in Group 1 infants than in infants in the other groups. CONCLUSIONS: Our results suggest that a positive GCT at 26-30 weeks is the most important risk factor for fetal overgrowth. This result was strongly enforced in patients who had also shown a positive early GCT at 16-20 weeks.
