Previous non-diabetic pregnancy with a macrosomic infant – Is it a risk factor for subsequent gestational diabetes mellitus?

Background: Gestational diabetes mellitus (GDM) is a common cause of hyperglycaemia in pregnancy accounting for about 90% of all diabetic pregnancies. Women with GDM are at increased risk of maternal and fetal morbidity and mortality which are preventable through early diagnosis and treatment. Objective: The aim was to determine the prevalence of GDM, compare the maternal and neonatal complications among GDM and non-GDM pregnant women, and the risk factors associated with GDM. Methodology: A prospective cohort study was carried out among 105 pregnant women attending the antenatal clinic of RSUTH between February and August 2017. They were interviewed using a pre-structured questionnaire that covered variables related to socio-demographic factors and family, medical, and social history. Fasting blood sugar (FBS) was done after an overnight fast. Women who had FBS less than 7 mmol/L had 75 g Oral Glucose Tolerant Test (OGTT) done. Those diagnosed with gestational diabetes mellitus were the exposed group while those negative for GDM were the non-exposed group. Both groups were followed up to delivery, and maternal and fetal outcomes were noted. Statistical analysis was carried out using SPSS version 20 and significance set at p < 0.05. Results: The prevalence of GDM was 10.5%. Positive history of GDM in previous pregnancy was the only independent risk factor (p=0.04, Adj OR: 26.89, 95% CI 2.86 to 252.61). GDM mothers had a significantly higher risk of developing pre-eclampsia (RR=7.48; 95% CI =3.36 to 16.63). Neonates of GDM mothers were at increased risk of fetal macrosomia (RR =9.00; 95% CI=1.36 to 59.4) and neonatal admissions (RR=8.00; C.I =1.19 to 53.67). Conclusion: The study revealed that the prevalence of GDM was high and that those with GDM were at increased risk of developing fetal and maternal complications. A history of GDM in previous pregnancy was an essential risk factor for subsequent GDM.

Background: Gestational diabetes mellitus (GDM) is the most common medical complication and metabolic disorder of pregnancy. The aim and objective of this study was to determine the prevalence of GDM and its relationship with various risk factors with special reference to tribal population.Methods: The study was done in 200 patients between 24 and 28 weeks of gestation, attending antenatal outdoor in a tertiary care hospital of West Bengal. These patients were given 75gm oral glucose irrespective of the last meal and their plasma glucose was estimated at 2hours. Patients with plasma glucose values ≥140 mg/dl were labelled as GDM. Patients who were diabetic before pregnancy or whose pre pregnancy body mass index was not known or was in labour or had chronic disease, were not included in the study.Results: Prevalence of GDM was 11% in whole population while it was 14.63% and 10.06% in tribal and non-tribal population respectively. Prevalence of GDM and its correlation with most of risk factors in previous pregnancies was found to be significant in both non-tribal and tribal population. Family history of diabetes mellitus was the most prevalent risk factor in both non-tribal (9.4%) and tribal population (14.63%). There was no single most common risk factor among GDM patients found as there were multiple risk factors present with same frequency in both tribal and non-tribal population.Conclusions: The prevalence of GDM is 14.63% in the tribal population and 10.06% in non-tribal population which is not statically significant (P<0.407). The relation between the prevalence of GDM and risk factors was found to be significant for most of the risk factors.
