ABSTRACT
Background: The aim of this study was to find role of SHBG as an early predictor for gestational diabetes mellitus.Methods: A hospital based prospective/observational/diagnostic and explorative study. The necessary information was collected from the participants through the prepared set of questionnaires. Pregnant women between 11 to 14 weeks of gestation who visited JSS OPD for antenatal checkup satisfying inclusion and exclusion criteria giving informed and written consent for the study were examined clinically. 3ml of venous blood was drawn with aseptic precautions for the estimation of SHBG and adiponectin. OGTT with 75gms glucose first done at 11 to 14weeks and again at 24-28 weeks and 32-36 weeks were done to the same patient to find out whether the patient developed GDM or not. These mothers were followed periodically till delivery. The sensitivity and specificity of SHBG were assessed and compared in patients who developed GDM.Results: 100 cases were selected for the study. About 12 patients were diagnosed as gestational diabetes mellitus in present study by OGCT at 32 weeks to 36 weeks. In present study about 14 patients had low level of SHBG. Low level of SHBG is found to be statistically significant in predicting GDM in first trimester.Conclusions: The combination of SHBG can be used as predictor of GDM in first trimester.
ABSTRACT
Anemia has been a very important nutritional disorder in the world. India has reported high prevalence of anemia in pregnancy. Most of the articles have reported an adverse pregnancy outcome related to anemia. Of late, reports are emerging suggesting anemia could be indeed beneficial. Apart from that, there was no consistency in the timing of hemoglobin considered for analysis. Hence, we designed an observational study to look into these aspects. 1000 mothers admitted for delivery were recruited and their hemoglobin was measured. Hemoglobin in previous trimesters was noted from their antenatal record. We followed up these mothers till delivery and looked into the gestation and birth weight of the babies. Descriptive statistics was used for baseline characteristics. Comparison of means was done using Student's t-test. Qualitative variables were compared using Fisher's exact test. More than 50% of the mothers were anemic at some point of time during their pregnancy and 39% of the mothers were anemic throughout. Mean birth weight of babies born to anemic mothers was marginally lower compared to that of babies born to nonanemic mothers. This difference was statistically significant. There was 6.5% increase in the incidence of low birth weight babies and 11.5% increase in preterm deliveries in mothers who were anemic in their third trimester. The incidence of low birth weight babies was significantly more in mothers who were anemic in their third trimester. Preterm deliveries occurred more frequently in mothers who were anemic in their second and third trimesters. Higher hemoglobin did not show any effect on either birth weight or gestation in our study
