主 题：Gestational Diabetes Oral Glucose Tolerance Test Sri Lanka Maternal and Perinatal Morbidity
摘 要：Aim: Evaluation of the occurrence of glucose intolerance after 34 - 36 weeks in pregnant mothers attending the Teaching Hospital, Peradeniya. Materials & Method: This is a descriptive cross-sectional study carried out from October 2017 to March 2018 among 183 pregnant mothers attending antenatal clinic at Teaching Hospital Peradeniya. After informed consent a repeat Oral Glucose Tolerance Test (OGTT) was done among the pregnant mothers, at period of amenorrhoea of 34 - 36 weeks, whose initial OGTT values were normal. Gestational diabetes was diagnosed according to the NICE guideline cut off values and the percentage of late occurrence of Gestational diabetes (GDM) was analyzed. Results: Mean age of the population was 29.1 years and the age range in this group was 18 to 45 years and the majority (73.9%) of women were primipara. There were 3.3% of teenage pregnancies and 14% of mothers were over 35 years. Majority (59.7%) of mothers underwent repeat OGTT test at 34 weeks of gestation and the rest (40.3%) underwent test between 34 to 36 weeks of gestation. Although the mean BMI was 23.74, 9.7% of mothers were obese (30 kg/m2), 30.3% of mothers were pre-obese (25.0 - 29.9 kg/m2). 8.2% of mothers were diagnosed with Gestational diabetes at 34 - 36 weeks whose initial OGTT values were normal. Conclusion: In view of reducing feto-maternal morbidity and mortality, considering a repeat OGTT at a later gestation (34 - 36 weeks of gestation) should be considered in mothers, whose initial OGTT values are normal as Sri Lanka is a high risk country for GDM. Clinical Significance: The study may play an important role in guideline alteration process and screening for gestational diabetes in Sri Lankan set-up.
