Specific Objectives 1.To determine the prevalence of abnormal glucose tolerance (OGTT) among women with GDM at 6 weeks post partum 2.To determine association between pre pregnancy factors (i.e. age, race, educational level, occupation, pre pregnancy BMI, gravida, family history of DM, and abnormal OGTT at 6 weeks post partum, among GDM mothers 3. To identify association between pregnancy related factors (i.e. previous history of GDM, gestational age at the time of GDM diagnosis, HBA1c at diagnosis of GDM, OGTT 0 min and 120 during pregnancy, treatment with diet only, treatment with insulin, gestational week at start of insulin therapy, and abnormal OGTT at 6 weeks post partum among GDM mothers Content goes here… • Methodology • It was a prospective cohort study, conducted in Hospital UniversitiSains Malaysia (HUSM) from Feb 2010 till Nov 2010, involving 101 pregnant women diagnosed GDM who attended Antenatal Clinic, HUSM and fulfilled the inclusion and exclusion criteria. • Approved by the Research and Ethical Committee, School of Medical Sciences, USM on 20 Jan 2010. • Inclusion Criteria • GDM diagnosed during pregnancy • Exclusion Criteria • Established diabetes mellitus (Type 1 or Type 2) • Had other medical illness (e.g. HPT, HPL, cardiovascular • disease) • Flow Chart of the Study • . Figure 1: Prevalence of OGTT at 6 weeks post partum Table 1: Association between pre pregnancy related factors (occupation) and abnormal OGTT at 6 weeks post partum (simple logistic regression). (n=101) Backward LR method applied, Hosmer and Lemeshow test, p value = 1.00,Classification table 60.4% correctly classified, Area under Receiver Operating Characteristic (ROC) curve was 0.663 Table 2: Association between pregnancy related factors (HbA1C at diagnosis and mode of treatment) and abnormal OGTT at 6 weeks post partum (simple logistic regression). (n=101) Backward LR method applied, Hosmer and Lemeshow test, p value = 0.494, Classification table 60.4% correctly classified, Area under Receiver Operating Characteristic (ROC) curve was 0.795, No multicollinearity and no interaction found Table3: Association between pregnancy related factors (previous history of GDM, Gestational age at the time of GDM diagnosis) and abnormal OGTT at 6 weeks post partum ( multiple logistic regression). Backward LR method applied, Hosmer and Lemeshow test, p value = 0.971 Classification table 66.3% correctly classified, Area under Receiver Operating Characteristic (ROC) curve was 0.690, No multicollinearity and no interaction found Content goes here… • 1. The prevalence of abnormal glucose tolerance test at 6 weeks post partum was 39.6% including 35.64% of IGT and 3.96% of DM. • 2. Working status as a teacher was significantly associated with abnormal glucose tolerance at 6 weeks post partum by 3.5 times. • (adjusted OR=3.50;95%CI:1.33,9.26, p=0.011) • HbA1c at diagnosis of GDM was significantly associated with abnormal glucose tolerance at 6 weeks post partum. Women who had HBA1c of ≥ 6.5% has 3.88 times of having abnormal glucose tolerance as compared to women who had HBA1c of <6.5% . • (adjusted OR 3.88; 95% CI: 1.08, 13.99 ; p=0.038). • Insulin therapy was significantly associated with abnormal glucose tolerance at 6 weeks post partum. Women who are on insulin therapy has 5.34 times of having abnormal glucose tolerance as compared with women who are only on diet therapy • (adjusted OR=5.34; 95% CI 1.70, 16.76; p=0.004). • Previous history of GDM was significantly associated with abnormal glucose tolerance at 6 weeks post partum. Women with GDM on insulin who have previous history of GDM has 3.77 times odds of having abnormal glucose tolerance at 6 weeks post partum as compared with women who had no previous history of GDM. • (adjusted OR=3.77; 95% CI: 1.40, 10.17 ; p=0.009). • 6. Gestational age at the time of GDM diagnosis was significantly associated with abnormal glucose tolerance at 6 weeks post partum . The earlier the diagnosis of GDM, the higher the chances of having abnormal glucose tolerance at 6 weeks post partum. • (adjusted OR= 0.33; 95% CI: 0.12, 0.88; p=0.026). • Status of GDM • Previous history of GDM • Gestational age at the time of GDM diagnosis • HbA1c at the time of GDM diagnosis • FBS/OGTT during pregnancy • 2HPP/OGTT during pregnancy • Treatment with diet only • Treatment with insulin • Gestational week at start of insulin therapy • Socio demographic • Age • Race • Educational level • Occupation • Pre pregnancy BMI • Gravida • Family history of DM in first degree relative References 1.American Diabetes Association ( 2003).
