Abstract
- Type 1 diabetes (T1D) in pregnancy is associated with increased neonatal morbidity, which improves with optimal glycemic control. Aim: To compare lab and CGM glucose summary measures as predictors of neonatal outcomes in T1D pregnancy. Methods: 225 CONCEPTT participants had 6-day CGM and blood analysis of glycemic markers in 1st trimester, 24 and 34 weeks (Average glucose; % time in target 63-140 mg/dl, coefficient of variation (CV)); HbA1c; glycated CD59 (gCD59); 1,5-anhydroglucitol (1,5AG); glycated albumin). Outcomes: large for gestational age (LGA), neonatal hypoglycemia (NH) and neonatal intensive care unit (NICU) admission. Statistics: Unadjusted logistic regression. Results: All glucose summary measures excluding CV predicted neonatal outcomes (Table). Glycemic control at all timepoints from 1st trimester was important for LGA, but emerged later for NH (24 and 34 weeks) and NICU (mainly 24 weeks). Both CGM time in target and average glucose and lab markers HbA1c, 1,5AG and gCD59 predicted all three outcomes studied. Time in target was the best CGM predictor. The best lab predictors were HbA1c, 1,5AG and gCD59. HbA1c was the strongest predictor of LGA and NH, but only predicted NICU admission late in pregnancy. Conclusions: In women with T1D, both CGM and lab glucose summary measures can predict neonatal outcomes from 1st trimester. Disclosure: C.L. Meek: None. D. Tundidor: None. H.R.
