OBJECTIVE To assess the relationship between second and third trimester glycemic control and adverse outcomes in pregnant women with type 1 diabetes, as uncertainty exists about optimum glycemic targets. RESEARCH DESIGN AND METHODS Pregnancy outcomes were assessed prospectively in 725 women with type 1 diabetes from the Diabetes and Pre-eclampsia Intervention Trial. HbA1c (A1C) values at 26 and 34 weeks’ gestation were categorized into five groups, the lowest, <6.0% (42 mmol/mol), being the reference. Average pre- and postprandial results from an eight-point capillary glucose profile the previous day were categorized into five groups, the lowest (preprandial <5.0 mmol/L and postprandial <6.0 mmol/L) being the reference. RESULTS An A1C of 6.0–6.4% (42–47 mmol/mol) at 26 weeks’ gestation was associated with a significantly increased risk of large for gestational age (LGA) (odds ratio 1.7 [95% CI 1.0–3.0]) and an A1C of 6.5–6.9% (48–52 mmol/mol) with a significantly increased risk of preterm delivery (odds ratio 2.5 [95% CI 1.3–4.8]), pre-eclampsia (4.3 [1.7–10.8]), need for a neonatal glucose infusion (2.9 [1.5–5.6]), and a composite adverse outcome (3.2 [1.3–8.0]). These risks increased progressively with increasing A1C. Results were similar at 34 weeks’ gestation. Glucose data showed less consistent trends, although the risk of a composite adverse outcome increased with preprandial glucose levels between 6.0 and 6.9 mmol/L at 34 weeks (3.3 [1.3–8.0]). CONCLUSIONS LGA increased significantly with an A1C =6.0 (42 mmol/mol) at 26 and 34 weeks' gestation and with other adverse outcomes with an A1C =6.5% (48 mmol/mol). The data suggest that there is clinical utility in regular measurement of A1C during pregnancy.
