Diabetes Technology in Pregnant Women with Type 1 Diabetes—Distribution and Effects on Glycemic Regulation and Perinatal Outcomes

Abstract

Pregnancies complicated by type 1 diabetes (TID) are associated with an increased risk of obstetric and neonatal adverse outcomes. Optimal glycemic control prior to and through pregnancy is crucial to reduce complications. The use of diabetes technology is rapidly increasing. The aim of the study was to investigate the use and effects of diabetes technology in pregnant women with type 1 diabetes. A retrospective cohort study was conducted; 84 women were included in the analysis and were divided into subgroups according to their glucose monitoring method and insulin delivery method. HbA1c values declined during pregnancy in all subgroups with no significant difference between the subgroups. A difference was, however, found in birth weight z-scores. Women using a sensor and an insulin pump had larger babies compared to women without these treatment modalities. The results of the study indicate that diabetes technology, including insulin pumps and/or glucose sensors are not superior to self-monitoring blood glucose measurement and multiple daily injection insulin therapy, which is comforting in the light of the unequal access to health benefits.
