Women diagnosed with diabetes may be at a higher risk for requiring an intervention during delivery with a higher overall rate of caesarian sections and earlier deliveries compared with women without diabetes, according to a study published in Diabetologia.
Using the Scottish Morbidity Record, researchers identified 813,921 women who delivered a child during the 15-year time span observed in this study and analyzed data to compare perinatal outcomes in women with pregestational diabetes (n=4681), diabetes types 1 (n= 3229) and 2 (n=1452), and those without diabetes.
Study results found 104 perinatal deaths in total, with 65 deaths in children born to mothers with type 1 diabetes and 39 in women with type 2 diabetes, resulting in rates found to be 3.1 and 4.2 times higher than in women without diabetes (P <.001).
In women with type 1 and type 2 diabetes, researchers found the stillbirth rate to be 4.0- and 5.1-fold higher (P < .001) at average gestational ages of 33.6 and 34.1 weeks, respectively, compared with rates in women without diabetes.
Women diagnosed with diabetes types 1 and 2 were found to have a higher rate of delivery by cesarean section (67.7% and 59.6%, respectively), to deliver earlier (2.6 and 2 weeks, respectively), and to deliver preterm at a rate identified as 5-fold higher in women with type 1 diabetes. Further, infants born to mothers with types 1 diabetes and type 2 diabetes were large for gestational age at a rate of 51% and 38%, respectively.
Longitudinally, women with types 1 and type 2 diabetes were older (0.6 and 1.6 years, respectively), and had increased duration of diabetes…
