Risk factors associated with altered fetal growth in patients with pregestational diabetes mellitus.
2012
Objective: To assess the risk factors for abnormal fetal growth in patients with pregestational diabetic mellitus (DM). Methods: A retrospective study was performed in 336 patients with pregestational DM. Small-for-gestational-age (SGA) and large-for-gestational-age (LGA) infants were defined as newborns with birth weights 90th percentile, respectively. Logistic regression analysis was performed to identify risk factors for SGA and LGA. Results: Multivariate analysis of the patients with pregestational DM revealed a significant difference between patients who delivered SGA and appropriate-for-gestational-age (AGA) infants in terms of retinopathy (OR = 5.73, 95%CI = 1.39–23.59) and hemoglobin A1C (HbA1C) before delivery (OR = 0.80, 95%CI = 0.68 – 0.94, with a 0.1% increase in DCCT unit). Multivariate analysis revealed a significant difference between patients who delivered LGA and AGA infants in terms of primipara (OR = 3.40, 95%CI = 1.47–7.87) and HbA1C before delivery (OR = 1.14, ...
