Gestational Diabetes Prevalence Estimates from Three Data Sources, 2018

Abstract

Introduction: We investigated 2018 gestational diabetes mellitus (GDM) prevalence estimates in three surveillance systems (National Vital Statistics System, State Inpatient Database, and Pregnancy Risk Assessment Monitoring Survey). Methods: We calculated GDM prevalence for jurisdictions represented in each system; a subset of data was analyzed for people 18–39 years old in 22 jurisdictions present in all three systems to observe dataset-specific demographics and GDM prevalence using comparable categories. Results: GDM prevalence estimates varied widely by data system and within the data subset despite comparable demographics. Discussion: Understanding the differences between GDM surveillance data systems can help researchers better identify people and places at higher risk of GDM.
