Association between isolated abnormal 1-hour glucose challenge test and adverse pregnancy outcomes: a retrospective review from an urban tertiary care center in the United States.

ABSTRACT:

Background

The objective of this study was to investigate whether an isolated abnormal 1-hour glucose challenge test (GCT) among patients without gestational diabetes (GDM) is associated with adverse outcomes.

Methods

This is a retrospective cohort study of patients who underwent GDM screening at ≥ 24 weeks' gestation with a 1-hour GCT and delivered a singleton fetus at > 35 weeks' gestation at an urban tertiary hospital from 1/2013 to 10/2021. Data were extracted from an electronic medical record data warehouse using standardized billing/diagnosis codes. Individuals were categorized into 3 groups: normal screening (1-hour GCT value < 140 mg/dL), intermediate screening (1-hour GCT value ≥ 140 and < 200 but normal 3-hour glucose tolerance test (GTT)), and GDM (1-hour GCT ≥ 20
