Is Early Diabetes Screening in Pregnancy Underutilized?

Obstet Gynecol; ePub 2017 Oct 6; Mission, et al

The use of early pregnancy diabetes screening is inconsistent, and many women with risk factors for diabetes do not undergo early screening, a recent study found. The retrospective cohort included all singleton deliveries from 2012 to 2014 among diverse clinical practices at a large academic medical center. Rates of early (<24 weeks of gestation) and routine (at or beyond 24 weeks of gestation) diabetes screening were assessed. Researchers found:

  • 1,420 of 11,331 (12.5%) women underwent early screening.
  • Increasing body mass index (BMI) category, race, history of gestational diabetes mellitus, family history of diabetes, and chronic hypertension were associated with early screening.
  • Early screening rates rose with increasing BMI category; however, only 48.6% of women with class III obesity underwent early screening.
  • Class III obese women had the highest percentage of abnormal early test results (9.0%).
