Gestational diabetes & diabetes in pregnancy

Glucose circadian rhythm assessment in pregnant women for gestational diabetes screening

Int J Obes (Lond)Published Prognostic modelling study

Authors' conclusion

Chronobiological parameters might contribute to a better identification of the adverse outcomes associated with GDM in both the mother and newborn.

Study context

Population
Pregnant patients with blinded Continuous Glucose Monitoring (CGM) data, assessed for gestational diabetes mellitus (GDM)-related adverse outcomes87 with enough data
Participants
92 patients
Outcome
Prediction of composite adverse neonatal outcomes by chronobiological variables from fitting glucose oscillation to a circadian rhythm
Methodological detailsblinded CGM
  • Blinded CGM

Performance

As reported in the abstract

Composite adverse neonatal outcomes
  • 3-covariate model (midline estimating statistic of rhythm (MESOR), glucose M10 start-time, age) was predictive of the primary outcome

Secondary outcomes

Maternal secondary outcomes

Model associated with preeclampsia with severe features and weight gain during pregnancy

Newborn secondary outcomes

Model associated with preterm delivery <37 weeks, indicated preterm delivery, NICU admission, need for CPAP and differences in hospital LOS
