Risk of Neonatal Hypoglycemia in Infants of Mothers With Gestational Glucose Intolerance

Diabetes CarePublished Secondary analysis of a cohort of mother-infant dyads

Authors' conclusion

GGI is associated with increased risk of neonatal hypoglycemia. Future research should include examination of these associations in a cohort with more complete neonatal blood glucose ascertainment and determination of the clinical significance of these findings on long-term child health.

Study context

Population
Mother-infant dyads delivered at two hospitals, 2014–2023
Participants
8,262 mother-infant dyads
Comparison
Maternal GGI-0, GGI-1 or GDM vs normal glucose tolerance (NGT)
Primary endpoint
Neonatal hypoglycemia (blood glucose <45 mg/dL or ICD-9/ICD-10 diagnosis)
Methodological detailstwo hospitals, logistic regression, sensitivity analysis using Δ-adjusted multiple imputation
  • Two hospitals
  • Logistic regression
  • Sensitivity analysis using Δ-adjusted multiple imputation

Primary result

As reported in the abstract

Neonatal hypoglycemia
Each group vs NGTAdjusted odds ratio (95% CI)
GGI-0
1.28(1.12–1.65)
GGI-1
1.58(1.11–2.25)
GDM
4.90(3.81–6.29)
Infants with neonatal hypoglycemia (all infants)
12%

Further findings

Sensitivity analysis (Δ-adjusted multiple imputation, assumed rate up to 33% in unscreened infants)

Associations consistent with the primary analysis
