Abstract
ObjectiveThis study aims to determine the association of gestational diabetes mellitus (GDM) and the results of newborn hearing screening(NHS). MethodsA nested case-control study was conducted in a cohort of newborns who were born between June 2021 to December 2021 and underwent neonatal hearing screening.GDM was diagnosed according to the 75 g 2 h oral glucose tolerance test (OGTT) at 24–28 gestational weeks.A total of 369 pregnant women at the same hospital were individually matched in a 1:2 ratio by maternal age (±2 years), gestational age (±3 days) and sex of newborn.Chi-square test was utilized to evaluate associations between GDM and the results of NHS. ResultsAbnormal NHS results in the GDM group was more frequent than non-GDM group.When comparing the two groups (GDM case and contol), we found significant differences (p < 0.05) between them.Whereas the difference was not statistically significant (p > 0.05) by delivery modes in both case and control groups. ConclusionMaternal history of GDM could lead to significantly higher failling rate of NHS.
