A Clinical Study on Gestational Diabetes Mellitus and the Hearing of Newborns

This study aimed to explore the impact of gestational diabetes mellitus (GDM) on the results of newborn hearing screening.

A total of 666 pregnant women who gave birth in the Obstetric Department of Sunshine Ronghe Hospital from August 2017 to May 2018 were randomly selected, and 69 of these pregnant women had GDM and were assigned into group 1 (excluding other diseases). The average age of these patients was 31.07 years. A further 597 pregnant women had no GDM and were assigned into group 2 (excluding other diseases). The average age of these patients was 30.02 years. The results of newborn hearing screening results in group 1 and group 2 were compared.

Comparisons of abnormal hearing screening between 2 groups are significant different (P < 0.05). In the GDM group, the results of hearing screening of newborns delivered by vaginal delivery and cesarean delivery were compared, yielding a P-value of > 0.05, and the difference was not statistically significant. In the non-GDM group, the results of hearing screening of newborns delivered by vaginal delivery and cesarean delivery were compared, yielding a P-value of >0.05, and the difference was not statistically significant.

GDM increases the incidence of abnormal hearing in newborns.
