Objective: This thesis investigated the hearing status of neonates born to mothers with either gestational diabetes mellitus (GDM) or preexisting diabetes mellitus (DM). Past research has explored how metabolic alterations and other complications due to maternal diabetes affect neonates. However, few studies have examined the hearing status in infants born to diabetic mothers. Methods: Distortion product otoacoustic emission (DPOAE) data were gathered, bilaterally, at the frequencies of 2, 3, 4, and 5kHz from infants born to mothers with GDM and DM and from infants born to mothers without diabetes. A two-way analysis of variance for repeated measures was used on randomly selected ears to determine if there was between-group significance (control vs experimental) and/or a within subject (frequency) significance. All of the DPOAE amplitudes in each of the subjects were plotted against a range of normative data. Results: The results of the ANOVA suggest that there was not a significant group effect, and therefore no difference in DPOAE amplitudes were discovered between the control and the experimental group. A frequency effect was found to be significant but was influenced by the noise floor measures at the individual frequencies. The majority of the DPOAE amplitudes fell within a +/-2 standard deviation of the normative data. Discussion: There was no significant group difference for the DPOAE amplitudes. However, very low statistical power was observed for this between-group difference which could explain the insignificant findings. A trend for larger DPOAE amplitude in the infants of diabetic mothers was noted, and this same trend was discovered by Johnson (2000). Future studies should incorporate a larger population sample. Also, the noise levels should try to be controlled when conducting quantitative studies with DPOAEs as excessive noise levels may present as a confounding variable.
