Introduction:
The purposes of this study were to multidimensionally assess the voice in patients with type 2 diabetes using perceptual and acoustic measurements, laryngeal imaging, and patient self-assessment and compare it with the healthy control group.
Methods:
A total of 60 patients with type 2 diabetes were enrolled in this cross-sectional study, and a healthy group matched according to age and gender was recruited. The subjects underwent acoustic analysis using the Dysphonia Severity Index (DSI) and perceptual evaluation using the Persian version of the Consensus Auditory Perceptual Evaluation of Voice (ATSHA). Voice-related quality of life was assessed using the Voice Handicap Index (VHI).
Results:
In both patient and control groups, 28 male and 32 female participants, with a mean age range of 47.35 ± 9.49 and 44.18 ± 9.39 years old, were included. The patient group had a higher mean for ATSHA parameters compared to the control group, and the difference between these two groups was significant (p < 0.05). The VHI scores for the patient group were significantly higher than those for the control group. The mean of DSI scores was lower in the patient group; however, this difference was not statistically significant (p > 0.05). There was a statistically significant correlation among the DSI, FBS, and HbA1C variables (p = 0.007, r = -0.346, and p = 0.008, r = -0.337).
Conclusions:
The results confirm the presence of voice disorder symptoms in the patient group and their effects on their quality of life compared to the healthy group. These symptoms may result from changes in respiratory and muscle function, as well as changes in the phonetic mechanism of diabetes patients.
