KADINLARDA AKUSTİK VE ELEKTROGLOTTOGRAFİK PARAMETRELERİN VÜCUT KİTLE İNDEKSİ BAKIMINDAN İNCELENMESİ

Abstract

Aim: The aim of this study is to examine the relationships between Multi-Dimensional Voice Program (MDVP) and Electroglottograph (EGG) measurement results of female individuals that are grouped according to their body mass index (BMI). Material and Methods: 96 women who are at the ages between 18-25 have participated.Participants were divided into 4 BMI groups; weak (n=20), normal (n=29), overweight (n=22) and obese (n=21). Acoustic measurements were performed with KAY-PENTAX CSL model 4500 and KAY-PENTAX EGG model 6103. During the measurements, the participants were asked to pronounce/ʌ/ phonation. Results: There was no significant difference between any MDVP parameters obtained from 4 BMI groups (p>0.05). Average-jitter, as one of the EGG frequency measurement parameter, has shown a significant difference (p=0.016), which was obtained from post-hoc datests of obese and normal group.According to the median value analysis, the difference was higher in obese individuals0.49 (0.27-1.03), than in normal individuals 0.37 (0.24-0.6). F0 values, obtained from MDVP and EGG, have no significant difference across any BMI group (p>0.05). Conclusion: When the EGG closure phases examined across BMI groups, it was founded that the obese group had higher glottal closing and closing phases compared to other BMI groups, while the glottal opening and opening phases were lower than the other BMI groups. In addition, the fact that the jitter value of the EGG-frequency measurements was higher in the obese group compared to the normal group. That suggests that the risk of dysphonia pathology may be higher in this group.
