Somatotype and Body Composition of Normal and Dysphonic Adult Speakers


, : Somatotype and Body Composition of Normal and Dysphonic Adult Speakers. Journal of Voice

Voice quality provides information about the anatomical characteristics of the speaker. The patterns of somatotype and body composition can provide essential knowledge to characterize the individuality of voice quality. The aim of this study was to verify if there were significant differences in somatotype and body composition between normal and dysphonic speakers. Cross-sectional study. Anthropometric measurements were taken of a sample of 72 adult participants (40 normal speakers and 32 dysphonic speakers) according to International Society for the Advancement of Kinanthropometry standards, which allowed the calculation of endomorphism, mesomorphism, ectomorphism components, body density, body mass index, fat mass, percentage fat, and fat-free mass. Perception and acoustic evaluations as well as nasoendoscopy were used to assign speakers into normal or dysphonic groups. There were no significant differences between normal and dysphonic speakers in the mean somatotype attitudinal distance and somatotype dispersion distance (in spite of marginally significant differences [P < 0.10] in somatotype attitudinal distance and somatotype dispersion distance between groups) and in the mean vector of the somatotype components. Furthermore, no significant differences were found between groups concerning the mean of percentage fat, fat mass, fat-free mass, body density, and body mass index after controlling by sex. The findings suggested no significant differences in the somatotype and body composition variables, between normal and dysphonic speakers.

Dual A-kinase anchoring protein 1a (D-AKAP1a, AKAP1) regulates cAMP signaling in mitochondria. However, it is not clear how D-AKAP1a is associated with mitochondria. In this study, we show that D-AKAP1a is a transmembrane protein in the mitochondr...

The evaluation of juxtaorbital anomalies with routine imaging, including CT and MR imaging, usually is insufficient for endovascular therapy planning. Cerebral angiography remains crucial to define detail necessary for endovascular therapy. This a...
