SOUZA, Lourdes Bernadete Rocha de; PEREIRA, Rayane Medeiros; SANTOS, Marquiony Marques dos  y  GODOY, Cynthia Meida de Almeida. Frequência fundamental, tempo máximo de fonação e queixas vocais em mulheres com obesidade mórbidaFundamental frequency, phonation maximum time and vocal complaints in morbidly obese women. ABCD, arq. bras. cir. dig. [online]. 2014, vol.27, n.1, pp.43-46. ISSN 0102-6720.


: Obese people have abnormal deposition of fat in the vocal tract that can interfere with the acoustic voice.


: To relate the fundamental frequency, the maximum phonation time and voice complaints from a group of morbidly obese women.


: Observational, cross-sectional and descriptive study that included 44 morbidly obese women, mean age of 42.45 (±10.31) years old, observational group and 30 women without obesity, control group, with 33.79 (±4.51)years old. The voice recording was done in a quiet environment, on a laptop using the program ANAGRAF acoustic analysis of speech sounds. To extract the values ​​of fundamental frequency the subjects were asked to produce vowel [a] at usual intensity for a period in average of three seconds. After the voice recording, participants were prompted to produce sustained vowel [ a] , [ i] and [ u] at usual intensity and height, using a stopwatch to measure the time that each participant could hold each vowel.


: The majority, 31(70.5%), had vocal complaints, with a higher percentage for complaints of vocal fatigue 20(64.51%) and voice failures 19(61.29%) followed by dryness of the throat in 15 (48.38%) and effort to speak 13(41.93%). There was no statistically significant difference regarding the mean fundamental frequency of the voice in both groups, but there was significance between the two groups regarding maximum phonation.


: Increased adipose tissue in the vocal tract interfered in the vocal parameters.
