“…There was a statistically significant difference in MPT values for the vowels [a], [i], and [u] before and after bariatric surgery (Table 1), which corroborates with the findings of other authors [7][8][9]15] who found a reduction in this parameter in individuals with obesity. This result can be explained by the presence of fat in the neck in obese individuals, which predisposes the increase in type II muscle fibers in the dilator muscles of the upper airways, causing lower respiratory muscle strength [17] and difficulty in mobilizing the airflow to the same degree as in non-obese individuals. This configuration may explain the imbalance between the myoelastic and aerodynamic forces of the larynx and result in reduced MPT [18].…”

“…Studies have shown that the measurement of NC can be used to define obesity and that excess fat and muscle can overwhelm the respiratory system [17]. It is worthy of note that the accumulation of fat in the neck may cause stress on the extrinsic muscles of the larynx, which are secondarily responsible for voice frequency [16], by restricting the extent of laryngeal movement and consequently reduce this parameter.…”

“…The circumferences were measured in centimeters using a non-elastic tape measure. Neck circumference was measured at the cricoid cartilage 16 ; waist circumference was measured at the midpoint between the margin of the last rib and the upper margin of the iliac crest; hip circumference was measured at the greater trochanter of femur 17 ; and with the measures of waist circumference and hip circumference, the waist/hip ratio was obtained.…”

BACKGROUND:The objective of the present study was to develop predictive equations for maximum respiratory pressures in women according to anthropometric characteristics. METHODS: This cross-sectional study included 156 women between ages 25 and 65 y with a body mass index (BMI) between 18.5 and 55 kg/m 2 , who were evaluated for body mass, height, BMI, neck circumference, waist circumference, hip circumference, and waist/hip ratio. Respiratory muscle strength was assessed by measuring the maximum inspiratory pressure (P Imax ) and maximum expiratory pressure (P Emax ) with an analog vacuum manometer. For statistical analysis, the KolmogorovSmirnov test, Spearman correlation test, and stepwise multiple regression were used. The level of statistical significance was set at 5% (P < .05). RESULTS: Body mass, BMI, neck circumference, waist circumference, hip circumference, and waist/hip ratio showed significant and positive correlations with P Imax and P Emax . On the other hand, age and height showed no significant correlations with P Imax and P Emax . In the regression analysis, the variables that correlated significantly with P Imax and P Emax were used. CONCLUSIONS: Body mass was the variable that best contributed to predicting maximum respiratory pressures values in women (11.70% of the variations of the P Imax and 21.05% of the variations of the P Emax ). For P Imax measurements, the equation ؊0.2 ؋ body mass ؊ 65.6 was established, and for P Emax , the equation 0.3 ؋ body mass ؉ 66.4 was used. It is suggested that the predictive equations developed in this study can be used in the interpretation of the assessment of respiratory muscle strength in morbidly obese women 25-65 y of age.

“…The correlation between body shape and fundamental frequency seems plausible in some cases, considering the larynx is the hormonal target 4 ,56, 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 . However, studies show that weight and body shape of male and female adults are negatively correlated with fundamental frequency 7 .…”

BackgroundObese people have abnormal deposition of fat in the vocal tract that can interfere with the acoustic voice.AimTo relate the fundamental frequency, the maximum phonation time and voice complaints from a group of morbidly obese women.MethodsObservational, 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.ResultsThe 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.ConclusionIncreased adipose tissue in the vocal tract interfered in the vocal parameters.

Abstract: Although adiposity patterns did not affect inspiratory muscle strength, neck adiposity was associated lower respiratory muscle endurance.
