RESUMO

Obesity is an endemic illness whose estimated prevalence, from 1989 to 1994, was 40% amongst North American people and 20% amongst Brazilian people. It is a disease that causes several health problems on a biopsychosocial basis. Amongst these consequences of obesity, the voice characteristics of affected people is a target of discussion and analysis. The purpose of this study was to set the voice patterns of people affected by morbid obesity, by making a comparison to the voice patterns of people who are not fat. The comparison was made through the acoustic and auditory-perceptive analysis in order to establish the voice patterns. Method: We have selected 45 adults who are volunteers coming from the Center for Obesity Specialized in the Digestive System Surgery. The selected people were men and women whose Body Mass Index (BMI) is higher than 35 kg/ m2. For each person selected, there is another one, also adult, same sex, age and smoking habit, but with a BMI under than 30 kg/ m2. All the volunteers made laryngology test and their voice was recorded in the Phonoaudiology Department, from the Center of Otorhinolaryngology. We prepared the statistics, disregarding the values under 0.05, considered statistically insignificant. The results showed that the patients affected by morbid obesity presented more frequently: signs on their larynx that indicate gastroesophageal reflux (GER); 4 (four) times more hoarseness, 3 (three) times more instability, 5 (five) times more vocal fatigue and breathing; 5 (five) times more voice cracking. Besides these disabilities, people affected by morbid obesity presented changes in Jitter, Shimmer and Noise, as well as low Maximum Phonation Time (MPT). We conclude that people affected by morbid obesity present roughness, breathness with phonatory instability, changes in Jitter and Shimmer, low MPT and cracking voice
