Influence of choral singing on the voice-related quality of life of public health service users

Abstract:

PURPOSE:

to investigate the voice-related quality of life of participants in a singing group organized by public health system professionals.

METHODS:

the study was conducted with 86 individuals of both genders, of which 46 were part of the control group, and 40 the study group, whose members participated in a singing group. Participants completed the questionnaire Voice-Related Quality of Life validated in Brazilian Portuguese. To verify the difference between the groups' averages we used the nonparametric Mann-Whitney test, with significance < 0.05.

RESULT:

the age averages of the groups were 58.95 years for the control group and 60.82 years for the study group, with no statistical difference between the averages. Both the total score and those related to each area separately, proved very similar among groups, and there was no significant difference found (p = 0.9295). In addition, it has been verified that the length of stay in the Encanto group did not influence the outcome of the scores.

CONCLUSION:

there was no significant difference between the scores of the groups, which may have been influenced by the fact that both have presented scores within the normal range. Similarly, the scores were not differentiated by length of stay in the Encanto group, which may be related to the antagonistic influence caused by the presbylarynx process, because of the predominantly elderly population. However, further studies are needed.
