Dermatoglyphy and vocal condition of professors

ABSTRACT

Purpose

To investigate the association between the dermatoglyphic profile and the vocal condition of teachers at a public higher education institution.

Methods

49 professors participated in the study. After signing the Informed Consent Form, the following instruments were used: sociodemographic questionnaire and Voice Disorder Screening Index (ITDV). Fingerprints were collected using the Integrated Biometric Watson Mini scanner and analysis performed using the Cummins and Midlo protocol. The results were presented in absolute frequency. The Chi-Square Test was performed, with a significance level of 5%, to verify the association of ITDV vocal symptoms with a dermatoglyphic profile. This study was approved by the Research Ethics Committee of a public higher education institution under protocol number 3,372.226.

Results

There was a prevalence of females among the university professors studied. As for the classification of the dermatoglyphic profile , most had an anaerobic profile. There was a statistically significant association only between dermatoglyphic profile and weekly workload.

Conclusion

Most subjects with an anaerobic profile had more frequency of vocal symptoms. There was a statistically significant association between weekly working hours and dermatoglyphic profile.
