Risk of development of professional pathology of the voice apparatus in teachers of secondary schools.

Abstract

The frequency of functional voice disorders associated with profession varies from 13,7% to 70%, which requires the timely identification of the risk of developing professional laryngitis, development and implementation of modern effective risk management models. Aim - to determine the risk of developing professional pathology of the vocal apparatus in teachers of general education schools. The analysis of age and seniority is performed among 5346 teachers. Risk determination of development of professional laryngitis is carried out according to standard methodology by analyzing outpatient cards of 63 teachers. The probability of getting sick with the work experience of up to 5 years is 5% of the number of patients, and with the work experience of 35 years or more is 100%. The probability of getting sick with professional laryngitis is by 95% due to voice load and only by 5% to other factors. The absolute risk of developing professional laryngitis is the highest in the age group of 51-54 (AR=0,21) years and 55-60 years (AR=0.22). The relative risk of developing professional laryngitis with 20-24 years of work experience is 20 with etiological proportion of voice load of 95 %, but with increasing length of service, the relative risk, like etiological proportion of the relative risk, is less than the age-related changes.
