Frequency and Risk Factors of Voice Problems among Teachers

Abstract

Abstract Background Voice problems are thought to be one of the major occupational hazards of school teaching; as teachers often use their voice with high-intensity, in noisy classes, for a long time and without suitable breaks. The measurement of vocal demands and risk factors is essential for adjusting occupational safety and health services to this population’s needs. Aim of the Work To estimate the prevalence of voice problems and to identify the possible risk factors for developing voice pathology among primary school teachers. Materials and Methods A cross sectional study was carried out in 10 primary schools in Cairo, Egypt. A total of 225 primary school teachers were invited to participate in the study. Data were collected through an interview questionnaire addressing the prevalence of voice problems and potential risk factors. Descriptive analysis and chi-square test were used to measure the relationship between voice problems and associated risk factors. Results The frequency of voice problems among teachers was 56.4% at any point of time throughout their career. The teachers reporting voice problems were compared with those without problems. Gender was significantly associated with the development of voice problems among teachers. Conclusion A high frequency of self-reported voice problems was found among the studied teachers which indicates that school teaching is a high-risk profession for occurrence of voice problems.
