Teachers experience a high prevalence of voice disorders due to extensive voice use. Risk factors include class size, teaching hours, dust, and tonsil issues, necessitating proactive voice care education.
Area of Science:
- Occupational Health
- Speech and Hearing Science
- Educational Psychology
Background:
- Teachers are a high-risk population for vocal dysfunction due to the demanding nature of their profession.
- Extensive voice use in teaching can lead to significant vocal strain and potential disorders.
- Understanding the prevalence and contributing factors is crucial for effective intervention.
Purpose of the Study:
- To determine the prevalence of voice disorders among teachers.
- To identify specific risk factors associated with voice strain in this occupational group.
- To inform the development of targeted voice care strategies for educators.
Main Methods:
- A cross-sectional study design was employed.
- The study was conducted among schoolteachers in Chitwan, Nepal.
- The Voice Handicap Index (VHI) questionnaire was utilized for data collection.
Main Results:
- A total of 315 teachers participated in the study, with a mean age of 36.7 years.
- Significant associations were found between voice handicap and factors such as public school employment, primary grade teaching, large class sizes (>50 pupils), extensive weekly teaching hours (>24 hours), classroom dust exposure, and a history of recurrent tonsil problems.
- These identified factors correlated with varying degrees of vocal handicap.
Conclusions:
- The study confirms a high prevalence of voice disorders among teachers.
- A comprehensive approach is recommended, emphasizing teacher education on voice care and management strategies that address identified risk factors.
- Implementing proactive measures can help mitigate vocal handicap and improve the vocal health of teachers.
