Voice disorders are a significant occupational hazard for teachers, as highlighted in the research article titled "The prevalence and risk factors for perceived voice disorders in public school teachers" by Feng et al. This study, conducted in the Jimei district of Xiamen, China, offers critical insights into the prevalence and risk factors associated with perceived voice disorders (PVD) among public school teachers. Understanding these factors is crucial for practitioners focused on improving outcomes for teachers through preventive and therapeutic measures.
The study surveyed 3,140 public kindergarten and elementary school teachers, classifying them into two groups: those with perceived voice disorders (PVD) and those without (NPVD), based on the Voice Handicap Index. The findings revealed a PVD prevalence rate of 47.52%, indicating that nearly half of the teachers experienced some form of voice disorder.
Key Risk Factors Identified
The study identified several significant risk factors associated with PVD:
- Gender: Female teachers were found to have a higher risk (OR = 1.574).
- Technical Title: Teachers with a middle-rank technical title or higher had an increased risk (OR = 2.199).
- Continuous Lecturing: Teachers who lectured continuously for more than three classes had a notably higher risk (OR = 3.034).
- Weekly Teaching Load: Those who taught more than ten classes per week were also at greater risk (OR = 1.436).
- Subject Taught: Teachers of art or physical education had an elevated risk (OR = 1.742).
Implications for Practice
These findings underscore the importance of implementing preventive voice care programs tailored specifically for teachers. Here are some actionable steps practitioners can take based on the study's outcomes:
- Voice Care Programs: Develop and promote voice care programs within schools, emphasizing vocal hygiene and preventive measures.
- Timetable Management: Advocate for reasonable timetable arrangements to prevent continuous lecturing for extended periods.
- Workload Distribution: Encourage the recruitment of additional teachers to distribute the teaching load more evenly, reducing the number of classes each teacher handles weekly.
- Specialized Training: Provide specialized training for teachers, particularly those in high-risk categories like art and physical education, on voice preservation techniques.
- Regular Screenings: Implement regular voice screenings for early detection and intervention of voice disorders.
Encouraging Further Research
While this study provides valuable insights, it also highlights the need for further research in this area. Practitioners are encouraged to engage in or support additional studies to explore:
- The long-term effectiveness of preventive voice care programs.
- The impact of environmental factors, such as classroom acoustics, on voice health.
- The role of psychological stress in the development of voice disorders among teachers.
By integrating the findings from this study into practice and encouraging further research, practitioners can play a pivotal role in reducing the prevalence of voice disorders among teachers and improving their overall well-being.
