Objective:
To characterise the burden of voice disorders in teachers in a UK population, compare it with non-teachers and identify groups of teachers who may be particularly at risk of developing a voice problem.
Design:
Questionnaire-based survey of primary and secondary school teachers and non-teachers. Questions consisted of general demographics, VHI-10 and questions relating to voice problems.
Methods:
Distribution of questionnaires to teachers and non-teachers and statistical analysis of the responses.
Setting:
University teaching hospital.
Participants:
Teachers and non-teachers in a region of North West England.
Main Outcome Measures:
Identification of risk factors for voice problems in teachers, compared to non-teachers.
Results:
A total of 210 primary and 244 secondary school teachers and 304 non-teachers participated in the questionnaire survey. Response rates were 67.9% from primary schools, 41.2% from secondary schools and 40.0% from the non-teachers. 30.0% of teachers and 9.0% of non-teachers had reported problems with their voice. 12.8% of teachers and 2.0% of non-teachers had missed work due to voice problems. 14.1% of teachers and 5.3% non-teachers had seen a general practitioner for voice-related problems, whilst 7.1% of teachers and 6.3% of non-teachers had been referred to an otolaryngologist or speech therapist for voice problems. Factors related to VHI-10 (P < .05) were identified.
Conclusions:
Voice disorders are an occupational health problem for teachers, with a significant burden of these disorders in this group of teachers in the UK. We have identified risk factors that could be exploited to identify groups of teachers who would benefit from early intervention.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
