“…Cortisol is released during stress and previous studies suggest that stress is a risk factor in developing vocal symptoms or dysphonia (Baker, 2008;Dietrich, Verdolini Abbott, GartnerSchmitdt & Rosen, 2008;Dietrich & Verdolini Abbott, 2012;Chen, Chiang, Chung, Hsiao & Hsiao, 2010;Gassull, Casanova, Botey, Amador, 2010;Lyberg Åhlander, 2011;Lyberg Åhlander, Pelegrín García, Whitling, Rydell & Löfqvist, 2014;Rantala, Hakala, Holmqvist & Sala, 2012). About 23-25% of individuals seeking care for voice disorders or with common vocal pathologies show stress scores deviating upwards from normal scores Misono et al, 2014).…”

Purpose: We investigated whether participants who reported more often occurring vocal symptoms showed higher salivary cortisol levels and if such possible associations were different for men and women. Method:The participants (N = 170; men n = 49, women n = 121) consisted of a populationbased sample of Finnish twins born between 1961 and 1989. The participants submitted saliva samples for hormone analysis and completed a web-questionnaire including questions regarding the occurrence of six vocal symptoms during the past 12 months. The data were analyzed using the Generalized Estimated Equations (GEE) method.Results: A composite variable of the vocal symptoms showed a significant positive association with salivary cortisol levels (p < .001). Three of the six vocal symptoms were significantly associated with the level of cortisol when analyzed separately (p-values below .05). The results showed no gender difference regarding the effect of salivary cortisol on vocal symptoms. Conclusions:There was a positive association between the occurrence of vocal symptoms and salivary cortisol levels. Participants with higher cortisol levels reported more often occurring vocal symptoms. This could have a connection to the influence of stress on vocal symptoms since stress is a known risk factor of vocal symptoms and salivary cortisol can be seen as a biomarker for stress.

“…So far, we have found that the risk factors and voice symptoms correlate with each other [2]. The VEAW divides voice ergonomic factors into four groups: working culture, working postures, indoor air quality, and noise.…”

“…Poor postural alignment impairs voice production [8,9] and increases the incidence of voice symptoms [2,8,10]. Patients with voice disorders have been found to use postures such as posterior weight bearing of the body and forward head thrust [8].…”

Objective: The aim of the study was to investigate if voice ergonomic risk factors in classrooms correlated with acoustic parameters of teachers’ voice production. Methods: The voice ergonomic risk factors in the fields of working culture, working postures and indoor air quality were assessed in 40 classrooms using the Voice Ergonomic Assessment in Work Environment – Handbook and Checklist. Teachers (32 females, 8 males) from the above-mentioned classrooms recorded text readings before and after a working day. Fundamental frequency, sound pressure level (SPL) and the slope of the spectrum (alpha ratio) were analyzed. Results: The higher the number of the risk factors in the classrooms, the higher SPL the teachers used and the more strained the males’ voices (increased alpha ratio) were. The SPL was already higher before the working day in the teachers with higher risk than in those with lower risk. Conclusion: In the working environment with many voice ergonomic risk factors, speakers increase voice loudness and use more strained voice quality (males). A practical implication of the results is that voice ergonomic assessments are needed in schools.

“…Cortisol is involved in a feedback system in the stress response, including a stress-induced activation of the corticotropin releasing factor (CRF) in the paraventricular nucleus of the hypothalamus resulting in a release of adrenocorticotropic hormone (ACTH) from the pituitary, and an ACTH induced release of cortisol from the adrenal cortex (Hellhammer et al, 2009). Psychological stressors increase cortisol levels and previous studies show that stress should be regarded as a risk factor in developing vocal symptoms or dysphonia (Baker, 2008;Chen, Chiang, Chung, Hsiao & Hsiao, 2010;Dietrich et al, 2008;Dietrich & Verdolini Abbott, 2012;Gassull et al, 2010;Rantala et al, 2012). In a study by Holmqvist, Johansson, Santtila, Westberg, von der Pahlen and Simberg (submitted) the results showed a positive association between the occurrence of vocal symptoms and the level of salivary cortisol.…”

“…Stress has been indicated as a risk factor for vocal symptoms (Dietrich, Verdolini Abott, Gartner-Schmidt & Rosen, 2008;Giddens, Barron, Byrd-Craven, Clark & Winter, 2013;Rantala, Hakala, Holmqvist & Sala, 2012). Variations in fundamental frequency as well as acoustical vocal changes have been reported as vocal symptoms of acute stress (for a review see Giddens et al, 2013).…”

Purpose: Oxytocin and arginine vasopressin are associated with different aspects of the stress response. As stress is regarded a risk factor for vocal symptoms, we wanted to explore the association between the oxytocin receptor gene (OXTR) and arginine vasopressin 1A receptor gene (AVPR1A) single nucleotide polymorphisms (SNP) and vocal symptoms. We also wanted to explore whether such effects might be mediated by cortisol since oxytocin and vasopressin associated with cortisol levels.Method: A population based sample (N = 657) of Finnish twins (born 1961-1989) completed a web-questionnaire on the occurrence of vocal symptoms. A total of (n = 170) participants submitted saliva samples for hormone analysis. A total of 20 OXTR and AVPR1A SNPs were analyzed.Results: Three OXTR polymorphisms (rs2270465, rs2268493, rs7632287) and two AVPR1A polymorphisms (rs1587097, rs1042615) showed nominal effects (p < .05) on vocal symptoms, of which one (rs1587097) remained significant after correcting for multiple testing (p = .003). We found potential mediation of the effect of the OXTR rs2268493 polymorphism on vocal symptoms through levels of cortisol.Conclusions: The associations between variants of OXTR and AVPR1A and vocal symptoms indicate that oxytocin and vasopressin might influence vocal symptoms. The effect of oxytocin seems to be partly mediated through cortisol actions.
