Increasing Prevalence of Voice Disorders in the USA: Updates in the COVID Era

OBJECTIVE

To estimate the current prevalence of voice disorders among adults in the United States; to determine the association of individual factors with voice disorders.

METHODS

The 2022 National Health Interview Survey (NHIS) was analyzed to identify adults reporting voice problems in the past 12 months. Demographics were assessed, as well as the duration, severity, and resolution of the voice problem. The relationship between voice problems, gender, lost workdays, and long COVID was investigated. A comparison to the 2012 NHIS was made to determine changes in voice disorder prevalence.

RESULTS

29.9 million Americans (95%CI[28.3-31.5]) annually report a voice problem, representing 12.2% of the population (95%CI[11.7-12.8%]). Overall, 26.8% and 13.2% reported the severity of their voice problem as moderate or severe, respectively. Only 5.1% (95%CI[4.3-6.0%]) of respondents sought treatment. Most voice problems were resolved within 1 week (53.0%,95%CI[50.9-55.1%]). Females were more likely than males to report a voice problem (14.4% vs. 10.0%,95%CI[13.7-15.1] and [9.3-10.7], respectively). The 17.6 million Americans with long COVID symptoms were more likely to have voice complaints than those without (21.1% vs. 11.6%,95%CI[18.9-23.5%] and [11.1-12.1%], respectively). Lost workdays were not significantly higher for those with voice disorders compared to those without (17.1 vs. 12.9 days,95%CI[12.0-22.1] and [11.0-14.8], respectively).

CONCLUSIONS

Voice problems affect approximately 1 in 8 adults in the U.S. annually, demonstrating an alarming increased prevalence since 2012 using the same survey methodology. Relatively few individuals seek care for their voice problem, despite significant self-reported impact. Further study is required regarding the impact of COVID and changes in voice use patterns on voice disorders.

Voice handicap and voice-related quality of life in COVID-19 patients

OBJECTIVES

Identifying voice handicap and voice-related quality of life in patients presenting pulmonary impairment associated with COVID-19 infection, comparing pulmonary parameters between these patients and individuals in the control group, as well as correlating pulmonary parameters to self-assessment questionnaires (IDV-10 and QVV).

METHODS

Thirty-five (35) patients presenting pulmonary impairment with COVID-19 infection were herein selected and compared to 35 individuals who were not affected by COVID-19 infection. Two self-assessment questionnaires were applied (vocal handicap index and voice quality of life protocol). Maximum phonation time Forced Expiratory Pressure (PEF) and Forced Inspiratory Pressure (PIF) were measured and videolaryngoscopy was performed.

RESULTS

There was statistically significant difference in scores recorded in voice self-assessment questionnaires (IDV-10 and QVV), Expiratory Pressure (PEF) and Forced Inspiratory Pressure (PIF) between patients with pulmonary impairment associated with COVID-19 infection and those in the control group. Correlation between PEF/PIF and scores recorded in voice self-assessment questionnaires was also observed.

CONCLUSION

Pulmonary impairment associated with COVID-19 infection has worsened voice handicap and voice-related quality of life in the assessed patients, as well as reduced their forced expiratory and inspiratory pressure in comparison to the control group.

Effects of an 8-Week Mindfulness Course in People With Voice Disorders

OBJECTIVES

Nearly every modern textbook on the etiology and treatment of voice disorders (VD) recommends stress reduction for VD patients. The benefits of mindfulness for stress reduction are well documented, but published literature on mindfulness and VD is sparse. Our objective was to determine whether an 8-week mindfulness course could increase mindfulness and lower stress in people with VD, leading to a decrease in vocal handicap.

STUDY DESIGN

Mixed methods study.

METHODS

Participants: 69 individuals with VD: 39 were mindfulness course participants (MCP), 30 were in a waitlist control group (WCG). Exclusionary criteria: patients in voice therapy. Before and after the 8-week timeframe, participants took the Mindful Attention and Awareness Scale (MAAS), Perceived Stress Scale-10 (PSS-10), Voice Handicap Index (VHI), and-for singers (n = 36)-the Singing Voice Handicap Index (SVHI). Follow-up interviews were conducted with select participants.

RESULTS

In the MCP, each of the outcomes significantly changed in the direction hypothesized, resulting in increased MAAS (P = 0.000) and decreased PSS-10 (P = 0.007), VHI (P = 0.000), and SVHI (P = 0.021, n = 22) scores. Using a 2 × 2 Repeated Measures ANOVA, two outcomes were statistically different for the MCP from pre to postcourse-MAAS increased (P = 0.006, ES = 0.107) and VHI decreased (P = 0.034, ES = 0.065)-in comparison to no change in the WCG. Follow-up interviews revealed increased acceptance of the VD; reduced stress, physical tension, and pain/discomfort; increased somatic (or interoceptive) awareness; community with other VD patients; and positive speaking and singing voice changes.

CONCLUSIONS

An 8-week mindfulness course shows promise for reducing stress in people with VD, lowering voice handicap, and improving quality of life. Future research should evaluate mindfulness in patients with specific voice disorders; patients with higher and lower VHI scores; singers; and patients who experience throat pain. Mindfulness should also be evaluated within a standard voice therapy protocol.
