A possible association between dysphonia and sleep duration: A cross-sectional study based on the Korean National Health and nutrition examination surveys from 2010 to 2012

Abstract

BackgroundSleep is important in terms of good general health and appropriate sleep duration has been linked to quality-of-life. Dysphonia may impair communication and social relationships, and is thus also closely related to quality-of-life. No large-scale, cross-sectional epidemiological study of a sample representative of the population of an entire country has yet assessed the possible existence of a relationship between sleep duration and dysphonia.MethodsWe investigated a possible association between subjective voice problems and self-reported sleep duration in South Korean subjects using 2010–2012 data from the Korean National Health and Nutrition Examination Survey (KNHANES). Cross-sectional data on 17,806 adults (7,578 males and 10,228 females) over the age of 19 years who completed the KNHANES were analyzed. All participants reported voice problems (if present) and their daily average sleep duration using a self-reporting questionnaire. Sleep duration was classified into five categories as follows: ≤5, 6, 7, 8, and ≥9 h/day.ResultsThe overall prevalence of dysphonia was 6.8%; 5.7% in males and 7.7% in females. The prevalence for dysphonia by sleep duration exhibited a U-shape, with the lowest point being at sleep duration of 7-8h. After adjustment for covariates (age, sex, smoking status, alcohol consumption, regular exercise, low income, high-level education), a sleep duration of ≤5 h (OR = 1.454; 95% CI, 1.153–1.832) and a sleep duration of ≥9 h (OR = 1.365; 95% CI, 1.017–1.832) were significantly associated with dysphonia, compared to a sleep duration of 7 h. In terms of gender, males who slept for ≥9 h were at a 2-fold (OR = 2.028; 95% CI, 1.22–3.35) higher odds for dysphonia (p<0.05) compared to those who slept for 7 h. A sleep duration ≤5 h was associated with a 1.6-fold (OR = 1.574; 95% CI, 1.203–2.247) higher odds of dysphonia ≥3 weeks in duration (long-term dysphonia).ConclusionsThis is the first study to show that both short and long sleep duration were significantly associated with the development of dysphonia. The association between sleep duration and dysphonia was more marked in males than females. A sleep duration ≤5 h had a significant impact on the prevalence of long-term dysphonia.

Effect of teacher’s working conditions on voice disorder in Korea: a nationwide survey

“…One Korean study using 2010–2012 data from the Korean National Health and Nutrition Examination Survey(KNHANES) revealed that 5 sleep hours or less was significantly associated with self-reported dysphonia and long-term dysphonia compared to 7 sleep hours: aOR = 1.45 (1.15–1.83), ≥ 3 weeks aOR = 1.57 (1.20–2.25), respectively [ 42 ]. Another study of teachers showed that there was a significant association between hoarseness and less than 6 sleep hours after adjustment for teaching career [ 43 ].…”

Dysphonia in Smokers of Combustible Cigarettes and E-cigarettes Measured Using the Filipino Voice Handicap Index

“…15,12 In South Korea, Cho reported a prevalence of 6.7%. 16 The prevalence of impairment in our sample using a cut-off of total VHI of 18 was 17.31% (8.23-30.32%). Cho's study 16 was a nationwide cross-sectional survey that was representative of the Korean population as it employed a more complex, stratified, multistage probability sampling design.…”

Benninger's study 12 employed a large administrative database from which nationwide estimates were projected.…”

“…Our current study on the other hand, only employed convenience and snowball sampling within Metro Manila. Also, for the Korean study, 16 the presence of dysphonia was self-reported instead of based on a Voice Handicap Index. Cultural differences in the perception of dysphonia or impairment cannot be disregarded.…”

“…A estes somam-se os fatores ambientais, socioculturais, históricos, organizacionais, administrativos, sobrecarga de trabalho e relacionamento interpessoal.Como se pode observar, há uma complexa relação entre os fatores intrínsecos e extrínsecos para o desenvolvimento da disfonia. É possível que o envolvimento do professor com suas atividades laborativas, dentro e fora do ambiente de trabalho, assim como jornadas de trabalho exaustivas, já que essa categoria pode desenvolver até 60 horas semanais, contribua para o seu baixo envolvimento com atividade física.A atividade física pode trazer benefícios para a saúde vocal, pois de acordo com Sataloff (1997) apud Steffani, Vieceli e Grasel(2011, p.1) a adequada capacidade respiratória está associada à maior eficiência de voz e assim, no caso de indivíduos que utilizam a voz como instrumento de trabalho, devido ao decréscimo normal da função respiratória com a idade, torna-se essencial um melhor condicionamento não apenas respiratório, mas também físico e da musculatura abdominal" SATALOFF (1997) apud STEFFANI, VIECELI e GRASEL(2011, p.1).Entretanto, os achados deste estudo não demonstraram diferença estatisticamente significativa entre os níveis de atividade física e a disfonia (p=0,798) Cho et al (2017),. avaliando uma amostra nacionalmente representativa de 17.806 adultos com o objetivo de investigar uma possível relação entre disfonia, duração do sono e covariáveis como a prática de atividade física regular, também não encontraram associação significativa (p=0,925); vale ressaltar que este estudo não avaliou exclusivamente professores.praticantes de atividade física podem ter menores níveis de estresse e tensão corporal e, consequentemente, vocal, o que sugere uma relação entre sedentarismo e disfonia.…”
