Objective:
Hairdressers are more prone to respiratory diseases, bronchitis, asthma, shortness of breath, and cough due to the nature of their occupation and the constant use of cosmetics. Therefore, they may be prone to voice disorders or laryngeal problems. Voice problems may affect not only their social and emotional relationships but also their jobs. The current study was conducted to investigate voice problems and related risk factors in hairdressers.
Design:
Cross-sectional, descriptive-analytical.
Patients And Methods:
A total number of 293 women participated in the study. The study group consisted of 147 hairdressers and the control group consisted of 146 women with other jobs. All study participants were requested to complete a self-reported questionnaire. This questionnaire investigated demographic characteristics, voice problems and symptoms, laryngeal discomfort, working features, and workplace conditions. Chi-square, independent t-test, Fisher's exact test, and logistic regression were used to analyze the data.
Results:
The prevalence of voice problems in hairdressers and the control group was 33.33% and 15.75%, respectively, and this difference was statistically significant (P < 0.001). Results of the Chi-Square test showed that prevalence of hoarseness, vocal fatigue, dryness, and cough were higher in hairdressers than the control group (P < 0.05). According to regression logistic results, work time (hours per week) (P = 0.014; OR = 2.35; CI = 1.18-4.66) and presence of phonotraumatic behaviors (P = 0.012; OR = 2.73; CI = 1.24-5.96) increased the possibility of increasing the presence of voice symptoms among hairdressers.
Conclusion:
The findings revealed that self-reported voice problems were more prevalent in the hairdressers group than in the control group and therefore the hairdressers were more prone to an increased risk of developing voice problems. The most common symptoms in the hairdressers group were cough, hoarseness, and dryness in the vocal tract. Based on these results, in addition to paying attention to recommendations related to environmental issues and exposure to chemical hazards, hairdressers may benefit from receiving appropriate training in voice production, voice disorders, and the prevention of voice disorders.
