The association between lifetime cigarette smoking and dysphonia in the Korean general population: findings from a national survey.

Cigarette smoking may increase the risk of dysphonia.

​This study was carried out to clarify the association between long-term smoking and the odds of experiencing dysphonia. Researchers assessed data on the smoking habits and prevalence of dysphonia in a study population comprising of more than 3,600 Korean men and women above the age of 19. 

Researchers found out that a lifetime of smoking put an individual at great risk of suffering from dysphonia. According to this study, current smokers demonstrated 1.8 and 1.6 times higher risk of coming down with voice problems and laryngeal disorders respectively than non-smokers. The findings of this study show that cigarette smoking may contribute significantly to the development of dysphonia.
