  • *The multivariable-adjusted prevalence of hearing impairment was calculated with adjustment for age, sex, body mass index (kg/m2), hypertension (yes or no), diabetes mellitus (yes or no), serum creatinine (sex-specific quintile) and current smoking status (yes or no) at baseline, as well as history of noisy work environment from 2008 to 2016 (yes or no).
