Background and aims
Noise-Induced Hearing Loss (NIHL) is an important occupational disorder. High percentage of workers in occupational environments did not use the hearing protection device against harmful noise. This study was carried out to study factors related to workers' use of Hearing protection Device in Knitting & spinning factories of Yazd city based on protection motivation theory.
Methods
In this cross-sectional analytical study 280 workers of the knitting & spinning factories of Yazd City who exposed to harmful noise (over 85dB) selected among the three factories by cluster sampling. The data gathered via exclusive interviews with selected workers using the questionnaire designed based on protection motivation theory and were analyzed
Results
42/5 percent of workers permanently used hearing protection devices, and 20/7 percent of workers never use.There was a significant correlation between the age of workers and the mean score components of PMT perceived severity, perceived vulnerability, perceived response efficacy and protection motivation. There was also a significant correlation between the work experience and the mean score of PMT factors perceived severity, perceived response efficacy and perceived vulnerability. Also there was a significant correlation between workers' education level and the mean score of perceived response efficacy and there was a significant correlation between protection motivation and the mean score components of PMT perceived vulnerability, perceived self-efficacy, perceived response efficacy, perceived costs and behavior
Conclusion
Regarding the significant correlations between the more constructs of PMT and protection motivation of workers for using hearing protective device, designing educational program based on PMT to increase hearing protection devices usage among workers is recommended.
