Predictors of Hearing Protection Behavior Among Power Plant Workers

ABSTRACT

PURPOSE: This study aimed to identify factors affecting the use of the hearing protection devices (HPDs) among workers exposed to noise using the Pender Health Promotion Model. METHODS: The 222 subjects came from thermal power plants with similar noise levels, which are between 80 dB and 90 dB in South Korea. Data were collected with self-administered questionnaires designed to measure concepts from the Health Promotion Model. RESULTS: Mean percent times of using the HPDs at their most recent job site were 50.9%, and 20.3% had never the HPDs. The predictors of HPD use were social modeling (OR = 1.380), perceived benefits (OR = 1.150), and working at noisy worksites (OR = 4.925) when the outcome was based on the "non-use" versus "used at least once". However, the predictors of HPD use were social modeling (OR = 1.795) and perceived benefits (OR = 1.139) based on the "less than half-of-the-time-use" versus "more than half-of-the-time-use". CONCLUSION: Social modeling and perceived benefits of using the HPDs are important for workers to keep minimal or certain level of using the HPDs.
