Relationship between occupational injuries and the provision of safety and health information: Data from the 4th Korean working conditions survey

Abstract

Background: The aim of this study was to examine the relationship between the provision of safety and health information (PSHI) and occupational injuries. Methods: This study was based on data from the 4th Korean Working Conditions Survey (KWCS) (2014). The sample consisted of data from 24,527 wage workers and was divided into high-risk and low-risk groups, depending on the probability of occupational injury. The high-risk group included subjects who could cause harm to themselves or others due to errors during work. We applied chi-squared tests and logistic regression analyses to examine the relationship between PSHI and occupational injuries. Results: In the high-risk group, workers with no PSHI showed an adjusted odds ratio of 1.81 for occupational injury (95% CI 1.33-2.47). In contrast, there was no statistically significant relationship between PSHI and the incidence of occupational injury in the low-risk group. Conclusions: To prevent occupational injuries, multi-faceted approaches that take different levels of injury risk into account are needed. Among workers with a high risk of occupational injury, more a stringent safety education program is required.
