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

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.

The Relationships between Enterprise-scale Levels, Safety and Health Information Provisions in the Workplace, and the Consequential Attack Rate of Occupational Disease and Injuries / 대한산업의학회지

OBJECTIVES: We investigated the associations between enterprise-scale levels, the information supplied regarding workplace safety and health, and occupational injury and disease using a nationally representative sample of Korean workers. METHODS: We used data from the '2006 Working Condition Survey' performed by the Korean Occupational Safety & Health Agency. Demographic variables, employment characteristics, workplace hazards, enterprise-scale levels, information supplied regarding workplace safety and health, and occupational injury and disease were included for the study. RESULTS: Subjects who had high incomes, or who were male, full-time workers, or shift workers were more likely to provide safety and health information at work, compared to other workers' groups. The larger the enterprise-scale level, the more likely they would offer information on safety and health at work. Workers who worked in small companies, especially those with less than 10 employees, were the most likely respondents to provide safety and health information. In the corresponding logistic regression, the presence of occupational injuries and disease was significantly associated with the provision of health and safety information, the enterprise-scale level had little correlation. CONCLUSIONS: Our findings suggest that the provision of health and safety information is a critical factor regarding occupational injuries and disease. Proper safety and health education, even in small companies, may contribute to a decrease in occupational disease and injury.
