The main objective of this study was to assess the prevalence of lower back pain (LBP) and clarify the effect of work-related psychological factors on LBP. Nationwide survey data collected from male Korean firefighters (FIFS) were used. To identify the risk factors (work-related psychological factors such as job stress and depression) affecting LBP, the χ test and multivariate logistic regression analyses were conducted. The prevalence of LBP was 19.3% and was highest in the emergency medical service (31.8%) part of FF job types. Within job stress, an uncomfortable physical environment, high mental job demand and organizational injustice were associated with LBP. However, inadequate social support inversely associated with LBP. Depression and high-risk alcohol drinking were related to LBP. LBP was closely related to job stress, depression and alcohol intake. Proper interventions of psychological factors should therefore be addressed to control LBP in FIFS.
BackgroundThe aim of this study was to examine the relationship between the provision of safety and health information (PSHI) and occupational injuries.MethodsThis 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.ResultsIn 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.ConclusionsTo 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
