Abstract
OBJECTIVES
This study used representative national survey data of Korean workers to estimate the occupational injury rate and to identify factors associated with occupational injuries.
METHODS
We analyzed data from the fourth Korea National Health and Nutrition Examination Survey conducted from 2007 to 2009 using the Complex Samples Frequencies procedure of the SPSS to estimate the occupational injury rate. Complex Samples Logistic Regression was performed to calculate a nationally representative odds ratios that reflects the likelihood of specific individual attributes and job characteristics being associated with occupational injuries. We did this while controlling for relevant covariates.
RESULTS
It was estimated that 3.5% of Korean workers have suffered at least one occupational injury and 1.9% of full-time employed workers have suffered occupational injuries which required more than 4 days of absence during the year. After adjustment for confounding variables, the experience of occupational injuries was related to several job characteristics, including exposure to hazards such as: air pollutants (OR=1.40; 95%CI: 1.05~1.85), noise (OR=1.31; 95%CI: 1.01~1.70), biological hazards (OR=1.60; 95%CI: 1.13~2.28), a difficult physical environment (OR=1.79; 95%CI: 1.33~2.41), and difficult ergonomic work (e.g. work involving awkward posture or heavy lifting) (OR=1.49; 95%CI: 1.11~2.00).
CONCLUSIONS
Using national survey data from the Korea National Health and Nutrition Examination Survey to estimate the occupational injury rate and to identify predictors of work-related injuries has several advantages. Futhermore, these results suggest that a hazardous work environment is associated with occupational injury.
