The number of workers who died due to occupational injury in Korea as of 2007 was 1,383. The aim of this study was to identify whether there were any differences in the risk of occupational injury between nonstandard workers (temporary workers and/or subcontract workers) and regular workers.
1,576 injured workers, selected from National Health Insurance and National Workers' Compensation Insurance, were interviewed via telephone survey using standardized questionnaires in 2007. The control group was 1,500 workers matched for age, gender, and severity of injury. A multivariate logistic regression model was used to analyze the association between the type of nonstandard work and occupational injury.
Nonstandard temporary workers were more likely to be injured than regular workers even if other related factors of occupational injury were statistically adjusted (adjusted odds ratio, OR 2.87, 95% confidence interval 2.37-3.49).
The reason why the risks of nonstandard workers are higher than those of regular workers is that nonstandard workers are placed in poor working conditions.
截至 2007 年，韩国因职业伤害而死亡的工人人数为 1383 人。本研究旨在确定非标准工人（临时工和/或分包工人）与正式工人之间职业伤害的风险是否存在差异。
2007 年，通过电话调查使用标准化问卷对从国家健康保险和国家工人赔偿保险中选择的 1576 名受伤工人进行了访谈。对照组是年龄、性别和受伤严重程度相匹配的 1500 名工人。使用多变量逻辑回归模型分析非标准工作类型与职业伤害之间的关联。
即使在统计调整了其他职业伤害相关因素后，非标准临时工受伤的可能性也高于正式工人（调整后的优势比，OR 2.87，95%置信区间 2.37-3.49）。
非标准工人的风险高于正式工人的原因是，非标准工人处于较差的工作条件下。
