Occupational injury has been a serious social problem steadily. Sleep disturbance is a risk factor for occupational injury. However, there were few researches studied on the linking between sleep disturbance and occupational injury in general working population of Korea. Therefore, we explored the association between sleep disturbance and occupational injury among Korean workers.
This study used data from the 5th Korean Working Conditions Survey. Occupational injury was assessed by asking work related injury for 12 months prior to the point of the survey. Sleep disturbance was assessed using the Minimal Insomnia Symptoms Scale (MISS). To analyze the association between sleep disturbance and occupational injury, multiple logistic regression analysis was conducted.
The odds ratio (OR) of sleep disturbance group for occupational injury was 2.57 (95% confidence interval [CI]: 1.68-3.93) in the fully adjusted model. For the association between MISS score and occupational injury, it showed increasing trend that ORs increase from the 1st to the 4th quartiles. The OR of 2nd quartile was 1.10 (95% CI: 0.60-2.01), the OR of 3rd quartile was 2.27 (95% CI: 1.53-3.38) and the OR of 4th quartile was 2.80 (95% CI: 1.84-4.26).
Sleep disturbance was associated with occupational injury. In addition, increasing trend was observed between MISS score and occupational injury. These findings imply that developing of intervention programs to manage sleep disturbance and fatigue may be necessary to prevent occupational injury.
职业伤害一直是一个严重的社会问题。睡眠障碍是职业伤害的一个风险因素。然而，在韩国普通工作人群中，关于睡眠障碍与职业伤害之间联系的研究很少。因此，我们探讨了韩国工人中睡眠障碍与职业伤害之间的关联。
本研究使用了第五次韩国工作条件调查的数据。通过询问调查前12个月内与工作相关的伤害来评估职业伤害。使用最小失眠症状量表（MISS）评估睡眠障碍。为了分析睡眠障碍与职业伤害之间的关联，进行了多因素逻辑回归分析。
在完全调整模型中，睡眠障碍组发生职业伤害的优势比（OR）为2.57（95%置信区间[CI]：1.68 - 3.93）。对于MISS评分与职业伤害之间的关联，从第一四分位数到第四四分位数，OR呈上升趋势。第二四分位数的OR为1.10（95%CI：0.60 - 2.01），第三四分位数的OR为2.27（95%CI：1.53 - 3.38），第四四分位数的OR为2.80（95%CI：1.84 - 4.26）。
睡眠障碍与职业伤害有关。此外，在MISS评分与职业伤害之间观察到上升趋势。这些发现意味着可能有必要制定干预计划来管理睡眠障碍和疲劳，以预防职业伤害。
