摘　　要：目的探讨金属制造业职业伤害的瞬时危险因素。方法采用配对病例交叉研究的方法，研究对象为广东省中山市4个职业伤害定点医院收治的来自金属制造业的由机械压力导致的职业意外伤害患者208人，采集伤害发生前30min内危险因素的暴露情况，伤害发生前一天同一时段12种急性危险因素的暴露情况。结果采用条件logistic回归分析，结果显示，更换工作岗位（OR=20．76，95％CI=2．04—210．53），突然加班（OR=10．11，95％CI=2．57～39．75）是职业伤害的危险因素（P〈0．01），而其他危险因素没有统计学意义。结论更换工作岗位和突然加班是职业伤害的危险因素。[ Objective ] To study the transient risk factors for occupational injuries in metal manufacturing. [ Methods ] A matched case-crossover study was conducted in 208 patients who suffered from the occupational injuries caused by mechanical pressure in metal manufacturing, and were treated in four designated hospitals of occupational injury in Zhongshan City of Guangdong Province. The exposure status of risk factors within 30 minutes before the injury, and exposure status of 12 acute risk factors during same period on the day before injury were collected.[Results] The conditional logistic regression analysis showed that changing job （OR=20.76, 95%CI=2,04-210.53） and sudden overtime （OR=10.11, 95%CI=2.57-39.75） were the risk factors for occupational injury, while the statistical significance of other risk factors were not found. [ Conclusion ] Changing job and sudden overtime are the risk factors for occupational injury.
