Study on the influence of job stress on occurrence of occupational injury

我们分别从1996年、2002年和2007年开始，对某金属制品厂蓝领员工的工作压力与职业伤害发生率之间的关系进行了跟踪调查。第1次调查参与人数为4312人，平均随诊天数为570天，第1次调查为23例，第2次调查为4194人，平均随诊天数为576天，第2次调查为24例，第3次调查为3243人，平均随诊天数为478天，职业伤发生率为15例。与第一次和第二次调查的结果相反，在第一次和第二次调查中，抑郁量表中的低分倾向于职业伤害发生率的增加，而在上一次调查中，高分与职业伤害发生率的增加显著相关。因此，从预防职业伤害的角度来看，我们认为个人情况，如抑郁和工作压力，都应该受到关注。

We conducted three surveys as follow-up on the relationship between job stress and incidence of occupational injury in blue-collar employees in a metal-product factory, starting in 1996, 2002, and 2007 respectively. The number of participants, mean number of follow-up days and incidence of occupational injury were 4312, 570 days, 23 cases in the first survey, 4194, 576 days, 24 cases in the second, and 3243, 478 days, 15 cases in the third, respectively. In contrast to the results of the first and second surveys where low scores in the depression scale tended toward increased incidence of occupational injury, high scores related significantly to augmented incidence of occupational injury in the last survey. Therefore, with a view to preventing occupational injury, we consider that personal conditions such as depression, as well as job stress, should be paid attention to.
