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

本文分别于1996年、2002年和2007年对某金属制品厂蓝领工人的工作压力与职业伤害的关系进行了跟踪调查。参与人数、平均随访天数和工伤发生率分别为4312、570天，第一次调查23例，第二次调查4194、576天，24例，第三次调查3243、478天，15例。第一次和第二次调查的结果显示，抑郁量表得分低倾向于增加职业伤害的发生率，而最后一次调查的结果显示，得分高倾向于增加职业伤害的发生率。因此，为了防止职业伤害，我们认为应该注意抑郁症和工作压力等个人情况。

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.
