Using a cohort of 8183 postal workers, this study assesses the efficacy of preplacement medical examinations in defining the risk of occupational low back injuries. From this cohort, 154 subjects with occupational low back injuries between 1983 and 1988 and 942 control subjects who did not have low back injuries were identified. A multivariate logistic regression shows that a history of prior disability, odds ratio 2.90 (95% confidence interval 1.88-4.48), and a heavy lifting job, odds ratio 1.91 (1.32-276) are associated with occupational low back injuries. However, a history of previous back injury on screening examination is not associated with subsequent occupational injury. The association between a history of disability and occupational low back injury has not been previously noted and warrants further research.
本研究以8183名邮政工作人员为队列，评估入职前医学检查在确定职业性腰伤风险方面的有效性。在这个队列中，确定了1983年至1988年间154名患有职业性腰伤的受试者以及942名未患腰伤的对照受试者。多因素逻辑回归显示，既往残疾史（优势比2.90，95%置信区间1.88 - 4.48）和重体力劳动工作（优势比1.91，1.32 - 2.76）与职业性腰伤相关。然而，筛查检查中既往背部受伤史与随后的职业损伤无关。残疾史与职业性腰伤之间的关联此前未被注意到，值得进一步研究。
