The association of low back pain (LBP) with mechanical factors at the workplace is uncertain. Most of the studies on this subject did not examine multiple levels of symptoms and did not take into account both the type of work and the primary activity during work. We studied the annual prevalence, severity and duration of attacks of LBP recorded on a physician-administered questionnaire in 208 workers in a pharmaceutical factory. Symptoms were then cross-tabulated with job type, location, work requirements, gender, and years at the factory. LBP was reported by 138 (66.3%) of the workers. Although over 75% of jobs in the packing department, laboratories and offices required prolonged sitting, LBP was most prevalent among workers in the packing department, where the chairs were found to be ergonomically unfit (odds ratio 3.7, 95% confidence interval 1.5-9.1, P = 0.003). Logistic regression demonstrated a highly significant and independent association between LBP and work in the packing or production department (odds ratio 2.03), sitting or lifting (odds ratio 1.97) and 6 years seniority (odds ratio 1.64). Gender was not a significant variable. We conclude that among these pharmaceutical company employees, prolonged sitting and work in the packing or production departments were independently associated with LBP. Prospective studies are warranted to substantiate our findings.
下背痛(LBP)与工作场所的机械因素之间的关联尚不确定。关于这一主题的大多数研究没有考察多个症状层面,也没有考虑工作类型和工作期间的主要活动。我们在一家制药厂的208名工人中,研究了通过医生填写的问卷记录的LBP发作的年患病率、严重程度和持续时间。然后将症状与工作类型、工作地点、工作要求、性别和在工厂的工作年限进行交叉制表。138名(66.3%)工人报告有LBP。尽管包装部门、实验室和办公室超过75%的工作需要长时间坐着,但LBP在包装部门的工人中最为普遍,那里的椅子被发现不符合人体工程学(优势比3.7,95%置信区间1.5 - 9.1,P = 0.003)。逻辑回归显示,LBP与在包装或生产部门工作(优势比2.03)、坐着或搬运(优势比1.97)以及6年工龄(优势比1.64)之间存在高度显著且独立的关联。性别不是一个显著变量。我们得出结论,在这些制药公司员工中,长时间坐着以及在包装或生产部门工作与LBP独立相关。需要进行前瞻性研究来证实我们的发现。
