An earlier study of workers in fish-fillet plants in Iceland showed higher prevalence of musculoskeletal symptoms as compared to a random sample of the Icelandic population. Since that study a new manufacturing process, the flow-line, has been introduced. The aim of this study was to evaluate whether this new work situation changed the prevalence of musculoskeletal symptoms among the workers of the fish-fillet plants.
The same standardised Nordic Questionnaire was used in both surveys.
The monotony and the repetitiveness of the work increased with the new technique. The results showed that women had higher prevalence of symptoms of the upper limbs when working at the flow-line than before. The Mantel-Haenszel odds ratio for symptoms of elbows, fingers and wrists during the last seven days prior to the study was 2.1 (95% confidence interval (CI) 1.0-4.4), 1.9 (95% CI 1.1-3.2) and 1.7 (95% CI 1.0-2.7). The odds ratio for knees and ankles was less than one.
The higher prevalence of symptoms of the upper limbs seems to be causally related to the increase of monotonous and repetitive work in the fish industry.
一项对冰岛鱼片加工厂工人的早期研究表明，与冰岛人口随机样本相比，肌肉骨骼症状的患病率更高。自该研究以来，引入了一种新的制造工艺——流水线。本研究的目的是评估这种新的工作环境是否改变了鱼片加工厂工人中肌肉骨骼症状的患病率。
两次调查均使用相同的标准化北欧问卷。
随着新技术的应用，工作的单调性和重复性增加。结果显示，女性在流水线上工作时上肢症状的患病率高于以前。在研究前最后七天，肘部、手指和手腕症状的曼特尔 - 亨泽尔优势比分别为2.1（95%置信区间（CI）1.0 - 4.4）、1.9（95%CI 1.1 - 3.2）和1.7（95%CI 1.0 - 2.7）。膝盖和脚踝的优势比小于1。
上肢症状患病率较高似乎与渔业中单调和重复性工作的增加存在因果关系。
