Self-reported symptoms in the neck and upper limbs of female assembly workers. Impact of length of employment, work pace, and selection.
研究148名女性装配工人与60名对照者的问卷数据，发现肩手疼痛率显著升高，工龄与手部不适强相关，年轻工人中工龄越长肩颈背痛越多，工作节奏快则肩颈痛风险增加但极快节奏下反而下降，26%离职者因疼痛离开。
In a questionnaire study 148 women in assembly work reported statistically significantly higher rates of pain, in the last 7 d, in their shoulders (odds ratio 3.4) and hands (odds ratio 2.8) as compared to 60 referents age-adjusted. There was a strong association between duration of employment and complaints in the hands. For the younger women, but not the older ones, there was an increase in pain in the shoulders, neck, and upper back with duration of employment. The odds ratio for pain in the shoulders and neck increased with an increasing work pace, except for very high paces, for which there was a decrease. Among 76 former assembly workers 26% reported pain as the cause of having left this work. There was no overall increase in the frequency of complaints among those who had left.
