A survey of 1540 forestry workers in Quebec found a prevalence of Raynaud's phenomenon of 30.5% among chain-saw users and 8.7% among nonusers. Prevalence was related directly to duration of use of the chain-saw. The mean interval (+/- the standard deviation) between the time the chain-saw was first used and the onset of Raynaud's phenomenon was 7.8 +/- 5.6 years. After 20 years of chain-saw use over 50% of the population had Raynaud's phenomenon. Relative risks among those using a chain-saw for more than 10 years were 3.60 for nonsmokers and 6.55 for smokers. Other factors associated with the phenomenon included a family history of nonoccupational Raynaud's phenomenon, previous injuries to the arms, climate and type of residence during the wood-cutting season. Decreased work capacity, interference with leisure activities and changes in professional orientation often resulted from this disease. These problems should be taken into account when disability compensation is being considered.
对魁北克省1540名林业工人的一项调查发现，使用链锯的工人中雷诺现象的患病率为30.5%，未使用链锯的工人中患病率为8.7%。患病率与链锯的使用时长直接相关。从首次使用链锯到出现雷诺现象的平均间隔时间（±标准差）为7.8±5.6年。使用链锯20年后，超过50%的人出现了雷诺现象。使用链锯超过10年的人群中，不吸烟者的相对风险为3.60，吸烟者为6.55。与该现象相关的其他因素包括非职业性雷诺现象的家族病史、手臂曾受过伤、伐木季节的气候和居住类型。工作能力下降、休闲活动受到干扰以及职业方向改变常常是由这种疾病导致的。在考虑伤残赔偿时应考虑到这些问题。
