The purpose of the study was to evaluate both nonoccupational and occupational factors associated with carpal tunnel syndrome (CTS) in industrial workers.
Sixty-five workers with CTS were compared with 65 referents matched for gender, age, and plant. The medical history and household activities of the workers and the ergonomic and organizational characteristics of the job were analyzed.
Exertion of force over 1 kg was associated with CTS [odds ratio (OR) 9.0]. Two risk factors were related to motion repetitiveness: length of the shortest elementary operation of < or = 10 s (OR 8.8) and lack of change in tasks or lack of breaks for at least 15% of the daily worktime (OR 6.0). No posture of the upper limb was associated with CTS. Workstation design involving the manual supply of the workers (OR 5.0) and the lack of job rotation (OR 6.3) were associated with CTS. The only personal factor associated with CTS was a parity of at least 3 (OR 3.2). There was a continuous increase in the odds ratio against the number of risk factors accumulated by the workers; the odds ratio thus ranged from 5.6 when 3 of the 6 risk factors were present to > or = 90 when 4, 5, or 6 risk factors were accumulated.
The results were in agreement with a model for CTS which included 1 personal and 5 occupational risk factors. The number of risk factors cumulated by the workers seems to be a major determinant of CTS.
本研究旨在评估与产业工人腕管综合征（CTS）相关的非职业因素和职业因素。
将65名患有CTS的工人与65名在性别、年龄和工厂方面相匹配的对照者进行比较。分析了工人的病史和家庭活动，以及工作的人体工程学和组织特征。
用力超过1千克与CTS相关[比值比（OR）为9.0]。有两个风险因素与动作重复性有关：最短基本操作时长小于或等于10秒（OR为8.8），以及至少15%的工作日缺乏任务变化或休息（OR为6.0）。上肢的任何姿势均与CTS无关。涉及工人手工供应的工作站设计（OR为5.0）和缺乏工作轮换（OR为6.3）与CTS相关。与CTS相关的唯一个人因素是生育次数至少为3次（OR为3.2）。随着工人累积的风险因素数量增加，比值比持续上升；因此，当存在6个风险因素中的3个时，比值比为5.6，而当累积4个、5个或6个风险因素时，比值比大于或等于90。
结果与一个包含1个个人风险因素和5个职业风险因素的CTS模型相符。工人累积的风险因素数量似乎是CTS的主要决定因素。
