To determine which proposed risk factor, work activity (industrial v clerical), body mass index (BMI), or other demographic factors had the most influence on the prevalence of median mononeuropathy at the wrist, and if there was an interaction between the risk factors.
This was a cross sectional study of active workers at five different worksites; four were industrial sites and one was clerical. 527 workers were recruited--164 clerical and 363 industrial. The presence of a median mononeuropathy in either hand was measured by electrodiagnostic techniques comparing median and ulnar sensory latencies.
30% of workers had an abnormality of the median sensory nerve at the wrist (34% of the industrial v 21% of the clerical workers). The adjusted risk for industrial workers was twice that of clerical workers. Obese workers (BMI > 29) were four times more likely to present with a median mononeuropathy than workers who were normal or slender (BMI < 25). There was no significant interaction between BMI and worksite in relation to median mononeuropathy. Increasing age was also related to an increased risk of median mononeuropathy.
Obesity, industrial work, and age are independent risk factors that influence the prevalence of median mononeuropathies among active workers.
确定以下哪个因素对腕部正中单神经病患病率影响最大：工作活动（工业工作与文职工作）、体重指数（BMI）或其他人口统计学因素，以及这些危险因素之间是否存在相互作用。
这是一项针对五个不同工作场所在职员工的横断面研究；四个是工业场所，一个是文职场所。共招募了527名员工——164名文职人员和363名工业工人。通过比较正中神经和尺神经感觉潜伏期的电诊断技术来检测双手是否存在正中单神经病。
30%的员工腕部正中感觉神经存在异常（工业工人中为34%，文职人员中为21%）。工业工人的校正风险是文职人员的两倍。肥胖员工（BMI>29）出现正中单神经病的可能性是正常或体型苗条员工（BMI<25）的四倍。就正中单神经病而言，BMI与工作场所之间没有显著的相互作用。年龄增长也与正中单神经病风险增加有关。
肥胖、工业工作和年龄是影响在职员工正中单神经病患病率的独立危险因素。
