本研究的目的是探讨上肢症状和键盘使用之间的关系，在人口调查。一份调查问卷邮寄给21 201名年龄在16-64岁的受试者，随机选择的34个英国全科诊所的登记册。收集了职业和经常使用键盘（平均工作日>4小时）、上肢和颈部疼痛、上肢麻木或刺痛、头痛以及疲劳或压力感的信息。相关性通过逻辑回归进行探讨，将所得比值比转换为患病率比（PR）。在12，262名受访者中，有4，899人从事非体力职业。其中包括1871名经常使用键盘的人（例如计算机操作员、数据处理员、办事员、管理员、秘书和打字员）。颈部或上肢疼痛和感觉症状在非体力劳动者中普遍存在（1周患病率分别为30%和15%），并与年龄较大、吸烟、头痛和疲劳或压力有关。在调整这些因素后，经常使用键盘与过去一周肩部（PR 1.2-1.4）和手腕或手部（PR 1.4）的疼痛显著相关，但与同期肘部疼痛或感觉症状无关，或者与过去一年中妨碍正常活动的颈部或上肢疼痛无关。残疾症状在有症状的键盘使用者中比在其他有症状的工人中更不普遍。我们的结论是，使用键盘与肩膀和手腕或手的不适有关，但风险估计低于工作场所调查中的普遍报道。以前对职业环境中风险的估计可能因共同的期望、关注或疾病行为的其他方面而有偏差。
The objective of this study was to examine the relationship between upper limb symptoms and keyboard use in a population survey. A questionnaire was mailed to 21 201 subjects aged 16-64 years, selected at random from the registers of 34 British general practices. Information was collected on occupation and on regular use of keyboards (for >4 h in an average working day), pain in the upper limbs and neck, numbness or tingling in the upper limbs, headaches, and feelings of tiredness or stress. Associations were explored by logistic regression, with the resultant odds ratios converted into prevalence ratios (PRs). Among 12 262 respondents, 4899 held non-manual occupations. These included 1871 regular users of keyboards (e.g. computer operators, data processors, clerks, administrators, secretaries and typists). Pain in the neck or upper limbs and sensory symptoms were common in the non-manual workers overall (with 1 week period prevalences of 30 and 15%, respectively), and were associated with older age, smoking, headaches and tiredness or stress. After adjustment for these factors, regular keyboard use was significantly associated with pain in the past week in the shoulders (PRs 1.2-1.4) and the wrists or hands (PR 1.4), but not with elbow pain or sensory symptoms over the same period, or with neck or upper limb pain that prevented normal activities in the past year. Disabling symptoms were somewhat less prevalent among symptomatic keyboard users than among other symptomatic workers. We conclude that use of keyboards was associated with discomfort at the shoulder and wrist or hand, but risk estimates were lower than generally reported in workplace surveys. Previous estimates of risk in the occupational setting may have been biased by shared expectations, concerns, or other aspects of illness behaviour.
