Several studies have found that inappropriate workstations are associated with musculoskeletal disorders. The present cross-sectional study aimed to identify the risk factors of non-specific neck pain (NP) and low back pain (LBP) among computer-using workers.
Observational study with a cross-sectional sample.
This study surveyed 15 companies in Zhejiang province, China.
After excluding participants with missing variables, 417 office workers, including 163 men and 254 women, were analyzed.
Demographic information was collected by self-report. The standard Northwick Park Neck Pain Questionnaire and Oswestry Low Back Pain Disability Index, along with other relevant questions, were used to assess the presence of potential occupational risk factors and the perceived levels of pain. Multinomial logistic regression analysis, adjusted for age, sex, body mass index, education, marital status and neck/low back injury, was performed to identify significant risk factors.
Compared with low-level NP, the computer location (monitor not in front of the operator, but on the right or left side) was associated with ORs of 2.6 and 2.9 for medium- and high-level NP, respectively. For LBP, the computer location (monitor not in front) was associated with an OR of 3.2 for high-level pain, as compared with low-level pain, in females. Significant associations were also observed between the office temperature and LBP (OR 5.4 for high vs low), and between office work duration ≥5 years and NP in female office workers (OR 2.7 for medium vs low).
Not having the computer monitor located in front of the operator was found to be an important risk factor for NP and LBP in computer-using female workers. This information may not only enable the development of potential preventive strategies but may also provide new insights for designing appropriate workstations.
多项研究发现，不合适的工作岗位与肌肉骨骼疾病有关。本横断面研究旨在确定使用计算机的工作人员中非特异性颈部疼痛（NP）和下背部疼痛（LBP）的危险因素。
采用横断面样本的观察性研究。
本研究对中国浙江省的15家公司进行了调查。
在排除变量缺失的参与者后，对417名办公室工作人员进行了分析，其中包括163名男性和254名女性。
通过自我报告收集人口统计学信息。使用标准的诺斯维克公园颈部疼痛问卷和奥斯威斯下背部疼痛残疾指数，以及其他相关问题，来评估潜在职业危险因素的存在情况和疼痛感知水平。进行多因素logistic回归分析，并对年龄、性别、体重指数、教育程度、婚姻状况和颈部/下背部损伤进行校正，以确定显著的危险因素。
与低水平NP相比，计算机位置（显示器不在操作员前方，而是在右侧或左侧）与中、高水平NP的比值比分别为2.6和2.9。对于LBP，在女性中，与低水平疼痛相比，计算机位置（显示器不在前方）与高水平疼痛的比值比为3.2。在办公室温度与LBP之间（高与低相比，比值比为5.4），以及女性办公室工作人员的办公室工作时长≥5年与NP之间（中与低相比，比值比为2.7）也观察到显著关联。
发现计算机显示器不在操作员前方是使用计算机的女性工作人员发生NP和LBP的重要危险因素。这些信息不仅可以促进潜在预防策略的制定，还可能为设计合适的工作岗位提供新的见解。
