This study aims to explore factors associated with low back pain (LBP) that required treatment from health care provider among non-emergency ambulance transfer workers.
A cross-sectional study was conducted to 38 workers of a major hospital in Hong Kong. The influences of four categories of risk factors (personal, physical, psychosocial, and exposure factors) in the prevalence of LBP were investigated by objective measurement and self-reported questionnaires. A modified Nordic musculoskeletal symptoms survey and sick leave record were used to document the prevalence of LBP. Univariate analyses followed by multiple logistic regression analyses were used to explore the risk factors associated with LBP cases.
The results revealed that LBP was associated with age (OR=0.75, CI=0.56-1.00, P < 0.05), perceived effort (OR=7.95, CI=1.46-43.27, P < 0.05), job satisfaction (OR=4.18 CI=1.42-12.33, P < 0.01), and flexor peak torque at 120 degrees /s (OR=1.09 CI= 0.99-1.19, P=0.07).
This study suggests that workers' perceived exertion has an valuable role in assessing risk at this workplace. A high perceived exertion at work can signal the need for work adjustment or modification to avoid progression of low back disorder to persistent pain or intense pain. The effects of work adjustment or modification in affected workers needs to be systematically investigated.
本研究旨在探讨非紧急救护转运工作人员中需要医疗保健提供者治疗的腰痛（LBP）相关因素。
对香港一家大型医院的38名工作人员进行了横断面研究。通过客观测量和自我报告问卷，调查了四类风险因素（个人、身体、心理社会和暴露因素）对腰痛患病率的影响。使用改良的北欧肌肉骨骼症状调查和病假记录来记录腰痛的患病率。采用单因素分析，随后进行多因素逻辑回归分析，以探讨与腰痛病例相关的风险因素。
结果显示，腰痛与年龄（OR = 0.75，CI = 0.56 - 1.00，P < 0.05）、感知努力程度（OR = 7.95，CI = 1.46 - 43.27，P < 0.05）、工作满意度（OR = 4.18，CI = 1.42 - 12.33，P < 0.01）以及120度/秒时的屈肌峰值扭矩（OR = 1.09，CI = 0.99 - 1.19，P = 0.07）有关。
本研究表明，工作人员的感知用力程度在评估该工作场所的风险方面具有重要作用。工作中较高的感知用力程度可能表明需要调整或修改工作，以避免下背部疾病发展为持续性疼痛或剧烈疼痛。需要系统地研究对受影响工人进行工作调整或修改的效果。
