To study the effects of construction machinery operation on subjective symptoms, a questionnaire survey was carried out among construction machinery operators by a self-reporting method. Subjects were 184 power shovel operators, 127 bulldozer operators, 44 forklift operators as operator groups, and 44 office workers as a control. Their ages were in a range of 30-49 years. The questionnaire contained 20 symptoms referring to fatigue, digestive problems, and upper or lower limbs or back problems. The prevalence rate and symptom characteristics were examined. The dominant symptoms of the operator groups were stiff shoulder, low back pain, and stomach symptoms. The prevalence rate of low back pain was significantly different between forklift operators and controls. No significant differences were found in the symptoms of upper limbs and fingers between operator groups and controls. The prevalence of Raynaud's phenomenon was 0.5%-2.3% in the operator groups and 2.3% in the control group.
为研究建筑机械操作对主观症状的影响，采用自填式问卷调查法对建筑机械操作人员进行了调查。研究对象为184名电铲操作员、127名推土机操作员、44名叉车操作员作为操作员组，以及44名办公室职员作为对照组。他们的年龄在30至49岁之间。问卷包含20种涉及疲劳、消化问题以及上肢、下肢或背部问题的症状。对患病率和症状特征进行了检查。操作员组的主要症状为肩部僵硬、腰痛和胃部症状。叉车操作员与对照组之间腰痛的患病率存在显著差异。操作员组与对照组在上肢和手指症状方面未发现显著差异。雷诺现象在操作员组中的患病率为0.5%-2.3%，在对照组中为2.3%。
