目的通过对养路工主观疲劳症状和疲劳客观指标血清中IL-6浓度进行检测,了解养路工疲劳状况,并探讨养路工职业暴露对疲劳的影响。方法采用《疲劳自评问卷表》对养路工(油路工51人、水泥路工76人)和行政管理人员(42人)的主观疲劳进行问卷调查,用酶联免疫法定量检测血清中IL-6浓度。结果养路工组主观疲劳总得分和躯体因子A得分明显高于对照组(P<0.01),主观疲劳检出率油路组(29.4%)和水泥路组(25.0%)明显高于对照组(P<0.05);血清中IL-6浓度养路工组高于对照组,且水泥路组〔(74.1±21.5)pg/ml〕与对照组〔(65.9±17.3)pg/ml〕比较,差异有统计学意义(P<0.05)。结论养路工主观疲劳得分、主观疲劳检出率以及血清中IL-6浓度均高于对照组,疲劳已成为危害养路工健康的一个重要指标。
Objective To investigate the fatigue status of maintenance workers by examining the subjective fatigue symptoms and the objective indicators of fatigue IL-6 in maintenance workers, and to explore the effect of occupational exposure on road maintenance workers on fatigue. Methods A questionnaire survey on the subjective fatigue of maintenance workers (51 road workers, 76 cement road workers) and administrative staff (42 workers) was carried out by using the fatigue self-assessment questionnaire. Serum IL -6 concentration. Results The scores of subjective fatigue score and somatosensory factor A in maintenance group were significantly higher than those in control group (P <0.01). Subjective fatigue detection rate was significantly higher in oilway group (29.4%) and cement road group (25.0%) than that in control group P <0.05). The concentration of IL-6 in serum was higher than that of the control group (P <0.05), and the difference was statistically significant compared with the control group [(74.1 ± 21.5) pg / ml〕 Statistical significance (P <0.05). Conclusion The fatigue score of subordinate road maintenance workers, the detection rate of subjective fatigue and the concentration of IL-6 in serum are higher than those of the control group, and fatigue has become an important index that endanger the health of road maintenance workers.
