摘 要: 目的 评估口腔医生工效学负荷水平,探讨其与工作相关肌肉骨骼疾患(WMSDs)的相关性。方法 采用《中国肌肉骨骼疾患问卷》调查口腔医生WMSDs的患病情况,采用快速上肢评估(RULA)法进行现场工效学评估,并分析其相关性。结果 口腔医生WMSDs患病率为56.1%,各部位患病率差异有统计学意义(X2=62.400,P<0.01),颈部最高;女性患病率高于男性(X2=16.020,P<0.01)。RULA法评估口腔医生工效学负荷平均得分为5.6±1.1,82.4%的口腔医生工效学负荷等级Ⅲ~Ⅳ级。多因素Logistic回归分析显示,工效学负荷Ⅲ级和Ⅳ级(OR=2.413、14.700)、女性(OR=3.670)、中级职称(OR=2.479)、身高<160 cm或≥175 cm(OR=3.708)均为WMSDs的危险因素。WMSDs患病率与工效学负荷之间存在相关性(P<0.05),患病率随工效学负荷的增加而递增。结论 工效学负荷是WMSDs的危险因素;口腔医生WMSDs患病率高,工效学负荷水平高,需予以关注并尽快加以改善。 |

Abstract: Objective To evaluate the ergonomic load of dentists and explore its correlation with work-related musculoskeletal disorders(WMSDs). Methods The prevalence of WMSDs in dentists was investigated by Chinese Musculoskeletal Disease Questionnaire,the ergonomic load was evaluated by rapid upper limb assessment(RULA),then to analyze their correlation. Results The results showed that the prevalence of WMSDs in dentists was 56.1%,there were some significant differences in the prevalence among various parts(X2=62.400,P<0.01),neck was the leading part,the prevalence in female was higher than that of male(X2=16.020,P<0.01). Furthermore,the average score of dentist's ergonomic load was 5.6±1.1 by RULA,and 82.4% of them reached grade Ⅲ or Ⅳ,and multivariate Logistic analysis showed that ergonomic load grade Ⅲ(OR=2.413)or Ⅳ(OR=14.700),female(OR=3.670),intermediate medical staffs(OR=2.479),too short(<160 cm)or too tall(≥175 cm)(OR=3.708)were all the risk factors for WMSDs in dentists. There was a definite relationship between prevalence of WMSDs and ergonomic load(P<0.05),and the prevalence increased with ergonomic load. Conclusion The results suggested that ergonomics load was a risk factor for WMSDs in dentists,dentists had higher WMSDs morbidity and higher ergonomic load,which needs to pay attention and make improvement as soon as possible. |
