Analysis of influencing factors of multi-site work-related musculoskeletal disorders in surgeons

Abstract

Objective To analyze the prevalence and influencing factors of multi-site work-related musculoskeletal disorders (WMSDs) in surgeons.

Methods A total of 102 surgeons from four hospitals were selected as study subjects by convenient sampling method. The Chinese version of Musculoskeletal Disorders Questionnaire was used to investigate the prevalence of WMSDs in the past one year, the related individuals and occupational factors.

Results The total prevalence of WMSDs among surgeons was 54.9%. The top three sites were neck (48.0%), lower back (35.3%) and shoulder (32.4%). The prevalence of WMSDs in multiple sites was higher than that in a single site (43.1% vs 11.8%, P<0.01). Multivariate logistic regression analysis showed that surgeons who smoked, were tired at work, and had a bent back had a higher risk of developing WMSDs [odds ratios and 95% confidence intervals were 3.66 (1.41-9.46), 8.33 (2.15-32.20), and 18.74 (2.14-166.77), all P<0.01] after excluding the influence of confounding factors.

Conclusion The prevalence rate of multi-site WMSDs among surgeons is high, and the influencing factors include bad living habits and occupational factors such as working load and working posture.

Abstract

摘要： 目的 分析外科医生多部位工作相关肌肉骨骼疾患(WMSDs)患病情况及其影响因素。 方法 采用方便抽样方 法, 选择 4 家医院 102 名外科医生为研究对象, 采用《中文版肌肉骨骼疾患调査表》电子问卷调査其过去 1 年中WMSDs患 病情况和有关个体因素、职业因素等。 结果 外科医生WMSDs总患病率为 54.9%; 患病率居前3位的部位依次为颈部 (48.0%)、下背部(35.3%)和肩部(32.4%); 多部位WMSDs患病率高于单一部位(43.1% vs 11.8%, P<0.01)。多因素logistic 回归分析结果显示, 排除混杂因素的影响后, 吸烟、工作时感到疲劳、背部弯曲的外科医生罹患WMSDs的风险相对较髙 [优势比及其95% 置信区间依次为 3.66(1.41∼9.46)、8.33(2.15∼32.20)、18.74(2.14∼166.77), P值均<0.01)]。 结论 外科 医生多部位WMSDs患病率较髙, 影响因素包括不良生活习惯和工作负荷、工作姿势等职业因素。
