Statistics indicate a high risk of developing work-related musculoskeletal disorders among hospital nurses. The challenge is to understand the associations between musculoskeletal symptoms and various individual and occupational risk factors.
This study examined the direct and indirect interactions of various risk factors with musculoskeletal complaints in hospital nurses.
In a cross-sectional design, Iranian hospital nurses from Semnan University of Medical Sciences participated in a questionnaire survey reporting their perceived perceptions of various work-related risk factors and musculoskeletal symptoms. We tested our proposed structural equation model to evaluate the relations between latent and observed concepts and the relative importance and strength of exogenous variables in explaining endogenous musculoskeletal complaints.
Measurement model fits the data relatively acceptable. Our findings showed direct effects of psychological, role-related and work posture stressors on musculoskeletal complaints. Fatigue mediated the adverse indirect relations of psychological, role-related, work posture and individual factors with musculoskeletal complaints.
Structural equation modeling may provide methodological opportunities in occupational health research with a potential to explain the complexity of interactions among risk factors. Prevention of work-related musculoskeletal disorders among nurses must account for physical and psychosocial conditions.
统计数据表明，医院护士患与工作相关的肌肉骨骼疾病的风险很高。挑战在于了解肌肉骨骼症状与各种个人和职业风险因素之间的关联。
本研究探讨了医院护士中各种风险因素与肌肉骨骼不适之间的直接和间接相互作用。
采用横断面设计，来自塞姆南医科大学的伊朗医院护士参与了一项问卷调查，报告他们对各种与工作相关的风险因素和肌肉骨骼症状的感知。我们测试了我们提出的结构方程模型，以评估潜在概念与观察到的概念之间的关系，以及外生变量在解释内生性肌肉骨骼不适方面的相对重要性和强度。
测量模型与数据拟合度相对可以接受。我们的研究结果表明，心理、角色相关和工作姿势压力源对肌肉骨骼不适有直接影响。疲劳介导了心理、角色相关、工作姿势和个人因素与肌肉骨骼不适之间的不良间接关系。
结构方程建模可能为职业健康研究提供方法学机会，有潜力解释风险因素之间相互作用的复杂性。预防护士中与工作相关的肌肉骨骼疾病必须考虑身体和心理社会状况。
