Abstract: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.
“…Individual factors such as age, gender, tenure, anthropometric parameters, personal habits, etc. seem to pose risks for LBP [18,19]. The most commonly reported biomechanical risk factors with at least reasonable evidence for causing LBP include excessive repetition and awkward postures [20,21].…”
Work-related musculoskeletal injuries are one of the major occupational health issues of the workers, especially low back pain (LBP). The aim of this study was to survey the prevalence of LBP among manufacturing workers and to identify associations of individual and work-related factors with LBP. A cross-sectional questionnaire study was performed with 1173 participating manufacturing workers. The questionnaire included individual factors, psychosocial and physical exposures, and musculoskeletal discomfort. It was analyzed by logistic regression and structural equation modeling (SEM). The 1-year prevalence of LBP among Chinese manufacturing workers was 33.6%. Logistic regression analysis showed that job tenure, awkward postures, vibration and job demand were positively—while social support and job control were negatively associated with LBP (p < 0.05). The SEM results indicated that, as shown in other studies, job types, job tenure, postural load, high job demand, low job control and vibration were directly associated with LBP, but also that job types, high job demand, low social support and vibration may have indirect effects on LBP—mediated by postural load.

“…Office workers spend up to two-thirds of their working hours in sedentary postures [2]. This has negative effects on their health because they spend most of their wake time at work [3,4]. Musculoskeletal disorders (MSDs) present various symptom episodes and can happen in workers for many causes like excessive repetitions, high biomechanical and psychosocial demands, heavy lifting and social habits [4,5].…”

“…This has negative effects on their health because they spend most of their wake time at work [3,4]. Musculoskeletal disorders (MSDs) present various symptom episodes and can happen in workers for many causes like excessive repetitions, high biomechanical and psychosocial demands, heavy lifting and social habits [4,5]. MSDs manifest as pain and malfunction of the body structures and tissues; they are sometimes called repetitive strain injuries, and have a significant effect on the economy [6,7].…”
Background: Increase of musculoskeletal disorders is related to an economic burden; also elevate time spend in sedentary behavior can lead to a decrease in physical fitness and consequently an incidence in musculoskeletal disorders. The aim of the study was to evaluate if low lumbar traction strength and flexibility could predict musculoskeletal pain in university staff in two years. Methods: This is a longitudinal study with 2-year follow-up. Fifty-three university staff members participated in this longitudinal study: age = 38±8 years, height = 171±10 cm, body mass = 75±14 kg, and body mass index = 26±4 m/kg2. The participants performed the lumbar traction and the sit and reach tests, and completed the Corlett and Bishop body map and musculoskeletal pain questionnaire at baseline and two years later. Results: There was a 4% increase in pain prevalence on year 2, but 62% of the participants remained in the same pain classification. Men presented 11% decrease in lumbar traction strength, whereas women presented 21% decrease in strength. Flexibility level at baseline was not associated with developing pain. However, individuals in the lower 75th lumbar traction strength percentile at baseline had 3.2 higher odds of reporting musculoskeletal pain two years later than those in the higher 25th strength percentile. Conclusion: University staff presented decreases in lumbar traction strength and flexibility over a two year period. Weaker individuals at baseline were more likely to report musculoskeletal pain two years later than those who were stronger. Flexibility levels were not associated with developing pain.
“…However, there are still numerous amounts of challenges in understanding the association between musculoskeletal symptoms and various individual and occupational risk factors. Therefore, a cross-sectional study was carried out by Mehralizadeh, Dehdashti, and Kashani (2017) in Iran to examine the direct and indirect interactions of various risk factors with musculoskeletal complaints in hospital nurses. The study findings showed there was a personal effect of psychological, role-related, and work posture stressors on musculoskeletal complaints.…”

“…The study findings showed there was a personal effect of psychological, role-related, and work posture stressors on musculoskeletal complaints. 30 On the other hand, WMSD is a significant concern for public health, leading to temporary and permanent disability, and health care workers, including nurses, are at high risk for these disorders. Heidari, Borujeni, and Khosravizad (2018) conducted another crosssectional study among 300 nurses working in the teaching hospitals affiliated with Shiraz University of Medical Sciences (SUMS) to assess the health-promoting lifestyles of nurses and their association with musculoskeletal disorders and symptoms.…”
