Objective To understand the prevalence and influencing factors of musculoskeletal disorders of the back in nurses in a tertiary class A hospital of Tangshan.
Methods By the method of cluster sampling, 784 nurses in a tertiary class A hospital of Tangshan was investigated using a musculoskeletal disorders questionnaire on relevant symptoms and related frequencies, health impact, self-report on whether the illness is related to work, age, working and rest hours, work load, and job perception. Statistical analysis methods included t test, chi-square test, nonparametric test, and non-conditional logistic regression analysis.
Results The prevalence rate of nurses' musculoskeletal disorders of the back was 45.7%; pain in the back was a major symptom, accompanying half of the ailing nurses almost every day; 80.4% of the nurses believed that their health was affected. The musculoskeletal disorders of the back had positive correlations with age (OR=1.026, 95%CI:1.002-1.051), physical fatigue after work (OR=1.515, 95%CI:1.244-1.844), job satisfaction (OR=2.154, 95%CI:1.534-3.026), the times of repeating same action per hour (OR=1.042, 95%CI:1.016-1.067), and the number of patients served per day (OR=1.024, 95%CI:1.010-1.039); while negative association was with the days of off-work per month (OR=0.911, 95%CI:0.858-0.966).
Conclusion A high prevalence rate of musculoskeletal disorders of the back is identified in the nurses in the tertiary class A hospital, which might be related to higher work load, less off-work time, and the physical changes by aging.
