Prevalence and associated risk factors of work related musculoskeletal disorders among Building construction workers in Shire Endaslassiae town, Northern Ethiopia
摘要
Construction industry is recognized as the main source providing jobs for laborers, but it is one of the highest-risk industries that require manual labor-intensive activities. Work-related musculoskeletal disorders are the leading occupational health problem of workers in the construction industry worldwide, with the highest prevalence in developing countries, including Ethiopia. It is estimated to account for approximately 77% work-related illnesses in construction workers. An Institutional based cross-sectional study design was conducted from March 5 to May 4, 2019 to evaluate work-related musculoskeletal disorders and associated factors among building Construction workers in Shire Endaslassiae, Ethiopia. Nordic musculoskeletal questionnaire was used to assess the 12-month prevalence of work-related musculoskeletal disorders. A simple random sampling method was employed to select 789 study participants. The data was entered using Epi-info version 7 and Bivariate and multivariable binary logistic regression analyses were performed using SPSS version 20. The study achieved a 95% (750) response rate. A sizable portion of respondents, 542(72%) (95%CI: 68.04, 75.08) were developed work-related musculoskeletal disorders at least once at any part of the body region during the last 12 months. Nearly five out of six 454(84%) males had developed work-related musculoskeletal disorders. Lower back (55.7%), Knee (33.5%), and Neck (29.2%) were the three leading body parts affected musculoskeletal system. Being untrained about occupational safety[AOR = 2.90, 95%CI: (1.65, 5.09)], dissatisfied in their work [AOR = 3.2, 95%CI: (1.73, 5.56)], higher work experiences[AOR = 3.1, 95% CI: (1.78, 5.43)], didn’t engage in physical exercises[AOR = 3.11, 95% CI: (1.62, 5.93)], and working longer than 8 h[(AOR = 4.1, 95% CI:2.04, 7.70)], become factors associated with prevalence of work-related musculoskeletal disorders. The prevalence of work-related musculoskeletal disorders among building construction workers is very high. Low back, knee, followed by neck were the most affected body parts, respectively. Work experience, job satisfaction, physical exercise, and work hours per day were statistically associated factors with musculoskeletal disorders at p-value ≤ 0.05. Implementing the Safety regulations, using site-specific ergonomic programs, and further investigation are recommended to reduce the effects of work-related musculoskeletal disorders.
