The present study aimed to assess the prevalence of musculoskeletal disorders-caused by muscular work was performed in workers at a construction site. In this cross- sectional descriptive study, the prevalence of Work-related musculoskeletal disorders-in 199 construction workers at a construction site in 1390 at PARAND city, after identifying work stations and work tasks in construction workplaces, Nordic and demographics questionnaires were used for the determination of prevalence of musculoskeletal disorders and individual characteristics, respectively.

Musculoskeletal Disorders had significant association of the neck, with age, the shoulder with age and education level, elbow and experience with - education - body mass index, wrist and age with - experience - education level, body mass index, the upper back with age - Index BMI, body mass index, the knee with level of education with (p-value <0.05). Factors affecting the incidence of musculoskeletal disorders include prolonged labor, tools, inadequate and unsafe posture and manual handling.
