Data were analyzed using single and multivariate logistic regression. Findings: The prevalence of MSDs was reported 116 (75.8%) among the study subjects. Weight is an individual factor that increases the prevalence of MSDs to 17 times alone and in combination with other risk factors, increases the absence from the work and refer to doctors to 3.6 and to 36 times respectively.
