Evaluating the Role of Risk Factors on the Prevalence and Consequence of Musculoskeletal Disorders in Female Hairdressers in Qazvin: a Structural Equation Modeling Approach

Background & objectives: Musculoskeletal disorders are one of the common causes of occupational injury and disability among various occupations.Hairdresser in their careers faces many harmful factors, including musculoskeletal disorders, especially in the neck, waist and shoulder areas.The aim of this study was to evaluate the role of individual and occupational risk factors on the prevalence and consequence of musculoskeletal disorders in female hairdressers in Qazvin with a structural equation modeling approach.Methods: In this cross-sectional study, 153 participants were recruited from Qazvin female hairdressers.The structural equation modeling in LISREL software (version 8.8) was used to determine the effect of risk factors on the prevalence and consequence of musculoskeletal disorders, Results: Based on modeling results, age, body mass index, weight and work experience showed a positive relationship.On the other hand, work ability index showed negative relationship with musculoskeletal pain and its consequences.Demographic and occupational variables are main predictor of (82%) of musculoskeletal disorders, absence from work and visiting a doctor among female hairdressers.Conclusion: Considering that more than half of the hairdressers are suffering from neck and waist discomfort and about one-third of them suffering from shoulder discomfort, so modifying their work situation are necessary.82% of the pressure on the limbs can be reduced by reducing the retirement age, maintaining proper weight, and increasing the ability to do work.The prevalence of musculoskeletal disorders, visits to the doctor, and the absence from work can be reduced.
