Musculoskeletal Symptoms Prevalence & Associated Physical Risk Factors: A Cross Sectional Study among Automobile Mechanics

Abstract

BACKGROUND: The magnitude of work-related health problem can be reduced by taking proper strategies and effective management such as ergonomic intervention. Statistics on musculoskeletal symptoms prevalence can help to develop concrete and effective program. However, there is no information about the musculoskeletal symptoms prevalence and associated physical risk factors among the automobile mechanics in Bangladesh. AIM: The aim of this study was to determine the prevalence & associated risk factors of musculoskeletal symptoms among automobile mechanics. METHOD: A cross-sectional study was performed with 100 automobile mechanics conveniently selected from Savar & Gabtali. Two questionnaires were used for the study. The DMQ was used to determine the prevalence & the REBA was used to identify the physical risk level of musculoskeletal symptoms among automobile mechanics. RESULT: The prevalence of musculoskeletal symptoms during the last 12 months preceding data collection was reported 77% & at last 7 days was 81%. The most affected body parts was hips then the lower back & others were respectively. Sociodemographic factors were found to be significantly associated with musculoskeletal symptoms. Similarly, awkward posture, repetitive movement, force exertion, lifting & vibration were significantly associated to reports of musculoskeletal symptoms for the last 12 months & 7 days preceding data collection. CONCLUSION: Results conclude that there is a high prevalence of musculoskeletal symptoms among automobile mechanics. The magnitude of musculoskeletal problem can be reduced by taking proper strategies and effective ergonomic management.
