Work-related risk factors and the prevalence of low back pain among low-income industrial workers in Bangladesh: results from a cross-sectional study

OBJECTIVES: Industrial workers are exposed to various musculoskeletal problems especially in tasks related to production. Low back pain is the main problem in most musculoskeletal disorders. Therefore, our study aims to identify the prevalence of work-related low back pain and its risk factors among industrial workers in Bangladesh. MATERIALS AND METHODS: A sample of 384 industrial workers aged 18–55 years in Bangladesh was selected to conduct this cross-sectional study to assess low back pain prevalence and identify its risk factors. Regression analysis was performed regarding socioeconomic status and risk factor related to LBP through interviews and questionnaires. RESULTS: Data analysis showed that the prevalence of LBP in industrial workers in Dhaka City was 238 (62%). Low back pain was associated with increasing age (odd ratio = 1.05). Other significant risks for pain in the low back were being a permanent employee (OR 3.15) and working more than 8 h (OR = 1.99). Also, LBP was associated with incorrect body mechanics use, repetitive bending, and continuous long-time sitting risk was higher than others. CONCLUSION: The results of this investigation highlight a high proportion of LBP and its risk factors among industrial workers in Dhaka City. Age, type of employment, working hours, use of incorrect body mechanics, repeated bending or twisting, and prolonged sitting were among the risk factors for back pain. Therefore, exercising, providing adequate training for properly maintaining body mechanics, and avoiding bad positions may be among the most powerful steps needed to avoid or prevent development of back pain.
