en Associated factors of nonspecific low back pain in occupational health settings Occupational Health Occupational Health پژوهشي Research Article Background & Aims: Non-specific low back pain (NSLBP) is one of the most prevalent musculoskeletal issues, significantly impacting workers’ quality of life and occupational productivity. This multifactorial condition arises from a combination of occupational, lifestyle, and individual factors. This study aimed to investigate the prevalence and associated factors of NSLBP among workers. Materials & Methods: This cross-sectional study was conducted on 406 participants, including 202 workers with NSLBP and 204 without. Demographic and occupational questionnaires, along with the Work Ability Index and Job-Related Physical Demands scales, were completed by all participants. Data were analyzed using descriptive and inferential statistical methods. Results: Significant associations were identified between longer weekly working hours (p < 0.001), lack of physical activity (p = 0.001), and exposure to occupational hazards (p < 0.05) and NSLBP. Workers exposed to these factors were at a higher risk of developing NSLBP. Conclusion: NSLBP is significantly associated with a combination of individual and occupational factors. The findings highlight the necessity of preventive interventions, including ergonomic workplace improvements, reduced weekly working hours, and the promotion of regular physical activity. These results can inform occupational health policies and enhance workers’ quality of life. However, the study’s limitations, including its cross-sectional design and relatively small sample size, should be considered when interpreting the findings. <div style="border-bottom:solid windowtext 1.0pt; padding:0mm 0mm 1.0pt 0mm"></div> Ergonomics, Low back pain, Occupational groups, Occupational health 103 111 http://hsm.umsu.ac.ir/browse.php?a_code=A-10-260-2&slc_lang=en&sid=1 Mashallah Aghilinejad dr.maghilinejad@yahoo.com 10031947532846003664 10031947532846003664 No Occupational Medicine Research Center, Iran University of Medical Sciences, Tehran, Iran Mostafa Farhadi mfarhadi111@gmail.com 10031947532846003665 0009-0008-9753-8048 No Department of Occupational Medicine, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Mohammadreza Ganjedanesh mrgd313@gmail.com 10031947532846003666 10031947532846003666 No Department of Occupational Medicine, School of Medicine, Iran University of Medical Sciences, Tehran, Iran Amir Bahrami-Ahmadi bahramia@gmail.com 10031947532846003667 10031947532846003667 No Occupational Medicine Research Center, Iran University of Medical Sciences, Tehran, Iran Mohammad Eslami Mhm.eslami99@gmail.com 10031947532846003668 10031947532846003668 No Faculty of Medicine, Iran University of Medical Sciences, Tehran, Iran Negin Kassiri neginkassiri@gmail.com 10031947532846003669 10031947532846003669 Yes Occupational Medicine Research Center, Iran University of Medical Sciences, Tehran, Iran
