en بررسی تاثیر انواع مداخلات ارگونومیک بر شاخصهای بهداشتی در یک صنعت لاستیکسازی Effects of Ergonomic Interventions on Health Indicators in a Rubber Industry تخصصي Special پژوهشي Research <div dir="ltr">Background and purpose: This study was conducted with the aim of determining the impact of engineering, organizational and individual ergonomic interventions on the indicators of the percentage of workers complaining of musculoskeletal problems, having an inappropriate work station, exposure to inappropriate manual handling, and also the percentage of sick leave in workers of a rubber industry.</div> <div dir="ltr">Materials and methods This is a descriptive-analytical and retrospective study that was conducted in the production department of a rubber manufacturing industry. Ergonomic interventions that have been fully implemented in the industry and have been stable were included in the study, and data were extracted by examining the documentation related to ergonomic assessment tools before and after each intervention. Before and after comparison of indicators was done using paired t and Wellcoxon tests.</div> <div dir="ltr">Results Ergonomic interventions included 114 engineering interventions, 20 organizational interventions and 7 individual interventions. Engineering interventions had a significant effect on all indicators such as in reducing total musculoskeletal problems  )66%). Organizational interventions  has led to the improvement of the index of musculoskeletal problems (60%), inappropriate posture (55%) and  pain intensity (30%). Individual interventions also had a significant effect on musculoskeletal problems (85.71%), pain intensity (42.85%) and sickleaves (100%) (P<0.05). Conclusion All three types of ergonomic interventions in the production sector of the rubber industry have been effective in reducing musculoskeletal problems. Engineering interventions have had a significant impact on all the health indicators considered in this study. Engineering interventions in the rubber industry are more effective and it is better to be implemented together with organizational or individual interventions to complete the effectiveness.</div> Background: This study aimed to determine the impact of engineering, organizational, and individual ergonomic interventions on the percentage of workers complaining Musculoskeletal disorders, inappropriate work environment, exposure to manual handling, and the rate of sick-leave in workers of rubber industry. Methods: This was a descriptive-analytical and retrospective study conducted in the production department of a rubber manufacturing industry. Ergonomic interventions, which have been fully implemented and have been stable in the industry, were included in the study. Health indicators were determined by reviewing completed Nordic questionnaires, insurance documents, and the documents about different methods of ergonomic risk assessment before and after each intervention. Before and after comparing the indicators, paired t and Wilcoxon tests were done. Results: Ergonomic interventions included 114 engineering, 20 organizational, and 7 individual interventions. Engineering interventions had a significant effect on all the indicators such as reducing total MSDs) 66%). Organizational interventions led to the improvement of the index of MSDs (60%), inappropriate posture (55%) and pain intensity (30%). Individual interventions had a significant effect on MSDs (85.71%) and sick-leaves (100%) (P<0.05). Conclusion: All the types of ergonomic interventions in the production sector of the rubber industry have been effective in reducing MSDs. Engineering interventions have had a significant impact on all the health indicators considered in this study; they are highly effective in the rubber industry, and it is better to implement them together with organizational or individual interventions for better results.   مهندسی عوامل انسانی, بیماری های اسکلتی عضلانی, آموزش بهداشت Musculoskeletal Diseases, Organizational Innovation, Health Education, Manufacturing Industry 1401 1412 http://aoh.ssu.ac.ir/browse.php?a_code=A-10-350-1&slc_lang=en&sid=1 Mina-sadat Behdani میناسادات بهدانی No School of Public Health and Safety, Shahid Beheshti University of Medical Sciences, Tehran, Iran دانشکده بهداشت و ایمنی علوم پزشکی شهید بهشتی Reza Gholamnia رضا غلام نیا reza_gholamnia@yahoo.com Yes Department of Health, Safety and Environment, School of Public Health and Safety, Shahid Beheshti University of Medical Sciences, Tehran, Iran دانشکده بهداشت و ایمنی علوم پزشکی شهید بهشتی Mahnaz Saremi مهناز صارمی saremim@yahoo.com No Department of Ergonomics, School of Public Health and Safety, Shahid Beheshti University of Medical Sciences, Tehran, Iran دانشکده بهداشت و ایمنی علوم پزشکی شهید بهشتی
