Abstract
Background: Work-related Musculoskeletal Disorders (WMSD) is one of most prevalent health problems among individuals with limited physical activity. This study aimed to assess this problem among office workers in Shahid Beheshti University of Medical Sciences in Tehran, Iran. Methods and Material: Totally, 42 eligible office workers from three health centers related to ShahidBeheshti University of Medical Sciences(SBUMS) between May, 2016-September, 2016 were recruited in this cross-sectional study. Of all these individuals, 420 office workers (response rate 99.2%) were satisfied to participate in this study. In Standard Nordic questionnaire were used to collect data. Collected data were entered into SPSS 16 and analyzed through descriptive and analytical tests. Results: Totally, 420 office workers with a mean age of37.1 ± 8.03 were examined in this study.The most prevalent WMSPD waslower back pain (N = 56, 13.3%) followed by neck pain (N = 46, 11.0%), wrist pain (N = 43, 10.2%), hip pain (N = 6, 1.4%) and pain in heel of foot (N = 17, 4%). The variables such as age (χ2 = 24.99: P = 0.003); gender (χ2 = 0.544; P = 0.028); employment status (χ2 = 9.837: P = 0.007); duration of pain (χ2 = 1.55l P = 0.001) and duration of treatment (χ2 = 1.006; P=0.001) were significantly related to WMSD. Conclusions: Since the WMSD are prevalent among office workers of SBUMS, designing proper interventional studies are recommended. However, doing more researches to confirm the results of this study is guaranteed.

Abstract
Aim: Ergonomic risk factors play an important role in prevalence of Work-related MusculoSkeletal Disorders (WMSDs). Due to housewives’ different tasks at home, they seem to be exposed to different safety and health risk factors. The aim of the present study is assessment of risk and WMSDs prevalence in housekeeping job.
Method and Materials: In this study, first, the task and subtask of housekeeping job were analyzed by Hierarchical Task Analysis (HTA) method. Then the postures of 100 housewives were assessed by Rapid Entire Body Assessment (REBA) method and finally, the prevalence of WMSDs was investigated using the Nordic Questionnaire (NQ).
Findings: The REBA score for housewives in three tasks of dusting (worst posture), hovering and floor squeegeeing (longest posture) was 8 (high), 2, and 2 (low), respectively. The highest prevalence of WMSDs was reported in the lower back and neck. Significant relationship was observed between Low Back Pain (LBP) and stand-sit activity.
Conclusion: This study showed high prevalence of WMSDs symptoms in study population, especially in their lower back and neck. In addition, it was indicated that the working conditions of housewives need to be improved. It is recommended to train individuals to identify ergonomic risk factors and use proper ergonomic principles and procedures to prevent WRMSDs in housework.

Abstract
Aim: An Objective measure of ergonomic risk factors in the workplace performs a significant role in preventing the prevalence of Work-related Musculoskeletal Disorders (WMSDs). Hairdressers are exposed to various safety and health risk factors due to the nature of their job. This study aimed to assess the risk of prevalence of WMSDs in female hairdressers.
Method and Materials: In this study, the physical postures of 70 female hairdressers were assessed using Rapid Upper Limb Assessment (RULA) and Novel Ergonomic Postural Assessment (NERPA) and then the Nordic Questionnaire (NQ) was used to assess the prevalence of WMSDs.
Findings: RULA and NERPA final score in the worst and longest postures for hairdressers was 7. The highest prevalence of WMSDs was reported in the shoulder, knee and, neck area of the body. There was a significant relationship between hairdresser’s age and the prevalence of WMSDs in the shoulders, back, waist, knees and, ankles areas. The prevalence of WMSDs was found to have a significant relationship with standing-sitting activities.
Conclusion: The findings of this research revealed that the study population had a high prevalence of WMSDs, especially in the shoulder, knee and, neck areas. This study suggested that the conditions of the workplace should be improved. Therefore, in addition to improving working conditions, it is recommended that hairdressers be trained in identifying workplace hazards and so using proper ergonomic standards while working.

Abstract
Aim: Exposure to ergonomic risk factors in the workplace is one of the most common causes of Work-related MusculoSkeletal Disorders (WMSDs). Since gardeners and landscaping workers are exposed to WMSDs due to the different tasks they perform, this study aims to assess the risk of WMSDs prevalence among this group.
Methods and Materials: In this study, first, the job tasks of workers were analyzed using the Hierarchical Job Analysis (HTA) method. Then, the job postures of 100 gardening and landscape workers in one of the industrial complexes of Yazd province were assessed using the Rapid Entire Body Assessment (REBA) method. Finally, the Nordic Questionnaire (NQ) was used to estimate the prevalence of WMSDs. SPSS software version 22 was used for data analysis.
Findings: The REBA final score for the two activities of mowing (worst posture) and leaves collection (longest posture) were 8 (high) and 4 (medium), respectively. The highest prevalence of WMSDs was in the lower back and knee areas. A significant relationship was found between aging and the prevalence of WMSDs in the neck and wrist area. Furthermore, a relationship was found between severity of WMSDs in the elbow area and the type of work activity.
Conclusion: The working conditions of these workers should be examined and corrected from the ergonomic issues point of view. It is recommended that people be trained to understand the occupational ergonomics hazards and how to reduce the risk of developing WMSDs through the proper use of ergonomic principles.

Abstract
Aims: Farmers are one of the high-risk occupational groups in terms of Work- related MusculoSkeletal Disorders (WMSDs). Many factors such as ddemographic and physical characteristics and lifestyle are effective in incidence of these disorders in farmers. The aim of this study is to investigating the prevalence of WMSDs and related factors among this target group.
Method and Materials: The data of this study was extracted from The Ravansar Non-Communicable Diseases (RaNCD) cohort study that was performed on 10,000 people aged 35 to 65 years in Ravansar, Iran. Version 23 of SPSS software was used for data analysis.
Findings: The prevalence of back pain in farmers was 31. 3%, back stiffness was 17.7%, joint pain was 37.3%, joint stiffness was 12.3% and spinal disorder was 22% included lordosis (15%) and kyphosis (7.3%). There was a significant relationship between gender, age and all disorders. There was no significant relationship between marital status, sleep status, alcohol consumption, Body Mass Index (BMI), weight and height, and any of the disorders. There was no significant relationship between education level, the type of residence, smoking and drug use, type of home ownership, internet use and some of disorders but there was a significant relationship between these factors and the other disorders.
Conclusion: Considering the significant prevalence of WMSDs in farmers, it is necessary to perform ergonomic interventions in the form of occupational health training programs, in order to raising farmers’ awareness and skills to prevent the disorders.

Abstract
Aim: One of the major global occupational diseases and injuries is musculoskeletal disorders, which leads to increased costs and reduced working productivity. It is essential to assess the risk factors that influence development of these diseases. The purpose of this study was to determine the relationship between risk factors affecting work-related musculoskeletal disorders (WMSDs) in the food industry using the Fuzzy DEMATEL method.
Methods: In this study, 46 occupational risk factors related to musculoskeletal disorders in the food sector were selected from related articles and classified according to the 4m method. Fuzzy DEMATEL study is designed and delivered to experts. Finally, these risk factors were evaluated using the Fuzzy DEMATEL method.
Findings: The cause- effect relationship between 46 risk factors was determined using the Fuzzy DEMATEL method. According to results, the age factor (D-R=2.26) has a greater influence compared to other identified risk factors (is the most causal) and the job satisfaction factor compared to other identified risk factors, is the most influential factor (D-R=-2.26). According to the results, the most important risk factor is the duration of work (D+R=7.46) and the least important is related to the genetic risk factor (D+R=2.64).
Conclusion: The DEMATEL method allows us to better plan and solve problems. In this way, in order to better understand cause-effect relationships, we can divide several criteria into cause-effect groups to build a correlation map.
