Abstract
Background: Attention to the workstations of the employees and their quality of work life has become increasingly important due to the increased competition in the organizations. The present study aimed to investigate the relationship between the ergonomic situation of the workstations and musculoskeletal disorders with the quality of work life and demographic variables in the administrative staff of the Tehran Municipality.
Methods: The present study was a descriptive and analytical one. The statistical population included a total of 600 persons, working in one of the regions in the Tehran Municipality. Of the 600 staff, a total of 255 were selected as the available sample group. The instruments consisted of the questionnaires, including the individual and occupational information, the Nordic questionnaire, the Walton Quality of work life, and the checklist of the ergonomic indices of the working environment for the administrative staff. In order to analyze the data, Student’s t-test and multiple regression analysis were used.
Results: In this study, the majority of the samples were females (56.9%) with a mean age of 33 years. A significant positive relationship was observed between all the ergonomic indices and the quality of work life. Significant correlations among the parameters such as age, education, sleeping at night, psychological conditions, musculoskeletal disorders of the neck, shoulder, and foot were observed simultaneously with the quality of work life. The quality of work life of an employee could be predicted through the musculoskeletal disorders and demographic variables but could not be predicted by the ergonomic indicators.
Conclusion: In this study, a relationship existed between the ergonomic condition of the workstations and musculoskeletal disorders with the quality of work life and demographic variables. Therefore, the physical condition and the quality of the work life of the employees would be positively affected by the improvement of the ergonomic condition of the workstations.

Abstract
Background: The working station has a major impact on the musculoskeletal disorders, therefore a considerable attention to working station staff is of importance. The aim of this study was to investigate the effect of working station on musculoskeletal disorders among administrative staff.
Methods: 30 administrative staff participated in this analytical descriptive study. Data was collected using Nordic Musculoskeletal Disorders Questionnaire (NMQ) in ergonomic design intervention of three working stations (sitting, standing-and-sitting, standing) before and after of intervention. Moreover, a t-test and multiple regression were used to analyze the data.
Results: The average (standard deviation) of the age and work record of 30 participating employees were 44.3 (5) and 20 (5) years, respectively. There was a significant correlation between the type of working station before and after the intervention, with the expression of musculoskeletal disorders (P=0.02). There was also a significant relationship between variables of musculoskeletal disorders in the shoulders, necks, waist and hands at different working stations. However, there was a significant relationship between age, work experience and BMI index with musculoskeletal disorders.
Conclusion: According to the results of this survey the best working station is a sitting-and-standing. Therefore, by changing the type of working stations, musculoskeletal discomfort of the employees will be reduced appropriately.

Abstract
Introduction: working with computer for long duration, static condition, and poor posture may lead to musculoskeletal disorders. The aim of this study was to assess an educational and ergonomic intervention on improving work procedure among computer users in office work in 2016.
Materials & Methods: This descriptive-analytic study was carried out on 28 employees of administrative staff of Damghan Velayat Hospital. In order to determine the level of ergonomic risk, the physical status of patients was evaluated before and 6 months after intervention using ROSA method. The ergonomic principles were also used to increase the staff’s awareness. Finally, one-way analysis of variance and independent t-test were used to analyze the statistical data.
Results: Prior to the implementation of the educational intervention program, the most important risk factors were in the neck (P=0.009), elbows (P=0.019) and shoulders (P=0.031), respectively. After the intervention, this level of risk was reduced in the organs, which was a significant change. There were also other variables; age (P=0.028), gender (P=0.015), BMI (P=0.040), education level (P=0.047) and job experience (P=0.025). They had a significant effect on the final score of ROSA.
Conclusion: The results indicated the prevalence of musculoskeletal disorders and ergonomic risk level by ROSA method which requires ergonomic intervention in the design of the environment, tools and equipment along with educational intervention.

Abstract
Background and Aims: Administrative employees are often at risk of developing musculoskeletal disorders due to prolonged computer use. Additionally, frequent interactions with clients expose them to a high mental workload and job stress. This study aims to assess the prevalence of musculoskeletal disorders, mental workload, general health, and job stress among administrative employees, to improve their working conditions.
Materials and Methods: The study is a cross-sectional descriptive-analytical study conducted among the administrative employees of an engineering company in 2021, and finally 119 people participated in the study by census method. Demographic information questionnaires and ROSA, Cornell, NASA-TLX, GHQ, and HSE-UK job stress checklists were used to collect data. Data analysis was performed using SPSS software, employing descriptive statistics, independent t-tests, and one-way analysis of variance (ANOVA).
Results: According to the posture assessment with the ROSA method, the average final ROSA score was 4.33±1.03. Examination of mental load with the NASA-TLX index showed that 78% have a high mental load. According to the GHQ questionnaire, the average final general health score is 24.4 ± 11.73. Also, based on the HSE-UK occupational stress questionnaire, more than 80% (103 people) of employees were under severe stress and 12% (15 people) were under critical stress. A significant relationship was observed between occupational stress, body mass index, and age (p<0.05).
Conclusion: Implementing intervention and control measures to improve musculoskeletal disorders, workload, general health, and job stress is essential.
