Background: Productivity plays a fundamental role in the global economy. Human resources are the most important factor, causing an increase or decrease in the productivity of an organization. Ergonomics is the scientific theory that studies the relationship between individuals and other elements of a system and the profession applies theories, principles, evidence, and methods to design to optimize human well-being and productivity of the organization. This study aims to investigate the effects of ergonomic features and anxiety on the productivity of office workers. Methods: In this descriptive-analytical cross-sectional study, 176 office workers (133 female and 43 male) of a university with three years of work experience were randomly selected. Data collection tools included demographic surveys, an inspection checklist, Rapid Upper Limb Assessment (RULA) checklist, the productivity measurement questionnaire, and Beck anxiety inventory. Results: The study results showed that 70% of workstations need to be changed through ergonomic interventions and changes. According to the results obtained from the linear regression model between productivity and working posture, anxiety, and work environmental factors, there is a positive relationship between working environment conditions and productivity (P=0.002). Conclusion: The main contribution of this research is that productivity should receive attention through changing working environment. The chairs are a vital element of an ergonomic and productive work office

Background: Due to the high cost of advanced tractors in developing countries, their use with lower cost and technology has been further considered. Consequently, many of these machines in terms of ergonomics are in poor condition and cause musculoskeletal problems in the drivers. This study aimed to identify harmful postures causing musculoskeletal disorders in the tractor drivers in Iran.Methods: The study was conducted in March 2018 among farmers in Golestan province. The tasks of tractor drivers are divided into three stages consisting of getting on, steering tractor, and getting off. Rapid Entire Body Assessment (REBA) method was used to assess the body postures. In REBA, different postures of the body regions such as the neck, wrist, hands and legs were assessed and finally the level of risk was determined. Then, the levels of ergonomic interventions were suggested based on the risk level. Results: Based on the REBA analysis, most of the tasks performed by the tractor drivers had medium risk and they need prompt investigation and change. For the task of getting on and getting off the tractor, the highest scores were assigned to the arms, legs and trunk. For the task of steering tractor, the highest postural scores were related to the wrists, trunk and legs.Conclusion: Ergonomic and posture conditions of Iranian tractors are not suitable. Therefore, it is necessary to implement ergonomic interventions to reduce the risk of developing musculoskeletal disorders.
