Incidence of musculoskeletal disorders is one of the effects of inappropriateness between subjects and technology, which reduces the level of human immunity, occurrence of occupational disabilities, loss of working time and increasing costs. The aim of this study was to evaluate risk factors of musculoskeletal disorders for assemblers in an electric industry workerand effect of interventions on reducing the level of these disorders.

This interventional study was carried out among 75 women workers in a wall plug factory having more than one year working experience in 2017. The data collected were analyzed by using SPSS software version 20 and Chi-square, regression, independent t-test, after reviewing medical documentation and completing QEC and Nordic questionnaires before and after ergonomic interventions which was done in the form of training and corrective actions.

According to the results, the highest reported musculoskeletal disorders were in the shoulder, wrist, lower waist, upper lobe with frequency of 68%, 61%, 58% and 51%, respectively, that with respect   to ergonomic interventions, this reduction for each area was 60%, 46%, 49% and 46%, respectively, which was relatively a good reduction in abnormalities.

The interventions in this industry have shown the effectiveness of these methods for reducing musculoskeletal disorders, and it can be concluded that educational interventions and making activities periodically together have been effective in reducing disorders.

Some of people prefer daily activities; others, nightly ones. Studies have shown that performance levels may be affected by circadian rhythms. The high mental workload occurs when the task is greater than the capacity of the operator. Regarding the probable relationship between circadian types and mental workload, we decided to evaluate this factor in the assembly workers of a manufacturing company.

The study was a descriptive -analytic and cross-sectional one being carried out among 120 female assembly workers of manufacturing company. In order to evaluate of circadian types and mental work load, Iranian version of MEQ (Moring- Evening Questionnaire) and NASA-TLX (NASA-Task Load Index) have respectively been used. Data analysis was carried out by using SPSS 20. It is noteworthy to mention that P value

Upper limbs are more susceptible to musculoskeletal disorders. The OCRA method is suggested to measure the biomechanical risk of the associated with the manual, repetitive work in upper limbs. Questionnaires can be used to measure the symptoms of diseases and disabilities. The DASH questionnaire is one of these questionnaires that are used to evaluate disability of upper limbs. In this study attempted to evaluate the biomechanical risk factor and relationship with disability of the upper limbs in assembly workers.

The study was a descriptive – analytic and cross-sectional one being and was carried out among 120 female assembly workers. For the measurement of biomechanical risk factor and disability of the upper limbs have been used The OCRA method and Iranian version of DASH, respectively. Data analysis was carried out by using SPSS 20. It is noteworthy to mention that P value <0.05 was considered significant.

in this study, assembly workers were in terms of risk factors of biomechanics and upper limb disability in low risk and low disability, respectively. Also, the relationship between biomechanical risk factor and disability of upper limbs, was significant and direct (P value <0.05).

Since the relationship between biomechanical risk factor and disability of upper limbs, was significant and direct, it can be concluded that musculoskeletal disorders due to inappropriate working conditions can lead to motor limitation and upper limb disability at different levels.

Unsafe behaviours are one of the important factors in occurrence of occupational accidents that can have a negative effect on the safety attitude. Individuals with type a behavioural pattern, with personality traits, such as being hasty, competitiveness, hostility, and aggression, can be effective in the incident of occupational accidents in the workplace. This study aimed to investigate the relationship between occupational accidents and behaviour patterns among workers.
This descriptive-analytic study was conducted among 60 workers engaged in one of the motorcycle assembly lines in Tehran in 2017. Friedman and Rosenman behavioural patterns questionnaire was used to determine the behaviour pattern. Moreover, the incident of accidents and pseudo- accidents recorded in the Health and Safety Department were investigated. Data analysis was performed using SPSS22.
A significant relationship was found between type A and B behaviour pattern with incident of accidents and pseudo- accidents. The chance of incident of accidents and pseudo- accidents among workers with type a behavioural pattern were 4.85 and 4.65 times more than that of type B behaviour pattern, respectively. There was a significant and positive statistical correlation between the behaviour pattern score and the frequency of accidents and pseudo- accidents.
Workers with type a behavioural pattern are more likely to be injured due to their dangerous behaviours. Therefore, one of the solutions to improve safety hazardous behaviours and preventing accidents and pseudo- accidents in workplaces is to select individuals with lower risk behaviors, especially for high-risk activities.

Work related musculo-skeletal disorders are major problems in most of industries which can affect production rate and impose direct and indirect costs. The aim of the present study was to assess risk factors causing sick leave in a car manufacturing. In this cross sectional study, a total of 234 assembly workers were included. Data were recorded using the ergonomics risk assessment checklists and personal information questionnaires. Statistical analsyis was performed using SPSS ver.16 software and chi-square, Mann–Whitney and Kruskal–Wallis tests were used. The reults showed that the Mean (±SD) of worker’s sick leave in one year prior to the study was 7.5 (±9.5) days. Low back pain was the most prevalent cause of workers’s seak leave. No significant association was found between sick leave and some factors including body posture, manual material handling tasks, and force and power grip. Among the personal factors, age and smoking habits were singnicantly associated with sick leave (p<0.05). This study emphasized that more attention should be paid on ergonomic proplems among assembley workers and ergonomic interventions such as work stations redesign should be considered.

the Car manufacturing workers due to direct exposure to machinery and wide range of ergonomic problems have high prevalence of musculoskeletal disorders rather than other industries workers. The purpose of this study was to investigate relation between pains with sick leave in an Iranian car manufacturing company. This case-control study was conducted at assembly plant Irankhodro Car Company. In this study 528 workers (234 case group and 294 control group) were randomly selected. Data were collected by body map and personal information questionnaire. Statistical analyses such as Mann–Whitney and χ2 test have been used for data analysis. results shown that there was no significant relationship between sick leave and pain in bodies (p<0.05). There was significant relationship between Low back pain and sick leave (p<0.001). In case group, the maximum and minimum pain relate to leg and left knee (94%) and elbow and Right forearm (3.2%) respectively. also there was maximum pain intensity in back (63.95±15.78) and minimum pain intensity in elbow and left forearm (44.88±15.55). based on this study effecting factor on sick leave requires ergonomic considerations. Also preventive and modifying actions is essential for the improvement of the ergonomic working conditions of assembly workers and their lifestyle.
