Background & Objectives: As a result of an increase in using of computers in the occupational environments, the prevalence of musculoskeletal disorders (MSDs) has increased in these types of occupations. These musculoskeletal disorders also Imposes heavy financial consequences on health care systems. The aim of the present study is to evaluate the relationship between psychosocial factors and the prevalence of musculoskeletal discomfort in VDT workers. Methods: This cross-sectional study was carried out in three cities covered by one directs of the Iranian Gas Transmission Operation during 2011 and 2012 years. In this study, all of 300 office workers in this region participated. The investigation consisted of two questionnaires, first standardized Nordic questionnaires to measure the prevalence of disorder, second ALL EMPLOEE SURVEY questionnaire to measure psychosocial factors. Statistical analyses were performed by the Statistical Package for the Social Sciences software (SPSS version 16.0). The Statistical methods used in this study include chi-square and logistic regression. Results: The mean age and work experience of the subjects were 7.00 ± 59.34 and 71.6 ± 56.9, respectively. The highest prevalence rate of disorder was found in the Lower back (49.7%) and neck (49.0%) regions. Results of the multiple logistic regression models show that psychosocial like work / family balance, job control, leadership, resources , customer service , co-worker support , reward , cooperation, employee development and job demands, and the individual factors like sex, BMI and education level were independently associated with prevalence of musculoskeletal disorders (p<0.5). Conclusion: The results of the study indicated that some psychosocial factors are related to prevalence of musculoskeletal disorders. Consequently, in order to prevent or reduce musculoskeletal disorders, these factors must be considered.

Background and purpose: The Upper Limb Disorders (ULDs) are the most prevalent types of occupational injuries, which appear following long exposure to ergonomics factors with specific repetition. The present study was aimed at assessing the upper limb disorders among assembly lines workers using Health and Safety Executive (HSE) method and and also evaluating it's correlation with sense of pain in gas control company of Iran.
Material and Methods: This cross sectional analytical study was carried out on 40 assembly workers. In order to evaluate the ULDs, study was began by using Risk Factor and accurate assessment HSE questionnaires, then thequantitative indicator Body Map was used for measuring workers pain sense. The collected data was analyzed by SPSS16.
Results: The measured quantities of risk factor of repetition, working postures arm and shoulder, head and neck and fingers, hand and wrist were 92.5%, 72.5%, 50.0% and 45.0% respectively. Work history and gender were significantly related with most disorders (P-Value= 0.022 and 0.001 respectively). The best correlation coefficient was between postures arm and shoulder, postures hand and wrist, repetition with hand and shoulder pain level(R= 0.62, 0.67, 0.74 and 0.72 respectively).
Conclusion: Prevalence of the ULDs among assembly workers was high. Considering the low age and work history level of workers, an increase in ULDs signs intensity is predicted in the not too distant future.
