Concept of occupational stress and its relations with musculoskeletal disorders has been investigated for years. The present study was performed for determining the role of occupational stress in the development of musculoskeletal disorders (MSDs) among embassy personnel of foreign countries in Iran. Study population in the present cross sectional study was 200 embassy personnel of foreign countries in Tehran capital of the Islamic Republic of Iran. Study questionnaires (Nordic Questionnaire; The occupational stress scale) were distributed into participants and finally 161 questionnaires come back to the researchers (response rate: 80.5%). One week and one year period prevalence of musculoskeletal complaints of included embassy personnel were 59.6% and 75.2% respectively. Mean of occupational stress in embassy personnel with musculoskeletal disorders in recent week and year were significantly higher than embassy personnel without musculoskeletal disorders. Smoking and occupational stress score were independent predictor of musculoskeletal disorders. Occupational stress had an impact on development and persistence of WRMSDs among embassy personnel and next studies in this new field will suggest for more detecting actual causes of WRMSDs in these persons and other office workers.

One-third of globally, injuries to the adults in the world were related to workers and work situations. The aim of the present study was determining of work-related injuries rate among workers at two main metal industries (aluminum and Cooper industries) and independent predictors of fatal work-related injuries among them. Present cross-sectional study was assessed fatal and not fatal work-related injuries among 11172 workers into two groups of Iranian metal industries between April 2003 and September 2011. Information was obtained from the electronic registry of work-related injuries to the health & environment office of Iranian Mines and mining Industries Development and Renovation Organization of the Iranian industrial ministry. Binary logistic regression was used for determining predictors of fatal work-related injuries. During the study period, 55 workers of metal companies had been dyed and mortality rate among study workers was 1.7% and 3282 work-related injuries were reported. Mortality rate in study workers had significant association with injury location (P≤0.00), worker's age (P≤0.00) and not significant association with worker's shift (P≥0.44), educational level (P≥0.46), injury type (P≥0.65) and work experience (P≤0.07). In linear regression model analysis only age of workers was independent mortality predictors among study workers. Based on our findings work-related injuries in mentioned industries in this study setting are high, and a comprehensive injury prevention program seems to be essential.

Cancer is a disease with huge consequences for patients and their families. It has a high mortality rate in both developed and developing countries. Eleven to 15 percent of all cancers can be attributed to occupational risk factors. The aim of this pilot study was to define the risks of specific occupational classes based o n the International Standard for the Classification of Occupations 2008 (ISCO-08) in causing genitourinary (GU) cancer. A matched case-control study was designed and 208 cancer patients were interviewed by a single physician. Controls were selected from cancer patients with different cancers. For assessment of lifestyle, the simple lifestyle indicator questionnaire was. Years of working until 5 years before the diagnosis were questioned and later categorized by the ISCO classification In total 156 GU cases and non-genitourinary cancer patients were selected. The mean age at the time of diagnosis was 51.01 years for both groups. Except the platelet count, there was no significant difference between the groups. Some ISCO classes (1, 2, and 0) were eliminated because of low numbers. The difference between working in different classes of ISCO classification (3 through 9) was not associated with the occurrence of genitourinary cancer. No significant difference was found between the occupational classes in patients with genitourinary cancer and controls.

Musculoskeletal disorders such as low back pain can cause a wide spectrum of chronic complications such as quality of life and general health impairment. Mental health is a wide spectrum of concepts that which those such as anxiety, depression or even quality of life had challengeable impacts on work related characters such as worker productivity, absensism. Present study was performed for evaluation of low back pain prevalence and its association with general health and quality of life status among blue workers of Fars ABFA Company. In the present study we focused on low back pain among 451 blue workers and assessed their mental health status and quality of life status with general health questionnaire (GHQ-28) and short form questionnaire (SF-36) respectively. In comparison one-year prevalence of low back pain was 44.2%. Mean of SF36 (63.90 ± 17.39 vs. 79.42 ± 15.01; P≤0.001) and General health subdomains (58.29 ± 19.63vs. 69.84 ± 18.63; P≤0.001) for workers with low back pain were significantly lower than other workers. Findings of our study showed that low back pain had impact on mental health status and quality of life among workers and these changes must consider in the designing preventive program more than control of pain.
