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.

Some factors such as stooping posture and frequent kneeling in miners can increase prevalence of their musculoskeletal disorders Present study was performed for assessment of MSDs prevalence among Iranian coal miners and finds its relationships with some their characters including age, work experience and body mass index.
Participants in the persent cross sectional study, were 505 coal miners which selected among Iranian coal miners by simple random method. Data of musculoskeletal disorders (MSDs) gathered by Standardized Nordic self-reporting questionnaire. Demographic and work related data were collected into the check list.
Findings of persent study showed that 56.1% and 66.5% of study miners claimed one of the MSDs complaints during last week and in the last year respectively. Lumbar, Knee(s) and Back had most common MSDs prevalence at last week and year. MSDs prevalence had significant association with age (P≤0.02) and non-significant association with BMI (P≥0.8) of workers.
MSDs in Iranian coal miners were happened in high rate. Ergonomic interventions strategies in the workplaces must be focussed for elimination of environmental hazards such as apposition at the time of work, manual handling of heavy loads.

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.

Work related musculoskeletal disorders (WMSDs) are considered as the main cause of occupational complications and disability in developing countries. In Iranian steel companies, workers commonly are directly involved in the production process and physical activities such as manual material handling and awkward postures. Present study was performed for assessment of neck and back pain prevalence among workers of four Iranian steel industries.
Study participants in our cross sectional study, were randomly selected from workers of four Iranian steel industries. Data of neck and back pain were gathered by Nordic questionnaire. Logistic regression was used for controlling confounding variables and determining independent predictors of neck and back pain among study workers.
Among study workers, prevalence of neck and back pain in a recent year were 18.40% and 13.90% respectively. Age (p≤0.02) and job experience (p≤0.00) had significant association with neck pain. Age, sex, BMI, and job duration were not known as an independent predictor of neck or back pain.
Neck and back pain prevalence in steel industries were happened whit higher rate compared to most of other countries. Next studies will suggest for determining work related risk factors of WMSDs in workers and designing preventive strategies.

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 on 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.

Farming as job, had some activities or work task such as strenuous physical tasks and high levels of manual labor in farming job, which can increase risk of MSDs among farmers. Present study with prospective design designed for assessment role of rice farming in developmental risk of MSDs among Iranian rice farmers.
Present prospective study was performed on 75 rice farmers of Babol city in Iran and 75 participants without history of rice farming, during March 2013 until September 2013. At the beginning of the study, participants did not have any musculoskeletal complaints in each of their body parts. Study exposure in the present study was working in the rice farming workplace for one rice farming period which at least lasted for four months. Frequency of MSDs had been assessed by Nordic questionnaire at three follow-up points.
We followed 75 rice farmers of Babol city as expose and compare them with 75 participants without history of rice farming. Within the six months follow-up, MSDs complaints in 38 (50.66%), 61 (81.33%) and 47 (63.51%) rice farmers had been reported respectively in upper limbs, spinal and lower limbs regions.
In the present study, rice farming was reported as a risk factor for MSDs in the spinal region and lower limbs.

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.
