| Introduction|| |
Physical health plays an important role in the individual and social life and lack of attention to this important factor leads to decrease in performance, loss of manpower and psycho-physical complications, especially in professional services. 
It is important to pay attention to the physical and mental aspects of health in all spheres of life, including ones work life. Work factors are extensively associated with the health of employed people and the international work organization reports that one out of three employees have a conflict between his work and family environment. 
According to WHO (World Health Organization) statistics, 3 million workers in the world lose their lives every year due to various diseases and work accidents. In Iran, this problem is remarkable. In the national study of health and disease in Iran using the General Health Questionnaire GHQ-28, the rate of disorders in the population older than 15 years was reported to be 12%. 
There is no doubt about the effects of professional health on the psychological and physical health of workers that is confirmed by various researches. As mining work conditions are severe, this topic gains more significance. Furthermore, the small and dark surroundings, long distance between mines and cities and lack of communication facilities makes mining work conditions severe and health threatening.  According to the results of a study in one of the Iranian mines, 25% of mine workers do not have appropriate physical health conditions. 
Studies show that psycho-physical factors affect day to day work and can impose economical losses on society. It affects the implementation, progress or continuation of a process or work and even results in work accidents. 
A study on workers of the Medical Treatment and Education Center showed that only 5.7% of the workers had physical health problems.  However, literature review shows a significant relationship ( P < 0.05) between physical health status and accidents. ,
Considering the above mentioned points, mine workers are one of the most vulnerable workers in mining and industrial sectors.
The aim of the present study was the evaluation of the physical state of the workers of the Central Iron Ore Company of Iran along with its relation to type of job, education level, cigarette smoking and history of work accidents.
| Materials and Methods|| |
This was a descriptive, cross-sectional study that included 388 mine workers in the Central Iron Ore Company of Iran. The samples were selected randomly out of 2100 mine workers. Research tool was a two part GHQ questionnaire. The first section of the questionnaire was related to the demographic characteristics of the workers and included age, type of job, work experience, marital status, cigarette smoking, job satisfaction level, consent of the employer, work shift, income level satisfaction and work accidents.
The reliability and validity of both sections of the questionnaire were determined by specialists (Cronbach's alpha coefficient was 0.83). 
The questionnaire evaluated the physical symptoms of the individual in the past month. As most of the workers had low education levels, the questionnaire was filled by the assistance of researcher. Simple Likert scale was used for scoring and each answer was scored between 0 and 3.
SPSS (Statistical Package for Social Science) program was used for analysis and statistical tests included variance analysis and Pearson correlation tests. Individuals with a total score of less than 7 were considered ideal, 7-14 average and those with scores above 14 as a bad physical condition.
| Results|| |
The present study was performed on 388 workers of the Central Iron Ore Company of Iran, out of which 10.6% were single and 89.4% married. Other statistics were as follows: 22.9% smokers, 77.1% non-smokers, 13.9% were highly satisfied with their work, 42.3% satisfied, 34.8% relatively satisfied, 9% not satisfied, 30.4% morning shift workers, 1.3% night shift, 65.2% rotational shift workers, and 2.3% morning and evening shift workers.

| Discussion|| |
This study showed that 18% of the population under study had some kind of physical health problems. The results of another study indicates that 26.7% of the women workers complained of physical health problems.  The difference could be due to the fact the study sample included women in that study, while the mining workers in the present study were men and the results of various studies show that women workers suffer from relatively more problems because of their natural physical restrictions.  A study showed that work burnout in men is more than women that is confirmed by the other studies. ,
The results of the present study showed that physical health problems in mine workers are more than other occupations because of work conditions and high levels of fatigue in this company  and are in line with the results of the Wessely study. 
In a study, it was determined that there is a significant relationship between parent's occupation and general physical health of students. It was concluded that low-income and hard work job employees cannot afford to meet welfare needs of the family as compared to higher-income jobs, thus this issue leads to psychological and physical problems of the workers family member.  This is in line with the results of the North American study wherein psychological and physical problems in the Canadian population with higher standards of living are comparatively less. 
Khaghanizadeh states that there is no relationship between the economy and livelihood situation and their physical factors,  but the study concludes that there is a significant relationship between type of job and burnout with physical and psychological health.  The result of the study by Danesh is also in line with our results. 
The results of the present study showed there is a significant relationship between cigarette smoking and physical health that is in agreement with the results of the study by Suda that states lifestyle including cigarette smoking and alcohol consumption has a significant effect on physical health.  The study by Corti and coworkers concluded that the health of smokers is in more serious condition as compared to non-smokers and there is a significant statistical relationship between cigarette smoking and physical health.  Another study states that high stress works leads to cigarette and alcohol abuse thus deteriorating physical health and leading to physical damage. It concludes that cigarette smoking is related to physical complications. ,
The results of the present study showed that there is a relationship between history of work accidents and physical health. As stated earlier, the physical and psychological health of mine workers is at a greater risk as compared to other workers due to a number of reasons, the most important being in high-stress conditions, workload, organizational and individual factors. Physical problems like pain and fatigue lead to increase in work accidents. , Considering the high levels of stress, physical and psychological disorders in mining work as compared to the general population, , work burnout, especially in younger and inexperienced workers  and strong relation between physical health and history of work accidents. It seems there is a need for higher level occupational health and work authorities of the Yazd, Bafgh district and managers of the Central Iron Ore Company of Iran to pay special attention to both pre-recruitment and regular physical examinations of workers in order to prevent or remove the present problems of workers and increase their physical, mental and social health levels.
