We performed a cross sectional study with the aim of assessing levels of habitual physical activity and associated factors (barriers and motivators), finding the stage of change among high school girls, and exploring relationships between physical activity and the following set of factors: age, parent education, type of school attended, knowledge, and attitude. 457 girls in the 1SI to 3rd grade of high school with a mean age of 15.6 (%95.3 cases were 14th to below 17Ih years old) in Tehran&aposs second region of educational office district were selected via proportional-to-size and cluster sampling methods. These girls attended 4 different types of facilities (public and private high schools / public and private vocational schools). The data were gathered through self-administered questionnaires. Our results indicated that %58.6 of students were in pre-contemplation and contemplation stages, while 24.7% were in action and maintenance stages of change.
The mean level of physical activity at work (in school) was 2.22, which was significantly lower than 2.75- the minimum acceptable level of physical activity at work (p<0.00 ). The mean level of sport activity was 2.73, significantly (p<0.001) higher than 2.33 (minimum acceptable level of sport activity). The mean level of physical activity at leisure time was 2.50, which had no significant difference with the minimum acceptable level of 2.50. (Note: all max. acceptable level is 5).
The most important barriers identified were: time constraints, lack of companions, lack of suitably located facilities and a general state of lassitude.
The most important motivators were individual interest, desire to lose weight, company of friends, and support of parents. The level of exercise did not show a significant relationship with age, probably because of the limited range of age categories enrolled in this study. Levels of physical activity at work and sport activity (p=0.004 for ph.act.work and p=0.012 for sport) showed a significant positive relationship with the mother&aposs level of education. No significant relationships were found between any type of physical activity and the father&aposs education. The level of sport activity in private high schools was significantly (p=0.005) higher than in public high schools. On the other hand no significant differences were observed between levels of physical activity in private or public high schools compared to private or public vocational schools. Only sport activity had a significant positive relationship with higher knowledge (p=0.005) and attitude (pO.OOl).
The majority of our population (%58.6) was in pre-cont. and cont. level of stage of change. Therefore more emphasis should be placed on improving health education. We must also teach our teenagers to organize their leisure time so they can do some simple and inexpensive physical activities like brisk walking between home and school or while shopping.

Background and Aim: Domestic violence against women is a major public health problem throughout the world. Feelings of shame, guilt and fear on the part of women, together with an unresponsive health care system continue to silence and isolate women who suffer abuse and negligence- with major effects on their physical and mental health. Mental health consequences include depression, anxiety, stress disorders, and somatization. This study estimates the prevalence of domestic violence and its associated effects on the victims' mental health.
Materials and Methods: This cross-sectional study used data from 1189 married women over the age of 15, selected randomly among the residents of Tehran.
Results: The overall prevalence of domestic violence was 35.7%. Thirty percent of the subjects had experienced physical violence, 29% suffered mental violence and 10% had been victims of sexual violence many of these women had suffered all the three types. The most frequent types of physical violence included beating in the form of kicks, punches, and slaps (91%) common types of mental abuse included humiliation, verbal abuse and insults (93%), and threats of violence (83%). Data on mental health status indicate that overall, as many as 34.1% of women could be suffering from disorders such as depression and anxiety. The risk of psychiatric disease was 3.5 times higher in victims of violence compared to other women (OR = 3.5, CI 95% = 2.72 - 4.58). Major factors contributing to domestic violence were husband addiction, low economic status, and the number of children (P<0.001). These results are consistent with the current literature on domestic violence and illustrate the high prevalence of this phenomenon. Victims are commonly depressed and have a higher rate of anxiety.
Conclusion: Violence is an important indicator of women’s health. Screening programs for domestic violence could be effective, along with community support and referral to health care and legal facilities. It is also crucial to promote knowledge and awareness of violence among health care providers. This study shows that a community-wide effort to establish links between health care settings and community services may be important in addressing the needs of victims.

Background and Aim: Cigarette smoking is a global problem, but is decreasing in most developed countries. Reports from the East Mediterranean show that unlike the 5 other WHO regions, cigarette smoking has not decreased in this particular zone. There is a vital need to address the problem, especially in the adolescent population. This qualitative study looks at the motives behind the smoking tendency in boys aged 13-15.

Materials and Methods: The study consisted of 6 focus group discussions performed in Tehran orientation (intermediate) schools participants were male students aged 13 to 15 years. Purposeful sampling was used to draw in participants who were willing and able to take part in the group discussions. Each group was composed of 6-8 students, whose voices were recorded to determine themes and subthemes.

Results: Family and social factors have a more prominent role in creating the smoking tendency compared to individual factors. The most important elements are family history of smoking, having friends who smoke, poor parental control, conflicts at home, divorced parents, failure to consult with parents, easy availability and relative cheapness of cigarettes, and lack of information.

Conclusion: Serious attention must be paid to the social and family factors in the initiation of the smoking habit. Social and political institutions must come up with effective programs to control the social and family factors that have a role in creating the smoking tendency.

Background and Aim: Pressure ulcer is a common problem and a large drain on hospital resources, especially in wards such as ICU where patients stay for a long time. The aim of this study was to explore the likely factors contributing to pressure ulcers in the ICU units of Tehran University of Medical Sciences teaching hospitals, Tehran, Iran.

Materials and Methods: This project was conducted in all the seven ICUs of four teaching hospitals affiliated to Tehran University of Medical Sciences. In the first phase the researcher performed a direct observation of all the 90 patients who were admitted to the ICU units to check the presence of any pressure ulcer. In the second phase, 310 patients discharged from the same ICU units between March 2007 and February 2008 was randomly selected and their medical records reviewed. A structured questionnaire was used to collect the data.

Results: Pressure ulcer occurred more frequently in the elderly women patients who were less active and had less mobility, hospitalized for a long time, or those with fever, diabetes, high blood pressure, paralysis, or respiratory diseases. In addition, pressure ulcer was seen more frequently in the patients hospitalized in the general ICUs, as well as in those with infections and different types of tumors.

Conclusion: Using a standard risk assessment tool and paying attention to the main risk factors of pressure ulcer can be a useful method for identifying the high-risk patients before admission in order to prevent them from developing such ulcers.

Background and Aim: Considering the acute and chronic effects of organic solvents to which vehicle painters are exposed for long periods of time, their evaluation and control is crucial for protection of health of the employees. This study aimed to find the most influential factors on exposure to, and spreading pollution with, benzene, toluene, xylem, and etylebenzene (BTEX) in order to be able to choose the best control measures.
Materials and Methods: In a motor-vehicle company the vehicle painting process was studied in detail and the solvents used in paints and in spreading organic solvent stations were identified. Based on the types and concentrations of the variables being studied, using the NIOSH method a total of 240 air samples were collected (5 samples for each variable and the respective controls) and analyzed. The SPSS version 11.5 was used for data analysis, the statistical tests being multi-regression and analysis of variance.
Results: Exposure to benzene in all occupational tasks, as well as to toluene in top coating and undercoating stations exceeded, while exposure to etylebenzene and xylene did not reach, the respective permitted exposure limits (p<0.05). The most effective factors on exposure to all the four solvents were, in order of effectiveness, occupational task, gun type, and the type of paint sued (p<0.05).
Conclusion: The effects of the variables studies – occupational task, gun and paint types – on exposure to BTEX relate to differences in occupational task work load, the type of gun used, and the paint organic solvent formulation. The reason for the potentially high exposure to benzene is its presence as an impurity in the paint solvents. Thus, it is highly recommended that in the process of control and evaluation special attention be paid to these factors.

Background and Aim: Coronary artery disease (CAD) and its complications at a low age are more serious and more progressive than at higher age. Because of this difference in the natural history of the disease as a function of age, this study was conducted to compare CAD risk factors between two age groups, namely people below and above 45 years old.

Materials and Methods: Two groups of 200 hospitalized CAD patients each, one below, and one above, 45 years old were selected by simple random sampling between 2005 and 2007. Two groups were similar with regard to dates and duration of hospitalization. The following data were collected from the patients' hospital files and analyzed using SPSS/Win: age, sex and marital status area of residence a history of smoking, diabetes, and hypertension a family history of early-onset cardiovascular disease (CVD) weight and height and lipid profile. The logistic regression test was used to compare the variables between the two groups.

Results: The following variables were found to be positively associated with CAD in the under-45 year group: smoking history (OR=2.54 p=0.009), a history of early-onset CVD (OR=3.15 p=0.009), low high- density lipoprotein cholesterol (HDLc) (OR=5.53 p<0.001), and high blood cholesterol (OR=3.96 p<0.006).

Conclusion: The most important coronary heart disease risk factors at a lower age are smoking, a history of early-onset CVD, low blood HDLc, and high total blood cholesterol.

Background and Aim: Due to the design features, facilities and the presence of crude oil materials or refined products from crude oil, the refining industry is prone to major accidents such as fire and explosions, which cause a lot of damages and losses. On the other hand, due to the development of intelligent technologies and drones (remote-controlled birds) and the widespread use of these technologies in various industries, the use of these new technologies in the oil and gas industry is inevitable. This case study was conducted with the aim of utilizing drone technology in fire crisis management in oil refineries in the Lavan Oil Refinery, Iran.
Materials and Methods: Data were collected using qualitative methods and literature review by combining keywords such as refinery, fire and explosion and drone, as well as holding semi-structured interviews with 15 informed and experienced persons from among refinery personnel. In order to identify internal strengths (S) and weaknesses (W) and external opportunities (O) and threats (T) the gathered data were analyzed using the basic SWOT model.
Results: Analysis of the data show the following strategies to be the results of the external threats and opportunities and internal strengths and weaknesses: Strength/Opportunity (SO), Strength/Threat (ST), Weakness / Opportunity (WO) and Weakness/Threat (WT).
Conclusion: The use of drones for monitoring (finding the location and source of fire), identifying (determining the exact location and extent of the fire), confronting and controlling (relief and rescuing, saving the lives of firefighters, firefighting) in the Iranian oil industry requires making changes in the capacity and levels of technology and the equipment and manpower.  Making these changes requires the support of managers and personnel of the oil industry in order to use this new technology and make it operational. In this way, fire crisis management in refineries can be implemented by using drone technology.
