Abstract
Background & Objectives: The rate of suicide varies amongst different parts of Iran. Since there is little knowledge about the risk factors for suicide attempts we carried out this study to determine the status of psychiatric disorders and risk factors of repeated attempted suicide in suicide attempters whom admitted to poisoning emergency in Isfahan, Iran.
Methods: Patients with having attempt to suicide, admitted to emergency ward in Khorshid Hospital in Isfahan and were interviewed by a trained psychiatrist during 2009 year. Interview was based on DSM-IV.
Results: Participants consisted of 703 individuals (424 of them were female) with mean age of 25.9±9.7. One hundred twenty five (125) had positive family history of suicide attempt, 501 people were first time suicide attempters, 106 second, 58 third, and the others were forth time or more suicide attempters. Bipolar spectrum disorders, unipolar depression and adjustment disorders were the more frequents psychiatric disorders respectively. Age, family history of suicide, kind of diagnosed psychiatric disorder and method of attempted suicide were meaningfully related to mean of attempt suicide frequency.
Conclusion: Bipolar spectrum disorders, especially recurrent depressive episodes is the major risk of repeated suicide attempt and co-morbidity of another psychiatric disorders increase highly the risk of suicide reattempt.

Abstract
Background & Objectives: In the chain of vehicles, human and environment, the human factors are the most complex element in the causes of road traffic injuries (RTIs). Unauthorized speeding and overtaking are considered as the main human factors resulting RTIs. This study estimated the population attributablefraction of two human factors, the most common risk factors of rural roads, of RTIs.
Methods: To calculate the population attributable risk, the prevalence of unauthorized speeding and overtaking registered in Police data was employed. Effect size related to odds ratio was employed using Logistic regression. Joint effect of related risk factors also calculated and reported. Dasta were taken from national traffic police using the KAM 114 froms.
Results: The percentage of population attributable risk of unauthorized speeding for deaths at crash scene was 20.9 and for injured cases was 16.6. These values were 13.5 and 13.4 for unauthorized overtaking respectively. Corresponding for joint effects the population attributable risk was 31.6 for deaths and 27.8 for injuries.
Conclusion: The results illustrate the importance of speed control and unauthorized overtaking as a priority of RTIs in Iran. It is recommended that related laws and legislations should be pursued more seriously, and followed by more effectively.

Abstract
Background and Objectives: The purpose of this study was to assess the reliability and validity of Persian version of survey instrument for Behavioral Risk Factor Surveillance System (BRFS).
Methods: Content and Face validity of Behavioral Risk Factor Surveillance System (BRFS) questionnaire were examined with Backward-Forward method. This method consisted of four steps: translation, back-translation, expert review and Pilot study. For evaluation of reliability of questionnaire, 194 adults of 18 years or older from Karaj province were interviewed. For the examination of reliability, Cronbach’s alpha was calculated to assess the internal consistency of the questionnaire. The reliability of quantitative variables evaluated with intra class correlation (ICC) ordinal variables with weighted Kappa and nominal variables with Kappa and weighted Kappa were calculated as well.
Results: Average age of participants were 38.8 15. Majority of participants (66.5%) were in 18-44 years group, 26.8% in 45-64 years and others 65 years and older. In validity procedure, 26 questions were deleted, 3 questions added and 6 questions were modified. Questions of ‘having situations of HIV morbidity’ and ‘Do you currently use drug abuse’ were least reliability and deleted from questionnaire. Others were reliable. (It might be better to say how many questions remained finally)
Conclusion: Our results indicate that BRFSS Persian version questionnaire has acceptable reliability and criterion validity for surveillance system in Iran.

Abstract
Background & Objectives: Sterpococcosis/lactococcosis is an economically important zoonotic disease in aquaculture industry particularly in farmed rainbow trout. The annual loss due to the disease is tens millions US dollars. This descriptive study was aimed to identify the regional distribution of these economically important bacterial diseases in 50 farmed trout in Charmahal-va-Bakhteyari (25 fish farms) and Kohgiloyeh-va-Boyerahmad (25 fish farms) provinces plus detection of the relative prevalence of the presence of 20 risk factors.
Methods: Each trout farm was clinically inspected to identify the risk factors, followed by sampling of the clinically affected fish for bacteriological and molecular studies.
Results: The results showed that form 25 fish farms examined in Charmah-va-Bakhteyari, 56.% (13 fish farms) were affected with Lactococcus garvieae and 20%(5 fish farms) were affected with Streptococcus iniae, while these were 64% (16 fish farms) and 12% (3fish farms) in Kohgiloyeh-va-Boyerahmad, respectively. The relative prevalences of the presence of 10 and 16 risk factors were above 80% and 50% in the trout farms of both provinces.
Conclusion: These results clearly demonstrated that occurrence of streptococcosis and lactococcosis in farmed trout has a wide regional distribution in trout farms of these provinces and the presence of risk factors are remarkable in the examined fish farms.

Abstract
Background & Objectives: Although the population of elderly is increasing in Iran, few studies carried out on this group. The aim of this study was to identify life expectancy and contributory risk factors for the Tehranian elderly of ages above 60 years.
Methods: Individuals above 60 years old whom were recruited in the primary phase of the Tehran Lipid and Glucose Study (TLGS) during 1998-2001 were followed up for 12 years and their vital status were registered (1998-2011). Age and sex mortality rates for age groups (60-69, 70-79, 80+) were calculated and by using Cox proportional hazard model the mean of survival time and hazard rates with respect to risk factors were estimated.
Results: Life expectancy for females and males after crossing 60 years of age reaches to 81 and 80 years, respectively without any statistically significant differences between these two groups. Cox model showed that diabetes, BMI>33Kg/m2 and non ischmecic heart disease reduced survival time in women significantly. While diabetes, smoking, hypertension, ischemic heart disease, history of MI, stroke or sudden death of father, brother or son, lack of physical activity and antihypertensive medications are among the hazardous risk factors for men.
Conclusion: Among the variables studied, only three (ABC) of them were found as risk factors of women's life, while for men seven risk factors were identified. It seems that more studies are needed to determine the risk factors for women.

Abstract
Background & Objectives: Randomized controlled trials are the most reliable type of study to be able to compare different interventions in scientific research. The introduction of bias into the design and conduct of randomized controlled trials can seriously affect the accuracy of the results and led to the results be invalid. The aim of this study was to assess the bias in randomized controlled trials published in Iranian nursing and midwifery journals.
Methods: We searched all published articles in eight professional nursing and midwifery Iranian journals in 2010. Risk of bias in RCTs was assessed using of Cochrane group risk of bias standard tool by two reviewers independently.
Results: After reviewing the eight journals, 68 randomized controlled trials were retrieved. The majority of studies had unclear or high risk of bias. Random sequence generation in 22%, concealment allocation in 4.5%, blinding in 22%, incomplete outcome data in the 35.3%, selective outcome reporting in 51.5%, and other bias in 36.7% of the studies were in low risk of bias.
Conclusion: A large proportion of the studies had high or unclear risk of bias. It was considerable that none reporting bias led to uncertainty reader from study quality. Bias might significantly affect the internal validity of the studies results therefore in interpretation of the findings of these studies caution should be taken.

Abstract
Background & Objectives : World Health Organization has recommended the main strategies for the prevention of road traffic injuries on some of the risk factors. This study aimed to prioritize the preventive interventions according to risk factors of road traffic injuries in Iran.
Methods: The potential impact fraction (PIF) of the main strategies for prevention was analyzed from national traffic police data registry in 2011 in urban and rural roads. PIF was calculated for risk factors of road traffic injuries and joint effect at three counterfactual distributions: theoretical minimum risk level, plausible minimum risk level, and feasible minimum risk level. The priority setting of preventive intervention was performed based on contribution of each risk factor.
Results : Based on the potential impact fraction of death (PIF calculated using odds ratio of death) the priorities were as follows in order: wearing a helmet by the motorcycle passenger, wearing a helmet by motorcycle rider, and lack of speed management. Risk factors in this study were more important in urban roads and joint effects of risk factors were close to 100 percent
Conclusion: It is strongly recommended that future interventions focus on the use of the helmet by motorcycle passengers and riders, the use of the seat belt by the passengers, and speed management. Our findings indicated that laws and legislations should be pursued more seriously. Calculation of the potential impact fraction is better than the population attributable fraction and allows for more accurate prediction of the future.

Abstract
Background and Objectives: Nowadays 60% of deaths and 47% of diseases load worldwide caused by chronic diseases. Considering the different results of the conducted studies, the current study was performed to review the effect of life style educational intervention on improving cardiovascular risk factors.
Methods: In this review, English and Persian databases were investigated. All types of studies were included. There was no time limit. The articles in any other languages but English (except for Persian), and also abstracts presented in international congresses and meetings were excluded. Other studies were included if they had an acceptable JADAD score.
Results: During the primary search, 194 articles were found which through investigations 43 articles were finally included. The articles were published from 1989 to 2013. There were 3 domestic papers. Only two articles (4.65%) did not show any improvement in the risk factors while the others suggested significant improvements in the risk factors following educational intervention.
Conclusion: Considering the general findings of the reviewed articles, it seems that the majority of the articles confirmed the effect of lifestyle education on cardiovascular risk factors- blood cholesterol, systolic and diastolic blood pressure, and cigarette smoking along with knowledge and attitude in high risk patients. The finding shows the necessity of “lifestyle” educational intervention in patients at risk for cardiovascular events.

Abstract
Background & Objectives: Keeping various species of reptiles as pets has become popular in Iran alongside other parts of the world. On the other hand, Salmonellosis is one of the most important zoonotic diseases and reptiles have been known as reservoirs of Salmonella. Therefore, this study was designed to assess Salmonella infection in reptile pets of Tehran.
Methods: Fecal samples were collected and cultured for Salmonella isolation from 270 reptiles referred to the specialized veterinary clinics in Tehran. Statistical analysis was conducted on the data.
Results: Salmonella was cultivated from 142 samples (52.6%). Salmonella isolates belonged to a variety of serogroups however, more than half of them belonged to serogroups B and C. Most tested reptiles were healthy and most owners were unaware of the risk of Salmonella. Possible contact of these animals with immune-compromised people was recorded in many cases.
Conclusion: The results of this study revealed that considering the fact that reptile pets are becoming more popular in Iran, educating reptile owners who are mostly unaware of the reptile’s safe keeping methods is a necessity. Finally, more studies are suggested to further investigate the role of reptiles in the epidemiology of human salmonellosis in Iran.

Abstract
Background & Objectives : Health risk behaviors in adolescence, such as alcohol consumption and smoking, can affect both short-term and long-term health. The aim of study was to estimate the prevalence of health risk behaviors among high school students of Qazvin.
Methods : The target population of this descriptive study was all high school students of Qazvin who were enrolled in the 1390-91 academic year. The sample group included 160) 239 girls, 271 boys) students that were selected by randomly multistage sampling. The assessment instrument was the Youth Risk Behaviors Surveillance System (YRBSS) Questionnaire.
Results: Findings indicated that use of hookah was the most popular in girls and boys (59%) as compared with cigarette smoking (32.7%), drug use (7.3%), and alcohol consumption (16.7%). The prevalence of physical violence in and outside the school in one year, carrying weapons to school in a month, cigarette smoking in the school in one month, smoking hookah, and alcohol and opioid use during one month were more frequently observed in boys than girls. The use of the seat belt was more common among girls than boys, and the total prevalence of using the seat belt was 23.7%.
Conclusion : Given the high prevalence of high risk behaviors among high school students, it is necessary to develop a high risk behaviors surveillance system and use the obtained information to devise preventive measures at the individual, school, and family levels.

Abstract
Background & Objectives : Children who work or live on the street are one of key populations at risk for HIV and hard to reach for study or providing services. Here, as a methodological paper, we present the methods and steps of a rapid assessment and response (RARE) project conducted among street children in Tehran.
Methods : We applied a mixture of qualitative (literature review, focus group discussion, in-depth interview) and quantitative (structure interview) methods to collect data from key informants in non-governmental and governmental agencies as well as street children. We applied targeted sampling to recruit key informants and time location sampling to recruit street children.
Results: The study was conducted in eight steps to recognize the involved stakeholders, define target population (street children) and to guide on how to approach them (steps 1 to 2: Initial Consultation, Study Area Profile), to map the venues and gathering spots and ethnographic findings crucial for further recruitment into surveys (steps 3 to 5: Contextual Assessment, Population and Setting Assessment, Health Issues Assessment), assess the risk behaviors (step 6: Assessment Behavior Risk and Health), evaluate the response (step 7: Intervention Assessment), and develop an operational plan for improving the services (step 8: Developing an Action Plan).
Conclusion: RARE is a participatory mix research method with sufficient flexibility to study complex health problems such as stigmatized HIV risk behaviors among high risk and hard to reach populations and also to assess the health sector response.

Abstract
Background and Objectives: Foot-and-mouth disease (FMD) is one of major contagious animal. The purpose of this study was to evaluate the determinants associated with FMD occurrence in farms.
Methods: A case- control study was carried out in cattle farms. The cases were farms with new reports of FMD and controls were units without any report of FMD in last 6 month. For assessing the risk factors, a researcher- made questionnaire was used. Statistical analyses were done with SPSS version 16 using the logistic regression test.
Results: Purchase of new livestock [OR: 14.69 (CI95%: 4.29, 50.36)] and passing migratory livestock [OR: 13.32 (CI 95%: 1.74, 101.87) were identified as the risk factors of the disease. Visiting the farm by the vaccinator in last 2 weeks [OR: 0.17 (CI 95%: 0.05, 0.63)] and buying new livestock from the same village/ city where the farm is located [OR: 0.16 (CI 95%: 0.04, 0.58)] were considered as protective factors.
Conclusion: Considering the role of infected livestock in the country, the most important steps for effective preventation are: areadherence to biosecurity as well as quarantining new purchased animals, and informing and training farmers to not purchase new animals from farms that are located in the infected areas and around the times of outbreak.

Abstract
Background and Objectives: Salmonella contamination of broiler breeder farms is of great importance regarding transmission of the bacteria through the production chain of poultry meat. The aim of this study was to determine the prevalence and management related factors of Salmonella contamination in broiler breeder flocks in Iran.
Methods: This cross sectional study was carried out between 2013 and 2014 in 23 provinces of Iran. Fecal samples were obtained from 139 broiler breeder farms and were subjected to standard bacteriological tests for Salmonella isolation. The serogroups of isolated Salmonella were determined using standard serological tests. Relevant information of sampled holdings was acquired from the GIS system and used for risk factor detection.
Results: The prevalence of Salmonella contamination in broiler breeder holdings was 7.9% and the more positive samples were from Tehran and Fars provinces. The flock age (P = 0.019) and the number of poultry houses in the farm (P = 0.037) were major risk factors of Salmonella contamination in broiler breeder farms.
Conclusion: This investigation showed that the prevalence of Salmonella contamination in broiler breeder farms was relatively high. It is necessary to establish an appropriate program for controlling Salmonella contamination in broiler breeder farms. Regular sampling for early detection of contaminated farms would be very important in this case. Sampling from old flocks should be the first priority.

Abstract
Background and Objectives: Breast cancer is one of the most common malignancies in women which accounts for the highest number of deaths after lung cancer. The aim of the current study was to compare the logistic regression and classification tree models in determining the risk factors and prediction of breast cancer.
Methods: We used from the data of a case-control study conducted on 303 patients with breast cancer and 303 controls. In the first step, we included 16 potential risk factors of breast cancer in both the logistic regression and classification tree models. Then, the area under the ROC curve (AUC), sensitivity, and specificity indexes were used for comparing these models.
Results: From 16 variables included in the models, 5 variables were statistically significant in both models. Sensitivity, specificity, and AUC was 71%, 69%, and 74.7% for the logistic regression and 63.3%, 68.8%, and 71.1% for the classification tree, respectively.
Conclusion: The obtained results suggest that the classification tree has more power for separating patients from healthy people. Menopausal status, number of breast cancer cases in the family, and maternal age at the first live birth were significant indicators in both models.

Abstract
Background and Objectives: The aim of this study was to provide a clear description of the pre-hospital emergency setting and risk management in accidents and disasters in accordance with current Iran’s standards in different regions of the country. This study was part of the national project "Iran Roadmap (Neda 2026)".
Methods: The data of the major medical equipment was gathered from 48 medical universities covering all of the country's 32 provinces. Goal standards were obtained from the “Ministry of Health” and the “Department of Statistics for Medical Accident and Emergency Management Centers” in all universities. Coefficient of dispersion was calculated to evaluate any dispersion in major medical equipment.
Results: The results of this study showed that in 2017, the highest and lowest coefficient in “pre-hospital facilities” was related to the ambulance engine (301%) and the operational base personnel (93%), respectively. Nio national standards were implemented in “Risk Management in accidents and disasters needs” in most provinces of Iran. In 2026 estimates, all of the factors improved and dispersion decreased.
Conclusion: Despite the poor distribution of prehospital indicators in 2017, forecasting showed desirable conditions in distribution of facilities in the pre-hospital emergency and risk management of accidents and disasters.

Abstract
Background and Objectives: One of the applications of population attributable risk percent (PAR%) is to estimate the disease burden in a population exposed to several risk factors. Therefore, this study was conducted to estimates the PAR% of the space-time clusters of pulmonary tuberculosis.
Methods: In this study, the data of pulmonary TB cases were obtained from the health department of Hamadan University of Medical Sciences. After detecting significant clusters using the spatiotemporal scan statistic, PAR% was used to analyze the clusters and to detect the location of clusters more accurately.
Results: Four primary space-time clusters and three secondary spatiotemporal clusters were detected for patients with pulmonary tuberculosis and 92% of the patients who did not have a clear state in term of HIV infection. Despite differences in the location of clusters and PAR% attributed to them, the second primary cluster of pulmonary tuberculosis cases (consisting of the cities of Razan, Famenain and Kabudrahang) had the highest amount of PAR% that needs more attention.
Conclusion: The presence of significance spatiotemporal clusters in Hamadan highlights the necessity of the use of PAR% to distinguish cluster areas and to implement prevention and control policy. However, more analytical studies are needed to detect the on the determinants of the occurrence of pulmonary TB.

Abstract
Background and Objectives: Using the anthropometric indicators of children is one of the ways of monitoring their growth. Because of the racial divisions and levels of health and welfare, comparing these indicators with the global reference is not reasonable; therefore, designing a local reference seems necessary. This study aimed to evaluate the growth indices for boys and girls aged 5 to 18 years old living in Isfahan and to compare the indices with standard values.
Methods: In this cross-sectional study, 53,839 subjects were included. Percentiles of body mass index, height, and weight were calculated using the LMS method in the LMS Light software. After normalization of the growth indices, their mean and standard deviation were calculated for each age group and anthropometric indices curves were plotted versus the 5th, 50th and 95th percentiles of the NCHS reference.
Results: In all age categories, the mean SDS scores of BMI in boys and girls was -0.004 ± 0.029 and 0.014 ± 0.062, respectively, indicating no difference with reference values. However, the 95th percentile of the body mass index for the reference population was consistent with the 90th percentile for the population studied. Also, weight in boys below 13 years of age was higher than the reference line while in girls, weight was always higher than the reference value.
Conclusion: Due to differences in the pattern of growth and also lower anthropometric values, particularly among boys, it seems that a national growth curve can be a better guide for future decisions.

Abstract
Background and Objectives: A feasible and cost-effective tool is required to investigate young children' behaviors with regard to the risk of injury. The aim of this study was to assess the psychometrics of the Persian version of the Injury Behavior Checklist (IBC).
Methods: After validating the translation (backward-forward translation), the final version of the checklist was developed through content analysis and face validity and according to the comments of a panel of experts. The final version was distributed among 300 mothers of children aged 2-5 years referring to the kindergartens of Tehran. Convergent validity was evaluated by internal consistency through calculation of Cronbach's alpha coefficient, as well as item-total correlation. The reliability of the checklist was assessed through the test-retest method with participating 55 mothers and comparison of the scores of the two steps by correlation coefficient and interclass correlation coefficient (ICC).
Results: The content validity ratio was acceptable (0.6-1) for 100% of the items, and the content validity index was 0.93 for relevancy and clarity and 0.92 for simplicity. The Cronbach's alpha coefficient was 0.87. All 24 items of the IBC were acceptably and directly correlated with the total score of the tool (r=0.25-0.65). Reliability results also confirmed the test-retest reliability of the Persian version of the IBC (r=0.90; ICC=0.86).
Conclusion: The Persian version of the IBC is a reliable tool for investigation of risk taking and its association with different injuries in children aged 2-5 years.

Abstract
Background and Objectives: In Iran, rainbow trout farms exist in almost all provinces. Viral hemorrhagic septicemia is one of the most important infectious diseases of the rainbow trout which is a serious threat to the farming industry. This study was conducted to investigate outbreaks in 2014 and identify important determinants of the agent entry and disease occurrence in the farms.
Methods: Data were collected using a structured questionnaire and the disease was detected based on clinical signs and laboratory investigations by PCR methods.
Results: During 52 weeks of the study in 2014, 114 of 1140 (12.63%) farms were affected within 78 zones in 14 provinces. In multivariable analysis, illegal entrance of fries (odds ratio: 7.81, 95% CI: 3.63-16.8), illegal entrance of fish (odds ratio: 5.60, 95% CI: 3.03-10.35) and use of river as the water supply (odds ratio: 2.46, 95% CI: 1.51-4.02) were detected as risk factors associated with virus entry and disease outbreak in farms.
Conclusion: Observing biosecurity measures in the farm level, applying risk-based surveillance based on known risk factors, and assessing these factors on a regular basis are important in prevention and control of VHS.

Abstract
Background and Objectives: Evidence suggests that underlying diseases increase the severity of influenza and lead to hospitalization or death. This study was conducted to determine the risk factors associated with hospitalization of patients in Afzalipour Hospital, Kerman, Iran during an outbreak of H1N1 influenza in December 2015.
Methods: In this case-control study, the case group comprised 85 patients who were hospitalized for influenza and the control group included 51 patients who had influenza symptoms and were discharged after required evaluations and check-up. The data were collected from both groups on a daily basis for two weeks. For data analysis, descriptive analysis, logistic regression analysis, Lasso Regression, and likelihood ratio were used. Analysis was performed using the Stata version 12 and R software.
Results: Among the variables examined, after removal of additional variables, 12 variables were introduced into the multivariate regression. The history of pulmonary disease and diabetes increased the odds of hospitalization following influenza by more than 11 (OR = 11.6, P. value = 0.003) and 9 times (OR = 9, P. value = 0.01), respectively.
Conclusion: Underlying disease and factors play a major role in exacerbating the disease. Therefore, the health system should take the necessary preventive measures when outbreaks occur.
