Abstract
Background and Objectives: Noise-induced hearing loss is a prevalent work-related morbidity in the country. We determined the strength of association between hearing loss and occupational noise exposure as the first step in prevention programs.
Material and Methods: A historical cohort study involving 100 exposed and 31 non-exposed subjects was conducted. Noise exposure was estimated using sound level meter BSEN 60651, Type 2. Past noise exposure was estimated using the existing data on the place and type of work. Audiometry was used to assess hearing loss in each subject in 3- year intervals on an occupational cohort from 1993-2004.
Results: Noise-induced hearing loss was found in 49% (49 subjects) of the exposed group and 9.7 %( 3 subjects) of non-exposed group (p<.0001). Nobody used any form of hearing protection routinely in either group. Relative risk for noise-induced hearing loss was 5.1(CI95%: 1.7- 15.1).Time at risk was estimated 24.9 years (22.7-27.1) in exposed and 22.2 years (20.7-23.7) in unexposed group by survival analysis.
Conclusion: More legislation, hearing conservation programs, and surveillance and biological monitoring of work sites and workers are required to prevent occupational hearing loss. Planning strategies for noise assessment and control can help improve the work environment. Gross occupational exposure to noise has been demonstrated to cause hearing loss and the authors believe that occupational hearing loss in the country is a widespread problem.

Abstract
Background & Objectives: The epidemic of HIV has been become worldwide. Infected people with HIV which are
most intravenous drug users (IDUs) and/or people who have unsafe sex are important source of transmission of
infection to other persons in a community. Since there is little known about the knowledge and attitudes of HIV
positives about HIV in Iran, therefore we decided to measure the level of knowledge and attitudes of this group
in Golestan province in compare with individuals with risky behavior.
Methods: This cross-sectional study was conducted on 54 HIV+ persons and 134 people with high risk behavior
individuals in 2007 year.
Results: Our study showed that HIV- (High risk group) cases had higher education level (P=0.034). Rate of
jobless was higher in HIV+ persons (P<0.001). HIV+ cases had lower income (P=0.037). Both groups had
moderate knowledge and poor attitude on HIV/AIDS. Level of attitude in HIV+ positive persons was lower than
high risk group (P=0.05).
Conclusion: It is concluded that these susceptible persons and also infected individuals with HIV regardless of
their socio-economic levels need more continuous education in structured programs.

Background & Objectives: Human papillomavirus (HPV) infection seems to be the
most common sexually transmitted infection. High-risk (HR) human papillomavirus
(HPV) prevalence has been shown to correlate well with cervical cancer
incidence rates. Since there is little known about the epidemiology of this
infection in Tehran, we designed to estimate the prevalence of HPV in some
areas in Tehran.
Methods: Cervical
specimens were obtained from 825 married women aged 21-59 years from the
general population of Tehran, Iran according to the standardised protocol of
the IARC International HPV surveys. HPV was detected using a GP5+/6+ PCR-based
assay.
Results: HPV
prevalence in the general population was 7.8% (5.1% of high-risk types), with
no statistically significant variations by age. Cervical intraepithelial
neoplasia was diagnosed in 4.1% of women, of whom 35.3% were HPV-positive.
HPV16 was confirmed as the most common type among women with both normal (1.8%)
and abnormal (8.8%) cytology. HPV positivity was significantly higher among divorced
women, women in polygamous marriages and those reporting husbands' extramarital
affairs.
Conclusion: However
the prevalence of HPV seems not high in comparison with other international
data, more molecular and seroepidemiological survey in national level needs to
have a better perspective.

Abstract
Background & Objectives: Tuberculosis (TB) is one of the major infectious diseases in Iran and has pulmonary and extra-pulmonary manifestations. Considering the differences in the distribution of the cases across different regions, we decided to study the geographical distribution, epidemiologic characteristics, and disease pattern in Lorestan.
Methods: This ecologic (descriptive analytical) survey was done in Lorestan between 2002 and 2008. The data was collected from the Health Department of Lorestan University of Medical Sciences and included the history of 1481 patients suffering from TB. The study variables were sex, disease type, residential location, age, and year. The data were analyzed using statistical package SAS 9.2 and descriptive and inferential statistics were applied.
Results: From 1481 registered patients 58.4% were male and 41.6% were female among which 68.74% and 29.98% lived in urban and rural areas and 1.28% were nomads. The mean age of the patients was 41.87. The highest and lowest incidence rates were observed in Khoram Abad (19.38 per 100000) and Azna (7.04 per 100000), respectively. Using Poisson regression, it was observed that the effects of age structure and residency on the incidence rate were significant.
Conclusion: The percentage of nomads was identified as the most important demographic factor in the incidence rate of TB in Lorestan. Allocation of better resources and appropriate training can be effective in controlling and preventing the disease.

Abstract
Background and Objectives : Breast cancer is the second most common cancer among Iranian women. The peak age of breast cancer in Iran is one decade lower than the global estimates. The aim of this cross-sectional study was to estimate the burden of breast cancer in Iranian women in the country level.
Methods: In this study, the CANMOD software was used for the calculation of DALYs as the sum of YLL and YLD. The required data was the population of the Iranian women, mortality due to breast cancer, incidence cases of breast cancer, and mean time of the stages of breast cancer that was obtained from the Mortality Registry System, Cancer Registry System, and expert panel views .
Results : In this study, the total burden of breast cancer in Iranian women was 75811 years in 2009. Moreover, the years of life lost (YLL) was 54938 years while years lived with disability (YLD) was estimated 20873 years. The rate of DALYs per 100000 female population was 220.9 years. The peak age of breast cancer burden was in the age group 45-59 years. The incidence to mortality ratio was 3/2.
Conclusion: The incidence rate, mortality rate, and the burden of breast cancer in Iranian women increased in 2009 when compared to a previous study in 2003. The findings of this study may provide Iranian health managers with some information on the determinants of the burden of breast cancer in order to design preventive measures as well as screening programs for early detection of breast cancer.

Abstract
Background and Objectives: Colorectal cancer is the fourth leading cause of cancer death worldwide. Annually 1430000 cases would be diagnosed and half of these people would die of the disease. In Iran, colorectal cancer is the fifth common cancer among men and is the thirdamong women. This study was designed to estimate survival rates for patients with colorectal cancer and related factors.
Methods: During the 1384 to 1388 years 24,807 patients diagnosed with colorectal cancer were recorded in the Cancer Registry of the Ministry of Health and Medical Education. Age, gender, marital status, education, occupation, place of residence, tumor diagnosis, the clinical and demographic factors in colorectal cancer as effective on survival entered in Aalen’s additive hazard model and diagram Aalen's was used to study the effects of these factors over time. R 3.2.0 software was used for data analysis.
Results: Stage of tumor had a significant association with survival rates. In this study 1 to 5 year survival rate for patients with stage II tumors, was 100%, 98%, 96%, 93% and 93% respectively and for patients with stage III tumors 99%, 97%, 94%, 90% and 84%, respectively.
Conclusion: In spite of using Cox model in survival analysis by many researchers, Aalen’s model may yield new insights in prognostic studies of survival time of patients with colorectal cancer over time. Our results suggest that early detection of patients in primary stage is important to increase survival.

Abstract
Background and Objectives: Determining and monitoring the age at myocardial infarction (MI) and its comparison in various regions is one of the vital and basic principles for the management of MI.This study was conducted to determine the age at the first MI in Iran.
Methods: In this cross-sectional, analytical study at a national level, the data of 20750 new MI patients registered in 2012 in 31 provinces of Iran according to the cardiologist’s diagnosis, World Health Organization criteria, and the codes ICD10: I21-I22 were used. The calculations were done using the Stata 12 software.
Results: The mean±SD of age at the first MI was 61.2±13.4 years in all patients in Iran. Moreover, 15033 (72.4%) patients were male with a mean age of 59.6±13.3 years. The mean age at MI in men was lower than women (65.4±12.6 years), showing a statistical significance (P<0.001).The mean age at MI was different among Iran provinces, with a statistical significance (P<0.001). The lowest mean age at the first MI was seen in the patients living in Semnan (59.1±12.9 years), followed by Tehran (60.4±13.5 years), Sistan va Balouchestan (60.3±13.9 years), and Lorestan (60.1±14.5 years), with a significant difference from the mean age of the patients in Ardabil (63.2±15.1 years) and Zanjan (64.4±112.8 years) (P<0.019).
Conclusion: Our study demonstrated that the age at MI was approximately five years younger in men than women. This studyprovided the ground for monitoring the age at MI, and more effective management of cardiovascular diseases in Iran.

Abstract
Background and Objectives: Ahvaz has become one of the most polluted cities in the world. Only on 11 November 2013, over one thousand residents in Khuzestan Province attended the nearest health center with severe symptoms, particularly shortness of breath, cough, wheezing, and high blood pressure. During a week, more than 7 thousand patients were registered with this syndrome. This study was conducted to investigate the evidence for the confirmation of an epidemic in acute respiratory syndrome among the residents of Ahwaz in November 2013.
Methods: In this cross-sectional study, we evaluated the data of the use of drugs related to acute respiratory attacks from November 2008 to 2013 in Ahvaz. Then, we conducted a descriptive study on the general population. The sample size was 120 and the study participants included different segments of the general population. The data collection tool was a researcher-made questionnaire and the data were analyzed using SPSS.18.
Results: The use of the respiratory drugs increased from 2008 to 2013. The drug consumption was markedly higher in November 2013. In the study of the general population, 93% of the participants declared that they had never seen a similar event, and 92.5% mentioned that they had never heard of a similar occurrence.
Conclusion: Due to the significant increase in respiratory medicine in November 2013 and the unexpected nature of the event, an epidemic seems to be obvious.

Abstract
Background and Objectives: Colorectal cancer is the third most common cancer in men and the second most common cancer in women in the world. The colorectal cancer screening program was conducted in Iran as a pilot in the late 2010 with the aim of reducing the burden of colorectal cancer. The aim of this study was to evaluate the colorectal cancer screening program in Iran.
Methods: This cross-sectional study was conducted on data from the pilot colorectal cancer screening programs. First, the indicators of the colorectal cancer screening program were determined through a comprehensive review of scientific databases, interviews with experts and implementation of pilot evaluation. Then, the indicators were calculated through descriptive analysis using SPSS version 18.
Results: The indicators and their values were as follows: coverage rate 33.04%, participation rate 53.3%, percentage of consulted people 99.6%, percentage of blood samples 37%, percentage of colonoscopy 54.8%, cancer detection rate 2.7%, and polyp detection rate 18.1%. Among people who gave blood samples 1.6% had familial adenomatous polyposis (FAP) syndrome, 43.06% had hereditary no polyposis colorectal cancer (HNPCC) syndrome, and 29% were sporadic cases.
Conclusion: The screening program in Iran has differences with other countries which have affected the indicators.

Abstract
Background and Objectives: Data plays a major role in a health care system in development planning and health services support if they are correct, timely and accessible. The data of the Ministry of Health are not readily available and the limited access reduces their value. The aim of this study was to explore the challenges of access to the data of the Iranian Ministry of Health.
Methods: This qualitative study was conducted in 2015. Twenty-three academic and administrative experts were selected purposefully. Semi-structured interviews were conducted to collect the data. The transcripts of the interviews were analyzed using content analysis.
Results: The results of this study provided 4 main themes (challenges of access to the data of the surveillance system, challenges of access to the data of national surveys and ordered projects, challenges of access to the data of electronic health records, and challenges of access to confidential data) and 15 sub-themes.
Conclusion: Given the multiple challenges of access to the data of the Iranian Ministry of Health, it is suggested to design access mechanisms in a systematic manner in the form of guidelines and organizational structures for data access management.

Abstract
Background and Objectives: Colorectal cancer is the fourth most common cancer and the fifth cause of cancer-related mortality in Iran. This study aimed to determine the incidence of colorectal cancer in men and women and to investigate its relationship with the human development index (HDI) and its components in Iranian provinces.
Methods: This ecological study was conducted to assess the correlation between age-specific incidence of colorectal cancer in men and women and the Human Development Index. We used the data of the Iranian Cancer Registry and Statistical Centre of Iran. We used a bivariate correlation method to assess the correlation of ASR and HDI. P values less than 0.05 were considered significant. All reported P-values are two-sided. Statistical analyses were performed using the SPSS software version 23.
Results: The highest incidence of colorectal cancer in men was seen in Tehran (78.16), Eastern Azerbaijan (41.14), and Semnan (62.13), and the highest incidence of colorectal cancer in women was seen in Tehran (47.18), Semnan (80.14), and Eastern Azerbaijan (82.12), respectively. The results showed that the incidence of colorectal cancer in men (r = 0.605) and women (r = 0.661) had a positive significant correlation with the Human Development Index (P<0.001).
Conclusion: The incidence of colorectal cancer was high in provinces with a higher human development index. Therefore, evaluation of the incidence of cancer by the Human Development Index and its components can be used to show a clearer picture of the distribution of cancer in each country and may be useful for cancer prevention plans.

Abstract
Background and Objectives: The prevalence of HBV infection among injection drug users (IDUs) is higher than the general population due to high-risk sexual behaviors and the needle sharing. The aim of this study was to determine the prevalence of HBV infection and its effective factors among IDUs of Kermanshah Province in 2016.
Methods: This ia descriptive-analytic study was performed in 606 male IDUs in Kermanshah Province in 2016. Data were collected through questionnaires and interviews. HBV was also evaluated through blood tests using the rapid test. Simple and multivariate logistic regression analyses were applied to investigate the factors affecting HBV infection. Data were analyzed using STATA-12 software.
Results: The prevalence of positivity HBV antibody was 3% (95% CI: 1.61- 4.32) among male IDUs. According to the results of unit-variable logistic regression analysis, the duration of drug injection (OR = 1.08, 95% CI: 1.02-1.15) and the number of daily injections (OR = 1.38, 95% CI: 1.05-1.81) were risk factors for HBsAg positivity but there were no significant associations in the multivariate regression model.
Conclusion: The prevalence of HBV is much higher among IDUs than in the general population. These populations are at risk for viral infections such as HBV; therefore, it is recommended to provide necessary education about the prevention methods as well as the necessary screening for them.

Abstract
Background and Objectives: One of the causes of neonatal death and death in children under the age of five is premature birth of infants. The purpose of this study was to identify the risk factors associated with preterm infant birth in pregnant women.
Methods: This is a case-control study on mothers referring to comprehensive health centers in the provinces of the country. Descriptive analysis of variables was reported as percentage and frequency. In data analysis, logistic regression analysis was used at a significant level less than 0.05.
Results: In this study, 2463 pregnant women (668 cases as cases and 1795 as controls) were examined. There was a significant relationship between the place of residence (OR=0.702, P=0.002), level of maternal education (OR=1.920, P=0.027), degree of twin (OR=4.953, P=0.001), interval between pregnancies (OR=1.821, P=0.009), specific disease (OR=1.694, P=0.010), nutritional status of the mother (OR=1.420, P=0.024), physical activity (OR=1.591, P=0.001), Sleep patterns (OR=0.634, P=0.008) and history of stillbirth (OR=0.247, P=0.001) associated with the birth of premature infants.
Conclusion: Preterm infant birth is one of the main causes of neonatal death. Therefore, some of the birth defects of the premature baby can be prevented. It is possible to reduce the risk factors for the birth of a premature baby by improving the quality of pregnancy care and changing the lifestyle of the pregnant mother, and by raising awareness and creating a healthy and safe environment for the mother.

Abstract
Background and Objectives: The study aimed to analysis the psychometric properties of the health system resilience scale, assessing it and to introduce a conceptual model for qualitative analysis of Iran health system in the face of the civid-19 crisis.
Methods: In this Mixed-method study, the determination of face and content validity was performed using 8 experts. The structure validity was investigated in a cross-sectional study through an electronic survey of 178 actors in the Iran health system. Resilience has been assessed in five dimensions using 5point Likert scale.
Results: The percentage mean score of the Iranian health system resilience in the face of the Covid19 crisis was 41/08 and in the moderate level. The percentage mean score (standard deviation) for 5 dimension include awareness 39/2 (21), diversity 38/7 (21), self-regulation 36 (20/6), integration 39/9 (21/5) and adaptation 41/2 (21/8). Confirmatory factor analysis indicated the appropriate fit of the information with the five-component structure.
Conclusion: The maximum score of resilience dimension belongs to adaptation and the lowest to the self-regulation indicating that it requires interventions to involve the private sector, and to design a new delivery system for crisis situations. The questionnaire can be used as a standard instrument for assessing the health system resilience.

Abstract
Background and Objectives: Immune deficiency syndrome is an epidemic disease. During immunodeficiency caused by HIV, infections such as tuberculosis, hepatitis B and hepatitis C may occur. Given that the transmission of these infections is similar to that of HIV, the risk of HIV infection with these infections is high. The purpose of this study was to determine the prevalence of common HIV infections and the related risk factors in HIV positive individuals.
Method:This study was conducted as a retrospective cohort study performed on 3047 HIV patients at Imam Khomeini Counseling Center in Tehran who have been admitted in 2004 -2018.Required data were extracted from patient records and entered into Excel software. For data analysis, SPSS version 21 was used.
Results: The mean age of the patients was 44.24 ± 9.46 years and 77.3% of them were male. Of them, 98 (3.2%) were co-infected with hepatitis B, 961 (31.5%) were co-infected with hepatitis C, and 415 (13.6%) were co-infected with tuberculosis. According to the results, hepatitis B and hepatitis C had a significant association with age, marital status, gender, education, prison history, history of injection, history of addiction, and needle sharing.
Conclusion: Due to the common route of HIV transmission and these infections, there is the possibility of co-infection. The demographic variables and behavioral factors are the most effective risk factors for developing co-infections.
