Abstract
Background & Objectives: Prevention and control of brucellosis in animals is the main route of its prevention in human. After detecting a brucellosis outbreak in an industrial dairy cattle farm in Isfahan province in Iran, an epidemiological investigation was carried out to determine prevalence of seropositive cows and incidence rate inorder to eliminate positive couws.
Methods: This study was carried out to determine abortion rates in caws. RBPT, SAT and 2ME serologic tests were used for detecting infected cows and Brucella agar for isolation of bacteria. Data analysis was performed by Chi-square test and calculation of cumulative incidence ratio.
Results: Of total 1395 female cows above 4 months age, 706 infected animals were found during investigation (March-December 2011). Incidence of abortion in infected cows was significantly higher than no infected
(34% versus 14%, P<0.05). Culture for 47 milk samples was positive for brucella out of 100 milk samples.
Conclusion: Attention to using reduce dose of RB51 vaccine, controlling of import animal in farm besides biosecurity are the main factors for prevention of similar outbreaks in dairy farms.

Abstract
Background & Objectives: Relationship between jobs and different aspects of health, including quality of life has been considered by researchers however the employment aim has risen in Iranian women in Iran but there is little known about the quality of life in this group, therefore the aim of this study was to investigate the relationship between employment and quality of life of women in the city of Zabol.
Methods: This cross-sectional study was carried out during 2009-2010 in Zabol, Iran. The sample consisted of 420 women selected randomly from health care centers. Health-related quality of life was assessed using the SF-36 and classified using k-means clustering method. The relationship between the independent variables with the quality of life was assessed by multinomial logistic regression.
Results: The mean age of participants was 30.46 ± 8.75 years. Quality of life indicated as low (35.4%), medium (33.7%) and high classes (30.9%), respectively. The results indicated that employed women were more likely than housewives to hadhigher quality of life. An increase age, significantly reduced respectively five and four percent of chance to had moderate and high level of quality of life.
Conclusion: More than half of women had medium and low quality of life. Increasing age was associated with decreased quality of life, but employment was an independent predictor for higher quality of life.

Abstract
Background and Objectives: Congenital hypothyroidism is one of the reasons for mental retardation and premature death of infants. Since identification of the determinants of hypothyroidism plays a significant role in its prevention, this study was conducted to determine the prevalence of congenital hypothyroidism and to investigate its determinants in newborn infants.
Methods: This study was a secondary analysis of the data of the neonatal congenital hypothyroidism screening program. Hypothyroidism was diagnosed based on the Thyroid Stimulating Hormone (TSH) level in the heel prick blood samples on the third to fifth day of life. The data of infants born in Jiroft hospitals were collected from Jiroft Health Center and analyzed using descriptive statistics and Poisson regression test.
Results: In this study, 4998 newborns (2450, 49.02% female, 2548, 98 / 50% male) were investigated. The study samples were newborns born from March to March 2016. The prevalence of congenital hypothyroidism was 1 in 135 live births. The prevalence of congenital hypothyroidism was higher in babies born by cesarean section (IRR = 2.2, 95% CI =1.1-4.1), newborns admitted to the NICU (IRR = 4.6, 95% CI=2.4-8.9), and babies with high birth weight (IRR = 5.3, 95% CI =3.5-8.1).
Conclusion: The prevalence of hypothyroidism was higher in this study compared to other studies. Its prevalence was higher in males than in females. Genetic and environmental differences may explain this difference. The prevalence of hypothyroidism was higher in infants born through cesarean section and newborns hospitalized in NICU.

Abstract
Background and Objectives: Due to the importance of cutaneous leishmaniasis, the national leishmaniasis project began in 2007 in Iran. The aim of the present study was to evaluate community interventions in changes in the incidence of cutaneous leishmaniasis in Isfahan Province from 2002 to 2018: an Interrupted time series regression analysis.
Materials and Methods: The present study was a repeated cross-sectional study. The incidence and 95% confidence interval were used to describe the disease trend. Data were entered into the Excel and analyzed using STATA14 software at a significance level of 5%. Intermittent time series regression analysis was used to evaluate community interventions in changes of leishmaniasis incidence.
Results: from 2002 to 2018, the data of 43,904 patients with leishmaniasis was registered in Isfahan Health Centers. The mean (standard deviation) age of the patients was 23.99 (19.03) years. The incidence had a decreasing trend after the interventions in all affiliated cities and the whole province.
Conclusion: The preventive intervention programs of the provincial health center have been rather successful and have reduced the incidence of the disease in the years after the intervention, so that despite the large number of confounding and influential factors regarding this disease, preventive intervention programs have led to disease control according to the reported annual incidence.

Abstract
Background and Objectives: The aim of this study was to investigate the relationship between socioeconomic status and non-communicable diseases (NCD) risk factors in one of the northern counties of Iran.
Methods: A descriptive-analytical cross-sectional study was conducted in Langrud County in 2019. In this study, 906 rural and urban households were surveyed using mixed sampling. The data collection tool was the standard questionnaire of "NCD disease care system". Households’ exposure to NCD behavioral risk factors (including unhealthy diet, sedentary lifestyle and smoking) in different socio-economic groups was examined and compared with logistic regression models using the STATA software.
Results: The probability of smoking in illiterate subjects and those with unfinished high school education and high school diploma was 5.1, 7.5 and 4.2 times higher than those with university education (OR = 5.1,7.5,4.2; P <0.05). The probability of unhealthy diets in the first and second quartiles of income (very low and low income) was 3.4 and 2.6 times higher compared to the people in the fourth quartile of income (high income) (P <0.05; OR = 3.4, 2.6).
Conclusion: The micro-level socioeconomic inequalities (within the county) have a significant relationship with households’ exposure to NCD risk factors. Reducing socio-economic inequalities at the micro level should be considered as an appropriate tool to reduce health inequality at the macro level.

Abstract
Background and Objectives: Screening for home contact with TB patients is essential to identify new infections. This study aimed to evaluate the tuberculosis status in family members of patients with pulmonary tuberculosis in Bam.
Methods: This cross-sectional study was conducted as a census of patients' family members whose records are registered during 2013-2019 in Bam Health Center. Patients' information was collected based on a checklist, and then sputum smear-positive patients were identified using tuberculin and sputum smear tests.
Results: Ninety-seven of the patients had a positive sputum smear test result. Based on the records of these patients, 237 members of their families were examined as contact persons. Most of the patients were female and in the age group of 40-50 years; 76.8% of them had unprotected close contact, and 78.9% had a history of permanent contact with patients. Five (2.1%; 95% confidence intervals: 0.7-4.9) sputum-positive smear pulmonary tuberculosis cases were found in contacts of patients, most of them were over 50 years old and primarily women. 40% of these people had unprotected close contact, and 80% had a house with less than 70 square meters.
Conclusion: in this study, 2.0% of the family members of patients were sputum smear-positive. Identifying patients and following them up is essential to prevent the spread of tuberculosis in those people around them. Therefore, screening the patient's family members can significantly help ease the disease burden in Iran.

Abstract
Background and Objectives: Masks play a crucial role in preventing and controlling viral epidemics transmitted predominantly through the air. This study aimed to develop and validate a tool to measure people’s attitudes and behaviors related to mask usage during highly contagious viral epidemics.
Methods: In this psychometric study, the initial questionnaire was developed and face validity and content validity were assessed by 17 experts and three lay experts. Reliability was evaluated through internal consistency using Cronbach’s alpha and test-retest reliability using the Intraclass Correlation Coefficient (ICC). Construct validity was measured using exploratory factor analysis (EFA) with the principal component extraction method and Varimax rotation.
Results: Based on a review of previous studies, an initial 27-item questionnaire was crafted. During the face validity stage, two items were excluded. Through calculating the Content Validity Ratio (CVR) and the Content Validity Index (CVI), three and one items respectively removed. The average scale level content validity index (S-CVI/Ave) was 0.95. Cronbach's alpha coefficient was found to be 0.76 for attitude and 0.66 for practice sections; the ICC was equal to 0.873. EFA revealed two factors explaining 63.98% of the total variance.
Conclusion: This questionnaire demonstrated sound reliability and validity in Persian, providing an effective means to assess attitude and behavior related to mask usage during highly contagious viral epidemics. It stands as a valuable tool for use in Iran and other countries.

Abstract
Background and Objectives: The influential role of epidemiologists in improving health outcomes and conducting pertinent research becomes apparent when they are strategically positioned and available in sufficient numbers within a nation. This study aims to identify potential job positions in epidemiology within both governmental and non-governmental sectors while estimating the necessary workforce of epidemiologists in the country until 2027.
Materials and Methods: The present study was conducted as a combination in two quantitative and qualitative parts. In the qualitative part, interviews were conducted with experts, policy makers, graduates and students of this field in the field of job opportunities. In the quantitative part, the number of epidemiologists needed was estimated using modeling and parameters obtained from the review of the literature and the opinions of experts in this field. In this study, the current and near future needs up to 1406 have been considered.
Results: Based on the interviewes, job opportunities for epidemiologists in the country encompass diverse domains, including problem management and analysis, conducting applied research, data analysis, dashboard development, teaching, training, and future-oriented work (forecasting). Acounting for lost job opportunities, the estimated number of epidemiologists required in the country until 2027 is 1122 individuals, that most of them contribute to the country's health system if job opportunities are created. The highest demand for epidemiologists was identidied in units of the Ministry of Health, medical universities, research centers, and hospitals.
Conclusion: Estimating the number of epidemiologists needed using modeling in the country and paying attention to the current number of graduates, reveals that the growth of this field and the increase in graduates can only occur if job opportunities are clearly defined, created, and implemented across proposed job levels.

Abstract
Background and Objectives: Given the significant migration of educated individuals, particularly epidemiologists, throughout the country, it is crucial to investigate the underlying causes. This article presents the findings of an extensive study that sought to explore this issue by gathering insights from experts in the field.
Methods: The study was conducted using qualitative methods, employing content analysis. Data were collected between summer and autumn 2023 through semi-structured interviews with 32 epidemiologists in the country. Analysis followed the steps outlined by Lundman and Graneheim, with coding facilitated by MAXQDA software.
Results: The main challenges of epidemiology in Iran were divided into six main categories. In the field of graduate students, problems in recruitment and employment due to the lack of suitable careers, infrastructure and structural problems of the system, research problems and insufficient knowledge about the performance of this field are the most important challenges, and in the field of students, education problems, structural and infrastructure problems were reported. Also, the main reasons for the migration of epidemiologists were the lack of meritocracy and specialization, inappropriate privileges (including the application of unconventional recruitment quotas), lack of a job market and opportunities for graduates, and inadequate compensation and benefits.
Conclusion: Based on the results of this study, it seems that the migration of epidemiologists as a valuable human resource abroad is a serious concern and problem. The lack of a suitable job position and ambiguity in the path to career advancement due to non-adherence to the meritocracy and skill-building system have increased the motivation to migrate in this group.
