Abstract
Background & Objectives : Migraine is the most common type of headache in children. Over 30% of patients have disabilities, so early detection and timely treatment is necessary to prevent attacks, increase learning, and prevent absenteeism. The aim of the study was to determine the prevalence of migraine in children.
Methods: In this cross - sectional study with two-stage stratified random cluster sampling the International Headache Society (IHS) for migraine diagnosis and (PedMIDAS) questionnaire were completed through interviews with the students’ parents. Data was analyzed with SPSS software and chi-square test.
Results : Of 1117 children with a mean age of 41.1 ± 9 years, 551 (49.3) were female and 556 (50.7) were male of whom 185 (56.16%) had a headache and 40 (2.16%) had migraine. Most of the time, the pain started on the first day of the week with a moderate intensity. Aggravating factors were physical activity and stress, and alleviating factors were sleeping and resting. The pain was bilateral and was accompanied by nausea and vomiting. The mean number of headache attacks in the past three months was 8.85± 7.65 which lasted for a mean duration of 6.38 ± 8.02 hours with a mean interval of 24.70± 26.21days.
The frequency of migraine in children by age and sex were not significantly different. More than of the children had a positive family history but were not visited by the doctor. About 79.37% of the students had first degree disability, %54.10 had second degree disability, %9.05 had third degree disability, and % 1.04 had fourth degree disability.
Conclusion: Given the increasing prevalence of migraine with age and the risk of chronic diseases and individual and social impairment, it is important to prevent headache attacks through early identification and moderation of the aggravating factors and education of non-medical preventive methods.

Abstract
Background & Objectives: This study examined the prevalence of behavioral disorders in middle and high school students in the Province of Qom.
Methods: A cross-sectional descriptive design was employed to investigate 762 students (382 middle and 380 high school students) who were selected through a multi-stage cluster sampling method. Data collection was performed suing the Woodworth Personal Data Sheet (WPDS), and the data were analyzed using descriptive statistics and chi-square test.
Results: The finding showed that the prevalence of behavioral problems in the total sample, and middle and high school students was 19.82, 22.72, and 17.1%, respectively. The prevalence of behavioral problems was higher in boys versus girls, is the middle school versus the high school, and in urban areas versus rural areas. The aggressive disorder and obsessive-compulsive disorder – Psychasthenia had the highest and lowest prevalence in both the middle and high school students, respectively. The educational level of students, parental education, parental divorce, parental death, and family income had significant relationships with behavioral disorders.
Conclusion: The prevalence of behavioral problems in the Province of Qom was found to be in the middle range in comparison with other studies conducted within and outside the country. However, attention should be paid to mental health policy-making in adolescents to decrease behavioral problems and prevent future issues.

Abstract
Background and Objectives: Cutaneous leishmaniasis (CL) is a public health problem in Iran and Kerman Province which is expanding to new foci. This study was conducted to estimate the incidence of CL by a simple and cost – effective method in a major focus of CL in the city of Kerman, southeastern Iran.
Methods: A combination of two longitudinal and cross – sectional studies was performed. First, the frequency of referred patients to the CL treatment clinic in 2009-2014 was assessed. Then, four highly infected zones consisting of 800 households in the city were selected. In addition, the relative proportions of referred and non – referred subjects were assessed. Eventually, the incidence of CL was calculated by dividing the number of CL cases over the total at risk population for the corresponding period (2009-2014).
Results: The mean annual incidence was 175 per 100000 (943 patients) in the city of Kerman, while it was 500 per 100000 people (0.5%) in the new foci. The highest CL infection was observed among the <25-year-old individuals but there was no significant difference between the sexes.
Conclusion:The incidence rate probably increased significantly following the 2003 Bam earthquake because of the migration of CL patients to southern, eastern, and northeastern areas of the city of Kerman. Since only 50% of the cases were passively referred to the CL treatment clinic, health authorities should actively detect CL cases by house – to – house visit for effective treatment strategies.

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: Ischemic heart disases are the main cause of mortality and morbidity in Iran. Diabetes mellitus (DM) is one of the most prevalent diseases in Yazd. However, little is known about the share of CHD associated with DM in Yazd.This study aimed to determine the potential impact fraction of ischemic heart disease associated with diabetes mellitus in Yazd-Iran.
Methods: The potential impact fraction (PIF) equation was used to calculate the estimates of CHD associated with DM in Yazd. Prevalence diabetes in Yazd were calculated from Yazd Health Study (YAHS) data, conducted in 2013- 2014 in Yazd Greater Area. The relative risk eof IHD associated with DM was extracted from Tehran Lipid and Glucose study.
Results: According to this study, by hypothetical reduction of DM prevalence in women from the 20.6 percent to null or optimistically to a minimum risk level of 20.3 percent, 23.6% and 0.3% of IHD will be reduced consequently. The corresponding value for men considering the DM prevalence of 15.9 percent at the theoretical zero level and feasible minimum prevalence of 17.7 percent, were 10.6% and -1.2%, respectively.
Conclusion: Given the high prevalence of DM and CHD in Yazd, more interventions to control DM is needed in Yazd by the health section.

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: 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: Alcohol consumption among various occupations' staff leads to many problems. Therefore, due to the importance of the issue, this comprehensive study was conducted to determine the prevalence of alcohol consumption among industrial workers.
Methods: In this descriptive cross-sectional study, the data were collected using a structured questionnaire through interview based on the workers’ self-reports. The participants included 13,128 workers across the country selected by multi-stage cluster sampling according to the population of labor workers and industrial centers in each province. The data were reported according to the consumption prevalence in the 10 spatial planning zones.
Results: In the optimistic situation, wokers in Ardebil (10.7%), Kermanshah (10.6%) and Guilan (7.1%) reported the highest frequency of alcohol consumption. The country’s mean prevalence of current consumption was 3.2% and the prevalence of alcohol consumption in life was up to 12.4% in the workers.
Conclusion: The data are based on the self-report of the participants. Therefore, the estimated prevalence rate is considered optimistic and below the actual prevalence. In the work environments of the country, especially in provinces with the highest frequency, special policies and interventions are needed to reduce the prevalence of alcohol consumption and minimize the harms caused by it.

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.

Abstract
Background and Objectives: A nosocomial infection (NI) is defined as an infection occurring in a patient after 48 hours of hospitalization or up to 72 hours after discharge from the hospital, which was not present or incubating at the time of admission. NIs increase hospital mortality, decrease patient satisfaction, reduce hospital productivity, and increase health system costs. This study was conducted to determine the prevalence of NIs in Iranian hospitals.
Methods: This study was performed using a systematic literature review and meta-analysis. Seven electronic databases and two search engines were searched using appropriate key words to identify research studies on NIs published in Persian and English languages from April 1997 to March 2019 in Iran. Finally, 15 empirical studies out of 89 records were reviewed. Data were analyzed using the Comprehensive Meta-Analysis software.
Results: The studies reported a prevalence of 0.32% to 9.1% for NIs in Iranian hospitals. The pooled prevalence of NIs in Iranian hospitals was 0.01 % (95% CI 0.0% - 0.02%). The most common type of infection was urinary tract infection and the most common microorganism was Escherichia coli. The highest rate of nosocomial infections was seen in the intensive care unit, internal medicine ward and hematology ward. Suction was the most important risk factor for nosocomial infections.
Conclusion: The prevalence of NIs in Iranian hospitals is low according to the published studies. Appropriate strategies should be implemented to prevent and control NIs.

Abstract
Background and Objectives: Using a random sample of women aged 15 to 50 years in Tehran, this study sought to estimate the lifetime prevalence of abortion (intentional and unintentional) and to identify its associated factors.
Materials and Methods: The control data of a population-based case-control study conducted in 2014 in Tehran was used in the present study. Data from 544 randomly selected women aged 15-50 living in municipality areas of Tehran were included in this study. A multiple logistic regression model was used to investigate factors associated with abortion and to estimate the adjusted odds ratios (ORs) and 95% confidence intervals.
Results: Overall, 102 women (18.8%, 95% CI (22.4% -15.8%)) reported a lifetime history of abortion. In the logistics regression model, being single (OR =3.46, 95% CI: 1.42-8.47) older age (OR = 1.07, 95% CI: 1.04-1.11) increased the odds of a positive lifetime history of abortion. However, having a child (OR = 0.27, 95% CI: 0.11-0.65)), more education years (OR = 0.89, 95% CI: 0.82-0.96)) and higher religious beliefs (OR = 0.65, 95% CI: (0.45-0.93)) decreased the odds of a positive lifetime history of abortion..
Conclusion: High reported lifetime prevalence of abortion in the present study and its subsequent risks to maternal health highlight the need for educational interventional programs taking into account the level of education and knowledge of mothers along with their religious.

Abstract
Background and Objectives: Dementia is a chronic disease that imposes a huge financial and social burden on the health system. Knowledge of the prevalence of dementia is essential for healthcare planning and ensuring that there is an adequate service for people with the condition. Considering that the prevalence and geographical variation of dementia are not well known in Iran, the present study was conducted to investigate the prevalence of dementia and its geographic variations in Iran.
Methods: In this study, the prevalence of dementia was estimated indirectly using the frequency of prescribed specialized medicines in one year by generic and brand names in each province. Choropleth maps were used to visually assess the geographical variation of dementia prevalence at the provincial level. Moran I and Getis-Ord Gi (Gi) geographical tests were used to investigate the spatial autocorrelation and geographical variability of dementia prevalence at a significant level of 0.05, respectively.
Results: In this study, the prevalence of dementia was 49.6 and 508.9 in 100000 in the general and over 60-year population, respectively. In the general population, the lowest prevalence was in Hormozgan Province (9.4/100000) and the highest prevalence was in East Azarbayjan Province (96.4/100000). In the over 60-year population, the lowest prevalence was in Hormozgan Province (141.5/100000) and the highest in Isfahan Province (862.5/1000000). According to Moran I and Getis-Ord Gi (Gi) tests, spatial autocorrelation and geographical variability of dementia prevalence were not significant.
Conclusion: The prevalence of dementia in the Iranian over 60-year population is lower compared to western countries; however, it is comparable with the reported dementia prevalence from developing countries. It should be noted that the dementia prevalence is high, similar to developed countries, in some developed provinces of Iran.

Abstract
Background and Objectives: Serological studies are based on the detection of antibodies. However, the produced antibodies decrease over time; therefore, such methods cannot provide a valid estimate of prevalence and incidence. The present study aimed to determine the serum prevalence and cumulative incidence in the Ravansar cohort population (Youth and RaNCD Cohort) in October 2020.
Methods: A random sample of 716 people aged > 18 years old were selected from the participants in the Ravansar cohort study in October 2020. Euroimmun anti-SARS COV-2 IgG ELISA kits (Lübeck, Germany) were used to measure antibody levels. Seroprevalence was estimated with considering of cut-off = 1, and cumulative incidence (modified and modified based on test specificity) was determined using modeling.
Results: In the present study, the serum prevalence of COVID-19 viral infection in the Ravansar cohort population from 22 October 2020 to 18 November 2020 was estimated to be %35.16 (95%CI: %31.64, %38.79). Modified Cumulative incidence and modified based on test characteristics from 20 February to 18 November 2020 were estimated to be %68.85 and %67.71, respectively.
Conclusion: Although very high cumulative incidence may be a sign of approaching herd immunity, adherence to health protocols is still recommended due to the potential role of asymptomatic cases in transmitting the disease to other members of the community; and the presence of new variants of the virus and reduced antibody levels should be considered.

Abstract
Background and Objectives: Indirect methods for estimating hidden populations are essential. The present study aimed to assess the prevalence of cigarette and waterpipe consumption in the Arak metropolis, Iran, directly and indirectly through network scale-up.
Methods: This cross-sectional study was conducted on 1,604 participants. Daily and weekly cigarette and waterpipe consumption data were collected to measure the prevalence directly. The indirect network scale-up method was used to estimate the size of cigarette and hookah smokers. A confidence interval of 95% was considered.
Results: About 49.9% of the participants were men. The average age of men was 39.8 and women 38.7 years. In the direct method, the prevalence of smoking at least one cigarette per day during the last year in women and men was 1.8% (1.0-3.0) and 38.3% (34.9-41.9), respectively. The prevalence of using waterpipe at least once a day during the last year was as much as 0.9% (0.03-1.8) and 4.1% (2.8-5.7) for women and men. In the indirect method of network scale-up during the last year, the prevalence of continuous smoking was 4.8% (4.3-5.0) in women and 19.7% (19.6-19.9) in men. The prevalence of waterpipe in women was calculated at 7.8% (7.8-8.0) and 9.8% (9.7-9.9) in men.
Conclusion: Based on the results, the prevalence of waterpipe and cigarette smoking was high in the Arak, especially among young people. It is suggested to the health system policymakers to pay attention to measures related to reducing the prevalence of these two risk factors, especially among young people, in their health plans.

Abstract
Background and Objectives: Depression is one of the most prevalent mental disorders among students associated with a major decline in academic and social performance. This study was carried out to determine the prevalence of depression in Iran's nursing students.
Methods: the research was conducted as a systematic review and meta analysis, all published scientific articles related to the prevalence of depression in nursing students were searched in 5 databases (Web of Science, Scopus, PubMed, SID, Magiran) and Google Scholar search engine and then their quality was evaluated. The heterogeneity of the studies was investigated using the I2 index and meta-regression model to evaluate heterogeneity-prone variables at a significance level of 0.05. Ultimately, 9 articles met the criteria for inclusion in this study and were analyzed using Comprehensive Meta-Analysis (CMA) software.
Results: Based on the random model, the prevalence of depression in Iranian nursing students was equal to 3.2% (2.1 – 4.5; 95% confidence level). Results showed that the highest prevalence of depression in nursing students was 6.2% (5.3-7.1; 95% confidence limit) in Sistan and Balochestan province in 2004, while the lowest prevalence was 0.8% (0.5-1.2; confidence limit 95%) in Esfahan and Qom provinces in 2016. Also, there was a significant relationship between the calendar year, sample size, average age, and prevalence of depression in Iranian nursing students (P<0.05).
Conclusion: The results showed that the prevalence of depression in nursing students was 3.2%, which decreased with the increase of the calendar year and average age. Nevertheless, policymakers and managers must take measures to reduce depression.
