Background: The trend of increasing overweight and obesity among children is a huge burden on health systems. In this regard, the growing availability of processed foods, often energy dense and nutrient poor, has become a major concern. Changing this trend will require evidence-based policies. Aims: This systematic review aimed to identify the most common processed/ultraprocessed foods consumed by 4–12-year-old Iranian children. Methods: We searched PubMed, Scopus and Web of science, as well as Persian scientific search engines, including Iran Research Information System, Scientific Information Database and Mag-Iran. We also assessed grey literature, that is, national studies and papers presented at relevant Iranian congresses. All data collected from studies were converted to daily servings (S/D). Mean and standard deviations of the included results were combined by performing meta-analysis with a random effects model. The I2 test was used to compute heterogeneity. Egger’s test was used to assess publication bias. Results: Ten studies with 67 093 children were included in this review. The meta-analysis demonstrated that the highest consumption of processed foods belonged to the sugars and sweets group with 8.01 S/D, followed by oils, and biscuits and cakes with 5.58 S/D and 3.33 S/D, respectively. Conclusion: Given the high consumption of less healthy processed foods, robust policies to support healthy eating and help improve Iranian children’s food environment are recommended.

Background: The prevalence of allergic rhinitis in the world is 10-15%, and it is currently the most common chronic disease among children. There is no comprehensive statistics about the prevalence of allergic rhinitis among Iranian children, therefore, this systematic review and metaanalysis was conducted to evaluate the prevalence of allergic rhinitis among the Iranian children. Methods: The present study was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. The data was collected using key words including allergic rhinitis, prevalence, epidemiology, child OR children, pediatrics and Iran, in international databases including PubMed, Scopus, Web of Science, Cochrane, Embase, and three national databases including Magiran, Iran Medex, and Scientific Information Databank (SID) till December 2018. The STROBE checklist was used for quality assessment. The data were analyzed using STATA software version 12.1. Results: The prevalence of allergic rhinitis in children and adolescents were 18% (99.7% CI: 10-28% with publication bias of 0.174) and 25% (99.8% CI: 17-33 with publication bias of 0.617) respectively. The prevalence of allergic rhinitis in males was estimated to be 27% (99.4% CI: 17-36) with publication bias of 0.538 and in females was 23% (99.4% CI: 14-31) with publication bias of 0.926. Conclusion: The prevalence of allergic rhinitis is approximately high among Iranian children and adolescents; thus, educational strategies should be considered to decrease the prevalence of this disease in Iran.

ObjectiveThis living systematic review aims to provide a timely, rigorous and continuously updated summary about the impact of overweight or obesity as a prognostic factor for severity and mortality in patients with COVID-19. DesignThis is a protocol of a living systematic review.Data sourcesWe will conduct searches in MEDLINE/PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), grey literature and in a centralized repository in L·OVE (Living OVerview of Evidence). L·OVE is a platform that maps PICO questions to evidence from Epistemonikos database. In response to the COVID-19 emergency, L·OVE was adapted to expand the range of evidence it covers and customised to group all COVID-19 evidence in one place. The search will cover the period until the day before submission to a journal.Eligibility criteria for selecting studies and methods We adapted an already published common protocol for multiple parallel systematic reviews to the specificities of this question. We will include all primary studies that assess patients with confirmed or suspected infection with SARS-CoV-2 and inform the relation of overweight or obesity with death or disease severity. Two reviewers will independently screen each study for eligibility, extract data, and assess the risk of bias. We will pool the results using meta-analysis and will apply the GRADE system to assess the certainty of the evidence for each outcome. A living, web-based version of this review will be openly available during the COVID-19 pandemic. We will resubmit it every time the conclusions change or whenever there are substantial updates.

Background: Unsafe behaviors are the cause of 80% of accidents. However, there has also been no worldwide review and meta-analysis of the prevalence of workers’ unsafe behaviors. Therefore, the present study aimed to investigate and estimate the prevalence of unsafe behaviors among Iranian workers using a systematic review and meta-analysis study. Methods: This systematic review and meta-analysis were conducted from Nov to Dec 2018. The researchers searched Medline/PubMed, Scopus, Embase, Science Direct, and Google Scholar for international articles and four Iranian databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) for Persian articles. The method of reporting this study was based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) checklist. Results: Overall, 235 articles from databases were imported to EndNote library. Final screening of the included studies produced a total of 38 studies. Based on the random-effect model, the prevalence of total unsafe behaviors, nonuse or inappropriate use of personal protective equipment, and inappropriate work posture was 40.37% (CI 95% = 35.8-44.9), 27.79% (CI 95% = 21.2-34.3), and 14.87% (CI 95% = 10.7-18.9). There was no statistically significant relationship between unsafe behaviors and mean age, mean of work experiences, and year of study. Conclusion: The prevalence of unsafe behaviors among Iranian workers was relatively high and the most common behaviors were non-use or inappropriate use of PPE; one of the most important causes for this behavior is lack of training, inappropriate working conditions, and lack of positive attitude towards safety. Therefore, further studied are required to investigate the causes of these unsafe behaviors.

Background. Asthma is an important reason for hospitalization in children aged under five years. Information about the current status of asthma in Iranian children can help the Iranian health sector plan carefully and prevent asthma incidence by educating the families. The present systematic review and meta-analysis is aimed at estimating asthma prevalence in Iranian children and adolescents. Method. Data were found using keywords such as prevalence, epidemiology, asthma, adolescent, children, pediatrics, Iran in Web of Science, Scopus, PubMed, Cochrane, and Embase databases. Three national databases, including Magiran, Barakat Pharmed Co (Iran medex), and Scientific Information Databank (SID) were searched until 1 October 2020. Cross-sectional and original studies were included in the study, and then, quality assessment was done using the National Institutes of Health’s Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. A pooled estimated prevalence of asthma was calculated using Der Simonian-Laird random model. Egger’s test was used to evaluate publication bias. The data were analyzed using the STATA software version 16. Results. 30 studies were selected and investigated. The prevalence of asthma in children and adolescents was 6% and 8%, and the prevalence in boys and girls was 9% and 8%, respectively. Among the asthma symptoms, wheezing had the most prevalence (17% in children and 19% in adolescents) and sleep disturbance had the lowest prevalence (6% in children and 6% in adolescents). Conclusion. The prevalence of asthma in Iranian children and adolescents is lower than in the world. Existing strategies should be pursued followed. Also, guidelines for asthma control and prevention should be considered in the future.

IntroductionMid-upper arm circumference (MUAC) has been suggested as an alternative screening tool to identify overweight and obesity in children and adolescents. Several studies have examined the diagnostic performance of MUAC to identify overweight and obesity in children and adolescents. However, the existing literature shows a considerable variability in measures of diagnostic performance and hence makes it difficult to direct clinical and public health practice. Therefore, this systematic review and meta-analysis aimed to synthesise evidence on the performance of MUAC to identify overweight and obesity in children and adolescents.Methods and analysisA systematic search of databases including PubMed, EMBASE, SCOPUS, Cochrane Database of Systematic Reviews, Cochrane CENTRAL, Web of Science, CINAHL and PsycINFO will be conducted. The search will cover all studies until 1 April 2021. Grey literature will also be retrieved from Google Scholar. Titles and abstracts will be screened by two independent reviewers. The Quality Assessment of Diagnostic Accuracy Studies 2 tool will be used to assess the risk of bias and clinical applicability of each study. To assess possible publication bias, we will use Deeks’ funnel plot. We will investigate the sources of heterogeneity by visual inspection of the paired forest plots and summary receiver operating characteristic plots. The pooled summary statistics for the area under the curve, sensitivities, specificities, likelihood ratios and diagnostic ORs with 95% CI will be reported.Ethics and disseminationThe underlying study is based on published articles thus does not require ethical approval. The findings of the systematic review and meta-analysis will be published in a peer-reviewed journal and disseminated in different scientific conferences and seminars.PROSPERO registration numberCRD42020183148.

Abstract Background Cardiovascular disease is the cause of more than 50% of mortalities globally, and this rate has grown by 8.6% since the 60 s. One of the risk factors associated with cardiovascular disease and its resulting mortality rate is the metabolic syndrome. Different studies have reported inconsistent rates for the metabolic syndrome. However, no comprehensive study has been conducted to combine the results of existing studies. Thus, the present study was performed with the aim of determining the prevalence of metabolic syndrome among cardiovascular patients in Iran through a systematic review and meta-analysis. Method : In this review study, the Scientific Information Database, Google Scholar, Science Direct, Scopus, PubMed, and Web of Science (ISI), databases were searched from January 2005 and until May 2020, to identify and extract related articles. To conduct the analysis, a random effects model was used, and the heterogeneity of the studies was examined using the I2 index. Data analysis was performed within Comprehensive Meta-Analysis (version 2) software. Results The prevalence of metabolic syndrome in cardiovascular patients in Iran in the 27 papers examined with a sample size of 44,735 patients was 34.2% (95% CI: 26.8–42.6%). A sensitivity analysis was performed to ensure the stability of the results, these results show that by omitting the prevalence from each study, the overall prevalence (34.2%) does not change significantly. the highest prevalence of metabolic syndrome in studies conducted in the period between 2015 and 2020, and this was reported as 55.3 (95% CI: 47.9–62.3) and the highest prevalence of metabolic syndrome in studies conducted in the methods of diagnosis IDF, and the rate was reported as 48 (95% CI: 36.5–59.8). based on meta-regression as the year of research increased, the prevalence of metabolic syndrome in cardiovascular patients in Iran also increased. However, with the increase in sample size, this prevalence decreased (p < 0.05). Conclusions The results of this study indicate that metabolic syndrome is high in cardiovascular patients in Iran. Accordingly, by understanding its etiology and supervision at all levels, suitable solutions could be offered by providing feedback to hospitals.

Human Cystic Echinococcosis

Human cystic echinococcosis (HCE), a zoonotic infection of the larval stage ofEchinococcus granulosus, has high effect on public health in human population all around the world. Iran is one of the most important endemic areas in the Middle East. This systematic review and meta-analysis was performed to evaluate the seroprevalence of HCE in Iranian population. An electronic search for articles from 1985 until April 2015 was performed using data bases PubMed, Scopus, Google Scholar, Magiran, IranMedex, Iran Doc, and Scientific Information Database (SID) both in English and in Persian. A random-effects meta-analysis was used to combine results from individual studies. The information was analyzed by STATA version 11.1. A total of 33 articles met our eligibility criteria and were included in a meta-analysis. The pooled estimate of the prevalence of HCE based on random-effects model was estimated 6.0% (95% CI: 4.0%, 7.0%). The prevalence of the disease significantly increased with age and prevalence rate in males was significantly lower than females (p<0.001). The using of CIE or CCIEP method was also significantly greater than the other methods (p<0.001). There was a publication bias in prevalence of studies. HCE is highly prevalent in Iran. Public education for preventive strategies and finally reducing transmission of the parasite and infection in population is needed.

Background: Esophageal Cancer (EC) is the eighth most common cancer in terms of incidence. Despite various studies, there is no general estimate of EC incidence in Iran. Therefore, the present study is conducted to evaluate the incidence rates of EC in Iran. Method: A systematic search was conducted on all published studies of EC incidence using Medline/PubMed, Scopus, Web of sciences, Google scholar, and four Iranian databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) until November 2017. This systematic review was done according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA). Result: The database, grey literature searches, and hand searching yielded 346 potentially relevant studies. A total of 22 studies were included. The results of the random effect model were demonstrated the age-standardized rate (ASR) of EC was 25.05, 95% CI (20.84 to 29.26) among males and 22.93 95 % CI (18.97-26.88) among females. Conclusion: In comparison to other geographical locations, the incidence of EC is higher in Iran. However, organized system for collecting data of cancer is required to specify the incidence and trend of EC in Iran.

Purpose The purpose of this paper (systematic review and meta-analysis) is to synthesize and analyze studies that assessed Iranian hospital efficiency. Design/methodology/approach A systematic literature search was conducted using both international (the Institute for Scientific Information, Scopus and PubMed) and Iranian scientific (Magiran, IranMedex and Scientific Information Database) databases. The review included original studies that used the Pabon Lasso Model to examine Iranian hospital performance, published in Persian or English. A self-administered checklist was used to collect data. In total, 12 questions were used for quality assessment. Findings In total, 34 studies met our inclusion criteria. The fixed-effects meta-analysis indicated that 19.2 percent (95% confidence interval (CI): 15.6–23.2 percent) of hospitals were in Zone 1 (poor performance: low bed turnover rate (BTR) and bed occupancy rate (BOR) and high average hospital stay (ALoS)), 23.7 percent (95% CI: 20.1–27.8 percent) were in Zone 2, 31.7 percent (95% CI: 27.7–36 percent) in Zone 3 (good performance: high BTR and BOR and low ALoS) and 25.4 percent (95% CI: 21.7–29.5 percent) in Zone 4. Practical implications Results help Iranian health policymakers to understand hospital performance, which, in turn, may lead to promoting greater awareness and policy attention to improve Iranian hospital efficiency. Originality/value This study indicated that most Iranian hospitals had sub-optimal performance. Further studies are required to understand factors that explain the country’s hospital inefficiency.
