METHODS: This descriptive and retrospective study was conducted within a 10-year period (2008-2017), in which all articles published in five specialized Iranian journals of environmental health engineering were reviewed using a researcher-made checklist. The information collected in the checklist included: the year of publication, number of issues and articles, information about the status of authors' participation in terms of number of authors, sex, institutional affiliation, country, continents, and research centers. Descriptive and inferential statistics such as index of dispersion, measures of central tendency, and Chi-square and t tests were used to statistically analyze the data. Besides, VOSviewer software was used to visualize the data.
RESULTS: The review of 1276 articles published in 102 issues of the five journals of environmental health engineering in Iran showed that 184 articles were written with the participation of researchers from other countries. Most articles with the participation of international authors during the last decade were published in 2014. Chi-square test indicated a significant difference in the publication of these articles within 2014-2015 than other years (P = 0.001). Among the five journals, the best participation of international researchers was observed in J Environ Health Sci Engineer (168 articles, 91.3%). Considering the number of joint articles with Iran, the top continents were Asia, Europe, and Africa each with 117, 52, and 32 articles, respectively. India, Turkey, and Malaysia had the highest level of cooperation with Iranian researchers with 53, 16, and 14 articles, respectively. 637 authors contributed in 184 articles, of whom 469 (73.6%) were male and 121 (18.9%) were female. T test was used to compare the mean number of male and female authors in the articles with or without the participation of international researchers, which showed no significant difference.
CONCLUSION: International contribution of researchers in compilation of specialized environmental health articles was good. Given the low level of cooperation between researchers from developed European and American countries and their Iranian counterparts, it seems necessary to adopt different methods to attract more collaboration from researchers working in developed countries considering their significant role in health-related areas.
RESULTS: In this study, 774 articles related to 114 issues of 3 specialized environmental health journals were reviewed. A review of 774 articles showed that 80 articles (10.3%) were published in the field of nanotechnologies. Out of 80 articles published in the field of nanotechnology, 66 articles (82.5%) were published on the subject of water, 9 articles (11.3%) on wastewater and 5 articles (6.2%) on air pollution. Subject review of articles showed that articles using carbon nanotubes to remove natural organic pollutants, surfactants, hydroxybenzenes, phenol, dimethyl phthalates, use of titanium dioxide nanoparticles, iron-magnesium nanoparticles for wastewater treatment, Silver nanoparticles were used to remove air pollution. The results showed that published articles on nanotechnology in the field of environmental health were few.
METHODS: This systematic review study was performed to determine the types of nutrients in breads consumed in Iran by searching reputable international databases including Scopus and Google scholar, PubMed, Science direct, ISI (Web of Science). Data were collected according to inclusion and exclusion criteria and by searching for relevant keywords, emphasizing the types of nutrients in breads consumed in Iran. Qualitative data were collected using the standard PRISMA checklist (preferential reporting items for systematic reviews and meta-analysis). After verifying the quality of the articles, the information was entered into a checklist such as the name of the first author and year of publication of the research, type of study, number of samples, type of nutrition, type of bread and amount of nutrition measured.
RESULTS: After reviewing the information and quality of articles, 10 articles were qualified for systematic review. The review of the articles showed that different breads were experimented, including: Sangak, Barbari, Taftoon, Lavash, French and local bread. The highest number of experimented bread samples was Sangak. Examination of the articles showed that 6 nutrients were experimented in different breads such as Fe, K, Mg, Ca, Cu and Zn. The highest number of experimented in breads was related to the amount of Zn (13 times) and Cu (10 times), respectively. The results of quality assessment of articles showed that most of the studies were of good quality. The results of articles on the amount of nutrients measured in different breads showed that only in two articles the amount of nutrients was reported to be desirable. In most articles, the amount of nutrients in breads was reported to be lower or higher than standard.
CONCLUSION: The results of this study showed that the concentration of nutrients in most articles was undesirable. It is suggested that optimal methods of enrichment of breads and flours be done with interdisciplinary cooperation between food hygiene, environmental health, nutrition, farmers and bakers. It is recommended that food hygiene and environmental health researchers investigate other nutrients (including phosphorus, selenium, manganese, boron and molybdenum) in breads and other staple foods used by people to constructive and practical measures to increase public health.
METHODS: This cross-sectional descriptive study was performed on all published articles in five Iranian environmental health journals and three international environmental health journals that are among the top 5% and 10% based on SNIP, emphasizing the issue of food. Our data were collected by searching relevant keywords in the articles published during the years (2008-2021), with emphasis on food hygiene. In the checklist, journal and articles information was collected by year of publication, a number of articles, information on authors' participation status in terms of number, gender, organizational affiliation, country and continents, and research centers according to authors' authorship. Statistical analysis of data was performed using descriptive and inferential statistical indices. VOSviewer software was also used to visualize the data.
RESULTS: In Iranian environmental health journals, out of 2305 articles (7.3%) and out of 6898 articles in international environmental health journals (2.4%) dealt with food hygiene. Food hygiene articles were divided into seven categories, with the largest number of articles on aquatic and agricultural products each with a frequency of 48 articles. Articles related to heavy metals in food were provided by 30.81%. In this study, out of 150 articles, 15 articles were written with the participation of 30 authors from seven continents (Asia, America, and Europe), most of which were from Asia and India. In international environmental health journals, among the main research topics in articles related to food hygiene, the highest number (52.5%) was related to a determination about pollution such as heavy metal concentrations in food.
CONCLUSIONS: Articles published in Iranian and international environmental health journals about food hygiene were limited. According to the increasing prevalence of foodborne illnesses, especially in recent decades, and the importance of paying attention to food hygiene, more targeted studies are needed.
