Evaluating the impacts of environmental factors and compliance with health guidelines on the rate and trend in Covid-19 infection in Alborz province, 2019
Parvane Dowlati, Hatam Godini, Abbas Moghimbeigi, Yahya Khosravi,
Volume 16, Issue 1 (6-2023)
Abstract
Background and Objective: In this research, considering the importance of the adverse effects of the Covid-19 disease and identifying the environmental factors involved in its outbreak, the effects of environmental factors and compliance with health guidelines on outbreak and mortality of Covid-19 have been evaluated.
Materials and Methods: This research was a descriptive-analytical study on confirmed patients with Covid-19 in Alborz province in 2019. In this study, outbreak rate and death due to Covid-19, compliance with health guidelines, air pollutants concentrations, air pollution indicators, and the meteorological conditions of Alborz province were daily collected for 2019. All data were analyzed in IBM SPSS Statistics v26 software with Pearson, Spearman, Kruskal-Wallis, one-way variance ANOVA analysis tests, and negative binomial regression statistical models.
Results: The results of the regression model showed that in the mortality rate due to Covid-19, the variables of average temperature(p=0.042), humidity(p=0.048), rate of Covid-19 infection(p=0.001), and compliance with health guidelines(p=0.007) are significant. However, in the model of the rate of infection with Covid-19, only compliance with health guidelines(p=0.001) was significant. Pearson's and Spearman's correlation coefficients for infection rate, compliance with health guidelines, wind speed, and concentrations of carbon monoxide, PM2.5, and SO2 with the death rate due to corona, were 0.575, -0.411, -0.206, 0.211, 0.114 and -0.158.
Conclusion: The results showed that in addition to compliance with health guidelines, some atmospheric factors and air pollutants also impact the rate of infection and mortality caused by Covid-19.
 

The role of environmental health in the prevention and control of diseases related to environmental factors in Iran: a scientometric study
Ali Hamidi, Maryam Ravanipour, Masoumeh Ravanipour,
Volume 17, Issue 2 (9-2024)
Abstract
Background and Objective: Scientometrics is used to identify existing study gaps, discover the future research directions, investigate fundamental trends and implement the necessary policies in a specific field of knowledge. Considering the key role of environmental factors in the health trends and the varyingburden of diseases in the country, this study was conducted with the aim of performing scientometric analysis of the role of environmental health in the prevention and control of diseases related to environmental factors in Iran.
Materials and Methods: Bibliographic information related to scientific documents indexed in the Web of Science database until September 12, 2022, was analyzed and visualized using Citespace and Biblioshiny software.
Results: A total of 1,212 documents were retrieved. These documents were published in 629 sources with the participation of 8,461 authors. The average publication year of the documents was 2010. The top three ranks of organizational affiliations were as follows: Tehran University of Medical Sciences (747 documents), Isfahan University of Medical Sciences (436 documents), and Shahid Beheshti University of Medical Sciences (393 documents). Iran's cooperation network with other countries indicates substantial joint researchbetween Iran and the main countries in this network. Over time, the co-occurrence network of keywords has evolved from outcomes (such as cardiovascular diseases, cancers, etc.) to environmental exposure factors, especially air pollutants, heavy metals, and food-borne pathogens factors. Risk assessment has also been a category of interest in recent years.
Conclusion: Scientometric analysis showed that environmental health studies in prevention and control of diseases related to environmental factors in Iran are young and still progressing. In the early years, studies were mainly focused on diseases as an outcome, while in recent years, they have focused more on exposure factors or environmental pathogens. It is suggested that the future studies based on the retrieved keywords should be more mission-oriented and the priority of solving the problems of environmental pollutants affecting people's health in the country based on the extent and scope of the problems of each province should be considered by policy makers and researchers.
