Obesity represents a major global public health problem. In the past few decades the prevalence of obesity has increased worldwide. In 2016, an estimated 1.9 billion adults were overweight; of these more than 650 million were obese. There is an urgent need for potential solutions and deeper understanding of the risk factors responsible for obesity. A bibliometric analysis study was designed to provide a comprehensive overview of top 100 most cited studies on obesity indexed in Web of Science database. The online search was conducted on June 6, 2021 using the keywords “Obesity” OR “Obese” OR “Overweight” in title filed with no limitations on document types or languages. The top 100 cited studies were selected in descending order based on number of citations. The obtained data were imported in to Microsoft Excel 2019 to extract the basic information such as title, authors name, journal name, year of publication and total citations. In addition, the data were also imported in to HistCite™ for further citation analysis, and VOSviewer software for windows to plot the data for network visualization mapping. The initial search retrieved a total of 167,553 documents on obesity. Of the total retrieved documents, only top 100 most cited studies on obesity were included for further analysis. These studies were published from 1982 to 2017 in English language. Most of the studies were published as an article (n = 84). The highly cited study on obesity was “Establishing a standard definition for child overweight and obesity worldwide: international survey” published in BMJ-British Medical Journal (Impact Factor 39.890, Incites Journal Citation Reports, 2021) in 2000 cited 10,543 times. The average number of citations per study was 2,947.22 (ranging from 1,566 to 10,543 citations). Two studies had more than 10,000 citations. A total of 2,272 authors from 111 countries were involved. The most prolific author was Flegal KM authored 14 studies with 53,558 citations. The highly active country in obesity research was United States of America. The included studies were published in 33 journals. The most attractive journal was JAMA-Journal of the American Medical Association (Impact Factor 56.272) published 17 studies and cited globally 51,853 times.

Microplastics pollution of our environment has seen major data reporting in the last decade. Microplastics produce harmful effects on marine organisms and in humans. In this scientometric study, we have evaluated literature between years 2011-2019. Our data shows that publications counts are increasing with an important role for China and its funding agencies in the field. A majority of research articles were published by authors affiliated with Chinese Academy of Sciences. Journals ‘Marine Pollution Bulletin’ and ‘Environmental Pollution’ were identified as important Journals with 273 and 185 research publications, respectively. We have also identified the upcoming research trend and shift from microplastics presence in water to microplastics presence in air. A major shift is observed in year 2017 and United Kingdom is leading this field with 11 publications with top authors affiliated to University of Plymouth. Interestingly, the Journal Environmental Pollution has published the most research articles (~20%). Our co-authorship analysis demonstrated that China (and it’s institutions and authors) is the most collaborative country followed by the United States, together forming top cluster with a link strength of 42. Finally, our analysis provides information about prospective research and emerging trends that can be explored in the coming years.

Public Health Surveillance Systems in the Eastern Mediterranean Region: a Bibliometric Analysis of Scientific Literature (Preprint)

BACKGROUND The two main general categories of surveillance include indicator-based surveillance and event or case-based surveillance. However, new and novel approaches in surveillance are in a constant state of high and immediate demand to tackle unexpected health challenges in a timely manner directly, and address community health concerns. Bibliometric analysis of scientific literature on surveillance helps foster an understanding of the scientific development and thus potentially supports future development directions. OBJECTIVE To illustrate the scientific production, quantify the scholarly impact, and highlight the characteristics of publications on public health surveillance (PHS) in the Eastern Mediterranean Region (EMR) over the last decade. METHODS We performed a Scopus search using keywords relating to PHS or its disciplines, cross referenced with EMR countries, from 2011-July 2021. Data were exported and analyzed using Microsoft Excel and VOSviewer. Quality of Journals was determined using SCImago journal rank. RESULTS We retrieved 1,987 documents, of which 97% were articles or reviews. There was an incremental increase in the number of publications (exponential growth, R2=0.80) over the last decade. Publications were mostly affiliated with Iran (N=501, 25%), United States (N=468, 24%), Pakistan (N=243, 12%), Egypt (N=224, 11%) and Saudi Arabia (N=209, 11%). However, Iran only had links with 40 other countries (total link strength 164) and the biggest collaborator from the EMR was Egypt, with 67 links (total link strength 402). Within the other EMR countries, only Morocco, Lebanon, and Jordan produced ≥79 publications in the 10-year period. Most publications (N=1,551, 78%), were affiliated with EMR universities. Most Journals were categorized as medical journals, and the Eastern Mediterranean Health Journal (SJR 0.442) published the most. Retrieved documents had an average of 18.4 citations/document, and an h-index of 66. The top three most cited documents were from the Global Burden of Diseases study. We found 70 high frequency terms, occurring ≥10 times in author keywords, connected in three cluster. COVID-19, SARS-COV-2 and pandemic represent the most recent 2020 cluster. CONCLUSIONS This is the first study to scholarly quantify the published literature on PHS and its disciplines in the EMR. It provides an analysis of the scientific research, with evidence-based descriptions and visualizations of research output, also shedding light on the gaps in research.
