A bibliometric analysis of income and cardiovascular disease

Abstract

Background: Income is 1 of the socio-economic indicators and could directly influence the health outcomes of cardiovascular disease (CVD). The relationship between income and CVD has attracted more and more scholars’ attention in the past 20 years. Methods: To study the current research dynamics of this field, a bibliometric analysis was conducted to evaluate the publications from 1990 to 2018 based on the Science Citation Index Expanded database. By using the Derwent Date Analyzer software, the following aspects were explored: historical trend of the topic; the main contributor: leading countries, leading institutions, leading research areas and journals; representative authors; most frequently used keywords; most cited papers. Results: The USA ranked first in this field, followed by UK and Canada in terms of number of publications. As for institutions, Harvard University took the leading place in the number of publications, as well as the h-index. Plos One had the most publications and “health” was the most frequent used keyword. The leading research area was “public environmental occupational health”. Conclusions: In conclusion, the elderly, the children and the puerpera were the main study population in this field and “disease prevention” was the main study direction. The most concerned health issues in this field were “obesity” and “diet”. There might be a lack of articles that explore the associations between income and CVD with a global perspective. Articles on this content are urgently warranted.

Current Status and Trends of Research on Anthracycline-Induced Cardiotoxicity from 2002 to 2021: A Twenty-Year Bibliometric and Visualization Analysis

“…Keywords and cocited references are usually the focus of bibliometric analysis. Their co-occurrence networks and burst terms could reflect the developmental process and hot frontiers of a specific research field [ 24 , 25 ].…”

“…Figure 5(a) exhibits the number of publications of the top 10 productive authors and their H-index. Simunek Tomas from Charles University contributed the most papers (n = 42), followed by Ky Bonnie from the University of Pennsylvania (n = 41) and Sterba Martin from Charles University (n = 39), while Lipshultz Steven E. from the State University of New York owned the highest H -index (27), followed by van Dalen Elvira C. from the Princess Máxima Center for Pediatric Oncology (25) and Cardinale Daniela from the European Institute of Oncology (25). More detailed information concerning each author's publications over time is shown in Figure 5 3 Oxidative Medicine and Cellular Longevity indicates the number of publications.…”

Global mapping of research trends on antibacterial activity of green silver nanoparticles

“…Author keywords could identify the central emphasis of a research article and pinpoint a certain pattern of the research based on analysing the most frequent keywords. The bibliometric analysis through author keywords has been proved to be an effective method in revealing the sci-entific research trends and hotspots (39). The most frequently used keywords in the field are represented in Fig 4a . In the same vein, Fig.…”

“…Bibliometric analysis is an important statistical tool that quantitatively evaluates the scientific contribution of an author, institution and country in a particular field over the years (36,37). The bibliometric analysis offers a quantitative review of literature in any field of research based on the citation frequency of the published research (38,39). It is a statistical gauge that can measure the influence of research outputs within a particular subject or research field that represents the research hot spots and trends (40).…”

Recent Trends in Sedentary Time: A Systematic Literature Review

“…However, there is little information available in the literature that presents a distinct perspective by conducting bibliometric analysis to summarize the overall view of the sedentary time research field. Bibliometric analysis is widely used as a valid tool to quantitatively evaluate the distribution of active countries, institutions, authors, and collaborations, and find the hotspots and the research trends in various research areas such as chemistry [33], mechanical engineering [55,56], energy [57], optics [58], software engineering [59], medicine [60][61][62], health [63], economics [64,65], art [66], management [67], urban planning [68], social work [69], etc.…”
