The 100 top-cited articles on childhood obesity: a bibliometric analysis

Background:Childhood obesity(CHO)is a serious global health challenge affecting both developed and developing nations.The feats attained in addressing this global health challenge can be reflected through the top-cited studies.The study’s aim was to analyze the features of the 100 top-cited articles concerning CHO.Methods:We used a bibliometric analysis,and searched for relevant articles from the Web of Science(December 1,2021),using an appropriate keyword search-strategy((child OR childhood OR children OR adolescent)AND(obese OR obesity OR overweight)).The retrieved documents were analysed based on the citation number,publication year,authorship,institution,journal and country.The analyses were performed mainly by the Bibliometrix application(using R-studio cloud)and HistCite.Results:The 100 top-cited articles were published between 1976 and 2018,their citations ranged from 365 to 10789,with a mean citation of 1146.2 and 31 studies had more than 1000 citations.The articles were published in 31 journals,with the“Pediatrics”journal having the most publications(n=18).The studies were from 12 countries,with the most-productive being the USA(n=68),followed by the United Kingdom(n=12)and France(n=3).The leading institution was the University of Bristol(n=8),while Dietz WH(n=12),and Flegal KM(n=8)were the most productive authors.The most common research fields covered by these articles were;“General Internal Medicine”(n=34),“Pediatrics”(n=29),and“Nutrition Dietetics”(n=18).The study noted significant correlations between the total article citation and the number of authors(R=0.203),countries involved(R=0.407),institutions(R=0.407),and the publication year(R=0.847),all with P<0.001.Conclusions:Through these top-cited articles,this analysis provides discernment into the historical advancements,including the prime roles performed by various stakeholders in addressing the issue of CHO.However,Asian countries’contribution is not adequately reflected in these articles,and thus more focus and funding for CHO research are needed for effectual prevention and control.

Bibliometric analysis of top 100 cited articles in nonalcoholic fatty liver disease research

AIM To identify and assess the research situation of top 100 cited articles in nonalcoholic fatty liver disease(NAFl D).METHODS The global scientific research articles in the science Citation Index-Expanded relevant to NAFl D were retrieved and listed according to their citation times from the most to the least. The 100 most frequently cited original articles were selected to systematically evaluate their bibliometric parameters including times cited, publication year, journals, subject categories, and the highly related concepts of NAFl D, which reflected the history and current situation, publication distribution of leading countries and institutes as well as the research hotspots of NAFl D.RESULTS Top 100 cited articles in NAFl D were published from 1965 to 2015 with a citation ranging of 227 to 2151 times since publication, in which the United states was the most predominant country and Mayo Clin was the most productive institution. The majority of the top 100 cited articles were concentrated in s CI subject category of Gastroenterology and Hepatology. Hepatology and Gastroenterology is the top journal that published over half 100 top-cited articles. The significant peak of top cited articles present in the first half of the 2000 s while the highest mean number of citation presents in first half of the 1980 s. In addition, concepts related to pathology characteristics, epidemiology and medicalization, metabolic syndrome and its combination of symptoms including insulin resistance, biomarkersof lipid metabolism and obesity are listed as the highly related concepts.CONCLUSION The 100 top-cited articles marked with the leading countries, institutions, journals, hotspots and development trend in NAFl D field that could provide the foundation for further investigations.
