Insights
This study assessed global research on childhood type 1 diabetes (T1D). The USA leads in productivity, while Finland shows the highest impact, highlighting research gaps in developing nations.
Area of Science:
- Pediatric endocrinology and diabetes research.
- Bibliometrics and scientometrics.
Background:
- Scientometric studies are crucial for identifying research gaps and informing future scientific endeavors.
- Despite extensive research over two decades, a scientometric assessment of childhood onset type 1 diabetes (T1D) is lacking.
Purpose of the Study:
- To conduct a comprehensive scientometric assessment of the global research output concerning pediatric type 1 diabetes (T1D).
Main Methods:
- Analysis of publications on pediatric T1D from the Scopus database (2000-2019).
- Identification of leading countries, organizations, and authors based on productivity and impact.
- Examination of research trends, publication media, and characteristics of highly cited papers.
Main Results:
- Pediatric T1D research demonstrated significant growth, with 7.84% annual and 79.99% 10-year cumulative increases.
- The USA (29.76%) and UK (10.56%) were the most productive countries, while Finland (RCI 2.30) and UK (RCI 1.82) showed the highest relative citation impact.
- Research output is concentrated in 10 countries (82.67%), with limited contribution from developing nations, particularly in Southeast Asia.
Conclusions:
- The USA is the most productive country, and Finland is the most impactful in global pediatric T1D research.
- Significant disparities exist in research contributions, with a notable lack of engagement from developing countries despite a substantial disease burden.
Introduction:
Scientometric studies help scientists to identify research gaps and plan future research. There is no scientometric assessment of research on childhood onset type 1 diabetes (T1D), despite an intensive research in this field over the past 2 decades.
Aim Of The Study:
To provide a scientometric assessment of global research output in pediatric T1D.
Material And Methods:
Publications on pediatric T1D indexed in Scopus database over the 20-year period from 2000 to 2019 were examined. The most productive and impactful countries, organizations and authors, trends in research, the media of publications and characteristics of high cited publications were identified using appropriate bibliographic tools.
Results:
Pediatric T1D research registered 7.84% and 79.99% annual and 10-year cumulative growth and averaged 19.35 citations per paper (CPP). The field witnessed an uneven participation of 141 countries, wherein 82.67% of the global research output share came from top 10 countries. USA leads the ranking with 29.76% share, followed by UK (10.56%), Germany, Italy, Sweden and Australia (5.15% to 7.88%), and Poland, Finland, Canada and Denmark (3.04% to 4.24%). Five countries which registered relative citation index (RCI) higher than their group average of 1.63 were Finland (2.30), UK (1.82), Canada (1.77), Denmark and USA (1.74 each). The number of participating organizations and authors was 3627 and 5596 respectively.
Conclusions:
The USA and Finland are the most productive and the most impactful countries respectively in global pediatric T1D research. The contribution from developing countries especially from Southeast Asia is meager despite a large disease burden.

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
