Background: Bibliometric analysis of the journal is a method to assess the research impact or research influence of that journal. This information can also be used to evaluate the influence/performance of a researcher and to provide a comparison between researchers. This work was aimed at performing bibliometric analysis of Indian Journal of Endocrinology and Metabolism (IJEM). Materials and Methods: The publications of year 2011-12 of IJEM were analyzed. Total number of articles published, type of articles, their authorship, and the coverage of various subspecialties was studied. The publications were also classified as Indian or foreign, from endocrine or nonendocrine departments and from academic or nonacademic institutions according to the institution of first author. Results and Conclusions: A total of 10 main issues and 7 supplementary issues were published in IJEM in year 2011 and 2012. These included a total of 605 publications, which depict a dramatic increase in the number of publications in last 2 years as compared to the previous years. Taking collectively, review articles were published in majority. Maximum number of articles was dealing with pancreas and metabolic disorders followed by thyroid. Other endocrine organs were given almost similar importance. Publications were largely originating from endocrine departments and from academic institutions. Although maximum number of articles were from India, but the publications from other countries are also on an increase. Thus, the widespread coverage of this journal suggests that IJEM has begun to represent global face of Indian endocrinology.

   Introduction Top

Science is a driving force of our modern society. Particularly excellent scientific work is the cradle of breakthroughs in our knowledge of the world. Communication, that is, exchange of research results, is the driving force in science. Publications are not the only, but also certainly very important elements in this knowledge exchange process. Therefore, evaluation of scientific research is crucial. There are many methods to evaluate scientific research and bibliometric analysis is one of them.

Bibliometric analysis is defined as organization, classification, and quantitative evaluation of publication pattern of macrocommunication along with their authorships by mathematical and statistical calculations. [1]

Evaluative bibliometrics seeks to assess the impact of scientific output in the context of other published science and usually compares the relative scientific contributions of research groups or institutions. It can indicate the impact of a paper, a research field, and of a set of researchers. [2] It also helps in accessing the quality of research output of universities and thus helps the policy makers to allocate research funding on the basis of the assessment results. [3] It helps the researchers to decide about where to get their research published. Larger units, such as schools, colleges, and universities use bibliometrics as one tool to demonstrate how successful they are at getting published and to assess the impact of their research effort. Thus, this type of analysis provides useful indicators of scientific productivity, trends, the emphasis of research in various facets, and researchers' preferences for publication. [4]

This article aims at performing bibliometric analysis of the Indian Journal of Endocrinology and Metabolism (IJEM). This journal is official journal of the endocrine society which was formed in 1971. The journal has been available online since 2007. It has established itself as a leading technical journal in India in the field of endocrinology. It is a bimonthly journal that publishes technical and clinical studies related to health, ethical, and social issues in field of diabetes, endocrinology, and metabolism.

   Materials and Methods Top

IJEM issues of last 2 years (2011 and 2012) available online were taken for analyzing the publication trends in this journal. The data were derived from the web site of the journal, which gives link to the previous issues.

The articles published were analyzed for the type of the articles (editorial, review article, original article, brief communication, case report, letter to the editor, endocrinology around the world, endocrinology, and arts and miscellaneous). Total number of publications in 2011-12 was also compared against publications in 2007-10. Unpaired t test was applied for statistical analysis.

For the purpose of analysis, the articles were broadly divided into nine major groups consisting of pituitary, thyroid, parathyroid, pancreas and metabolic disorders, gonads, renal, and adrenal endocrinology and general endocrinology.

The articles were later categorized as Indian or foreign, from academic or nonacademic institutions and from endocrine or nonendocrine departments, depending upon the institution of the first author.

   Results Top

In year 2011-12, a total of 10 main issues and 7 supplementary issues were published in IJEM. These included a total of 605 publications, comprising of 38 editorials, 165 review articles, 95 original articles, 101 brief communications, 93 case reports, 95 letters to the editor, 4 articles on endocrinology around the world, 3 articles on endocrinology and arts, and 11 miscellaneous articles [Table 1].

Total number of articles published increased from 165 in 2011 to 440 in year 2012. This increase was seen in all categories of articles except endocrinology around the world. Articles on endocrinology around the world were published in year 2011, but not in year 2012. In year 2012, articles on endocrinology and arts and some miscellaneous articles (South Asian guidelines for management of endocrine disorders in Ramadan, orations and abstracts presented at ESCICON 2012) were also included. In both years, review articles formed the major chunk of the publications, followed by brief communications in 2012 and case reports in 2011. Research work was published as original articles, brief communications, case reports, and letters to the editor.

The total number of articles in 2011-12 was also compared with articles of 2007-10 [Table 2] and [Figure 1]. Total number of publications increased tremendously in years 2011 and 2012. Update articles and images have not been published in year 2011 and 2012. However, newer categories of articles have been included in these years like brief communications, letters to the editor, endocrinology around the world, endocrinology and arts, and some miscellaneous articles.

Statistical analysis of the mean number of articles published in 2007-10 and in 2011-12 reveals that there is a statistically significant increase (P = 0.007) in the publication number in 2011-12 [Table 3].

In year 2011, there were almost similar contributions from endocrine (48.48%) and nonendocrine (51.51%) departments. In 2012, publications from endocrine departments were much higher in number (56.03% vs. 43.96%). Taking together, endocrine departments contributed more (53.97%) as compared with nonendocrine departments (46.02%).

A considerable fraction of publications was from foreign countries (16.88%) in last 2 years. Taking individually, foreign publications were slightly more in 2012 as compared with 2011 (17.53% vs. 15.15%). From India, publications were obtained from almost every region of the country.

In year 2011, almost same number of publications was done by academic (52.72%) and nonacademic (47.27%) institutions, but in 2012, publications from academic institutes (65.83%) were almost double in number as compared with nonacademic institutes (34.16%). Taking collectively, the contribution from the academic institutes (62.25%) far exceeded the contribution from nonacademic institutions (37.74%).

However, the above three categorizations were based on the basis of institution of first author only.

   Discussion Top

In this article, we have tried to assess the publication trends of IJEM. The total number of articles published has increased significantly in last 2 years as compared with the previous 4 years. Maximum number of articles has been published in 2012. There is not only increase in the number of articles published, but also certain newer interesting categories of articles have also been introduced. Review articles were published in maximum number in IJEM, whereas according to bibliometric analysis of endocrinology articles published in Journal of the Association of Physicians of India (JAPI), original articles were published to the maximum. [5] The major chunk of the articles in IJEM is related to pancreas and metabolic disorders. All other endocrine glands have been given almost equal importance. But in volumes 11-13 of IJEM, the maximum number of articles were relating to metabolic bone diseases and parathyroid. [6] In JAPI also, maximum number of publications were regarding diabetes mellitus and metabolism, followed by bone disorders. [5]

A large fraction of the publications of IJEM in year 2011-12 have come from foreign countries. This suggests the increasing popularity of the journal in other countries also. From India, the publications have come from every region of the country. But in year 2007-2009, the scenario was not similar. Only very few contributions were received from foreign countries. [6] Endocrine departments have contributed much more to IJEM than nonendocrine departments in terms of publications, especially in year 2012. In relative terms, almost double publications have come from academic institutions as compared with nonacademic institutes in 2012. This is suggestive of the inadequate representation of private sector in IJEM. Similar picture was seen in IJEM publications in year 2007-2009. [6]

   Conclusions Top

The popularity of IJEM has increased manifolds in last 2 years, as suggested by increase in the quantity and quality of publications. It is growing at a rapid pace and is inviting wide spread submissions regarding endocrinology-related research. The articles cover a wide variety of topics of endocrinology. Not only are they from every part of the country, but also even other countries contributing immensely to this journal. Both endocrine and nonendocrine departments, academic and nonacademic institutions are important contributors to this journal. Thus, IJEM truly represents global face of Indian endocrinology.
