Abstract
Background
There is a wide range of intellectual work written about health research, which has been shaped by the evolution of diseases. This study aims to identify the leading journals over the last 25 years (1990–2014) according to a wide range of bibliometric indicators.
Methods
The study develops a bibliometric overview of all the journals that are currently indexed in Web of Science (WoS) database in any of the four categories connected to health research. The work classifies health research in nine subfields: Public Health, Environmental and Occupational Health, Health Management and Economics, Health Promotion and Health Behavior, Epidemiology, Health Policy and Services, Medicine, Health Informatics, Engineering and Technology, and Primary Care.
Results
The results indicate a wide dispersion between categories being the American Journal of Epidemiology, Environmental Health Perspectives, American Journal of Public Health, and Social Science & Medicine, the journals that have received the highest number of citations over the last 25 years. According to other indicators such as the h-index and the citations per paper, some other journals such as the Annual Review of Public Health and Medical Care, obtain better results which show the wide diversity and profiles of outlets available in the scientific community. The results are grouped and studied according to the nine subfields in order to identify the leading journals in each specific sub discipline of health.
Conclusions
The work identifies the leading journals in health research through a bibliometric approach. The analysis shows a deep overview of the results of health journals. It is worth noting that many journals have entered the WoS database during the last years, in many cases to fill some specific niche that has emerged in the literature, although the most popular ones have been in the database for a long time.

Background
The scope of public health history is dynamic and has been shaped by the evolution of diseases. In the last decades, health research has moved from the study of sanitary reforms and the control of infectious diseases, to the study of the impact of epidemic and contagious diseases, and to the inclusion of social action initiatives taken in response of epidemic disasters. Thus, the scope of health research has been expanded and broadened from a range of intellectual disciplines including the study of health economics [1], and social and political relations of health [2]. These intellectual contributions have been well documented in a range of professional journals.
The oldest continuously published medical journal was introduced in 1812 by the Massachusetts Medical Society and was called The New England Journal of Medicine and Surgery and the Collateral Branches of Science, which in 1828 became The Boston Medical and Surgical Journal and later The New England Journal of Medicine. From that period of time many other medical associations and journals started to emerge including the Journal of the American Medical Association in 1883, Milbank Quarterly in 1923, Public Health Economics and Medical Care Abstracts (today’s Medical Care Research and Review) in 1944, Inquiry and Medical Care in 1963, Health Service Research in 1966, and Social Science and Medicine in 1967. Healthcare Financial Management and the International Journal of Health Services appeared in the 70’s, and also the Journal of Health Politics, Policy and Law, Health Care Management Review, Hospital and Health Services Administration, the Journal of Ambulatory Care Management and, and Health Care Financing Review. In the 80’s there was an explosion of new journals such as the Journal of Public Health Policy, Health Affairs, Advances in Health Economics and Health Services Research, Health Care Strategic Management, Frontier of Health Services Management, International Journal of Technology Assessment in Health Care, International Journal of Health Planning and Management, Health Care Financing Review, and the International Journal for Quality in Health Care. The first issue of the Journal of Health Services Research and Policy was published in 1996, and in the 2000s the Health Services and Outcomes Research Methodology appeared [3].
For this reason, there is a wide range of intellectual work written about health research and it is time to evaluate its development and main characteristics. Bibliometric analysis can help determine trends and patterns of publications within a research discipline, identifying the focus of research and the national and international strengths and biases [4, 5]. Over the course of the past few decades, several bibliometric analyses have been published regarding diverse topics in the literature of health research, including medicine and international health, where studies have tried to evaluate the contribution of different world regions in research production in infection diseases in terms of both quantity and quality [6], in respiratory research productivity where countries from Western Europe, Canada and Oceania had the best performance after adjustment for population and gross national income per capita [7], in cardiovascular research production where the results showed a promising trend of research productivity for developing world regions with the exception of Africa [8], and also look at the bibliometric profile of tropical medicine and international health [9]. In health informatics studies have included an up-to-date view of the telemedicine and telehealth literature analyzing the changes in content themes [10], assessing the impact of grants in the contribution to scientific knowledge of health information technologies on patient safety and quality of care outcomes [11], quantifying the number of publications on electronic health records and their changes over time [12], and studying the contribution of individual countries to leading journals in medical informatics [13]. Among occupational health, articles have helped to identify the most pertinent journals in the practice of occupational health and to develop search strategies that facilitate finding occupational health intervention studies [14–16]. There are also bibliometric analysis published in health management that investigate the attention and progress of strategic management in the literature [17], in health economics, studies have reported the growth of health economics literature and the change in topics and geographical focus of health economics [18–20]. Bibliometric studies in health service research have looked for trends, gaps and characteristics when comparing among different regions [21, 22], in the same line other studies have assessed the scientific production in health policy [23, 24], in primary health [25, 26], in epidemiology [27, 28], in environmental health [29–31], in public health and preventive medicine [32, 33], in preventive medicine, occupational and environmental medicine, epidemiology, and public health [34], and also public in health research in specific countries or regions [35–42]. This literature has become relevant today perhaps due to the diverse disciplines that are engaged in health research and its importance in order to monitor and disseminate the scientific achievements from the research work.
In this current study we aim to expand the scope of analysis of health research even more, identifying and quantifying the scholarly publications in the field and subfield approaches of public health, environmental and occupational health, health management and economics, health promotion and health behavior, epidemiology, health policy and services, medicine, health informatics, engineering and technology and primary care. Our main goal is to produce an overview of the leading journals in health research literature in the world for a time frame of 25 years from 1990 to 2014. There are many aspects that can indicate the value of a journal; in this study we use the number of citations and their impact factor to reflect the quality of the review process and its popularity in the scientific community. Findings from this research may assist researchers to identify top performance journals in a subject area, learn more about the subfields of health research, and identify emerging areas of research to locate areas of potential study.
Methods
There are different approaches for classifying the bibliographic material. Bibliometrics is one of the most common approaches [43, 44]. In order to represent the results, the analysis uses a wide range of indicators that measure the quality of the publications. Currently, there is no general agreement on the optimal method for measuring research because depending on the perspective considered an indicator may be better than another one. Therefore, the current literature deals with many indicators that have appeared during the last years [45–47]. In this study, the aim is to provide a general picture in order to get a complete overview that can adapt to the interests and perspectives of each specific reader. Thus, several indicators are considered including the total number of publications and citations, the citations per paper, the h-index [48] and the number of papers that a journal has among the most cited ones in a specific field. Note that the most cited papers are found in Web of Science (WoS) by ordering the results of a search from the most cited papers to the less cited [49].
The study uses the WoS database in order to search for the information. WoS is usually regarded as the most influential database for scientific research because it includes those journals that are generally recognized with the highest quality. It was originally created by Eugene Garfield with the name of Institute for Scientific Information (ISI). Later, Thomson & Reuters bought the ISI, renaming it ISI Web of Knowledge and later WoS. Note that other databases are available and could also be used in the analysis including Scopus and Google Scholar. Scientific research is divided in 251 categories in WoS. Four of them involve health research: Public, Environmental & Occupational Health, Health Policy & Services, Health Care Sciences & Services, and Primary Health Care. Note that the first one appears both in the Science Citation Index and in the Social Science Citation Index. These four categories encompass 363 journals. Since these four categories are very broad, the study divides health research in nine categories in order to get a deeper picture of the leading journals in each subfield. However, it is worth noting that sometimes it was not clear where to classify a journal because its scope may include two or three subfields. In any case, the analysis considers a Global Ranking (GR) where all the journals are ranked together. This allows comparison between subfields when needed. The nine categories are:
Public Health
Environmental and Occupational Health
Health Management and Economics
Health Promotion and Health Behavior
Epidemiology
Health Policy and Services
Medicine
Health Informatics, Engineering and Technology
Primary Care
Although the work considers many indicators, the ranking is carried out according to the total number of citations. The main reason for this is that the citations measure the influence that a journal has in absolute terms. Other alternatives could be considered including the citations per paper and the h-index. The main limitation of this indicator is that it does not take into account the number of papers that have generated the number of cites. However, the rest of indicators included in the tables allow the reader to get a comprehensive overview of each journal although the ranking is focused on the number of citations.
The analysis focuses on the last 25 years (1990–2014). The main reason is because this time period is representative of the latest developments of the field. In order to take into account the influence from a classical perspective, the study includes an indicator that shows the number of articles that a journal has among the 200 most cited articles published before 200. This allows the reader to see those journals that were very influential before and see if they are still leading the field or not. Note that the search process carried out in WoS has been developed between March and August 2015. The types of documents considered are: articles, reviews, notes and letters.
Results
This section presents the main bibliometric results found in WoS for 363 health research journals from 1990 to 2014. The results are ordered by category and each table contains the 20 or 10 most cited journals of each category (see the Additional file 1 for the full list of journals).
Public health
Public health refers to the activities to prevent diseases, promote health, and prolong life for the whole population [50]. Therefore, the main objective of public health is assuring conditions for the people in order to be healthy. It is at the core of health research and consequently there are many journals devoted to increase knowledge and raise awareness on this topic. Table 1 shows the most influential journals among this category.

The journal that has received more citations and the higher h-index in this field is the American Journal of Public Health with 302,196 citations and an h-index of 198; followed by Social Science & Medicine with 281,663 citations and an h-index of 163. These two journals dominate the number of citations in the field with more than 50 % of all the cites. Despite these elevated numbers, the highest average citation rate per paper, impact factor, and 5-year impact factor is for the Annual Review of Public Health.
Analyzing the T50 and T200 ranking results, Social Science & Medicine is in the top positions with 17 papers or 34 % of the papers in the T50 ranking of the category, followed by the American Journal of Public Health with 30 % of the papers in the T50. The same journals have 9 and 14 papers respectively in the T200 ranking. Note that all the journals of the category have an h-index bigger than 20, reflecting its influence and productivity.
Environmental and occupational health
Environmental health studies the impact of our surroundings in health, while occupational health studies all aspects of health and safety in the workplace. This category includes journals regarding the understanding of the impact and control of environmental and occupational hazards on human health and society. Table 2 presents the results for this category.

Note that the columns of the T200 and the T200* do not sum up to 200 because some of the most cited papers were published in journals that currently are not indexed in WoS for several reasons
Abbreviations: NJ Number of journals
Epidemiology is the most influential category over the last 25 years with the highest number of citations, citations per paper, h-index and the largest number of articles among the 200 most cited before and after 1990. Public Health also obtains very remarkable results being the category with the largest number of articles. However, the category with the highest number of journals is Health Promotion and Health Behavior.
Discussion and conclusions
This study showed some remarkable viewpoints about health journals currently indexed in WoS database between 1990 and 2014. This analysis shows the results obtained by health journals under a wide range of bibliometric indicators. This is very useful to see the general results from a broader perspective than the Journal Citation Reports of WoS. Particularly, this is very useful for PhD students and newcomers in the field in order to get a general orientation of the leading journals in health research.
The results provide a general picture of the current position of the leading journals in this field for the nine categories analyzed, which can be rank in terms of total papers as follows: (1) Public Health, (2) Health Promotion and Health Behavior, (3) Medicine, (4) Environmental and Occupational Health, (5) Epidemiology, (6) Health Policy and Services, (7) Health Management and Economics, (8) Health Informatics, Engineering and Technology, and (9) Primary Care. The results indicate that Epidemiology is the most influential category although Public Health is the largest one. Focusing on journals, the American Journal of Epidemiology, Environmental Health Perspectives, American Journal of Public Health, and Social Science & Medicine, have the highest number of citations which shows the largest influence in absolute terms. However, some other journals achieve better results when looking to other indicators. For example, according to the citations per paper ratio, the leading journals are Epidemiologic Reviews, Annual Review of Public Health, and Journal of Health and Social Behavior. This indicates that the journals considered in the study have different profiles with a wide variety of objectives. Almost all the leading journals are published in English although some journals may also publish in some other popular European languages including German, Spanish, French and Italian. Note that many journals have entered the WoS database during the last years although the most popular ones have been in the database for a long time.
In conclusion, by bibliometric methodology, the findings and suggestions of this study can help scientific researchers understand the performance and trends of health research globally. With the help of these findings researchers can make informed decisions of their research directions, in terms of identifying top journals of the discipline, and choose exchange platforms for their research. This study also helps to learn more about the subfields of health research, and identify emerging areas of research today such as public health, health promotion and health behavior and epidemiology, and also how most areas of health research have started to decline in number of citations from 2006.
From a general perspective, health research is a very broad area that includes a wide range of topics. This article classifies the material according to some of the most significant topics. However, it is worth noting that more specific topics could also be considered because each journal considers specific topics that do not depend on the topics followed by other journals. Moreover, the study assigns each journal to one category but sometimes the journal could also be considered in another category. For solving this issue, the last column of each table (GR) considers the global ranking that each journal obtains when merging all the journals in the same list and ordering according to the number of citations. This allows comparison between journals from different categories. But note that each category or group of journals may have a different profile with a different volume of publications and citations. Therefore, it is not easy to compare journals with different topics and categories. Finally, recall that WoS has several limitations when classifying bibliographic material that should also be considered in this article [49]. Additionally, many other issues may affect research in this field including open access and electronic journals. Note that only those included in WoS are considered in the analysis.
