Abstract  

The purpose of this work was to analyse the non-Science Citation Index subject visibility of the Latin American production in the health field. The methodology used considered manual and automated retrieval of the Latin American journals, as covered by different conventional secondary sources. The IMLA/LILACS (Index Medicus Latinoamericano/Latin American Literature in the Health Sciences) database was used to obtain a master list of the sustained journals for the period 1979–1990. The selected journals were classified by subject content, following the scheme of the U.S. National Library of Medicine. A total of 221 journals were selected and a database was developed. The results corroborated the leadership of Brazil in the field. It was also found that the subject content had a strong trend toward the clinical, medicine field. The subject Medicine was head in the list, with seventy four journals. Several difficulties and barriers to the use of the IMLA/LILACS database were detected. The implications of the overall analysis of this study as affecting researchers, policy makers and data-base producers are stressed by the author.

Abstract  

The study seeks to identify the influence of local and regional publications in the production of public health research papers in the Latin American region. A citation analysis of the papers published in the following three leading journals in the field of public health was conducted: Revista Médica de Chile (Chile) (RMCh); Archivos Latinoamericanos de Nutrición (Venezuela) (ALAN); and Salud Pública de México (México) (SPM). Papers were analyzed for the period 2003–2007. SciELO (Scientific Electronic Library Online) and the printed version of the journals were used in the analysis. Overall, 1,273 papers from 122 journal issues were analyzed. References accounted for a total of 38,459. Over 90% of the production was published through the collaboration of two or more authors. Author affiliation corresponded in most cases to the country of origin of the journal. References to Portuguese papers accounted for nearly 5% in ALAN and less than 1% each in SPM and RMCh. Citations among the three journals were not significant. Only ALAN cited RMCh and SPM over 3% each, of total citations. SPM and RMCh cited each other less than 1% of total citations. With the exception of ALAN, most public health papers published in RMCh and SPM derived from the national collaboration of researchers in the field. A small amount of public health knowledge communication was being transferred from Brazil to the region through RMCh and SPM. A vertical and individual (per journal/country) model of knowledge communication in public health was identified.

Abstract  

This work reports on the medical subject headings that build-up the medical education field in Latin America, through the content and citation analysis ofEducation Medica y Salud (EMS). An attempt was made to establish the articulations between the citing and cited countries in the region. It was generally found that EMS was built-up by subjects of Medical Education, Health Manpower, Water Supply, and Health Policy. Although strongly citing/cited/indexed countries, Brazil, Mexico, and Colombia have not established significant information flows among them. Further research lines are proposed.

Abstract  

This work reports the first results of a research in progress on the production, dissemination and impact of the literature on primary health care (PHC), as produced in Mexico during the period 1980–1992. The methodology used involved computerized searches in the MEDLINE, LILACS, and PERIODICA databases to identify the existing Mexican literature in the field. Results indicated a limited dissemination of the Mexican production through conventional databases. A total of 117 references were found in the field. Most of these references (72.65%) corresponded to journal articles. Over 55% of the documents were published by more than one author. Further research in the field as well as the implications of these results to PHC in Mexico are discussed by the author.

Abstract  

This work reports on the subject content analysis performed to 1323 records retrieved from international databases, related to the Mexican production on environmental health. The U.S. National Library of Medicine's Medical Subject Headings (MeSH) and BIREME's Health Sciences Descriptors (DeCS) were used as guiding tools to select the subject content of records. Overall, 97 descriptors were identified; 65 corresponded to MeSH terms and 32 were, generated by the authors. Results indicated that most of the production was related to environmental pollution studies focused on water and air pollution, and environmental monitoring. Through the development of hierarchical models, patterns of subjects covered and uncovered could be easily identified. Further lines of action and research are proposed by the authors.

Abstract  

This work reports on the preliminary results of a bibliometric analysis of AIDS literature, as produced in or about Latin America and the Caribbean for the period 1980–1996. Two international and two regional secondary sources were used in order to obtain comparative analyses regarding for example, comprehensiveness of AIDS literature coverage and local/main frame visibility. Less than 1000 records were retrieved from each of the databases searched. Leading countries in AIDSLINE were Haiti, Brasil, Mexico and Puerto Rico. The distribution by year of publication showed a decrease in Haiti records, from 54 in 1983, to 4 in 1995. The rest of the countries either increased or maintained an average production throughout the years. Regional secondary information sources were less current and comprehensive in the field. Further lines of research are described by the authors.

Abstract  

The purpose of this paper is to present the preliminary results of a research in progress regarding the subject content analysis of AIDS literature, as produced in or about the Latin American and Caribbean (LAC) region. An AIDSLINE/OVID literature search was conducted to obtain only the Medical Subject Headings (MeSH)-geographic-terms related to the LAC region. The period of study was from 1982 to June, 1998. Indicators regarding the distribution of records throughout the years of study, as well as the subject, check tags, and subject/subheadings distribution patterns were analysed. This was done through the application of a modular bibliometric information system, as well as the applications of Biblio-Link for Windows, Version 1.2 1994–1997, Research Information Systems; Pro-Cite for Windows, Version 4.0.1 1995–1998, Research Information Systems; and Microsoft EXCEL 97, of 1985–1998, Microsoft Corporation. A total of 4124 records were obtained and analysed. In descending order, Brazil, Mexico, Haiti, Argentina and Puerto Rico, generated the highest number of citations. Highly ranked MeSH subject headings wereRisk Factors; Acquired Immunodeficiency Syndrome; Sex Behavior, Support, Non U.S. Govt.; HIV Infections; andDeveloping Countries. Results demonstrate that major research concerns centred on the epidemiological aspects and transmission of AIDS; and more recently, on the prevention and control of the disease. A swith of the studies from male to female, and from middle age to adolescence was also observed. The authors provide further lines of research.
