Brief Background
|
The Brazilian Journal of Epidemiology (Revista Brasileira de Epidemiologia – EPIDEMIO) is a continuous publication edited by the Brazilian Association of Collective Health (Associação Brasileira de Saúde Coletiva – Abrasco). Its mission is to publish original articles, reviews, and theoretical or methodological essays that contribute to the advancement of knowledge and the development of epidemiology and related fields. The journal has been published uninterruptedly since 1998, and all articles are currently available in English. Its official abbreviation is Rev. bras. epidemiol., which should be used in bibliographies, footnotes, references, and bibliographic legends. |
Open Access
|
EPIDEMIO follows the Open Access model, allowing unrestricted online access (including the absence of financial barriers) to all published scientific texts. Open access is defined as the condition in which the copyright holder of a scholarly work grants usage rights to third parties through an open license (Creative Commons Attribution, CC-BY), allowing immediate free access to the work and authorizing any user to read, download, copy, distribute, print, search, or link to the full texts of articles, crawl them for indexing, transmit them as data to software, or use them for any other lawful purpose. |
Open Science Compliance
|
The journal’s editorial policy adopts research communication in accordance with the modus operandi of open science. EPIDEMIO follows the Gold Open Access model. All published articles are made freely available for anyone to read, download, and share, without subscription or paywall barriers. The journal is also aligned with open science practices. Submissions of manuscripts deposited in reliable preprint servers are accepted, regardless of whether the deposition occurred before or during the journal’s peer review process. Authors are encouraged to make data and analytical workflows publicly available whenever possible. Upon submission of a manuscript to EPIDEMIO, the corresponding author must complete and attach the Open Science compliance form. |
Ethics in Publication
|
EPIDEMIO adheres to the ethical and transparency guidelines for publication set forth in the document Principles of Transparency and Best Practice in Scholarly Publishing, issued by the Committee on Publication Ethics (COPE), the Directory of Open Access Journals (DOAJ), the Open Access Scholarly Publishers Association (OASPA), and the World Association of Medical Editors (WAME). |
Focus and Scope
|
EPIDEMIO publishes original scientific contributions in the field of epidemiology and related areas of public health. Its objective is to disseminate scientific knowledge that contributes to the understanding of the determinants of the health-disease process, their distribution, and the control of health conditions affecting populations, as well as to promote the improvement of surveillance, prevention, and health promotion practices. Priority is given to manuscripts that demonstrate originality, innovation, scientific rigor, relevance to public health policies, and impact on the development of epidemiology in Brazil and in other international contexts. The journal’s target audience includes researchers, faculty members, graduate students, and professionals and managers involved in the production, analysis, and use of epidemiological information to strengthen public health actions. |
Digital Preservation
|
EPIDEMIO follows the standards established by the SciELO Program Digital Preservation Policy, guided by the principles of authenticity, integrity, provenance, reliability, and usability. The preservation processes adopted are transparent and auditable, and all journal volumes are digitally preserved within the SciELO collection. |

Websites and Social Media
Preprints
|
EPIDEMIO accepts preprints as a means of rapid and broad dissemination of research findings prior to formal publication. Authors may share their preprints in recognized repositories either before or during the journal’s peer review process. The corresponding author must report the name of the server and the Digital Object Identifier (DOI) assigned to the work on the title page at the time of manuscript submission or, subsequently, via email <epidemio_submissao@abrasco.org.br>. Preprints will not be considered prior publication and will not influence the editors’ decision regarding formal publication. EPIDEMIO does not require submission to specific preprint platforms but recommends SciELO Preprints and medRxiv. |
Peer Review Process
|
The peer review process is a critical stage in the editorial workflow; therefore, EPIDEMIO devotes particular care to it. At the same time, the journal recognizes that efficiency in the editorial process is essential for both authors and the scientific community. Accordingly, EPIDEMIO strives to provide evaluations that uphold ethical standards, the highest level of scientific rigor, and timeliness. The process comprises the following stages:
EPIDEMIO screens all accepted manuscripts using similarity detection systems to identify potential plagiarism and emphasizes to reviewers the importance of strict adherence to ethical standards for peer review as established by the Committee on Publication Ethics. The final published version of each article includes the name of the editor responsible for overseeing the peer review process. |
Open Data
|
Research data comprise content such as numbers, texts, codes, images, audio, and video, among others, that underpin the results presented in articles. Whenever possible, authors are encouraged to make these data publicly available, along with the analytical routines used in data processing and analysis. Authors should select repositories appropriate to the manuscript’s field of knowledge or multidisciplinary repositories, always adhering to reliable options. A list of possible repositories is available here. EPIDEMIO also highlights SciELO Data, a multidisciplinary repository for the deposit, preservation, and dissemination of research data. All original research and review manuscripts accepted for publication in EPIDEMIO must include a data availability statement regarding the data used or generated in the study, even if the data are not available for sharing. For other types of manuscripts, this statement is optional. The data availability statement must be included in the Methods section of the manuscript and may follow the examples provided in the “Guide for promoting openness, transparency, and reproducibility in research published by SciELO” Journals (topic 1) and the “Guide for research data curation for editorial teams” (item 2.2). Additionally, any dataset that is made publicly available must be cited in the text, and the corresponding reference included in the appropriate section, as illustrated in the example below: Batista JFC. Tuberculose em pessoas em situação de rua no Brasil, 2014–2022: tendência temporal dos indicadores epidemiológicos e fatores associados ao abandono de tratamento e óbito [dataset]. SciELO Data [Internet]. 2025 May 7 [cited 2025 Jun 22]. Available from: https://doi.org/10.48331/scielodata.8KFIGO |
Fees
|
The English-language version of articles is fully funded by EPIDEMIO. However, the editorial processing fee is the responsibility of the authors. The fee is reviewed periodically and, for manuscripts submitted as of June 3, 2026, is set at R$1,000 for brief communications and R$1,500 for all other article types. The fee is charged only after manuscript acceptance, and authors must await communication from the journal’s executive office with instructions for payment. Invoices and other supporting documents are provided by the journal for submission to educational and research institutions, funding agencies, and other entities. Requests for fee reductions may be submitted by authors with appropriate justification, particularly when all authors are affiliated with CAPES graduate programs rated at levels 3 or 4 in any region of Brazil, or when authors are exclusively affiliated with municipal and/or state health departments. EPIDEMIO will assess the eligibility for granting additional subsidies. |
Ethics and Misconduct, Correction and Retraction Policy
|
Research misconduct
Retraction policy
Editors will carefully evaluate each case of potential retraction, conducting a thorough investigation in accordance with the workflows established by COPE guidelines. If retraction is deemed necessary, the journal will publish it on numbered pages in the same section in which the original article appeared, including an explanatory note clearly describing the reason for the retraction.
Post-publication corrections policy Editors will assess each proposed correction carefully and determine whether it is necessary and whether it should be published. Administrative procedures and the workflow for evaluating post-publication corrections follow the recommendations established by COPE. |
Policy on Conflict of Interest
|
All authors must disclose the presence or absence of conflicts of interest related to the conduct of the study. Conflicts of interest may arise when any author or institution has relationships of any nature with organizations or individuals that could influence the study in question. Examples of conflicts of interest include employment relationships, provision of consulting services, funding or other financial support received, equity ownership in companies, patent holdings, and honoraria. Authors must declare, using the form available at the end of this page, whether a conflict of interest exists and, if so, its nature. |
Adoption of Similarity Software
|
EPIDEMIO uses Crossref Similarity Check (powered by iThenticate) to assess the originality of submitted manuscripts. All accepted articles undergo this screening, and the resulting reports are evaluated by the editorial board. If indications of excessive similarity or plagiarism are identified, the authors are notified, provided with the report generated by the analysis tool, and invited to submit an explanation. Depending on the nature and severity of the issue, the manuscript may be rejected or revised, with the final decision resting with the EPIDEMIO editorial board. |
Adoption of Software Using Artificial Intelligence Resources
|
The use of artificial intelligence (AI)-based technologies - including language models, image generation tools, analytical software, or other similar technologies - may be permitted within ethical and copyright boundaries, provided that such use is transparently disclosed in all manuscripts submitted to EPIDEMIO. AI tools must not be listed as authors or co-authors of the manuscript and should not be cited as primary references. Full responsibility for the accuracy, originality, and integrity of the text and analyses rests with the authors. |
Gender and Sex Issues
|
Editors, reviewers, and authors of EPIDEMIO must adhere to the Sex and Gender Equity in Research (SAGER) guidelines. The SAGER guidelines comprise a set of recommendations that guide the reporting of sex and gender information in study design, data analysis, and the reporting and interpretation of findings, as described in the English version (available here) and in the Portuguese version (available here). In addition, EPIDEMIO observes gender equity principles in the composition of its editorial board and reviewer pool. |
Ethics Committee
|
All manuscripts submitted to EPIDEMIO must comply with research ethics recommendations set forth in the Declaration of Helsinki and with the standards established by Brazilian National Health Council Resolutions No. 466/2012 and No. 510/2016. For studies conducted in Brazil, the Research Ethics Committee approving the investigation must be registered with the National Research Ethics Commission (Comissão Nacional de Ética em Pesquisa – CONEP). Studies conducted outside Brazil must have approval from a Research Ethics Committee with the legal authority to review and approve the conduct of the research. Approval by a Research Ethics Committee is waived for studies analyzing aggregated, non-identifiable data, such as those available in official public-domain databases.
All research involving human participants must ensure informed consent from participants or their legal representatives. Participants or their legal representatives must be clearly informed about the study objectives, methods, and potential risks and benefits. They must be provided with the researchers’ contact information and assured of their right to withdraw from the study at any time. The process for obtaining informed consent and its content must be reviewed and approved by a Research Ethics Committee, and such approval must be documented and submitted to EPIDEMIO at the time of manuscript submission. Clinical trial registration EPIDEMIO supports the policies of the World Health Organization (WHO) and the International Committee of Medical Journal Editors (ICMJE) regarding clinical trial registration, recognizing the importance of these initiatives for transparency and the international dissemination of open-access information. Accordingly, only clinical research articles that have received an identification number from a clinical trial registry validated according to WHO and ICMJE criteria will be considered for publication. The registration/approval number must be provided on the title page. |

The information and concepts presented in the articles, as well as the accuracy of the research content, are the sole responsibility of the author(s). |
Authors' Contribution
|
For the definition of authorship, EPIDEMIO follows the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly Work in Medical Journals established by the International Committee of Medical Journal Editors. Authors must adhere to the ICMJE guidelines, translated into Portuguese in the article by Duarte and Pansani (2015). The contributions of each author must be specified at the time of manuscript submission. EPIDEMIO adopts CRediT, which includes 14 possible roles describing authors’ contributions to the study. Further information is available on its official website. This information must be provided directly within the manuscript submission platform (ScholarOne) and on the Title Page. |
Manuscript Preparation
|
Authors are initially advised to verify that the manuscript aligns with the scope of EPIDEMIO. Once this relevance has been confirmed, the text should be structured to clearly demonstrate its scientific significance, presenting, in the Introduction, a well-founded and coherent rationale. The Methods section must be clear and sufficiently detailed to ensure understanding and reproducibility of all procedures adopted. The Results should be consistent with the Objectives and Methods, making precise and effective use of textual, tabular, and graphical elements. In the Discussion, an analytical and critical interpretation of the findings is expected, going beyond mere comparison with the existing literature to explore explanatory hypotheses, implications, and potential developments. Study limitations must be thoroughly examined in the Discussion, addressing how they may have influenced the results. Authors are encouraged to consult and adhere to established reporting guidelines when preparing their manuscripts. For clinical trials, CONSORT are recommended; for observational studies, STROBE; for systematic reviews, PRISMA; and for studies based on secondary data, RECORD. The EQUATOR (Enhancing the QUAlity and Transparency Of health Research) Network portal is recommended for access to additional reporting guidelines and guidance aimed at ensuring quality and transparency in health research. |
