Submissions of Files

Jornal de Pediatria is the official publication of the Sociedade Brasileira de Pediatria (SBP). It has been continuously published by the SBP since 1934. An online, full-text version of Jornal de Pediatria is available from in both Portuguese and English. Access to the website is free of charge. Jornal de Pediatria is indexed in the following databases: Index Medicus/MEDLINE (, SciELO (, LILACS (, EMBASE/Excerpta Medica (, Sociedad Iberoamericana de Información Científica (SIIC) Data Bases (, Medical Research Index ( and University Microfilms International.

Jornal de Pediatria publishes articles in the field of clinical investigation. Exceptionally, basic research articles are also accepted. Papers can be submitted in either Portuguese or English Articles are published in English and Portuguese. American spelling is used. Therefore, authors are advised to use the language with which they feel most comfortable and confident that they will communicate more clearly. If a certain paper has been originally written in Portuguese, the authors should not submit an English version, unless it is a professional quality translation. Important notice: The official language of publication of Jornal de Pediatria is English, and so is the language of its entire submission web site.


Guidelines for manuscript preparation

Peer review

All materials published by Jornal de Pediatria undergo peer review. Each manuscript is sent to the editors, who make sure that minimum standards and format requirements are met. The manuscript is then sent to two expert reviewers who are not members of the editorial staff. The reviewers are never from the same institution as the authors. Based on the comments of these two reviewers, the Editorial Board decides whether the manuscript should be published as is, rejected or returned to the authors for amendment. A manuscript may be returned to its authors several times for clarification and improvement and, at any time, it can be rejected. Each revised version is always analyzed by the Board, which makes the final decision.

Types of articles

Jornal de Pediatria accepts submissions of original articles, special articles, and letters to the editor.

Original articles include reports on controlled and randomized studies, screening and diagnostic studies, and other descriptive and intervention studies, as well as reports on basic research carried out with laboratory animals. Manuscripts in this category should not exceed 3,000 words, 30 references and four tables and figures.

Clinical trials should be registered in one of the Clinical Trial Registries recommended by the World Health Organization and the International Committee of Medical Journal Editors. In the absence of a Latin American registry, Jornal de Pediatria suggests the National Institutes of Health’s registry, available at The clinical trial identification number should appear at the end of the abstract.

Please access for further information on how to publish this type of article.

Special articles do not fall under any of the other categories. They are considered to have special relevance and will be reviewed following special criteria. Special articles are not limited in terms of length or number of references.

Letters to the editor usually express an opinion, discuss or criticize articles previously published in Jornal de Pediatria. Letters should not exceed 1,000 words and six references. Whenever possible, a response from the authors of the article to which the letter refers will be published along with the letter.

Editorials, comments and review articles are published under invitation. Authors of unsolicited editorials, comments, and review articles must submit an outline to the Editorial Board before submitting the manuscript.

Editorials and comments, which usually make reference to selected articles, are solicited from experts in the field. The Editorial Board may consider the publication of unsolicited comments.

Review articles are systematic, critical assessments of the literature concerning topics of clinical relevance, with emphasis on aspects such as cause and prevention of diseases, diagnosis, treatment, and prognosis. Usually, professionals of recognized expertise are invited to write review articles. Meta-analyses are included in this category. Jornal de Pediatria will also consider unsolicited review articles. For that, authors must submit an outline to the Editorial Board before submitting the manuscript. Review articles should not exceed 6,000 words, not including references and tables. A minimum of 30 up-to-date references should be cited.

General guidelines

The file - including tables, figures, and references - should be in accordance with the "Uniform Requirements for Manuscripts Submitted to Biomedical Journals," published by the International Committee of Medical Journal Editors ( Each section should start on a new page in the following order: title page, abstract, main text, acknowledgements, references, tables (print or insert each table, with title and footnotes, on a separate page), figures (print or insert each graph, with title and footnotes, on a separate page), and figure legends.

The main recommendations for each section are as follows:

Title page. The title page should contain all the following information:

  1. concise and informative title. Avoid unnecessary terms and abbreviations; also avoid reference to the site and/or city where the work was carried out;
  2. short title of not more than 50 characters including spaces to appear on the headers;
  3. authors’ names (first and last names and middle initials);
  4. e-mail address of all authors;
  5. if available, URL to electronic curriculum vitae; Brazilian authors are advised to inform the URL to "Currículo Lattes";
  6. the specific contribution of each author to the study;
  7. statement of conflicts of interest (write "nothing to declare" or clearly disclose any financial or other interests which could cause embarrassment if revealed after the publication of the article);
  8. institution or service with which the work is associated for indexing in Index Medicus/MEDLINE;
  9. name, address, telephone number, fax number, and e-mail of corresponding author;
  10. name, address, telephone number, fax number, and e-mail of author in charge of pre-publication contacts;
  11. funding sources, or name of institutions or companies providing equipment and materials, if applicable;
  12. word count of the main text not including abstract, acknowledgements, references, tables and legends to figures;
  13. abstract word count;
  14. number of tables and figures.


The abstract should have no more than 250 words or 1,400 characters, and abbreviations should be avoided. Do not include words that could identify the institution or city where the study was performed, to facilitate blind review. All information in the abstract must accurately reflect the content of the article. The abstract should be structured as described below:

Abstract for original articles

Objective: State why the study was initiated and any initial hypotheses. Precisely define the main purpose of the study; only the most relevant secondary objectives should be listed.

Method: Describe the study design (if appropriate, state whether the study is randomized, blinded, prospective, etc.), setting (if appropriate, describe the level of care, i.e., primary, secondary or tertiary, private clinic or public institution, etc.), patients or participants (selection criteria, number of cases at the beginning and at the end of the study, etc.), interventions (include essential information, such as methods and duration of the study), and criteria used to measure the outcomes.

Results: Describe the most important findings, confidence intervals, and statistical significance of the findings.

Conclusions: Only describe conclusions that reflect the purpose of the study and that are supported by your findings. Discuss possible applications of the findings, with equal emphasis on positive and negative findings that have similar scientific merit.

Abstract for review articles

Objective: Explain why the review was performed, stating whether it focuses on a special factor, such as disease etiology, prevention, diagnosis, treatment or prognosis.

Sources: Describe all sources of information, defining databases and years researched. Briefly state the criteria used to select articles for review and to assess the quality of information.

Summary of the findings: State the main quantitative or qualitative findings.

Conclusions: State your conclusions and their clinical application, keeping generalizations within the scope of the subject under review.

Below the abstract, include three to six keywords that will be useful for indexing purposes. Please use Medical Subject Headings (MeSH), available at Whenever adequate descriptors are not available you may use new terms.

Abbreviations should be avoided and are not accepted in titles or in the abstract. If used, abbreviations should be defined the first time they appear in the text.


The main text in original articles should contain the following sections, indicated by a subtitle:

  1. Introduction: Make it brief, including only references that are strictly relevant to underscore the importance of the topic and to justify the study. At the end of the introduction, research objectives must be clearly stated.
  2. Methods: This section should describe the study population, the sample being analyzed, and the selection criteria; it should also clearly define the variables under study, and describe in detail the statistical methods employed (including appropriate references about statistical methods and software). Procedures, products, and equipment should be described in sufficient detail so as to allow reproduction of the study. A statement concerning approval by the research ethics committee (or equivalent) of the institution in which the work was carried out must be included.
  3. Results: Study results should be presented in a clear, objective manner, following a logical sequence. Information contained in tables or figures should not be repeated in the text. Use figures rather than tables to present extensive data.
  4. Discussion: Results should be interpreted and compared with previously published data, emphasizing new and important aspects of the present study. Discuss the implications of the findings and the limitations of the study, as well as the need for additional research. Conclusions should be presented at the end of the Discussion section, taking into consideration the purpose of the work. Relate the conclusions to the initial study objectives, avoiding statements that are not supported by the findings and giving similar emphasis to positive and negative findings that have similar scientific relevance. If relevant, include recommendations for further research.

The sections in review articles may vary depending on the topic. We suggest that authors include a brief introduction, in which they explain (from the perspective of the medical literature) the importance of the review for the practice of pediatrics. It is not necessary to describe how data were selected and collected. The conclusions section should correlate the main ideas in the review to possible clinical applications, keeping generalizations within the scope of the subject under review.


Acknowledgements should be brief and objective; only individuals or institutions that contributed significantly to the study, but are not qualified for authorship, should be mentioned. Individuals cited in this section must agree in writing to the inclusion of their names, since readers may infer their endorsement of the conclusions of the study.


References should follow the Vancouver style, also known as the Uniform Requirements style, which is based largely on an American National Standards Institute style adapted by the U.S. National Library of Medicine (NLM) for its databases. Authors should consult Citing Medicine, The NLM Style Guide for Authors, Editors, and Publishers ( for information on the recommended formats for a variety of reference types. Authors may also consult sample references (, a list of examples extracted from or based on Citing Medicine for easy general use; these sample references are maintained by NLM.

References must be numbered consecutively in the order in which they appear in the text, identified by superscript numbers. Do not use automatic numbering, footnotes or end notes for references.

Unpublished articles that have been accepted for publication may be included as references if the name of the journal is included followed by "in press."

Unpublished observations and personal communications should not be cited as references; if this information is essential for the understanding of the article, it may be cited within the text, followed by the observations in parentheses "unpublished observation" or "personal communication." Titles of journals should be abbreviated according to the Index Medicus; for a comprehensive list of journal title abbreviations, see the List of Serials Indexed for Online Users, available at For more detailed information, refer to the Uniform Requirements for Manuscripts Submitted to Biomedical Journals, available at Below we present some examples of the model adopted by Jornal de Pediatria:

Each table should be typed on a separate sheet of paper, numbered consecutively in the order in which it appears in the text. Tables should have a brief but comprehensive title. All explanatory notes should be presented as footnotes indicated by superscript lowercase letters assigned in alphabetical order.
Do not underline or separate lines with borders. Do not use the space bar to create columns. Do not leave a space before or after the symbol ±.

Figures (photographs, drawings, graphs, etc.)

All figures should be numbered consecutively in the order in which they have been first cited in the text. All explanatory notes should be included in the figure legend. Reproduction of previously published figures should be indicated in the legend, and must be accompanied on submission by a permission letter from the copyright holder. Photographs should not allow identification of patients; please note that masking the eye region may not be sufficient to protect the patient’s anonymity. If any photographs allow a patient to be identified, a written permission to use the photograph must be provided. Photomicrographs should present internal scales and arrows that contrast with the background.

Jornal de Pediatria publishes color illustrations online. However, all figures will be converted into black & white format for publication in print. If the authors consider that color is essential, they should contact the editors. Computer-generated images, such as graphs, should be attached as .jpg, .gif, or .tif files, with a resolution of at least 300 dpi, to enable good-quality reproduction. This resolution will be adjusted to 72 dpi for online publication. Do not submit three-dimensional graphs. If the resolution of scanned drawings, photographs, or illustrations is not adequate for printing, submit your manuscript via regular mail with two copies of the original illustrations (professionally drawn or printed with a resolution of 300 dpi or higher). In this case, affix a label to the back of the figure, indicating figure number, first author’s name, and top of the figure (with an arrow).

Figure legends

Legends should be included on a separate page, identified by figure number.
