Author Guidelines

Revised 12 February 2013


Submitted manuscripts should be arranged according to the rules stated in 'Uniform requirements for manuscripts submitted to biomedical journals' Ann Intern Med 1997;126:36-47, or JAMA 1997;277:927-34. The full document is available at

Ithenticate Acta Paediatrica employs a plagiarism detection system. By submitting your manuscript to this journal you accept that your manuscript may be screened for plagiarism against previously published works.

When submitting a paper, the author should make a full statement to the editor about all submissions and previous reports that might be regarded as redundant or duplicate publication of the same or very similar work. Publication of abstracts is not considered to be duplicate publication. Submit approval of the paper for publication, signed by all authors, to the Editorial Office, and state clearly in the paper that the study has been approved by an institutional ethics committee. An author must have made significant contributions to the design, execution analysis and writing of the study, and he or she must share responsibility for what is published. We ask authors to specify their individual contribution, if appropriate, we publish this information (Author statements). Example:
Dr A had primary responsiblity for protocol development, patient screening, enrollment, outcome assessment, preliminary data analysis and writing the manuscript.
Drs B and C participated in the development of the protocol and analytical framework for the study and contributed to the writing of the manuscript.
Dr D contributed in the same ways as B and C and was responsible for patient screening.
Dr E supervised the design and execution of the study, performed the final data analyses and contributed to the writing of the manuscript.

Be as concise as possible. Regular Articles may not exceed four published pages (including illustrations, tables and references). Exceeding this limit will incur a page charge for each exceeding page. Short Communications may not exceed two published pages. Clinical Observations will no longer be published.

Acta Paediatrica does not publish case reports. Authors of case reports are encouraged to submit to the journal Clinical Case Reports (, which aims to directly improve health outcomes by identifying and disseminating examples of best clinical practice. Clinical Case Reports is an open access journal, and article publication fees apply.

From 2011, some Regular Articles, Short Communications and Letters published in the Readers' Forum will be considered with the understanding that, if accepted, they will only be published online (Online-Only). All articles published Online-Only are included in both online and printed table of contents, are fully citable and indexed in Pubmed.

Reports on randomised trials must conform to Consort guidelines and should be submitted with their protocols.

Conflict of interest and funding
Authors are responsible for recognising and disclosing financial and other conflicts of interest that might bias their work. They should acknowledge in the manuscript all financial support for the work and other financial or personal connections to the work. If reported research has been supported by pharmaceutical or other industries, this should be stated.

Statistic validity
If statistical data are provided the authors may be requested to submit an official statement issued by a certified statistician (with a proper affiliation) regarding the validity of the methods used.

Publication Ethics
Acta Paediatrica is a member of the Committee on Publication Ethics (COPE).

Ethics and consent
When reporting experiments on human subjects, indicate whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation and with the Helsinki Declaration of 1975, as revised in 1983. Do not use patients' names, initials, or hospital numbers, especially in illustrative material. Papers including animal experiments or clinical trials must have been approved by the institutional ethics committee.

Identifying information should not be published in written descriptions, photographs, and pedigrees unless the information is essential for scientific purposes and the patient (or parent or guardian) has given written informed consent for publication (A Patient Consent Certificate should be completed and sent to the journal). Informed consent for this purpose requires that the patient be shown the manuscript to be published.

Prior to acceptance there is no requirement to inform an Editorial Office that you intend to publish your paper OnlineOpen if you do not wish to. All OnlineOpen articles are treated in the same way as any other article. They go through the journal's standard peer-review process and will be accepted or rejected based on their own merit.

Accepted Articles
Acta Paediatrica now offers Accepted Articles for all articles within a short time of acceptance.

Further to acceptance in Acta Paediatrica, the manuscripts of articles (excluding Quest for Diagnosis) are immediately made publicly available online. 'Accepted Articles' have been peer-reviewed and accepted for formal publication, but have not been subject to copyediting, composition or proof correction. The service has been designed to ensure the earliest possible circulation of research papers after acceptance. Accepted Articles appear in PDF format only and are given a Digital Object Identifier (DOI), which allows them to be cited and tracked. The DOI remains unique to a given article in perpetuity and can continue to be used to cite and access the article further to Early View publication (see below). More information about DOIs can be found online here.

Neither the Acta Paediatrica Foundation nor Wiley-Blackwell can be held responsible for errors or consequences arising from the use of information contained in Accepted Articles; nor do the views and opinions expressed necessarily reflect those of the Acta Paediatrica Foundation or Wiley-Blackwell.


Electronic Manuscripts
All submissions should be made online at Acta Paediatrica's Manuscript Central site to facilitate rapid accessibility of your work to the readers. New users should first create an account. Once a user is logged onto the site submissions should be made via the Author Centre. The submitting author will be required to suggest the names/email addresses of two reviewers and add the names, affiliations and email addresses of the co-authors. The accompanying letter should be entered in a separate field. The manuscript text, tables and figures should preferably be uploaded as separate files.

Manuscript Layout
Please use these simple guidelines when preparing your electronic manuscript.

(i) Key elements consistently throughout. (ii) Do not break words at the ends of lines. Use a hyphen only to hyphenate compound words. (iii) Use one space only at the ends of sentences. (iv) Do not use underlining; use the italics feature instead. (v) Leave the right-hand margin unjustified. (vi) Use a double hyphen to indicate a dash. (vii) Do not use the lower case 'ell' for 1 (one) or the upper case O for 0 (zero). (viii) When indenting paragraphs or separating columns in tables, use the TAB key, not the spacebar.

Double-space the entire manuscript. Prepare the manuscript with each of the following parts starting on a new page: (1) The title, with authors' names and affiliations (as a rule the number of authors should be limited to six. The names of others who contributed to the article in varying degree should be mentioned under the heading 'Acknowledgements'), the address of the corresponding author and a short running title; (2) the abstract ending with one or two sentences of conclusion, summarizing the message of the article including keywords; (3) the text; (4) the references; (5) tables; (6) figure legends.

Manuscripts must be in English. Authors from non-English speaking countries are requested to have their text thoroughly checked by a competent person whose native language is English. Manuscripts may be rejected on the grounds of poor English. Revision of the language is the responsibility of the author. For English-language editing services see

Incorporate notes/footnotes in the text, within parentheses, rather than in their usual place at the foot of the page.

Do not use abbreviations in the title or Abstract, and in the text use only standard abbreviations, i.e. those listed in the latest editions of any recognized medical dictionary (e.g. Dorland's, Butterworth's). The full term for which an abbreviation stands should precede its first use in the text, unless it is a standard unit of measurement. Use the SI system of notation. Redefine abbreviations used in the figure legends.

In manuscripts that contain photographs of patients, we require a certificate by the author that consent to publish such a photograph has been given by the patient, a child's parent or a caretaker.

All figures should be cited in the text in numerical order.  Figure legends must be typed on a separate page at the end of the manuscript.  When submitting artwork electronically, please read the information on the Wiley-Blackwell website at Vector graphics (e.g. line artwork) should be saved in Encapsulated Postscript Format (EPS), and bitmap files (e.g. photographs) in Tagged Image File Format (TIFF). Line art must be scanned at a minimum of 800 dpi, photographs at a minimum of 300 dpi.

Colour Figures
Authors are required to pay for any colour illustrations.  When your manuscript is accepted for publication, please submit the required Colour Work Agreement form. This form can be downloaded as a PDF file here: Colour Work Agreement. Color Work Agreement forms must be submitted as original, signed, hard copies in order to be processed. If your paper has colour images please post the original Colour Work Agreement form to:

Early View
Acta Paediatrica is covered by the Early View service. Early View articles are complete full-text articles published online in advance of their publication in a monthly issue. Articles are therefore available as soon as they are ready, rather than having to wait for the next scheduled issue. Early View articles are complete and final. They have been fully reviewed, revised and edited for publication, and authors' final corrections have been incorporated. Because they are in final form, no changes can be made after online publication. The nature of Early View articles mean that they do not yet have volume, issue or page numbers, so Early View articles cannot be cited in the traditional way.  They are therefore given a Digital Object Identifier (DOI), which allows the article to be cited and tracked before it is allocated to an issue. After issue publication, the DOI remains valid and can continued to be used to cite and access the article. More information about DOIs can be found at

Author Services
Online production tracking is available for your article through Wiley-Blackwell’s Author Services. Author Services enables authors to track their article - once it has been accepted - through the production process to publication online and in print. Authors can check the status of their articles online and choose to receive automated e-mails at key stages of production so they don’t need to contact the production editor to check on progress. Visit for more details on online production tracking and for a wealth of resources including FAQs and tips on article preparation, submission and more.

Free access to the final PDF offprint of your article will be available via author services only. Please therefore sign up for author services if you would like to access your article PDF offprint and enjoy the many benefits the service offers.
