Author Guidelines


Author Guidelines

Paediatric and Perinatal Epidemiology welcomes discussion documents, review articles, book reviews and correspondence as well as original research reports. The last of these should deal with original research not previously published or being considered for publication elsewhere. Topics of interest include the application of epidemiologic methods to studies of pregnancy complications, birth outcomes, fertility, genetic susceptibilities, and the influence of the fetal and early environment on child or adult health and development. We also encourage submissions on the development and applications of new and innovative methods to studies in paediatric and perinatal epidemiology.

All authors are expected to meet the criteria for authorship which they confirm by their signature on the letter of submission.

Case Reports
The journal does not accept case reports for publication. Authors of case reports are encouraged to submit to the Wiley Open Access journal, Clinical Case Reports www.clinicalcasesjournal.com which aims to directly improve health outcomes by identifying and disseminating examples of best clinical practice.

Manuscript Submission
Paediatric and Perinatal Epidemiology requires all manuscript to be submitted electronically at: (http://mc.manuscriptcentral.com/PPE). Log-in or click the “Create Account” option if you are a first-time user of ScholarOne Manuscripts. Full instructions and support for authors (and reviewers) are available on the site. Support can be contacted by e-mail at support@scholarone.com or at http://authorservices.wiley.com/bauthor/journal.asp. If you are having trouble submitting online, the Editor-in-Chief (cva2111@columbia.edu) may be able to assist.

Manuscript Structure
Manuscripts in English should be typed with double spacing on one side of the paper only. Pages should be numbered consecutively. Main subdivisions of the manuscript should be entitled Abstract, Methods, Results and Comments.

The Title Page of the manuscript should contain:
• The title of the paper
• List of authors (excluding qualifications), each followed by a superscript letter to link with an affiliation.
• The affiliations of the authors preceded by superscript letters denoting which author is at each institution.
• Address for correspondence (full mailing address, telephone and fax numbers and e-mail address).

The Abstract should always appear at the beginning of the manuscript, entitled Abstract and structured with the following sub-headings: Background, Methods, Results, Conclusions (250 words)

Text and references should be printed in double spacing, with indented paragraphs. Tables should be typed with double spacing, each on a separate sheet, numbered consecutively with Arabic numerals, containing only horizontal lines, and with a concise legend. Place explanatory matter in footnotes which should be indicated alphabetically in superscript. Tables should be created such that it is easy to determine what is being shown.

P-values: For results of regression analyses, give the P-value of the whole variable, not of each individual item. In general, actual P-values should be quoted, particularly for those of marginal significance. Where, in addition, levels of statistical significance are indicated in a table, use the following symbols: *P0.05; **P0.01; ***P0.001; ****P0.0001.

We strongly encourage authors to present confidence intervals (instead of P-values) in tables and text. Confidence intervals should be put in square brackets, separated by a comma not a dash.

The reference category should always be labelled ”Reference” (not 'ref').

Figures: authors' original artwork will be used; labelling should be in Calibri typeface so that after reduction it is no smaller than 8pts; symbols and lines should be distinct after reduction; histograms should be black, white or hatched in distinctive ways; background rules should not be used. Legends for figures should be typed on a separate sheet. In the full-text online edition of the journal, figure legends may be truncated in abbreviated links to the full-screen version. Therefore, the first 100 characters of any legend should inform the reader of key aspects of the figure. Full details of submission of figures in electronic format are available at http://authorservices.wiley.com/bauthor/illustration.asp

Artwork: It is the policy of Paediatric and Perinatal Epidemiology for authors to pay the full cost for the reproduction of their colour artwork. Therefore, please note that if there is colour artwork in your manuscript when it is accepted for publication, Wiley-Blackwell require you to complete and return a colour work agreement form before your paper can be published. Once completed, please return the form to the Production Editor at ppe@wiley.com. Any article received by Wiley-Blackwell with colour work will not be published until the form has been received.

Acknowledgements (including details of funding) should be placed at the end of the text.

References in the text should be referred to by a superscript number after the punctuation. The list of references at the end of the paper should be listed in the order in which they appear in the text. Note that journal names should be spelt out in full, and both the beginning and ending page numbers should be listed in full. References to personal communications, unpublished data or manuscripts “in preparation” should not be included. If essential, such material may be incorporated at the appropriate place in the text. The style should be as follows:

For articles, give authors' names followed by initials, full title of the article, full name of journal, year of publication, volume number, first and last relevant page numbers. List all authors and if the number exceeds six give the first six, followed by et al.

For books, give authors' names followed by initials, title of chapter/article, title of book preceded by 'In:', 'Editor(s):' followed by name(s) and initial(s), place of publication, publisher's name, year of publication, first and last relevant page numbers.

Proofs will be sent via E-mail as an Acrobat PDF (portable document format) file. They should be returned to the publisher within 3 days of receipt. Major alterations to the text and illustrations are only allowed in exceptional circumstances and the additional cost may be charged to the author.

The following house style is used:

• Birthweight not birth weight; stillbirth not still birth
• Breast feeding (noun) not breastfeeding; and breast-feeding mothers (adjective)
• Preterm or low birthweight never premature
• Confidence intervals not confidence limits
• Multivariable not multivariate, for regression models with a single outcome variable
• Parity to refer to the number of viable previous pregnancies. Definitions vary - always define the term in the methods. Use parity 0 if the pregnant or delivering woman has had no previous viable pregnancies, and refer to her as a primipara (plural primiparae). A woman who has had at least one prior viable pregnancy is a multipara (plural multiparae).
Race, ethnicity and nationality
When race, ethnicity or nationality are identified as research variables, the authors should make clear the purpose for using such variables. Authors should describe their methods of definition and classification of racial, ethnic or national groups. Ethnocentricity should be avoided. For example, in choosing a reference group, it should not be assumed that the majority racial, or ethnic group is necessarily the best choice. Care should be taken to explain the choice of referent. Limitations of race, ethnicity and nationality data and measurement should be clearly stated. Known or potential causes of the observed differences between groups should be explored and discussed.

Supporting Information
Publication in electronic formats has created opportunities for adding details or whole sections in the electronic version only. Authors need to work closely with the editors in developing or using such new publication formats. Supporting Information, such as data sets or additional figures or tables, that will not be published in the print edition of the journal, but which will be viewable via the online edition, can be submitted. It should be clearly stated at the time of submission that the Supporting Information is intended to be made available through the online edition. If the size or format of the Supporting Information is such that it cannot be accommodated on the Journal's website, the author agrees to make the Supporting Information available free of charge on a permanent website, to which links will be set up from the Journal's website. The author must advise Wiley Blackwell if the URL of the website where the Supporting Information is located changes. The content of the Supporting Information must not be altered after the paper has been accepted for publication. The availability of Supporting Information should be indicated in the main manuscript by a paragraph, to appear after the References, headed 'Supporting Information' and providing titles of figures, tables, etc. In order to protect reviewer anonymity, material posted on the author's website cannot be reviewed. The Supporting Information is an integral part of the article and will be reviewed accordingly.
