Aims & Scope

Journal of Mother and Child (JMC)/Medycyna Wieku Rozwojowego, formerly known as Developmental Period Medicine/Medycyna Wieku Rozwojowego, is a quarterly, peer reviewed, Open Access journal published by the Institute of Mother and Child in Warsaw (Poland), dedicated to disseminating basic and applied research related to health of mother and child.

It is indexed in MEDLINE/PUBMED, Scopus, EBSCO, MNiSW, PBL (Polska Bibliografia Lekarska), Index Copernicus. The journal publishes original research papers, review articles, short communications, case studies. The language of submission is English.


Submission of the Manuscript

Manuscripts containing original material are accepted for consideration with the understanding that neither the article nor any part of its essential substance, tables, or figures has been or will be published or submitted for publication elsewhere. This restriction does not apply to abstracts or short press reports published in connection with scientific meetings. Copies of any closely related manuscripts should be submitted along with the manuscript that is to be considered by the Journal of Mother and Child (JMC)/Medycyna Wieku Rozwojowego. The Journal discourages the submission of more than one article dealing with related aspects of the same study.


The Journal of Mother and Child (JMC)/Medycyna Wieku Rozwojowego only accepts online submission of papers. The authors are encouraged to refer to the instruction on submitting their manuscript online.

During the online submission procedure, authors are asked to provide:

a) information on the prior or duplicate publication or submission elsewhere of any part of the work;

b) a statement of financial or other relationships that might lead to a conflict of interest or a statement that the authors do not have any conflict of interest;

c) a statement that the manuscript has been read and approved by all authors;

d) the name, address and telephone numbers and e-mail address of the corresponding author who is responsible for negotiations concerning the manuscript.

The manuscript must be accompanied by copies of any permission (see Permissions below) to reproduce already published material, to use illustrations or report sensitive personal information about identifiable persons.

All papers submitted to the Journal of Mother and Child (JMC)/Medycyna Wieku Rozwojowego are checked by the editorial office for conformance to the author and other instructions all specified below. Non-conforming manuscripts will be returned to authors. Before submission, please use this check list to avoid the most common reasons for non-conformity:

Use terms from the Medical Subject Headings (MeSH) list of Index Medicus when possible.

The main text should be divided into the following sections: Introduction, Methods, Results and Discussion. More information on the structure and content of these sections can be found in the Recommendations for the Conduct, Reporting, Editing, and Publication of Scholarly work in Medical Journals ( Relevant ethical issues should be discussed in the manuscript and necessary permissions and authorizations declared.

Keypoints should be presented in the form of 3 to 6 bulleted, short statements which give the main messages of the paper. Only one sentence per key point. Include at least one implication for public health policy and practice.

For the references, see the separate guidelines at the end of the author instructions. There is a limit of 40 references for original articles.

Type each table on a separate page, and provide a title for each. Abbreviations in tables should be explained. Place the tables at the end of the main document or upload them in a separate text file. Excel format is not accepted.

Do not indicate “statistical significance” with bold or otherwise altered font. If you use data from another published or unpublished source, obtain permission and acknowledge fully.

Figures should be professionally designed, using a well-known software package for standard personal computers. Three-dimensional figures are not allowed.

However, if the manuscript is accepted, .tif format is required.

Symbols, lettering, and numbering should be clear and large enough to remain legible after the figure has been reduced to fit the width of a single column, i.e. 7 cm. The figure legend should be provided in the submission system when uploading the figure, or at the bottom of the main document, and should not appear in the figure. If a figure has been published earlier, acknowledge the original source and submit written permission from the copyright holder to reproduce the material. If photographs of patients are used, their pictures must be accompanied by written permission to use the picture, whether the patient is identifiable or not.
