The quality of the paper is not assessed at this point. The Editor-in-Chief (EIC) checks that the paper is appropriate for the journal and is sufficiently original and interesting. If not, the paper may be rejected without being reviewed any further. The handling editor sends invitations to 2 reviewers who will conduct a thorough review of the manuscripts double-blind (the authors name (s) and affiliation (s) is/are removed before sending out and the author (s) do not know the reviewer). An initial 21 days (subject to extension) is given to the reviewers to review the manuscripts and make recommendations using the journal reviewers’ guide. Based on the recommendation of the reviewers, the manuscript is sent to the corresponding author for revision. After the authors have revised the manuscript, a decision is taken by Editor-in-Chief whether the manuscript will be accepted/needs further revision/rejected based on the reviewers’ recommendation. The final decision is taken by the EIC. After which, authors are asked to pay an article-processing charge (APC) as determined by the editorial board if their manuscript was accepted for publication.

Duties of Editors

Decision on the Publication of Articles: 

The Editor-in-chief (EIC) of the Journal of Dietitians Association of Nigeria is responsible to make the decision regarding the publication of submitted articles. The EIC may be guided by the policies of the journal's editorial board and subjected to such legal requirements. The Editor is authorized to carry out the decision in consultation with reviewers and editorial board members.

Fair play: 

The manuscripts should be evaluated solely on their intellectual merit without regard to authors' race, gender, sexual orientation, religious belief, ethnic origin, citizenship, or political philosophy.


The Editor and editorial staff must not disclose any information about a manuscript which is submitted to the journal to anyone other than the corresponding author, reviewers, other editorial advisers, and the publisher, as appropriate. The editor must ensure the integrity of double-blind peer-review and should not disclose the identity of the reviewers to the authors of that manuscript, and vice versa.

Disclosure and conflicts of interest: 

Unpublished materials disclosed in a submitted manuscript must not be used by the editor or reviewer or anyone else who has a view of the manuscript while handling it in his or her own research without the express written consent of the author.

Duties of Reviewers

Contribution of Peer Review: 

Peer review assists the editor in making editorial decisions and editorial communications help the author to improve his paper.


If a selected reviewer feels unqualified to review an article he/she should notify the Editor-in-Chief and should not take part in the review process. Reviews will be expected to be professional, honest, courteous, prompt, and constructive, their judgment should be objective.


Manuscripts assigned to a reviewer must be treated as confidential documents. The manuscript(s) must not be shown to or discussed with, others except as authorized by the Editor in Chief.

Standards of Objectivity: 

Reviews should be conducted objectively. There shall be no personal criticism of the author. Reviewers should express their views clearly with supporting arguments.

Acknowledgment of Sources:

Reviewers should mark the uncited work that is published previously. Authors are expected to provide the proper citation for each statement that is quoted from a previously published work. A reviewer should inform the EIC of any substantial similarity between the manuscripts assigned him for review and the other previously published paper of which they have personal knowledge or they have found the similarity during the review process.

Confidentiality: Information or ideas obtained through peer review must be kept confidential and not used for personal advantage.

Conflict of Interest: Reviewers should not review manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.

Duties of Authors

Reporting standards: 

Authors of the original research article must present accurate data of work performed during their research. Authors are also expected to discuss the objective of their work and the significance of their results. An article should contain sufficient information and references to ensure the reproducibility of the work. Fraudulent or knowingly inaccurate statements are considered unethical behaviour and are unacceptable.

Data Access and Retention: 

Authors may be asked to provide the raw/supplementary data for a paper that is under editorial review. The authors should be prepared to provide the public access to these data (if practicable) and to retain such data for a reasonable time after the publication.

Originality and Plagiarism:

 Authors should ensure the originality of their content while preparing a manuscript draft. In case the authors have used the work and/or words of others this must be appropriately cited or quoted. Articles submitted to JDAN will be screened for plagiarism using plagiarism detection software. In case, the similarity index exceeds 20% excluding the references, during the review/editorial process, such manuscript(s) will be required to be revised/rejected if the revision did not meet up with less than 20% similarity index. If the plagiarism is proven after publication, such manuscript(s) will be retracted from the journal and an appropriate announcement will be placed in this regard.

We can also consider appropriate action against authors depending upon the seriousness of the case which includes;

Debarring the authors from publication in the future.

  1. Such incidents shall be brought to the notice of the author's funding agencies, author's institutions (place of works), and to the original authors whose work has been plagiarized.
  2. COPE flow charts will also be considered while dealing with plagiarism complaints.
  3. Suspected plagiarism in a submitted manuscript
  4. Suspected plagiarism in a published manuscript

Redundant or duplicate submission/publication

Duplicate or redundant submission is the same manuscript (or the same data) that is submitted to different journals at the same time. International copyright laws, ethical conduct, and cost-effective use of resources require that readers can be assured that what they are reading is original. An author should not publish manuscripts that describe the same concept or present similar data, in more than one journal. Submitting the same manuscript to multiple journals constitutes unethical publishing behaviour and is unacceptable and all such articles will be rejected immediately. In case the editor was not aware of the violation and the article has been published, a notice of the duplicate submission and the ethical violation will be published.

Authorship of the Paper and corresponding author: 

Authorship of an article should be based only on substantial contributions to each of the four components mentioned below:

  1. Concept and design of study or acquisition of data or analysis and interpretation of data;
  2. Drafting the article or revising it critically for important intellectual content and final approval of the version to be published.
  3. Each contributor should have participated sufficiently in the work to take public responsibility for appropriate portions of the content of the manuscript.
  4. The order of naming the contributors should be based on the relative contribution of the contributor towards the study and writing the manuscript and/or as agreed by the authors.

Corresponding Author

The corresponding author is the author responsible for communicating with the journal for publication. The corresponding author should ensure that no inappropriate contributors are listed as co-authors in the paper. All the co-authors should check the final draft of the manuscript before submitting it to the journal.

 Publishing Ethics

Monitoring: The EIC must ensure to establish the mechanism for monitoring and safeguarding of publishing ethics. All the complaints received from the reviewers or the authors or anybody else should be taken into proper consideration and appropriate action should be taken promptly for such complaints.

Retraction & Corrections: The published articles will be retracted if there is clear evidence that the findings are unreliable. The retraction can be a result of scientific misconduct or honest error. To maintain the integrity of the scientific record, the retracted article will not be removed from the journal's website, however, a notice of retraction will be posted and is made freely available to all readers. Retraction can be published by the authors or the editor or the publisher. In rare cases involving legal infringement, the Publisher may remove an article. Bibliographic information about the article will be retained to ensure the integrity of the scientific record. We follow the COPE guidelines in such cases. Sometimes it may be necessary to publish corrections/erratum in an article published in the Journal to maintain the integrity of the academic record. Appropriate notice regarding the correction will be placed and made freely available to the readers. We are always willing to publish corrections, clarifications, retractions, and apologies when needed.

Article withdrawal: 

We expect our authors to comply with best practices in publication ethics as well as in the quality of their articles. To avoid withdrawal of articles we sincerely request the corresponding author to undertake the issues related to authorship, publication ethics, and accurateness of data and results at the time of submission of the manuscript.

If an article is found to violate the ethical publishing guidelines of the journal such as duplicate submission, fraudulent data, plagiarism, false claim of authorship, etc. the article will be withdrawn by the journal. In case the article is under the ‘Online first’ stage the journal will remove the article from the website and an appropriate note for article withdrawal will be posted.

No response from the authors to journal communication after review and provisional acceptance is also considered as withdrawal of the article.

Preclude business needs from compromising intellectual and ethical standards: 

We believe that the funding agencies and sponsors should not be able to influence the author's findings or the decision-making. The editor should maintain the integrity of the academic record, preclude business needs from compromising intellectual and ethical standards, and always be willing to publish corrections, clarifications, retractions, and apologies when needed.

Ethics approval and consent to participate

Manuscripts reporting studies involving human participants, human data, or human tissue must: include a statement on ethics approval and consent (even where the need for approval was waived), include the name of the ethics committee that approved the study, and the committee’s reference number if appropriate. In addition, studies involving animals must include a statement on ethics approval. If your manuscript does not report on or involve the use of any animal or human data or tissue, please state “Not applicable” in this section.

Conflicts of interest

Authors must declare all sources of support for the research and any association with a product or subject that may constitute a conflict of interest.

Consent for publication

If your manuscript contains any individual person’s data in any form (including individual details, images or videos), consent for publication must be obtained from that person, or in the case of children, their parent or legal guardian. All presentations of case reports must have consent for publication.

You can use your institutional consent form if you prefer. You should not send the form to us on submission, but we may request to see a copy at any stage (including after publication). 

Availability of data and materials

All manuscripts must include an ‘Availability of data and materials statement. Data availability statements should include information on where data supporting the results reported in the article can be found including, where applicable, hyperlinks to publicly archived datasets analysed or generated during the study. By data, we mean the minimal dataset that would be necessary to interpret, replicate and build upon the findings reported in the article. We recognize it is not always possible to share research data publicly, for instance when individual privacy could be compromised, and in such instances, data availability should still be stated in the manuscript along with any conditions for access.
