Authors’ quick submission checklist

(※ Please include the checklist when submitting the manuscript to the submission site.)

Category		Items to review	Check
Title page	1. Title	- Spelling and typographical errors in paper titles - Titles should be written in sentence case, with only the first word of the text and proper nouns capitalized. The study design should be included in the title or subtitle. e.g., Development and Effectiveness Evaluation of the STEAM Education Program on Food Groups for Kindergarteners -> Development and effectiveness evaluation of the STEAM education program on food groups for kindergarteners: a non-randomized controlled study e.g., Program Evaluation using the RE-AIM Framework: A Systematic Review and Application to a Pilot Health Promotion Program for Children -> Evaluation of the pilot health promotion program for children: a systematic review
	2. Author Information	- Include all author titles and affiliations, and indicate the position before the affiliation
	3. Submission	- The title page, the copyright transfer agreement, and IRB approval are all included when submitting your paper to the submission site by uploading them to the ‘Attachment’ section. - Remove the cover page including author information from the submitted paper before submitting
	4. ORCID	- ORCID should be stated for all authors e.g., Gildong Hong: https://orcid.org/0000-0000-0000-0000
	5. Funding	e.g., This research was supported by a grant from the National Research Foundation of Korea (Grant No. 000). - When there is no funding associated with the manuscript, "none" should be stated.
Abstract	1. Structure	- Objectives-Methods-Results-Conclusions
	2. Keywords	- Three to five keywords are recommended with one or two words except for technical terms. - The terminology should be listed, in principle, in MeSH (www.nlm.nih.gov/mesh/MBrowser.html). - Keywords are written in lowercase letters except for proper nouns, and keywords are separated by a semicolon (;).
	3. Abbreviations	- Abbreviations should only be used if they are repeatedly used throughout the abstract. If an abbreviation is not used after it has been defined, use the full name instead - Define an abbreviation the first time it appears in the abstract
Main body	1. Structure	- Title page, Abstract, Introduction, Methods (including ethics statement), Results, Discussion, Conclusion, Conflict of Interest, Acknowledgments, Data Availability References, Tables, and Figures - Upload tables and figures as a single file and do not separate them
	2. Statistical software	- Enter the correct type and version of statistical software e.g., IBM SPSS Statistics 25 (IBM Corporation, Armonk, NY, USA) e.g., SAS 9.4 (SAS Institute, Cary, NC, USA)
	3. Ethics Statement	- Authors should present an “Ethics Statement” immediately after the heading “Methods”. In case of reviews, research notes and educational materials, “Ethics Statement” should be presented after introduction section e.g., The informed written consent was obtained from each participant. The study protocol was approved by the Institutional Review Board of *** (approval number: ***). *IRB approval statement will be included in the final version, but do not include specific IRB information (e.g., institution name) when submitting. e.g., Obtainment of informed consent was exempted by the institutional review board.
	4. Conflict of Interest	- Conflict of interest must be stated. e.g., There are no financial or other issues that might lead to conflict of interest. e.g., Gildong Hong has been an editor since 2021. However, he was not involved in the review process of this manuscript. Otherwise, there was no conflict of interest. *Author information will be included in the final version but do not include it when submitting.
	5. Acknowledgments	- List individuals who contributed to the writing or research, but do not meet the criteria for authorship. e.g., We thank the physicians who performed the sample collection. *This information will be included in the final version, but do not include it when submitting.
	6. Data Availability	- Authors should provide a data availability statement. Providing access to research data is optional. e.g., The data that support the findings of this study are openly available in [repository name e.g “KNHANES”] at http://doi.org/[doi].
	7. References	- Notation method: [1], [2, 5], [15-20], etc. without spaces before square brackets, when adding commas between references, add a space after commas. e.g., research on something[1] or Kim & Lee's research[2, 5] - References in the text should be listed in numerical order - The number of citations for the type of dissertation should not exceed 3. - The total number of references should be no more than 50 - Verify that the reference adheres to the KJCN guidelines
	8. Other indications such as units	- Write numbers and units with a space (50 kg, 600 kcal), but attach % and ℃. - g/dl (X), g/dL (O) - When indicating P-value, use capital, italic P: e.g., P-value - Use a dash ‘-’ to indicate a range of numbers: e.g., 20-25 - Use comma notation to separate thousands (this also applies to text and tables): For example, 65,450,000.
	9. Tables, figures	- Capitalize only the first letter of table and figure titles - Capitalize only the first letter of variables in the table - Use lowercase ‘n’ in tables and figures. - Additional checklists for tables and figures can be found in the section below.

^*Examples shown in the tables are based on recent publication, 2024.

Guideline for Tables and figures

Please adhere the following guidelines for tables and figures.

• 1. To indicate the total number of items outside of the table’s body, include it in parentheses at the end of the table’s title. For example, “Sociodemographic characteristics of children (n = 80)”
• 2. The table heading should provide a descriptive title for the values presented, rather than simply using “Mean ± SD” as the title.
• 3. When describing the contents of the table in the text:
  • ① To present an average value, use Mean ± SD or Mean ± SE, and be mindful of spacing (e.g., 22.0 ± 2.3, with a space before and after the ‘±’ symbol)
  • ② Units should be written in parentheses within the table (e.g., Energy (kcal/day)) instead of next to it (Energy, kcal/day)
• 4. Footnotes or legends explanations for tables or figures should be written in English
• 5. The footnotes or legends should be arranged in the following order: Values displayed as statistical outcomes, statistical analysis method, indication of significance, etc.
  • ① The presentation of values of statistical outcomes, such as n (%), Mean ± SD, n (%) or Mean ± SD, etc, are displayed in the first line of the footnote without comment numbers.
  • ② Statistical analysis method and significance indication - Both statistical analysis methods and significance are discussed. - Post-hoc analysis results can only be presented when the ANOVA test yields significant results.
  • ③ The full name of any abbreviations used in the title or table body should be provided in the footnote.
  • ④ Any other content that requires explanation should be accompanied by corresponding comment numbers, following the submission guidelines. Verify that the comment numbers match the numbers indicated in the table body.
