JOURNAL STYLE

For authoritative guidance on style, usage, and spelling, the Journal uses the following resources: AMA Manual of Style, 10th ed; Dorland's Illustrated Medical Dictionary, 30th ed; and Merriam Webster's Collegiate Dictionary, 11th ed. Other resources for laboratory values, race and ethnicity, and Dietary Reference Intakes are listed under those sections.

Software Citations Software developers are cited parenthetically in the text after the first mention of a software package. Software citations should include the name, version number, and release date of the software as well as the name of the software developer. [Example: All statistical analyses were conducted using SAS (version 9.1.3, 2006, SAS Institute Inc).] If software incorporates a nutrient database, provide information in the text about the database. This should include the release date for the database, a description of substantial modifications made to the database, and an explanation of how missing nutrient data for foods were handled (ie, indicate whether values were extrapolated and evaluate the effect of any missing values on dietary totals for the nutrients of interest). Do not include information about software or databases in the list of references or the abstract.

Footnotes in Text Footnotes should be kept to a minimum and indicated consecutively, with superscript symbols (*, †, ‡, §, etc), throughout the text. Double space footnotes on a separate sheet of paper. Footnote citations should read from top left to bottom right. All text in the footnote section of a table should be properly cited in the table. All abbreviations and acronyms in a table or figure must also be footnoted with the correct expansion.

Use of NCP and NCPT For topics that are addressing dietetics and nutrition care provided by dietetics practitioners, authors should use the Nutrition Care Process (NCP) as a framework for describing the nutrition assessment, nutrition diagnoses, nutrition intervention, and nutrition monitoring/evaluation that was included in the research and use the Nutrition Care Process Terminology (NCPT) to describe the aspects of care within each of the above steps. Additional information on the NCP and NCPT is available under "Resources for Health Practitioners" on the Academy's website.

Credentials Bylines are a general indicator for indexing purposes of authors' contribution to the published work. Journal style is to list the highest academic degree(s) of each author followed by any/all credentials and certifications from the Commission on Dietetic Registration (eg, RD, RDN, DTR, CSP, CSR, CSG, CSO, CSSD, FAND); and if desired by the author, state licensure (LD, LDN, or CDN) and fellowships. If an author has a doctorate, master's level degrees should not be included unless the master's degree is in a different or specialized field. Academic degrees below the master's level are omitted unless they are the highest obtained degree. For credentials issued outside the United States, indicate the country of origin in a footnote.

Note: For articles that relate to specialist or advanced practice credentials, which appear in the "From the Academy" section, some author credentials may relate to specialist or advanced practice credentials obtained from another organization, and these can be included in the author byline. Non-CDR credentials received by the RDN/DTR author in these "From the Academy" articles will be verified by the Quality Management Team (for SOP/SOPP in focused areas of practice) or the HOD Governance Team (for Academy of Nutrition and Dietetics position or practice papers). These credentials include: CDE, BC-ADM, CNSS/CNSD, CHES, CLC, SNS, and others, which authors may inquire about at the time of submission. Authors from other fields such as nursing, medicine, surgery, etc., are asked to provide verification at the time of submission regarding their advanced practice credentials (these include, but are not limited to APRN-BC, CIC, NP, OCN, RM(C), RPh-BC-ADM).

Numbers Numbers below 10 are spelled out unless followed by a unit of measure or a percentage. Express all numbers 10 or larger as Arabic numerals. Numbers that begin a sentence are always spelled out. The number of significant digits reported should be realistic and supported by the original data (eg, 2,125 kcal, not 2,124.8 kcal; 105 lb, not 105.734 lb). For sample sizes smaller than 100, frequency must be given (eg, two of seven, not 29%); percent may also be provided if necessary. Also, do not include a decimal and zero after a whole percent number (Correct: 72%, Incorrect: 72.0%).

Abbreviations and Acronyms Abbreviate units of measure when used with numerals (5 g, 1,000 kcal). Chemical formulas should be written out, unless they are used to economize space in the column headings of a table; however, the formulas should be expanded in the footnotes. Always provide the complete form of an acronym the first time it is mentioned in the text (note that if an abbreviation has been spelled out in the abstract, it still must be spelled out in the text on first-time use). An acronym or abbreviation is permitted if it is used three or more times within the manuscript text. Avoid excessive use of acronyms and abbreviations. Avoid author-invented abbreviations and acronyms.

Laboratory Values All clinical laboratory values must be expressed in Conventional Units, (eg, lipids should be expressed in mg/dL) with Système International (SI) units in parentheses in the manuscript text, for example: triglycerides 100 mg/dL (1.13 mmol/L). Authors must provide the conversion factor to SI units as a footnote in tables and figures. The exception to this is the use of kilocalories; the Journal will continue to use kilocalories instead of kilojoules. The metric system is preferred for the expression of length, area, mass, and volume. A table of normal values in both Conventional and SI units and the appropriate conversion factors appears on Oxford University Press website. Authors should refer to this table when converting data and use it as a guide for choosing the appropriate number of significant digits.

Trade Names When specific products used in the research are referred to by a trade name, give the manufacturer's name parenthetically after the first mention. When possible use generic names for food and drugs. Registration or trademarks are not required.

Dietary Reference Intakes Authors must use the Dietary Reference Intakes (DRIs), not the 1989 Recommended Dietary Allowances. Information on the DRIs can be found through the Institute of Medicine. If for any reason an author wishes to report nutrient intakes without using the stated DRIs, intakes may be reported, but adequacy should not be assessed.

Personal Pronouns Personal pronouns (eg, I, our, we) should be used sparingly, if at all, in Journal submissions except Letters to the Editor.

Race and Ethnicity The Journal follows the guidelines set forth by the National Institutes of Health.

EDITORIAL PROCESSING AND PUBLICATION Article content is the authors' responsibility. Accepted manuscripts are copyedited to conform to Journal style and to meet space limitations. Authors should note that the editing process is separate from and occurs after the peer-review process. The corresponding author will receive an electronic proof of the article and have an opportunity to review editorial changes and to double-check accuracy of content, tables, and statistics before publication. However, a change made by copyeditors for style, grammar, and readability should not be altered by authors unless a scientific error has been introduced. Authors will be expected to review galleys promptly (within 4 business days of receipt). If the corresponding author is not available to receive or review proofs at any given time, a back-up should be identified and contact information provided to the editors.

Information regarding reprint orders will be sent along with author proofs from the Journal's publisher.

Embargo Policy/Articles in Press For the protection of each author's work, the Journal does not allow the unauthorized pre-publication of any materials slated for publication. All articles accepted for publication are posted online in their corrected format as Articles in Press, and are subject to embargo until such date the articles are available online. The timetable for online publication is approximately 8 weeks from acceptance.

Authors may track the status of their articles and sign up for Article in Press alerts on the Journal's website.

Authors wanting to coordinate press activity with their institutions should consult the contact provided in their proof communication to confirm embargo information.
