Dietary assessment methodology and reporting in Pacific Island research: a scoping review protocol

This scoping review aims to identify and describe the methods used to collect and analyze dietary intake data in residents of Pacific Island countries.

Dietary assessment explores associations between dietary factors and health outcomes. In regions, including the Pacific Islands, where diet-related, non-communicable diseases are increasing, this is a growing area of research. As this information is used to inform food and nutrition policies and practice, accurate collection, analysis, and interpretation of dietary assessment data relies on robust methods. A greater understanding of how nutrition studies are designed can strengthen the evidence on nutrition and health in Pacific Island settings and inform future research approaches.

The scoping review will consider studies published in peer-reviewed journals, including quantitative and qualitative study designs and gray literature, including government reports, research and technical reports, theses and dissertations that measure and/or assess dietary intake in resident populations of the Pacific Island member countries of the Secretariat of the Pacific Community: American Samoa, Commonwealth of the Northern Mariana Islands, the Cook Islands, the Federated States of Micronesia, French Polynesia, Guam, the Independent State of Papua New Guinea, the Independent State of Samoa, the Kingdom of Tonga, New Caledonia, Niue, Pitcairn Islands, the Republic of Fiji, the Republic of Kiribati, the Republic of the Marshall Islands, the Republic of Nauru, the Republic of Palau, the Republic of Vanuatu, Solomon Islands, Tokelau, Tuvalu, and Wallis and Futuna.

There will be no time limit and searches will be conducted in PubMed, CINAHL, CABI, Scopus, Cochrane Library, and Web of Science. Results will be limited to English-language articles. Data will be extracted independently by two reviewers into a charting table. Results will be presented graphically and with tables accompanied by a narrative summary.
