Dietary Assessment Methods in Surveillance Systems Targeted to Adults: A Literature Review

Abstract

Accurate and reliable evaluation of dietary consumption is essential for understanding individual dietary profiles. Proper dietary practices should provide sufficient amounts of both macronutrients and micronutrients for leading a healthy life. Choosing the best dietary assessment method for a certain objective leads to greater evidence for effective nutrition projects, policies, and programs. This review provides a clear understanding of dietary diversity assessment methods and the problems associated with choosing the best method. The resource guide aims to improve the quality and accuracy of nutrition information and provides a description of its applications, validity, strengths, and limitations. The databases searched for relevant papers for this review were Science Direct, Google Scholar, PubMed, Hindawi, Web of Science, Cochrane Library, etc. The review focused on collecting data from the last ten years of published articles, and duplicate papers were excluded from the database. Assessment methods described and compared in this study were the 24-hour recall method, food frequency questionnaires (FFQs), food records (FRs), quantitative food frequency questionnaires (QFFQs), non-quantitative food frequency questionnaires (Non-QFFQs), semi-quantitative food frequency questionnaires (SQFFQs), weighed FRs, and estimated FRs. In conclusion, this study highlights the need for a surveillance system for adults that collects comprehensive dietary information using standardized techniques and minimizes bias. This review’s extensive information can help national authorities choose appropriate protocols for their own dietary assessment surveys.
