Development, validation and utilisation of dish-based dietary assessment tools: a scoping review

Area of Science:

• Nutrition science
• Dietary assessment methodology
• Public health research

Background:

• Dish-based dietary assessment tools are crucial for evaluating dietary intake, particularly in diverse populations.
• Existing tools are predominantly developed and utilized for Asian-origin populations.
• Understanding the development, validation, and utilization of these tools is essential for accurate dietary research.

Purpose of the Study:

• To conduct a scoping review of existing evidence on the development, validation, and utilization of dish-based dietary assessment tools.
• To identify the populations for which these tools have been developed.
• To evaluate the validation status and application of these tools in research.

Main Methods:

• A systematic literature search was conducted using PubMed and Web of Science databases.
• Seventy-four eligible publications were identified, from which twelve dish-based dietary assessment tools were extracted.
• Tools were analyzed for their development process, validation methods (including self-reported data and biomarkers), and utilization in studies.

Main Results:

• Twelve dish-based dietary assessment tools were identified, developed for various Asian populations (Koreans, Bangladeshis, Iranians, Indians/Malays/Chinese, Japanese, Chinese Americans).
• Most tools (10/12) were dish-based Food Frequency Questionnaires (FFQs). Validation against self-reported dietary information and concentration biomarkers showed significant differences in energy and nutrient intake in several studies.
• Correlation coefficients for energy and nutrients varied, with median coefficients ranging from 0.12 to 0.77. These tools were predominantly used to assess diet-disease relationships.

Conclusions:

• Dish-based dietary assessment tools have been exclusively developed and applied to Asian-origin populations.
• Further validation studies, particularly those incorporating biomarkers, are recommended to ascertain the broader applicability of these tools.
• The findings highlight the need for continued research into the development and validation of culturally appropriate dietary assessment tools for diverse global populations.
