About the Project and Team

Motivation and Aims

This project aims to collect dietary quality data in the general adult population across countries worldwide, and to provide the tools for valid and feasible diet quality monitoring within countries. The project enables the collection of consistent, comparable dietary data across countries for the first time.


The Global Diet Quality project provides two main global public goods:

1. Diet Quality Questionnaire (DQQ) module that takes 5 minutes to implement, adapted for each country. The DQQ is an internationally standardized survey instrument that works universally while also capturing local realities, and can be used to interpret diet quality within and across countries. Country-adapted DQQ modules can be easily implemented and analyzed by any survey team with an interest in gathering information on diet quality. The availability of these low-burden tools is intended to facilitate and catalyze diet quality monitoring in countries, and across sectors.


2. Data on diet quality across countries. The Gallup World Poll is implementing the DQQ, starting with a first phase of 56 countries in 2021-2022. A suite of diet quality indicators will be reported, capturing dietary adequacy and dietary risk factors for noncommunicable diseases (NCDs). The data will enable monitoring of trends, and comparisons across different age, gender, income, and urban/rural populations. Furthermore, DHS (the Demographic and Health Surveys) is implementing selected questions of the DQQ for women, and aligned questions for infants and young children.
