claimThe food groups and scoring system for the Global Diet Quality Score (GDQS) were refined through analyses of multiple cross-sectional and cohort data sets.
measurementThe Global Diet Quality Score (GDQS) and GDQS- metrics categorize high-fat dairy and red meat as food groups that are included in the metrics but are considered unhealthy in excessive amounts.
claimThe Global Dietary Quality Score (GDQS) is a food-based metric that incorporates a more comprehensive list of food groups than most existing diet metrics and provides a simple means of scoring.
claimThe global version of the Global Diet Quality Score (GDQS) was developed for population-level use using data sets from Africa, India, China, Mexico, and the United States.
claimConstructing the Global Diet Quality Score (GDQS) requires intermediate data complexity, but does not require food composition data, similar to the Minimum Dietary Diversity for Women (MDD-W) and the GDR Score.
claimThe Global Diet Quality Score (GDQS) requires semi-quantitative data to distinguish intake quantity categories for each of its 25 food group components.
claimThe Global Dietary Recommendations (GDR) Score is based on non-quantitative food group recall data, whereas the Global Diet Quality Score (GDQS) is based on semi-quantitative data.
claimThe Global Dietary Recommendations (GDR) Score and the Global Diet Quality Score (GDQS) were developed for adults, though they may be evaluated for other demographic groups in the future.
claimNeither the Global Dietary Recommendations (GDR) Score nor the Global Diet Quality Score (GDQS) requires the use of food composition data for tabulation.
claimThe development of the Global Diet Quality Score (GDQS) involved selecting food groups based on a literature review of relationships between food group intakes and health outcomes, similar to the development of the Alternative Healthy Eating Index (AHEI).
measurementThe Global Diet Quality Score (GDQS) and GDQS- metrics categorize food groups into healthy and unhealthy components, where items like processed meat, refined grains, sweets, sugar-sweetened beverages, juice, white roots/tubers, and deep-fried foods are considered unhealthy in excessive amounts.
referenceBromage et al. (2021) assessed the construct validity of the Global Diet Quality Score (GDQS) relative to nutrient adequacy, biomarkers for non-communicable disease (NCD) risk, metabolic syndrome, and the incidence of type 2 diabetes.
claimUnlike the GDR Score, the Global Diet Quality Score (GDQS) is not based on adherence to existing or current global dietary guidance.

referenceHe Y et al. (2021) published a study in J Nutr applying the Global Diet Quality Score to Chinese adults to evaluate the double burden of nutrient inadequacy and metabolic syndrome.
measurementThe Global Diet Quality Score (GDQS) is associated with higher nutrient adequacy, mid-upper arm circumference, venous hemoglobin, and serum folate levels among urban and rural Ethiopian adults, according to Bromage et al. (2021b).
referenceFung TT et al. (2021b) published a study in J Nutr finding that a higher Global Diet Quality Score is associated with less 4-year weight gain in US women.
referenceRestrepo-Mesa et al. (2023) evaluated the effect of an action-research nutrition intervention on the Global Diet Quality Score of Colombian adolescents.
claimDamigou et al. (2023) measured diet quality and the consumption of healthy and unhealthy foods using the Global Diet Quality Score (GDQS) in relation to cardiometabolic outcomes in the ATTICA Epidemiological cohort study (2002–2022).
measurementThe Global Diet Quality Score (GDQS) is inversely associated with nutrient inadequacy, low mid-upper arm circumference, and anemia in rural adults across ten Sub-Saharan African countries, as reported by Bromage et al. (2021c).
referenceThe abbreviation GDQS stands for Global Diet Quality Score.
referenceFung TT et al. (2021a) published a study in J Nutr finding that a higher Global Diet Quality Score is inversely associated with the risk of type 2 diabetes in US women.
referenceMoursi M, Bromage S, Fung TT et al. (2021) published a study in the Journal of Nutrition titled 'There’s an app for that: development of an application to operationalize the global diet quality score'.
referenceNorde MM, Bromage S, Marchioni DML et al. (2024) published a study in Nutrition Journal titled 'The global diet quality score as an indicator of adequate nutrient intake and dietary quality – a nation-wide representative study'.
claimBromage et al. (2021a) developed and validated the Global Diet Quality Score (GDQS), a novel food-based metric for assessing diet quality.
How do the indices based on the EAT-Lancet recommendations ... medrxiv.org May 14, 2024 3 facts
measurementThe total Global Diet Quality Score (GDQS) ranges from 0 to 49 points and is divided into two sub-scores: GDQS+ (sum of healthy food components, range 0-32) and GDQS- (unhealthy or over-consumed food components, range 0-17).
measurementQuantitative dietary indices demonstrate greater validity by correlating closely with dietary quality indicators such as the Global Diet Quality Score (GDQS) and the Comprehensive Diet Quality Index (cDQI) (ρ < 0.69).
measurementThe six indices based on EAT-Lancet recommendations are positively associated with the Global Diet Quality Score (GDQS) (correlation coefficients between 0.19 and 0.52) and the Comprehensive Diet Quality Index (cDQI) total scores (correlation coefficients between 0.32 and 0.69).

claimMetrics constructed using both healthy and unhealthy food groups, such as the Global Dietary Recommendations (GDR) score and the Global Diet Quality Score (GDQS), showed relatively less discriminatory capacity across country income classifications compared to their respective submetrics or the Food Group Diversity Score (FGDS).
referenceThe study evaluated several healthy diet metrics, including the Food Group Diversity Score (FGDS), Minimum Dietary Diversity for Women indicator, Global Diet Quality Score (GDQS) and its submetrics (GDQS+ and GDQS-), Global Dietary Recommendations (GDR) score and its submetrics (NCD-Protect and NCD-Risk scores), and the All-5 indicator.
