Researchers evaluated the comparative performance of the Global Diet Quality Score (GDQS) against other diet metrics to capture nutrient adequacy and undernutrition. The GDQS performed comparably with the Minimum Dietary Diversity–Women indicator in capturing adequacy outcomes. Given limited data on noncommunicable disease (NCD) outcomes and the cross-sectional study design, prospective studies should assess GDQS performance in capturing NCD outcomes.
