摘要	The IYCF assessment is a set of core indicators developed by WHO and UNICEF to measure the prevalence of key feeding practices in children aged 0–23 months. The indicators track six essential markers: exclusive breastfeeding in infants under 6 months, continued breastfeeding in the second year, timely introduction of complementary foods at 6–8 months, and adequate dietary diversity and meal frequency by 6–23 months. These indicators are foundational for monitoring nutrition outcomes and evaluating maternal and child health programs worldwide.	The HEI-2020 is a composite score measuring diet quality based on adherence to the 2020–2025 Dietary Guidelines for Americans. Developed by USDA and the National Cancer Institute, the HEI evaluates 13 dietary components: adequacy of fruit, vegetables, grains, protein foods, dairy; moderation of saturated fat, added sugars, and sodium; and appropriate whole grain and polyunsaturated fat intakes. The HEI-2020 provides a single metric of overall diet quality suitable for population surveillance, research, and individual dietary assessment.
