요약	The Children's Dietary Questionnaire (CDQ) is a parent-proxy or child self-report food frequency questionnaire designed to assess usual dietary intake in children and adolescents aged 6–18 years. Developed by Rockett and colleagues at Harvard School of Public Health in the 1990s, it captures consumption of 60–120 common foods and beverages with frequency and portion size information. The CDQ enables estimation of daily energy, macronutrient, and micronutrient intakes and characterization of dietary patterns (e.g., prudent vs. Western diet).	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.
