सारांश	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 Maternal Diet Quality Index (MDQI) is a composite measure of maternal nutrition that evaluates diet quality during pregnancy and postpartum using a scored framework. Adapted from general population dietary quality indices, the MDQI emphasizes nutrients critical for fetal development and maternal health: folate, iron, calcium, protein, and micronutrient-rich foods. Use in research and clinical nutrition assessment to characterize maternal diet quality and its associations with pregnancy outcomes and lactation.
