Background: Diet quality during infancy can influence nutrient intake and ultra-processed foods (UPFs) consumption throughout later childhood.
Objectives: This study investigated the predictive validity of Infant Diet Quality Index (IDQI) scores from 0 to 1 y of age and consumption of select nutrients and UPFs at different time points in low-income children aged 2-5 y.
Methods: Dietary surveys and 24-h dietary recalls collected between ages 0 and 12 months from 2613 Special Supplemental Women, Infants, and Children Infant Toddler Feeding Practices Study-2 participants were used to assess infant diet quality by final IDQI score ranging from 0 (nonadherence to dietary guidelines) to 1 (complete adherence to guidelines).
Objective: To describe two low-burden diet quality scores and evaluate their performance in reflecting the dietary share of the least and most processed foods defined within the Nova food system classification.
Methods: This cross-sectional study included data from the NutriNet-Brasil cohort. Participants answered the Nova24hScreener, a 3-minute self-administered questionnaire measuring the consumption of a set of foods on the day before.
