How Brazilian Schoolchildren Identify, Classify, and Label Foods and Beverages-A Card Sorting Methodology.

This study examined how Brazilian schoolchildren identified, classified, and labeled foods and beverages. Semi-structured interviews were conducted with 133 schoolchildren aged 7 to 10 years old from a public school located in southern Brazil in 2015. A set of cards with pictures of 32 food and beverage items from the web-based Food Intake and Physical Activity of Schoolchildren tool (Web-CAAFE) were used.

Two validity evidences of the ESQUADA and Brazilians' dietary quality levels.

Objective: Assess two validity evidences of the diet quality scale (ESQUADA) for the selection of items with better discrimination of the Brazilians' diet quality and propose a description in score levels.

Methods: Brazilian adolescents and adults residing in the country (n = 2,059) answered an online questionnaire with 52 items, shared on social networks and email lists between March and April 2018. Statistical tests were applied to analyze the validity and reliability of the instrument's evidence.

Changes in Dietary Patterns from Childhood to Adolescence and Associated Body Adiposity Status.

The aims of this study were to identify cross-sectional dietary patterns (DPs) in a representative sample of 7-10-year-old schoolchildren, to examine how scores for these DPs tracked over a time period of five years (from age 7-10 years to 12-15 years), and to investigate longitudinal associations between changes in DPs scores and changes in BMI (Body Mass Index) z-scores. Children aged 7-10-years were examined in 2007 ( = 1158) and a subset of the sample participated in a follow-up in 2012 ( = 458). Factor analysis (FA) was applied to derive DPs at baseline.
