Association between sleep timing and meal and snack patterns in schoolchildren in southern Brazil.

This study aimed to identify meal and snack patterns and assess their association with sleep timing in schoolchildren. This is a cross-sectional study carried out in 2018/2019 with 1333 schoolchildren aged 7-14 years from public and private schools in Florianópolis, Brazil. Previous-day dietary intake data for breakfast, mid-morning snack, lunch, mid-afternoon snack, dinner and evening snack were collected using a validated online questionnaire.

Development and application of the Meal and Snack Assessment (MESA) quality scale for children and adolescents using item response theory.

Background: Meals differ in terms of food items and nutritional quality. The aim of the present study was to propose a scale to measure the meals quality of schoolchildren according to food processing degree, perform a preliminary evaluation of the scale's validity and reliability and apply the scale to a representative sample of schoolchildren in a city in southern Brazil.

Methods: A methodological study based on the generalized graded unfolding model (GGUM) of item response theory (IRT) with analysis of secondary data was carried out in 6,399 schoolchildren of 6-15y-old attending 2nd to 5th grades of public elementary schools in Florianópolis, Brazil, in 2013-2015 who answered the validated Food Intake and Physical Activities of Schoolchildren (WebCAAFE) questionnaire.

Temporal trend of food consumption markers, breakfast consumption and association with overweight/obesity in schoolchildren aged 7 to 10 years between 2007 and 2019.

Obesity has a multifactorial origin. Among the behavioural risk factors, excessive consumption of unhealthy foods, skipping breakfast and reduced physical activity stand out. The main objective of this article was to identify trends in dietary habits and their association with overweight/obesity over a 12-year period in schoolchildren aged 7 to 10 years in Florianópolis, southern Brazil.

Association between Sleep Timing, Being Overweight and Meal and Snack Consumption in Children and Adolescents in Southern Brazil.

Sleep timing is one of the dimensions of sleep that refers to the time of day when sleep occurs. It has been included in sleep-related research because of the potential associations between being overweight and the consumption of meals and snacks. This cross-sectional study aimed to investigate associations between sleep timing, meal and snack consumption and weight status in 1333 schoolchildren aged 7-14 years.

Methodological aspects and characteristics of participants in the study on the prevalence of obesity in children and adolescents in Florianópolis, Southern Brazil, 2018-2019: EPOCA study.

Purpose: To describe the methodological aspects and characteristics of the participants of the EPOCA survey.

Methods: The study was conducted with schoolchildren aged between seven to 14 years old from 30 schools in Florianópolis, Southern Brazil. Body mass, height, girths, and skinfold thicknesses were measured.

Is breakfast consumption among Brazilian schoolchildren associated with an ultra-processed food dietary pattern?

Omission of breakfast starts at school age and can be explained as a reflection of the independent behaviour acquired in this phase of life. Breakfast has been investigated for its association with healthier diet quality, but few studies have investigated this relationship in schoolchildren aged 7 to 13 years. The objective of this study was to assess breakfast consumption in schoolchildren aged 7 to 13 years and to examine associations with dietary patterns (DPs).

Most meal and snack patterns are stable over a 3-year period in schoolchildren in southern Brazil.

This study aimed to identify meal and snack patterns in Brazilian schoolchildren and assess their stability over 3 years. This is a repeated cross-sectional study carried out in 2013, 2014 and 2015 with 6353 schoolchildren aged 7-12 years from public schools in Florianópolis, Brazil. Previous-day food consumption data for six pre-defined meals (breakfast, mid-morning snack, lunch, mid-afternoon snack, dinner and evening snack) were collected using the validated Web-CAAFE (Food Consumption and Physical Activity of Schoolchildren) questionnaire.

Dietary patterns and cardiovascular risk factors among Brazilians: A population-based study in Viçosa, Minas Gerais.

Objective: The aim of this study was to identify dietary patterns (DPs) and analyze their association with cardiovascular risk factors including metabolic biomarkers and markers of inflammation and oxidative stress in a cross-sectional population-based study with 959 Brazilian adults from Viçosa.

Methods: Food consumption was assessed by food frequency questionnaire, and DPs were identified by principal component analysis. A self-administered questionnaire was applied to assess sociodemographic and behavioral variables.

Uric acid: A new marker for metabolic syndrome? Results of a population-based study with adults.

Background And Aims: Recently, studies have shown a positive association between serum uric acid (UA) and metabolic syndrome (MS). To evaluate the predictive capacity and the association of serum UA with pre-MS and MS, by sex, in adults.

Methods And Results: Cross-sectional study with 932 adults, of both sexes, from Viçosa, Minas Gerais (MG), Brazil.

Meal and snack patterns of 7-13-year-old schoolchildren in southern Brazil.

Objective: The aim of the current study was to identify and describe the meal and snack patterns (breakfast, mid-morning snack, lunch, mid-afternoon snack, dinner and evening snack) of public schoolchildren.

Design: Cross-sectional study. Information on the previous day's food intake was obtained through the Web-CAAFE (Food Intake and Physical Activity of Schoolchildren), an interactive questionnaire, which divides daily food consumption into three meals (breakfast, lunch and dinner) and three snacks (mid-morning, mid-afternoon and evening).
