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.

Food consumption and its association with leisure-time physical activity and active commuting in Brazilian workers.

Background/objectives: An in-depth understanding of the relationship between food consumption and physical activity is relevant since these behaviours could influence each other, while both have an effect on obesity and chronic diseases. In this context, the aim of this study was to investigate the effect of various combinations of food consumption (fruits, vegetables, sweets and snacks) on the associations with PA domains (leisure and commute) among Brazilian industrial workers.

Subjects/methods: This is part of a cross-sectional national survey developed in Brazil using data from the "Lifestyle and Leisure Habits of Industrial Workers" project.

Empirically derived dietary patterns through latent profile analysis among Brazilian children and adolescents from Southern Brazil, 2013-2015.

The aims of this study were to identify dietary patterns (DPs) of children and adolescents participating in three cross-sectional surveys (2013-2015) and to test their associations with sociodemographic variables, physical activity (PAS), screen-based sedentary activity (SA), and weight status. One-day data were obtained from 5,364 schoolchildren (7-12 years) from public schools of Florianopolis (South of Brazil), using the validated questionnaire Web-CAAFE (Food Intake and Physical Activity of Schoolchildren). DPs were derived from the frequency of daily consumption of 32 foods/beverages by latent profile analysis.

Individual characteristics and public or private schools predict the body mass index of Brazilian children: a multilevel analysis.

The aim of this study was to determine the contribution of individual and school characteristics to the variability in body mass index (BMI) z-scores of 7 to 10 years old children. Anthropometric and sociodemographic data from two cross-sectional studies conducted with schoolchildren from the 2nd to the 5th grades of elementary schools were analyses (n = 2,936 in 2002, and n = 1,232 in 2007). Multilevel modeling was used to estimate variations in BMI at child and school levels.

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.

Changes in total and central adiposity and body fat distribution among 7-10-year-old schoolchildren in Brazil.

Objective: To describe changes in total and central adiposity and body fat distribution in children over a 5-year period by investigating variations in BMI, waist circumference (WC), waist-to-height ratio (WHtR) and skinfold thicknesses (SFT).

Design: A school-based sample of children from 2nd to 5th grades of elementary schools participated in two cross-sectional studies in 2002 (n 2936) and 2007 (n 1232).

Setting: Public and private schools of Florianopolis, Brazil.

Performance of references based on body mass index for detecting excess body fatness in schoolchildren aged 7 to 10 years.

Objective: To compare the sensitivity and specificity of body mass index (BMI)-based classification systems and to determine the optimal cut-offs for predicting excess body fatness in schoolchildren.

Methods: 2795 schoolchildren aged 7 - 10 years were examined. Excess body fatness was defined as the standardized residuals of the sum of three skinfold thickness ranking at or above the 90th percentile.

Diagnostic accuracy of anthropometric indices in predicting excess body fat among seven to ten-year-old children.

Purpose: To evaluate the accuracy of the body mass index (BMI), waist circumference (WC) and waist-to-height ratio (WHtR) in detecting excess body fat among schoolchildren in Florianópolis, Santa Catarina.

Methods: Cross-sectional study with 2,772 schoolchildren aged seven to ten years. Receiver Operating Characteristic (ROC) curves were used to compare the diagnostic accuracy of the BMI, the WC and the WHtR in identifying children with excess body fat (defined as values that were equal to or higher than the 90th percentile of the standardized residuals obtained from the sum of the four skinfolds thickness).

Trends in adiposity in Brazilian 7-10-year-old schoolchildren: evidence for increasing overweight but not obesity between 2002 and 2007.

Background: The negative health consequences of childhood overweight/obesity (OW/OB) are well known. Therefore, an accurate monitoring of the OW/OB prevalence is essential. Anthropometry is the most practical and cost-effective method for nutritional status evaluation.

Clustering of risk factors for non communicable diseases in adults from Florianopolis, SC.

Objective: To investigate clustering patterns of health risk behaviors for non communicable diseases and its associated factors.

Methods: a Random telephone survey with 1,996 adults from Florianopolis, SC, was conducted in 2005. Tobacco use, high alcoholic intake episodes, fruit consumption and physical inactivity were investigated.

[Changes in food consumption and physical activity in schoolchildren of Florianópolis, Southern Brazil, 2002-2007].

Objective: To assess changes in food consumption and physical activity levels in schoolchildren.

Methods: A study was conducted with a representative sample (n = 4,168) of schoolchildren aged between seven and ten years living in the city of Florianópolis, Southern Brazil. Food consumption and physical activity were assessed in two school-based studies in 2002 (n = 2,936; 51% boys; mean age = 8.
