Trends in the prevalence of obesity, overweight, and thinness among schoolchildren aged 7-14 years from southern Brazil (2002-2019).

OBJECTIVE: To analyze the obesity, overweight, and thinness trends among Brazilian schoolchildren by sex, age group, and type of school according to World Health Organization (WHO) and International Obesity Task Force (IOTF) criteria. METHODS: We conducted four surveys between 2002 and 2018/19 involving schoolchildren aged 7-14 years from a state capital in southern Brazil. Weight status was classified using both WHO and IOTF criteria. RESULTS: In the total sample, obesity prevalence based on the IOTF and the WHO criteria were 72% and 44% higher in 2018/19 compared with 2002, respectively. Over the whole period, the obesity prevalence increased among children (WHO: 10.1% vs. 14.1%; IOTF: 5.0% vs. 8.3%), and those from public schools (WHO: 10.5% vs. 16.4%; IOTF: 5.6% vs. 10.1%). There was no significant reduction in thinness prevalence over the analyzed period. CONCLUSION: Obesity prevalence remains on an upward trend in a state capital in southern Brazil, especially among children from public schools. A higher prevalence of overweight and obesity was observed using the WHO criteria compared with IOTF criteria.

Neighborhood Availability and Use of Food, Physical Activity, and Social Services Facilities in Relation to Overweight and Obesity in Children and Adolescents.

OBJECTIVE: To evaluate the association of a combined measure of availability and use of facilities from the food environment and overweight (including obesity) among schoolchildren, while taking into account the physical activity and social-assistance environments. METHODS: Cross-sectional study with a probabilistic sample of schoolchildren aged 7 to 14 years living in a southern Brazilian city (n = 2026). Multilevel analyses were performed with overweight as outcome and the food environment as main exposure. Models were adjusted for the physical activity and social-assistance environments, as well as individual and other residential neighborhood characteristics. RESULTS: Greater availability of restaurants around the home was associated with higher odds of overweight (odds ratio [OR] = 1.40; 95% CI = 1.06-1.85). Stronger associations were found for schoolchildren reporting to use restaurants (OR = 1.48; 95% CI = 1.15-1.90). This association remained significant after adjusting for the presence of other food retailers. Schoolchildren who had social-assistance facilities around their homes, but reported not to use them, showed consistently higher odds of being overweight (OR = 1.34; 95% CI = 1.01-1.78) as compared to schoolchildren who had these facilities near home and used them. The physical activity environment was not associated with the outcome. CONCLUSIONS: Availability and use of the food and social-assistance environments were significantly associated with overweight (including obesity) among the schoolchildren. Future research should consider the use of environmental facilities in combination to their geographical availability. Our results highlight the need for policies that limit the access to obesogenic food outlets by children and adolescents.

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 physical activity from the previous day were self-reported using the validated Web-CAAFE questionnaire. Adolescents completed a specific questionnaire about physical activity, meal consumption, and weight control behaviors. Parents/guardians responded to a sociodemographic and habits questionnaire. RESULTS: A total of 1671 schoolchildren participated in the study (response rate: 27.2%). About 63% of schoolchildren were enrolled in public schools. Most studied in the morning shift (54.2%), were female (53.1%) and aged between seven and 10 years (58.1%). The prevalence of overweight was 33.7% and obesity was 11.3%. CONCLUSIONS: The data obtained will allow us to assess the trend in the prevalence of overweight and obesity and associated factors when compared to other surveys performed. Descriptions of the logistics and protocols can help in the development and improvement of similar studies. It is hoped that the results of EPOCA 2018/2019 may help in the design of obesity prevention policies and programs for this population.

Presença de desertos alimentares em um distrito sanitário de uma capital brasileira: um estudo descritivo e exploratório sobre a distribuição espacial de estabelecimentos comerciais de alimentos / Food deserts in a health district of a Brazilian capital: a descriptive and exploratory study on the spatial distribution of commercial food establishments

Introdução: O ambiente alimentar que a comunidade está inserida pode influenciar, positiva ou negativamente no acesso à alimentação de qualidade e consequentemente na sua saúde. Objetivo: Identificar a presença de desertos alimentares em um distrito sanitário de uma capital brasileira. Métodos: Estudo descritivo, transversal e exploratório, utilizando dados secundários de diferentes fontes institucionais para mapear a distribuição espacial de estabelecimentos de comercialização de alimentos: restaurantes, padarias, supermercados, minimercados/mercearias, hortifrutigranjeiros, vendedores ambulantes e lanchonetes/fastfood. Os estabelecimentos foram agrupados nas categorias in natura, ultraprocessados e mistos, de acordo com a predominância do tipo de alimentos comercializados. Para a análise, a densidade de estabelecimentos in natura juntamente com os mistos por mil habitantes (usuários cadastrados nos centros de saúde) foram calculadas.  Resultados: Foram investigados 111 estabelecimentos, sendo 20% que comercializavam alimentos in natura (saudáveis), 27% alimentos ultraprocessados (não saudáveis) e 53% considerados mistos. Conclusões: Foram observadas áreas que podem ser consideradas desertos alimentares, locais onde há pouca (ou ausência) de oferta de alimentos in natura, e por consequência dificultando o acesso a alimentos saudáveis.

Introduction: The communities' food environment can positively or negatively influence access to quality food and consequently, people's health. Objective: Identify the presence of food deserts in a health district of a Brazilian capital. Methods: Descriptive, cross-sectional and exploratory study, using secondary data from different institutional sources to map the spatial distribution of food establishments such as restaurants, bakeries, supermarkets, minimarkets/grocery stores, fruit and vegetable stores, street vendors and cafeterias/fast food. The establishments were grouped into fresh, ultra-processed and mixed food categories, according to the predominance of the type of food offered. For the purpose of analysis, the density of fresh food establishments together with mixed food establishments per thousand inhabitants (as registered in the health centers) was calculated.  Results: A total of 111 establishments were investigated, 20% selling fresh foods (healthy), 27% ultra-processed foods (unhealthy) and 53% considered mixed food sellers. Conclusions: Areas that can be considered food deserts were found, i.e. places where there is little (or absence) of fresh food supply, and consequently making access to healthy foods difficult.

Association between healthy food environment and metabolic syndrome, waist circumference, and systolic blood pressure in older adults in Southern Brazil.

The aim of this study was to investigate the association between healthy food outlet proximity, metabolic syndrome (MS), and two of its components, waist circumference (WC) and systolic blood pressure (SBP), in older adults (63-107 years old, median age 73 years) living in Florianópolis, South Brazil in 2013-2014. This is a cross-sectional analysis of the second wave of the EpiFloripa Aging Cohort Study. Individual-level data on MS, WC, SBP, and socio-demographic and health-related characteristics were collected from face to face interviews. The healthy food environment was assessed via the number and types of establishments present. The residences of older adult participants were georeferenced using Geographical Information System (GIS) software. The number of each type of food establishment in a 500 m buffer around the each residence was determined. Multivariate linear regression was used to test association between food outlet proximity and continuous outcomes (SBP and WC), and multiple logistic regression was used to examine the relations between the predictor variables and the dichotomous outcome of MS (yes/no). The study revealed that greater frequency of supermarkets and restaurants in the neighborhood was associated with a lower likelihood of having MS. WC was lower in individuals living in places with greater availability of greengrocers' shops and restaurants. The results demonstrated that the number of establishments in a neighborhood is associated with cardiometabolic outcomes, and the likelihood of MS and increased WC is lower for older adults who live in neighborhoods with more access to establishments that sell foundational components of a healthy diet.

Autopercepção do tamanho corporal em escolares: um estudo transversal / Self-perception of body size in schoolchildren: a cross-sectional study

Introdução: A identificação precoce de imprecisões nas estimativas do tamanho corporal pode ser fundamental para planejar e realizar ações de prevenção e tratamento mais eficazes relacionadas à percepção e distúrbios da imagem corporal. Objetivo: Estimar a prevalência de superestimação e subestimação do tamanho corporal em escolares com magreza, peso normal e obesidade e os fatores associados. Métodos: Estudo transversal e de base escolar realizado em Florianópolis, Santa Catarina, Brasil. O estudo foi realizado com uma amostra de 1.530 escolares de sete a dez anos matriculados em escolas públicas e privadas de Florianópolis. Foram analisados dados sociodemográficos e antropométricos, bem como suas percepções sobre a imagem corporal. As percepções do tamanho corporal foram avaliadas utilizando-se as Escalas de Silhuetas para Crianças Brasileiras. Foi utilizada regressão logística para análise das associações. Resultados: A prevalência de magreza ou de peso normal em escolares que se consideravam com obesidade foi de 10%. Nenhum dos escolares com obesidade se consideraram magros ou com peso normal. Nos escolares magros, a imagem corporal desejada referente à obesidade manteve-se associada à percepção de considerar-se obeso (odds ratio = 2,64, p < 0,05). O sobrepeso, no sexo feminino, se manteve associado à condição de considerar-se magro (odds ratio = 3,07, p < 0,05). Conclusões: A superestimação e subestimação do tamanho corporal foram observadas entre crianças de 7 a 10 anos, particularmente do sexo feminino. Outros estudos utilizando diferentes variáveis e abordagens metodológicas são necessários para identificar, em profundidade, as causas da distorção da imagem corporal.

Introduction: Early identification of inaccuracies in body size estimations can be fundamental to plan and accomplish more effective prevention and treatment actions related to body image perception and disorders. Objective: To assess the prevalence of overestimation and underestimation of body size in thin, normal-weight, and obese schoolchildren and the factors associated. Methods: Cross-sectional and school-based study conducted in Florianópolis, Santa Catarina, Brazil. The study was conducted with a sample of 1,530 schoolchildren from seven to ten years old enrolled at public and private schools in Florianópolis-SC, Brazil. Sociodemographic and anthropometric data, as well as their perceptions on body image, were analyzed. Perceptions of body size were evaluated using the Figure Rating Scales for Brazilian Children. Logistic regression was used to analyze associations. Results: The prevalence of thinness or normal-weight schoolchildren who considered themselves with obesity was 10%. None of the schoolchildren with obesity considered themselves thin or normal-weighted. Considering thin and normal-weight schoolchildren, a desired body image equivalent to obesity was associated with an overestimation of their own obesity (odds ratio = 2.64, P < 0.05). Overweight in female schoolchildren was associated with an underestimation of self-thinness (odds ratio = 3.07, P < 0.05). Conclusions: Self-overestimation and underestimation of body sizes were observed among 7-10 year-old schoolchildren, particularly females. Further studies using different variables and methodological approaches are needed to know in depth the causes of distorted body image.

School feeding in Covid-19 times: mapping of public policy execution strategies by state administration / Alimentação escolar em tempos de Covid-19: mapeamento das estratégias de execução da política pública pelos gestores estaduais

Abstract Objective Identify and discuss strategies for execution the National School Feeding Program by state administrations during the coronavirus disease pandemic 2019. Methods This is a descriptive cross-sectional investigation. An exploratory review of the official publication of state governments and the Federal District to find out the strategies for the execution of the National School Feeding Program, after school closures due to the Covid-19 pandemic. Information on the form of execution and the public served by the action were reviewed in a descriptive manner. Results Out of the 27 federative units, 55% distributed food kits, 26% supplied food cards/vouchers and 19% provided food kits and food cards/vouchers. As to the scope, 37% maintained general service, 30% attended schoolchildren from families registered in the Brazilian cash transfer program (Bolsa Família) and 26% attended schoolchildren from families registered in the Underprivileged Families Registry. Conclusion The National School Feeding Program was weak in terms of assuring the Human Right to Adequate Food and Food and Nutrition Security. The slowness of the federal administration and the gaps in the regulations issued may explain the changes in the reported strategies, which, in their majority, violate the principle of universality.

RESUMO Objetivo Identificar e discutir estratégias de execução do Programa Nacional de Alimentação Escolar adotadas pelas gestões estaduais durante a pandemia de coronavírus 2019. Métodos Trata-se de pesquisa transversal descritiva. Foram realizadas visitas exploratórias nas páginas oficiais dos governos estaduais e do Distrito Federal para obtenção de informações a respeito das estratégias de execução do Programa Nacional de Alimentação Escolar após a suspensão das aulas pela pandemia por de COVID-19. As informações sobre a forma de execução e o público atendido pela ação foram analisadas de modo descritivo. Resultados Das 27 unidades federativas, 55% distribuíram kits de alimentos, 26% entregaram cartão/vale alimentação e 19% forneceram kits de alimentos e cartão/vale alimentação. Com relação à abrangência, 37% mantiveram atendimento universal, 30% atenderam escolares de famílias cadastradas no Programa Bolsa Família e 26% atenderam escolares de famílias registradas no Cadastro Único. Conclusão Verificou-se a fragilidade do Programa Nacional de Alimentação Escolar quanto à garantia do Direito Humano à Alimentação Adequada e da Segurança Alimentar e Nutricional. A morosidade do gestor federal e lacunas das normativas expedidas podem explicar as modificações nas estratégias relatadas e que, em sua maioria, ferem o princípio da universalidade.

Parental Perceived Travel Time to and Reported Use of Food Retailers in Association with School Children's Dietary Patterns.

Considering the association between the neighborhood food environment and individual eating behaviors, this study aimed to assess the association between parents' reported use of food facilities by their children, and parental perceived travel time to food facilities, with their children's dietary patterns. Parents reported the use of supermarkets, full-service and fast-food restaurants, and perceived travel time to these food retailers. To assess school children's food consumption, a previous day dietary recall was applied. Factor analysis was conducted to identify dietary patterns. To test the association between reported use and perceived travel time to food retailers and school children's dietary patterns, we performed multilevel linear regression analyses. Parents' reported use of supermarkets was associated with children's higher score in the "Morning/Evening Meal" pattern. The use of full-service and fast-food restaurants was associated with children's higher score in the "Fast Food" pattern. Higher parental perceived travel time to full-service and fast-food restaurants was associated with children's lower score in the "Fast Food" pattern. Although the use of full-service and fast-food restaurants was associated with a less healthy dietary pattern, the perception of living further away from these food retailers may pose a barrier for the use of these facilities.

Association between food, physical activity, and social assistance environments and the body mass index of schoolchildren from different socioeconomic strata.

The aim of this article was to evaluate associations between body mass index (BMI) and use of and distance from subjects homes of elements of the food and physical activity environments and use of social assistance environment, in schoolchildren from 7 to 14 years living in Florianópolis (South Brazil), stratified by monthly family income. A cross-sectional study was conducted with a probabilistic sample of 2152 schoolchildren. Univariate and multivariate linear regression analyses were conducted to test for associations between BMI and the use of and distance from supermarkets, bakeries and farmers' markets; use of and distance from parks/playgrounds and football pitches; and use of health centers, Reference Centers for Social Assistance, instructional facilities, residents associations, religious groups and a Brazilian program for cash transfer. Overweight and obesity rates were 21.5 and 12.7%, respectively. Among schoolchildren from low-income families, living more than 11 min' walk from parks/playgrounds was associated with higher BMI (ß = 0.53; 95% CI = 0.33-0.73). In the high-income strata, a longer distance from home to football pitches was associated with lower BMI (ß = -0.49; 95% CI = -0.69; -0.29). Neither food nor social assistance environments were associated with BMI of schoolchildren, even when analyzed by income strata.

Evidences of the association between individual attributes and bullying: a cross-sectional study with adolescents from Florianópolis, Santa Catarina State, Brazil.

This study aimed to estimate the prevalence of bullying and to verify the association between nutritional status, demographic and socioeconomic factors, and individual attributes among schoolchildren aged from 11 to 14 years. This is cross-sectional study with a probabilistic sample of 975 adolescents attending public and private schools in Florianópolis, Santa Catarina State, Brazil. Bullying was investigated with a self-administered questionnaire by applying Item Response Theory and dichotomized according to victimization or not. Body mass index (BMI) was classified according to the World Health Organization criteria. Data such as age, school type and location, household income, as well as the education background of the parents were collected by a questionnaire given to the parents. Crude and adjusted analyses were performed using logistic regression. The prevalence of victims of bullying and of overweight/obese adolescents was 13.2% and 29%, respectively. No association was found between bullying and age, sex, school type, mother's education, household income, and overweight/obesity. The crude analysis model indicated that overweight/obese adolescents and those with individual attributes (fat, thin, tall, short, good-looking, ugly, from a different ethnic background, rich, poor, with a disability and/or other) had a greater chance of being bullied. In the analysis model adjusted by household income and stratified by sex, boys were discriminated for being fat, good-looking, ugly, or for having a disability, while girls were discriminated for being fat, tall, short, ugly, rich, poor, among other individual attributes.

Body mass index and association with use of and distance from places for physical activity and active leisure among schoolchildren in Brazil. Cross-sectional study.

BACKGROUND: We evaluated associations between use of public places for physical activity and active leisure (PAAL) and their distances from subjects' homes and indicators of overweight and obesity, among schoolchildren from different socioeconomic levels, in the city of Florianópolis, Brazil. DESIGN AND SETTING: Cross-sectional study conducted on a sample of 2,152 schoolchildren aged 7 to 14 years, enrolled at 30 public and private schools. METHODS: The exposure variables were the use of public places for PAAL in the neighborhood and their distance from schoolchildren's homes. The outcomes were body mass index (BMI) and waist circumference (WC). Univariate and multivariate linear regression analyses were conducted according to income strata. RESULTS: Among the schoolchildren from low-income families, living closer to parks/playgrounds was associated with lower BMI (ß = -2.15; 95% confidence interval, CI = -2.53; -1.77) and lower WC (ß = -0.11 95% CI = -0.17; -0.05), while living at these distances from football pitches was associated with higher BMI (ß = 1.73; 95% CI = 0.31; 3.15) and larger WC measurements (ß = 0.03; 95% CI = 0.005; 0.14). Among the schoolchildren in low-income groups, living at an intermediate distance from beaches was associated with lower BMI (ß = -1.10; 95% CI = -1.61; -0.59). CONCLUSION: Living closer to parks/playgrounds was associated with lower BMI and WC among schoolchildren from low-income families. Living closer to football pitches was associated with higher BMI and WC among these schoolchildren. Living at intermediate distances from beaches was associated with lower BMI among these schoolchildren.

Utilization of food outlets and intake of minimally processed and ultra-processed foods among 7 to 14-year-old schoolchildren. A cross-sectional study

ABSTRACT BACKGROUND: Access to food retailers is an environmental determinant that influences what people consume. This study aimed to test the association between the use of food outlets and schoolchildren's intake of minimally processed and ultra-processed foods. DESIGN AND SETTING: This was a cross-sectional study conducted in public and private schools in Florianópolis, state of Santa Catarina, southern Brazil, from September 2012 to June 2013. METHODS: The sample consisted of randomly selected clusters of schoolchildren aged 7 to 14 years, who were attending 30 schools. Parents or guardians provided socioeconomic and demographic data and answered questions about use of food outlets. Dietary intake was surveyed using a dietary recall questionnaire based on the previous day's intake. The foods or food groups were classified according to the level of processing. Negative binomial regression was used for data analysis. RESULTS: We included 2,195 schoolchildren in the study. We found that buying foods from snack bars or fast-food outlets was associated with the intake frequency of ultra-processed foods among 11-14 years old in an adjusted model (incidence rate ratio, IRR: 1.11; 95% confidence interval, CI: 1.01;1.23). Use of butchers was associated with the intake frequency of unprocessed/minimally processed foods among children 11-14 years old in the crude model (IRR: 1.11; 95% CI: 1.01;1.22) and in the adjusted model (IRR: 1.11; 95% CI: 1.06;1.17). CONCLUSIONS: Use of butchers was associated with higher intake of unprocessed/minimally processed foods while use of snack bars or fast-food outlets may have a negative impact on schoolchildren's dietary habits.

Utilization and environmental availability of food outlets and overweight/obesity among schoolchildren in a city in the south of Brazil.

Among the causes of obesity, environmental factors have also been studied, in addition to genetic, social, psychological, and hormonal factors. The distribution of food outlets, facilitating or hindering food acquisition, can promote body weight control by encouraging healthier food habits. The objective of this study was to investigate associations between environmental availability and utilization of food outlets and overweight/obesity in 7 to 14-year-old schoolchildren in Florianópolis, in the South of Brazil. A logistic regression analysis identified a positive association between overweight/obesity in 2195 schoolchildren and the presence of restaurants in the vicinity of their homes (buffer = 400 meters). Being a member of a family that utilizes public markets/greengrocers was also positively associated with overweight/obesity in the sample investigated. Identifying the distribution of these establishments in the vicinity of the homes of schoolchildren in middle-income countries is an important element in understanding the role played by the food environment in weight gain in a variety of different settings.

Evidences of the association between individual attributes and bullying: a cross-sectional study with adolescents from Florianópolis, Santa Catarina State, Brazil / Evidências da associação entre atributos individuais e bullying: um estudo transversal em adolescentes de Florianópolis, Santa Catarina, Brasil / Evidencias de asociación entre atributos individuales y bullying: un estudio transversal con adolescentes de Florianópolis, Estado de Santa Catarina, Brasil

O estudo teve como objetivos estimar a prevalência de bullying e verificar a associação entre estado nutricional, fatores demográficos e socioeconômicos e atributos individuais em escolares entre 11 e 14 anos de idade. O estudo transversal usou uma amostra probabilística de 975 adolescentes matriculados em escolas públicas e privadas em Florianópolis, Santa Catarina, Brasil. O bullying foi investigado com um questionário auto-administrado, aplicando a Teoria da Resposta ao Item, e dicotomizado de acordo com a presença ou ausência de vitimização. O índice de massa corporal (IMC) foi classificado de acordo com os critérios da Organização Mundial da Saúde. Dados como idade, tipo e localização da escola, renda familiar e escolaridade dos pais foram coletados com um questionário entregue aos pais ou responsáveis. A regressão logística foi usada para as análises brutas e ajustadas. As taxas de prevalência de vitimização pelo bullying e de sobrepeso/obesidade foram 13,2% e 29%, respectivamente. Não houve associação entre bullying e idade, gênero, tipo de escola, escolaridade materna, renda familiar ou sobrepeso/obesidade. A análise não-ajustada indicou que os adolescentes com sobrepeso/obesidade e aqueles com determinados atributos individuais (gordo, magro, alto, baixo, bonito, feio, pertencente a outro grupo étnico, rico, pobre, portador de deficiência e/ou outros) tinham maior probabilidade de sofrerem bullying. Na análise ajustada para renda familiar e estratificada por gênero, os meninos eram discriminados por serem gordos, bonitos, feios, ou por serem portadores de deficiência, enquanto as meninas eram discriminadas por serem gordas, altas, baixas, feias, ricas ou pobres, entre outros atributos individuais.

El objetivo de este estudio fue estimar la prevalencia de bullying y verificar la asociación entre estatus nutricional, factores demográficos y socioeconómicos, así como atributos individuales, entre escolares con edades comprendidas entre los 11 a los 14 años. Este estudio transversal con una muestra probabilística de 975 adolescentes inscritos en escuelas públicas y privadas en Florianópolis, Estado de Santa Catarina, Brasil. El bullying se investigó mediante un cuestionario autoadministrado, a través de la aplicación de la teoría respuesta al ítem y con dicotomización, según la existencia de victimización o no. El índice de masa corporal (IMC) se clasificó según criterios de la Organización Mundial de la Salud. Se recogieron datos como: edad, tipo de escuela y ubicación, ingresos por hogar, así como formación educativa de los padres mediante un cuestionario entregado a los padres. Se realizaron análisis crudos y ajustados usando regresión logística. La prevalencia de víctimas de bullying y los adolescentes con sobrepeso/obesos fue de un 13,2% y un 29%, respectivamente. No se encontró asociación entre el bullying y la edad, sexo, tipo de escuela, educación de la madre, ingresos por hogar, y sobrepeso/obesidad. El modelo de análisis crudo de adolescentes con sobrepeso/obesos y aquellos con atributos individuales (gordo, flaco, alto, bajo, guapo, feo, procedente de un grupo étnico diferente, rico, pobre, con una discapacidad y/u otros) tenían mayores probabilidades de sufrir bullying. En el análisis del modelo ajustado por ingresos por hogar, y estratificado por sexo, los chicos fueron discriminados por ser gordos, guapos, feos, o por sufrir una discapacidad, mientras que las chicas lo fueron por ser gordas, altas, bajas, feas, ricas, pobres entre otros atributos individuales.

Geographic and socioeconomic distribution of food vendors: a case study of a municipality in the Southern Brazil.

The objective of this study was to identify the food vendor distribution profile of the city of Florianópolis, Santa Catarina State, Brazil, and investigate its association with the socioeconomic and demographic characteristics of different municipal regions. This descriptive, cross-sectional study obtained the location of food vendors from secondary data from different institutional sources. The density of different types of food vendors per 1,000 inhabitants in each municipal weighted area was calculated. The Kruskal-Wallis test compared the mean density of food vendors and the weighted income areas. The lowest-income regions had the lowest density of butchers, snack bars, supermarkets, bakeries/pastry shops, natural product stores, juice bars, and convenience stores. The identification of these areas may encourage the creation of public policies that facilitate healthy food startups and/or maintenance of healthy food vendors, especially in the lowest-income regions.

The identification of these areas may encourage the creation of public policies that facilitate healthy food startups and/or maintenance of healthy food vendors, especially in the lowest-income regions.

Resumo: Os objetivos desse estudo foram identificar o perfil de distribuição de comerciantes de alimentos no Município de Florianópolis, Santa Catarina, Brasil, e investigar a associação com as características das diferentes regiões do município. O estudo transversal, descritivo, obteve a localização dos comerciantes de alimentos a partir de dados secundários de diferentes fontes institucionais. Foi calculada a densidade dos diferentes tipos de comerciantes por mil habitantes em cada área ponderada do município. O teste de Kruskal-Wallis foi usado para comparar a densidade média de comerciantes de alimentos com as regiões do município, ponderadas por renda. As áreas de menor renda tiveram a menor densidade de açougueiros, lanchonetes, supermercados, padarias/pastelarias, lojas de produtos naturais, lojas de sucos e lojas de conveniência. A identificação dessas áreas pode incentivar a elaboração de políticas públicas que facilitem empreendimentos novos de comercialização de alimentos saudáveis e/ou a manutenção dos estabelecimentos de alimentos saudáveis, principalmente nas áreas de menor renda.

El estudio transversal, descriptivo, obtuvo la localización de los comerciantes de alimentos, a partir de datos secundarios de diferentes fuentes institucionales. Se calculó la densidad de los diferentes tipos de comerciantes por 1.000 habitantes en cada área ponderada del municipio. El test de Kruskal-Wallis se usó para comparar la densidad media de comerciantes de alimentos con las regiones del municipio, ponderadas por renda. Las áreas de menor renta tuvieron la menor densidad de carnicerías, bares de aperitivos, supermercados, panaderías/bocaterías, tiendas de productos naturales, tiendas de zumos y tiendas 24hrs. La identificación de esas áreas puede incentivar la elaboración de políticas públicas que faciliten emprendimientos nuevos de comercialización de alimentos saludables y/o el mantenimiento de los establecimientos de alimentos saludables, principalmente en las áreas de menor renta.

Aspects of the built environment associated with obesity in children and adolescents: A narrative review / Aspectos do ambiente construído associados à obesidade em crianças e adolescentes: revisão narrativa

OBJECTIVE: To perform a narrative literature review to describe the availability of food retailers (groceries and eateries) and their association with obesity in schoolchildren and adolescents. METHODS: The review included studies published from 2003 to 2013 listed in three databases with data on the child's school and/or home surroundings. RESULTS: There was a higher concentration of fast foods near the schools, especially high schools, public schools, or schools located in low-income regions. Moreover, children and adolescents living in areas further from convenience stores had better diets. CONCLUSION: Acknowledging the relationship between built environment and obesity by establishing scientific evidence is necessary for developing specific strategies that help to control the spread of obesity in this age group, aiming to construct healthier spaces. .

OBJETIVO: Realizar revisão narrativa da literatura, procurando descrever as características da disponibilidade de locais de comercialização de alimentos (pontos de venda de alimentos e pontos de alimentação) e sua associação com obesidade entre crianças em idade escolar e adolescentes. MÉTODOS: Foram identificados os estudos publicados entre 2003 e 2013 em três diferentes bases de dados que apresentaram resultados relacionados ao ambiente no entorno escolar e/ou residencial de crianças e adolescentes. RESULTADOS: No entorno das escolas, encontrou-se maior concentração de estabelecimentos do tipo fast food, em especial nas escolas de ensino médio, públicas ou localizadas em regiões de menor poder aquisitivo. Também foi identificado que crianças e adolescentes que residem em áreas mais distantes de lojas de conveniências apresentam dieta de melhor qualidade. CONCLUSÃO: O reconhecimento da relação entre ambiente construído e obesidade, por meio do estabelecimento de evidências científicas, é necessário para a elaboração de estratégias diferenciadas que contribuam para o controle do crescimento da obesidade nesse grupo etário, com um novo olhar para a construção de espaços mais saudáveis. .

[Retail food outlets and the association with overweight/obesity in schoolchildren from Florianópolis, Santa Catarina State, Brazil]. / Pontos de venda de alimentos e associação com sobrepeso/obesidade em escolares de Florianópolis, Santa Catarina, Brasil.

The study analyzes retail food outlets and their association with overweight/obesity in schoolchildren from Florianópolis, Santa Catarina State, Brazil. The study used a cross-sectional design with a random sample of 2,506 schoolchildren from public (n = 19) and private schools (n = 11). Overweight and obesity were classified according to World Health Organization guidelines for 2007, and crude and adjusted analyses were performed using Poisson regression. Prevalence of overweight/obesity was 34.2%. In public schools, 19.6% of the children were overweight and 13.5% were obese, as compared to 22.4% and 11.1% in private schools. An association was found in the public school system between overweight/obesity and the use of bakeries for food purchases (p = 0.004). In the private school system, children of families that bought groceries at the supermarket showed 26% less overweight/obesity compared to those who did not (p = 0.003). The data show an association between some types of food outlets (supermarkets and bakeries) and prevalence of overweight/obesity in the school-age population.
