Community food environment and childhood obesity in a medium-sized Brazilian city: An approach to school and neighborhood environments.

OBJECTIVE: We aimed to analyze the relationship of community food environments with childhood obesity in a medium-sized Brazilian city. METHODS: This is a cross-sectional study with 366 schoolchildren aged 8 and 9 years. Children's body mass index (BMI), waist circumference and concentrations of total cholesterol (TC), high cholesterol density lipoprotein (HDL-c), low cholesterol density lipoprotein (LDL-c) and triglycerides (TG) were measured. The parent's nutritional status was assessed by calculating the BMI. All food stores within a 200- and 400-m radius buffers of schools and households were evaluated. The food stores were classified as healthy, unhealthy, and mixed according to the predominance of foods commercialized. Binary logistic regression models were proposed for each category. RESULTS: Over seventy percent (70.2%) of the food stores were categorized as "unhealthy". The prevalence of obesity was 15.6%. In the 200-m buffer around schools, there was an inverse and direct association between obesity and the presence of healthy food stores and unhealthy food stores, respectively. Around the households, there was an inverse association between the presence of healthy food stores and obesity in both buffers. CONCLUSION: The community food environment may be protective or potentiating childhood obesity, depending on the access and types of food sold.

Availability of food stores around Brazilian schools.

The aim of this study was to analyze the availability of food stores in the territory of schools. Ecological study conducted in Viçosa, Minas Gerais, Brazil, with all schools (N=42) and food stores (N=656). Data were collected through the objective evaluation of the environment, and the stores were categorized into healthy, unhealthy, mixed and supermarkets. Bivariate Ripley´s K function assessed the existence of clustering of categories of stores in the territory of schools. All the schools had at least one food store in their territory. Unhealthy stores were the most common and closest to the schools. There were more stores around private schools, offering high school education, located in the central region and in the highest per capita income tercile. The bivariate Ripley´s K function showed evidence of clustering of stores at all analyzed distances (400 to 1.5 km) with up to 3 times more establishments than would be expected if they were randomly distributed. Therefore, schoolchildren were likely exposed to unhealthy food environments, regardless of neighborhood income and location, which may contribute to inadequate food choices.

Resumo O objetivo deste estudo foi analisar a disponibilidade de estabelecimentos de venda de alimentos no território das escolas. Estudo ecológico conduzido em Viçosa, Minas Gerais, Brasil, com todas as escolas (N=42) e estabelecimentos de venda de alimentos (N=656). Dados foram coletados através de avaliação objetiva do ambiente, e estabelecimentos foram categorizados em saudáveis, não saudáveis, mistos e supermercados. Função K de Ripley bivariada avaliou a existência de agrupamento das categorias de estabelecimentos no território das escolas. Todas as escolas tinham no mínimo um estabelecimento de venda de alimentos em seu território. Estabelecimentos não saudáveis foram mais frequentes e próximos das escolas. Havia mais estabelecimentos no entorno de escolas particulares com ensino médio, localizadas na região central e de maior tercil de renda per capita. A função K de Ripley bivariada evidenciou o agrupamento de estabelecimentos em todas as distâncias analisadas (400 a 1,5 km), com três vezes mais estabelecimentos do que o esperado em uma distribuição aleatória. Portanto, escolares provavelmente estavam expostos a um ambiente alimentar não saudável, independentemente da renda da vizinhança e da localização das escolas, o que pode contribuir para escolhas alimentares inadequadas.

[Characteristics of the community food environment and home surroundings of households beneficiaries of the "Bolsa Família" (family aid) program]. / Características do ambiente alimentar comunitário e do entorno das residências das famílias beneficiárias do Programa Bolsa Família.

Knowing the food environment to which the households benefiting from the Bolsa Familia Program (PBF) are exposed is necessary to identify exposure to environments that favor worse food choices. This work aimed to characterize the community food environment of the urban area of the municipality of Ouro Preto (MG), Brazil, and the surroundings of the homes of households that are beneficiaries of the PBF. This ecological study was conducted with data from the Single Registry and the State Treasury Department Systems, both from 2014, and from the 2010 Census. Spatial analyses were conducted to evaluate the clusters of beneficiary households and establishments. The peripheral and with lower per capita income census tracts (CTs) had little or no establishment for food sales, and greater agglomeration of PBF beneficiary households closer to unhealthy establishments (median: 65.73 meters). There was a higher concentration of - mainly unhealthy - food sales establishments in the central CTs and higher per capita income (59.2%). Given the above, it becomes important to dialogue with other nutrition-related public policies to reduce inequalities and improve physical access to healthy food sales establishments.

Conhecer o ambiente alimentar a que as famílias beneficiárias do Programa Bolsa Família (PBF) estão expostas é necessário para identificar a exposição a ambientes que favoreçam piores escolhas alimentares. O objetivo deste trabalho foi caracterizar o ambiente alimentar comunitário da zona urbana do município de Ouro Preto e do entorno das residências das famílias beneficiárias do PBF. Trata-se de um estudo ecológico, conduzido com dados do Sistema de Cadastro Único e da Secretaria Estadual da Fazenda, ambos de 2014, e do Censo 2010. Foram realizadas análises espaciais para avaliar as aglomerações de famílias beneficiárias e de estabelecimentos. Os setores censitários (SC) periféricos e com menor renda per capita apresentaram pouco ou nenhum local de venda de alimentos, bem como maior aglomeração de famílias beneficiárias do PBF, que estão mais próximas a estabelecimentos considerados não saudáveis (mediana: 65,73 metros). Verificou-se maior concentração de locais de venda de alimentos, sobretudo não saudáveis, nos SC de localização central e de maior renda per capita (59,2%). Nesse caso, torna-se relevante o diálogo com outras políticas públicas interrelacionadas com a nutrição, visando reduzir as iniquidades e contribuir para melhorar o acesso físico a estabelecimentos de venda de alimentos saudáveis.

Fruit and vegetable consumption among older adults: influence of urban food environment in a medium-sized Brazilian city.

OBJECTIVE: To examine the association between urban food environment and regular consumption of fruits and vegetables (FV) by older adults from a medium-sized Brazilian city. DESIGN: Cross-sectional study based on data related to (1) objective assessment of establishments with predominant sale of unprocessed/minimally processed foods, mixed establishments and establishments with predominant sale of ultra-processed foods; (2) regular consumption of FV (≥ 5 times/week), health and socio-demographic variables of community-dwelling older adults. Tertiles of proximity between food establishments and older adults' residence were calculated. Poisson generalised estimating equations with robust variance, adjusted for individual and contextual variables, were used to estimate the independent association between the proximity of establishments and regular consumption of FV. SETTING: Medium-sized Brazilian city. SUBJECTS: Representative sample of community-dwelling older adults (n 549). RESULTS: Older adults travelled the longest distances to establishments with predominant sale of unprocessed/minimally processed foods. The longer the distance to establishments with predominant sale of unprocessed/minimally processed foods, the lower the prevalence of regular consumption of FV (tertile 2: prevalence ratio (PR) = 0·86; 95 % CI = 0·74, 0·99; tertile 3: PR = 0·84; 95 % CI = 0·72, 0·97). Older adults living larger distance tertiles from establishments with predominant sale of ultra-processed foods, mixed establishments or all categories of establishments had 16 % (PR = 0·84; 95 % CI = 0·73, 0·96), 19 % (PR = 0·81; 95 % CI = 0·71, 0·93) and 19 % (PR = 0·81; 95 % CI = 0·70, 0·94) lower prevalence of regular consumption of FV, respectively. CONCLUSION: The food environment is associated with regular consumption of FV among older adults. Longer distances from the residence of older adults to food establishments are independently associated with lower prevalence of regular consumption of FV.

Socioeconomic Disparities in the Community Food Environment of a Medium-Sized City of Brazil.

Objective: The purpose of this ecological study was to characterize the community food environment according to the socioeconomic condition of census tracts (CTs) in the urban area of a medium-sized city of southeastern Brazil in 2016.Method: Food establishments were identified on the streets covered by raters and information about type was collected through objective assessment. Geocoding was carried out from address observed by raters. Food establishments were categorized into establishments with predominant sale of natural or minimally processed foods, mixed establishments, and establishments with predominant sale of ultra-processed foods. The distribution of the number of establishments, by category, was evaluated according to tertiles of per capita income of the CT. The kernel estimation was used to analyze the density of establishments by category. The spatial pattern of the categories of establishments was investigated using the univariate Ripley's K-function.Results: A total of 656 establishments were evaluated. In all, 11.1% had predominant sale of natural or minimally processed foods, 44.5% were mixed, and 44.4% had predominant sale of ultra-processed foods. The average of establishments with predominant sale of natural or minimally processed foods, of ultra-processed foods, and all categories increased according to the income of the CT. There was a clustering of all categories of establishments in high-income CTs downtown. However, peripheral and low-income CTs were composed of a higher number of mixed establishments or those with predominant sale of ultra-processed foods than establishments with predominant sale of natural or minimally processed foods.Conclusions: On average, the number of all categories of establishments increased according to the per capita income of the CT and were clustered in central and higher-income regions of the city. These findings may have practical implications for the development of public policies to increase the availability of healthy foods and to reduce the sale of unhealthy foods.

Prevalence and factors associated with tea consumption in the first month of life in a birth cohort in the Northeast Region of Brazil / Prevalência e fatores associados ao uso de chá no primeiro mês de vida em uma coorte de nascimento na Região Nordeste do Brasil

Abstract Objectives: to determine the prevalence and analyze the factors associated with newborns drinking tea in a birth cohort. Methods: A cross-sectional study with nested prospective cohort was conduct with 329 puerperal women and their newborns in Vitória da Conquista, Bahia. Sociodemographic and information about the newborn's diet and mothers/babies was obtained at a maternity and 30 days after birth, at home visits. The prevalence ratios (PR) and its respective confidence intervals (CI95%) were estimated with Poisson regression models according to the hierarchical conceptual model. Results: the prevalence of tea consumption up to 30 days of life was 34.6% (CI95%=29.7; 40.0%). The sociodemographic and maternal characteristics associated with the outcome were not having a partner (PR = 1.39; CI95%=1.03-1.88), more than eight years of schooling (PR=1.38; CI95%=1.03-1.84), lower income (PR=2.21; CI95%=1.31-3.73), primiparous (PR=1.48; CI95%=1.01-2.17) and does not have any experience with breastfeeding before (PR=2.25; CI95%=1.48-3.41). As for the child, there was a higher prevalence of tea consumption than among those who received artificial milk in the first month of life (PR= 2.10; CI95%=1.62-2.73). Conclusions: the offer of tea in the first month of life was high. Tea consumption was positively associated with sociodemographic, maternal and newborn feeding factors.

Resumo Objetivos: determinar a prevalência e analisar fatores associados ao uso de chá em recém-nascidos em uma coorte de nascimento. Métodos: estudo transversal aninhado a uma coorte prospectiva conduzida em 329 puérperas e recém-nascidos em Vitória da Conquista, Bahia. Informações sociodemográficas, relativas à alimentação do recém-nascido e relacionadas aos pares mães-bebês foram obtidas na maternidade e aos 30 dias de nascimento, durante visita domiciliar. As razões de prevalência (RP) e seus respectivos intervalos de confiança (IC95%) foram estimados em modelos de regressão de Poisson conforme modelo conceitual hierárquico. Resultados: a prevalência do uso de chá até os 30 dias de vida foi de 34,6% (IC95%=29,7; 40,0%). As características sociodemográficas e maternas associadas ao desfecho foram não possuir companheiro (RP = 1,39; IC95%= 1,03-1,88), ter até oito anos de estudo (RP=1,38; IC95%= 1,03-1,84), menor renda (RP = 2,21; IC95%= 1,31-3,73), ser primípara (RP=1,48; IC95%= 1,01-2,17) e não possuir experiência anterior com amamentação (RP=2,25; IC95%= 1,48-3,41). Quanto à criança, houve maior prevalência de uso de chá entre as que receberam leite artificial no primeiro mês de vida (RP = 2,10; IC95%=1,62-2,73). Conclusões: a oferta do chá no primeiro mês de vida foi elevada. O uso do chá associou-se positivamente a fatores sociodemográficos, maternos e da alimentação do recém-nascido.

Factors associated with the length of hospital stay of women undergoing cesarean section.

OBJECTIVE: To evaluate whether age group, complications or comorbidities are associated with the length of hospitalization of women undergoing cesarean section. METHODS: A cross-sectional study was carried out between June 2012 and July 2017, with 64,437 women undergoing cesarean section and who did not acquire conditions during their hospital stay. Hospital discharge data were collected from national health institutions, using the Diagnosis-Related Groups system (DRG Brasil®). The DRG referring to cesarean section with additional complications or comorbidities (DRG 765) and cesarean section without complications or associated comorbidities (DRG 766) were included in the initial diagnosis. The influence of age group and comorbidities or complications present at admission on the length of hospital stay was assessed based on the means of the analysis of variance. The size of the effect was verified by Cohen's D, which allows evaluating clinical relevance. The criticality levels were identified using the Duncan test. RESULTS: The longest length of hospital stay was observed in the age group from 15 to 17 years old and among those aged 45 years old or more. The hospital stay of women with complications or comorbidities at the time of admission was also longer. Moreover, it was noted that the increase in criticality level was associated with an increase in the mean length of hospital stay. CONCLUSIONS: The length of hospital stay of women is higher among those belonging to the age group ranging from 15 to 17 years old and for those aged 45 years old or more. The presence of associated comorbidities, such as eclampsia, pre-existing hypertensive disorder with superimposed proteinuria and gestational hypertension (induced by pregnancy) with significant proteinuria increase the length of hospital stay. This study enabled the construction of distinct criticality level profiles based on the combination of age groups and the main comorbidities, which were directly related to the length of hospital stay.

Hospital-acquired conditions and length of stay in the pregnancy and puerperal cycle.

OBJECTIVE: To analyze the impact of the Hospital-Acquired Conditions (HAC) in women in the puerperal and pregnancy cycle during length of stay. METHODS: This cross-sectional study was conducted with 113,456 women, between July 2012 and July 2017, in Brazil's national hospitals of the supplementary healthcare networks and philanthropists accredited to the Unified Health System (SUS). Data on hospital discharges were collected using the Diagnosis-Related Groups (DRG Brasil®) system. All DRGs of the major diagnostic category 14 (MDC14), including pregnancy, childbirth and puerperium, were included. The impact of HAC on length of stay was estimated by Student's t-test, and the effect size by Cohen's d, which allows to assess clinical relevance. RESULTS: The most prevalent diagnostic categories related to MDC14 were vaginal and cesarean deliveries without complicating diagnoses, both at institutions accredited to SUS and those for supplementary health care. The prevalence of HAC was 3.8% in supplementary health and 2.5% in SUS. Hospitals providing services to supplementary health care providers had a longer length of stay considering HAC for patients classified as DRG: cesarean section with complications or comorbidities at admission (p < 0.001; Cohen's d = 0.74), cesarean section without complications or comorbidities at admission (p < 0.001, Cohen's d = 0.31), postpartum and post abortion without listed procedure (p < 0.001, Cohen's d = 1.05), and other antepartum diagnoses with medical complications (p < 0.001; Cohen's d = 0.77). CONCLUSIONS: This study showed that the prevalence of HAC was low both in the institutions accredited to attend by SUS and in those of supplementary health; however, its presence contributes to increasing the length of stay in cases of cesarean sections without complications or comorbidities in supplementary health institutions.

[Environmental factors associated with obesity in the adult population in a medium-sized Brazilian city]. / Fatores ambientais associados à obesidade em população adulta de um município brasileiro de médio porte.

The aim of this study was to estimate associations between environmental variables and obesity in the adult population in a medium-sized Brazilian city. This was a cross-sectional study with individual data from a population-based study and environmental data obtained by direct observation, later georeferenced by the addresses. The sample included 965 adults 20 to 59 years of age, and the study used anthropometric, socioeconomic, demographic, behavioral, and self-rated health data. The outcome variable was obesity, defined as body mass index (BMI) ≥ 30kg/m2. Retail food outlets were classified as: supermarkets and establishments with a predominance of healthy, unhealthy, and mixed foods. Settings for physical activity were categorized as public and private. Characterization of the social environment used the census tracts' per capita income in tertiles and the crime rate. Binary logistic regression analysis was performed according to the generalized estimating equations model. An inverse association was found between density of public and private locations for physical activity and obesity (OR = 0.95, 95%CI: 0.92-0.99; OR = 0.98, 95%CI: 0.97-0.99) in models adjusted by individual and environmental variables. In all the models, the highest per capita income tertile was inversely associated with obesity (p ≤ 0.05). The food environment and crime rates were not independently associated with obesity. These findings suggest that the census tract's income and its environment for physical activity can orient public policies to decrease obesity in this city.

O objetivo deste trabalho foi estimar as associações entre as variáveis ambientais e a obesidade em população adulta de um município brasileiro de médio porte. Trata-se de estudo transversal com dados individuais de estudo de base populacional e dados ambientais obtidos por meio de observação direta, posteriormente georreferenciados com base nos endereços. A amostra incluiu 965 adultos de 20 a 59 anos. Utilizaram-se dados antropométricos, socioeconômicos, demográficos, comportamentais e de percepção de saúde. A variável desfecho foi a obesidade, definida por índice de massa corporal (IMC) ≥ 30kg/m2. Os estabelecimentos de venda de alimentos foram classificados em: supermercados, estabelecimentos com predominância de alimentos saudáveis, não saudáveis e mistos. O ambiente para a prática de atividade física foi categorizado em público e privado. Para a caracterização do ambiente social utilizou-se a renda per capita do setor censitário em terços e taxa de criminalidade. Realizou-se análise de regressão logística binária pelo modelo de equações de estimativa generalizadas. Foi verificada associação inversa entre a densidade dos locais públicos e privados para a prática de atividade física e obesidade (OR = 0,95, IC95%: 0,92-0,99; OR = 0,98, IC95%: 0,97-0,99), em modelos ajustados por variáveis individuais e ambientais. Em todos os modelos o terço de renda per capita mais alto associou-se inversamente à obesidade (p ≤ 0,05). O ambiente alimentar e as taxas de criminalidade não foram independentemente associados à obesidade. Tais achados sugerem que a renda do setor censitário e o ambiente de atividade física podem direcionar políticas públicas para a diminuição da obesidade no município.

El objetivo de este estudio fue estimar las asociaciones entre las variables ambientales y la obesidad en una población adulta de un municipio brasileño de tamaño medio. Se trata de un estudio transversal, con datos individuales de un estudio de base poblacional, y datos ambientales obtenidos mediante la observación directa, posteriormente georreferenciados a partir de las direcciones. La muestra incluyó a 965 adultos de 20 a 59 años. Se utilizaron datos antropométricos, socioeconómicos, demográficos, comportamentales y de percepción de salud. La variable desenlace fue la obesidad, definida por índice de masa corporal (IMC) ≥ 30kg/m2. Los establecimientos de venta de alimentos se clasificaron en: supermercados, establecimientos con predominio de alimentos saludables, no saludables y mixtos. El ambiente para la práctica de actividad física se categorizó en público y privado. Para la caracterización del ambiente social se utilizó la renta per capita del censo en terciles y la tasa de criminalidad. Se realizó un análisis de regresión logística binaria por el modelo de ecuaciones de estimación generalizadas. Se verificó la asociación inversa entre la densidad de los lugares públicos y privados para la práctica de actividad física y obesidad (OR = 0,95, IC95%: 0,92-0,99; OR = 0,98, IC95%: 0,97-0,99), en modelos ajustados por variables individuales y ambientales. En todos los modelos el tercio de renta per capita más alto se asoció inversamente a la obesidad (p ≤ 0,05). El ambiente alimentario y las tasas de criminalidad no estuvieron asociados independientemente a la obesidad. Tales resultados sugieren que la renta procedente del censo y el ambiente de actividad física pueden dirigir políticas públicas, con el fin de disminuir la obesidad en el municipio.

CONCLUSIONS This study showed that the prevalence of HAC was low both in the institutions accredited to attend by SUS and in those of supplementary health; however, its presence contributes to increasing the length of stay in cases of cesarean sections without complications or comorbidities in supplementary health institutions.

RESUMO OBJETIVO Analisar o impacto das condições hospitalares adquiridas em mulheres no ciclo gravídico puerperal no tempo de permanência. MÉTODOS Este estudo transversal foi conduzido com 113.456 mulheres, entre julho de 2012 e julho de 2017, em hospitais nacionais da rede suplementar de saúde e filantrópicos credenciados para atendimento pelo Sistema Único de Saúde (SUS). Os dados das altas hospitalares foram coletados utilizando o sistema Diagnosis-Related Groups (DRG Brasil®). Foram incluídos todos os DRG que compõem a grande categoria diagnóstica 14 (MDC14), abrangendo gestação, parto e puerpério. O impacto das condições hospitalares adquiridas no tempo de permanência foi estimado por meio do teste t de Student, e o tamanho do efeito pelo d de Cohen, que permite avaliar a relevância clínica. RESULTADOS As categorias diagnósticas relacionadas à MDC14 mais prevalentes foram partos vaginais sem diagnósticos complicadores e cesáreas, tanto nas instituições credenciadas para atendimento pelo SUS quanto nas de saúde suplementar. A prevalência de condições hospitalares adquiridas foi de 3,8% na saúde suplementar e 2,5% no SUS. Observou-se maior tempo de permanência nos hospitais que prestam serviços a operadoras da saúde suplementar do Brasil na presença de CHA para as pacientes categorizadas nos DRG: cesariana com complicações ou comorbidades presentes à admissão (p < 0,001; d de Cohen = 0,74), cesariana sem complicações ou comorbidades presentes à admissão (p < 0,001; d de Cohen = 0,31), doenças puerperais e pós-aborto sem cirurgia (p < 0,001; d de Cohen = 1,05) e outras doenças da gravidez com complicações clínicas (p < 0,001; d de Cohen = 0,77). CONCLUSÕES O presente estudo revelou que a prevalência de condições adquiridas foi baixa tanto nas instituições credenciadas para atendimento pelo SUS quanto nas de saúde suplementar; entretanto, sua presença contribui para o aumento do tempo de permanência hospitalar em casos de cesáreas sem complicações ou comorbidades nas instituições de saúde suplementar.

Factors associated with the length of hospital stay of women undergoing cesarean section / Fatores associados ao tempo de permanência hospitalar de mulheres submetidas à cesariana

ABSTRACT OBJECTIVE To evaluate whether age group, complications or comorbidities are associated with the length of hospitalization of women undergoing cesarean section. METHODS A cross-sectional study was carried out between June 2012 and July 2017, with 64,437 women undergoing cesarean section and who did not acquire conditions during their hospital stay. Hospital discharge data were collected from national health institutions, using the Diagnosis-Related Groups system (DRG Brasil®). The DRG referring to cesarean section with additional complications or comorbidities (DRG 765) and cesarean section without complications or associated comorbidities (DRG 766) were included in the initial diagnosis. The influence of age group and comorbidities or complications present at admission on the length of hospital stay was assessed based on the means of the analysis of variance. The size of the effect was verified by Cohen's D, which allows evaluating clinical relevance. The criticality levels were identified using the Duncan test. RESULTS The longest length of hospital stay was observed in the age group from 15 to 17 years old and among those aged 45 years old or more. The hospital stay of women with complications or comorbidities at the time of admission was also longer. Moreover, it was noted that the increase in criticality level was associated with an increase in the mean length of hospital stay. CONCLUSIONS The length of hospital stay of women is higher among those belonging to the age group ranging from 15 to 17 years old and for those aged 45 years old or more. The presence of associated comorbidities, such as eclampsia, pre-existing hypertensive disorder with superimposed proteinuria and gestational hypertension (induced by pregnancy) with significant proteinuria increase the length of hospital stay. This study enabled the construction of distinct criticality level profiles based on the combination of age groups and the main comorbidities, which were directly related to the length of hospital stay.

RESUMO OBJETIVO Avaliar se grupo etário, complicações ou comorbidades estão associados ao tempo de internação de mulheres submetidas à cesariana. MÉTODOS Estudo transversal realizado entre junho de 2012 e julho de 2017, com 64.437 mulheres submetidas à cesariana e que não apresentaram condições adquiridas durante o tempo de permanência hospitalar. Os dados foram coletados a partir da alta hospitalar nas instituições nacionais de saúde, utilizando o sistema Diagnosis-Related Groups [Grupos de Diagnósticos Relacionados] (DRG Brasil®). Foram incluídos os DRG referentes à cesariana com complicações ou comorbidades adicionais ao diagnóstico inicial (DRG 765) e cesariana sem complicações ou comorbidades associadas (DRG 766). A influência do grupo etário e comorbidades ou complicações presentes na admissão sobre o tempo de permanência hospitalar foi avaliada por meio da análise de variância. O tamanho do efeito foi verificado pelo d de Cohen, que permite avaliar a relevância clínica. Os níveis de criticidade foram identificados utilizando o teste de Duncan. RESULTADOS O maior tempo de permanência hospitalar foi observado nos grupos etários de 15 a 17 anos e 45 anos ou mais. Mulheres que apresentaram complicações ou comorbidades presentes à admissão também apresentaram maior tempo de permanência hospitalar. Quantos aos níveis de criticidade, notou-se que seu aumento estava associado ao aumento na média do tempo de permanência hospitalar. CONCLUSÕES O tempo de permanência hospitalar de mulheres é maior entre aquelas pertencentes aos grupos etários de 15 a 17 anos e 45 anos ou mais. A presença de comorbidades associadas, como a eclâmpsia, o distúrbio hipertensivo pré-existente com proteinúria superposta e a hipertensão gestacional (induzida pela gravidez) com proteinúria significativa aumentam o tempo de permanência hospitalar. Este estudo possibilitou a construção de perfis distintos de níveis de criticidade a partir da combinação de grupos etários e das principais comorbidades, os quais se apresentaram diretamente relacionados ao tempo de permanência hospitalar.

Fatores ambientais associados à obesidade em população adulta de um município brasileiro de médio porte / Environmental factors associated with obesity in the adult population in a medium-sized Brazilian city / Factores ambientales asociados a la obesidad en una población adulta de un municipio brasileño de tamaño medio

Resumo: O objetivo deste trabalho foi estimar as associações entre as variáveis ambientais e a obesidade em população adulta de um município brasileiro de médio porte. Trata-se de estudo transversal com dados individuais de estudo de base populacional e dados ambientais obtidos por meio de observação direta, posteriormente georreferenciados com base nos endereços. A amostra incluiu 965 adultos de 20 a 59 anos. Utilizaram-se dados antropométricos, socioeconômicos, demográficos, comportamentais e de percepção de saúde. A variável desfecho foi a obesidade, definida por índice de massa corporal (IMC) ≥ 30kg/m2. Os estabelecimentos de venda de alimentos foram classificados em: supermercados, estabelecimentos com predominância de alimentos saudáveis, não saudáveis e mistos. O ambiente para a prática de atividade física foi categorizado em público e privado. Para a caracterização do ambiente social utilizou-se a renda per capita do setor censitário em terços e taxa de criminalidade. Realizou-se análise de regressão logística binária pelo modelo de equações de estimativa generalizadas. Foi verificada associação inversa entre a densidade dos locais públicos e privados para a prática de atividade física e obesidade (OR = 0,95, IC95%: 0,92-0,99; OR = 0,98, IC95%: 0,97-0,99), em modelos ajustados por variáveis individuais e ambientais. Em todos os modelos o terço de renda per capita mais alto associou-se inversamente à obesidade (p ≤ 0,05). O ambiente alimentar e as taxas de criminalidade não foram independentemente associados à obesidade. Tais achados sugerem que a renda do setor censitário e o ambiente de atividade física podem direcionar políticas públicas para a diminuição da obesidade no município.

Abstract: The aim of this study was to estimate associations between environmental variables and obesity in the adult population in a medium-sized Brazilian city. This was a cross-sectional study with individual data from a population-based study and environmental data obtained by direct observation, later georeferenced by the addresses. The sample included 965 adults 20 to 59 years of age, and the study used anthropometric, socioeconomic, demographic, behavioral, and self-rated health data. The outcome variable was obesity, defined as body mass index (BMI) ≥ 30kg/m2. Retail food outlets were classified as: supermarkets and establishments with a predominance of healthy, unhealthy, and mixed foods. Settings for physical activity were categorized as public and private. Characterization of the social environment used the census tracts' per capita income in tertiles and the crime rate. Binary logistic regression analysis was performed according to the generalized estimating equations model. An inverse association was found between density of public and private locations for physical activity and obesity (OR = 0.95, 95%CI: 0.92-0.99; OR = 0.98, 95%CI: 0.97-0.99) in models adjusted by individual and environmental variables. In all the models, the highest per capita income tertile was inversely associated with obesity (p ≤ 0.05). The food environment and crime rates were not independently associated with obesity. These findings suggest that the census tract's income and its environment for physical activity can orient public policies to decrease obesity in this city.

Resumen: El objetivo de este estudio fue estimar las asociaciones entre las variables ambientales y la obesidad en una población adulta de un municipio brasileño de tamaño medio. Se trata de un estudio transversal, con datos individuales de un estudio de base poblacional, y datos ambientales obtenidos mediante la observación directa, posteriormente georreferenciados a partir de las direcciones. La muestra incluyó a 965 adultos de 20 a 59 años. Se utilizaron datos antropométricos, socioeconómicos, demográficos, comportamentales y de percepción de salud. La variable desenlace fue la obesidad, definida por índice de masa corporal (IMC) ≥ 30kg/m2. Los establecimientos de venta de alimentos se clasificaron en: supermercados, establecimientos con predominio de alimentos saludables, no saludables y mixtos. El ambiente para la práctica de actividad física se categorizó en público y privado. Para la caracterización del ambiente social se utilizó la renta per capita del censo en terciles y la tasa de criminalidad. Se realizó un análisis de regresión logística binaria por el modelo de ecuaciones de estimación generalizadas. Se verificó la asociación inversa entre la densidad de los lugares públicos y privados para la práctica de actividad física y obesidad (OR = 0,95, IC95%: 0,92-0,99; OR = 0,98, IC95%: 0,97-0,99), en modelos ajustados por variables individuales y ambientales. En todos los modelos el tercio de renta per capita más alto se asoció inversamente a la obesidad (p ≤ 0,05). El ambiente alimentario y las tasas de criminalidad no estuvieron asociados independientemente a la obesidad. Tales resultados sugieren que la renta procedente del censo y el ambiente de actividad física pueden dirigir políticas públicas, con el fin de disminuir la obesidad en el municipio.

PREVALENCE AND FACTORS ASSOCIATED WITH ANEMIA IN CHILDREN ENROLLED IN DAYCARE CENTERS: A HIERARCHICAL ANALYSIS. / PREVALÊNCIA E FATORES ASSOCIADOS À ANEMIA EM CRIANÇAS DE CRECHES: UMA ANÁLISE HIERARQUIZADA.

OBJECTIVE: To determine the prevalence and factors associated with anemia in children younger than five years old enrolled in public daycare centers in a city in southwestern Bahia, in the northeast of Brazil. METHODS: This was a cross-sectional study that included a sample of 677 children enrolled in public daycare centers in Vitória da Conquista, Bahia, Brazil. A portable hemoglobinometer was used to measure hemoglobin. The concentration of <11 g/dL was considered the cutoff point for a diagnosis of anemia. A questionnaire was applied to parents/guardians in order to collect socioeconomic data, maternal characteristics and information on the child's health and nutrition. Height and weight were measured to assess the child's nutritional status. Poisson regression with robust variance and hierarchical selection of variables was used to identify factors associated with anemia. RESULTS: The prevalence of anemia was 10.2% and was more frequent in children whose homes had no sanitary facilities (PR 3.36; 95%CI 1.40-8.03); in those who did not exclusively breastfeed (PR 1.80; 95%CI 1.12-2.91); in children aged less than 36 months (PR 1.85; 95%CI 1.19-2.89) and those who had low height for age (PR 2.06; 95%CI 1.10-3.85). CONCLUSIONS: The prevalence of anemia is considered to be a mild public health problem in the children, who are enrolled in daycare centers. Children with inadequate sanitary conditions, and that were not exclusively breastfed, as well as younger children and children with a nutritional deficit, were more likely to present the condition.

OBJETIVO: Determinar a prevalência e os fatores associados à anemia em crianças menores de cinco anos assistidas em creches públicas de um município no sudoeste da Bahia. MÉTODOS: Estudo transversal com uma amostra de 677 crianças matriculadas nas creches públicas de Vitória da Conquista, Bahia. Para determinação da hemoglobina por meio de punção digital, utilizou-se hemoglobinômetro portátil, considerando-se valores de hemoglobina <11 g/dL como ponto de corte para o diagnóstico da anemia. Aplicou-se questionário aos pais ou responsáveis para coleta de informações socioeconômicas, características maternas e de saúde e nutrição da criança. Medidas antropométricas de peso e estatura foram utilizadas para avaliação do estado nutricional da criança. Análise de regressão de Poisson com variância robusta e seleção hierárquica das variáveis foi usada para verificar fatores associados com anemia. RESULTADOS: A prevalência de anemia foi de 10,2% e houve mais prevalência nas crianças cujas moradias não apresentavam instalação sanitária (RP 3,36; IC95% 1,40-8,03); naquelas que não receberam aleitamento materno exclusivo (RP 1,80; IC95% 1,12-2,91); nas crianças com idade inferior a 36 meses (RP 1,85; IC95% 1,19-2,89) e com baixa estatura para a idade (RP 2,06; IC95% 1,10-3,85). CONCLUSÕES: A prevalência de anemia pode ser considerada um problema de Saúde Pública menor em crianças de creches populares nesse município. Crianças com condições sanitárias inadequadas, que não receberam leite materno exclusivo, bem como as em idades mais precoces e com déficit nutricional foram mais suscetíveis.

Excess weight and factors associated in preschool of southwest of Bahia / Excesso de peso e fatores associados em pré-escolares do sudoeste da Bahia

Abstract Objectives: this study aimed to evaluate the environmental factors associated with excess weight in preschool children. Methods: a cross-sectional study involving 664 full-time preschoolers enrolled in public childcare centers in Vitória da Conquista (BA). The excess weight status has been defined according to the BMI/Age index and score Z above +2. The independent variables were grouped into maternal characteristics, socioeconomic, related to children and child care. We conducted multiple logistic regression to assess the association between excess weight and the variables studied. Results: a prevalence of excess weight was 5.7 %; 3.9% were overweight and 1.8% were obese. The factors associated with excess weight in children were cesarean delivery (OR: 2.59; IC95%: 1.11; 6.01); being singletons (OR: 3.32; IC95%: 1.44; 7.67); and exclusive breastfeeding of less than 4 months (OR: 2.59; IC95%: 1.12; 5.99). Conclusions: the results show that interventions to reduce and/or prevent excess weight should begin prenatally, with promotion of exclusive breastfeeding and natural birth, as well as nutritional advice for mothers with singletons.

Resumo Objetivos: avaliar a prevalência e os fatores associados ao excesso de peso em pré-esco-lares do sudoeste da Bahia. Métodos: estudo transversal envolvendo 664 pré-escolares matriculados em período inte-gral em creches públicas de Vitória da Conquista (BA). O excesso de peso foi definido considerando o índice IMC/idade maior que + 2 escore Z. As variáveis independentes foram agrupadas em características maternas, socioeconômica, relacionadas a criança e a creche. Realizou-se regressão logística múltipla para verificar a associação entre excesso de peso e as variáveis estudadas. Resultados: a prevalência de excesso de peso foi de 5,7%, sendo 3,9% de sobrepeso e 1,8% de obesidade. Os fatores associados ao excesso de peso infantil foram o parto cesáreo (Odds Ratio - OR: 2,59; Intervalo de Confiança - IC95%: 1,11; 6,01), ser filho único (OR: 3,32; IC95%: 1,44; 7,67) e aleitamento materno exclusivo inferior a 4 meses (OR: 2,59; IC95%: 1,12; 5,99). Conclusões: os resultados mostram que intervenções para redução e/ou prevenção do excesso de peso devem começar no pré-natal com incentivo ao aleitamento materno exclu-sivo e ao parto vaginal, além de orientações nutricionais para mães com apenas um filho.

Prevalence and factors associated to vitamin A deficiency in children attending public day care centers in the Southwest of Bahia / Prevalência e fatores associados com deficiência de vitamina A em crianças atendidas em creches públicas do Sudoeste da Bahia

Abstract Objectives: to determine the prevalence of vitamin A deficiency and factors associated to children attending public day care centers in the Southwest of Bahia. Methods: a cross-sectional study involving 303 children aged 24 to 60 months attending public day care centers in the city of Vitória da Conquista, BA. A questionnaire was applied for the parents or legal guardians to answer and the children's height and weight were measured. Blood samples were collected to analyze serum retinol taking in consideration the values below 0.70 imol/L as inadequate. The vaccination card was verified in relation to the adequacy of vitamin A supplementation. Food weighting was done to evaluate the consuming of lipids and vitamin A. The association between the variables and vitamin A deficiency was verified by logistic regression. Results: the prevalence of inadequate serum retinol levels was 13.1% (1.99 ± 1.17 imol/L); 4.3% were low height and 1.2% of thinness. Most children (91.7%) had their vitamin A doses outdated on their vaccination cards. The variables associated to vitamin A deficiency were children aged less or equal to 34 months (OR: 2.66, 95% CI: 1.23 - 5.74) and maternal age was less than 26 years (OR: 2.39; 95% CI: 1.11 - 5.17). Conclusions: vitamin A deficiency configures as a moderate public health problem in children attending public day care centers in the Southwest of Bahia.

Resumo Objetivos: determinar a prevalência de deficiência de vitamina A e os fatores associados em crianças assistidas em creches do Sudoeste da Bahia. Métodos: estudo transversal envolvendo 303 crianças de 24 a 60 meses assistidas em creches públicas de Vitória da Conquista - BA. Aplicado questionário com pais ou responsáveis e aferidas medidas de peso e estatura das crianças. Amostras de sangue coletadas para análise do retinol sérico, considerando níveis inadequados inferiores a 0,70 imol/L. O cartão de vacina foi verificado em relação à adequação da suplementação de vitamina A. Realizou-se pesagem direta dos alimentos para avaliação do consumo de lipídio e vitamina A. Associação entre as variáveis estudadas e a deficiência de vitamina A foi verificada por meio de regressão logística. Resultados: prevalência de níveis inadequados de retinol de 13,1% (1,99 ± 1,17 fimol/L); 4,3% baixa estatura e 1,2% magreza. A maioria das crianças (91,7%) estava com as doses de suplementação de vitamina A desatualizadas. As variáveis associadas com deficiência de vitamina A foram a idade da criança inferior ou igual a 34 meses (OR: 2,66; IC95%: 1,23 - 5,74) e idade materna inferior a 26 anos (OR: 2,39; IC95%: 1,11 - 5,17). Conclusões: a deficiência de vitamina A configura-se como um moderado problema da saúde pública em crianças assistidas em creches públicas do sudoeste baiano.
