Characteristics associated with dietary patterns in Brazilian children under two years of age

OBJECTIVE: To analyze the dietary patterns of Brazilian children under two years of age and assess their association with sociodemographic characteristics and health service use. METHODS: This is a cross-sectional study with data from the 2013 National Health Survey (PNS). Patterns were found for two age groups by principal component analysis and their correlation with characteristics of interest was tested by linear regression models. RESULTS: We found two dietary patterns for our groups. The first consisted of the consumption of fresh or minimally processed foods and the second, of ultra-processed foods. The greater adherence of children between six and 11 months to the first pattern was associated with higher per capita family income and urban residences in the most developed regions of Brazil. At 12 months or more, adherence related to white race/color, higher per capita family incomes, residence in more developed regions, and visits to private childcare. Adherence to the second pattern among children under one year of age was inversely associated with Yellow or Indigenous race/color, residence in the Brazilian Northeast, and childcare in specialized public or private services. At 12 months or more, greater adherence was directly associated with Black or Brown children who resided in more developed regions, and inversely associated with those living in the Brazilian Northeast. CONCLUSION: We found two opposite dietary patterns in Brazilian children under two years of age and that several social determinants modify their chance of adhering to these patterns.OBJETIVO: Analisar padrões alimentares de crianças brasileiras menores de dois anos e verificar a sua associação com características sociodemográficas e de utilização de serviços de saúde. MÉTODOS: Estudo transversal com dados da Pesquisa Nacional de Saúde (PNS) de 2013. A identificação dos padrões foi realizada em dois grupos etários por meio da análise fatorial por componentes principais e a correlação às características de interesse, testada por meio de modelos de regressão linear. RESULTADOS: Em ambos os grupos foram identificados dois padrões alimentares: o primeiro foi caracterizado pelo consumo de alimentos in natura ou minimamente processado e o segundo marcado somente pelo consumo de alimentos ultraprocessados. A maior adesão das crianças entre seis e 11 meses ao primeiro padrão foi associada à maior renda familiar per capita, residência em área urbana e nas regiões mais desenvolvidas do país. Com 12 meses ou mais, a adesão foi relacionada com a raça/cor branca, maior renda familiar per capita, residência nas regiões mais desenvolvidas e realizar consultas de puericultura em serviços privados. No segundo padrão, a aderência entre os menores de um ano foi inversamente associada com raça/cor amarela ou indígena, residência na região Nordeste e realização de puericultura nos serviços públicos especializados ou nos privados. A partir dos 12 meses, a adesão foi diretamente associada com raça/cor preta ou parda e residência nas regiões mais desenvolvidas, e inversamente associada com residência na região Nordeste. CONCLUSÃO: O estudo identificou dois padrões alimentares opostos em crianças brasileiras menores de dois anos, sendo que diferentes determinantes sociais modificam a chance de adesão a esses padrões

Mudanças no peso corporal na coorte NutriNet Brasil durante a pandemia de covid-19

Este estudo descreve modificações no peso corporal de participantes da coorte NutriNet Brasil (n = 14.259) ocorridas durante a pandemia de covid-19. Foram analisados dados informados em período anterior ao início da pandemia (26/01/2020 a 18/03/2020) e cerca de 6 meses após (14/09/2020 a 19/10/2020). O ganho de peso ≥ 2 kg alcançou 19,7% dos participantes, mostrando-se diretamente associado ao sexo masculino, à menor escolaridade e à presença prévia de excesso de peso, sendo inversamente associado à idade. A perda de peso ≥ 2kg alcançou 15,2% dos participantes, mostrando-se diretamente associada ao sexo masculino e à presença prévia de excesso de peso, sendo inversamente associada à idade.This study describes body weight changes among participants of the NutriNet Brasil cohort(n = 14,259) during the covid-19 pandemic.

Weight gain was directly associated withmale gender, lower education, and previous presence of overweight, and inversely associatedwith age. In turn, 15.2% lost ≥ 2kg, being directly associated with male gender and previouspresence of overweight and inversely associated with age

Disponibilidade domiciliar de alimentos no Brasil: distribuição e evolução (1974-2003)

OBJECTIVE: Data from household food budget surveys were examined in order to describe the regional and socio-economic distribution of household food availability in Brazil in 2002-2003 and trends from 1974 to 2003. METHODS: The study uses data from the "Pesquisa de Orçamento Familiar 2002-2003" budget survey conducted by the Brazilian Institute for Geography and Statistics (Instituto Brasileiro de Geografia e Estatística) from July 2002 to June 2003, including a national sample of 48,470 households. In each household, during seven consecutive days, all monetary and non-monetary expenses with food and beverages for family consumption were registered. Crude weights of purchased foods were transformed into calories and nutrients with the use of food composition tables. RESULTS: Adequate protein content and a high proportion of animal protein were found in all regions and income strata. These were the most important positive aspects identified in the household food availability in Brazil. On the other hand, all regions and socio-economic strata showed excess calories from sugar and little availability of fruits and vegetables. An excessive proportion of calories came from total and saturated fat in the more economically developed regions and in the urban milieu, as well as among higher-income families. Time-trends in metropolitan areas indicated a decline in the consumption of basic, traditional foods, such as rice and beans; notable increases (up to 400%) in the consumption of processed food items, such as cookies and soft drinks; maintenance of the excessive consumption of sugar; and a continuous increase in total fat and saturated fat content in the diet. CONCLUSIONS: Patterns and trends regarding household food availability in Brazil are consistent with the increasing participation of chronic non-communicable diseases in morbidity and mortality and with the continuous increase in the prevalence of obesity.OBJETIVO: Descrever a distribuição da disponibilidade domiciliar de alimentos no Brasil em 2002-2003 e avaliar sua evolução nas áreas metropolitanas do País no período 1974-2003. MÉTODOS: A principal base de dados do estudo é a Pesquisa de Orçamento Familiar de 2002-2003 realizada pelo Instituto Brasileiro de Geografia e Estatística em 48.470 domicílios brasileiros. Em cada domicílio, num período de sete dias consecutivos, foram registradas todas as aquisições, monetárias ou não monetárias, de alimentos e bebidas para consumo familiar. As quantidades de alimentos adquiridas foram transformadas em calorias e macronutrientes, usando tabelas de composição alimentar. RESULTADOS: Características positivas do padrão alimentar, encontradas em todas as regiões e em todas as classes de rendimento, foram a adequação do teor protéico das dietas e o elevado aporte relativo de proteínas de alto valor biológico. Características negativas, também disseminadas no País, foram excesso de açúcar e presença insuficiente de frutas e hortaliças na dieta. Nas regiões economicamente mais desenvolvidas, no meio urbano e entre famílias com maior rendimento houve também excesso de gorduras em geral e de gorduras saturadas. A evolução nas áreas metropolitanas do País evidenciou declínio no consumo de alimentos básicos, como arroz e feijão, aumentos de até 400% no consumo de produtos industrializados, como biscoitos e refrigerantes, persistência do consumo excessivo de açúcar e insuficiente de frutas e hortaliças e aumento no teor da dieta em gorduras em geral e gorduras saturadas. CONCLUSÕES: Padrões e tendências da disponibilidade domiciliar de alimentos no Brasil são consistentes com a importância crescente de doenças crônicas não transmissíveis no perfil de morbi-mortalidade e com o aumento contínuo da prevalência da obesidade no País

Consumo de hortaliças e sua relação com os alimentos ultraprocessados no Brasil

OBJETIVO: Caracterizar a aquisição domiciliar e o consumo alimentar individual de hortaliças no Brasil e analisar sua relação com o consumo de alimentos ultraprocessados. MÉTODOS: Foram utilizados dados de aquisição de alimentos para consumo no domicílio e de consumo alimentar individual da Pesquisa de Orçamentos Familiares 2008–2009. A Pesquisa de Orçamentos Familiares estudou a aquisição de alimentos de 55.970 domicílios e o consumo alimentar de 34.003 indivíduos com 10 anos ou mais de idade. Os alimentos de interesse neste estudo foram as hortaliças (excluindo raízes e tubérculos) e os alimentos ultraprocessados. A quantidade de hortaliças (gramas) adquiridas e consumidas foi descrita para o conjunto dos brasileiros e segundo quintos da participação calórica de alimentos ultraprocessados na alimentação. Para tanto, foram calculados os valores brutos e preditos, obtidos por modelos de regressão ajustados por variáveis sociodemográficas. Analisaram-se os tipos mais adquiridos de hortaliças (% na quantidade total) e, em relação ao consumo alimentar individual, a variedade de hortaliças consumidas (número absoluto), a participação (%) dos tipos de preparação culinária à base de hortaliças e os horários de consumo. RESULTADOS: A aquisição domiciliar média ajustada de hortaliças foi 42,9 g/per capita/dia. O consumo individual médio ajustado foi 46,1 g. Verificou-se relação inversa entre aquisição domiciliar e consumo individual de hortaliças e de alimentos ultraprocessados. Dez tipos de hortaliças respondem por mais de 80% da quantidade total habitualmente adquirida. A variedade consumida foi, em média, 1,08 tipo/per capita/dia. Cerca de 60% das hortaliças foram consumidas cruas, sendo a quantidade consumida no almoço duas vezes maior que aquela do jantar e indivíduos com maior consumo de alimentos ultraprocessados tenderam a consumir quantidade ainda menor de hortaliças no jantar. CONCLUSÕES: O consumo de hortaliças no Brasil é insuficiente, sendo pior entre indivíduos com maior consumo de alimentos ultraprocessados. O hábito mais frequente foi consumir hortaliças cruas, no almoço e com limitada variedade.OBJECTIVE: To characterize the household purchase and the individual consumption of vegetables in Brazil and to analyze their relation with the consumption of ultra-processed foods. METHODS: We have used data on the purchase of food for household consumption and individual consumption from the 2008–2009 Brazilian Household Budget Survey. The Brazilian Household Budget Survey studied the purchase of food of 55,970 households and the food consumption of 34,003 individuals aged 10 years and over. The foods of interest in this study were vegetables (excluding roots and tubers) and ultra-processed foods. We have described the amount of vegetables (grams) purchased and consumed by all Brazilians and according to the quintiles of caloric intake of ultra-processed food. To this end, we have calculated the crude and predicted values obtained by regression models adjusted for sociodemographic variables. We have analyzed the most commonly purchased types of vegetables (% in the total amount) and, in relation to individual food consumption, the variety of vegetables consumed (absolute number), the participation (%) of the types of culinary preparations based on vegetables, and the time of consumption. RESULTS: The adjusted mean household purchase of vegetables was 42.9 g/per capita/day. The adjusted mean individual consumption was 46.1 g. There was an inverse relation between household purchase and individual consumption of vegetables and ultra-processed foods. Ten types of vegetables account for more than 80% of the total amount usually purchased. The variety consumed was, on average, 1.08 type/per capita/day. Approximately 60% of the vegetables were eaten raw, and the amount consumed at lunch was twice that consumed at dinner; individuals with higher consumption of ultra-processed foods tended to consume even less vegetables at dinner. CONCLUSIONS: The consumption of vegetables in Brazil is insufficient, and this is worse among individuals with higher consumption of ultra-processed foods. The most frequent habit was to consume raw vegetables at lunch and with limited variety

Out-of-Home Food Consumers in Brazil: What Do They Eat?

Considering the increased contribution of foods consumed outside home and their potential impact on diet, this study aims to identify eating out patterns and their association with nutritional dietary quality in Brazil. We used the Individual Food Intake Survey 2008-2009, conducted with 34,003 individuals aged 10 and up. We used factor analysis by principal component to identify out-of-home eating patterns and linear regression to explore the association between patterns scores and dietary quality. We identified three food patterns. The Traditional meal pattern carried more rice, beans, meat, roots and tubers, pasta, vegetables and eggs. The typical Brazilian breakfast/tea pattern carried more fresh bread, margarine, milk, cheese and butter. The Ultra-processed food pattern carried more ready-to-eat meals and soft drinks. The traditional meal pattern was positively associated with calories from proteins, fiber, iron, potassium and sodium densities, whereas typical Brazilian breakfast/tea and ultra-processed food patterns were positively associated with energy density, the percentage of calories from lipids or carbohydrates, trans fat and free sugar. Out-of-home eating may have a negative impact on nutritional dietary quality when based on ultra-processed food. However, it is possible to maintain a healthy out-of-home diet with adherence to traditional Brazilian cuisine.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Nucleo Pesquisas Epidemiol Nutr & Saude NUPENS, BR-01246907 Sao Paulo, BrazilUniv Sao Paulo FMUSP, Fac Med, Dept Med Prevent, BR-01246903 Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Dept Polit Publ & Saude Colet, BR-11015020 Sao Paulo, BrazilUniv Fed Uberlandia, Fac Med, Curso Nutr, BR-38400902 Uberlandia, MG, BrazilInst Def Consumidor IDEC, BR-05002000 Sao Paulo, BrazilUniv Fed Sao Paulo UNIFESP, Dept Polit Publ & Saude Colet, BR-11015020 Sao Paulo, BrazilWeb of Scienc

Três décadas da disponibilidade domiciliar de alimentos segundo a NOVA – Brasil, 1987–2018

OBJECTIVE To evaluate the trend of household food acquisition according to the NOVA classification in Brazil between 1987–1988 and 2017–2018. METHODS We used household food acquisition data from five editions of the Pesquisas de Orçamentos Familiares (Household Budget Surveys), conducted by the Instituto Brasileiro de Geografia e Estatística (Brazilian Institute of Geography and Statistics), in the years 1987–1988, 1995–1996, 2002–2003, 2008–2009, and 2017–2018. All reported foods were categorized according to the NOVA classification. The household availability of food groups and subgroups was expressed through their share (%) in total calories, for all Brazilian families, by household situation (urban or rural), for each of the five geographic regions of the country, by fifths of the household income per capita distribution (2002–2003, 2008–2009 and 2017–2018 surveys), and for the 11 main urban regions of the country (1987–1988, 1995–1996, 2002–2003, 2008–2009 and 2017–2018 surveys). Linear regression models were used to assess the trend of increasing or decreasing food purchases. RESULTS The diet of the Brazilian population is still composed predominantly of foods in natura or minimally processed and processed culinary ingredients. However, our findings point to trends of increasing share of ultra-processed foods in the diet. This increase of 0.4 percentage points per year between 2002 and 2009 slowed down to 0.2 percentage points between 2008 and 2018. The consumption of ultra-processed food was higher among households with higher income, in the South and Southeast regions, in urban areas, and in metropolitan regions. CONCLUSION Our results indicate an increase in the share of ultra-processed foods in the diet of Brazilians. This is a worrisome scenario, since the consumption of such foods is associated with the development of diseases and the loss of nutritional quality of the diet.OBJETIVO Avaliar a tendência da aquisição domiciliar de alimentos de acordo com a classificação NOVA no Brasil entre 1987–1988 e 2017–2018. MÉTODOS Foram utilizados dados de aquisição domiciliar de alimentos provenientes de cinco edições da Pesquisas de Orçamentos Familiares, realizada pelo Instituto Brasileiro de Geografia e Estatística, nos anos 1987–1988, 1995–1996, 2002–2003, 2008–2009 e 2017–2018. Todos os alimentos reportados foram categorizados segundo a classificação NOVA. A disponibilidade domiciliar dos grupos e subgrupos de alimentos foi expressa por meio de sua participação (%) nas calorias totais, para o conjunto das famílias brasileiras, por situação do domicílio (urbana ou rural), para cada uma das cinco regiões geográficas do país, por quintos da distribuição de renda domiciliar per capita (inquéritos de 2002–2003, 2008–2009 e 2017–2018); e para as 11 principais regiões urbanas do país (inquéritos de 1987–1988, 1995–1996, 2002–2003, 2008–2009 e 2017–2018). Modelos de regressão linear foram utilizados para avaliar a tendência de aumento ou diminuição na aquisição dos alimentos. RESULTADOS A dieta da população brasileira ainda é composta predominantemente por alimentos in natura e minimamente processados e ingredientes culinários processados. No entanto, nossos achados apontam tendências de aumento da participação de alimentos ultraprocessados na dieta. Esse aumento que foi de 0,4 pontos percentuais ao ano na primeira porção do período estudado, entre 2002 e 2009, e desacelerou para 0,2 pontos percentuais entre 2008 e 2018. O consumo de alimentos ultraprocessados foi maior entres os domicílios de maior renda, nas regiões Sul e Sudeste, na área urbana, e nas regiões metropolitanas. CONCLUSÃO Os resultados do presente estudo apontam um aumento na participação de alimentos ultraprocessados na dieta dos brasileiros. Cenário preocupante, uma vez que o consumo de tais alimentos está associado ao desenvolvimento de doenças e à perda da qualidade nutricional da dieta

Food consumption and eating behavior among Brazilian adolescents: National Adolescent School-based Health Survey (PeNSE), 2009

O objetivo deste artigo é descrever características de consumo e comportamento alimentar de adolescentes brasileiros e sua associação com fatores sociodemográficos. Estudou-se, em 2009, amostra representativa de alunos do 9º ano do ensino fundamental de escolas públicas e privadas das 26 capitais brasileiras e do Distrito Federal. Utilizou-se questionário autoaplicável sobre atributos sociodemográficos, consumo e comportamento alimentar, entre outros. Estimativas dos indicadores construídos foram apresentadas para o total da população e por sexo. A associação de cada um dos indicadores com variáveis sociodemográficas foi examinada por meio de regressão logística. A maioria dos adolescentes consumia regularmente feijão (62,6%), leite (53,6%) e guloseimas (50,9%), realizava pelo menos o almoço ou o jantar com a mãe ou responsável (62,6%) e comia assistindo televisão ou estudando (50,9%). Em geral, as meninas estavam mais expostas a práticas alimentares não desejáveis, e o melhor nível socioeconômico associou-se a maiores prevalências dos indicadores estudados. Os resultados revelaram consumo regular dos marcadores de alimentação não saudável e consumo inferior ao recomendado dos de alimentação saudável, apontando a necessidade de ações de promoção de saúde dirigidas a jovens.The objective of this article is to describe the characteristics of food consumption and eating behavior of adolescents and its association with socio-demographic factors. In 2009, a random sample of students in 9th grade of elementary education at public and private schools from 26 Brazilian state capitals and Federal District was studied. It was applied a self-administered questionnaire with socio-demographic attributes, food consumption and eating behavior, among others. Estimates of the constructed indicators were presented for the total population and by sex. The association of each indicator with socio-demographic variables was examined by logistic regression. The results showed that over half of adolescents presented frequent consumption of beans (62.6%), milk (53.6%) and sweets (50.9%), and held at least lunch or dinner with the mother or responsible (62.6%) and watching television or studying (50.9%). In general, girls were more exposed to undesirable eating habits and higher socioeconomic status was associated with a higher prevalence of the indicators studied. The results revealed regular consumption of unhealthy diet markers and consumption of less than the recommended for a healthy diet, pointing the need for strengthening health promotion activities targeting young people

Ultra-processed food intake and diet carbon and water footprints: a national study in Brazil

OBJECTIVE: To study the association between ultra-processed food consumption and carbon and water footprints of the Brazilian diet. METHODS: Cross-sectional analysis on data collected in 2008-9 on a probabilistic sample of the Brazilian population aged ≥ 10 years (n = 32,886). Individual food intake was assessed using two food records. The environmental impact of individual diets was calculated by multiplying the amount of each food by coefficients that quantify the atmospheric emissions of greenhouse gases in grams of carbon dioxide equivalent (carbon footprint) and freshwater use in liters (water footprint), both per gram or milliliter of food. The two coefficients consider the food life cycle ‘from farm to fork.’ Crude and adjusted linear regression models and tests for linear trends assessed the association between the ultra-processed food contribution to total energy intake (quintiles) and the diet carbon and water footprints. Potential confounders included age, sex, education, income, and region. Total energy intake was assessed as a potential mediation variable. RESULTS: In the crude models, the dietary contribution of ultra-processed foods was linearly associated with the carbon and water footprints of the Brazilian diet. After adjustment for potential confounders, the association remained significant only regarding the diet water footprint, which increased by 10.1% between the lowest and highest quintile of the contribution of ultra-processed foods. Additional adjustment for total energy intake eliminated this association indicating that the dietary contribution of ultra-processed foods increases the diet water footprint by increasing energy intake. CONCLUSIONS: The negative impact of ultra-processed foods on the diet water footprint, shown for the first time in this study, adds to the negative impacts of these foods, already demonstrated regarding dietary nutrient profiles and the risk for several chronic non-communicable diseases. This reinforces the recommendation to avoid ultra-processed foods made in the official Brazilian Dietary Guidelines and increasingly in dietary guidelines of other countries
