Abstract Background The EAT-Lancet diet is a diet aimed at promoting population and planetary health from the perspective of sustainable diets in terms of environmental and health aspects. This study aimed to assess the association between adherence to the EAT-Lancet diet and cardiometabolic risk factors among adults and elderly individuals in a capital city in the northeastern region of Brazil. Methods This is an analytical cross-sectional observational study from a population-based sample conducted between 2019 and 2020, involving 398 non-institutionalized adults and elderly people, of both sexes from “Brazilian Usual Consumption Assessment” study (Brazuca-Natal). There was a 38% response rate due to the suspension of data collection due to the covid-19 pandemic, but According to the comparative analysis of socioeconomic and demographic variables between the surveyed and non-surveyed sectors, losses were found to be random (p = 0.135, Little’s MCAR test). Socioeconomic and lifestyle data, anthropometric measurements, and dietary consumption were collected. We used the Planetary Health Diet Index (PHDI) and the Cardiovascular Health Diet Index (CHDI) for cardiovascular health to assess adherence to the diet’s sustainability. The evaluated cardiometabolic parameters included fasting blood glucose, triglycerides, total cholesterol, HDL-C, LDL-C, and systolic and diastolic blood pressure measurements. We also assessed the presence of type 2 diabetes mellitus, arterial hypertension, and dyslipidemia. For the data analyses, sample weights and the effect of the study design were taken into account. Pearson’s chi-square test was used to evaluate the statistical significance of frequencies. Multiple linear regression models assessed the associations between PHDI and CHDI and its components and the cardiometabolic parameters. Results The mean PHDI was 29.4 (95% CI 28.04:30.81), on a total score ranging from 0 to 150 points and the mean CHDI was 32.63 (95% CI 31.50:33.78), on a total score ranging from 0 to 110 points. PHDI showed a significant positive association with the final CHDI score and components of fruits, vegetables, and legumes, and a negative association with Ultra-processed Food (UPF) (p

Introdução. A COVID-19 impactou a garantia de uma alimentação adequada e saudável, inclusive entre universitários, que parecem constituir um grupo suscetível à Insegurança Alimentar (IA). Objetivo. Verificar a associação entre IA e marcadores de consumo alimentar em universitários durante a pandemia de COVID-19. Materiais e métodos. Estudo transversal com 5407 estudantes de instituições de ensino superior de todas as regiões do Brasil. Os dados foram coletados entre agosto/2020 e fevereiro/2021. O consumo alimentar foi avaliado por marcadores de alimentação saudável utilizados num inquérito nacional de saúde (VIGITEL). Os níveis de IA foram classificados pela Escala Brasileira de Insegurança Alimentar em Segurança Alimentar (SA) e IA leve, moderada e grave. A associação entre IA e marcadores de consumo foi avaliada por meio de regressão logística, considerando frequência semanal de consumo < 3 dias e ≥ 3 dias. Resultados. 37% dos universitários estavam em algum grau de IA. Verificou-se maior chance de baixa frequência de consumo de feijão (OR 1,81), verduras e legumes (OR 4,76), frutas (OR 3,99), lácteos (OR 3,98) e carnes (OR 3,41), e maiores chances de maior consumo de frango (OR 1,14) e ovos (OR 2,04) entre aqueles em IA (p

RESUMO Objetivou-se caracterizar o cenário da aquisição dos alimentos provenientes da Agricultura Familiar (AF) para o Programa Nacional de Alimentação Escolar (PNAE) nos municípios do Rio Grande do Norte. Pesquisa avaliativa com delineamento ecológico, utilizando dados do Centro Colaborador em Alimentação e Nutrição Escolar da Universidade Federal do Rio Grande do Norte em 2017 e 2018. Avaliaram-se 31 municípios, analisando o percentual de aquisição de alimentos da AF para a alimentação escolar, além das possíveis dificuldades nesse processo, utilizando variáveis relacionadas com governança e gestão, estabilidade e disponibilidade de alimentos. Dos municípios avaliados, mais de 50% adquiriram alimentos da AF no ano anterior e afirmaram a compra no ano atual. Todos relataram empregar o modelo de gestão centralizada, 29% declararam aquisição menor que 30%, 9,7%, aquisição acima de 30%, e 61,3% não souberam informar. Quanto às principais dificuldades relacionadas com governança e gestão, a articulação intersetorial e o edital de chamada pública ganharam destaque. Sobre a estabilidade de alimentos, destacaram-se as condições higienicossanitárias necessárias, e em relação à disponibilidade de alimentos, a aquisição de alimentos orgânicos mostrou-se como uma dificuldade elencada por 80,6% dos municípios.

IntroductionThe current food system is associated with negative impacts on health, food insecurity and environmental harm. Sustainable diets have attracted increasing interest and novel proposals with a global scope have emerged. This scoping review aims to give an overview of the analysis of all the available evidence related to the sustainable diet indices that have been developed based on the EAT-Lancet Commission.MethodsSearches were conducted in the PubMed, Embase, Web of Science, Scopus and Science Direct databases. This review was conducted following the PRISMA-ScR guidelines. The target population were studies addressed the use of an index or metric for assessing sustainable diets based on the EAT-Lancet Commission Summary Report were included. PCC acronym was used in the design of the study to describe eligibility criteria: P (Population)-Indexes; C (Concept)-Sustainable diets; C (Context)-Knowledge on the structure and applicability of measurement indices of sustainable diets based on EAT-Lancet recommendations available in the literature. Study eligibility criteria were restricted to papers published in English, from January 2019 through October 2022, with no population restriction.ResultsA total of 1,458 papers were retrieved, 14 of which were included in the review. Seven measures of sustainable diets were identified as follow: EAT-Lancet diet score (ELD-I), New EAT-Lancet diet score (EAT), Planetary Health Diet Index (PHDI), Sustainable Diet Index (SDI), Sustainable-HEalthy-Diet (SHED), novel Nutrient-Based EAT index (NB-EAT) and World Index for Sustainability and Health (WISH). Most studies were conducted in developed countries, where greater adherence to this type of diet was found. Estimated greenhouse gas emissions was the most reported indicator of sustainability, followed by diet quality and the benefits of sustainable diets with regards to health outcomes.DiscussionWe identified barriers that hinder progress towards sustainable diets, including the difficulty of comparing different indices and the tendency to neglect social aspects and the lack of common definitions and metrics. Despite being challenge, we highlight the importance of using indices that assess sustainable diets that harmonize various indicators, as recommended by the EAT-Lancet Commission, in order to promote positive changes towards a more sustainable future.

BackgroundWeight measurement is important in the nutritional anthropometric monitoring of older adults. When this measurement is not possible, estimates may be used.AimDeveloping and validating weight predictive equations for older adult residents in long-term care institutions in Brazil.Subjects and methodsThe sample comprised 393 older adult residents in long-term care institutions. Data were collected in two stages, with 315 older adults in the first and 78 in the second. We have measured the arm, calf, and waist circumferences, as well as the triceps and subscapular skinfold and knee height. Multiple linear regression was used to develop the equations, which were evaluated through the coefficient of determination, standard error of estimation, Akaike information criterion, intraclass correlation coefficient (ICC), and Bland-Altmann plot.ResultsFive models with different anthropometric measurements were developed, (1) arm circumference as a discriminant variable (ICC: 0.842); (2) best statistical fit for men and women (ICC: 0.874) and its stratification by sex (3) (ICC: 0.876); (4) easy-to-perform measurement for men and women (ICC: 0.842) and its stratification by sex (5) (ICC: 0.828).ConclusionFive models for estimating the weight of older adult residents in long-term care institutions were developed and validated. The choice to use the models should be based on the physical capacity of the older adults to be evaluated.

Understanding individual perception of Quality of Life (QoL) can help combat social and health inequalities. We aimed to identify factors associated with Low Perceived Quality of Life (LPQoL) in 295 adults and older adults with food security and food insecurity, in the city of Natal, Brazil. A cross-sectional study was conducted from June to December 2019, with collection of data on socioeconomic demographic status, lifestyle information, non-communicable diseases (NCDs) and risk factors, emotional disorders, food (in) security and quality of life. To assess food insecurity, the Brazilian Scale of Food Insecurity—EBIA was used, and the WHOQOL-Bref questionnaire was used to assess quality of life. Poisson's Regression was used to verify associations between variables and LPQoL, stratifying the sample into food secure (FS) and food insecure (FI) groups. In the FI group, being overweight, older adult, having no partner, drinking alcoholic beverages twice a week or more, and not having daily availability of water were associated with LPQoL, and in the FS group, having diabetes, monthly family income in the 1st and 2nd tertiles, and never having studied was associated with LPQoL. Reporting emotional disorders and sleeping < 7 h/day were associated with LPQoL in both FI and FS groups. LPQoL was associated with the occurrence of NCDs and risk factors, and emotional disorders, regardless of the food security measure. However, the lack of adequate access to water highlights the social vulnerability of the FI group.

Abstract Background Against a backdrop of population aging and improving survival rates for chronic noncommunicable diseases (CNCD), researchers are placing growing emphasis on health-related quality of life (HRQoL). The aim of this study was to identify the QoL assessment instruments used in population-based studies with adults conducted around the world. Methods A systematic review of original research published in all languages between 2008 and 2018 was conducted. Systematic reviews and meta-analyses were excluded. Results Sixty-three articles (38.1% conducted in the Americas) fitted the eligibility criteria. Based on the AHRQ checklist for cross-sectional studies and the Newcastle-Ottawa scale for cohort studies, methodological quality was shown to be fair in the majority of studies (55.6%) and good in 44.4%. The country with the highest number of publications was Brazil (20.6%). Twelve types of generic instruments and 11 specific instruments were identified. The generic instrument SF-36 was the most frequently used measure (33.3% of studies). In-home interviewing was exclusively used by 47.6% of the studies, while 39 studies (61.9%) reported the use of self-administered questionnaires. Over two-thirds of the studies (34.9%) used questionnaires to investigate the association between chronic diseases and/or associated factors. Conclusions It was concluded that the wide range of instruments and modes of questionnaire administration used by the studies may hinder comparisons between population groups with the same characteristics or needs. There is a lack of research on QoL and the factors affecting productive capacity. Studies of QoL in older persons should focus not only on the effects of disease and treatment, but also on the determinants of active aging and actions designed to promote it. Further research is recommended to determine which QoL instruments are best suited for population-based studies.

Environmental footprints are indicators that can be used to estimate the impacts of diet on the environment. Since contemporary dietary practices are related to negative environmental impacts, this paper aims to describe a systematic review protocol to investigate the environmental footprints of food consumption by adults and elderly individuals worldwide. This protocol was developed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Search strategies and records of evidence searched in previously defined electronic databases will be defined. Original, population-based articles investigating the environmental footprints of food consumption by adults and the elderly will be included. Two independent reviewers will conduct the study selection and data extraction steps. Critical appraisal of the included studies will be based on the Newcastle-Ottawa Scale. For data synthesis, a narrative synthesis and, if possible, also a meta-analysis will be performed. The systematic review produced from this protocol will provide evidence for data synthesis of the environmental impact through environmental footprints of food consumption of the adult and elderly population from different territories and the footprint assessment tools used around the world. Therefore, it is a gap that needs to be filled because knowing these impacts will be important to inform the development of public policies that encourage healthy and sustainable food in the face of climate and epidemiological changes.

Introdução: O crescimento de transtornos alimentares entre adolescentes demanda a identificação de comportamentos alimentares desordenados e de determinantes sociais relacionados a esses agravos. Objetivo: Avaliar as prevalências de comportamentos alimentares desordenados (CAD) entre adolescentes escolares brasileiros e suas associações com determinantes sociais em saúde. Metodologia: Foram avaliados 16.556 adolescentes da Pesquisa Nacional de Saúde do Escolar de 2015. Regressões de Poisson estimaram modelos multivariados relacionados a métodos compensatórios inadequados para controle de peso (laxativos/purgativos ou medicamentos/produtos). Resultados: A prevalência dos CAD para perda de peso no grupo foi 11,3% (IC95%:10,6-12,0%) tendo como fatores associados: sexo masculino, cor/raça não branca, 14 anos ou menos, excesso de peso, insatisfação com a imagem corporal, frequentar fast food, trabalhar, não realizar regularmente refeições com responsáveis, ter mães com menor escolaridade, domicílio com cinco ou mais moradores, vivência da fome no domicílio e estudar em escolas públicas. Conclusão: Esses comportamentos desordenados para perda de peso foram mais prevalentes entre adolescentes com maior insatisfação corporal e vivendo em situações de mais vulnerabilidade social.

Introdução: O envelhecimento da população mundial é uma conquista da humanidade, que também se mostra um dos maiores desafios, uma vez que ocasionará novos paradigmas e demandas políticas, sociais, econômicas e de saúde. Desse modo, torna-se essencial discutir os aspectos que envolvem a pessoa idosa e a Atenção Primária à Saúde (APS). Objetivo: Realizar uma análise bibliométrica da produção científica referente aos fatores relacionados com a pessoa idosa e a APS. Métodos: Trata-se de uma revisão bibliométrica que utilizou os termos “primary health care” AND “aged*” na base de dados Web of Science, entre os anos de 1945 e 2016. O estudo analisou os registros com base em revisão de literatura sobre a temática em questão com o auxílio do software HistCite. Resultados: Foram identificados 700 artigos em 313 periódicos, de 2.834 autores vinculados a 1.138 instituições de 61 países, o que totalizou 19.745 referências, com média de aproximadamente 28 referências por artigo. A revista Scandinavian Journal of Primary Health Care possui 4% dos textos e o International Journal of Geriatric Psychiatry, o maior fator de impacto. Os autores mais citados estão reunidos em apenas cinco universidades, com destaque para a Linkoping University, que detém 4% do total de publicações, e três países: Suécia, Brasil e Estados Unidos da América. O Brasil ocupa a primeira colocação, com 2% dos textos. Conclusões: Os estudos revelam aspectos importantes associados à pessoa idosa e à APS, como problemas de inobservância quanto aos cuidados de saúde para essa população, tanto por profissionais quanto pelos próprios idosos, apontando para a desumanização e consequente falta de priorização dessa faixa etária no âmbito da saúde. Com o envelhecimento das populações, é imprescindível que esse tema venha a ser priorizado, ampliando o debate sobre essa transição demográfica e suas consequências para toda a população e visando a alternativas que possam minimizar os impactos dela, bem como a novos paradigmas para produtos e serviços voltados para a população idosa. Isso especialmente na atenção primária, que é porta de entrada para todo o serviço de saúde e principal elo social entre o idoso e a qualidade de vida. Destaca-se ainda a necessidade de educação continuada dos profissionais e de aperfeiçoamento desse nível de atenção para o atendimento a essa população, quantitativamente cada vez maior.

The analysis of dietary environmental impacts has proven to be an important tool for guiding the adoption of healthier and more sustainable diets. This study aimed to estimate the dietary carbon (CF), water (WF), and ecological (EF) footprints of residents in the city of Natal, Brazil; the study also aimed to verify their association with socioeconomic factors and food purchase practices. This is a cross-sectional study that used dietary data from 411 adults and elderlies, which was collected via a questionnaire that applied to the respondents. The results showed that the dietary CF was 1901.88 g CO2 eq/day/1000 kcal, the WF was 1834.03 L/day/1000 kcal, and the EF was 14.29 m2/day/1000 kcal. The highest environmental footprint values showed an association (p ≤ 0.05) with the factors of male sex, white ethnicity, and higher income and schooling, whereas the lowest environmental footprint values were associated with social vulnerability variables such as female sex, non-white ethnicity, and lower income and schooling (p ≤ 0.05). Moreover, people with lower environmental footprints consumed less fast food, had fewer meals at snack bars, and used food delivery services less often than those with higher footprints. The foods that most contributed to the CFs and WFs were beef and chicken, while fish and beef contribute the most to the EFs. The data in the present study show that a diet with a lower environmental impact is not always equal to a sustainable diet. This relationship is paradoxical and relates to food justice, as people with lower environmental footprint values are the same ones with worse socioeconomic conditions. In this sense, is it essential to consider the influence of the social context when assessing dietary environmental impacts and when assessing actions that promote healthier and more sustainable diets.

(1) Background: The present study analyzed the prevalence of dietary and nutritional profiles among Brazilian adolescents and their associations with social determinants of health. (2) Methods: A population-based survey was administered to 16,409 adolescents assessed by the 2015 National School Health Survey. A multivariate model of dietary and nutritional profiles was estimated from correspondence analysis. (3) Results: The dietary and nutritional profiles more prevalent among Brazilian adolescents were “lower nutritional risk dietary pattern and eutrophic” (42.6%), “lower nutritional risk dietary pattern and overweight” (6.8%), and “higher nutritional risk dietary pattern and overweight” (6.0%). Healthier profiles were associated with less urbanized territories, health-promoting behaviors, and families with worse material circumstances. The less healthy profiles were associated with more urbanized environments, health risk behaviors, and families with better material circumstances. (4) Brazilian adolescents have different dietary and nutritional profiles that are characterized by sociopolitical and economic contexts, family material and school circumstances, and the behavioral and psychosocial health factors of the individuals. All of this points to the social determination of these health problems among adolescents in Brazil.

(1) Background: The purpose of this study was to identify the prevalence of obesity and stunting among Brazilian adolescents and its associations with social determinants of health (individual, family, and school), grounded on the necessity of investigating the determinants of nutritional problems within this population. (2) Methods: A population-based survey was administered to 16,556 adolescents assessed by the 2015 National School Health Survey. Multivariate models of obesity and stunting were estimated from Multilevel Poisson Regressions. (3) Results: The prevalence of obesity among Brazilian adolescents (10.0%; 95% CI: 9.4–10.6) was associated directly with indifference or dissatisfaction with body image, with eating breakfast four or fewer days a week, living with up to four people in the household, studying in private schools, and being from the South region, and was inversely associated with being female, 15 years old or older, with having the highest nutritional risk eating pattern, dining at fast-food restaurants, and eating while watching television or studying. The prevalence of stunting (2.3%; 95% CI: 2.0–2.8) was directly associated with the age of 15 years or older, and inversely associated with the lower number of residents living in the household, maternal education—decreasing gradient from literate to college level education, studying in urban schools, and being from the South and Central-West regions. (4) Conclusions: Obesity in adolescence presented behavioral determinants. Stunting and obesity have structural social determinants related, respectively, to worse and better socioeconomic position among Brazilian adolescents.

The increase in the availability of processed and ultra-processed foods has altered the eating patterns of populations, and these foods constitute an exposure factor for the development of arterial hypertension. This systematic review analyzed evidence of the association between consumption of processed/ultra-processed foods and arterial hypertension in adults and older people. Electronic searches for relevant articles were performed in the PUBMED, EMBASE and LILACS databases. The review was conducted following the PRISMA guidelines and the Newcastle–Ottawa Scale. The search of the databases led to the retrieval of 2323 articles, eight of which were included in the review. A positive association was found between the consumption of ultra-processed foods and blood pressure/arterial hypertension, whereas insufficient evidence was found for the association between the consumption of processed foods and arterial hypertension. The results reveal the high consumption of ultra-processed foods in developed and middle-income countries, warning of the health risks of such foods, which have a high energy density and are rich in salt, sugar and fat. The findings underscore the urgent need for the adoption of measures that exert a positive impact on the quality of life of populations, especially those at greater risk, such as adults and older people.

ABSTRACT Objective: To evaluate the feeding practices for infants under one year of age, according to food and nutrition policies. Methods: This is a descriptive cross-sectional study based on secondary data from the Chamada Neonatal project (research on prenatal, childbirth, and infant care) in the state of Rio Grande do Norte. The sample analyzed comprised 837 mother/child (under one year of age) pairs. We found a prevalence of data on exclusive breastfeeding (EBF) in the first hour of life - partial and total -, as well as on food consumed by children 24 hours prior to the interview. We estimated the probability of consumption according to the child’s age in days using the probit analysis. Results: Among the interviewed mothers, 64.8% (95%CI 62.4-70.8) declared breastfeeding in the first hour of life, and 60% (95%CI 56.41-63.07) of the children were still breastfed at the end of their first year of life. The median duration of EBF was 63 days (95%CI 60-67). Water or tea, dairy products, fruits, and vegetables were introduced early, with medians lower than 180 days. The probit analysis revealed that the consumption of breast milk tended to decrease and food intake to increase as the child gets older, with exponential growth in the “unhealthy food” group. Conclusions: Although most children were breastfed up to one year of life, few did so exclusively. Foods were introduced early, with increased consumption of unhealthy ones, resulting in inadequate dietary quality according to recommendations from food and nutrition public policies.

Undergraduates may face challenges to assure food security, related to economic and mental distress, especially during the COVID-19 pandemic. This study aimed to assess food insecurity and its associated factors in undergraduates during the COVID-19 pandemic. An online cross-sectional study was conducted from August 2020 to February 2021 with 4775 undergraduates from all Brazilian regions. The questionnaire contained socio-economic variables, the validated Brazilian food insecurity scale, and the ESQUADA scale to assess diet quality. The median age of the students was 22.0 years, and 48.0% reported income decreasing with the pandemic. Food insecurity was present in 38.6% of the students, 4.5% with severe food insecurity and 7.7% moderate. Logistic regressions showed students with brown and black skin color/race presented the highest OR for food insecurity; both income and weight increase or reduction during the pandemic was also associated with a higher OR for food insecurity, and better diet quality was associated with decreased OR for food insecurity. Our study showed a considerable presence of food insecurity in undergraduates. Policy for this population must be directed to the most vulnerable: those with brown and black skin color/race, who changed income during the pandemic, and those presented with difficulties maintaining weight and with poor diet quality.

Changes in eating behavior of adolescents are associated with high consumption of processed and ultra-processed foods. This study evaluated the association between these foods and the prevalence of inadequate micronutrient intake in adolescents. A cross-sectional study was conducted with 444 adolescents from public schools in the city of Natal, northeastern Brazil. The adolescents' habitual food consumption was evaluated using two 24-hour dietary recalls. Foods were categorized according to the degree of processing (processed and ultra-processed) and distributed into energy quartiles, using the NOVA classification system. Inadequacies in micronutrient intake were assessed using the estimated average requirement (EAR) as the cutoff point. Multivariate logistic regression models were used to estimate the relationship between energy percentage from processed and ultra-processed foods and prevalence of inadequate micronutrient intake. The mean (Standard Deviation (SD)) consumption of total energy from processed foods ranged from 5.8% (1.7%) in Q1 to 20.6% (2.9%) in Q4, while the mean consumption of total energy from ultra-processed foods ranged from 21.4% (4.9%) in Q1 to 61.5% (11.7%) in Q4. The rates of inadequate intake of vitamin D, vitamin E, folate, calcium, and selenium were above 80% for both sexes across all age groups. Energy consumption from processed foods was associated with higher prevalence of inadequate selenium intake (p < 0.01) and lower prevalence of inadequate vitamin B1 intake (p = 0.04). Energy consumption from ultra-processed foods was associated with lower prevalence of inadequate zinc and vitamin B1 intake (p < 0.01 and p = 0.03, respectively). An increase in the proportion of energy obtained from processed and ultra-processed foods may reflect higher prevalence of inadequate selenium intake and lower prevalence of vitamin B1 and zinc inadequacy.

RESUMO: Introdução: Na impossibilidade de mensuração do peso em idosos, métodos de estimativa podem ser empregados. Entretanto, tais métodos nem sempre são aplicáveis, podendo levar a erros de estimativa que comprometem tanto a prática clínica quanto resultados em estudos epidemiológicos. Objetivo: Comparar e validar métodos de estimativa de peso em idosos residentes em instituições de longa permanência de Natal, Rio Grande do Norte. Métodos: Avaliaram-se as equações qualitativamente pela reprodutibilidade das medidas que as compunham e, quantitativamente, pela diferença média entre o peso mensurado e os estimados, e utilizado o teste t de Student para amostras pareadas ou ANOVA, coeficiente de determinação (R²), raiz do erro quadrático médio (REQM), coeficiente de correlação intraclasse (CCI) e análise gráfica de resíduos. Adotou-se como valor de significância p < 0,05. Considerou-se aplicável quando a equação apresentava R² > 0,7; menor REQM dentre as equações avaliadas; CCI > 0,7; e respectivo intervalo de confiança 95% com menor distância entre os limites inferior e superior. Resultados: Avaliaram-se 315 idosos de 10 instituições de longa permanência de Natal. O peso corporal médio foi maior nos idosos mais jovens e sem restrição de mobilidade. A análise qualitativa mostrou a equação 5 como a de melhor reprodutilidade, uma vez que não utiliza medidas de dobras cutâneas. A análise quantitativa revelou a equação 5 como a de melhor aplicabilidade em toda a população avaliada e nos diferentes sexos, faixas etárias (60 a 69 anos, 70 a 79 anos e 80 anos ou mais) e condição de restrição de mobilidade. Conclusão: A equação 5 foi aplicável para a estimativa de peso na população avaliada e nos diferentes estratos analisados.

Estimating equations can be used when measuring the height of elderly persons is not possible. However, such methods are not always applicable; therefore, it is necessary to consider several aspects, such as sex, age, and ethnicity of the studied population to generate these equations. This study aimed to compare and validate methods of estimating the height of the Brazilian elderly nursing home residents. An accuracy study was conducted with 168 elderly persons. A total of 23 equations were quantitatively evaluated by plotting the differences in means, the Student's t-test for paired samples, the coefficient of determination (R2), the root-mean-square error (RMSE), the interclass correlation coefficient (ICC), and by graphic analysis of the residuals. A significance value of p 0.7, the lowest RMSE among the equations evaluated, ICC >0.7, and a confidence interval of 95%, with the smallest difference between the upper and lower limits. A greater mean height was noted among younger elderly persons and elderly men compared to up to 80 years and women elderly. Quantitative analysis revealed that equation for Puerto Ricans, using knee height and age, was the most applicable for the overall population (ICC = 0.802). The same equation was applicable for the elderly Brazilian male participants (ICC = 0.838) and for those aged 60-69 years (ICC = 0.895). None of the equations used were applicable for the height estimation of elderly women or individuals aged 70 years or more.

O trabalho apresenta uma experiência educativa, realizada no projeto EM TORNO DA MESA, dentro da temática de Segurança Alimentar e Nutricional (SAN) em comunidades costeiras tradicionais, localizadas na Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão, no município de Macau, Estado do Rio Grande do Norte (RN), Brasil. Com o objetivo de contribuir para otimização do aproveitamento do pescado e utilização dos subprodutos para possibilitar alternativas de produção para subsistência, o alimento para melhoria da saúde e a educação para autonomia, foram realizados encontros, oficinas pedagógicas, mostras, feiras e eventos do projeto EM TORNO DA MESA, os quais foram espaços importantes de formação técnica e social e de desenvolvimento humano. Durante este processo, ocorreu a participação efetiva de 53 pessoas dessas comunidades. Nessa trajetória, foram revelados os princípios da SAN, mediante as boas práticas de manipulação do pescado, desde o mar até a mesa, e concretizado o ciclo positivo da produção, que incluiu as técnicas do beneficiamento e a comercialização de produtos alimentares à base de peixes de baixo valor comercial. A experiência tornou evidente a necessidade do fortalecimento da formação técnica e social, respeitando a cultura alimentar local, da otimização do arranjo da pesca artesanal e da busca de alternativas de comercialização na Reserva.

ABSTRACT OBJECTIVE To develop a quantitative Food Frequency Questionnaire (FFQ) for adults in the Northeast region of Brazil, in order to identify the frequency of consumption of foods considered to be of protection and risk for chronic non-communicable diseases (NCDs), grouping food items by processing level. METHODS To develop the FFQ, data from 7,516 adults from Northeastern Brazil were used, extracted from the 2008–2009 Household Budget Survey. The food lists were elaborated according to the methodology of the relative contribution of each item, identifying foods with the highest relative contribution for macronutrients, fiber, saturated fat, trans fat, sodium and potassium. All foods whose contribution sum was up to 90% composed such lists. The final structure of the FFQ organized the food items in order to respect the mental image of the meals. RESULT The FFQ resulted in 83 food items, distributed in minimally processed, processed and ultra-processed. We chose the previous year as the time to estimate food consumption, and frequency options ranged from “never” to “10 times”. The instrument includes guidelines for filling and collects data on serving sizes (small, medium, large and extra-large), as well as additional information on culinary preparations. There was a high percentage of people who were overweight (44.1%). CONCLUSION The study culminated in an FFQ to identify the frequency of consumption of foods considered protective and risk for NCDs. The instrument can support epidemiological studies that evaluate outcomes related to the diet of adults considering the level of food processing, in accordance with the Guia alimentar para a população brasileira .

Resumo: Objetivou-se identificar perfis multidimensionais de fatores de risco relacionados ao estilo de vida, com a verificação de características sociodemográficas e de autopercepção de saúde associadas. Utilizaram-se dados da Pesquisa Nacional de Saúde (2013) de 45.881 indivíduos acima de 30 anos. Para a identificação dos perfis, foi utilizado o método Grade of Membership (GoM), com a inclusão de 12 variáveis. A análise de características associadas foi realizada por meio do teste qui-quadrado de Pearson e de regressão logística. Foram identificados dois perfis: “perfil saudável” (61,6%) e “perfil de risco” (38,4%). O “perfil saudável” é caracterizado pelo consumo adequado de frutas, vegetais, peixes, bem como pelo consumo não regular de refrigerante, carne com gordura e feijão; apresenta excesso de peso e faz atividade física recomendada no lazer. O “perfil de risco”, por sua vez, é caracterizado pelo não consumo de marcadores saudáveis, exceto o consumo de feijão, pelo consumo de todos os marcadores não saudáveis de alimentação, pelo hábito de substituir refeições por lanches, pelo consumo de álcool, uso de tabaco e por não serem fisicamente ativos no lazer. O perfil saudável associou-se ao sexo feminino, como também a idosos, brancos, residentes no Norte e Nordeste do Brasil, viúvos e casados, com maior escolaridade e com melhor autoavaliação de saúde. Já o perfil de risco se associou ao sexo masculino, como também a adultos jovens, residentes no Centro-oeste e Sul, solteiros, com menor escolaridade e com pior autoavaliação de saúde. Embora mais prevalente, o percentual de indivíduos com pertencimento total ao perfil saudável foi baixo. Fatores de risco relacionados ao estilo de vida estão associados a características sociodemográficas.

Inflammatory bowel diseases (IBD) are chronic conditions arising from an intricate interplay of genetics and environmental factors, and are associated with gut dysbiosis, inflammation, and gut permeability. In this study, we investigated whether the inflammatory potential of the diet is associated with the gut microbiota profile, inflammation, and permeability in forty patients with IBD in clinical remission. The dietary inflammatory index (DII) score was used to assess the inflammatory potential of the diet. The fecal microbiota profile was analyzed using 16SrRNA (V3–V4) gene sequencing, while fecal zonulin and calprotectin levels were measured with enzyme-linked immunosorbent assays. We found a positive correlation between the DII score and elevated calprotectin levels (Rho = 0.498; p = 0.001), but not with zonulin levels. Although α- and β-diversity did not significantly differ across DII quartiles, the most pro-inflammatory diet group exhibited a higher fecal abundance of Veillonella rogosae (p = 0.026). In addition, the abundance of some specific bacteria sequences showed an exponential behavior across DII quartiles and a correlation with calprotectin or zonulin levels (p ≤ 0.050). This included a positive correlation between sq702. Veillonella rogosae and fecal calprotectin levels (Rho = 0.419, p = 0.007). DII, calprotectin, and zonulin levels were identified as significant predictors of 6-month disease relapse (p ≤ 0.050). Our findings suggest a potential relationship of a pro-inflammatory diet intake with Veillonella rogosae and calprotectin levels in IBD patients in clinical remission, which may contribute to disease relapse.

Resumo O objetivo do artigo é analisar o efeito da compra direta de alimentos da agricultura familiar para alimentação escolar sobre o déficit de estatura em crianças menores de cinco anos, entre 2013 e 2017, no Brasil. O método utilizado é o estudo ecológico e longitudinal, em que a coleta de dados ocorreu em diferentes bancos de dados. A análise foi realizada por meio do teste t para amostras independentes, a fim de comparar as médias entre as variáveis déficit de estatura e compras da agricultura familiar. Além disso, uma análise multivariável foi feita por meio da regressão linear múltipla. Verificou-se uma diferença de médias na prevalência do déficit de estatura significativa entre os municípios que compraram menos de 30% e aqueles que adquiriram 30% ou mais de alimentos da agricultura familiar para alimentação escolar, com 1,47 pontos de diferença. O modelo de regressão linear mostrou que a cada ponto percentual de aumento na compra de alimentos da agricultura familiar para a alimentação escolar pelo município, haverá, em média, uma diminuição 0,55 pontos na prevalência do déficit de estatura, independentemente das demais variáveis. Assim, conclui-se que a compra de alimentos da agricultura familiar para alimentação escolar no Brasil pode contribuir para a redução da prevalência do déficit de estatura em crianças menores de cinco anos.
