Associação entre insegurança e consumo alimentar em universitários brasileiros durante a pandemia de COVID-19 / Association between food insecurity and consumption in Brazilian university students during the COVID-19 pandemic

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<0,05). Em sua maioria, os valores foram mais expressivos quanto maior o grau de IA. Conclusões. Maiores níveis de IA mostraram-se associados a uma menor chance de consumo alimentar saudável por universitários. Instituições de ensino superior podem executar papéis importantes no combate e assistência à IA nessa população(AU)

Introduction. COVID-19 has impacted access to an adequate and healthy diet, including university students, who seem to constitute a group susceptible to Food Insecurity (FI). Objective. To verify the association between FI and food consumption markers in university students during the COVID-19 pandemic. Materials and Methods. We conducted a cross- sectional study with 5407 students from higher education institutions from all regions of Brazil. Data were collected between August/2020 and February/2021. We evaluated food consumption using the healthy eating markers from a Brazilian national health survey (VIGITEL). We classified the FI levels according to the Brazilian Food Insecurity Scale into Food Security (FS) and mild, moderate, and severe FI. We evaluated the association between FI and consumption markers using logistic regression, considering the weekly frequency of consumption of < 3 days and ≥ 3 days. Results. 37% of the university students had in some degree of FI. We found a greater chance of lower frequency of consumption of beans (OR 1.81), vegetables (OR 4.76), fruits (OR 3.99), dairy products (OR 3.98), and meat (OR 3. 41), and greater chances of increased consumption of chicken (OR 1.14) and eggs (OR 2.04) among those in FI (p<0.05). Overall, the values were more expressive the higher the degree of FI. Conclusions. Higher FI levels were associated with a lower chance of healthy food consumption in university students. Higher education institutions can play a relevant role in addressing and administering the FI in this population(AU)

Biochemical phenotyping of paroxysmal nocturnal hemoglobinuria reveals solute carriers and ß-oxidation deficiencies.

INTRODUCTION: Paroxysmal nocturnal hemoglobinuria (PNH) is a clonal disease of hematopoietic cells with a variable clinical spectrum characterized by intravascular hemolysis, high risk of thrombosis, and cytopenias. To understand the biochemical shifts underlying PNH, this study aimed to search for the dysfunctional pathways involved in PNH physiopathology by comparing the systemic metabolic profiles of affected patients to healthy controls and the metabolomic profiles before and after the administration of eculizumab in PNH patients undergoing treatment. METHODS: Plasma metabolic profiles, comprising 186 specific annotated metabolites, were quantified using targeted quantitative electrospray ionization tandem mass spectrometry in 23 PNH patients and 166 population-based controls. In addition, samples from 12 PNH patients on regular eculizumab maintenance therapy collected before and 24 hours after eculizumab infusion were also analyzed. RESULTS: In the PNH group, levels of the long-chain acylcarnitines metabolites were significantly higher as compared to the controls, while levels of histidine, taurine, glutamate, glutamine, aspartate and phosphatidylcholines were significantly lower in the PNH group. These differences suggest altered acylcarnitine balance, reduction in the amino acids participating in the glycogenesis pathway and impaired glutaminolysis. In 12 PNH patients who were receiving regular eculizumab therapy, the concentrations of acylcarnitine C6:1, the C14:1/C6 ratio (reflecting the impaired action of the medium-chain acyl-Co A dehydrogenase), and the C4/C6 ratio (reflecting the impaired action of short-chain acyl-Co A dehydrogenase) were significantly reduced immediately before eculizumab infusion, revealing impairments in the Acyl CoA metabolism, and reached levels similar to those in the healthy controls 24 hours after infusion. CONCLUSIONS: We demonstrated significant differences in the metabolomes of the PNH patients compared to healthy controls. Eculizumab infusion seemed to improve deficiencies in the acyl CoA metabolism and may have a role in the mitochondrial oxidative process of long and medium-chain fatty acids, reducing oxidative stress, and inflammation.

Introduction:SystemicArterial Hypertension is a chronic disease that affects most Brazilian older adults and is one of the main causes of premature deaths and functional disabilities that cause cardiovascular and brain complications. Obesityis among the several predisposing factorsassociatedwithhypertension. Objective:To evaluate the association between SAHand anthropometric indicators in older adultsof the Brazuca Natal study.Methodology: Cross-sectional population-based study with 191 older adults in the city of Natal-RN.Sociodemographic, economic and anthropometric data (weight, height, waist circumference,and hip circumference),Body Mass Index, Waist-Height Ratio and Waist-Hip Ratio were collected. Hypertension was self-reported. Data were analyzed using the SPSS software, version 20.0. The Student's t-test was used to compare themeans of the variables according to sexand presence of hypertension. The association between the presence of the disease and the variables wasperformed by Poisson regression, with crude and adjusted prevalence ratios and respectiveconfidence intervals (95%).Results:The majority of the elderly were female (55%), with a mean age of 69.48 years (SD = 7.38) andBody Mass Indexof 28.46 (SD = 5.25), 59.4% were overweight and 60.1% had hypertension. Mean Body Mass Index, hip circumference and Waist-Height Ratiovalues were higher in women (p<0.05). The age and anthropometric indicators values were higher among the older adults with hypertension (p<0.05). We found that the presence of hypertension was associated with body weight and Body Mass Index,in the crude model and only with body weight in the adjusted model. Conclusions:Anthropometric indicators of easy application and lowcost such as waist circumference can be efficient todetect hypertension in older adults (AU).

Dietary iron intake over two post-fortification periods in Brazil: data from the National Dietary Surveys 2008-2009 and 2017-2018.

We aimed to assess the dietary Fe intake and the prevalence of inadequate Fe intake over two post-fortification periods in Brazil. The intake was analysed according to sex, life stage, geographic region and stratum of family income per capita. Excluding pregnant and lactating women, this population-based study included 32 749 and 44 744 participants aged ≥ 10 years from the National Dietary Survey-Brazilian Household Budget Surveys 2008-2009 and 2017-2018, respectively. The National Cancer Institute method was used to predict usual dietary Fe intakes. The prevalence of Fe intake inadequacy was estimated following a probabilistic approach for women of childbearing age or with the Estimated Average Requirement cut-off point method. Over an interval of 10 years, the mean Fe intake remained almost unchanged for most sex-age groups, except for women of childbearing age. In this specific group, the prevalence of Fe intake inadequacy was > 20 % in 2008-2009 and have increased to > 25 % in 2017-2018, with the highest reductions in mean Fe intake found in the highest income strata and richest Brazilian regions. Meanwhile, the highest prevalence of Fe intake inadequacy (> 40 %) occurred among the poorest women aged 31-50 years from the lowest family income stratum, irrespective of the study period. Beans were the main Fe source, while fortified breads, pastas, pizzas, cakes and cookies contributed approximately 40 % of the Fe intake. The results provide important insights into the long-standing dietary impacts of food fortification, which can guide future (re)formulation of effective public health strategies to combat Fe deficiency.

Adesão à dieta EAT-Lancet e sua relação com insegurança alimentar e renda em uma amostra de base populacional brasileira / Adhesión a la dieta EAT-Lancet y su relación con la inseguridad alimentaria y los ingresos en una muestra de base poblacional brasileña / Adherence to the EAT-Lancet diet and its relation with food insecurity and income in a Brazilian population-based sample

Resumo: O objetivo deste estudo foi investigar a relação entre a adesão à dieta planetária com a situação de segurança alimentar e nutricional e renda familiar per capita, utilizando amostra representativa da população brasileira. Entre os dados da Pesquisa de Orçamentos Familiares (POF) de 2017-2018, os indicadores de desigualdade selecionados para a análise foram as informações sobre renda familiar per capita e segurança alimentar e nutricional. Também foram considerados dados de consumo alimentar individual de 46.164 brasileiros com idade ≥ 10 anos, obtidos por meio de recordatórios alimentares de 24 horas, no Inquérito Nacional de Alimentação, conduzido junto à POF 2017-2018. O Índice de Dieta Planetária (PHDI) foi empregado para mensurar a adesão à dieta planetária. Dados sociodemográficos foram expressos como frequência (%), com análise da média e intervalo de 95% de confiança (IC95%) do escore do PHDI. A relação entre segurança alimentar e nutricional e renda com o escore do PHDI foi testada em modelos de regressão linear múltipla. Os cálculos foram executados no software Stata, adotando uma significância de 5%. Menores médias do PHDI foram observadas entre indivíduos em insegurança alimentar, do sexo masculino, < 20 anos, pardos e indígenas, com renda < 0,5 salário mínimo, domiciliados na zona rural e das regiões Norte e Nordeste. Na regressão linear múltipla, a insegurança alimentar foi inversamente relacionada ao escore do PHDI (ꞵ = -0,56; IC95%: -1,06; -0,06), sendo as menores pontuações associadas à insegurança alimentar grave (β = -1,31; IC95%: -2,19; -0,55). As categorias de renda não foram independentemente associadas com o escore PHDI (p de tendência = 0,900). Portanto, a insegurança alimentar demonstrou afetar negativamente a adesão dos brasileiros à dieta planetária.

Resumen: El objetivo de este estudio fue investigar la relación entre la adherencia a la dieta planetaria con la situación de seguridad alimentaria y nutricional y el ingreso familiar per cápita en un estudio con una muestra representativa de la población brasileña. Entre los datos de la Encuesta de Presupuestos Familiares (POF) 2017-2018, los indicadores de desigualdad seleccionados para el análisis fueron la información sobre el ingreso familiar per cápita y la seguridad alimentaria y nutricional. También se utilizaron los datos de consumo alimentario individual de 46.164 brasileños ≥ 10 años, obtenidos mediante registros de alimentos de 24 horas, en la Encuesta Nacional Alimentaria, realizada con POF 2017-2018. Se utilizó el Índice de Dieta Planetaria (PHDI) para medir la adherencia a la dieta planetaria. Los datos sociodemográficos se expresaron como frecuencia (%), con análisis de la media e intervalo de 95% de confianza (IC95%) de la puntuación del PHDI. La relación entre el seguridad alimentaria y nutricional y los ingresos con la puntuación del PHDI se probó en modelos de regresión lineal múltiple. Los cálculos se realizaron en el software Stata, con el nivel de significación del 5%. Se observaron medias más bajas del PHDI entre individuos con inseguridad alimentaria, hombres, < 20 años, pardos e indígenas, con ingresos < 0,5 salario mínimo, residentes en zonas rurales y en las regiones Norte y Nordeste de Brasil. En la regresión lineal múltiple, la inseguridad alimentaria se relacionó inversamente con la puntuación del PHDI (ꞵ = -0,56; IC95%: -1,06; -0,06), y las puntuaciones más bajas estaban asociadas con la inseguridad alimentaria grave (β = -1,31; IC95%: -2,19; -0,55). Las categorías de ingresos no se asociaron de forma independiente con la puntuación PHDI (p de tendencia = 0,900). Por lo tanto, la inseguridad alimentaria afecta negativamente la adherencia de los brasileños a la dieta planetaria.

Abstract: This study aimed to investigate the relation of adherence to the planetary diet with food and nutrition security status and per capita household income in a study with a representative sample of the Brazilian population. Among the data from the 2017-2018 Brazilian Household Budgets Survey (POF), the inequality indicators selected for the analysis were data on per capita household income and food and nutrition security. We also considered data on the individual food consumption of 46,164 Brazilians aged ≥ 10 years, obtained through 24-hour dietary recalls, in the National Food Survey, conducted with the POF 2017-2018. The Planetary Health Diet Index (PHDI) was used to measure adherence to the planetary diet. Sociodemographic data were expressed as frequency (%), with analysis of the mean and 95% confidence interval (95%CI) of the PHDI score. The relation of food and nutrition security and income with the PHDI score was tested in multiple linear regression models. The calculations were performed in the Stata software, adopting a 5% significance. Lower PHDI means were observed among food insecure individuals, male, < 20 years old, mixed-race and indigenous, with income < 0.5 minimum wage, residing in rural areas and in the North and Northeast regions. In the multiple linear regression, food insecurity was inversely related to PHDI score (ꞵ = -0.56; 95%CI: -1.06; -0.06), with the lowest scores associated with severe food insecurity (β = -1.31; 95%CI: -2.19; -0.55). Income categories were not independently associated to PHDI score (p-trend = 0.900). Therefore, food insecurity has been shown to negatively affect Brazilians' adherence to the planetary diet.

Association between coffee consumption with serum lipid profile in ELSA-Brasil study: a metabolomic approach.

PURPOSE: This study evaluated the association between coffee consumption and serum lipid profile in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). METHODS: This is a cross-sectional study on baseline data from participants of the cohort ELSA-Brasil. Only participants of São Paulo Research Center who underwent a nuclear magnetic resonance (NMR) spectroscopy examination of lipid profile were included (N = 4736). Coffee intake was categorized into four categories (cups/day, in reference cup size of 50 mL, which is the household measure adopted in Brazil): never/almost never, ≤ 1, 1-3, and > 3. Serum lipid profile [i.e., Total Cholesterol (TC), Total Triglycerides (TG), Very Low-Density Lipoprotein-cholesterol (VLDL-c), Low-Density Lipoprotein-cholesterol (LDL-c), High-Density Lipoprotein-cholesterol (HDL-c), Triglyceride-rich Lipoprotein Particles (TRLP) and subfractions particles] was analyzed. To estimate the effect of coffee consumption on serum lipid profile, multivariate Generalized Linear Models were performed. RESULTS: Compared to participants who never or almost never drink coffee, individuals who consumed more than 3 cups/day showed an increase in concentrations of TC (ß: 4.13; 95% CI 0.81, 7.45), TG (ß: 9.53; 95% CI 1.65, 17.42), VLDL-c (ß: 1.90; 95% CI 0.38, 3.42), TRLP (ß: 8.42; 95% CI 1.24, 15.60), and Very Small-TRLP and Medium-TRLP subfractions (ß: 7.36; 95% CI 0.21, 14.51; ß: 2.53; 95% CI 0.89, 4.16, respectively), but not with HDL-c and LDL-c. Among individuals with low (≤ 1 cup/day) and moderate (1-3 cups/day) coffee consumption, no significant associations with lipids was observed. CONCLUSION: High coffee consumption (more than 3 cups per day) was associated with an increase in serum lipids, namely TC, TG, VLDL-c, and TRL particles, highlighting the importance of a moderate consumption of this beverage.

Folate and vitamin B12 status: temporal evaluation after mandatory fortification in Brazil.

OBJECTIVES: To perform temporal evaluation of folate and vitamin B12 status and their associated factors in a Brazilian population exposed to mandatory fortification. METHODS: Data from the cross-sectional population-based studies 2008 and 2015 Health Surveys of São Paulo, including individuals ≥ 20 years, both sexes, N = 549 in 2008 and N = 610 in 2015. Folate and vitamin B12 biomarkers status, B-complex supplements and medications use, and dietary intake were assessed. RESULTS: Serum folate concentrations increased in the entire population, adults and older adults in 2015 compared to 2008, while serum vitamin B12 concentration increased only in older adults. B-complex supplement use raised in 2015, reflecting in serum vitamins status. Overall serum vitamin B12 deficiencies (<200 pg/mL) were 23.2% and 21.2%, while serum folate deficiencies (<4 ng/mL) were 4.1% and 1.5% in 2008 and 2015, respectively. The lowest quintile of serum folate (≤8.7 ng/mL) was positively associated with smoking and oral contraceptive use, while the highest quintile (≥17.8 ng/mL) was inversely associated with smoking and positively with B-complex supplement use. The odds of having vitamin B12 deficiency was inversely associated with B-complex supplement use, higher serum folate median, higher dietary vitamin B12 intake and positively associated with using oral contraceptive. CONCLUSION: Overall deficiency of folate has decreased in 2015, being almost non-existent. Low vitamin B12 status presented similar proportions in the overall population comparing both periods, except for older adults. Different predictive variables were identified to better understand vitamins status outcomes in the most recent period of the study.

An index measuring adherence to New Zealand Infant Feeding Guidelines has convergent validity with maternal socio-demographic and health behaviours and with children's body size.

Using data from a nationally generalisable birth cohort, we aimed to: (i) describe the cohort's adherence to national evidence-based dietary guidelines using an Infant Feeding Index (IFI) and (ii) assess the IFI's convergent construct validity, by exploring associations with antenatal maternal socio-demographic and health behaviours and with child overweight/obesity and central adiposity at age 54 months. Data were from the Growing Up in New Zealand cohort (n 6343). The IFI scores ranged from zero to twelve points, with twelve representing full adherence to the guidelines. Overweight/obesity was defined by BMI-for-age (based on the WHO Growth Standards). Central adiposity was defined as waist-to-height ratio > 90th percentile. Associations were tested using multiple linear regression and Poisson regression with robust variance (risk ratios, 95 % CI). Mean IFI score was 8·2 (sd 2·1). Maternal characteristics explained 29·1 % of variation in the IFI score. Maternal age, education and smoking had the strongest independent relationships with IFI scores. Compared with children in the highest IFI tertile, girls in the lowest and middle tertiles were more likely to be overweight/obese (1·46, 1·03, 2·06 and 1·56, 1·09, 2·23, respectively) and boys in the lowest tertile were more likely to have central adiposity (1·53, 1·02, 2·30) at age 54 months. Most infants fell short of meeting national Infant Feeding Guidelines. The associations between IFI score and maternal characteristics, and children's overweight/obesity/central adiposity, were in the expected directions and confirm the IFI's convergent construct validity.

Prevalence of inadequate intake of folate in the post-fortification era: data from the Brazilian National Dietary Surveys 2008-2009 and 2017-2018.

The objectives were to compare the evolution of dietary folate intake, to estimate the prevalence of folate inadequacy (POFI) and the contribution of food groups to folate intake (dietary folate plus folic acid from fortified foods) in two post-fortification periods in the Brazilian population, according to life stages, geographic regions and per capita income. Population-based study including representative data from the National Dietary Survey - Brazilian Household Budget Surveys (NDS-HBS) 2008-2009 and 2017-2018, with a total of 32 749 (2008-2009) and 44 744 (2017-2018) individuals aged ≥ 10 years old, excluding pregnant and lactating women. The National Cancer Institute method was used to estimate the distributions of usual dietary folate intake. POFI was estimated according to estimated average requirement cut-off point method. After 10 years of the first NDS-HBS, POFI has increased in all sex-age groups, except for 10-13 years. POFI among women of reproductive age was around 30 and 40 % in 2008-2009 and 2017-2018. Higher POFI was observed in the North region. The top five food groups contributors to folate intake in Brazil were beans, breads, pasta and pizza, cakes and cookies and non-alcoholic beverages groups in both periods, differing in the rank order of the last two groups. Although being a country that has adopted mandatory folic acid flour fortification for almost two decades, increased POFI was observed in 2017-2018. This study brings significant scientific information, which can help understand folate dietary data in different contexts and consequently guide the approach for public health fortification strategies.

Estimation of underreporting of energy intake using different methods in a subsample of the ELSA-Brasil study / Estimativa da subnotificação de ingestão energética através de diferentes métodos em uma subamostra do estudo ELSA-Brasil / Estimación de la infradeclaración de la ingesta de energía utilizando diferentes métodos en una submuestra del estudio del ELSA-Brasil

Existing methods for assessing food consumption are subject to measurement errors, especially the underreporting of energy intake, characterized by reporting energy intake below the minimum necessary to maintain body weight. This study aimed to compare the identification of energy intake underreporters using different predictive equations and instruments to collect dietary data. The study was conducted with 101 selected participants in the third wave of the Longitudinal Study of Adult Health (ELSA-Brasil) at the University Hospital of the University of São Paulo. For the dietary assessment, we applied a food frequency questionnaire (FFQ), two 24-hour diet recall (24hR) using the GloboDiet software, and two 24hR using the Brasil-Nutri software. The energy intake underreport obtained from the FFQ was 13%, 16%, and 1% using the equations proposed by Goldberg et al. (1991), Black (2000), and McCrory et al. (2002), respectively. With these same equations, the 24hR described an underreport of 9.9%, 14.9%, and 0.9% respectively with the GloboDiet software and 14.7%, 15.8%, and 1.1% respectively with the Brasil-Nutri software. We verified a low prevalence of underreported energy intake among the three self-report-based dietary data collection methods (FFQ, 24hR with GloboDiet, and Brasil-Nutri). Though no statistically significant differences were found among three methods, the equations for each method differed among them. The agreement of energy intake between the methods was very similar, but the best was between GloboDiet and Brasil-Nutri.

Os métodos existentes para avaliar consumo alimentar estão sujeitos a erros de medição, especialmente à subnotificação de ingestão calórica, que descreve a ingestão calórica abaixo do mínimo necessário para manter o peso corporal. Este estudo buscou comparar a identificação de subnotificações de ingestão calórica através de diferentes equações preditivas e instrumentos para coletar dados dietéticos. Este estudo foi realizado com 101 participantes selecionados na terceira onda do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) do Hospital Universitário da Universidade de São Paulo. A partir da avaliação dietética, aplicamos um questionário de frequência alimentar (QFA), dois recordatórios de 24 horas (24hR) pelo software GloboDiet e dois 24hR utilizando o software Brasil-Nutri. A subnotificação de ingestão calórica obtida pelo QFA foi de 13%, 16% e 1%, utilizando-se as equações propostas por Goldberg et al. (1991), Black (2000) e McCrory et al. (2002), respectivamente. Com essas mesmas equações, o 24hR achou uma subnotificação de 9,9%, 14,9% e 0,9%, respectivamente, com o software GloboDiet e de 14,7%, 15,8% e 1,1%, respectivamente, com o software Brasil-Nutri. Verificou-se baixa prevalência de ingestão calórica subnotificada entre os três métodos de captação de dados dietéticos por autorrelato (FFQ e 24hR com GloboDiet e Brasil-Nutri). As equações para cada método diferem entre si embora não tenhamos encontrado diferenças estatisticamente significativas entre os três métodos. A concordância de ingestão calórica entre os métodos foi muito semelhante, mas a melhor foi entre a GloboDiet e a Brasil-Nutri.

Los métodos existentes para evaluar el consumo de alimentos están sujetos a errores de medición, especialmente la infradeclaración de la ingesta de energía, caracterizada por la notificación de la ingesta de energía por debajo del mínimo necesario para mantener el peso corporal. El objetivo de este estudio era comparar la identificación de las infradeclaraciones de ingesta energética utilizando diferentes ecuaciones de predicción e instrumentos de recogida de datos dietéticos. El estudio se realizó con 101 participantes seleccionados en la tercera ola del Estudio Longitudinal de Salud del Adulto (ELSA-Brasil) en el Hospital Universitario de la Universidad de São Paulo. Para la evaluación de la dieta, se aplicó un cuestionario de frecuencia de alimentos (QFA), dos recordatorios de dieta de 24 horas (24hR) utilizando el software GloboDiet, y dos 24hR utilizando el software Brasil-Nutri. La infradeclaración de la ingesta energética obtenida del QFA fue del 13%, el 16% y el 1,0% utilizando las ecuaciones propuestas por Goldberg et al. (1991), Black (2000) y McCrory et al. (2002), respectivamente. Con estas mismas ecuaciones, el 24hR describió una infradeclaración del 9,9%, el 14,9% y el 0,9% respectivamente con el software GloboDiet y del 14,7%, el 15,8% y el 1,1% respectivamente con el software Brasil-Nutri. Se verificó una baja prevalencia de ingesta de energía subdeclarada entre los tres métodos de recogida de datos dietéticos basados en el autoinforme (QFA, 24hR con GloboDiet y Brasil-Nutri). Aunque no se encontraron diferencias estadísticamente significativas entre los tres métodos, las ecuaciones de cada uno de ellos diferían entre sí. La concordancia de la ingesta de energía entre los métodos fue muy similar, pero la mejor fue entre GloboDiet y Brasil-Nutri.

Proposta metodológica para avaliação da insegurança alimentar sob a ótica de suas múltiplas dimensões / A methodological proposal for assessing food insecurity from a multidimensional perspective

Resumo O objetivo deste artigo é desenvolver uma proposta metodológica para avaliar a insegurança alimentar e nutricional (INSAN) em adultos e idosos. A proposta metodológica Vigi-INSAN foi elaborada com dados do Brazuca Natal, um estudo transversal com 411 residentes de Natal-RN. O modelo preditivo foi desenvolvido por regressão múltipla de Poisson, analisando-se as variáveis sociodemográficas, de saúde e nutrição, e a insegurança alimentar (IA). A prevalência de IA foi 42,1% (37,4%-46,9%), sendo maior em mulheres (47,5%), adultos (48,2%) e pessoas de cor/raça preta (52,7%). O Vigi-INSAN foi composto por: presença de <18 anos no domicílio (A) (RPaj=1,3; 1,1-1,6), renda familiar (B) (em quintis) (Q1: RPaj=5,4; 2,5-11,7; Q2: RPaj=4,8; 2,2-10,5; Q3: RPaj=3,8; 1,8-8,5; Q4 RPaj=2,2; 1,0-5,1), tratamento inadequado da água de beber (C) (RPaj=1,3; 1,1-1,5), presença de DCNT (D) (RPaj=1,3; 1,1-1,7), não comer frutas no café da manhã (E) (RPaj=1,7; 1,3-2,5), realizar refeições no sofá da sala ou na cama (F) (RPaj=1,3; 1,1-1,6) e pular pelo menos o almoço ou o jantar (G) (RPaj=1,4; 1,2-1,7). Foi adotado o ponto de corte 2,3 (Kappa=0,47; Sensibilidade=0,82; Especificidade=0,67; VPP=0,64; VPN=0,83).

Abstract The aim of this study was to develop a methodological proposal for the assessment of food and nutritional insecurity (FNiS) in adults and older adults (Vigi-FNiS). The proposal was developed using data from the BRAZUCA Natal survey, a cross-sectional study with 411 people living in Natal in the state of Rio Grande do Norte, Brazil. The association between sociodemographic, health and nutrition variables and food insecurity (FI) was tested using Poisson multiple regression. Overall prevalence of FI was 42.1% (37.4%-46.9%) and was higher in women (47.5%), adults (48.2%) and black people (52.7%). The following variables were included in the Vigi-FNiS: people aged <18 years living in the household (A) (AdjPR=1.3; 1.1-1.6); family income (B) in quintiles (Q1: AdjPR=5, 4; 2.5-11.7; Q2: AdjPR=4.8; 2.2-10.5; Q3: AdjPR=3.8; 1.8-8.5; Q4 AdjPR=2.2; 1.0-5.1); inadequate treatment of drinking water (C) (AdjPR=1.3; 1.1-1.5); presence of chronic non-communicable diseases (D) (AdjPR=1.3; 1.1-1.7); not eating fruit for breakfast (E) (AdjPR=1.7; 1.3-2.5);eating meals on the couch or in bed (F) (AdjPR=1.3; 1.1-1.6); and skipping either lunch or dinner or dinner (G) (AdjPR=1.4; 1.2-1.7). A cutoff point for FNiS of 2.3 was adopted (Kappa=0.47; sensitivity=0.82; specificity=0.67; PPV=0.64; NPV=0.83).

O papel do Sistema Único de Saúde no combate à sindemia global e no desenvolvimento de sistemas alimentares sustentáveis / The role of the Brazilian Unified Health System in combating the global syndemic and in the development sustainable food systems

Resumo As pandemias de desnutrição e obesidade, em conjunto com as mudanças climáticas, constituem uma sindemia global e apresentam um importante ponto de convergência, que é a insustentabilidade dos sistemas alimentares atuais. O objetivo deste artigo é discutir o papel de políticas públicas de saúde, particularmente do Sistema Único de Saúde (SUS) no âmbito da Atenção Primária à Saúde, no combate à sindemia global e no desenvolvimento de sistemas alimentares sustentáveis. Nesse contexto, a Política Nacional de Alimentação e Nutrição se destaca como uma importante ferramenta intersetorial para a alimentação adequada e saudável e à segurança alimentar e nutricional. Além disso, o Guia Alimentar se apresenta como um instrumento estratégico de apoio às ações de educação alimentar e nutricional. De modo essencial, destaca-se a necessidade de articulação das políticas de saúde, agricultura e meio ambiente para que o desenvolvimento sustentável possa ser efetivado. Assim, o SUS tem capacidade de ser palco das principais discussões sobre essa temática, atuando como um potencializador de ações individuais, coletivas e institucionais para promover um sistema alimentar mais justo, saudável e sustentável.

Abstract The undernutrition and obesity pandemics associated with climate change are a global syndemic. They have a point of convergence, which is the unsustainable current food systems. This paper aims to discuss the role of public health policies, particularly the Brazilian Unified Health System (SUS) in the context of Primary Health Care, in combating the global syndemic and in the development of sustainable food systems. In this scenario, the National Food and Nutrition Policy is a leading intersectoral tool for an adequate and healthy diet and food and nutrition security. Also, the Dietary Guidelines for the Brazilian population is a strategic tool to support food and nutrition education. We highlight the need to articulate health, agriculture, and environmental policies to achieve sustainable development. Thus, SUS can be the arena to promote the main discussions on this topic, potentiating individual, group, and institutional actions to provide a fairer, healthy, and sustainable food system.

Dietary patterns among adolescents and associated factors: longitudinal study on sedentary behavior, physical activity, diet and adolescent health. / Padrões alimentares de adolescentes e fatores associados: estudo longitudinal sobre comportamento sedentário, atividade física, alimentação e saúde dos adolescentes.

The aim of the present study was to identify dietary patterns and associations with socioeconomic characteristics, lifestyle, nutritional status, lipid profile and inflammatory profile in adolescents. A cross-sectional study was conducted with a probabilistic sample using baseline data (2014) from the Longitudinal Study on Sedentary Behavior, Physical Activity, Eating Habits and Adolescent Health. A total of 1,438 adolescents (10 to 14 years old) from public schools in the city of João Pessoa, Brazil, participated in the study. Data were collected on socioeconomic characteristics, nutritional status, lifestyle and the results of biochemical tests. Dietary data were obtained using the 24-hour recall method and dietary patterns were identified by exploratory factor analysis. Associations of interest were estimated using multiple logistic regression. Three dietary patterns were found: "Traditional", "Snacks" and "Western". These patterns were associated with age, socioeconomic status, parental education and lifestyle. The "Traditional" pattern was associated lower adiposity and a better lipid profile. However, with the increase in age, greater frequencies of the "Snacks" and "Western" patterns were found. The present findings underscore the need for strategies that encourage healthy behaviors.

Objetivou-se identificar padrões alimentares e sua associação com características socioeconômicas, de estilo de vida, estado nutricional, perfil lipídico e inflamatório em adolescentes. Estudo transversal, com amostra probabilística, utilizando dados da linha de base (2014) do Estudo Longitudinal sobre Comportamento Sedentário, Atividade Física, Hábitos Alimentares e Saúde de Adolescentes (LONCAAFS). Participaram 1.438 adolescentes (10 a 14 anos), da rede pública de João Pessoa-PB. Foram obtidos dados socioeconômicos, medidas antropométricas, estilo de vida e exames bioquímicos. Os dados dietéticos foram obtidos por recordatórios de 24h, sendo os padrões alimentares identificados por análise fatorial exploratória e as associações de interesse estimadas por regressão logística múltipla. Foram encontrados três padrões alimentares: "Tradicional", "Lanches" e "Ocidental" que se associaram com idade, nível socioeconômico, escolaridade dos pais e estilo de vida. O padrão "Tradicional" se mostrou associado a menor adiposidade e melhor perfil lipídico, porém com a maior idade, há maior adesão aos padrões "Lanches" e "Ocidental". Os resultados da análise do padrão alimentar de adolescentes apontam para necessidade de estratégias que incentivem comportamentos saudáveis.

Moderate coffee consumption is associated with lower risk of mortality in prior Acute Coronary Syndrome patients: a prospective analysis in the ERICO cohort.

This study examined the association between coffee consumption and all-cause mortality in patients with a prior acute myocardial infarction or unstable angina. Data were from the prospective study ERICO, totalising 928 patients with Acute Coronary Syndrome (ACS). During 4 years' follow-up, a total of 111 deaths occurred. Moderate coffee consumption (1-2 and 2-3 cups/day) was inversely associated with total mortality (HR 0.13, 95% CI: 0.06-0.29 and 0.22, 95% CI: 0.13-0.39, respectively). For patients with higher coffee consumption (>3 cups/day), there was a positive association with mortality (HR 2.12, 95% CI: 1.06-4.24). After stratification by smoking status, the analysis revealed lower risk of mortality in never and former smokers, drinking 1-2 and 2-3 cups/day. Among current smokers there was a positive association between >3 cups/day and mortality. The moderate consumption of coffee was associated with lower risk of all-cause mortality in patients with a prior ACS, particularly in non-smokers.

Plasma metabolomics are associated with metabolic syndrome: A targeted approach.

OBJECTIVES: Advances in metabolomic tools have allowed us to gain a more comprehensive understanding of metabolic syndrome (MetS). The aim of this study was to evaluate the association between plasma metabolomic profiles and MetS. METHODS: For this study, adults without diabetes, chronic kidney disease, stroke, heart disease, or cancer and with full metabolomics, biochemical, and dietetic data available, representing a subsample of the Health Survey of Sao Paulo study (ISA-Capital; N = 130), were included. The joint interim statement consensus criteria were used for diagnosing MetS. Absolute quantification (µmol/L) of blood metabolites was achieved by targeted quantitative profiling of annotated metabolites by electrospray ionization tandem mass spectrometry in plasma samples. Mean differences in the compounds for MetS were evaluated by linear regression adjusted for confounding factors. RESULTS: Serine was inversely associated with MetS (ß = -15.04; P = 0.014). In glycerophospholipids with acyl-alkyl bonds, there was an inverse association with MetS, including phosphatidylcholine (PC) ae C42:5 (ß = -0.15; P = 0.040), PC ae C44:5 (ß = -0.15; P = 0.046), PC ae C40:4 (ß = -0.21; P = 0.014) and PC ae C44:4 (ß = -0.04; P = 0.032). CONCLUSION: Plasma metabolomic profiles were associated with MetS, especially the amino acid serine and some acyl-alkyl PCs.

Ingestion of magnesium was not associated with coronary calcium score in a cross-sectional study.

Background and aims: Magnesium plays a key role in glucose metabolism, vascular tone, and inflammation. Therefore, it might be a dietary risk factor for cardiovascular diseases. In vitro and animal studies have suggested a decrease in vascular calcification with an increase in the magnesium intake. The objective of the present study was to investigate the association between magnesium intake and coronary artery calcium (CAC) score among participants of the ELSA-Brasil. Methods: This is an observational, cross-sectional study undertaken with a sub-sample from the ELSA-Brasil baseline data. In this sub-sample, only participants with CAC examination data were included (n = 4,306). Dietary intake was assessed by a validated food frequency questionnaire. The association between magnesium intake and presence of CAC (0 versus > 0) was investigated using multiple logistic regression models. Results: The participants were predominantly female (54.4 %), with self-reported white skin color (59.1 %), no smoking habit (53.7 %) and undergraduate or postgraduate education (44.4 %). The range of magnesium consumption was 37.24 - 1266.31 mg/day. CAC prevalence was 28.4 %. No significant association was found between magnesium intake and CAC after adjustments for diet, lifestyle, and clinical characteristics. In a first univariate model, the fifth quintile of magnesium intake, in comparison to the first quintile (lowest intake), resulted in an OR = 1.25, 95 % CI: 1.01 - 1.54 (P-linear trend = 0.005). However, in the last fully adjusted model, the fifth quintile of magnesium intake resulted in OR = 0.86, 95 % CI: 0.64 - 1.17 (P-linear trend = 0.239). Conclusions: In ELSA-Brasil, the intake of magnesium was not associated with the presence of coronary artery calcification.

Unmetabolized folic acid is associated with TNF-α, IL-1ß and IL-12 concentrations in a population exposed to mandatory food fortification with folic acid: a cross-sectional population-based study in Sao Paulo, Brazil.

PURPOSE: The study assessed associations between inflammatory markers, as cytokines, adhesion molecules and unmetabolized folic acid (UMFA) among a population exposed to mandatory fortification. METHODS: Data were collected from a cross-sectional population-based survey (n = 302) conducted in São Paulo City, Brazil. UMFA was assayed by a modified affinity-HPLC method with electrochemical detection to measure the different forms of the folate in plasma. We used a commercial test kit to analyze cytokines and adhesion molecules. Multiple logistic regressions were applied to investigate the association between inflammatory markers and UMFA. Multiple models were adjusted for sex, age, self-reported skin color, BMI and smoking status. RESULTS: The prevalence of detectable UMFA in this population was high (81.2%), with median concentration of 1.67 nmol/L. The odds ratios (95% CIs) for having higher immunological markers levels among individuals in the highest tertile of UMFA were 0.44 (0.24; 0.81) for TNF-α, 0.92 (0.49; 1.75) for CRP, 1.32 (0.70; 2.48) for ICAM, 0.99 (0.54; 1.81) for VCAM, 0.45 (0.25; 0.83) for IL-1ß, 0.74 (0.40; 1.38) for IL-6, 1.34 (0.73; 2.44) for IL-8, 0.65 (0.36; 1.18) for IL-10 and 0.49 (0.27; 0.89) for IL-12. CONCLUSION: UMFA concentrations were inversely associated with elevated proinflammatory markers (TNF-α, IL-1ß and IL-12). These results signalize a link between folate metabolism and the inflammatory status of adults in an apparently folate-replete population.

Coffee consumption and risk of hypertension: A prospective analysis in the cohort study.

BACKGROUND: Coffee is one of the most widely consumed beverages around the world. Dietary habits, specifically, coffee consumption has long been a suspected cause of hypertension. However, previous findings on coffee consumption and its association with the incidence of hypertension are not homogeneous and still inconsistent. PURPOSE: To examine the association of habitual coffee consumption with the risk of developing hypertension in a middle-aged Brazilian cohort. METHODS: Data were from the multicenter prospective cohort "Brazilian Longitudinal Study for Adult Health - ELSA-Brasil". The cohort comprises 15,105 civil servants, aged 35-74 years at baseline, who were sampled from universities located in six Brazilian cities. For the present study, we analyzed data from 8780 participants initially free of hypertension during a mean follow-up of 3.9 years. The consumption of coffee was obtained at baseline using a previously validated semi-quantitative food frequency questionnaire (FFQ). Subsequently coffee intake was categorized into four categories (cups/day): never/almost never, ≤1, 1-3, and >3. Hypertension status was defined as a systolic blood pressure ≥140 mmHg or a diastolic blood pressure ≥90 mmHg, use of antihypertensive drug treatment, or both. Poisson regression model with a robust variance was performed to estimate relative risk (RR) and confidence interval (95% CI) for hypertension according to baseline coffee consumption. The effect of interaction between coffee consumption and smoking status was assessed. RESULTS: Most participants (90%) drank coffee, and the median total coffee intake was 150 mL/day. A total of 1285 participants developed hypertension. Compared to participants who never or almost never drink coffee, the risk of hypertension was lower for individuals consuming 1-3 cups/day (RR 0.82, 95% CI: 0.68-0.97) (P for interaction=0.018). After stratification by smoking status the analysis revealed a decreased risk of hypertension in never smokers drinking 1-3 cups of coffee per day (RR 0.79, 95% CI: 0.64-0.98), whereas the hypertension risk among former and current smokers was not associated with coffee consumption significantly. Moreover, upper category of coffee drinking (>3 cups/day) the association was not significant for risk of hypertension. CONCLUSION: The association between coffee consumption and incidence of hypertension was related to smoking status. The beneficial effect of moderate coffee intake (1-3 cups/day) on risk of hypertension was observed only in never smokers.

Limitations in the comparison of the Brazilian National Dietary Surveys of 2008-2009 and 2017-2018 / Limitações na comparação dos Inquéritos Nacionais de Alimentação de 2008-2009 e 2017-2018

ABSTRACT OBJETIVE: To present particular characteristics of two Brazilian National Dietary Surveys (Inquéritos Nacionais de Alimentação - INA) and the methodology used to better compare their data. METHODS: This study details the differences between both INA conducted by the Brazilian Institute of Geography and Statistics (IBGE) in 2008-2009 and 2017-2018. We present the alterations in data collecting methods and food composition tables as well as the analysis strategies recommended to obtain such data. A validation study with 95 participants of the third wave of the Longitudinal Study of Adult Health assessed the measurement error associated with the procedures adopted in the 24-hours dietary recall of INA 2017-2018. The reference standards were urinary protein recovery, sodium, and potassium biomarkers. Different strategies were used in the analysis of INA to compare two essential dietary items that had their collection method changed: fats and sugars. RESULTS: The validation study indicated lower underreport in the most recent survey with higher means of energy intake. The correlation of means for the 24-hours recalls with their respective biomarkers was 0.58 for proteins, 0.31 for potassium, and 0.30 for sodium. Comparing the food composition tables used in both surveys with the data obtained by INA 2008-2009, the mean variation of energy, macronutrients, and minerals was lower than 15%, except for trans fats and selenium, which had means 40% and 52% lower in the Tabela Brasileira de Composição de Alimentos (TBCA - Brazilian Food Composition Table). INA 2017-2018 presents lower means for added sugar, using a generic question about the frequency of sugar consumption as a measure for sugar as an additional item. CONCLUSION: The methodological changes promoted in the most recent INA enhanced food groups and nutrients intake estimation, adding detailed and specific data in dietary habits reports.

RESUMO OBJETIVO: Apresentar particularidades dos dois Inquéritos Nacionais de Alimentação (INA) e o processo metodológico empregado para comparação dos dados. MÉTODOS: O estudo detalha as diferenças entre os INA realizados pelo IBGE em 2008-2009 e em 2017-2018, apresentando as alterações nos métodos de coleta de dados e nas tabelas de composição dos alimentos, assim como as estratégias de análise recomendadas para comparação dos dados. Um estudo de validação foi realizado com 95 participantes da terceira onda do Estudo Longitudinal de Saúde do Adulto a fim de avaliar o erro de medição associado aos procedimentos adotados nos recordatórios de 24 horas do INA 2017-2018. Empregaram-se biomarcadores de recuperação urinária de proteínas, sódio e potássio como padrões de referência. Na análise dos INA, diferentes estratégias foram elaboradas para comparar dois itens importantes do consumo alimentar que sofreram mudanças na forma de coleta: as gorduras e os açúcares. RESULTADOS: O estudo de validação do instrumento indicou menor sub-relato no inquérito mais recente, com maiores médias de ingestão de energia. A correlação das medidas dos recordatórios de 24 horas com os respectivos biomarcadores foi de 0,58 para proteínas, 0,31 para potássio e 0,30 para sódio. Comparando as tabelas de composição utilizadas nos dois inquéritos com os dados obtidos no INA 2008-2009, a variação média de energia, macronutrientes e minerais foi menor que 15%, com exceção das gorduras trans e selênio, com médias 40% e 52% menores na TBCA. No INA 2017-2018, as médias do consumo de açúcar de adição foram menores, usando a informação do açúcar reportado como item de adição comparada com a pergunta genérica sobre a frequência do uso do açúcar. CONCLUSÃO: As mudanças metodológicas incluídas no INA atual permitiram aprimorar as estimativas de consumo de grupos de alimentos e nutrientes, acrescentando informações mais detalhadas e específicas aos relatos do consumo alimentar.

Dietary patterns of Brazilian adults in 2008-2009 and 2017-2018 / Padrões alimentares de adultos brasileiros em 2008-2009 e 2017-2018

ABSTRACT OBJECTIVES To identify dietary patterns among Brazilian adults based on the National Dietary Surveys (INA - Inquéritos Nacionais de Alimentação) in 2008-2009 and 2017-2018, and to verify in the second period the adherence to the patterns according to sociodemographic factors and Brazilian regions. METHODS We analyzed the first of two days of adults' food consumption (19-59 years) in INA data from 2008-2009 (n = 21,630) and 2017-2018 (n = 28,901). Dietary patterns were derived by exploratory factor analysis from 19 food groups, considering the complexity of the sample design. We evaluated the factor scores according to sex, age group, region, per capita income, and education for the INA data in 2017-2018. RESULTS We identified three patterns in the two surveys: (1) "traditional", characterized by rice, beans, and meat; (2) "breads and butter/margarine", characterized by breads, oils, and fats (including margarine/butter) and, coffee and teas in 2008-2009; and (3) "western", characterized by sodas, pizzas, snacks, flour, pasta, and sweets in 2017-2018. The "traditional" pattern had greater adherence among men, residents of the Midwest region and individuals with incomplete primary education. "Bread and butter/margarine" pattern had greater adherence among males, individuals aged between 40 and 59 years, from the Southeast region, and with income between 1 and 2 minimum wages per capita. Male individuals, aged between 19 and 39 years, from the South region, with per capita income greater than two minimum wages, and education level equal to or greater than primary education showed greater adherence to the "western" pattern. CONCLUSION The dietary patterns identified in 2008-2009 and 2017-2018 were similar, and we observed the maintenance of the "traditional" pattern, which includes rice, beans, and meat. Adherence to the dietary patterns varies according to sex, age group, region, per capita income, and education level.

RESUMO OBJETIVOS Identificar padrões alimentares entre adultos brasileiros a partir dos Inquéritos Nacionais de Alimentação (INA) 2008-2009 e 2017-2018, verificando, nesse último período, a aderência aos padrões de acordo com fatores sociodemográficos e regiões brasileiras. MÉTODOS Foram analisados dados do primeiro de dois dias de consumo alimentar de adultos (19-59 anos de idade) entrevistados nos INA 2008-2009 (n = 21.630) e 2017-2018 (n = 28.901). Os padrões alimentares foram derivados por análise fatorial exploratória a partir de 19 grupos de alimentos, considerando a complexidade do desenho amostral. Para o INA 2017-2018, os escores fatoriais foram avaliados de acordo com sexo, faixa etária, região, renda per capita e escolaridade. RESULTADOS Foram identificados três padrões nos dois inquéritos: (1) "tradicional", caracterizado por arroz, feijão e carnes; (2) "pães e manteiga/margarina", caracterizado por pães, óleos e gorduras (incluindo margarina/manteiga) e, em 2008-2009, café e chás; e (3) "ocidental", caracterizado por refrigerantes e pizzas e salgados, além de farinhas e massas e doces em 2017-2018. O padrão "tradicional" teve maior aderência entre homens, moradores da região Centro-Oeste e indivíduos com ensino fundamental incompleto. Para o padrão "pães e manteiga/margarina", observou-se maior aderência entre o sexo masculino, indivíduos com idade entre 40 e 59 anos, da região Sudeste e com renda entre 1 e 2 salários-mínimos per capita. Indivíduos do sexo masculino, com idades entre 19 e 39 anos, da região Sul, com renda per capita maior que dois salários-mínimos e escolaridade igual ou maior que o ensino fundamental foram os que apresentaram maior adesão ao padrão "ocidental". CONCLUSÃO Os padrões alimentares identificados em 2008-2009 e 2017-2018 foram similares, com manutenção do padrão "tradicional", que inclui arroz, feijão e carnes. A adesão aos padrões varia de acordo com sexo, faixa etária, região, renda per capita e escolaridade.
