Dietary choline intake in European and non-european populations: current status and future trends-a narrative review.

BACKGROUND: Choline is a nutrient necessary for the proper functioning of the body with a multidimensional impact on human health. However, comprehensive studies evaluating the dietary intake of choline are limited. The aim of this narrative review is to analyze current trends in choline intake in European and non-European populations. The secondary aim was to discuss possible future choline trends. METHODS: The search strategy involved a systematic approach to identifying relevant literature that met specific inclusion criteria. Observational studies and randomized clinical trials were searched for in PubMed and Scopus databases from January 2016 to April 2024. This review includes the characteristics of study groups, sample sizes, methods used to assess choline intake and time period, databases used to determine intake, choline intakes, and the main sources of choline in the diet. The review considered all population groups for which information on choline intake was collected. RESULTS: In most studies performed in Europe after 2015 choline intake did not exceed 80% of the AI standard value. The mean choline intake for adults in different European countries were 310 mg/day, while the highest value was reported for Polish men at 519 mg/day. In non-European countries, mean choline intakes were 293 mg/day and above. The main reported sources of choline in the diet are products of animal origin, mainly eggs and meat. The available data describing the potential intake of these products in the EU in the future predict an increase in egg intake by another 8% compared to 2008-2019 and a decrease in meat intake by about 2 kg per capita from 2018 to 2030. CONCLUSIONS: In the last decade, choline intake among adults has been insufficient, both in Europe and outside it. In each population group, including pregnant women, choline intake has been lower than recommended. Future choline intake may depend on trends in meat and egg consumption, but also on the rapidly growing market of plant-based products. However, the possible changes in the intake of the main sources of choline may lead to either no change or a slight increase in overall choline intake.

Trends in the contribution of greenhouse gas emissions from food and beverage purchases in Mexico: 1989-2020.

BACKGROUND: Assessing the trends in dietary GHGE considering the social patterning is critical for understanding the role that food systems have played and will play in global emissions in countries of the global south. Our aim is to describe dietary greenhouse gas emissions (GHGE) trends (overall and by food group) using data from household food purchase surveys from 1989 to 2020 in Mexico, overall and by education levels and urbanicity. METHODS: We used cross-sectional data from 16 rounds of Mexico's National Income and Expenditure Survey, a nationally representative survey. The sample size ranged from 11,051 in 1989 to 88,398 in 2020. We estimated the mean total GHGE per adult-equivalent per day (kg CO2-eq/ad-eq/d) for every survey year. Then, we estimated the relative GHGE contribution by food group for each household. These same analyses were conducted stratifying by education and urbanicity. RESULTS: The mean total GHGE increased from 3.70 (95%CI: 3.57, 3.82) to 4.90 (95% CI 4.62, 5.18) kg CO2-eq/ad-eq/d between 1989 and 2014 and stayed stable between 4.63 (95% CI: 4.53, 4.72) and 4.89 (95% CI: 4.81, 4.96) kg CO2-eq/ad-eq/d from 2016 onwards. In 1989, beef (19.89%, 95% CI: 19.18, 20.59), dairy (16.87%, 95% CI: 16.30, 17.42)), corn (9.61%, 95% CI: 9.00, 10.22), legumes (7.03%, 95% CI: 6.59, 7.46), and beverages (6.99%, 95% CI: 6.66, 7.32) had the highest relative contribution to food GHGE; by 2020, beef was the top contributor (17.68%, 95%CI: 17.46, 17.89) followed by fast food (14.17%, 95% CI: 13.90, 14.43), dairy (11.21%, 95%CI: 11.06, 11.36), beverages (10.09%, 95%CI: 9.94, 10.23), and chicken (10.04%, 95%CI: 9.90, 10.17). Households with higher education levels and those in more urbanized areas contributed more to dietary GHGE across the full period. However, households with lower education levels and those in rural areas had the highest increase in these emissions from 1989 to 2020. CONCLUSIONS: Our results provide insights into the food groups in which the 2023 Mexican Dietary Guidelines may require to focus on improving human and planetary health.

National trends in nine key minerals intake (quantity and source) among U.S. adults, 1999 to march 2020.

BACKGROUND: Changes in economy and dietary guidelines brought a great shock to diet quality and meal behaviors, but if these transformations have extended to minerals intake and their sources was still poorly understood. It is essential to evaluate time trends in minerals intake and their sources to inform policy makers. OBJECTIVE: To investigate trends in minerals intake and their sources among U.S. adults. METHODS: This analysis used dietary data collected by 24-h recalls from U.S. adults (≥ 20 years) in NHANES (1999-March 2020). Minerals intake, age-adjusted percentage of participants meeting recommendations, and minerals sources were calculated among all participants and by population subgroups in each NHANES survey cycle. Weighted linear or logistic regression models were used to examine the statistical significance of time trends. RESULTS: A total of 48223 U.S. adults were included in this analysis. From 1999 to March 2020, intake of calcium (from 0.94 to 1.02 g/day), magnesium (from 308.07 to 321.85 mg/day), phosphorus (from 1.24 to 1.30 g/day), and sodium (from 3.24 to 3.26 mg/day) from food and beverages (FB) and dietary supplements (DSs) significantly increased, and intake of iron (from 19.17 to 16.38 mg/day), zinc (from 16.45 to 14.19 mg/day), copper (from 1.79 to 1.38 mg/day), and potassium (from 2.65 to 2.50 g/day) from FB + DSs decreased (all FDR < 0.05). Additionally, age-adjusted percentage of participants meeting recommendations for calcium, phosphorus, sodium, and selenium significantly increased, that for iron, potassium, zinc, and copper decreased (all FDR < 0.05). Minerals intake and time trends in minerals intake were highly variable depending on age, gender, race/ethnicity, education, and income. For example, white, higher socioeconomic status participants had a higher minerals intake (e.g. iron, zinc, and copper), but had a greater decrease in minerals intake. Furthermore, the percentage of minerals from milks and DSs decreased, and that from beverages increased. CONCLUSION: From 1999 to March 2020, both minerals intake and their sources experienced a significant alteration among U.S. adults. Many differences in minerals intake and their food sources across sociodemographic characteristics appeared to narrow over time. Although some improvements were observed, important challenges, such as overconsumption of sodium and underconsumption of potassium, calcium, and magnesium, still remained among U.S. adults.

[Change of dietary pattern among young people aged 18-35 in China from 1989 to 2018].

OBJECTIVE: To analyze the dietary patterns changes of young people aged 18-35 in 15 provinces(autonomous regions, municipalities) from 1989 to 2018. METHODS: Using the data of China Health and Nutrition Survey, a total of 25 400 young people aged 18-35 with complete dietary and sociodemographic information from 1989 to 2018 in 15 provinces(autonomous regions, municipalities) were selected as the research objects. Nutrition survey was carried out by using 3 consecutive days of 24-hour review method combined with weighing accounting method. Energy and nutrient intake was calculated based on food composition list. The principal component cluster analysis was used to select food groups and K-mean cluster was uesd to extract dietary patterns. Dwass-Steel-Critchlow-Fligner was used to test the difference of food intake in different dietary patterns. Cochran-Armitage trend test was to analyze the change of dietary patterns with the years. Chi-square test was to analyze the difference of people with different dietary patterns in 2018. RESULTS: The dietary patterns of young people aged 18-35 in 15 provinces(autonomous regions, municipalities) were mainly divided into three categories: "traditional rice", "traditional pasta" and "high-quality protein". In 2018, the proportion of "traditional rice" dietary patterns was higher for men than for women, and the proportion of "high-quality protein" dietary patterns was lower than for women. The proportion of "traditional pasta" dietary pattern in people aged 25-35 was higher than that aged 18-24, and the proportion of "high-quality protein" dietary pattern was lower than that aged 18-24. The proportion of people in urban with "traditional rice" dietary pattern was lower than that in rural areas, and the proportion of "high-quality protein" dietary pattern was higher than that in rural areas. The northern region was dominated by "traditional pasta" dietary pattern, while the southern region was dominated by "traditional rice" dietary pattern, and the proportion of people with "high-quality protein" dietary pattern was higher in the northern region than in the southern region. With the increase of education level and income level, the proportion of people with "high-quality protein" dietary pattern showed an increasing trend. From 1989 to 2018, the "traditional rice" dietary pattern had always maintained a high proportion among young people aged 18-35 in 15 provinces(autonomous regions, municipalities) in China, and the "traditional pasta" dietary pattern had been decreasing since 2009, and the "high-quality protein" dietary pattern had significantly increased since 2011. CONCLUSION: From 1989 to 2018, the proportion of young people aged 18-35 with reasonable dietary pattern has increased in 15 provinces(autonomous regions, municipalities), but the traditional dietary pattern still needs to be improved.

[Consumption status and growth trends of dairy products among children and adolescents in China from 1991 to 2018].

OBJECTIVE: To explore the dairy consumption among children and adolescents aged 7-17 in China. METHODS: 10 rounds of follow-up data from the "China Health and Nutrition Survey" from 1991 to 2018 were collected, and individuals aged 7-17 were selected as the study subjects. Dietary data was collected by using 3-day 24-hour dietary review method and household weighing accounting method(edible oils and seasonings). Dairy consumption was calculated by converting various dairy products into liquid milk intake using the China Food Composition. After excluding those with missing demographic information, missing data from the "3 days and 24 hours" dietary survey, and abnormal daily energy intake, 18 529 participants were included in the final analysis. Joinpoint regression model was used to analyze the trend of changes in dairy intake. RESULTS: The dairy consumption rate increased from 2.8% in 1991 to 42.3% in 2018, while it increased from 8.4% to 58.8% in urban and from 0.9% to 32.1% in rural areas. Meanwhile, the proportion of people whose dairy intake reaches the recommended intake(300 g/d) increased from 0.2% to 3.0%, and the proportion in rural area was 2.0%, which was lower than that in urban areas(4.9%). From 1991 to 2018, dairy intake increased at a rate of 12.97%(P=0.02), and the growth rate of urban and rural areas were 9.79%(P=0.03) and 15.67%(P<0.01), respectively. There was a faster growth trend from 1991-2004 compared to 2004-2018. The growth rate in urban and rural areas also showed different growth trends. CONCLUSION: The dairy intake of children and adolescents aged 7-17 in China improved significantly from 1991 to 2018, with higher consumption rate in urban areas than in rural areas, but it still need to be improved for health.

Mapping global research trends: Nutrition associations with nonalcoholic fatty liver disease - a Scopus bibliometric analysis.

BACKGROUND: Several bibliometric analyses have been carried out to identify research hotspots and trends in nonalcoholic fatty liver disease (NAFLD) research. Nonetheless, there are still significant knowledge gaps that must be filled to advance our understanding of and ability to treat NAFLD. AIM: To evaluate, through bibliometric and visual analysis, the current status of related research, related research frontiers, and the developmental trends in the field of diet and NAFLD. METHODS: We retrieved publications about diet and NAFLD published between 1987 and 2022 from Scopus. Next, we used VOSviewer 1.6.20 to perform bibliometric analysis and visualization. RESULTS: We found a total of 1905 studies, including 1637 (85.93%) original articles and 195 (10.24%) reviews, focused on the examination of NAFLD and its correlation with diet that were published between 1987 and 2022. Among the remaining five types of documents, 38 were letters, notes, editorials, meeting minutes, or brief surveys, representing 1.99% of the total documents. The countries with the most publications on this topic were China (n = 539; 28.29%), followed by the United States (n = 379; 19.90%), Japan (n = 133; 6.98%), and South Korea (n = 127; 6.6%). According to the citation analysis, the retrieved papers were cited an average of 32.3 times and had an h-index of 106, with 61014 total citations. The two main clusters on the map included those related to: (1) Inflammation and oxidative stress; and (2) Dietary interventions for NAFLD. CONCLUSION: This was the first study to use data taken from Scopus to visualize network mapping in a novel bibliometric analysis of studies focused on diet and NAFLD. After 2017, the two domains that received the most attention were "dietary interventions for NAFL"' and "'inflammation and oxidative stress implicated in NAFLD and its correlation with diet." We believe that this study provides important information for academics, dietitians, and doctors, and that additional research on dietary interventions and NAFLD is warranted.

Trends and Characteristics of Brown Rice Consumption among Adults in Japan: An Analysis of the National Health and Nutrition Surveys, 2012-2019.

Brown rice is a familiar whole grain in Japan. We examined national trends in brown rice consumption among Japanese adults aged ≥20 years old, using individual-level data from the National Health and Nutrition Surveys conducted between 2012 and 2019. We employed multivariable logistic regression to identify factors associated with brown rice consumption. The 95th percentile of daily brown rice intake remained at 0.0 g throughout the study period. The percentage of brown rice consumers increased from 1.8% (95% confidence interval: 1.6-2.1) in 2012 to 2.6% (95% confidence interval: 2.0-3.4) in 2019. Compared with individuals who consumed only white rice, brown rice consumers had significantly higher mean intake levels of macronutrients, legumes, vegetables, fruits, and nuts. Brown rice consumption was positively associated with certain sociodemographic characteristics (being female, older age, residing in a major city, living without very young children, and having higher education levels) and health behaviors (lower body mass index, engaging in regular exercise, and being a former or never smoker). Despite its potential nutritional benefits in balanced diets, only a small fraction of adults in Japan consume brown rice, indicating a need for further promotion, particularly among individuals with characteristics associated with brown rice consumption.

Temporal trend of food consumption markers, breakfast consumption and association with overweight/obesity in schoolchildren aged 7 to 10 years between 2007 and 2019.

Obesity has a multifactorial origin. Among the behavioural risk factors, excessive consumption of unhealthy foods, skipping breakfast and reduced physical activity stand out. The main objective of this article was to identify trends in dietary habits and their association with overweight/obesity over a 12-year period in schoolchildren aged 7 to 10 years in Florianópolis, southern Brazil. A cross-sectional panel analysis study, using anthropometric, sociodemographic, physical activity and food consumption data of schoolchildren aged 7 to 10 years, collected in three waves of the Study of Prevalence of Obesity in Children and Adolescents (EPOCA), carried out during the years 2007, 2012/2013 and 2018/2019, was performed. To analyse the trend in dietary variables over the years, the 95% CIs were compared with the non-overlap of intervals indicating statistical significance. Multiple logistic regression analysis was performed to test the association of weight status with dietary markers. The prevalence of overweight/obesity was 34.4%, 37.2% and 34.2% in 2007, 2012/2013 and 2018/2019, respectively, and there were no statistically significant differences among waves. There was a progressive and significant reduction in the consumption of soft drinks and sweets and in eating breakfast by schoolchildren, from 2007 to 2019. Breakfast consumption was inversely associated with the chance of overweight/obesity (OR 0.74, 95% CI 0.59-0.93), and female students were less likely to have overweight/obesity when compared to boys (OR 0.70, 95% CI 0.61-0.81). The reduction in the consumption of soft drinks and sweets over the years might be caused by efforts in public policies that intended to reduce the consumption of unhealthy foods among schoolchildren. The progressive and significant reduction in having breakfast should be better elucidated in future studies, to minimise the potential impact of this practice on schoolchildren's bodyweight.

Temporal trends of food consumption patterns in Tuvalu under the context of climate change: COMmunity-based Behavior and Attitude survey in Tuvalu (COMBAT) since 2020.

AIM: The aim of this study was to analyze temporal trends of food consumption patterns, attitudes, and health-related knowledge in Tuvalu, a small Pacific Island country facing the triple threat of obesity, climate change, and food insecurity. METHODS: Two waves of the COMmunity-based Behavior and Attitude (COMBAT) survey were conducted in 2020 and 2022. Descriptive characteristics of changes in obesity proportion, food intake, and sociodemographic factors were assessed. Additionally, this study also integrates individual climate data utilizing satellite-based prediction models, and estimates historical temperature, precipitation, and sea level trends among all islands in Tuvalu. RESULTS: The study revealed a high obesity proportion among adults (69.5% in 2020, 73.2% in 2022) and an increase in the percentage of adolescents with a high waist circumference. Variations in food intake were also observed between the two waves of the survey. CONCLUSIONS: The data collected in the COMBAT study provides valuable insights for future epidemiological research to elucidate the associations and causal relationships between climate change, food security, and non-communicable diseases in Tuvalu.

Dietary trends and obesity in Saudi Arabia.

Introduction: Dietary habits in Saudi Arabia have been shifting toward the Western diet, which is high in fat, salt, and sugar, leading to a high obesity rate. Different dietary strategies such as the Ketogenic Diet (KD), Intermittent Fasting (IF), Gluten Free Diet (GFD), and Calorie Restriction Diet (CRD) have shown an influential role in weight loss. This study aimed to compare trending diets and correlate different types of diet with obesity and lifestyle among adults in Saudi Arabia. Methods: A cross-sectional study was performed on Saudis and non-Saudis over 18 years old. We used convenience sampling, an online questionnaire distributed via social media channels, including WhatsApp, LinkedIn, and Twitter. SPSS 28 software was applied for data analysis. The chi-square test was used to determine associations between different variables. Statistical significance was considered at a value of p less than 0.05. Results: Most participants were females residing in the Eastern and Central regions of Saudi Arabia. Although most do not follow any dietary plan, they exhibited acceptable exercise and lifestyle. The minority of the study population followed different types of diet plans, such as KD, IF, and GFD. The purpose of most of the participants who have used these strategies was for weight loss but failed to sustain the dietary plan for more than 1 month. Conclusion: Obesity remains a challenging issue in Saudi Arabia. Adherence to dietary regimes could help in controlling obesity. Increasing the awareness of the benefits of each dietary plan for health, choosing the appropriate one, and sustaining a balanced nutrition pattern.

Framing the Latin American nutrition transition in a historical perspective, 1850 to the present / A constituição da transição nutricional latino-americana em uma perspectiva histórica, 1850 até o presente

Abstract This paper argues that many of the foundations and trends that led to the rise in obesity and other diet-related health problems in Latin America began to develop in the late nineteenth century. The tendency towards presentism in the nutrition transition literature provides a much abbreviated and limited history of changes in diet and weight. Whereas medical and nutrition researchers have tended to emphasize the recent onset of the crisis, a historical perspective suggests that increasingly global food sourcing prompted changes in foodways and a gradual "fattening" of Latin America. This paper also provides a methodological and historiographic exploration of how to historicize the nutrition transition, drawing on a diverse array of sources from pre-1980 to the present.

Resumo Este trabalho argumenta que fundamentos e tendências que levaram ao aumento da obesidade e de outros problemas de saúde relacionados à alimentação na América Latina começaram a surgir no final do século XIX. A propensão ao presentismo na literatura sobre transição nutricional produz uma história abreviada e limitada das mudanças em alimentação e peso. Embora pesquisadores médicos e nutricionistas enfatizem a recente instalação da crise, uma perspectiva histórica sugere que fontes alimentares crescentemente globalizadas resultaram em mudanças na alimentação e em gradual "aumento de gordura" na população latino-americana. O artigo propõe ainda a exploração metodológica e historiográfica de como historicizar a transição nutricional recorrendo a fontes pré-1980 até o momento.

Anthropometric and dietary assessment of patients with glycogenosis type i / Avaliação antropométrica e dietética de pacientes com glicogenose tipo i

ABSTRACT Objective: To perform anthropometric and dietary evaluation of patients with glycogenosis type Ia and Ib. Methods: This cross-sectional study is composed of a sample of 11 patients with glycogenosis divided into two subgroups according to the classification of glycogenosis (type Ia=5 and type Ib=6), aged between 4 and 20 years. The analyzed anthropometric variables were weight, height, body mass index, and measures of lean and fat body mass, which were compared with reference values. For dietary assessment, a food frequency questionnaire was used to calculate energy and macronutrients intake as well as the amount of raw cornstarch consumed. Mann-Whitney U test and Fisher's exact test were performed, considering a significance level of 5%. Results: Patients ingested raw cornstarch in the amount of 0.49 to 1.34 g/kg/dose at a frequency of six times a day, which is lower than recommended (1.75-2.50 g/kg/dose, four times a day). The amount of energy intake was, on average, 50% higher than energy requirements; however, carbohydrate intake was below the adequacy percentage in 5/11 patients. Short stature was found in 4/10 patients; obesity, in 3/11; and muscle mass deficit, in 7/11. There were no statistical differences between the subgroups. Conclusions: In patients with glycogenosis type I, there was deficit in growth and muscle mass, but no differences were found between the subgroups (Ia and Ib). Although the diet did not exceed the adequacy of carbohydrates, about 1/3 of the patients presented obesity, probably due to higher energy intake.

RESUMO Objetivo: Realizar avaliação antropométrica e dietética de pacientes com glicogenose tipos Ia e Ib. Métodos: Estudo transversal composto de uma amostra de 11 pacientes com glicogenose divididos em dois subgrupos de acordo com a classificação da glicogenose (tipo Ia=5; tipo Ib=6), com idades entre 4 e 20 anos. As variáveis antropométricas analisadas foram peso, estatura, índice de massa corporal e medidas de massa magra e gorda, que foram comparadas com valores de referência. Para avaliação dietética, foi utilizado um questionário de frequência alimentar para cálculo de ingestão de energia e macronutrientes, além da quantidade de amido cru ingerida. Realizaram-se testes U de Mann-Whitney e exato de Fisher, com nível de significância de 5%. Resultados: Os pacientes ingeriram amido cru na quantidade de 0,49 a 1,34 g/kg/dose na frequência de seis vezes ao dia, inferior à dosagem preconizada (1,75-2,50 g/kg/dose quatro vezes ao dia). A quantidade de energia consumida foi, em média, 50% a mais que as necessidades, contudo o consumo de carboidratos foi abaixo da porcentagem de adequação em 5/11 pacientes. Baixa estatura ocorreu em 4/10 pacientes, obesidade em 3/11 e déficit de massa muscular em 7/11. Não houve diferença estatística entre os subgrupos. Conclusões: Em pacientes com glicogenose tipo I, houve déficit de crescimento e de massa muscular, mas não diferença significante entre os subgrupos (Ia e Ib). Embora a dieta não tenha ultrapassado a adequação de carboidratos, 1/3 dos pacientes apresentou obesidade, provavelmente pela maior ingestão de energia.

Tendência de padrões alimentares entre adultos das capitais brasileiras / Trend in dietary patterns among adults from Brazilian state capitals

RESUMO: Objetivo: Descrever e analisar a tendência dos padrões alimentares praticados pela população adulta de 18 a 44 anos das capitais brasileiras entre os anos de 2007 e 2012. Métodos: Padrões alimentares foram identificados com análise de componentes principais (ACP). Na análise, foram retidos os componentes com autovalores > 1,0 e foram destacadas cargas fatoriais (CF) superiores a -0,2-. Após a identificação de quatro padrões foram gerados escores padronizados com média zero para cada. As médias foram apresentadas para cada padrão segundo sexo, faixa etária, escolaridade e ano de monitoramento. A variação temporal da média dos escores dos padrões foi estimada por regressão linear. Resultados: Foram identificados quatro padrões alimentares na população: prudente, transição, ocidental e tradicional. Houve tendência de aumento das médias de escore dos padrões: prudente, ocidental e tradicional, e redução da média de escore do padrão transição. Maior aderência ao padrão prudente entre indivíduos mais escolarizados. Maior aderência aos padrões ocidental e tradicional entre indivíduos menos escolarizados. Conclusão: Políticas públicas direcionadas aos indivíduos menos escolarizados e homens são necessárias por causa da maior adesão aos padrões alimentares não saudáveis.

ABSTRACT: Objective: To describe and analyze the trend in dietary patterns followed by the adult population aged 18 to 44 years living in Brazilian state capitals between 2007 and 2012. Methods: We identified dietary patterns using the principal component analysis (PCA). The analysis retained components with eigenvalues >1.0 and highlighted factor loadings (FLs) >-0.2-. After the identification of four patterns, they received standardized scores with zero mean. The mean scores were presented for each pattern according to gender, age group, schooling, and year of data collection. We estimated the temporal variation of the mean scores of the patterns by linear regression. Results: We identified four dietary patterns in the population: prudent, transition, western, and traditional. We found an increasing trend in the mean score of the patterns: prudent, western, and traditional and a reduced mean score in the transition pattern. Individuals with better education showed greater adherence to the prudent pattern. Less-educated individuals presented higher adherence to the western and traditional patterns. Conclusion: Public policies targeting the population with lower schooling and men are necessary due to their greater adherence to unhealthy dietary patterns.

Dietary changes in the NutriNet Brasil cohort during the covid-19 pandemic / Mudanças alimentares na coorte NutriNet Brasil durante a pandemia de covid-19

ABSTRACT OBJECTIVE To describe the dietary characteristics of participants in the NutriNet Brasil cohort immediately before and during the covid-19 pandemic. METHODS Our data stem from an adult cohort created to prospectively investigate the relationship between diet and morbidity and mortality from chronic non-communicable diseases in Brazil. For this study, we selected the first participants (n = 10,116) who answered twice to a simplified questionnaire on their diet the day before, the first time when entering the study, between January 26 and February 15, 2020, and the second between May 10 and 19, 2020. The questionnaire inquiries about the consumption of healthy (vegetables, fruits and legumes) and unhealthy (ultra-processed foods) eating markers. Comparisons of indicators based on the consumption of these markers before and during the pandemic are presented for the study population and according to gender, age group, macro-region of residence and schooling. Chi-square tests and t-tests were used to compare proportions and means, respectively, adopting p < 0.05 to identify significant differences. RESULTS For all participants, we found a modest but statistically significant increase in the consumption of healthy eating markers and stability in the consumption of unhealthy food markers. This favorable pattern of dietary changes during the pandemic occurred in most sociodemographic strata. We observed a less favorable changing pattern, with a tendency to increasing consumption of healthy and unhealthy food markers, in the Northeast and North macro-regions and among people with less schooling, suggesting social inequalities in the response to the pandemic. CONCLUSIONS If confirmed, the trend of increased consumption of ultra-processed foods in underdeveloped regions and by people with less schooling is concerning, as eating these foods increases the risk of obesity, hypertension and diabetes, whose presence increases the severity and lethality of covid-19.

RESUMO OBJETIVO Descrever características da alimentação dos participantes da coorte NutriNet Brasil imediatamente antes e na vigência da pandemia de covid-19. MÉTODOS Os dados deste estudo provêm de coorte de adultos criada para investigar prospectivamente a relação entre alimentação e morbimortalidade por doenças crônicas não transmissíveis no Brasil. Para este estudo, foram selecionados os primeiros participantes (n = 10.116) que responderam por duas vezes a questionário simplificado sobre sua alimentação no dia anterior, a primeira vez ao ingressar no estudo, entre 26 de janeiro e 15 de fevereiro de 2020, e a segunda entre 10 e 19 de maio de 2020. O questionário indaga sobre o consumo de marcadores de alimentação saudável (hortaliças, frutas e leguminosas) e não saudável (alimentos ultraprocessados). Comparações de indicadores baseados no consumo desses marcadores antes e na vigência da pandemia são apresentadas para o conjunto da população estudada e segundo sexo, faixa etária, macrorregião de residência e escolaridade. Testes qui-quadrado e testes t foram utilizados para comparar proporções e médias, respectivamente, adotando-se p < 0,05 para identificar diferenças significantes. RESULTADOS Para o conjunto dos participantes, identificou-se aumento modesto, porém estatisticamente significante, no consumo de marcadores de alimentação saudável e estabilidade no consumo de marcadores de alimentação não saudável. Esse padrão favorável de mudanças na alimentação com a pandemia se repetiu na maior parte dos estratos sociodemográficos. Padrão menos favorável de mudanças, com tendência de aumento no consumo de marcadores de alimentação saudável e não saudável, foi observado nas macrorregiões Nordeste e Norte e entre pessoas com menor escolaridade, sugerindo desigualdades sociais na resposta à pandemia. CONCLUSÕES Caso confirmada, a tendência de aumento no consumo de alimentos ultraprocessados nas regiões economicamente menos desenvolvidas e por pessoas com menor escolaridade preocupa, pois a ingestão desses alimentos eleva o risco de obesidade, hipertensão e diabetes, cuja presença aumenta a gravidade e a letalidade da covid-19.

Association between body weight perception and quality of diet in brazilian adolescents / Associação da percepção do peso corporal com a qualidade da dieta de adolescentes brasileiros

ABSTRACT Objective: To evaluate the association between body weight perception and quality of diet among Brazilian adolescents. Methods: The sample was composed of 71,740 adolescents aged from 12 to 17 years-old enrolled in the Study of Cardiovascular Risks in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes - ERICA), carried out during 2013-2014. Body weight perception was self-reported. Food consumption was assessed by food record and quality of diet index for Brazilian adolescents (DQIA-BR) was calculated, considering the balance, diversity, and diet composition. The quality of diet was compared according to weight perception for the entire sample and after stratification by nutritional status. Linear regression models were used to assess the association between body weight perception and quality of diet. Results: Among the studied adolescents, 14.7 and 30.3% reported to be underweight or overweight in relation to their desired weight, respectively. Those who perceived themselves as overweight had lower quality of diet (DQIA-BR=16.0 vs. 17.4 points; p<0.001). After stratification by BMI, adolescents with normal weight (DQIA-BR=15.3 points) or overweight (DQIA-BR=16.1 points), but who perceived themselves as overweight showed lower quality of diet when compared to their peers. In adjusted analysis, overweight perception (β= -0.51; 95%CI -0.77; -0.24) was associated to lower quality of diet. However, this association was no longer significant after stratification by BMI status. Conclusions: Body weight perception can influence the consumption of healthy foods and the quality of diet, especially for those who consider themselves overweight. However, this association is influenced by nutritional status.

RESUMO Objetivo: Avaliar a associação entre percepção de peso corporal e qualidade da dieta de adolescentes brasileiros. Métodos: A amostra estudada foi composta de 71.740 adolescentes de 12-17 anos participantes do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA) realizado entre 2013 e 2014. A percepção do peso corporal foi avaliada por questionário autoaplicável; o consumo alimentar, por recordatório alimentar; e a qualidade da dieta pelo índice de qualidade da dieta de adolescentes brasileiros (IQDA-BR), considerando o equilíbrio, a diversidade e a composição da dieta. A qualidade da dieta foi comparada de acordo com a percepção do peso para toda a amostra e após estratificação por índice de massa corpórea (IMC). Modelos de regressão linear foram utilizados para avaliar a associação entre distúrbios na percepção do peso e qualidade da dieta. Resultados: Entre os adolescentes, 14,7 e 30,3% percebiam-se abaixo ou acima do peso, respectivamente. Aqueles que se percebiam acima do peso apresentaram menor qualidade da dieta (IQDA-BR=16,0 vs. 17,4 pontos; p<0,001). Após estratificação por IMC, adolescentes com peso normal (IQDA-BR=15,3 pontos) ou excesso de peso (IQDA-BR=16,1 pontos), mas que se percebiam como acima do peso, apresentaram pior qualidade da dieta se comparados ao demais. Em análise ajustada, perceber-se acima do peso (β= -0,51; intervalo de confiança de 95% - IC95% -0,77; -0,24) foi associado a pior qualidade da dieta, porém essa associação perdeu significância após a estratificação por IMC. Conclusões: A percepção do peso corporal parece influenciar o consumo de alimentos saudáveis e a qualidade da dieta principalmente daqueles que se consideram acima do peso, contudo essa associação é influenciada pelo estado nutricional.

Resumen Objetivo: determinar la asociación entre el apego a la dieta y la educación nutricional en los pacientes con tratamiento de diálisis. Material y métodos: estudio transversal en pacientes con enfermedad renal crónica (ERC) en tratamiento de diálisis ≥6 meses, que han recibido educación nutricional previamente. Se evaluó el estado de nutrición mediante la Valoración Global Subjetiva (VGS), toma de pliegues cutáneos (tricipital y subescapular), peso seco y estatura (de acuerdo con los parámetros establecidos por la International Society for Advances of Kinanthropometry); los conocimientos nutricionales y su adherencia mediante la Encuesta de Conocimientos y Adherencia al Régimen Terapéutico, y la calidad de vida mediante el instrumento KDQOL-SF™. Resultados: se incluyeron 85 pacientes, 46 (54%) hombres y 39 (46%) mujeres con una edad media de 42 ±17 años y un tiempo medio en diálisis de 3 ± 1.96 años. El 58% de los pacientes no presentó apego al régimen dietético. Sin embargo, el 89% de los pacientes se apegaron a la recomendación de la restricción de sodio, mientras que el 59% se adhirió al consumo de líquidos. De acuerdo con la VGS, el 58% de los pacientes presentaron desnutrición leve/moderada; no obstante, el 71% tuvieron grasa promedio según la sumatoria de pliegues y el 67% presentó un estado de nutrición normal determinado por el de Índice de Masa Corporal (IMC). Conclusiones: no se observó diferencia significativa en la adherencia al tratamiento dietético en aquellos pacientes que tienen conocimientos nutricionales respecto a los que no los tienen.

Abstract Objetive: to determine the association between adherence to the diet and nutritional education in patients with dialysis treatment. Material and Methods: Cross-sectional descriptive study in patients with Chronic Kidney Disease on dialysis treatment ≥6 months, who have previously received nutritional education. The State of Nutrition was evaluated by means of the Subjective Global Assessment (SGA), skinfolds (tricipital and subescapular), dry weight and height (according to the parameters established by the International Society for Advances of Kinanthropometry); nutritional knowledge and adherence through the Knowledge and Adherence to The Therapeutic Regimen Survey; quality of life through the KDQOL-SF ™ instrument. Results: 85 patients were included, 46 (54%) men and 39 (46%) women with an average age of 42 ± 17 years and a mean time with dialysis treatment 3 ± 1.96 years. 58% of the patients did not have adherence to the diet. However, 89% of patients adhered to the sodium restriction recommendation, while 59% adhered to fluid intake. According to the VGS, 58% of the patients presented mild/moderate malnutrition, however, 71% had average fat according to the sum of the skinfolds and 67% presented a normal nutritional status determined by Body Mass Index (BMI). Conclusions: no significant difference in adherence to dietary treatment was observed in those patients who have nutritional knowledge compared to those who do not.

Tendências temporais do consumo de frutas e hortaliças entre adultos nas capitais brasileiras e Distrito Federal, 2008-2016 / Time trends in the consumption of fruits and vegetables among adults in Brazilian state capitals and the Federal District, 2008-2016 / Tendencias temporales del consumo de frutas y hortalizas entre adultos en capitales brasileñas y Distrito Federal, 2008-2016

Resumo: Analisar a tendência temporal do consumo de frutas e hortaliças entre adultos nas capitais brasileiras e no Distrito Federal no período entre 2008 e 2016. Trata-se de um estudo de série temporal, com dados do VIGITEL de 2008 a 2016 (n = 463.817). Analisou-se o percentual de consumo regular (≥ 5 dias/semana) e recomendado (≥ 5x/dia) de frutas e hortaliças, para cada um dos anos, para o conjunto completo da população e segundo sexo, faixa de idade, nível de escolaridade e localidade. A presença de tendência linear (de aumento ou diminuição) na variação dos indicadores foi analisada por meio da regressão Prais-Winsten. Verificou-se aumento significativo (p < 0,05) na prevalência de consumo regular (de 33 a 35,2%, aumento de 1,86%/ano) e de consumo recomendado de frutas e hortaliças (de 20 a 24,4%, aumento de 3,32%/ano). Tendência semelhante foi identificada para o percentual da população atendendo a recomendação de consumo na maior parte dos estratos populacionais, com maior magnitude de aumento entre: homens (4%/ano vs. 3,05%/ano para as mulheres), adultos jovens (3,97%/ano para aqueles com idades entre 18 e 24 anos vs. 2,3%/ano para os que têm de 55-64 anos), aqueles com menor escolaridade (2,97%/ano para aqueles com 0-8 anos de estudos vs. 2,76%/ano para os com 12 anos ou mais) e residentes em regiões menos desenvolvidas (5,02%/ano na Região Norte vs. 2,6%/ano na Região Sudeste). Observou-se aumento do consumo de frutas e hortaliças especialmente entre os grupos com menor nível de consumo no início do período estudado. No entanto, 3 a cada 4 indivíduos permanecem consumindo menos frutas e hortaliças do que o recomendado.

Abstract: The study aimed to analyze the time trend in the consumption of fruits and vegetables among adults in Brazilian state capitals and the Federal District from 2008 to 2016. This was a time series study with data from the VIGITEL survey from 2008 to 2016 (n = 463,817). The study analyzed the prevalence of regular consumption (≥ 5 days/week) and recommended consumption (≥ 5 times/day) of fruits and vegetables, for each of the years, for the complete set of the evaluated population and according to sex, age group, schooling, and location. Presence of linear trend (increase or decrease) in the indicators' variation was analyzed by Prais-Winsten regression. There was a significant increase (p < 0.05) in prevalence of regular consumption (from 33 to 35.2%, an increase of 1.86%/year) and recommended consumption of fruits and vegetables (from 20 to 24.4%, an increase of 3.32%/year). A similar trend was identified in the percentage of the population meeting the recommended consumption in most of the population strata, with the highest increase in men (4%/year vs. 3.05%/year for women), young adults (3.97%/year in the 18-24-year group vs. 2.30%/year in the 55-64-year group), those with low schooling (2.97%/year for 0 to 8 years of schooling vs. 2.76%/year for 12 years or more), and less developed regions of Brazil (5.02%/year in the North vs. 2.6%/year in the Southeast). There was an increase in the consumption of fruits and vegetables, especially among groups with lower levels of consumption at the start of the study period. However, three out of four individuals still consumed fewer fruits and vegetables than recommended.

Resumen: El objetivo de este estudio fue analizar la tendencia temporal del consumo de frutas y hortalizas entre adultos en las capitales brasileñas y Distrito Federal durante el período entre 2008 y 2016. Se trata de un estudio de serie temporal, con datos procedentes de VIGITEL entre 2008 y 2016 (n = 463.817). Se analizó el porcentaje de consumo regular (≥ 5 días/semana) y recomendado (≥ 5x/día) de frutas y hortalizas, en cada uno de los años, para el conjunto completo de la población y según sexo, franja de edad, nivel de escolaridad y lugar de residencia. La presencia de una tendencia lineal (de aumento o disminución) en la variación de los indicadores se analizó mediante la regresión Prais-Winsten. Se verificó un aumento significativo (p < 0,05) en la prevalencia del consumo regular (de 33 a 35,2%, un aumento de 1,86%/año) y del consumo recomendado de frutas y hortalizas (del 20 al 24,4%, un aumento de 3,32%/año). Una tendencia semejante se identificó respecto al porcentaje de la población que respondía a la recomendación de consumo en la mayor parte de los estratos poblacionales, con mayor magnitud de aumento entre: hombres (4%/año vs. 3,05%/año para las mujeres), adultos jóvenes (3,97%/año para aquellos con edad entre 18 y 24 años vs. 2,30%/año para aquellos con 55-64 años), aquellos con menor escolaridad (2,97%/año para aquellos de 0 a 8 años de estudios vs. 2,76%/año para aquellos con 12 años o más) y residentes en regiones menos desarrolladas (5,02%/año en la región norte vs. 2,6%/año en la región sudeste). Se observó un aumento del consumo de frutas y hortalizas, especialmente, entre los grupos con menor nivel de consumo durante el inicio del período estudiado. No obstante, 3 de cada 4 individuos siguen consumiendo menos frutas y hortalizas de lo recomendado.

Evolução da ingestão de energia e nutrientes de adolescentes de escolas públicas de Niterói, Rio de Janeiro, Brasil, 2003-2008 / Trends in energy and nutrient intake by adolescents in public schools in Niterói, Rio de Janeiro State, Brazil, 2003-2008 / Evolución de la ingestión de energía y nutrientes en adolescentes de escuelas públicas de Niteroi, Río de Janeiro, Brasil, 2003-2008

Resumo: Analisaram-se as variações na ingestão de energia e nutrientes de adolescentes, estudantes de escolas públicas, examinados em dois estudos de base escolar, com desenho seccional, realizados em 2003 e 2008. O consumo alimentar foi avaliado com a aplicação de três registros alimentares. A condição de peso foi classificada segundo os critérios da Organização Mundial da Saúde. Em 2003, foram investigados 433 adolescentes, e, em 2008, 510 adolescentes. A prevalência de excesso de peso foi de 17%, em 2003, e de 22%, em 2008 (p > 0,05). Observou-se redução na ingestão de gorduras saturadas e de vitamina A entre os meninos. Entre as meninas, houve incremento na ingestão de energia, carboidratos e cálcio e redução para proteína e ferro. Ambos os grupos reduziram a ingestão de vitamina E e de lipídios e aumentaram a de sódio. Entre os adolescentes sem excesso de peso, observou-se incremento da ingestão de cálcio, e, para aqueles com peso excessivo, houve redução de gordura saturada e de vitamina A. No decorrer de cinco anos, a dieta dos adolescentes sofreu prejuízo da qualidade nutricional.

Abstract: The study analyzed variations in energy and nutrient intake by adolescents enrolled in public schools, examined in two school-based cross-sectional surveys, in 2003 and 2008. Food consumption was assessed with three food records. Weight was classified according to World Health Organization criteria. A total of 433 adolescents were studied in 2003 and 510 in 2008. Prevalence of excess weight was 17% in 2003 and 22% in 2008 (p > 0.05). There was a reduction in the intake of saturated fats and vitamin A in boys. Girls showed an increase in the intake of energy, carbohydrates, and calcium and a reduction in protein and iron. Both boys and girls reduced their intake of vitamin E and lipids and increased their sodium. Adolescents with excess weight showed an increase in calcium intake and a decrease in saturated fat and vitamin A. The nutritional quality of the adolescents' diet declined over the course of the five years.

El consumo alimenticio fue evaluado con la aplicación de tres registros alimentarios. La condición de peso fue clasificada según los criterios de la Organización Mundial de la Salud. En 2003, se investigaron a 433 adolescentes y en 2008, a 510 adolescentes. La prevalencia de exceso de peso fue de un 17% en 2003 y de un 22% en 2008 (p > 0,05). Se observó una reducción en la ingestión de grasas saturadas y vitamina A entre los niños. Entre las niñas, hubo un incremento en la ingestión de energía, carbohidratos y calcio y reducción para proteína e hierro. Ambos grupos redujeron la ingestión de vitamina E y lípidos y aumentaron la de sodio. Entre los adolescentes sin exceso de peso se observó un incremento de la ingestión de calcio, y para aquellos con peso excesivo hubo reducción de grasa saturada y vitamina A. En el transcurso de cinco años la dieta de los adolescentes sufrió un perjuicio de su calidad nutricional.

Diet quality among adolescents has deteriorated: a panel study in Niterói, Rio de Janeiro State, Brazil, 2003-2008 / A queda na qualidade da alimentação dos adolescentes brasileiros: um estudo de painel em Niterói, Estado do Rio de Janeiro, Brasil, 2003-2008 / La caída en la calidad de la alimentación de los adolescentes brasileños: un estudio de panel en Niterói, Estado de Río de Janeiro, Brasil, 2003-2008

This study aimed to analyze changes in the diet quality of adolescents from public schools in Niterói, Rio de Janeiro State, Brazil, over a five-year period. Data on the food consumption of adolescents (12-19 years) were obtained by means of two sets of 3-day food records in two school-based, cross-sectional studies conducted in 2003 and 2008. The Brazilian Revised Healthy Eating Index (BHEI-R) was used to estimate dietary quality. From 2003 to 2008 there was an overall decrease in the scores attributed to "total vegetables", "dark green and orange vegetables", and "meat, eggs, and legumes", but there was an increase in the score for "milk and dairy" (4.0 vs. 5.2; p < 0.01). Among female adolescents, the BHEI-R decreased (64.1 vs. 62.4; p = 0.04), as did the scores attributed to "total vegetables", "dark green and orange vegetables", "meat, eggs, and legumes", and "solid fat, alcohol, and added sugar". In contrast, among males, only the "whole grains" score decreased (0.2 vs. 0.1; p = 0.04). From 2003 to 2008, the diet quality of female public school students declined in Niterói.

O estudo teve como objetivo analisar as mudanças na qualidade da dieta de adolescentes matriculados em escolas públicas em Niterói, Estado do Rio de Janeiro, Brasil, ao longo de cinco anos. Os dados sobre consumo alimentar dos adolescentes (12-19 anos de idade) foram obtidos através de dois conjuntos de registros alimentares de três dias em dois estudos transversais de base escolar, em 2003 e 2008. O Índice Brasileiro de Alimentação Saudável (IAS-R) versão revisada, foi utilizado para estimar a qualidade da dieta. Entre 2003 e 2008, houve uma queda geral na pontuação atribuída a "total de verduras e hortaliças", "verduras e hortaliças de cor laranja" e "carne, ovos e legumes", mas houve um aumento no consumo de "leite e laticínios" (4,0 vs. 5,2; p < 0,01). Entre adolescentes femininas, houve uma queda do IAS-R (64,1 vs. 62,4; p = 0,04), assim como, do consumo de "total de verduras e hortaliças", "verduras e hortaliças de cor laranja", "carne, ovos e legumes" e "gordura sólida, álcool e açúcar". Por outro lado, entre adolescentes masculinos, houve uma queda apenas no consumo de "cereais integrais" (0,2 vs. 0,1; p = 0,04). Entre 2003 e 2008, a qualidade da dieta de adolescentes femininas deteriorou em Niterói.

El estudio tuvo como objetivo analizar los cambios en la calidad de la dieta de adolescentes matriculados en escuelas públicas en Niterói, Estado de Río de Janeiro, Brasil, a lo largo de cinco años. Los datos sobre consumo alimentario de los adolescentes (12-19 años de edad) fueron obtenidos a través de dos conjuntos de registros alimentarios de tres días, en dos estudios transversales de base escolar, en 2003 y 2008. El Índice Brasileño de Alimentación Saludable (IAS-R), versión revisada, se utilizó para estimar la calidad de la dieta. Entre 2003 y 2008, hubo una caída general en la puntuación atribuida al "total de verduras y hortalizas", "verduras y hortalizas de color naranja" y "carne, huevos y legumbres", pero hubo un aumento en el consumo de "leche y lácteos" (4,0 vs. 5,2; p < 0,01). Entre adolescentes femeninas hubo una caída del IAS-R (64,1 vs. 62,4; p = 0,04), así como, del consumo de "total de verduras y hortalizas", "verduras y hortalizas de color naranja", "carne, huevos y legumbres" y "grasa sólida, alcohol y azúcar". Por otro lado, entre adolescentes masculinos, hubo una caída sólo en el consumo de "cereales integrales" (0,2 vs. 0,1; p = 0,04). Entre 2003 y 2008, la calidad de la dieta de adolescentes femeninas se deterioró en Niterói.
