Introducción. La acelerada transición nutricional en Latinoamérica ha modificado los patrones alimentarios, favoreciendo dietas con mayor participación de productos industrializados y alto aporte de nutrientes relacionados con enfermedades crónicas como grasas (saturadas, trans), sodio, azúcar libre y densidad de energía. Objetivo. Describir los momentos alimentarios de consumo de productos comestibles ultraprocesados (PCUP) durante el día en Antioquia, Colombia. Materiales y métodos. Estudio descriptivo transversal, usando datos de consumo de alimentos del Perfil Alimentario y Nutricional de Antioquia 2019 y del Perfil de Seguridad Alimentaria y Nutricional de Medellín 2015, en población general, muestra de 13494 individuos. Los alimentos se clasificaron según NOVA y se agruparon en subcategorías. Se calculó la media de energía consumida y su desviación estándar (confianza del 95%) para las categorías NOVA y subcategorías, además su distribución en los momentos alimentarios. Resultados. Para la población de Medellín (capital de Antioquia), en promedio el 54,7% de la energía venia de alimentos no procesados, 17,3% de ingredientes culinarios, y 20,4% de PCUP. En la población de Antioquia, 56,0% de la energía se obtuvo de alimentos no procesados, 18,8% de ingredientes culinarios y 17,0% de PCUP. En los momentos alimentarios principales (desayuno, almuerzo y cena) los alimentos no procesados tienen mayor aporte energético. Mientras que los momentos alimentarios con mayor porcentaje de energía proveniente de PCUP fueron la media mañana, el algo y la merienda. Conclusiones. Para los antioqueños el mayor riesgo de consumo de PCUP relacionados con la obesidad y las enfermedades crónicas se presenta entremedio de las comidas principales(AU)

Introduction. The accelerated nutritional transition in Latin America has modified dietary patterns, favoring diets with a greater participation of industrialized products and a high contribution of nutrients related to chronic diseases such as fats (saturated, trans), sodium, free sugar, and energy density. Objective. To describe the dietary moments of consumption of ultra-processed foods (UPF) during the day in Antioquia, Colombia. Materials and methods. Cross-sectional descriptive study using food consumption data from the Food and Nutrition Profile of Antioquia 2019 and the Food and Nutrition Security Profile of Medellín 2015, in general population, sample of 13,494 individuals. Foods were classified according to NOVA and grouped into subcategories. The mean energy consumed and its standard deviation (95% confidence), were calculated for the NOVA categories and subcategories, as well as its distribution at feeding times. Results. for the population of Medellín (capital of Antioquia), on average 54.7% of the energy came from unprocessed foods, 17.3% from culinary ingredients, and 20.4% from UPF. In the population of Antioquia, 56.0% of the energy was obtained from unprocessed foods, 18.8% from culinary ingredients, and 17.0% from UPF. At the main eating moments (breakfast, lunch, and dinner) unprocessed foods have a greater energy contribution. While the food moments with the highest percentage of energy coming from UPF were mid-morning snacks and snacks. Conclusions. For Antioqueños the greatest risk of consuming UPFs related to obesity and chronic diseases occurs between main meals(AU)

Ingesta de alimentos ultraprocesados y circunferencia de cintura según área de residencia en adultos peruanos / Ultra-processed food consumption and waist circumference by residence setting in Peruvian adults

Introducción. La circunferencia de cintura (CC) es indicador de obesidad abdominal y riesgo cardiovascular en adultos. En Perú, la obesidad ha aumentado a diferente magnitud por área de residencia y poco se sabe de la influencia del consumo de alimentos ultraprocesados (AUP) sobre este fenómeno en población adulta. Objetivo. Evaluar la asociación entre ingesta de AUP y circunferencia de cintura en adultos peruanos por área de residencia. Materiales y métodos. Estudio transversal de datos secundarios de 745 adultos con información de ingesta dietaria (un recordatorio de 24 horas) de la Encuesta Nacional Vigilancia Alimentaria y Nutricional por Etapas de Vida 2017-2018. Los AUP fueron caracterizados según la clasificación NOVA. La ingesta AUP como el porcentaje relativo de la ingesta energética total (%), dividida en terciles. La CC medida como punto medio entre última costilla y cresta iliaca. Se usó regresión lineal múltiple ponderada y análisis estratificado según área de residencia. Resultados. La edad promedio fue 37,2 años. La ingesta de AUP promedio fue 14,7% (IC95%: 14,2 ­ 15,3). Comparado con adultos en el menor tercil de ingesta de AUP, aquellos en tercil medio tuvieron mayor CC ( 0,73; IC95%: 0,22 ­ 1,24; valor p= 0,007). Al estratificar por área de residencia, adultos rurales del tercil medio tuvieron mayor CC en comparación con primer tercil ( : 1,85; IC95%: 1,17 ­ 2,53, valor p < 0,001). Conclusiones. En adultos peruanos, la ingesta de AUP se asoció a CC en áreas rurales, aunque no de forma lineal. Más estudios son necesarios para entender la naturaleza de esta asociación(AU)

Introduction. Waist circumference (WC) is an abdominal obesity and cardiovascular risk indicator among adults. In Peru, obesity prevalence has been increasing unequally between residence areas, and the influence of ultra- processed food (UPF) consumption on WC in Peruvian adults remains unclear. Objective. Evaluate the association between UPF consumption and waist circumference by residence setting among Peruvian adults. Materials and methods. A cross-sectional secondary analysis of dietary intake data (single 24-hour recall) from 745 adults aged 18 and 59 years old from the "Vigilancia Alimentaria y Nutricional por Etapas de Vida 2017-2018" National Surveys was performed. The NOVA system was used to characterize the UPFs, and the exposure was the percentage of total energy consumed from UPF per day (%), in quantiles. WC (cm) was assessed at the middle point between the last rib and the iliac crest. Weighted linear regression analysis stratified by residence areas were conducted. Results. The mean age was 37.2 years. The mean percent of total energy consumed from UPF was 14.7% (95%CI: 14.2 ­ 15.3). Those in the middle tertile of UPF consumption, had higher WC ( 0.73; 95%CI: 0.22 ­ 1.24; p-value = 0.007) compared with those in the lower tertile. In the stratified analysis, those in the second tertile in rural areas have more WC compared with the first tertile ( 1.85; 95%CI: 1.17 ­ 2.53, p-value< 0.001). Conclusions. In rural areas, UPF consumption was associated with waist circumference, but it does not follow a linear association. Further studies are needed to understand the rationale behind these results(AU)

Nutritional status and temporal trend of coverage of Brazilian adolescents monitored in the Food and Nutritional Surveillance System, 2008 to 2019 / Estado nutricional e tendência temporal da cobertura de adolescentes brasileiros acompanhados no Sistema de Vigilância Alimentar e Nutricional, 2008 a 2019

Abstract Objectives: to analyze the nutritional status and temporal trend of the coverage of Brazilian adolescents monitored in the Food and Nutritional Surveillance System in the period 2008-2019. Methods: ecological study of temporal series with SISVAN data collected from 2008 to 2019 with 45,869.266 registration. Body mass index data were collected and the registration coverage of adolescents monitored by the system was calculated. The percentage of annual variation in coverage and nutritional status was estimated using Prais-Winsten regression, with a significance level of 5%. Results: an increase in the prevalence of obesity was observed between 2008 and 2019, during this period thinness remained stable in Brazil. National coverage evolved from 9.3% in 2008 to 19.6% in 2019, with an annual variation of 9% and a statistically significant increase trend. In Brazil, obesity in this age group increased between 2008 and 2019, with an annual variation of 8.7% (CI95% = 7.8-9.6). Conclusion: modifications were observed in nutritional status suggest the occurrence of nutritional transition in the adolescents' population. The percentage of coverage available in the system has growth potential, however, the current scenario impacts on a possible insufficient analysis to support the elaboration and reorientation of public policies.

Differences in food consumption of the Brazilian population by race/skin color in 2017-2018 / Diferenças no consumo alimentar da população brasileira por raça/cor da pele em 2017-2018

ABSTRACT OBJECTIVE To evaluate food consumption in Brazil by race/skin color of the population. METHODS Food consumption data from the Pesquisa de Orçamentos Familiares (POF - Household Budget Survey) 2017-2018 were analyzed. Food and culinary preparations were grouped into 31 items, composing three main groups, defined by industrial processing characteristics: 1 - in natura/minimally processed, 2 - processed, and 3 - ultra-processed. The percentage of calories from each group was estimated by categories of race/skin color - White, Black, Mixed-race, Indigenous, and Yellow- using crude and adjusted linear regression for gender, age, schooling, income, macro-region, and area. RESULTS In the crude analyses, the consumption of in natura/minimally processed foods was lower for Yellow [66.0% (95% Confidence Interval 62.4-69.6)] and White [66.6% (95%CI 66.1-67.1)] groups than for Blacks [69.8% (95%CI 68.9-70.8)] and Mixed-race people [70.2% (95%CI 69.7-70.7)]. Yellow individuals consumed fewer processed foods, with 9.2% of energy (95%CI 7.2-11.1) whereas the other groups consumed approximately 13%. Ultra-processed foods were less consumed by Blacks [16.6% (95%CI 15.6-17.6)] and Mixed-race [16.6% (95%CI 16.2-17.1)], with the highest consumption among White [20.1% (95%CI 19.6-20.6)] and Yellow [24.5% (95%CI 20.0-29.1)] groups. The adjustment of the models reduced the magnitude of the differences between the categories of race/skin color. The difference between Black and Mixed-race individuals from the White ones decreased from 3 percentage points (pp) to 1.2 pp in the consumption of in natura/minimally processed foods and the largest differences remained in the consumption of rice and beans, with a higher percentage in the diet of Black and Mixed-race people. The contribution of processed foods remained approximately 4 pp lower for Yellow individuals. The consumption of ultra-processed products decreased by approximately 2 pp for White and Yellow groups; on the other hand, it increased by 1 pp in the consumption of Black, Mixed-race, and Indigenous peoples. CONCLUSION Differences in food consumption according to race/skin color were found and are influenced by socioeconomic and demographic conditions.

RESUMO OBJETIVO Avaliar o consumo alimentar no Brasil por raça/cor da pele da população. MÉTODOS Foram analisados dados de consumo alimentar da Pesquisa de Orçamentos Familiares 2017-2018. Alimentos e preparações culinárias foram agrupados em 31 itens, compondo três grupos principais, definidos por características do processamento industrial: 1 - in natura/minimamente processados, 2 - processados e 3 - ultraprocessados. O percentual de calorias de cada grupo foi estimado por categorias de raça/cor da pele - branca, preta, parda, indígena e amarela -, utilizando-se regressão linear bruta e ajustada para sexo, idade, escolaridade, renda, macrorregião e área. RESULTADOS Nas análises brutas, o consumo de alimentos in natura/minimamente processados foi menor para amarelos [66,0% (Intervalo de Confiança 95% 62,4-69,6)] e brancos [66,6% (IC95% 66,1-67,1)] que para pretos [69,8% (IC95% 68,9-70,8)] e pardos [70,2% (IC95% 69,7-70,7)]. Amarelos consumiram menos alimentos processados, com 9,2% das calorias (IC95% 7,2-11,1) enquanto os demais consumiram aproximadamente 13%. Ultraprocessados foram menos consumidos por pretos [16,6% (IC95% 15,6-17,6)] e pardos [16,6% (IC95% 16,2-17,1)], e o maior consumo ocorreu entre brancos [20,1% (IC95% 19,6-20,6)] e amarelos [24,5% (IC95% 20,0-29,1)]. O ajuste dos modelos reduziu a magnitude das diferenças entre as categorias de raça/cor da pele. A diferença entre pretos e pardos em relação aos brancos diminuiu, de 3 pontos percentuais (pp), para 1,2 pp no consumo de alimentos in natura/minimamente processados e as maiores diferenças remanescentes foram no consumo de arroz e feijão, com maior percentual na alimentação de pretos e pardos. A participação de alimentos processados permaneceu aproximadamente 4 pp menor para amarelos. O consumo de ultraprocessados diminuiu aproximadamente 2 pp para brancos e amarelos; por outro lado, aumentou 1 pp no consumo de pretos, pardos e indígenas. CONCLUSÃO Diferenças no consumo alimentar segundo raça/cor da pele foram encontradas e são influenciadas por condições socioeconômicas e demográficas.

Geographical distribution of nutritional status of adolescents in a Brazilian city in the early years of the pandemic / Distribuição espacial do estado nutricional de adolescentes de um município brasileiro nos anos iniciais da pandemia

ABSTRACT Objective This study aims to build geographic models related to the nutritional status of adolescents and describe territories regarding the prevalence of malnutrition, overweight, and obesity, in order to spatially represent how the nutritional status of adolescents is distributed in the city. Methods Using geocoding techniques, graphic models were built using data from the SISVAN platform, as well as the addresses and nutritional status of adolescents aged 10 to 19 years in the municipality of Divinópolis, in the state of Minas Gerais (Brazil), between 2020 and 2021. Results There was a prevalence of 34% of obesity and overweight in the 2020 and 2021 samples. The graphical models showed that there is no specific pattern of points for the spread of nutritional diagnoses, but it was possible to identify areas of heat and places with a higher concentration of overweight. Underweight had a homogeneous spread and did not stand out in the formation of profiles. Conclusion Geographic tools with the adolescents' nutritional profile were successfully modeled, which have the potential to contribute to better health indicator management in the assessed territory, even with the limitations of the study.

RESUMO Objetivo Este trabalho tem como objetivo construir modelos geográficos relativos ao perfil nutricional de adolescentes e descrever territórios quanto à prevalência de déficit de peso e excesso de peso, de modo a representar espacialmente como o diagnóstico nutricional de adolescentes está distribuído na área estudada. Métodos Através da técnica de geocodificação foram construídos modelos gráficos utilizando a plataforma SISVAN, os endereços e o estado nutricional de adolescentes de 10 a 19 anos do município de Divinópolis, Minas Gerais, nos anos de 2020 e 2021. Resultados Houve prevalência de 34% de excesso de peso na amostra de 2020 e 2021. Os modelos gráficos mostraram que não há um padrão específico de pontos de propagação dos diagnósticos nutricionais, porém foi possível identificar áreas de calor e locais de maior concentração de excesso de peso. O déficit de peso teve um espalhamento homogêneo e não se destacou na formação de perfis. Conclusão Foi possível modelar ferramentas geográficas com o perfil nutricional dos adolescentes, as quais têm potencial de contribuir para a melhor gestão de indicadores de saúde no território avaliado, mesmo com as limitações do estudo.

Environmental exposure to perchlorate, nitrate, and thiocyanate in relation to chronic kidney disease in the general US population, NHANES 2005-2016 / 中华医学杂志(英文版)

BACKGROUND@#Few studies have explored the impact of perchlorate, nitrate, and thiocyanate (PNT) on kidney function. This study aimed to evaluate the association of urinary levels of PNT with renal function as well as the prevalence of chronic kidney disease (CKD) among the general population in the United States.@*METHODS@#This analysis included data from 13,373 adults (≥20 years) from the National Health and Nutrition Examination Survey 2005 to 2016. We used multivariable linear and logistic regression, to explore the associations of urinary PNT with kidney function. Restricted cubic splines were used to assess the potentially non-linear relationships between PNT exposure and outcomes.@*RESULTS@#After traditional creatinine adjustment, perchlorate (P-traditional) was positively associated with estimated glomerular filtration rate (eGFR) (adjusted β: 2.75; 95% confidence interval [CI]: 2.25 to 3.26; P  < 0.001), and negatively associated with urinary albumin-to-creatinine ratio (ACR) (adjusted β: -0.05; 95% CI: -0.07 to -0.02; P  = 0.001) in adjusted models. After both traditional and covariate-adjusted creatinine adjustment, urinary nitrate and thiocyanate were positively associated with eGFR (all P values <0.05), and negatively associated with ACR (all P values <0.05); higher nitrate or thiocyanate was associated with a lower risk of CKD (all P values <0.001). Moreover, there were L-shaped non-linear associations between nitrate, thiocyanate, and outcomes. In the adjusted models, for quartiles of PNT, statistically significant dose-response associations were observed in most relationships. Most results were consistent in the stratified and sensitivity analyses.@*CONCLUSIONS@#Exposures to PNT might be associated with kidney function, indicating a potential beneficial effect of environmental PNT exposure (especially nitrate and thiocyanate) on the human kidney.

Relationship between cadmium exposure and pulmonary function level and chronic obstructive pulmonary disease / 中华劳动卫生职业病杂志

Objective: To analyze the levels and distribution characteristics of blood cadmium and urinary cadmium in American adults, to analyze the relationship between blood cadmium and urinary cadmium and pulmonary function dose response, and to explore the effect of this index on the risk of chronic obstructive pulmonary disease. Methods: In March 2022, 3785 patients from 2007 to 2012 in NHANES database were selected as the subjects. Collect demography data such as gender and age, and test data such as lung function, blood cadmium concentration and Urine cadimium concentration. The relationship between blood and urine cadmium levels and lung function and pulmonary function and chronic obstructive pulmonary diease (COPD) was analyzed by Mann-Whitney U test or Kruskal-Wallis H test, multivariate linear regression and restricted cubic spline method. Results: The geometric mean of blood cadmium and urine cadmium in American adults was 0.37 g/L and 0.28 g/L, FEV(1) and FEV(1)/FVC among different cadmium exposure groups was statistically significant, and there was a negative linear dose-response relationship between serum Cd and urine Cd concentrations and FEV(1)/FVC levels (P(overall)<0.001, P(non-linear)=0.152; P(overall)<0.001, P(non-linear)=0.926). Compared with the lowest quartile concentration (Q1), the highest quartile blood cadmium concentration (Q4) (OR=1.934, P(trend)=0.000) and urinary cadmium concentration (OR=1.683, P(trend)=0.000) may increased the risk of chronic obstructive pulmonary disease. Conclusion: There is a negative correlation between blood cadmium, urinary cadmium levels and lung function in American adults, and cadmium may increase the risk of chronic obstructive pulmonary disease.

The association between heavy metal exposure and erectile dysfunction in the United States / 亚洲男科学杂志(英文版)

Literature regarding the impacts of heavy metal exposure on erectile dysfunction (ED) is scarce. We aimed to evaluate the correlation between 10 urinary metals and ED in a large, nationally representative adult male sample. The dataset was extracted from the National Health and Nutrition Examination Survey (NHANES) during the period of 2001-2002 and 2003-2004. Weighted proportions and multivariable logistic regression analysis adjusted for confounding variables were utilized to determine the relationship between metal exposure and ED. Weighted quantile sum (WQS) regression was utilized to evaluate the impact of a mixture of urinary metals on ED. A total of 1328 participants were included in our study. In multivariable logistic regression analysis, cobalt (Co) and antimony (Sb) were positively associated with ED (odds ratio [OR]: 1.36, 95% confidence interval [CI]: 1.10-1.73, P = 0.020; and OR: 1.41, 95% CI: 1.12-1.77, P = 0.018, respectively) after full adjustment. Men in tertile 4 for Co (OR: 1.49, 95% CI: 1.02-2.41, P for trend = 0.012) and Sb (OR: 1.53, 95% CI: 1.08-2.40, P for trend = 0.041) had significantly higher odds of ED than those in tertile 1. Furthermore, the WQS index was significantly linked with increased odds of ED after full adjustment (OR: 1.31, 95% CI: 1.04-1.72, P < 0.05). Our study expanded on previous literature indicating the possible role of heavy metal exposure in the etiology of ED. The evaluation of heavy metal exposure should be included in the risk assessment of ED.

Hábitos de consumo de alimentos y bebidas en hogares argentinos según presencia de adultos mayores y nivel de ingreso / Food and beverage consumption habits in Argentinean households by presence of elderly members and income level

INTRODUCCIÓN: Los patrones alimentarios de los adultos mayores son un aspecto clave en la calidad de vida y la morbimortalidad. Los datos al respecto son escasos en la población argentina. El objetivo fue evaluar los hábitos de consumo de alimentos y bebidas en hogares argentinos según presencia de adultos mayores y nivel de ingreso. MÉTODOS: Se realizó un estudio observacional, descriptivo y de corte transversal a partir de la Encuesta Nacional de Gastos de los Hogares 2017-2018. Se calculó el consumo aparente de alimentos (g o ml) por adulto equivalente por día en tres tipos de hogares según la presencia de adultos >60 años: a) sin adultos mayores (SAM), b) multigeneracionales con adultos mayores (MAM) y c) unigeneracionales de adultos mayores (UAM), estratificados según nivel de ingresos. RESULTADOS: De los 21 254 hogares que registraron compra de alimentos y bebidas en la semana de la encuesta, hubo 64% SAM, 19% MAM y 17% UAM. Los hogares UAM presentaron mayor consumo aparente de alimentos y bebidas, especialmente hortalizas y frutas, legumbres, leche, yogur y quesos, huevos, aceite, frutas secas y semillas, y alimentos de consumo opcional según las guías alimentarias nacionales. El consumo fue creciente a medida que aumentaban los ingresos del hogar. DISCUSIÓN: El análisis evidenció diferencias en los hábitos alimentarios según composición del hogar y nivel de ingreso, y permite planificar estrategias para mejorar la calidad de vida de un grupo poblacional en aumento.

Inquérito Nacional de Alimentação de 2017-2018 no Brasil: implementação e análise / National Food Survey 2017-2018 in Brazil: implementation and analisys

A avaliação do consumo alimentar da população brasileira é uma preocupação de longa data. Os primeiros dados de amplitude nacional sobre alimentação dos brasileiros foram publicados a partir do Estudo Nacional de Despesa Familiar (ENDEF) entre 1974-1975. Por serem baseados na pesagem dos alimentos consumidos nos domicílios durante uma semana, os dados retratavam o consumo do domicílio, ou seja, não captavam o consumo individual. A partir de então, os dados da Pesquisa de Orçamento Familiar (POF) vem sendo usados para a avaliação da alimentação no Brasil. As primeiras POF realizadas em 1987-1988, 1995-1996 e em 2002-2003, permitiam estimar o consumo a partir da aquisição domiciliar de alimentos no período de uma semana. Ou seja, somente os alimentos que foram adquiridos e que passaram pelo domicílio são analisados. Os dados das refeições realizadas fora do domicílio não são considerados, portanto, não permitem avaliar o consumo individual em sua totalidade. A fim de solucionar essa limitação, as duas últimas POF realizadas em 2008-2009 e 2017-2018, adicionaram informações do consumo alimentar individual em uma subamostra da pesquisa. Esses dados permitem fazer avaliações a nível individual, caracterizando melhor o consumo de alimentos por sexo, faixa etária, e outras variáveis sociodemográficas. Esta tese apresenta as etapas de desenvolvimento do bloco de consumo alimentar pessoal da POF de 2017-2018, aqui referido como Inquérito Nacional de Alimentação (INA) , realizado pelo IBGE. O objetivo deste trabalho é documentar o processo de desenvolvimento dos instrumentos, da base de dados e de adequações para comparações temporais do INA 2017-2018 com o INA 2008-2009, bem como apresentar os alimentos mais frequentemente consumidos nos dois inquéritos e a evolução do consumo na última década. Para o INA 2017-2018, foram coletados dois recordatórios de 24 horas em dias não consecutivos de 46.164 indivíduos com 10 anos ou mais de idade, representando uma subamostra de 34,7% da amostra geral da POF. Todas as alterações metodológicas sofridas de um inquérito para o outro, como: mudança do instrumento de coleta e da tabela de composição dos alimentos, atualização da base de dados, adições de novas variáveis como itens de adição e ocasiões de consumo estão descritas neste trabalho. As mudanças na coleta de dados aprimoraram o instrumento que apresentou menor sub-relato no inquérito mais recente. A mudança na tabela de composição para a Tabela Brasileira de Composição de Alimentos (TBCA), em reanálise dos dados de 2008-2009 representou mudanças de estimativas de energia, macronutrientes e minerais menores do que 15%, com exceção das gorduras trans e selênio, com médias 40% e 52% menores na TBCA.Na comparação dos dois inquéritos constatou-se que embora a população brasileira permaneça comendo arroz, feijão, café, pão, carne bovina e legumes como os seis principais itens da alimentação, houve redução na frequência do consumo de arroz, feijão, carne bovina, pães, frutas, laticínios, carnes processadas e refrigerantes e aumento no consumo de sanduíches, independente de sexo, idade e renda. As duas maiores mudanças foram relativas à redução do feijão e aumento de sanduíches, que apresentou estimativa de mais de 4 vezes mais chance de aumento nas brasileiras idosas. Ainda, a tendência de aumento do consumo de sanduíches foi três vezes maior no menor quartil de renda comparado ao maior. Tendência positiva foi a redução de refrigerantes em todas as classes de renda. As mudanças observadas na alimentação do brasileiro nesse período de 10 anos são consistentes com a política de redução de bebidas adoçadas e com a redução da renda familiar no período. Os resultados sinalizam piora na alimentação do brasileiro.

The evaluation of the food consumption of the Brazilian population is a long-standing concern. The first comprehensive data on the diet of Brazilians were those from the National Study of Family Expenditure (ENDEF) between 1974-1975. The survey captures the data of one week family consumption, using weighing method. Since then, data from the Family Budget Survey (POF) have been used to assess diet in Brazil. The first POF was carried out in1987-1988, followed by 1995-1996 and 2002-2003. Estimation of consumption is based on household purchases in a period of one week. Thus, meals eaten away from home are not considered, and therefore, do not allow the assessment of individual consumption.. In order to solve this limitation, the last two POF carried out in 2008-2009 and 2017-2018included a new block of data that collected information from individual food consumption in a subsample of the survey. These data allow making individual-level estimates, characterizing food consumption by sex, age group, and other sociodemographic variables. Development and analytical strategies of the 2017-2018 National Dietary Survey (NDS) included in the Family Budget Survey is shown in this thesis. Thus, the objective of this work is to document the process of selection and adaptation of the instruments, the food database for energy and nutrient analysis and the necessary harmonization with previous NDS of 2008-2009. Also, the foods most frequently consumed in the two surveys and the evolution of the consumption in the last decade was analyzed. For NDS 2017-2018, two 24-hour recalls were collected on non-consecutive days of 46,164 with 10 years of age or older, representing a subsample of 34.7% of the general POF. All methodological changes from one survey to the other, such as: instrument to collect data, food composition databases, new variables added are presented. In addition, results of change in the foods most frequently consumed by the population is presented. Changes in data collection improved the instrument that had the lowest underreporting in the most recent survey. The change in the composition table for Brazilian Food Composition Table (TBCA), in reanalysis of the 2008-2009 data, showed changes in energy, macronutrient and mineral estimates of less than 15%, with the exception of trans fats and selenium, with average changes of 40% and 52% lower in the TBCA. Comparing the two surveys, it was found that although the results show that the Brazilian population continues to eat rice, beans, coffee, bread, beef and vegetables as the six main food items, there was a reduction in the frequency of consumption of rice, beans, beef, breads, fruits, dairy products, processed meats and soft drinks and an increase in the consumption of sandwiches, regardless of gender, age and income. The two biggest changes were related to the reduction of beans and the increase of sandwiches, which was estimated to be more than 4 times more likely to increase in elderly Brazilians. A positive trend was the reduction of soft drinks in all income classes. The changes observed in the diet of Brazilians in this 10-year period are consistent with the policy of reducing sweetened beverages and with the reduction of family income in the period. The results indicate a worsening in the Brazilian diet.

Perfil nutricional e sociodemográfico de indivíduos brasileiros que seguem dietas especiais: II Inquérito Nacional de Alimentação: 2017 - 2018 / Nutritional and sociodemographic profile of the brazilian population on special diets: II National Food Survey: 2017 - 2018

A adoção de uma alimentação saudável auxilia no controle e mortalidade por Doenças Crônicas não Transmissíveis (DCNT). Uma alimentação mais saudável pode ser alcançada pela prática de dietas especiais, que podem ser adotadas devido ao diagnóstico de algumas doenças. Conhecer o percentual de quem faz dietas especiais pode ser útil para o monitoramento do cuidado e enfrentamento das DCNT no Brasil. Assim, o presente trabalho objetivou estimar a prevalência do uso de dieta especial na população brasileira segundo tipos de dieta, variáveis sociodemográficas e estado nutricional. Trata-se de um estudo transversal e descritivo utilizando dados do Inquérito Nacional de Alimentação (INA) 2017/2018 (n=46.164 indivíduos com 10 anos ou mais de idade). Os participantes foram questionados se estavam fazendo alguma dieta especial, e para qual finalidade. Foram obtidas as prevalências de prática de dietas de acordo com características sociodemográficas, estado nutricional, uso de sal, açúcar e adoçante de adição, e suplementos nutricionais. Para o cálculo das estimativas, foi utilizado o Software R versão 4.1.0 considerando a complexidade da amostra e os fatores de expansão. Entre a população estudada (n=46.164 indivíduos), 14,3% afirmaram realizar algum tipo de dieta. Quando comparado por sexo, a prevalência foi maior entre as mulheres (17,8%) do que entre os homens (9,6%), sendo a dieta para pressão alta mais prevalente nos homens (3,7%) e a dieta para emagrecer mais prevalente nas mulheres (7,4%). O uso de dietas foi maior entre idosos (homens: 22,4%; mulheres: 31,2%) e obesos (homens: 13,2%; mulheres: 26,0%), para todos os tipos de dietas, e menor entre indivíduos de menor renda (homens: 4,3% vs. 20,4% maior renda; mulheres: 10% vs. 26,1% maior renda) e menor escolaridade (homens: 6,7% vs. 23,6% com maior escolaridade; mulheres: 11,9% vs. 23,9% com maior escolaridade). Os indivíduos que relataram realizar dieta, comparados com os que não relataram, apresentaram menor prevalência de consumo de sal (homens: 12,0% vs. 15,5%; mulheres: 9,6% vs. 12,6%) e açúcar de adição (homens: 53,1% vs. 85,4%; mulheres: 51,1% vs. 81,9%) e maior prevalência de consumo de suplementos nutricionais (homens: 32,2% vs. 13,7%; mulheres: 38,6% vs. 19,2%). O uso de dietas foi maior entre as mulheres, idosos e obesos, e menor entre indivíduos de menor renda e menor escolaridade para todos os tipos de dieta. Embora as DCNTs sejam mais frequentes entre os indivíduos de menor renda e menor escolaridade, o uso de dietas especiais foi menos frequente neste grupo.

The adoption of a healthy diet helps in the control and mortality from Chronic Non-Communicable Diseases (NCDs). A healthier diet can be achieved by the practice of special diets, which can be adopted due to the diagnosis of some diseases. Knowing the percentage of those on special diets can be useful for monitoring the care and coping with NCDs in Brazil. Thus, the present study aimed to estimate the prevalence of special diet use in the Brazilian population according to types of diet, sociodemographic variables and nutritional status. This is a cross-sectional and descriptive study using data from the National Food Survey (INA) 2017/2018 (n=46,164 individuals aged 10 years and over). Participants were asked if they were on a special diet, and for what purpose. Prevalence of diet practices were obtained according to sociodemographic characteristics, nutritional status, use of salt, sugar and added sweeteners, and nutritional supplements. To calculate the estimates, Software R version 4.1.0 was used, considering the complexity of the sample and the expansion factors. Among the population studied (n=46,164 individuals), 14.3% stated that they were on some type of diet. When compared by sex, the prevalence was higher among women (17.8%) than among men (9.6%), with the diet for high blood pressure being more prevalent in men (3.7%) and the diet for weight loss more prevalent in women (7.4%). Diet use was higher among the elderly (men: 22.4%; women: 31.2%) and obese (men: 13.2%; women: 26.0%), for all types of diets, and lower among individuals with lower income (men: 4.3% vs. 20.4% higher income; women: 10% vs. 26.1% higher income) and less educated (men: 6.7% vs. 23.6% with higher education; women: 11.9% vs. 23.9% with higher education). Individuals who reported dieting, compared with those who did not, had a lower prevalence of salt consumption (men: 12.0% vs. 15.5%; women: 9.6% vs. 12.6%) and sugar addiction (men: 53.1% vs. 85.4%; women: 51.1% vs. 81.9%) and a higher prevalence of consumption of nutritional supplements (men: 32.2% vs. 13.7% ; women: 38.6% vs. 19.2%). The use of diets was higher among women, elderly and obese, and lower among individuals with lower income and lower education for all types of diet. Although CNCDs are more frequent among individuals with lower income and lower education, the use of special diets was less frequent in this group.

Relação do risco nutricional e perfil glicêmico no desfecho de pacientes críticos / Relationship of nutritional risk and glycemic profile in the outcome of critically ill patients

Em pacientes críticos o risco nutricional e a hiperglicemia associam-se ao aumento da incidência de desfechos desfavoráveis. Objetivo: Avaliar a relação do risco nutricional pelo Nutrition Risk in Critically III, versão modificada (mNUTRIC) e perfil glicêmico nos desfechos de alta, óbito e tempo de internação de pacientes críticos e verificar o impacto das ferramentas Acute Physiology and Chronic Health Disease Classification System II (APACHE II) e do Sepsis-Related Organ Failure Assessment (SOFA) nesses desfechos. Método: Estudo longitudinal prospectivo desenvolvido em Unidade de Terapia Intensiva (UTI). Foram incluídos adultos, com tempo ≥ 48 horas de internação e com registro mínimo de duas aferições glicêmicas. Excluíram-se pacientes em cuidados paliativos, readmitidos nas UTI e gestantes. O teste Exato de Fisher e Shapiro Wilk foram utilizados para avaliar as variáveis categóricas e contínuas, respectivamente. Posteriormente, utilizou-se o teste de Mann-Whitney ou t-Student não pareado. Realizou-se análise de regressão logística e linear. O nível de significância adotado foi de 5%. Resultados: Ao avaliar 35 pacientes, 45,7% apresentaram alto risco nutricional. Foi observado associação do risco nutricional com os desfechos de alta e óbito; o SOFA associou-se ao óbito e tempo de internação. O incremento de 1 ponto no escore do SOFA aumentou a chance de óbito em 83% e tempo maior de internação em 0,49 dias. O perfil glicêmico e APACHE II não se associou aos desfechos. Conclusão: o escore SOFA foi o instrumento que apresentou associações significativas com o desfecho do óbito e maior tempo de internação de pacientes críticos

In critically ill patients, nutritional risk and hyperglycemia are associated with an increased incidence of unfavorable outcomes. Objective: To evaluate the relationship of nutritional risk by the Nutrition Risk in Critically III, modified version (mNUTRIC) and glycemic profile in the outcomes of discharge, death and length of stay in critically ill patients and to verify the impact of the Acute Physiology and Chronic Health Disease Classification System II (APACHE II) and the Sepsis-Related Organ Failure Assessment (SOFA) tools on these outcomes. Method: Prospective longitudinal study developed in an Intensive Care Unit (ICU). Adults were included, with ≥ 48 hours of hospitalization and with a minimum record of two blood glucose measurements. Patients in palliative care, readmitted to ICU and pregnant women were excluded. Fisher's Exact test and Shapiro Wilk test were used to evaluate categorical and continuous variables, respectively. Subsequently, the Mann-Whitney or unpaired t-Student test was used. Logistic and linear regression analysis was performed. The significance level adopted was 5%. Results: When evaluating 35 patients, 45.7% were at high nutritional risk. An association was observed between nutritional risk and discharge and death outcomes; SOFA was associated with death and length of hospital stay. The increment of 1 point in the SOFA score increased the chance of death by 83% and a longer hospital stay by 0.49 days. Glycemic profile and APACHE II were not associated with outcomes. Conclusion: the SOFA score was the instrument that showed significant associations with the outcome of death and longer hospital stay in critically ill patients

Análisis del consumo, utilización y aprovechamiento de frutas y verduras entre los años 2019 y 2021 / Analysis of consumption, use and utilization of fruits and vegetables between 2019 and 2021

En 2021 se conmemoró el Año Internacional de las Frutas y Verduras (FyV). Estos alimentos cumplen un rol indispensable en la dieta, sin embargo, un amplio sector de la población no las consume en la variedad y cantidad recomendadas. A esto se suma la problemática de las pérdidas y desperdicios de alimentos, situación que trae consigo un impacto negativo a nivel social, ambiental y económico. El objetivo del presente artículo fue analizar el consumo, utilización y aprovechamiento de FyV desde las perspectivas de salud y sostenibilidad. Para esto, se realizaron cuatro encuestas entre 2019 y 2021 que evaluaron diferentes dimensiones relacionadas con estos alimentos: adecuación del consumo, variedades consumidas, criterios de calidad de FyV apreciados por los consumidores y prácticas de sostenibilidad y consumo responsable. Sólo el 19% de los encuestados presentó consumos adecuados de FyV (5 o más porciones diarias). La variedad de frutas consumidas es menor que la de hortalizas, concentrándose en tres de ellas: manzana, banana y naranja. Los principales factores identificados como limitantes del consumo de FyV fueron el precio, la elevada perecibilidad de estos alimentos y la preferencia hacia otros productos. En relación a las prácticas de alimentación sostenible y los principales criterios de calidad valorados por los consumidores se observó un bajo aprovechamiento de partes comestibles de frutas o verduras, menos del 27% de los encuestados consume la fruta con cáscara, y un mayor desaprovechamiento de partes comestibles de verduras, dónde el 64% de los encuestados tira partes como tallos u hojas, aún cuando existen vías de aprovechamiento con fines no alimenticios. Por último, el factor de calidad más apreciado por los consumidores es la apariencia (30%), el valor nutricional no fue un parámetro de gran valoración (6%)(AU).

In 2021, the International Year of Fruits and Vegetables (FyV) was commemorated. These foods play an essential role in the diet; however, a large sector of the population does not consume them in the recommended variety and quantity. Added to this is the problem of food losses and waste, a situation that brings about a negative impact at a social, environmental and economic level. The objective of this article was to analyze the consumption, use and utilization of F&V from the perspectives of health and sustainability. For achiving this, four surveys were carried out between 2019 and 2021 that evaluated different dimensions: adequacy of consumption, varieties consumed, F&V quality criteria appreciated by consumers, and sustainability practices and responsible consumption. Only 19% of those surveyed presented adequate consumption of F&V (5 or more daily servings). The variety of fruits consumed is less than that of vegetables, concentrating on three of them: apple, banana and orange. The main factors limiting the consumption of F&V were the price, the high perishability of these foods and the preference for other products. In relation to sustainable eating practices and the main quality criteria valued by consumers, a low use of edible parts of fruits or vegetables was observed, less than 27% of respondents consume fruit with peel, and a greater waste of edible parts of vegetables, where 64% of respondents throw away parts such as stems or leaves, even when there are ways of using them for non-food purposes. Finally, the quality factor most appreciated by consumers is appearance (30%), nutritional value was not a highly valued parameter (6%)(AU).

Relationship between pesticide exposure and lipid metabolism in population / 中华劳动卫生职业病杂志

Objective: To investigate the effect of pesticides and herbicides on lipid metabolism. Methods: In November 2020, Based on the data of the national health and Nutrition Survey (NHANES) (2011-2014) , select the population aged 20~65 who have demographic information, pesticide use and data of four lipid metabolism indicators [total cholesterol (TC) , triglyceride (TG) , high density lipoprotein cholesterol (HDLC) and low density lipoprotein cholesterol (LDLC) ] (n=3039) . The subjects were divided into insecticide group (320 people) and non insecticide group (2719) according to the use of insecticides, and herbicide group (156 people) and non herbicide group according to the use of herbicides. Results: Among the 3039 subjects, the males and female were 1509 (49.7%) and 1530 (50.3%) respectively. The males age was (39.7±12.0) years and the females age was (40.2±12.0) years The concentration of HDLC in the NHANES (55.4±15.0) mg/dl was lower than that of (58.2±14.2) mg/dL in the non herbicide group (P<0.05) (b=-0.044, P<0.05) . The results showed that the use of herbicides was related to the decrease of HDLC and the increase of LDLC and LDLC/HDLC in female population (b=-0.050, 0.062, 0.067, all P<0.05) . Conclusion: Herbicide exposure can cause the change of lipid metabolism, and the effect on female population is more obvious.

Correlation analysis between children and adolescents watching food TV advertising and fast food consumption / 中华预防医学杂志

Based on the open data of China Health and Nutrition Survey (CHNS), 249 children, adolescents and 249 heads of families who completed two rounds of surveys in 2011 and 2015 were selected in this study. According to the fast food consumption of children and adolescents, they were divided into fast food consumption group and non-fast food consumption group. Logistic regression model was used to analyze the relationship between children and adolescents watching Food TV advertising and fast food consumption. After adjusting relevant factors, the results showed that children and adolescents requiring their parents to buy food in TV advertisements (OR=3.122, P=0.001), parents buying food for their children in TV advertisements (OR=4.717, P=0.036), children and adolescents buying food in TV advertisements themselves (OR=3.728, P=0.041), children and adolescents' preference for food in TV advertisements (OR=2.946, P=0.044) and the frequency of children and adolescents reported by their parents asking their parents to buy food in TV advertisements (OR=3.113, P=0.002) were associated with children and adolescents' fast food consumption.

Waist Circumference of the Elderly over 65 Years Old in China Increased Gradually from 1993 to 2015: A Cohort Study / 生物医学与环境科学（英文）

Objective@#This study aimed to analyze the temporal trends and characteristics associated with waist circumference (WC) among elderly Chinese people.@*Methods@#We used data from 3,096 adults ≥ 65 years who participated in the China Health and Nutrition Survey (CHNS), an ongoing cohort study, between 1993 and 2015. We used longitudinal quantile regression models to explore the temporal trends and characteristics associated with WC.@*Results@#WC increased gradually among the elderly Chinese population during the survey. The WC curves shifted to the right with wider distributions and lower peaks in men and women. All WC percentile curves shifted upward with similar growth rates in the 25th, 50th, and 75th percentiles. The WC means increased from 78 cm to 86 cm during the 22 years of our study. WC significantly increased with age and body mass index and decreased with physical activity (PA). These associations were stronger in the higher percentiles than in the lower percentiles.@*Conclusions@#WC is rising among Chinese adults ≥ 65 years. Factors affecting WC in elderly people may have different effects on different percentiles of the WC distribution, and PA was the most important protective factor in the higher percentiles of the WC distribution. Thus, different interventional strategies are needed.

Memorization of messages, satisfaction, and feasibility of a nutritional intervention using a mobile text messaging app among adolescents / Memorização de mensagens, satisfação e usabilidade de intervenção nutricional via aplicativo de envio de mensagens entre adolescentes

ABSTRACT Objective This study aimed to evaluate the memorization of messages that promote healthy eating, as well as satisfaction and feasibility of a nutritional intervention using a mobile text messaging app aimed at adolescents from public schools in the Federal District, Brazil. Methods The messages sent addressed aspects of healthy eating based on the Dietary Guidelines for the Brazilian Population. A self-reported questionnaire was applied with 94 students to assess the memorization of the messages received during the nutritional intervention, the level of satisfaction with the intervention, whether the messages were read and shared, the frequency of reading, and what was learned from the intervention. The association of memorization with satisfaction and with the frequency of reading the messages was also investigated. Results About 48% of participants reported remembering at least one message; 77.7% showed high ranges of satisfaction; 54.3% always read the messages; 66.0% did not share messages with other people. Most of the students reported positive learning or good impressions about the intervention. An association was found between memorization and satisfaction with the intervention (p=0.002), as well as between reading and memorization (p=0.005). Conclusion Although the memorization of the healthy eating messages sent in the nutritional intervention was less than expected, a great satisfaction and high frequency of reading the messages were reported by adolescents. Future studies should investigate the permanence of the results of long-term nutrition intervention, the main influencers of memorization, and how to improve it.

RESUMO Objetivo Este estudo teve como objetivo avaliar a memorização de mensagens de promoção de alimentação adequada e saudável, a satisfação e a usabilidade de uma intervenção nutricional via aplicativo direcionada para adolescentes de escolas públicas do Distrito Federal. Métodos As mensagens enviadas abordavam aspectos sobre alimentação adequada e saudável com base no Guia Alimentar para a População Brasileira. Foi aplicado um questionário de autopreenchimento a 94 estudantes para avaliar a memorização das mensagens recebidas durante a intervenção nutricional, o nível de satisfação com a intervenção, se as mensagens eram lidas e compartilhadas, a frequência de leitura e quais foram os aprendizados decorrentes da intervenção. Investigou-se ainda a associação entre a memorização, a satisfação e a frequência de leitura das mensagens. Resultados Cerca de 48% dos participantes referiram lembrar de pelo menos uma mensagem da intervenção; 77,7% se mostraram satisfeitos com o estudo; 54,3% sempre liam as mensagens que recebiam e 66% não compartilhava as mensagens com outras pessoas. A maioria relatou aprendizados ou impressões positivas sobre a intervenção. Foi encontrada uma associação entre a memorização das mensagens e a satisfação com o estudo (p=0,002), bem como entre a leitura e a memorização das mensagens (p=0,005). Conclusão Apesar de a memorização das mensagens enviadas na intervenção nutricional ter sido aquém do esperado, foi referida grande satisfação e alta frequência de leitura pelos adolescentes. Futuros estudos devem investigar a permanência dos resultados de intervenções nutricionais a longo prazo, os principais influenciadores da memorização e como melhorá-la.
