RESUMEN

PURPOSE: Studies of migrants can improve understanding of the environmental influence on the risk of chronic diseases. In continental countries, internal migration has been associated with changes in diet and health status. The objective of this study is to assess differences in diet quality and the cardiometabolic risk profile between migrants and the host population. METHODS: A cross-sectional, population-based study was conducted in the city of São Paulo. The study population included internal migrants, defined as individuals born outside São Paulo city who had lived in the city for ten years or longer. The final population (n = 537) was divided into three groups: natives of São Paulo (45.5%), migrants from the Southeast (26.9%) and migrants from the Northeast (27.5%). The joint interim statement consensus criteria were used for diagnosing MetSyn. Diet quality was estimated using the revised version of the Brazilian Healthy Eating Index (BHEI-R). Comparisons between the data of BHEI-R, cardiometabolic risk factors and MetSyn in migrants and natives were performed using generalized linear models adjusted for confounding factors, respectively. RESULTS: Southeastern and Northeastern migrants younger than 60 years had a higher average of for whole fruit and oil components, respectively. Northeastern migrants older than 60 years had higher systolic and diastolic blood pressure, atherogenic ratio concentrations, lower HDL-C and were more likely to present metabolic syndrome compared to those born in São Paulo of the same age group. CONCLUSION: Native and internal migrants from Brazil resident in São Paulo exhibited differences in diet quality and cardiometabolic risk factors.

RESUMEN

BACKGROUND: This study aimed to identify novel plasma metabolic signatures with possible clinical relevance during the aging process. A biochemical quantitative phenotyping platform, based on targeted electrospray ionization tandem mass spectrometry technology, was used for the identification of any eventual perturbed biochemical pathway by the aging process in prospectively collected peripheral blood plasma from 166 individuals representing the population of São Paulo city, Brazil. RESULTS: Indoleamine 2,3-dioxygenase (IDO) activity (Kyn/Trp) was significantly elevated with age, and among metabolites most associated with elevations in IDO, one of the strongest correlations was with arginase (Orn/Arg), which could also facilitate the senescence process of the immune system. Hyperactivity of IDO was also found to correlate with increased blood concentrations of medium-chain acylcarnitines, suggesting that deficiencies in beta-oxidation may also be involved in the immunosenescence process. Finally, our study provided evidence that the systemic methylation status was significantly increased and positively correlated to IDO activity. CONCLUSIONS: In the present article, besides identifying elevated IDO activity exhibiting striking parallel association with the aging process, we additionally identified increased arginase activity as an underlying biochemical disturbance closely following elevations in IDO. Our findings support interventions to reduce IDO or arginase activities in an attempt to preserve the functionality of the immune system, including modulation of myeloid-derived suppressor cells (MDSCs), T cells, macrophages, and dendritic cells' function, in old individuals/patients.

RESUMEN

Chronic kidney disease (CKD) is a serious public health problem and its prevalence is growing in many countries, often related to issues resulting from the lifestyle in growing economies and the population's life expectancy. Nutritional therapy is a beneficial but still neglected strategy for preventing CKD and delaying disease progression. The aim of this study was to assess the association of dietary patterns with CKD development and progression. Observational studies conducted in adult humans and the correlation between the adopted dietary pattern and prevalent and incident cases of CKD were assessed. A significant association was observed between unhealthy dietary patterns and an increased risk of developing or worsening CKD, as well as an adverse effect. Whereas healthy eating patterns characterized by the consumption of fruit, vegetables and dietary fibre showed nephroprotective outcomes.

RESUMEN

PURPOSE: A structural equation model (SEM) was used to test multiple and simultaneous relationships between socio-demographic factors, dietary patterns, biochemical levels of folate, vitamin B12, docosahexaenoic acid (DHA), and its effects on homocysteine (Hcy) level. METHODS: Socio-demographic and lifestyle characteristics, blood sample, anthropometric measurements, and a food-frequency questionnaire (FFQ) were obtained from 281 individuals of ISA-Capital study (Sao Paulo, Brazil). The dietary patterns (DP) were estimated using factor analysis with principal component's estimation based on the frequency of daily intake derived from the 38-item FFQ. The SEM considered a theoretical model where the DP were expected to be directly associated with Hcy level, and indirectly via biochemical levels of folate, vitamin B12, and DHA. The variables sex, age, ethnicity, and MTHFR C677T polymorphism were included in the model. RESULTS: The Prudent DP (- 0.12, p = 0.04) had a negative effect, while MTHFR C677T polymorphism (0.16, p = 0.01), age (0.22, p < 0.01), and being man (0.16, p = 0.01) had a positive effect on Hcy level. There were no indirect effects of any dietary patterns on Hcy level, neither via folate, vitamin B12, nor DHA. DHA was negatively associated with the Modern DP (- 0.12, p = 0.04) and positively associated with the Prudent DP (0.19, p < 0.01). CONCLUSIONS: The DP mainly composed of fruits and vegetables, natural juices, potato/cassava/cooked cornmeal, fish, and chicken, which was negatively associated with the Hcy level in this population. These findings support the role of a healthy dietary pattern in health outcomes, rather than promoting specific foods or nutrients, for policy-based health promotion strategies.

RESUMEN

BACKGROUND: The Paleolithic diet has been studied in the scope of prevention and control of chronic noncommunicable diseases (CNCD). The objective of this study was to analyze the influence of the Paleolithic diet on the prevention and control of CNCD in humans, specifically on anthropometric markers, through a systematic review with meta-analysis. METHODS: What is the effect of the Paleolithic diet on anthropometric parameters (weight, body mass index and waist circumference) compared to other control diets based on recommendations in adults? We included only randomized studies with humans that used the Paleolithic Diet in the prevention and control of CNCD published in Portuguese, English or Spanish. The search period was until March 2019, in the LILACS, PubMed, Scielo, Science Direct, Medline, Web of Science and Scopus databases. The abstracts were evaluated by two researchers. We found 1224 articles, of which 24 were selected and 11 were included in the meta-analysis. The effect of dietary use on body weight, body mass index and waist circumference was evaluated. RESULTS: The summary of the effect showed a loss of - 3.52 kg in the mean weight (CI 95%: - 5.26; - 1.79; p < 0,001; I2 = 24%) of people who adopted the Paleolithic diet compared to diets based on recommendations. The analysis showed a positive association of adopting the Paleolithic diet in relation to weight loss. The effect was significant on weight, body mass index and waist circumference. CONCLUSION: The Paleolithic diet may assist in controlling weight and waist circumference and in the management of chronic diseases. However, more randomized clinical studies with larger populations and duration are necessary to prove health benefits. TRIAL REGISTRATION: CRD42015027849 .

RESUMEN

PURPOSE: To estimate the prevalence of metabolic syndrome (MetS) and its components in adults and older adults residents of São Paulo, the association of MetS with the glycemic index (GI) and glycemic load (GL) and the foods that contribute to dietary GI and GL in this population. METHODS: Data from 591 adults and older adults participants in the Health Survey of São Paulo were used. This is a cross-sectional, population-based study with a complex multistage sample design of residents in the urban area of the municipality. Dietary consumption data, anthropometric measurements, blood pressure and blood samples were collected. The associations between GI, GL and MetS and its components were tested using logistic regression models, considering the sample design of the study. RESULTS: The prevalence of MetS in the adult and older adults residents of São Paulo was 30.3%. There was no association between GI, GL and MetS. GI and GL were positively associated with low high-density lipoprotein cholesterol (HDL-c), OR = 1.113 (95% CI 1.007-1.230) and OR = 1.019 (95% CI 1.002-1.037), respectively. GL was inversely associated with high blood pressure and this association differed by age group (OR = 0.981; 95% CI 0.964-0.998). Foods that most contributed to dietary GI and GL were sugar, white rice and French bread. CONCLUSIONS: Considering the high prevalence of low HDL-c in the population of São Paulo, GI and GL may contribute to the nutritional therapy of this dyslipidemia. However, findings should be treated with caution, considering several conflicting results between studies.

RESUMEN

The prevalence of non-alcoholic fatty liver disease (NAFLD) is rising, an increase that may be associated with changes in lifestyle such as unhealthy dietary patterns. Although advanced age is a risk factor for NAFLD, no studies reporting this association in the elderly population were found. In the present study, the association between dietary patterns and NAFLD in the elderly was assessed. A study including 229 older adults was conducted. NAFLD diagnosis was defined as individuals whose ultrasound examination disclosed hepatic steatosis at any stage, in the absence of excess intake of alcoholic beverages. Dietary patterns were obtained by principal components analysis. Mean scores and standard errors of each dietary pattern were calculated for the groups with and without NAFLD, and mean scores of the two groups were compared using the Mann-Whitney U test. The prevalence ratios and 95 % CI were estimated for each tertile of the dietary pattern adherence scores using Poisson multiple regression models with robust variance. A total of 103 (45 %) elderly with NAFLD and four dietary patterns were identified: traditional, regional snacks, energy dense and healthy. Mean scores for adherence to the healthy pattern in the groups with and without NAFLD differed. NAFLD was inversely associated with greater adherence to the healthy pattern and directly associated with the regional snacks, after adjustment for confounders. In conclusion, healthy dietary pattern is inversely associated with NAFLD in elderly.

RESUMEN

BACKGROUND: The fatty acid profile is associated with the risk and progression of several diseases, probably via mechanisms including its influence on gene expression. We previously reported a correlation between ECHDC3 upregulation and the severity of acute coronary syndrome. Here, we assessed the relationship of serum fatty acid profile and ECHDC3 expression with the extent of coronary lesion. METHODS: Fifty-nine individuals aged 30 to 74 years and undergoing elective cinecoronariography for the first time were enrolled in the present study. The extent of coronary lesion was assessed by the Friesinger index and patients were classified as without lesion (n = 18), low lesion (n = 17), intermediate lesion (n = 17) and major lesion (n = 7). Serum biochemistry, fatty acid concentration, and ECHDC3 mRNA expression in blood were evaluated. RESULTS: Elevated serum levels of oleic acid and total monounsaturated fatty acids were observed in patients with low and intermediate lesion, when compared to patients without lesion (p < 0.05). ECHDC3 mRNA expression was 1.2 fold higher in patients with low lesion than in patients without lesion (p = 0.020), and 1.8 fold lower in patients with major lesion patients than in patients with low lesion (p = 0.023). CONCLUSION: Increased levels of monounsaturated fatty acids, especially oleic acid, and ECHDC3 upregulation in patients with coronary artery lesion suggests that these are independent factors associated with the initial progression of cardiovascular disease.

RESUMEN

Dietary glycemic index (GI) and glycemic load (GL) are indicators of carbohydrate consumption and widely used in studies evaluating the risk for breast cancer. However, the effect of chemotherapy on these indices has been scarcely studied. The aim of this study was to evaluate dietary levels of GI and GL in women with breast cancer during chemotherapy treatment and their relationships to body fat and phase angle. Twenty-five patients were assessed according to demographic, clinical, anthropometric, and food consumption data. Dietary intake was assessed by 24-h dietary recalls applied on nonconsecutive days. Anthropometric measures and body composition were determined at all study timepoints: prior to the first chemotherapy cycle (T0), immediately after the last chemotherapy cycle (T1), and 2 months after T1 (T2). There was no difference in mean GI and GL among study timepoints. However, a high prevalence of inadequate GI and GL values was noted, independent of study timepoint. GI and GL were associated with phase angle at T1. GI was associated with percentage fat at T0 only. Dietary GI and GL were unchanged during chemotherapy, but were associated with indicators of clinical outcome, such as percentage fat and phase angle.

RESUMEN

The aim of the present study was to estimate the population coverage of recording food intake markers in Brazil's Food and Nutrition Surveillance System (Sisvan) and mean annual percent change (APC) in coverage according to the system used for data entry (e-SUS APS and Sisvan Web). We conducted an ecological time series study of the period 2015-2019. The data were stratified into region and age group. APC in coverage was calculated using Prais-Winsten regression and the correlation between APC and HDI, GDP per capita and primary healthcare coverage was assessed using Spearman's correlation coefficient. Population coverage of recording food intake markers at national level was 0.92% in 2019. Mean APC in coverage throughout the period was 45.63%. The region and age group with the highest coverage rate were the Northeast (4.08%; APC=45.76%, p<0.01) and children aged 2-4 years (3.03%; APC=34.62%, p<0.01), respectively. There was an upward trend in data entry using e-SUS APS, to the detriment of Sisvan Web. There was a positive correlation between APC in coverage using e-SUS APS and HDI and GDP per capita in some age groups. Population coverage of recording Sisvan food intake markers remains low across the country. The e-SUS APS has the potential to be an important strategy for expanding food and nutrition surveillance.


O objetivo deste estudo foi estimar a cobertura populacional e a taxa de incremento anual (TIA) média, em âmbito nacional, do registro de marcadores do consumo alimentar do Sistema de Vigilância Alimentar e Nutricional (Sisvan), entre 2015 e 2019, considerando a entrada dos dados via Estratégia e-SUS APS e Sisvan Web. Trata-se de estudo ecológico de séries temporais, com estratificação por macrorregiões e faixas etárias. A TIA da cobertura foi calculada utilizando regressão de Prais-Winsten e a correlação com IDH, PIB per capita e cobertura da APS foi avaliada por teste de Spearman. A cobertura populacional do registro de marcadores de consumo alimentar no país foi de 0,92% em 2019, com TIA significante de 45,63% desde 2015. As maiores coberturas foram observadas na região Nordeste (4,08%; TIA=45,76%, p<0,01) e em crianças entre 2 e 4 anos (3,03%; TIA=34,62%, p<0,01). Houve tendência crescente para a entrada dos dados via e-SUS APS, em detrimento do Sisvan Web. A TIA da cobertura dos registros via e-SUS APS exibiu correlação positiva com IDH e PIB per capita em alguns recortes etários. A cobertura populacional do registro de marcadores de consumo alimentar do Sisvan ainda se mostra incipiente no país e o e-SUS APS parece ser uma estratégia relevante para sua expansão.

RESUMEN

INTRODUCTION: Supplementation with probiotics for patients with chronic kidney disease (CKD) may be associated with decreased systemic inflammation. OBJECTIVE: To assess the impact of oral supplementation with probiotics for patients with CKD on hemodialysis. METHOD: This double-blind randomized clinical trial included 70 patients on hemodialysis; 32 were given oral supplementation with probiotics and 38 were in the placebo group. Blood samples were collected at the start of the study and patients were given oral supplementation with probiotics or placebo for three months. The probiotic supplement comprised four strains of encapsulated Gram-positive bacteria: Lactobacillus Plantarum A87, Lactobacillus rhamnosus, Bifidobacterium bifidum A218 and Bifidobacterium longum A101. Patients were given one capsule per day for 3 months. Blood samples were taken throughout the study to check for inflammatory biomarkers. Non-traditional biomarkers Syndecan-1, IFN-y, NGAL, and cystatin C were measured using an ELISA kit, along with biochemical parameters CRP, calcium, phosphorus, potassium, PTH, GPT, hematocrit, hemoglobin, glucose, and urea. RESULTS: Patients given supplementation with probiotics had significant decreases in serum levels of syndecan-1 (239 ± 113 to 184 ± 106 ng/mL, p = 0.005); blood glucose levels also decreased significantly (162 ± 112 to 146 ± 74 mg/dL, p = 0.02). CONCLUSION: Administration of probiotics to patients with advanced CKD was associated with decreases in syndecan-1 and blood glucose levels, indicating potential improvements in metabolism and decreased systemic inflammation.

RESUMEN

OBJECTIVES: The use of prebiotics has an effect on postprandial glucose and insulin concentrations; however, the interaction between the previous profile of the intestinal microbiota and the effect of supplementation with prebiotics is not clear. Our objective was to evaluate the effect of previous intestinal microbiota profile on the postprandial insulin response to yacon syrup, used as a source of fructooligosaccharides (FOSs), in young women. The product presents high levels of FOS. METHODS: In this double-blind, crossover, randomized clinical trial, 40 adult women were allocated to receive a breakfast containing 40 g of yacon syrup (14 g FOS, intervention A) or a breakfast containing 40 g of placebo (intervention B). On each intervention day, after 12 h of fasting, an aliquot of blood was collected for insulin analysis at 0, 15, 30, 45, 60, 90, and 120 min. The fecal sample was collected before the beginning of the interventions, and the DNA was extracted and quantified, with subsequent amplification of the 16S region, next-generation sequencing, and analysis of sequencing data. RESULTS: The glucose and insulin concentrations were reduced after ingestion of yacon syrup compared with placebo, specifically at the 30 min to insulin. After the receiver operating characteristic analysis, six volunteers who did not respond to the yacon consumption intervention were identified. The abundance of the phylum Actinobacteria (P = 0.021) and the order Bifidobacteriales (P = 0.013) were positively associated with better insulin response. Other main phyla were not associated with intervention response. CONCLUSIONS: The previous profile of the intestinal microbiota has an effect on the postprandial insulin response to FOSs, mainly in the phylum Actinobacteria and Bifidobacteriales order.

RESUMEN

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

RESUMEN

OBJECTIVE: to analyze the temporal trend of Food and Nutrition Surveillance System (Sistema de Vigilância Alimentar e Nutricional - SISVAN) coverage and the nutritional status of older adults, and its correlation with indicators of social inequality in Brazil between 2008-2019. METHODS: this was an ecological study using records from SISVAN, related to the population aged 60 years and older; the temporal trend of coverage and the correlation between indicators of social inequality and increment rate of nutritional status were analyzed; slope index of inequality and concentration index were used to measure absolute and relative inequalities. RESULTS: 11,587,933 records were identified; national coverage increased from 0.1% (2008) to 2.9% (2019), with a statistically significant upward trend; a moderate inverse correlation with an annual increment rate of overweight between human development index and gross domestic product per capita, was found. CONCLUSION: there was an increasing trend in SISVAN coverage; the increase in overweight was associated with social inequality.

RESUMEN

Introduction: Objective: this study aimed to evaluate if there is an association of intake of coffee and its polyphenols with mammographic findings in women treated at a breast care service unit of the Unified Health System (SUS), Brazil. Research methods and procedures: this was a cross-sectional study with 532 women treated at a health service. The participants were divided according to their mammographic reports into two groups: without and with altered findings. Two 24-h dietary recalls were applied and coffee consumption was categorized into three groups (less than 1 cup, 1 to 3 cups, and more than 3 cups). Phenolic acids were determined using the Phenol Explorer program. The intake of polyphenols was calculated by adding the values obtained from the total amount of coffee consumed during the day. The Multiple Source Method (MSM) was applied to analyze the usual intake. Results: of the 532 women, 178 (33.5 %) had altered mammographic findings. The participants' average daily coffee intake was 193.4 mL. No significant association was found between coffee consumption and mammographic findings. However, it was found that the second tertile of polyphenols was a protective factor for breast changes. Conclusion: Coffee polyphenols are protective against breast changes in the group evaluated and, thus, can help prevent breast cancer.


Introducción: Objetivo: este estudio tuvo como objetivo evaluar si existe una asociación de la ingesta de café y sus polifenoles con los hallazgos mamográficos de mujeres tratadas en una unidad de patología mamaria del Sistema Unificado de Salud (SUS), Brasil. Métodos y procedimientos de investigación: este fue un estudio transversal con 532 mujeres tratadas en un servicio de salud. Las participantes se dividieron de acuerdo con sus informes mamográficos en dos grupos: sin y con hallazgos alterados. Se aplicaron dos registros dietéticos de 24 horas y el consumo de café se clasificó en tres grupos (menos de 1 taza, 1 a 3 tazas y más de 3 tazas). Los ácidos fenólicos se determinaron utilizando el programa Phenol Explorer. La ingesta de polifenoles se calculó sumando los valores obtenidos de la cantidad total de café consumido durante el día. Se aplicó el método de fuentes múltiples (MSM) para analizar la ingesta habitual. Resultados: de las 532 mujeres, 178 (33,5 %) tenían hallazgos mamográficos alterados. La ingesta diaria promedio de café de los participantes fue de 193,4 ml. No se encontró una asociación significativa entre el consumo de café y los hallazgos mamográficos. Sin embargo, se encontró que el segundo tercil de polifenoles era un factor protector para los cambios mamarios. Conclusión: los polifenoles del café son protectores contra los cambios mamarios en el grupo evaluado y, por lo tanto, podrían ayudar a prevenir el cáncer de mama.

RESUMEN

This study aimed to analyze whether community food environments are associated with individual food consumption among nutrition students and newly graduated nutritionists. This cross-sectional study used data from the Nutritionists' Health Study cohort, which included 357 undergraduate nutrition students from the city of Fortaleza, Ceará, Brazil. Exposure to the food environment was defined as the proximity and availability of food outlets within a 500 m buffer from the participants' homes. Food consumption was assessed using a Food Frequency Questionnaire and analyzed according to the NOVA classification. Multi-level linear regression models with fixed effects were used to estimate the presence of food outlets within the buffer and their association with food consumption. The presence of mini-markets in the buffer in the fourth quartile was associated with lower consumption of ultra-processed foods (UPF) when observing socioeconomic and lifestyle conditions (ß = -3.29; 95% CI = -6.39 to -0.19). The presence of bakeries and coffee shops was related to lower consumption of ultra-processed foods among participants when observing socioeconomic conditions (ß = -3.10; 95% CI = -6.18 to -0.02). There was no clear evidence of an association between the type of food outlet and UPF consumption. The community food environment seemed to influence food consumption among study participants, although clearer and more consistent evidence on this subject is needed.

RESUMEN

OBJECTIVE: To describe the prevalence of underweight and obesity indicators among individuals registered as traditional peoples and communities in the Food and Nutrition Surveillance System, across Brazil, in 2019. METHODS: This was a descriptive study using individual secondary data from participants receiving care in the Primary Health Care within the Brazilian National Health System. RESULTS: In the study population (N = 13,944), there was a higher prevalence of short stature among male children and adolescents (14.2%), when compared to their female counterparts (11.8%); in the adult female population, there was a higher prevalence of obesity (23.0%), when compared to the male population (11.3%); the prevalence of low height-for-age in riverine communities (18.5%) and obesity in the adult faxinalense population (75.1%) stood out. CONCLUSION: Anthropometric disparities between different communities require tailored responses, emphasizing targeted primary health care and programs to ensure food and nutrition security. MAIN RESULTS: It was possible to identify a higher prevalence of low weight and height-for-age in the child population of riverine communities, while faxinalense communities showed a higher prevalence of obesity in adults. IMPLICATIONS FOR SERVICES: Continuous improvement in the implementation of SISVAN protocols is recommended, as well as strengthening the assistance provided to communities with the worst indicators. PERSPECTIVES: Studies assessing the potential impact of interventions to mitigate the effects of malnutrition in communities, through in-depth qualitative research or probabilistic quantitative studies using primary data.

RESUMEN

Studies on childhood feeding and current food consumption, according to the NOVA classification, in adults are scarce. The objective of this study was to evaluate the relationship between childhood dietary practices and the current consumption of different categories of processed foods in young adults using data from the Nutritionists' Health Study (NutriHS) cohort. A cross-sectional analysis was performed using data of 392 on nutrition undergraduate students or nutritionists aged ≥18 years. Current food consumption was assessed using a food frequency questionnaire and the NOVA classification. The investigated childhood eating practices included fruit and vegetable intake, exclusive breastfeeding, and other breastfeeding practices. Participants breastfed with introduction of solid, semi-solid or soft foods before 6 months had higher current consumption of processed foods than those who were not breastfed (ß = 4.30; 95% confidence interval [CI] = 0.56-8.04) and those who did not have the habits of eating fruits and vegetables during childhood consumed less unprocessed and minimally processed foods in adulthood than those who ate fruits and vegetables during infancy (ß = -3.76; 95% CI = -0.82 to -6.70). Further, later introduction of infant formula or other types of milk between 3 and 5 months of age had a lower current consumption of ultra-processed foods than those fed infant formula or other types of milk before 1 month age of life (ß = -3.09; 95% CI = -6.12 to -0.06). In conclusion, childhood feeding practices were linked to food consumption in adult life in NutriHS cohort, highlighting that the first 1000 days of life seems to impact on food choices during adulthood, with potential to protect against nutrition-related diseases later in life.

RESUMEN

Introduction: Introduction: inadequate consumption of micronutrients is an emerging public health problem that can compromise health. Objectives: to assess whether the quality of dietary carbohydrates is associated with the consumption of 13 micronutrients in a sample of women monitored by the Brazilian Unified Health System. Methods: this cross-sectional study included 648 women monitored by the Brazilian Unified Health System. The association between quality of dietary carbohydrates and adequacy of consumption of 13 micronutrients was investigated using logistic regression models adjusted for potential confounding variables. Results: the consumption of micronutrients increased as the quality of carbohydrates improved. The micronutrients with the highest prevalence of inadequate intake were vitamin A, magnesium, manganese, and thiamine. After adjustments using logistic regression models, women in the third tertile of the carbohydrate quality index were less likely to have an inadequate consumption of magnesium (odds ratio (OR), 0.29; 95 % confidence interval (CI), 0.14-0.59), manganese (OR, 0.32; 95% CI, 0.21-0.49), and copper (OR, 0.22; 95% CI, 0.12-0.37). Conclusions: intake of a higher quality of dietary carbohydrates is associated with improved adequacy in consumption of most micronutrients in women monitored by the Brazilian Unified Health System, especially magnesium, manganese, and copper, after adjustment using regression models.


Introducción: Introducción: el consumo inadecuado de micronutrientes es un problema de salud pública emergente que puede comprometer la salud. Objetivo: evaluar si la calidad de los carbohidratos de la dieta está asociada con el consumo de 13 micronutrientes en una muestra de mujeres monitoreadas por el Sistema Único de Salud de Brasil. Métodos: este estudio transversal incluyó a 648 mujeres monitoreadas por el Sistema Único de Salud de Brasil. La asociación entre la calidad de los carbohidratos de la dieta y la adecuación del consumo de 13 micronutrientes se investigó mediante modelos de regresión logística ajustados por posibles variables de confusión. Resultados: el consumo de micronutrientes aumentó a medida que mejoraba la calidad de los carbohidratos. Los micronutrientes con mayor prevalencia de ingesta inadecuada fueron: vitamina A, magnesio, manganeso y tiamina. Después de los ajustes mediante modelos de regresión logística, las mujeres del tercer tercil del índice de calidad de carbohidratos tenían menos probabilidades de tener un consumo inadecuado de magnesio (odds ratio (OR): 0,29; intervalo de confianza (IC) del 95 %: 0,14-0,59), manganeso (OR: 0,32 ; IC del 95 %: 0,21 a 0,49) y cobre (OR: 0,22; IC del 95 %: 0,12 a 0,37). Conclusiones: la ingesta de una mayor calidad de carbohidratos en la dieta se asocia con una mejor adecuación en el consumo de la mayoría de los micronutrientes en mujeres monitoreadas por el Sistema Único de Salud de Brasil, especialmente magnesio, manganeso y cobre, después del ajuste mediante modelos de regresión.

RESUMEN

BACKGROUND: COVID-19 (coronavirus disease 2019) is an infectious disease which led to a pandemic. Social isolation was therefore adopted as the main measure to prevent contamination and maintain public health. Some changes can occur in stress levels, sleep quality, dietary consumption, and mood (such as levels of anxiety and depression). The aim of this study is to describe the association and prediction between social isolation during the COVID-19 pandemic, symptoms of stress, anxiety and depression, and food consumption self-reported. METHODS: This cross-sectional, quantitative, and descriptive study, with a non-probabilistic sample design for convenience, was carried out with 1,004 Brazilians, aged between 18 and 85 years old, from August to December 2020. A virtual questionnaire was applied on socioeconomic and lifestyle data, changing in food consumption, and Depression, Anxiety and Stress Scale (DASS-21) self-reported. The data were analyzed applying the chi-square test for comparison between male and female, and a linear regression was applied to explore associations and predictions of variables that may be strongly associated, using anxiety, depression and stress as dependent and self-reported changes in food consumption. The strength of association of each category of independent variables on the levels of change in food consumption was estimated using ß coefficient and 95%CI, in the SPSS software (version 26.0). RESULTS: Although most declared that consumption remained the same, a small important increase was detected in some groups such as bread, pasta, potatoes, cassava. The consumption of plant-based foods remained unchanged according to the data collected. An increase of 13.25% of sugar sweetened beverages, 23.51% of alcoholic beverages, 37.25% of added of sugar, and 20.42% of fast foods was self-reported, and 52.7% stopped or reduced the practice of physical activity. The self-reported level of stress, anxiety, and depression reached 38.8%, 40.90% and 32.90. Changes in food consumption to predict stress, anxiety or depression symptoms were observed in relation to decrease red meat, fish, chicken, eggs, dairy, vegetables, legumes, and fruits, to increased consumption were associated to dairy, fats, sugar sweetened beverages, and fast foods. CONCLUSIONS: A remarkable increase in Fast foods and alcoholic beverages were observed. Carbohydrate-rich foods was associated to stress, and anxiety symptoms. The same was observed in increase of caloric foods such as fats, sugar sweetened beverages, and fast foods. Besides the decrease of proteins, vitamins, and fibers sources foods had a strength association with stress, anxiety, and depression symptoms.
