RESUMO

OBJECTIVES: "Pocket formulas" are practical alternatives for calculating an individual's total energy expenditure (TEE). Typically, more sophisticated predictive equations are used, such as the new equations proposed in the Dietary Reference Intakes (DRI). Nevertheless, these new equations necessitate estimating physical activity levels (PALs). The aim of this study was to compare the use of pocket formulas (kcal/kg of body weight) with the new predictive equations for energy expenditure proposed by the DRI (2023) in healthy women and with the doubly labeled water (DLW) method to predict TEE. METHODS: The TEEs of healthy adult women were measured by DLW and calculated using the pocket formulas (× 20, × 25, × 30, and × 35 kcal/kg of body weight) and the new DRI equation. PALs by triaxial accelerometers were also collected. RESULTS: The study included 55 women. For the entire sample, the × 30 pocket formula had the lowest bias (-6%; limits of agreement [LOAs]: -39.8; 27.5; root mean square error: 373.4) and the highest precision (42%). The pocket formulas showed reasonable agreement in the different body mass index categories compared with the results found by the 2023 DRI proposal. For individuals with normal weight, the agreement was × 35 kcal/kg: bias (%) = -4.8; LoA = -41.5; 31.8, with overweight, it was × 30 kcal/kg: bias (%) = -2.2; LoA = -25.1; 20.6, and with obesity, it was × 30 kcal/kg: bias (%) = 4.2; LoA = -21.1; 29.4. CONCLUSION: Pocket formulas provide a reasonable agreement with TEE in healthy, sedentary, or low-active adult women, which may be a more simplistic strategy when there is no PAL data for calculating the DRI equations.

RESUMO

The food addiction construct is receiving increasing attention from researchers and clinicians worldwide. Given its rise, scientific production on the subject is increasingly abundant. Conducting studies evaluating food addiction in emerging countries is of great importance, given that most scientific production comes from high-income countries. A recent study aimed to explore the prevalences of orthorexia nervosa and food addiction and their associations with dietary diversity in university students in Bangladesh during the COVID-19 pandemic. This correspondence presents questions about using the older version of the modified Yale Food Addiction Scale to assess food addiction. It also highlights issues related to the prevalence of food addiction observed in the study.

RESUMO

ABSTRACT Objective: This study aimed to assess the agreement between the total energy expenditure (TEE) estimated by the activPAL® triaxial accelerometers (ACC) and the TEE measured by the doubly labeled water method (DLW), as well as to assess if these values differ between the classifications of body mass index (BMI). Materials and methods: This is a cross-sectional study. Low-income adult women (19-45y) with BMI ≥ 18.5 kg/m2 were included. Accelerometry data (activPAL®) were collected over 7 consecutive days, which were used to calculate TEE-ACC and compared with DLW data. The Bland-Altman method, concordance correlation coefficient and root mean square error were used to assess agreement between methods. Results: The sample consisted of 55 women with a mean age of 31 ± 5 years. The agreement between TEE-ACC and TEE-DLW showed a bias of -142.5 kcal (-7.1%). Among the BMI classifications, participants with normal weight show a bias of -417.1 kcal (-21.0%), participants with overweight, -87.5 kcal (-3.9%) and participants with obesity, 97.5 kcal (4.3%). Furthermore, the bias between the methods showed a significant and positive correlation with the body weight (r = 0.49; p < 0.01). Conclusion: The TEE-ACC estimates from activPAL® were reasonably accurate when compared to the TEE-DLW, especially in women with overweight and obesity, being much less accurate in individuals with normal weight.

RESUMO

Resumo Objetivo Verificar se o risco de sarcopenia em pessoas idosas diagnosticadas com covid-19 associa-se com demanda por cuidados intensivos, ventilação mecânica e óbito. Método Estudo multicêntrico do tipo coorte, que incluiu pessoas idosas (≥65 anos) com diagnóstico laboratorial confirmado de covid-19. Foram coletados dados relacionados às características sociodemográficas, clínicas e nutricionais. O risco de sarcopenia foi avaliado pelo questionário Sarcopenia Risk Screening. As variáveis de desfecho foram: necessidade de terapia intensiva, ventilação mecânica e óbito. Foram realizadas regressões logísticas para verificar a associação dos desfechos clínicos e o risco de sarcopenia, com as seguintes variáveis de ajuste: idade, sexo, renda familiar, atividade física, hipertensão, diabetes, doença cardiovascular doença pulmonar obstrutiva crônica e índice de massa corporal. Resultados Foram incluídas no estudo 264 pessoas idosas com covid-19, com média de idade de 71,7 (±8,2) anos. Cento e quarenta e oito pessoas idosas (56,1%) tinham risco de sarcopenia. Hipertensão, diabetes e doença cardiovascular foram as principais comorbidades identificadas nas pessoas idosas, respectivamente, 75,4%, 45,5% e 28,4%. O risco de sarcopenia nas pessoas idosas hospitalizadas com covid-19 aumentou em mais de 2 vezes as chances de internamento na UTI (OR: 2,71 [1,57;4,68], p<0,001), em cerca de 5 vezes as chances de ventilação mecânica (OR: 5,19 [2,75;9,78], p<0,001) e em mais de 3 vezes as chances de óbito (OR: 4,05 [2,05;7,98], p<0,001). Conclusão Em pessoas idosas hospitalizadas com covid-19, a pré-existência do risco de sarcopenia foi preditor de desfechos clínicos desfavoráveis.


Abstract Objective To investigate whether the risk of sarcopenia in older adults diagnosed with covid-19 is associated with the need for intensive care, mechanical ventilation, and mortality. Method A multicenter cohort study was conducted, including older adults (≥65 years) with laboratory-confirmed covid-19 diagnosis. Data related to sociodemographic, clinical, and nutritional characteristics were collected. The risk of sarcopenia was assessed using the Sarcopenia Risk Screening questionnaire. Outcome variables included the need for intensive care, mechanical ventilation, and mortality. Logistic regressions were performed to assess the association between clinical outcomes and the risk of sarcopenia, adjusting for the following variables: age, gender, family income, physical activity, hypertension, diabetes, cardiovascular disease, chronic obstructive pulmonary disease, and body mass index. Results The study included 264 older adults with covid-19, with an average age of 71.7 (±8.2) years. One hundred and forty-eight older adults (56.1%) were at risk of sarcopenia. Hypertension, diabetes, and cardiovascular disease were the most common comorbidities identified in older adults, at 75.4%, 45.5%, and 28.4%, respectively. The presence of sarcopenia risk in hospitalized older adults with covid-19 increased the odds of ICU admission by more than 2-fold (OR: 2.71 [1.57; 4.68], p<0.001), nearly 5-fold for mechanical ventilation (OR: 5.19 [2.75; 9.78], p<0.001), and over 3-fold for mortality (OR: 4.05 [2.05; 7.98], p<0.001). Conclusion In hospitalized older adults with covid-19, pre-existing risk of sarcopenia was a predictor of unfavorable clinical outcomes.

RESUMO

Few studies have investigated which types of food are least reported among underreporters of energy intake (EI). This study assessed the association between the underreporting of EI and the consumption report of food groups according to NOVA classification in women in social vulnerability. EI was measured through three 24-h dietary recalls administered by the research team. Total energy expenditure (TEE) was evaluated using the doubly labelled water method. The percentage of EI arising from each NOVA group food classification (unprocessed/minimally processed foods, culinary ingredients, processed foods and ultra-processed foods [UPF]) was calculated. The agreement between the EI and the TEE was assessed using the ratio EI:TEE. Associations were assessed with Pearson's correlation and multivariable linear regression, adjusted for age, education and body fat. The sample (63 women, age: 30.8 years, Body Mass Index: 27.6 kg/m2 ) reported an EI of 1849 kcal and a TEE of 2223 kcal, with a mean EI:TEE of 0.85. There were no significant correlations between the EI:TEE and the reported food intake according to NOVA classifications. Multivariable linear regression also did not show any significant associations (UPF: 8.47, 95% CI: [-3.65; 20.60] %kcal; Processed: -6.85, [-19.21; 7.71] %kcal; Culinary ingredients: 1.30 [-5.10; 7.71] %kcal; Unprocessed/minimally processed: -2.92 [-10.98; 5.13] %kcal). In conclusion, socially vulnerable women that underreport their EI do not report a lower intake of any specific group of foods according to NOVA classification.

RESUMO

OBJECTIVES: The present study aimed to identify associations between extremes in body weight status (underweight and excess body weight) before a COVID-19 diagnosis and clinical outcomes in patients infected with SARS coronavirus type 2. METHODS: A multicenter cohort study was conducted in eight different states in northeastern Brazil. Demographic, clinical (previous diagnosis of comorbidities), and anthropometric (self-reported weight and height) data about individuals who tested positive for COVID-19 were collected. Outcomes included hospitalization, mechanical ventilation, and death. Multivariable logistic regression models, adjusted based on age, sex and previous comorbidities, were used to assess the effects of extremes in body weight status on clinical outcomes. RESULTS: A total of 1308 individuals were assessed (33.6% were elderly individuals). The univariable analyses showed that only hospitalization was more often observed among underweight (3.2% versus 1.2%) and overweight (68.1% versus 63.3%) individuals. In turn, cardiovascular diseases were more often observed in all clinical outcomes (hospitalization: 19.7% versus 4.8%; mechanical ventilation: 19.9% versus 13.5%; death: 21.8% versus 14.1%). Based on the multivariable analysis, body weight status was not associated with risk of hospitalization (underweight: odds ratio [OR]: 1.10; 95% confidence interval [CI] 95%, 0.50-2.41 and excess body weight: OR: 0.81; 95 CI, 0.57-1.14), mechanical ventilation (underweight: OR: 0.92; 95% CI, 0.52-1.62 and excess weight: OR: 0.90; 95% CI, 0.67-1.19), and death (underweight: OR: 0.61; 95% CI, 0.31-1.20 and excess body weight: OR 0.88; 95% CI, 0.63-1.23). CONCLUSIONS: Being underweight and excess body weight were not independently associated with clinical outcomes in patients with COVID-19 in the herein analyzed cohort. This finding indicates that the association between these variables may be confounded by both age and comorbidities.

RESUMO

CONTEXT: Energy expenditure predictive equations can generate inaccurate estimates for overweight or obese individuals. OBJECTIVE: The objective of this review was to determine which predictive equations for resting energy expenditure (REE) and total energy expenditure (TEE) have the lowest bias and the highest precision in adults with overweight and obesity. DATA SOURCES: Searches were performed in January 2022 in MEDLINE, Web of Science, Scopus, CENTRAL, and the gray literature databases. DATA EXTRACTION: Meta-analyses were performed with equations included in more than 1 study. The DerSimonian and Laird random-effects model and the I2 statistic were used to quantify heterogeneity in the quantitative analyses. The Egger test was performed to assess potential publication biases, and metaregressions were conducted to explore the heterogeneity. Findings were presented separated by participants' body mass index classification (overweight and obesity). DATA ANALYSIS: Sixty-one studies were included. The FAO/WHO/UNU (1985) equation, which uses only body weight in its formula, showed the lowest bias in estimating REE (mean difference [MD] = 8.97 kcal; 95% CI = -26.99; 44.94). In the subgroup analysis for individuals with obesity, the Lazzer (2007) equation showed the lowest bias (MD = 4.70 kcal; 95% CI = -95.45; 104.86). The Harris-Benedict equation (1919) showed the highest precision values for individuals with overweight (60.65%) and for individuals with obesity (62.54%). Equations with body composition data showed the highest biases. The equation proposed by the Institute of Medicine (2005) showed the lowest bias (MD = -2.52 kcal; 95% CI = -125.94; 120.90) in estimating the TEE. Most analyses showed high heterogeneity (I2 > 90%). There was no evidence of publication bias. CONCLUSION: For individuals with overweight, the FAO/WHO/UNU (1985) and the Harris-Benedict equations (1919) showed the lowest bias and the highest precision in predicting the REE, respectively. For individuals with obesity, the Harris-Benedict equation (1919) showed the highest precision and the Lazzer equation (2007) showed the lowest bias. More studies are needed on predictive equations to estimate the TEE. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42021262969.

RESUMO

CONTEXT: Polyphenols have antioxidant, anti-inflammatory, and anti-glycation properties. OBJECTIVE: To assess the effects of dietary polyphenols, from food sources or supplements, on the anthropometric, glycemic, renal, inflammatory, and oxidative stress markers in adults with diabetic nephropathy (DN). DATA SOURCES: Systematic searches for randomized clinical trials were performed in MEDLINE, Embase, CENTRAL, Web of Science, LILACS, SciELO, opengrey.eu, and ClinicalTrials.gov databases until December 2021. DATA EXTRACTION: Studies with adults with DN were included. Random-effects meta-analyses were conducted. Risk of bias of the studies and Grading of Recommendations, Assessment, Development, and Evaluation assessment were carried out. DATA ANALYSIS: The searches resulted in 5614 unique occurrences, and 34 full-text articles were retrieved. Of these, 17 studies were included in the qualitative synthesis. Most of the studies used soy protein or milk (n = 5; 0.5-1 g/kg of body weight/d of soy protein, or introduction of 240 mL/d of soy milk) or turmeric/curcumin (n = 5; dose range, 80 to 1500 mg/d) as the intervention. The following outcomes were analyzed: body mass index, glycated hemoglobin (HbA1c), proteinuria, creatinine clearance, glomerular filtration rate (GFR), urinary albumin to creatinine ratio, and levels of fasting blood glucose, insulin, serum urea and creatinine, C-reactive protein, serum tumor necrosis factor-α, and serum malondialdehyde (MDA). The polyphenol intervention significantly decreased HbA1c (n = 7 studies; -0.27% [95%CI, -0.51%, -0.04%]), proteinuria (n = 5 studies; -109.10 [95%CI, -216.57, -1.63] mg/24 h), and MDA (n = 5 studies; z-score: -0.41; 95%CI, -0.71, -0.10), and significantly increased GFR (n = 7 studies; 3.65 [95%CI, 0.15-7.15] mL/min/1.73 m2). Overall, studies showed a high risk of bias, and outcomes showed a low or very-low quality in the Grading of Recommendations, Assessment, Development, and Evaluation assessment. CONCLUSIONS: There is a clinically modest effect of dietary polyphenols intervention in HbA1c, proteinuria, GFR, MDA, and C-reactive protein levels in patients with DN. It is impossible to establish clinical recommendations, because the evidence was of' low or very-low quality and because of the heterogeneity of types and dose regimens used in the studies.

RESUMO

Introduction: Cardiovascular diseases are a serious public health problem in Brazil and comprise one of the causes of absence from work. However, its occurrence can be avoided if there is an early identification of cardiovascular risk factors. Objective: To investigate the frequency of cardiovascular risk factors in employees of an industry in Alagoas and to investigate differences in their occurrence between the sectors of work. Methods: This is an analytical cross-sectional, carried out in February 2019, with employees from the administrative sector and the operational sector of an industry in Alagoas. Sociodemographic, anthropometric, clinical and lifestyle data were collected. Altered blood pressure, anthropometric indicators of cardiovascular risk, smoking, alcohol consumption, physical inactivity and personal or family history of chronic diseases were considered as cardiovascular risk factors. The statistical analysis was performed with the statistical package R, using the package Rcmdr. In order to ascertain possible differences between risk factors in employees of the administrative sector and the operational sector, the t test for independent samples was performed, when continuous variables, and the Pearson chi-square test was performed, when categorical variables, adopting a level significance of 5%. Results: 56 employees were evaluated, with a mean age of 33 ± 8.5 years. Of these, 80.4% were male, 62.5% were overweight, 58.9% consumed alcohol, 53.6% performed some physical activity and 51.8% had a cardiovascular family history. There was no difference in the occurrence of these factors between the sectors of work. Conclusion: The most frequent cardiovascular risk factors were overweight, alcohol consumption and presence of family history, with no difference being identified between workers in the operational sector and the administrative sector. However, the presence of these factors is worrying, mainly because it is a relatively young sample (AU)


Introdução: As doenças cardiovasculares tornaram-se um grave problema de saúde pública no Brasil e compreendem uma das causas de afastamento do trabalho. Entretanto, sua ocorrência pode ser evitada se houver a identificação precoce de fatores de risco cardiovascular. Objetivo: Investigar a frequência de fatores de risco cardiovascular em funcionários de uma indústria de Alagoas e averiguar diferenças em sua ocorrência entre os setores de trabalho. Métodos: Trata-se de um estudo transversal analítico, realizado em fevereiro de 2019, com funcionários do setor administrativo e do setor operacional de uma indústria alagoana. Foram coletados dados sociodemográficos, antropométricos, clínicos e de estilo de vida. Consideraram-se como fatores de risco cardiovascular: pressão arterial alterada, indicadores antropométricos de risco cardiovascular, tabagismo, etilismo, sedentarismo e antecedentes pessoais ou familiares de doenças crônicas. A análise estatística foi realizada com auxílio do pacote estatístico R, usando o pacote Rcmdr. Para averiguar possíveis diferenças entre os fatores de risco em funcionários do setor administrativo e do setor operacional, realizou-se o teste t para amostras independentes, quando variáveis contínuas, e o teste do qui-quadrado de Pearson, quando categóricas, adotando-se nível de significância de 5%. Resultados: Foram avaliados 56 funcionários, com média de idade de 33 ± 8,5 anos. Destes, 80,4% eram do sexo masculino, 62,5% estavam com excesso de peso, 58,9% consumiam álcool, 53,6% realizavam alguma atividade física e 51,8% apresentavam antecedentes familiares cardiovasculares. Não houve diferença quanto à ocorrência desses fatores entre os setores de trabalho. Conclusão: Os fatores de risco cardiovascular mais frequentes foram excesso de peso, consumo de álcool e presença de antecedentes familiares, não tendo sido identificada diferença entre os trabalhadores do serviço operacional e administrativo. No entanto, a presença desses fatores é preocupante, principalmente por se tratar de amostra relativamente jovem (AU)

RESUMO

Reducing sedentary behaviour (SB) and increasing physical activity (PA) by sitting less and standing/walking more is advised to prevent chronic diseases. However, the mechanisms underlying this recommendation are not well established, especially in individuals with obesity living in low-income regions. The present study evaluated whether there are associations between PA indicators (PAI - standing time, walking time and the number of steps/d) and SB indicators (SBI - sitting/lying down time) with the hormonal profile and resting energy expenditure (REE) of adult women living in a low-income region. This is a cross-sectional study. We collected data on hormones (insulin resistance, leptin and thyroid axis), body composition (tetrapolar bioimpedance), REE (indirect calorimetry), and PAI and SBI (triaxial accelerometers, ActivPAL). Multivariable linear models adjusting for age and fat-free mass were performed. Fifty-eight women (mean age of 31 years and BMI of 33 kg/m2) were included. The mean sitting/lying down time and standing time were 16·08 and 5·52 h/d, respectively. Sitting/lying down time showed a direct association with free thyroxine (FT4) (ß = 0·56 ng/dl; 95 % CI = -1·10, -0·02). Standing time showed a direct association with FT4 (ß = 0·75 ng/dl; 95 % CI = 0·01; 1·48) and inverse association with free triiodothyronine (ß = -2·83 pg/ml 95 % CI = -5·56, -0·10). There were no associations between PAI and SBI with the REE, insulin resistance, leptin and thyroid-stimulating hormone. Thus, decreased SB is associated with thyroid hormones levels but not with REE, insulin resistance or leptin in women with obesity living in low-income regions.

RESUMO

This ecological study aimed to analyze the trend of the nutritional status of pregnant adolescent beneficiaries of the Brazilian Bolsa Família conditional cash transfer program in the 2008-2018 period. We evaluated secondary data of pregnant adolescent beneficiaries of the Bolsa Família Program from January 2008 to December 2018, extracted from the public reports of the WEB Food and Nutrition Surveillance System. We accessed the monitoring reports on the consolidated public-access health conditionalities of the Bolsa Família Program, always considering the second validity. An annual variation of -1.2% (95%CI: [-1.6; -0.8] p<0.01) was observed in the prevalence of underweight in Brazil in the studied sample. The prevalence of overweight and obesity in the country had annual variations of 2.9% (95%CI: [2.0; 3.7] p<0.01) and 7.5% (95%CI: [5.7; 9.3] p<0.01), respectively. We conclude by saying, that, in the evaluated period, the prevalence of underweight among pregnant adolescent beneficiaries of the Bolsa Família Program showed a decreasing trend, while the prevalence of overweight and obesity increased throughout Brazil.


Trata-se de um estudo ecológico que objetivou analisar a tendência do estado nutricional de gestantes adolescentes beneficiárias do programa brasileiro de transferência condicionada de renda, Bolsa Família, no período 2008-2018. Foram avaliados dados secundários de gestantes adolescentes beneficiárias do Programa Bolsa Família no período de janeiro de 2008 a dezembro de 2018, extraídos dos relatórios públicos do Sistema de Vigilância Alimentar e Nutricional WEB. Foram consultados os relatórios de acompanhamento das condicionalidades de saúde consolidados de acesso público do Programa Bolsa Família, sempre considerando a 2ª vigência. Observou-se uma variação anual de -1,2% (IC95%: [-1,6; -0,8] p<0,01) na prevalência de baixo peso na amostra estudada. Com relação as prevalências de sobrepeso e obesidade no país, observou-se variações anuais de 2,9% (IC95%: [2,0; 3,7] p<0,01) e 7,5% (IC95%: [5,7; 9,3] p<0,01), respectivamente.

RESUMO

BACKGROUND & AIMS: The phase angle (PA) has been used as an indicator of prognosis and nutritional status because it reflects the integrity of the individuals' cellular function. In contrast to the investigations that assessed acute malnutrition (weight deficit) and PA in children, studies that evaluated the relationship of this indicator with stunting (height deficit) are still scarce and inconclusive. Thus, we aim to investigate whether there are differences in PA according to the classifications of the height-for-age (H/A) index of children under five years of age. METHODS: This is a cross-sectional study carried out in a nutritional recovery center, in households, and in a daycare center in Maceió-Alagoas, Brazil. Anthropometric data were collected, and resistance and reactance were obtained through the use of tetrapolar electrical bioimpedance, from children aged 2-5 years. The PA and the percentage of body fat were calculated. Children were divided into 3 groups: adequate H/A, at-risk of stunting and stunted. Analysis of covariance for the main outcome was performed using age, sex, and the body mass index-to-age as covariates, and the H/A classification as the exposure. RESULTS: The mean children's PA in the adequate H/A group was 3.9° [95% CI 3.6-4.2], while in the group at-risk of stunting and stunted it was 4.5° [95% CI 4.3-4.7] and 4.6° [95% CI 4.4-4.8], respectively, showing statistical difference (p < 0.01). CONCLUSION: In the present sample, stunted children have higher PA values than children with adequate H/A.

RESUMO

Resumo Trata-se de um estudo ecológico que objetivou analisar a tendência do estado nutricional de gestantes adolescentes beneficiárias do programa brasileiro de transferência condicionada de renda, Bolsa Família, no período 2008-2018. Foram avaliados dados secundários de gestantes adolescentes beneficiárias do Programa Bolsa Família no período de janeiro de 2008 a dezembro de 2018, extraídos dos relatórios públicos do Sistema de Vigilância Alimentar e Nutricional WEB. Foram consultados os relatórios de acompanhamento das condicionalidades de saúde consolidados de acesso público do Programa Bolsa Família, sempre considerando a 2ª vigência. Observou-se uma variação anual de -1,2% (IC95%: [-1,6; -0,8] p<0,01) na prevalência de baixo peso na amostra estudada. Com relação as prevalências de sobrepeso e obesidade no país, observou-se variações anuais de 2,9% (IC95%: [2,0; 3,7] p<0,01) e 7,5% (IC95%: [5,7; 9,3] p<0,01), respectivamente. Conclui-se que, no período avaliado, a prevalência de baixo peso entre as gestantes adolescentes beneficiárias do Programa Bolsa Família apresentou uma tendência decrescente, ao passo que as prevalências de sobrepeso e obesidade apresentam uma tendência crescente em todo o Brasil.


Abstract This ecological study aimed to analyze the trend of the nutritional status of pregnant adolescent beneficiaries of the Brazilian Bolsa Família conditional cash transfer program in the 2008-2018 period. We evaluated secondary data of pregnant adolescent beneficiaries of the Bolsa Família Program from January 2008 to December 2018, extracted from the public reports of the WEB Food and Nutrition Surveillance System. We accessed the monitoring reports on the consolidated public-access health conditionalities of the Bolsa Família Program, always considering the second validity. An annual variation of -1.2% (95%CI: [-1.6; -0.8] p<0.01) was observed in the prevalence of underweight in Brazil in the studied sample. The prevalence of overweight and obesity in the country had annual variations of 2.9% (95%CI: [2.0; 3.7] p<0.01) and 7.5% (95%CI: [5.7; 9.3] p<0.01), respectively. We conclude by saying, that, in the evaluated period, the prevalence of underweight among pregnant adolescent beneficiaries of the Bolsa Família Program showed a decreasing trend, while the prevalence of overweight and obesity increased throughout Brazil.

RESUMO

BACKGROUND & AIMS: Time-restricted feeding (TRF) studies have been summarized in previous systematic reviews, but these were not specific for individuals with excess weight and studies involving early time-restricted feeding (eTRF). This meta-analysis aimed to evaluate the effect of eTRF on the metabolic profile of adults with excess weight. METHODS: Data were extracted from MEDLINE, CENTRAL, LILACS, Web of Science, ClinicalTrials.gov, OpenGrey.eu, Greylit, and by manual search. Randomized controlled trials in which the participants were older than 18 years, with a body mass index greater than 25 kg/m2 and that were allocated in an intervention with eTRF were included. The studies should have assessed any of the following outcomes from the metabolic profile: resting metabolic rate, triacylglycerol, total cholesterol, HDL-cholesterol, and LDL-cholesterol, fasting blood glucose, insulin, HOMA-IR, C-reactive protein, Interleukin-6, cortisol, leptin, Ghrelin, Peptide YY and glucagon-like peptide, hemodynamic parameters, and appetite. The risk of bias was assessed using the Cochrane collaboration tool. Publication bias was examined with a funnel plot and Egger's test. GRADE was used to assess the overall quality of evidence. RESULTS: Ten articles from nine randomized clinical trials, with 264 individuals, were included in qualitative analysis and eight articles with 184 individuals were included in the meta-analysis. There were significant effects on the fasting blood glucose (WMD: -2.75; 95% CI [-4.59; -0.90] mg/dL; p < 0.01; I2 = 88.7%; 7 studies) and HOMA-IR. (WMD: -0.50; 95% CI [-0.82; -0.19]; p < 0.01; I2 = 50.8%; 4 studies). The other outcomes were not significant. Three studies showed a high risk of bias. Seven outcomes were classified as very low quality and one as low quality. There was evidence of publication bias for fasting blood glucose. CONCLUSIONS: Although the eTRF regimen seems to have a beneficial effect on the fasting blood glucose and HOMA-IR of individuals with excess weight, the results of this meta-analysis should be analyzed with caution due to the low-quality evidence.

RESUMO

Objetivo:O objetivo deste estudo foi avaliar o uso de um tempero à base de ervas em preparações proteicas como estratégia para a redução da ingestão de sódio por comensais atendidos em uma Unidade de Alimentação e Nutrição (UAN). Material e Métodos:Trata-se de um estudo transversal realizado em uma UAN de uma fábrica. O tempero à base de ervas foi desenvolvido com o auxílio das cozinheiras da unidade. A composição nutricional das preparações proteicas foi determinada com o auxílio de tabelas de composição de alimentos. Para avaliar a aceitação das preparações, foram realizadas análises sensoriais de duas preparações culinárias: peito de frango e acém bovino adicionados do tempero à base de ervas. Foram considerados os seguintes atributos: cor, textura, aroma, aparência e avaliação global, em uma escala hedônica de 9 pontos que varia de "desgostei muitíssimo" a "gostei muitíssimo". O índice de aceitabilidade também foi calculado para todos os atributos. Resultados: Quarenta e um juízes consumidores foram recrutados para realizar a análise sensorial. Houve uma redução importante nos níveis de sódio de 60,2% (de 939,2 mg para 375,3 mg) e 23,3% (de 709,7 mg para 544,0 mg) por 100g de peito de frango e acém bovino, respectivamente, e um aumento no teor de fibra das preparações que receberam o tempero à base de ervas. O índice de aceitação global de peito de frango temperado e filé de carne bovina foi de 87,8% e 83,8%, respectivamente. Conclusão: A substituição de temperos ultraprocessados por temperos à base de ervas em preparações de proteínas foi bem aceita entre comensais da UAN.


Objective:This study aimed to evaluate the use of a herbs-based seasoning in protein preparations as a strategy for reducing sodium intake by diners served at a Food and Nutrition Unit (FNU). Material and Methods: This was a cross-sectional study carried out in a FNU factory. The herbs-based seasoning was developed with the help of the unit's cooks. The proximate composition of protein preparations was determined with the aid of food composition tables. To assess the acceptance of the preparations, a sensory analysis was performed for two culinary preparations: chicken breast and beef chuck steak added with the herbs-based seasoning. The following attributes were considered for evaluating colour, texture, aroma, appearance and overall evaluation, on a 9-point hedonic scale ranging from "I disliked a lot" to "I liked a lot". The acceptability index was also calculated for all attributes. Results: Forty-one consumer judges were recruited to perform the sensory analysis. There was an important reduction in sodium levels of 60.2% (from 939.2 mg to 375.3 mg) and 23.3% (from 709.7 mg to 544.0 mg) per 100g of chicken breast and beef chuck steak, respectively, and an increase in the fiber content of the preparations that received the herbs-based seasoning. The global acceptance index of seasoned chicken breast and beef chuck steak was 87.8% and 83.8%, respectively. Conclusion: The substitution of ultra-processed seasoning for herbs-based seasoning in protein preparations was well accepted among FNU diners.
