Active and sedentary behaviours in children aged 7 to 10 years old: the urban and rural contexts, Brazil.

BACKGROUND: Although the effects of physical activity (PA) on health and wellness are well-established, incorporating sedentary behaviours in the daily lives of populations from high- and medium-income countries is becoming increasingly common. Regardless of other factors, the area of residence can influence the physical activity level and sedentary behaviours. The aim of this study was to identify and analyse active and sedentary behaviours and factors associated with physical activity in two different geographical areas in south-eastern Brazil. METHODS: 1.770 schoolchildren aged 7-10 years old were studied. Parents or caregivers completed a validated questionnaire on PA and sedentary behaviours. Screen time (ST) was calculated from the time spent watching television, playing video games and using the computer. The level of active PA (>300 minutes per week) was identified and compared between the areas of study. Parametric and non-parametric tests and Poisson regression model with robust variance were used for statistical analysis. RESULTS: Compared to schoolchildren from the urban area, those from the rural area showed a higher percentage of compliance with the PA recommendations (87 vs. 69.7%) and screen time <2 h (34.8 vs. 18.8%) and less participation in supervised PA. Active commuting to school was more common among schoolchildren from urban areas, although using a bicycle was more common in rural areas. The characteristics of children who do not meet the recommended weekly PA are as follows: being female, living in urban areas, being overweight, not using video games or performing supervised PA. Total ST as well as daily use of television and the computer was not associated with physical activity level in the present sample. Participation in supervised physical activities in both areas was found to increase the prevalence of being active in the areas studied. CONCLUSIONS: The results of the present study suggest that while schoolchildren from rural areas are more active and spend less time on sedentary activities than those from the urban area, the time spent in sedentary behaviors, such as watching television, playing video games and using the computer, is high in both contexts, and it is not associated with physical activity recommendation compliance.

[Development and validation of the food quality score in ELSA-Brasil]. / Desarrollo y validación de la puntuación de calidad alimentaria en el ELSA-Brasil.

Introduction: miology.Introduction: nutritional epidemiology seeks to understand the relationship between food consumption and the occurrence of diseases. During the COVID-19 pandemic, the Longitudinal Study of Adult Health (ELSA-Brasil) used a reduced Food Frequency Questionnaire (FFQ) to compare diet quality between cohort stages. Objective: to develop and validate an index created using a food quality score (FQS) using the FFQ of ELSA-Brasil. Methods: a cross-sectional study carried out between August 2020 and March 2021 with 4262 participants. For each frequency of consumption of healthy and unhealthy food markers, a score was given. Validity and reliability were tested using Pearson's correlation, principal component analysis (PCA) and Cronbach's alpha. Tests were performed to verify differences between individual characteristics and FQS. Results: the PCA indicated a total variability of 42.5 %. Women and individuals with higher age, physical activity and per capita income had a higher FQS, while those who reported higher consumption of alcohol and being smokers had a lower score. Cronbach's alpha was 0.47. Conclusion: the FQS showed a satisfactory validity and reliability and was associated with socioeconomic and lifestyle data. Therefore, it is a useful tool for comparing dietary information, thus contributing to nutritional epidemiology.

Introducción: Introducción: la epidemiología nutricional busca comprender la relación entre el consumo de alimentos y la ocurrencia de enfermedades. Durante la pandemia de COVID-19, el Estudio Longitudinal de Salud del Adulto (ELSA-Brasil) utilizó un Cuestionario de Frecuencia de Alimentos (CFA) reducido para comparar la calidad de la dieta en diferentes etapas de la cohorte. Objetivo: desarrollar y validar un índice creado a partir de un score (o puntuación) de calidad alimentaria (SCA) utilizando el CFA del ELSA-Brasil. Métodos: estudio transversal realizado entre agosto de 2020 y marzo de 2021 con 4262 participantes. Para cada categoría de frecuencia de consumo de alimentos indicadores de alimentación saludable y no saludable, se otorgó una puntuación. La validez y la fiabilidad se estimaron mediante el coeficiente de correlación de Pearson, el análisis de componentes principales (ACP) y la alfa de Cronbach. Se realizaron pruebas para verificar las diferencias entre las características individuales y la SCA. Resultados: el ACP indicó una variabilidad total del 42,5 %. Las mujeres y los individuos con mayor edad, actividad física e ingreso per cápita obtuvieron un valor de SCA más alto, mientras que aquellos que reportaron un mayor consumo de alcohol y tabaquismo obtuvieron una puntuación más baja. La alfa de Cronbach fue de 0,47. Conclusión: la SCA mostró una validez y confiabilidad satisfactorias y se asoció con datos socioeconómicos y de estilo de vida. Por lo tanto, es una herramienta útil para comparar la información dietética, contribuyendo a los futuros análisis en epidemiología nutricional.

Association between Dietary Inflammatory Index and Gastric Adenocarcinoma: A Multicenter Case-Control Study in Brazil.

BACKGROUND: Few studies have evaluated the association between diet-related inflammation and gastric adenocarcinoma (GA) and evidence is scarce in Brazil. This study evaluated the association between a pro-inflammatory diet and GA. METHODS: A multicenter case-control study was conducted in Brazil. A total of 1645 participants-492 cases, 377 endoscopy controls, and 776 hospital controls-were included. Energy-adjusted Dietary Inflammatory Index (E-DIITM) scores were derived from a validated food frequency questionnaire. We used binary and multinomial logistic regression models for the analysis of total GA, and its subtypes (cardia and non-cardia, intestinal, and diffuse histological subtypes). RESULTS: In cases versus endoscopy controls, a pro-inflammatory diet, estimated by higher E-DII scores, was associated with a higher risk GA (ORQ4vsQ1: 2.60, 1.16-5.70), of non-cardia GA (OR: 2.90, 1.06-7.82), and diffuse subtype (OR: 3.93, 1.59-9.70). In cases versus hospital controls, higher E-DII scores were associated with a higher risk of GA (OR: 2.70, 1.60-4.54), of cardia GA (OR: 3.31, 1.32-8.24), non-cardia GA (OR: 2.97, 1.64-5.39), and both intestinal (OR: 2.82, 1.38-5.74) and diffuse GA (OR: 2.50, 1.54-5.11) subtypes. CONCLUSIONS: This study provides evidence that a pro-inflammatory diet is associated with an increased risk of GA in Brazil. E-DII requires the inclusion of sodium due to its importance in carcinogenesis.

Nutrient Patterns and Risk of Osteopenia in Postmenopausal Women.

Nutrient patterns (NPs) and the synergistic effect between nutrients have been shown to be associated with changes in bone mineral density (BMD). This study aimed to identify NPs and to associate them with BMD categories in postmenopausal women. This cross-sectional, observational, analytical study was carried out with women in menopause for at least 12 months, aged ≥50 years. Sociodemographic, lifestyle, and clinical variables were investigated. BMD was assessed using dual energy X-ray absorptiometry. A dietary assessment was conducted using a food frequency questionnaire, and three nutrient patterns (NP1, NP2, and NP3) were extracted from the principal component analysis. Multivariate logistic regression was applied to investigate the association between BMD classifications and NP consumption. A total of 124 women, aged on average, 66.8 ± 6.1 years, were evaluated. Of these, 41.9% had osteopenia and 36.3% had osteoporosis. The NP1 (OR: 6.64, [CI95%: 1.56-28.16]; p = 0.010), characterized by vitamin B12, pantothenic acid, phosphorus, riboflavin, protein (total and animal), vitamin B6, potassium, vitamin D, vitamin E, calcium, cholesterol, ß-carotene, omega 3, magnesium, zinc, niacin, and selenium; and the NP2 (OR: 5.03, [CI95%: 1.25-20.32]; p = 0.023), characterized by iron, vegetable protein, thiamine, folate, fibers (soluble and insoluble), PUFA, vitamin A, vitamin K, alpha-tocopherol, copper, sodium, and retinol, was inversely associated with osteopenia. The lower consumption of NP1 and NP2 by postmenopausal women was associated with a higher risk of osteopenia, but not osteoporosis.

Lipid profile and risk of cardiovascular disease in adult transgender men receiving cross-sex hormone therapy: a systematic review.

CONTEXT: A recent US national survey of the health status of the male transgender population has raised awareness about the little-studied relationship between testosterone hormone therapy in transgender men and cardiovascular outcomes. OBJECTIVE: The aim of this systematic review was to assess the relationship between cross-sex hormone therapy in transgender men and lipid profiles and cardiovascular risk. DATA SOURCES: The PubMed, SciELO, SpringerLink, and EBSCOhost databases were searched up to March 2021 for studies assessing the association between cross-sex hormone therapy and the incidence of outcomes related to cardiovascular disease in transgender men over 18 years of age . DATA EXTRACTION: Data extracted were sorted into clinical data (systolic, diastolic, and mean blood pressure), anthropometric data (body mass index, weight, waist circumference, fat mass, and lean mass), and biochemical data (triglycerides, total cholesterol, low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], very low-density lipoprotein cholesterol [VLDL-C], and the HDL-C to LDL-C ratio). DATA ANALYSIS: Study quality was appraised independently by two reviewers using the Cochrane tools for assessment of methodological quality or risk of bias in nonrandomized studies, and the Newcastle-Ottawa Scale was applied. Of 735 studies identified, 11 were included in the review. Most studies reported no change in cholesterol or triglyceride levels after hormone treatment. A reduction in HDL-C levels was observed in 7 of 11 studies, although this alone cannot be considered a cardiovascular risk factor. Likewise, clinical and anthropometric findings showed no changes predictive of cardiovascular risk. CONCLUSIONS: Although these findings suggest that hormone therapy may lead to a decrease in HDL-C levels and an increase in LDL-C levels, they are insufficient to establish a relationship with cardiovascular disease. Furthermore, no significant effects on metabolic and anthropometric values were found. Further studies with higher quality and longer follow-up periods are needed to establish cardiovascular risk. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration number CRD 42020212560.

Multimorbidity and health care of community health workers in Vitória, Espírito Santo, Brazil, 2019: a cross-sectional study. / Multimorbidade e cuidado com a saúde de agentes comunitários de saúde em Vitória, Espírito Santo, 2019: um estudo transversal.

OBJECTIVE: To assess health conditions, health care and lifestyle habits of community health workers (CHW) in Vitória, Espírito Santo, Brazil. METHODS: This was a cross-sectional study using baseline data from an intervention study. Biochemical, anthropometric and hemodynamic examinations and interviews were carried out between October 2018 and March 2019 in Vitória. Appropriate statistical tests, in accordance with the sample design, were performed using SPSS software version 21.0, adopting p<0.05. RESULTS: We assessed 262 CHWs with a mean age of 46.1±9.3 years. High prevalence of prediabetes (22.9%), diabetes mellitus (17.2%), hypertension (37.0%), obesity (39.8%), hypercholesterolemia (57.3%), hypertriglyceridemia (27.1%), multimorbidity (40.8%), physical inactivity (60.9%) and use of anxiolytics/antidepressants (22.5%) was found. Some 40% of the CHWs had three or more morbidities. CONCLUSION: High percentages of chronic diseases, multimorbidity, sedentary lifestyle and use of anxiolytics/antidepressants were found in CHWs in Vitória.

Dietary consumption of selenium inversely associated with osteoporosis in postmenopausal women.

Background: Osteoporosis is a skeletal disease characterized by reduced bone mineral density (BMD), which increases the risk of falls and fractures and reduces mobility. Some nutrients have a well-established role in maintaining bone health and preventing osteoporosis, while selenium (Se) has aroused interest in bone health possibly because of its anti-inflammatory and antioxidant capacity. The aim of this study was to evaluate the association between dietary Se consumption and BMD in postmenopausal women. Materials and methods: Cross-sectional, observational, analytical study carried out with women in menopause for at least 12 months, aged ≥ 50 years. Sociodemographic, lifestyle, and clinical data variables were studied. BMD was assessed using Dual Energy X-ray Absorptiometry (DXA) and the participants classified as having normal BMD, osteopenia, or osteoporosis. Dietary consumption of Se was assessed by the food frequency questionnaire (FFQ) and classified into quartiles of consumption. Multivariate logistic regression with three fit models was applied to investigate the association of BMD with Se consumption quartiles. The significance level adopted for all tests was 5.0%. Results: The final sample consisted of 124 women aged in average 66.8 ± 6.1 years and with a time since menopause of 19.6 ± 8.8 years. According to the BMD, 41.9% of the women had osteopenia and 36.3% osteoporosis. The mean consumption of Se was 154.4 ± 88.7 µg/day. The highest consumption of Se was observed among women with normal BMD (51.9%), whereas lower consumption levels were found in 57.7% of women with osteopenia and in 60.0% of women with osteoporosis (p = 0.003). In the multivariate analysis, after adjusting for possible confounding variables, Se remained associated with the group of women with osteoporosis. Postmenopausal women in the highest quartile (≥94.0 µg/day) of Se consumption had an OR of 0.02 (95%CI: 0.001-0.41; p = 0.012) of having osteoporosis when compared with women in the lowest quartile. Conclusion: Se consumption was associated with BMD and postmenopausal women with higher Se consumption were less likely to have osteoporosis.

Consumption of alcoholic beverages and abdominal obesity: cross-sectional analysis of ELSA-Brasil. / Consumo de bebidas alcoólicas e obesidade abdominal: resultados da linha de base do ELSA-Brasil.

The objective was to analyze the association between alcohol consumption and abdominal adiposity in adults. Cross-sectional study conducted at baseline data from ELSA-Brasil (2008- 2010). The sample consisted of 15,065 civil servants from six education and research institutions (35 to 74 years old, both sexes). To identify central adiposity by measuring waist circumference (WC) and waist-to-hip ratio (WHR), the cutoff points recommended by the World Health Organization were used. Poisson regression models adjusted for potentially confounding variables were tested. About 40% of the sample had elevated WC and WHR. The probability of having elevated WC was 5% and 3% higher in the most exposed group of beer consumption in men and women when compared to the reference group [PR= 1.05 (95% CI 1.02-1.08) and P R= 1.03 (95% CI 1.00-1.07)]. A higher probability of having a high WHR was also found among the highest beer consumers [PR = 1.03 (95% CI 1.00-1.07) in men and PR = 1.10 (95% CI 1.04-1.15) in women]. A greater number of doses/week of alcoholic drink increased the probability of occurrence of high WC and WHR, with the beer contribution being more important.

Objetivou-se analisar a associação entre consumo de bebidas alcoólicas e adiposidade abdominal em adultos. Estudo transversal realizado com dados da linha de base do ELSA-Brasil (2008-2010). A amostra foi constituída por 15.065 servidores públicos de seis instituições de ensino e pesquisa (35 a 74 anos, ambos os sexos). Para identificar adiposidade central por meio das medidas de circunferência da cintura (CC) e relação cintura/quadril (RCQ), utilizou-se os pontos de corte preconizados pela Organização Mundial da Saúde. Para as análises estatísticas foi utilizado o teste qui-quadrado e modelos de regressão de Poisson ajustados por variáveis potencialmente confundidoras. Cerca de 40% da amostra apresentava CC e RCQ elevadas. A probabilidade de apresentar CC elevada foi 5% e 3% maior no grupo mais exposto de consumo de cerveja em homens e mulheres quando comparado ao grupo de referência [RP = 1,05 (IC 95% 1,02-1,08) e RP = 1,03 (IC 95% 1,00-1,07)]. Também foi encontrada maior probabilidade de apresentar RCQ elevada entre os maiores consumidores de cerveja [RP = 1,03 (IC 95% 1,00-1,07) em homens e RP=1,10 (IC 95% 1,04-1,15) em mulheres]. Maior número de doses/semana de bebida alcoólica aumentou a probabilidade de ocorrência de CC e RCQ elevadas, sendo mais importante a contribuição da cerveja.

Agreement between maximum and mean handgrip strength measurements in cancer patients.

BACKGROUND AND AIM: Handgrip strength (HGS) can be used to identify probable sarcopenia, by measuring maximum strength and/or through the average of three measurements. This study analyzed the agreement between maximum and mean HGS measurements in identifying probable sarcopenia in cancer patients. METHODS: Adult individuals of both sexes diagnosed with malignant neoplasm were evaluated. HGS (kg/f) was measured in both hands and nutritional status defined by the Patient-Generated Subjective Global Assessment (PG-SGA). Bland-Altman, Intraclass Correlation Coefficient (ICC), and Cronbach's Alpha tests were applied to assess the agreement between measurements. RESULTS: One hundred forty-one patients aged 60.0 ± 14.2 years were evaluated. There was a predominance of elderly (57.4%), male (53.2%), and non-white (58.2%) individuals, with tumors located in the lower gastrointestinal tract (GIT) (36.9%) and with suspected or some degree of malnutrition (61.0%). For men, the Bland-Altman test showed a mean error of 1.37 (95% CI-1.03 to 3.80) for dominant HGS (DHGS) and 1.50 (95% CI-1.60 to 4.60) for non-dominant HGS (NDHGS), while for women the values were 1.34 (95% CI-0.27 to 2.95) and 1.14 (95% CI-1.10 to 3.39), respectively. The ICC showed excellent reproducibility (> 0.90) and the Cronbach's Alpha was satisfactory (0.99). CONCLUSION: Despite the satisfactory agreement observed between maximum and mean HGS values, in this study, individuals of both sexes with probable sarcopenia were better identified through mean values.

Consumption of alcoholic and non-alcoholic beverages: ELSA-Brasil results. / Consumo de bebidas alcoólicas e não alcoólicas: Resultados do ELSA-Brasil.

The study aims to describe the consumption of alcoholic and non-alcoholic beverages according to sociodemographic, health and location variables. Cross-sectional study with ELSA-Brasil data (2008-2010). A questionnaire was used to collect sociodemographic, food, health data and anthropometry. Descriptive analysis and association with variables of interest were carried out. In the sample, 8% of the total caloric value comes from non-alcoholic beverages (5.6%: sugary drinks), and 4% from alcoholic beverages (2.7%: beer). Consumers of unsweetened and artificially sweetened beverages reported moderate/strong physical activity, former smokers and higher education. The opposite was true for sugary drinks. Eutrophic people reported higher consumption of sugary drinks and those obese, artificially sweetened and beer. Alcohol consumption varied with age (young: beer; elderly: wine/spirits) and education (low education: beer/spirits; higher education: wine). Coffee, natural juice and soda were the most consumed non-alcoholic beverages and beer was the most prevalent alcoholic beverage. Consumption variation was observed according to geographic location. The consumption of sugary and alcoholic beverages is high in Brazil and public health strategies are required.

Objetiva-se descrever o consumo de bebidas alcoólicas e não alcoólicas segundo variáveis sociodemográficas, de saúde e localização. Estudo transversal com dados do ELSA-Brasil (2008-2010). Aplicou-se questionário para coleta de dados sociodemográficos, de alimentação, saúde, além de antropometria. Realizou-se análise descritiva e associação com variáveis de interesse. Na amostra, 8% do valor calórico total é proveniente de bebidas não alcoólicas (5,6%: bebidas açucaradas), e 4% de bebidas alcoólicas (2,7%: cerveja). Os consumidores de bebidas não adoçadas e adoçadas artificialmente realizam atividade física moderada/forte, são ex-fumantes e apresentam escolaridade alta. O oposto foi verificado para as bebidas açucaradas. Indivíduos eutróficos relataram maior consumo de bebidas açucaradas e os obesos, as adoçadas artificialmente e cerveja. O consumo de bebidas alcoólicas variou com a idade (jovens: cerveja; idosos: vinho/destiladas) e escolaridade (baixa: cerveja/destiladas; alta: vinho). Café, suco natural e refrigerante foram as bebidas não alcoólicas mais consumidas e a cerveja a alcoólica mais prevalente. Observou-se variação de consumo segundo a localização geográfica. O consumo de bebidas açucaradas e alcoólicas é alto no Brasil e estratégias de saúde pública são necessárias.

Malnutrition and nutrition impact symptoms (NIS) in surgical patients with cancer.

BACKGROUND AND AIM: Nutrition impact symptoms (NIS) are common in cancer patients and the negative impacts on nutritional status indicate the need for research, diagnosis and nutritional intervention in order to reduce the risk of malnutrition. We aimed to verify the presence of malnutrition, the need for nutritional intervention, NIS and their influence on the nutritional status of surgical patients with cancer. METHODS: This cross-sectional study was carried out in a public tertiary hospital, from March 2017 to October 2019. Nutritional status, the need for nutritional intervention and NIS were assessed through the Patient-Generated Subjective Global Assessment (PG-SGA) in the first 48 hours of hospital admission. RESULTS: Among the 135 patients evaluated, 55.6% were elderly and 51.1% were male; patients had a median age of 62 years and a predominance of cancer located in the lower gastrointestinal tract (35.6%). Malnutrition and the need for nutritional intervention were identified in 60.0% and 90.4% of cases, respectively. The presence of three or more NIS was reported by 51.9% of patients. Significant differences in NIS were observed according to sex, PG-SGA classification and PG-SGA score. After logistic regression analysis, it was determined that the symptoms that increased the chances of malnutrition were anorexia, constipation, strange taste, mouth sores and others (depression, dental or financial problems). CONCLUSION: Malnutrition, the need for nutritional intervention and the presence of three or more NIS were elevated in the patients evaluated. Malnutrition was associated with the presence of NIS, indicating the need for attention and care in antineoplastic treatment.

SARC-CalF-assessed risk of sarcopenia and associated factors in cancer patients.

INTRODUCTION: Introduction: sarcopenia is considered a risk factor for cancer patients, as it increases mortality and post-surgical complications, and reduces response to treatment and quality of life. Objective: to identify the risk of sarcopenia by SARC-CalF, as well as the factors associated with this outcome in patients with cancer of the gastrointestinal tract (GIT) and adnexal glands. Methods: this cross-sectional study included patients with cancer of the GIT and adnexal glands, without edema or ascites, of both sexes and aged ≥ 20 years. Conventional anthropometric variables and handgrip strength (HGS) were measured. The risk of sarcopenia was assessed through the SARC-CalF questionnaire, and nutritional status by the Patient-Generated Subjective Global Assessment (PG-SGA). The data analysis was performed using the SPSS® software, 22.0, with a significance of 5 %. Results: seventy patients took part in the study. Of these, 55.7 % were female, 52.9 % were aged over 60 years, and 64.3 % were non-white. PG-SGA identified 50.0 % of patients as well-nourished and 50.0 % as having some degree of malnutrition. The prevalence of risk of sarcopenia was 28.6 %. There were different correlations between the SARC-CalF score and anthropometric variables (p < 0.05) according to life stage (adults and elderly). After a linear regression analysis the measures that most influenced the SARC-CalF score were arm circumference (AC) and adductor pollicis muscle thickness in the dominant hand (DAPMT) for adults, while for the elderly current weight and DAPTM (p < 0.05) were more relevant. Conclusion: SARC-CalF identified 28.6 % of patients at risk for sarcopenia and was associated with body weight and anthropometric variables indicative of muscle reserve in adults and the elderly.

INTRODUCCIÓN: Introducción: se considera la sarcopenia un factor de riesgo, especialmente para los pacientes con cáncer, ya que aumenta la mortalidad y las complicaciones posquirúrgicas, reduciendo la respuesta al tratamiento y la calidad de vida. Objetivo: identificar el riesgo de sarcopenia por el SARC-CalF y los factores asociados en pacientes con cáncer del tracto gastrointestinal (TGI) y las glándulas anexas. Métodos: estudio transversal descriptivo. Se incluyeron pacientes con cáncer del TGI y glándulas anexas, sin edema o ascitis, de ambos sexos y de edad ≥ 20 años. Se midieron las variables antropométricas convencionales y la fuerza de presión manual (FPM). El riesgo de sarcopenia se obtuvo mediante el cuestionario SARC-CalF y el estado nutricional mediante la valoración global subjetiva generada por el propio paciente (VGS-GP). El análisis de los datos se realizó con el software SPSS®, versión 22.0, con una significancia del 5 %. Resultados: Participaron 70 pacientes. De estos, el 55,7 % eran mujeres, el 52,9 % eran mayores de 60 años y el 64,3 % eran de etnia no caucásica (64,3 %). La VGS-GP identificó un 50,0 % de pacientes bien alimentados y un 50,0 % con algún grado de desnutrición. El riesgo de sarcopenia fue del 28,6 %. Hubo diferentes correlaciones entre el puntaje SARC-CalF y las variables antropométricas (p < 0,05) según la etapa de la vida (adultos y ancianos). Después del análisis de regresión lineal, las medidas que más influyeron en el puntaje SARC-CalF fueron la circunferencia muscular del brazo (CMB) y el espesor del músculo aductor del pulgar de la mano dominante (EMAPD) en los adultos, mientras que en los ancianos fueron el peso actual y elEMAPD (p < 0,05). Conclusión: el SARC-CalF identificó al 28,6 % de los pacientes con riesgo de sarcopenia y se asoció con el peso corporal y las variables antropométricas indicativas de reserva muscular en adultos y ancianos.

Effect of urinary sodium-to-potassium ratio change on blood pressure in participants of the longitudinal health of adults study - ELSA-Brasil.

To assess the effect of changing the sodium to potassium (Na/K) ratio on blood pressure at 4 years of follow-up.The measurements were carried out under identical conditions in two study periods (2008-2010 and 2012-2014). Urinary excretion of sodium and potassium (mmol/L) over 12 nocturnal hours was used to calculate the Na/K ratio and categorized by quintile. The 24-hour sodium and potassium intake was estimated using a validated equation. The mean BP was calculated from 3 measurements after 5 minutes of rest. Of the 15,105 participants at baseline, 14,014 completed the first follow-up. Participants without validated urine collection (n = 5,041), using antihypertensive medication (n = 3,860) at either time points or reporting bariatric surgery during follow-up (n = 45) were excluded. The differences between follow-up and baseline values were calculated for BP and the Na/K ratio. Analyses were stratified by sex and adjusted for confounding variables.Sodium intake did not change from baseline, but potassium intake increased by approximately 150 mg in both sexes (P < .001), with a consequent reduction of the Na/K ratio. The highest quintile of change in the Na/K ratio was associated with greater variation in BP. When adjusted for covariates, it is possible to observe an increase in SBP in women from the third quintile of the Na/K ratio, in men this increase was observed from the fourth quintile. However, for DBP this increase is observed from the third quintile in both men and women.Increase in SBP was observed in women from the third quintile of the Na/K ratio, in men this increase is observed from the fourth quintile. However, for DBP this increase is observed from the third quintile in both men and women. The Na/K ratio demonstrated a greater association in BP.

Factors associated with urinary sodium/potassium ratio in participants in the ELSA-Brazil study. / Fatores associados à relação sódio/potássio urinária em participantes do ELSA-Brasil.

This study aimed to identify sociodemographic factors associated with high estimated sodium/potassium ratio. A total of 15,105 participants were assessed, from 35 to 74 years of age, from a cohort of public employees (ELSA-Brazil). Socioeconomic data were collected with a questionnaire, and 12-hour nighttime urine samples were collected to estimate sodium and potassium intake. Sodium/potassium ratio was calculated in mmol/L and divided into tertiles: 1st tertile, corresponding to "low"; 2nd tertile for "medium"; and 3rd tertile for "high" sodium/potassium ratio. The proportions and means were compared according to the classification of tertiles in the sodium/potassium ratio, using chi-square test and analysis of variance (ANOVA). Crude and adjusted multinomial logistic regression models were tested, with the 1st tertile as the reference. Factors associated with sodium/potassium ratio were: male sex (OR = 1.78; 95%CI: 1.60-1.98); age 35 to 44 years (OR = 1.71; 95%CI: 1.33-2.19); incomplete elementary schooling (OR = 2.38; 95%CI: 1.78-3.18); and lower income (OR = 1.47; 95%CI: 1.26-1.73). Men, younger individuals, and those with less schooling and income showed higher mean sodium/potassium ratio.

Este estudo teve por objetivo identificar os fatores sociodemográficos associados à estimativa de alta relação de consumo de sódio/potássio. Foram avaliados 15.105 participantes, de 35 a 74 anos, de uma coorte de servidores públicos (ELSA-Brasil). Dados socioeconômicos foram coletados por meio de questionário e realizada coleta urinária de 12 horas noturnas para estimar o consumo de sódio e potássio. A relação sódio/potássio foi calculada em mmol/L e dividida em tercis: 1º tercil corresponde à "baixa" relação; 2º à "intermediária" e 3º tercil à "alta" relação sódio/potássio. Foram comparadas as proporções e médias segundo as classificações do tercil da relação sódio/potássio, utilizando-se os testes de qui-quadrado e análise de variância (ANOVA). Foram testados modelos brutos e ajustados de regressão logística multinomial, tendo como referência o 1º tercil. Os fatores associados à alta relação sódio/potássio foram: sexo masculino (OR = 1,78; IC95%: 1,60-1,98); indivíduos de 35 a 44 anos (OR = 1,71; IC95%: 1,33-2,19); Ensino Fundamental incompleto (OR = 2,38; IC95%: 1,78-3,18) e menor renda (OR = 1,47; IC95%: 1,26-1,73). Verificou-se que os homens, indivíduos mais jovens e de menor escolaridade e renda apresentaram médias mais elevadas da relação sódio/potássio.

El objetivo de este estudio fue identificar los factores sociodemográficos asociados a la estimación respecto a la alta relación de consumo de sodio/potasio. Se evaluaron a 15.105 participantes, de 35 a 74 años, dentro de una cohorte de servidores públicos (ELSA-Brasil). Se recogieron datos socioeconómicos mediante un cuestionario y se realizó una toma nocturna de orina de 12 horas para estimar el consumo de sodio y potasio. La relación sodio/potasio se calculó en mmol/L y se dividió en terciles: 1er tercil corresponde a la "baja" relación; 2º tercil a la "intermedia" y 3er tercil a la "alta" relación sodio/potasio. Se compararon las proporciones y medias, según las clasificaciones del tercil de la relación sodio/potasio, utilizando los testes de chi-cuadrado y análisis de variancia (ANOVA). Se utilizaron modelos brutos y ajustados de regresión logística multinomial, teniendo como referencia el 1er tercil. Los factores asociados a la alta relación sodio/potasio fueron: sexo masculino (OR = 1,78; IC95%: 1,60-1,98); individuos de 35 a 44 años (OR = 1,71; IC95%: 1,33-2,19); enseñanza fundamental incompleta (OR = 2,38; IC95%: 1,78-3,18) y menor renta (OR = 1,47; IC95%: 1,26-1,73). Se verificó que los hombres, individuos más jóvenes y con menor escolaridad y renta presentaron medias más elevadas en la relación sodio/potasio.

Association of Adductor Pollicis Muscle Thickness and Handgrip Strength with nutritional status in cancer patients.

BACKGROUND AND AIM: Malnutrition is common in patients with cancer, and its early diagnosis can reduce or prevent further complications and improve the clinical and nutritional prognosis. Adductor Pollicis Muscle Thickness (APMT) and Handgrip Strength have been explored in this population to identify a reduction in strength and muscle mass prior to the use of conventional methods. We aimed to correlate APMT and Handgrip Strength with conventional anthropometric variables in cancer patients and verify their association with nutritional status as determined by the Patient-Generated Subjective Global Assessment (PG-SGA). METHODS: A cross-sectional study was conducted with 80 patients diagnosed with cancer who were candidates for surgery. Nutritional status was obtained from the PG-SGA. Conventional anthropometric measurements were taken, as well as APMT and Handgrip Strength. Pearson's correlation analysis and multivariate linear regression were applied to detect the influence of variables on APMT and HGS. A significance level of 5.0% was considered. RESULTS: A high prevalence of malnutrition and the need for dietotherapic intervention was found, identified by the PG-SGA. Correlations between APMT and Handgrip Strength with anthropometric variables and with the PG-SGA score were observed. After regression adjustments, the variables that interacted with APMT were TSF and AC, and the PG-SGA score, corrected Muscle Arm Area (CAMA), and age interacted with Handgrip Strength. CONCLUSION: Correlations between anthropometric measurements and the PG-SGA score with APMT and Handgrip Strength were observed, even after adjusting for age and sex. These associations demonstrate that APMT and Handgrip Strength can be used with criterion in patients with cancer as complementary methods to evaluate nutritional risk and the need for nutritional intervention.

[Sodium/potassium urinary ratio and consumption of processed condiments and ultraprocessed foods]. / Relación sodio/potasio urinario y consumo de condimentos industrializados y alimentos ultraprocesados.

INTRODUCTION: Introduction: one of the changes in diet is related to its content of sodium (Na) and potassium (K). Greater use of condiments and processed foods contributes to these changes and the Na/K ratio can be used as a marker of this consumption. Objective: to evaluate the association between Na/K ratio and consumption of industrialized condiments and ultra-processed foods. Methods: a sample of 150 adults underwent an anthropometric examination and answered the questionnaire on life habits, diet and health. Consumption of Na, K and salt was estimated by urinary excretion of 24 hours. Ultraprocessed consumption was estimated by 24-hour food registration. Na/K ratio divided into tertiles. Associations between ultraprocessed foods, use of industrialized condiments and Na/K ratio were tested. p < 0.05 was adopted. Results: the highest proportion was female (65%) and with a higher educational level (77%). Higher consumption of ultra-processed foods was observed in men, in those with higher schooling and in non-whites. Those who reported a frequent consumption of industrialized condiments showed a mean sodium of 4.1 ± 1.4 g/day (p = 0.03) and salt of 10.5 ± 3.6 g/day (p = 0.03). Among those who reported frequent use of industrialized condiments, a higher Na/K ratio was found and a lower ratio was observed among those with lower consumption of ultraprocessed foods. Hypertensive and those with salt intake above the recommended one presented higher Na/K ratio. Conclusion: frequent consumption of industrialized condiments is associated with higher salt excretion and Na/K ratio and higher consumption of ultraprocessed products increases Na/K ratio.

INTRODUCCIÓN: Introducción: uno de los cambios en la alimentación está relacionado con su contenido en sodio (Na) y potasio (K). El mayor uso de condimentos y alimentos industrializados contribuye a estos cambios y la relación Na/K puede ser utilizada como marcador de ese consumo. Objetivo: evaluar la asociación entre la relación Na/K y el consumo de condimentos industrializados y ultraprocesados. Métodos: la muestra estuvo compuesta por 150 adultos que fueron sometidos a examen antropométrico y respondieron al cuestionario sobre hábitos de vida, alimentación y salud. El consumo de Na, K y sal fue estimado por excreción urinaria de 24 horas y el consumo de ultraprocesados, por registro alimentario de 24 horas. La relación Na/K fue categorizada en terciles. Se probaron asociaciones entre alimentos ultraprocesados, uso de condimentos industrializados y relación Na/K. Se adoptó una p < 0,05. Resultados: la mayoría de los participantes era de sexo femenino (65%) y con alta escolaridad (77%). Se observó un mayor consumo de ultraprocesados entre los hombres, especialmente en los de mayor escolaridad y no blancos. Los individuos que relataron consumo frecuente de condimentos industrializados presentaron un mayor consumo de sodio (4,1 ± 1,4 g/día, p = 0,03) y sal (10,5 ± 3,6 g/día; p = 0, 03). Entre los que relataron uso frecuente de condimentos industrializados se encontró mayor relación Na/K y esta relación fue menor entre los de menor consumo de alimentos ultraprocesados. Los hipertensos y los participantes con un consumo de sal por encima de lo recomendado presentaron mayor relación Na/K. Conclusión: el consumo frecuente de condimentos industrializados está asociado a mayor excreción de sal y relación Na/K, así como el mayor consumo de ultraprocesados aumenta la relación Na/K.

Prospective Analysis of Food Consumption and Nutritional Status and the Impact on the Dietary Inflammatory Index in Women with Breast Cancer during Chemotherapy.

Considering the implications of adverse effects of chemotherapy (CT) and the potential impact of diet on patients' recovery, this study aimed to prospectively evaluate the association between the consumption of food groups, patients' Dietary Inflammatory Index (DII®) scores, and their nutritional status. Anthropometric and dietary assessments of 55 women with breast cancer (BC) were performed at three time points. T0 is the time point after the first CT cycle, T1 is the time point after the intermediate CT cycle, and T2 is the time point after the last CT cycle. We identified a significant increase in weight, body mass index, and waist circumference during CT. Consumption of poultry and eggs was higher in T1 when compared to T2, while consumption of total fruit and total vegetables was higher at T0 compared to T1 and T2. The diet became more pro-inflammatory over the course of treatment (X2(2) = 61.127), and was related to higher abdominal adiposity. Total fruit (T0: R2 = 0.208, T1: R2 = 0.095, T2: R2 = 0.120) and total vegetable consumption (T0: R2 = 0.284, T1: R2 = 0.365, T2: R2 = 0.580) predicted DII® change at the three-time points. Meanwhile, consumption of total grains was significantly associated only with T1 (R2 = 0.084) and T2 (R2 = 0.118), and consumption of simple sugars was significantly associated only with T0 (R2 = 0.137) and T1 (R2 = 0.126). Changes in food consumption led to an increase in the inflammatory profile of the diet, suggesting the necessity to improve the guidelines during and after CT. These results reinforce the need to promote healthier eating practices in concert with maintaining a healthy nutritional status in women with BC treated with CT.

Validation of single measurement of 12-hour urine excretion for estimation of sodium and potassium intake. A longitudinal study.

BACKGROUND: Evaluation of sodium and potassium intake can be carried out using different methods. Biological markers are able to capture intra and inter-individual variability and are used as separate measurements of consumption. The aim of this study was to test the validity of a single measurement of urinary sodium and potassium excretion as representative of habitual intake. DESIGN AND SETTING: Longitudinal study, federal university. METHODS: Food consumption data from a sample of adult university students and public servants (25 to 74 years old) were collected through 24-hour records and 12-hour urinary sodium and potassium excretion at five different times over a one-year period. The dietary data were entered into a nutritional research data software system and the sodium and potassium intakes were estimated. The variables were tested for normal distribution using the Kolmogorov-Smirnov test. One-way analysis of variance or the Kruskal-Wallis test was used to evaluate means. Correlations between measurements using Pearson or Spearman coefficients were calculated. The degree of agreement between the five measurements was given by the intraclass correlation coefficient. RESULTS: Satisfactory agreement was found between the five measurements of urinary sodium and potassium excretion over a year, with little variability in consumption. CONCLUSION: A single measurement of urinary sodium and potassium accurately estimated the usual average consumption of these electrolytes. This can be used in population-based studies.

Agreement between Graz Malnutrition Screening (GMS) with subjective nutritional assessment instruments in hospitalized patients.

BACKGROUND: it is essential for an early nutritional intervention that utilizes effective and practical nutritional screening and evaluation tools to diagnose nutritional status, increasing the patient's survival. OBJECTIVE: to evaluate the agreement of the Graz Malnutrition Screening (GMS) with subjective methods of nutritional evaluation in hospitalized patients. METHODS: descriptive cross-sectional study with adults and elderly of both sexes evaluated within 48 hours of hospital admission. Nutritional status in cancer patients was identified by the Patient-Generated Subjective Global Assessment (PG-SGA®) and in the elderly by the Mini Nutritional Assessment Short-Form (MNA-SF®). GMS was applied in both groups and its efficiency was compared with that of PG-SGA® and MNA-SF®. The agreement between the methods was evaluated by the kappa test, followed by assessment of diagnostic performance and correlation test. RESULTS: of the 87 patients evaluated, 64.4% (56) presented nutritional risk according to GMS, while 49.4% (43) and 47.1% (41) indicated nutritional risk and malnutrition according to MNA-SF® and PG-SGA®, respectively. GMS presented moderate agreement with PG-SGA®(p < 0.001) and MNA-SF® (p < 0.001), with high sensitivity, specificity,  positive predictive value, and negative predictive value. Correlations wereobserved between the GMS score and both the PG-SGA® (p < 0.001) and MNA-SF® scores (p < 0.001). CONCLUSION: GMS was effective in detecting nutritional risk in hospitalized patients when compared to classic tools in the evaluation of nutritionalstatus in hospitalized patients.

Hypertriglyceridemic waist phenotype and nutritional factors: a study with participants of ELSA-Brasil. / Fenótipo da cintura hipertrigliceridêmica e fatores nutricionais: um estudo com participantes do ELSA-Brasil.

OBJECTIVE: To investigate the association between fat and fiber intakes and the hypertriglyceridemic waist phenotype (HWP). METHODS: Cross-sectional survey conducted from the baseline of Brazilian Longitudinal Study of Health Adult (ELSA-Brasil). Anthropometric measurements were conducted and the body mass index was calculated (BMI). Participants were classified according to the presence of HWP when waist circumference ≥ 102 and ≥ 88 cm, respectively, in men and women, and triglycerides ≥ 150 mg/dL. Fat and fiber intakes were assessed using a validated food frequency questionnaire, and socioeconomic, demographic and behavioral variables were collected through a questionnaire. The χ² test, Mann-Whitney and Poisson regression were performed with significance level of 5%. RESULTS: There was no association between fiber and fat intakes with HWP. A lower prevalence of HWP among men was observed (IRR = 0.959; 95%CI 0.948 - 0.969). A higher prevalence of HWP was observed in participants with low physical activity (OR = 1.039, 95%CI 1.021 - 1.057), smoking history (OR = 1.044, 95%CI 1.031 - 1.057), lower per capita income (IRR = 1.035; 95%CI 1.022 - 1.049) and obesity (OR = 1.32, 95%CI 1.305 - 1.341). Fat and fiber intakes were not associated with HWP. CONCLUSION: A higher prevalence of HWP was found in obese, but no association was found between intake of fat and fiber and phenotype.

OBJETIVO: Investigar a associação entre consumo de gorduras e fibras e o fenótipo da cintura hipertrigliceridêmica (FCH). MÉTODOS: Pesquisa de corte transversal conduzida a partir da linha de base do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil). Foi realizada avaliação antropométrica e calculado o Índice de Massa Corporal (IMC). Os participantes foram classificados segundo presença do FCH quando circunferência da cintura ≥ 102 e ≥ 88 cm, respectivamente, em homens e mulheres, e triglicerídeos ≥ 150 mg/dL. O consumo de gorduras e fibras foi avaliado a partir de um Questionário de Frequência Alimentar validado e as variáveis socioeconômicas, demográficas e características comportamentais foram coletadas por meio de questionário. Foram realizados testes do χ2, Mann-Whitney e regressão de Poisson com significância de 5%. RESULTADOS: Homens apresentaram menor prevalência do FCH (RP = 0,959; IC95% 0,948 - 0,969). Maiores prevalências de FCH foram observadas em indivíduos com atividade física fraca (RP = 1,039; IC95% 1,021-1,057), histórico de tabagismo (RP = 1,044; IC95% 1,031-1,057), menor renda per capita (IRR = 1,035; IC95% 1,022-1,049) e obesidade (RP = 1,32; IC95% 1,305-1,341). Consumo de gorduras e fibras não foi associado ao FCH. CONCLUSÃO: Maior prevalência do FCH foi encontrada em obesos, porém não foi observada associação entre o consumo de gorduras e fibras e o fenótipo.
