RESUMO

BACKGROUND AND AIM: Increased consumption of ultra-processed foods has been linked to both mortality and cardiovascular risk. Copeptin levels may serve as potential risk markers for cardiovascular death and events. This cross-sectional analysis seeks to assess the potential correlation between the intake of ultra-processed foods and copeptin levels in outpatients diagnosed with type 2 diabetes, based on estimates of cardiovascular risk. METHODS AND RESULTS: Outpatients underwent clinical and nutritional assessments. Dietary information was gathered using a validated quantitative food frequency questionnaire, and the consumption of all foods, beverages, and food products was assessed according to the NOVA food classification system. Fasting plasma-EDTA samples were collected and preserved at -80 °C. Plasma copeptin measurements were analyzed using an enzyme-linked immunosorbent assay based on the competition principle. Participants were categorized into two groups: high risk and very high risk, based on cardiovascular risk calculated by the HEARTS calculator. A total of 190 participants were included in the evaluation, with an average age of 60 ± 9 years, glycated hemoglobin of 8.4 ± 1.4%, and a diabetes duration of 11 (5-19) years. Patients at a very high cardiovascular risk exhibited higher plasma copeptin levels compared to those at high cardiovascular risk. Notably, 92.1% of patients reported consuming more than 10% of total energy intake from ultra-processed foods, although this proportion did not differ between the two groups. CONCLUSION: This patient sample reported elevated consumption of ultra-processed foods; nevertheless, the correlation between ultra-processed foods and plasma copeptin has not been substantiated.

RESUMO

OBJECTIVE: The objective was to evaluate the psychometric properties of the Mindful Eating Questionnaire (MEQ) in Brazilian subjects with type 2 diabetes mellitus (T2DM) and validate a Brazilian version of the MEQ for adults with T2DM (MEQ-DM). METHODOLOGY: Baseline data from the multicentre Nutritional Strategy for Glycaemic Control in Patients with Type 2 Diabetes Mellitus (NUGLIC) trial were used. Construct validity was assessed using exploratory factor analysis (EFA). The root mean square error of approximation (RMSEA), comparative fit index (CFI) and Tucker‒Lewis index (TLI) fit indices indicated the adequacy of the model. The reliability of the questionnaire was evaluated considering the different factor loadings. Criterion validity was tested by correlating the MEQ-DM with sociodemographic variables, body mass index (BMI) and physical activity levels. RESULTS: A total of 370 participants were included, who were mostly female (60.8 %) and had a median age of 61 (54-67) years. The EFA results supported the two-factor structure of the 25-item MEQ-DM: disinhibition and awareness. The results of the fit indices (RMSEA = 0.04; CFI = 0.95 and TLI = 0.94) and composite reliability (disinhibition = 0.84 and awareness = 0.81) were consistent. The criterion validity analysis indicated a significant association between MEQ-DM scores and age, sex, civil status, education level, BMI and physical activity (p < 0.05). CONCLUSION: When explored with Brazilian adults with T2DM, the MEQ-DM presented a factorial model with two dimensions: disinhibition and awareness. This model must be confirmed in future studies with Brazilians with T2DM.

RESUMO

Nutritional therapy should follow evidence-based practice, thus several societies regarding nutrition and critical care have developed specific Clinical Practice Guidelines (CPG). However, to be regarded as trustworthy, the quality of the CPG for critically ill patients and its recommendations need to be high. This systematic review aimed to appraise the methodology and recommendations of nutrition CPG for critically ill patients. We performed a systematic review (protocol number CRD42020184199) with literature search conducted on PubMed, Embase, Cochrane Library and other four specific databases of guidelines up to October 2021. Two reviewers, independently, assessed titles and abstracts and potentially eligible full-text reports to determine eligibility and subsequently four reviewers appraised the guidelines quality using the Advancing Guideline Development, Reporting and Evaluation in Health Care instrument II (AGREE-II) and AGREE-Recommendation Excellence (AGREE-REX). Ten CPG for nutrition in critically ill patients were identified. Only Academy of Nutrition and Dietetics and European Society of Intensive Care Medicine had a total acceptable quality and were recommended for daily practice according AGREE-II. None of the CPG recommendations had an overall quality score above 70 %, thus being classified as moderate quality according AGREE-REX. The methodological evaluation of the critically ill adult patient CPG revealed significant discrepancies and showed a need for improvement in its development and/or reporting. In addition, recommendations about nutrition care process presented a moderate quality.

RESUMO

OBJECTIVE: Fruits and vegetables contain many compounds presenting potential antioxidant activity. The objective of this study was to evaluate the effect of a green juice recipe in adult metabolism in order to identify new preventive dietary sources. METHOD: This was a single-blind randomized controlled clinical trial. Recruitment and data were, respectively, made and collected at the Universidade Federal de Ciências da Saúde de Porto Alegre. Individuals who met all the inclusion criteria during the period of recruitment were included. Green juice (experimental group) or placebo (control group) were consumed from Monday to Friday between 8 and 9 am, in the amount of 300 mL for 60 days (except Saturdays and Sundays). To verify the effect of green juice on metabolism, the following were evaluated: (a) glycemia, plasma lipid profile, renal and liver functions, redox profile, and antioxidant enzymes; (b) anthropometry; and (c) well-being and anxiety. RESULTS: This study included 14 participants in the test group (juice group) and 13 controls (placebo group), with mean ages of 31.07 and 30.15 years, respectively. We did not observe a significant difference between the treatments. Dietary properties of vegetable and fruit juices are an area of significant interest. CONCLUSIONS: Together with an analysis of previous works, we suggest that green juice did not cause an improvement in metabolic function and there is a need for further research on this issue, mainly through different interventions and other samples.

RESUMO

CONTEXT: Dietary interventions providing different amounts of carbohydrates have been proposed as a means of achieving glycemic control and weight loss in type 2 diabetes mellitus (T2DM); however, the supporting evidence is heterogeneous, making this recommendation difficult to apply in nutritional clinical practice. OBJECTIVE: The aim was to assess the quality of evidence from meta-analyses on low-carbohydrate (LC) dietary interventions for glycemic control, weight loss, and lipid profile in individuals with T2DM. DATA SOURCES: The MEDLINE, Web of Science, and Scopus databases were searched until September 2023. DATA EXTRACTION: A systematic review was conducted. Systematic reviews with meta-analysis of randomized clinical trials designed to assess glycated hemoglobin (HbA1c) reductions in individuals with T2DM were eligible. The AMSTAR-2 critical appraisal tool was used to evaluate the methodological aspects of all included studies. The GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach was used to assess the certainty of the evidence. DATA ANALYSIS: The LC interventions were associated with a reduction in HbA1c (%) of -0.42 (-1.45 to -0.09; high certainty of evidence) without considering follow-up time; at up to 3 months of follow-up of -0.28 (-0.13 to -0.43); at up to 6 months of follow-up of -0.40 (-0.61 to -0.09); at 6 to 12 months of follow-up of -0.32 (-0.49 to 0.11); and at >12 months of follow-up time of -0.31 (-0.14 to -0.65) compared with control diets. CONCLUSION: LC diets can help reduce HbA1c in individuals with T2DM in the short term (up to 3 months). However, dietary recommendations must always be individualized, as the studies reviewed herein analyzed different populations and used different definitions of what constitutes an LC diet. SYSTEMATIC REVIEW REGISTRATION: PROSPERO no. CRD42023404197.

RESUMO

Type 2 diabetes (T2DM), hypertension, and obesity are major contributors to global mortality. This study aimed to evaluate eating behavior and dietary practices among individuals with T2DM and/or hypertension, examining their associations with sociodemographic and anthropometric characteristics. We hypothesized that these factors may contribute to body mass index (BMI) and body fat (BF) levels in these individuals. In a cross-sectional study, adults/older individuals diagnosed with T2DM and/or hypertension were included. Eating behavior was evaluated via Three-factor Eating Questionnaire-R21. Dietary practices were assessed using the Dietary Guidelines for the Brazilian Population (DGBP) questionnaire. Poisson regression examined associations between eating behaviors, dietary practices, and sociodemographic factors. Linear regressions were employed to analyze relationships between eating behavior, dietary practices, BMI, and BF. The study included 275 primarily female (70.5%) participants under 60 years old (54.2%). Male and older participants had a lower prevalence of high scores in the 'emotional eating' (EE; PR: 0.40 [0.25;0.63]) and 'uncontrolled eating' (UE; PR: 0.68 [0.50;0.92]) domains. In contrast, older patients had a higher prevalence of adherence to the DGBP recommendations (PR:1.53 [1.20;1.94]). A positive association was observed between high EE (ß:3.71 [1.98;5.44]) and UE (ß:2.85 [1.15;4.55]) scores and BMI, whereas higher dietary practice scores (ß:-2.19 [-3.88;-0.50]) were negatively associated with BMI. High EE (ß:2.20 [0.38;4.02]) and UE (ß:1.92 [0.17;3.67]) scores were positively associated with BF regardless of the confounding factors included. Higher scores on the dietary practices were inversely associated with BF (ß:-1.94 [-3.67;-0.21]). Understanding dietary behaviors and practices can facilitate a more comprehensive and effective treatment approach.

RESUMO

Introduction: Introduction: the binge eating disorder (BED) is the eating disorder that most affects the obese population, and BED is an aspect that possibly interferes with the rate of adherence to nutritional treatment, which is also low in individuals with chronic non-communicable disease. Objective: to examine the relationship between adherence to dietary treatment and BED presence in obese individuals. Methods: this cohort study was conducted with a sample of 73 obese individuals at a nutrition and metabolic disease outpatient unit. Anthropometric data were collected, and a three-day food record was used for dietary assessment. BED was identified using the Binge Eating Scale, and patients were divided into two groups (BED and non-BED controls). Patients were reassessed at three-month follow-up. Data were analyzed using Student's t-tests and generalized estimating equations with Bonferroni correction. Adherence to dietary treatment was assessed by calculating differences between recommended and actual energy intakes. Results: BED was identified in 28.7 % of obese individuals. There was no significant difference in adherence to dietary treatment between BED and control patients. Both groups showed similar eating habits and physical activity levels throughout the study period. Conclusion: obesity is one of the factors contributing to the lack of adherence to nutritional guidelines. The importance of cognitive methods in dietary treatment programs should be further investigated.


Introducción: Introducción: el trastorno por atracón compulsivo (TA) es el trastorno alimentario que más afecta a la población obesa, y el TA es un aspecto que posiblemente interfiere en la tasa de adherencia al tratamiento nutricional, que también es baja en individuos con enfermedades crónicas no transmisibles. Objetivo: examinar la relación entre la adherencia al tratamiento dietético y la presencia de TA en individuos obesos. Métodos: este estudio de cohorte se realizó con una muestra de 73 personas obesas en una unidad de nutrición y enfermedades metabólicas ambulatorias. Se recogieron datos antropométricos y se utilizó un registro alimentario de tres días para la evaluación dietética. El trastorno por atracón compulsivo (BED, por sus siglas en inglés) se identificó usando la Binge Eating Scale, y los pacientes se dividieron en dos grupos (BED y controles sin BED). Los pacientes fueron reevaluados a los tres meses de seguimiento. Los datos se analizaron utilizando pruebas t de Student y ecuaciones de estimación generalizadas con corrección de Bonferroni. La adherencia al tratamiento dietético se evaluó calculando las diferencias entre la ingesta energética recomendada y la real. Resultados: se identificó BED en el 28,7 % de los individuos obesos. No hubo diferencias significativas en la adherencia al tratamiento dietético entre los pacientes con BED y los de control. Ambos grupos mostraron hábitos alimentarios y niveles de actividad física similares durante todo el periodo de estudio. Conclusión: la obesidad es uno de los factores que contribuyen a la falta de adherencia a las pautas nutricionales. La importancia de los métodos cognitivos en los programas de tratamiento dietético debe investigarse más a fondo.

RESUMO

CONTEXT: The type of dietary protein may modulate markers of diabetic kidney disease; however, no attempt to summarize the evidence from randomized controlled trials (RCTs) has been performed to date. OBJECTIVE: To assess the effects of different types of dietary protein on urinary albumin excretion and glomerular filtration rate in individuals with diabetes. DATA SOURCES: MEDLINE, EMBASE, and Scopus were searched for all published RCTs, with no language restriction, up to July 2020. DATA EXTRACTION: Study selection and data extraction were performed independently by 3 authors. Risk of bias was assessed independently by 2 authors, and the GRADE approach was used to assess the quality of the evidence. RESULTS: Twelve RCTs were included, of which 11 (involving 228 participants) were compiled in meta-analyses of random-effects models. Interventions consisted of diets emphasizing plant or white meat protein, with reduced intake of animal or red meat protein. Pooled data from crossover trials (n = 8) favored intervention diets for urinary albumin excretion (ratio of means, 0.86; 95% confidence interval 0.80 to 0.94; I2 = 4%) and glomerular filtration rate (ratio of means, 0.90; 95% confidence interval 0.87 to 0.94; I2 = 45%), compared with control diets. Results from parallel-design studies (n = 3), however, were not statistically significant for any outcome. The quality of the evidence ranged from very low to moderate, and most studies were judged with at least some concerns in terms of risk of bias. CONCLUSION: This meta-analysis found weak evidence for small to moderate improvements in markers of kidney function in favor of interventions with lower animal protein (or red meat protein) compared with usual diets in short-term crossover trials. These findings require confirmation in well-designed randomized controlled trials.

RESUMO

The prevalence of metabolic syndrome (MetS) is increasing worldwide, and diet therapy plays a key role in treating this disease. Since most patients show difficulties in adhering to nutritional interventions, research on the association of positive psychological characteristics with greater engagement in physical health is relevant to this field. The present study aimed to evaluate the association between positive psychology attributes (optimism, hope, self-esteem, positive/negative affect and life satisfaction) and changes in diet quality and anthropometric parameters of individuals with MetS who received nutritional counseling. The study assessed 63 patients at a nutrition outpatient clinic. Anthropometric parameters and 24-hour food recall data (for evaluation of the Brazilian Healthy Eating Index-Revised-BHEI-R) were collected at the first visit and subsequent return visit (on average five months later). Psychological data were collected at the first visit using validated and standardized scales. The results were adjusted in relation to the depression scores of the patients, which were evaluated using the Beck Depression Inventory-II (BDI-II). Changes in anthropometric factors and in the BHEI-R were assessed, and their associations with the psychological attributes were investigated. The results indicated that positive affect and hope were associated with improvement in the BHEI-R scores (Cohen effect sizes -0.65 and -0.58; p = 0.012 and 0.025, respectively). A significant association was also observed between optimism and a reduction in abdominal circumference (Cohen effect size 0.56; p = 0.031). The associations remained significant even after adjusting for the BDI-II scores (p = 0.022, p = 0.037 and p = 0.05, respectively). No statistically significant associations were observed for the other attributes assessed.The study suggests that some attributes may have a greater influence on the nutritional treatment of MetS and that future studies should be conducted in order to enable effective multidisciplinary interventions to treat MetS.

RESUMO

OBJECTIVE: To examine the relationships between obese patients with and without binge eating disorder (BED) and the neuropsychological profiles of their executive functions. METHODS: Data from 36 obese individuals (BMI ≥ 30 kg/m2) were divided into two groups, where one group was found to be positive for signs of BED according to the Binge Eating Scale. Two neuropsychological tests of executive function were carried out: the Go/No-go Task and the Iowa Gambling Task (IGT). Nutritional status was evaluated by measures of body weight, height and abdominal circumference, and from these, body mass indexes (BMI) were calculated. RESULTS: Both groups presented similar nutritional characteristics; there were no differences when it came to the health status of individuals with or without BED. Participants found positive for signs of BED had the lowest IGT scores (p = 0.004), and Go/No-go omission scores (p = 0.015) and commission scores (p = 0.04). Further statistically significant differences were also observed here between the two groups. Statistical differences in the IGT results correlated with BED, and were associated categorically (p = 0.005). CONCLUSION: Obese individuals frequently present deficits in selective attention, inhibitory control, decision-making and planning that can be directly related to binge eating and which is linked to BED. Nutritional status did not differ between the two groups studied, and did not show any connection with the disorder.

RESUMO

OBJECTIVE: To verify the knowledge about food and nutrition and its association with the nutritional status of obese patients with noncommunicable diseases (NCDs), and to identify the relationship between information sources and level of knowledge. METHOD: Cross-sectional study that included 263 outpatients of a cardiology referral hospital in Porto Alegre, Rio Grande do Sul, Brazil. The participants filled out a questionnaire on socioeconomic data and knowledge about food and nutrition and had their nutritional status evaluated by body mass index (BMI), waist circumference (WC) and waist-hip ratio (WHR). RESULTS: BMI showed a significant inverse association with the percentage of correct answers (p=0.002), as well as WC (p=0.000) and WHR (p<0.001). This was also true for education (p<0.001) and female gender (p=0.005) compared to males. More than 60% of patients reported using television and 23% reported using newspaper as sources of nutritional information. CONCLUSION: Our study revealed a significant association between BMI and the level of knowledge about foods, showing that there is need for more information on obesity-related NCDs for greater understanding by patients.

RESUMO

BACKGROUND: In Brazil, the prevalence of systemic arterial hypertension (SAH) is approximately 30% of the total population. In 2010, SAH was the cause of death of about 9.4 million people worldwide. A healthy dietary pattern is important to maintain proper blood pressure levels and, consequently, disease control. OBJECTIVES: To describe the knowledge and practices of hypertensive patients cared for at a public hypertension outpatient clinic, and its relationship with high-sodium food. METHODS: We applied a questionnaire to patients with questions related to sociodemographics, dietary pattern, frequency of ingestion of certain foods, and knowledge about their own disease. RESULTS: We studied 221 patients, 56.1% of whom were women, and 53.8% had only elementary education. Their mean age was 57.7 ±13.5 years, and 75.6% of them reported having high blood pressure, and 11.3%, diabetes mellitus. Regarding dietary pattern, 62% used ready-to-use seasonings, but 94.1% reported not adding extra salt to their ready meals. Regarding patients' knowledge about high-sodium foods and SAH, only 8 patients had 100% of right answers, 37 patients had 73.8%, and 42 patients, 57% of right answers. CONCLUSION: Knowledge about SAH prevention and high-sodium foods was insufficient. Based on this study's findings, more effective educational strategies targeted at this population can be developed.

RESUMO

There is a growing recognition that positive psychological functioning (which includes constructs such as optimism and hope) influences health. However, the understanding of these underlying mechanisms in relation to health is limited. Therefore, this review sought to identify what the scientific literature says about the influence of optimism and hope on chronic disease treatment. A search was conducted in the PsycINFO, Scopus, Pubmed, and Web of Science databases using the indexing terms optimism, hope, chronic diseases, randomized controlled trial, and treatment between 1998 and 2015. In the articles, we identified the most studied diseases in context, the assessment instruments used, the participant characteristics investigated, the results found, and the publication dates. From our analysis of the articles that met our inclusion criteria, it appears that the study of these constructs is recent and there is evidence that individuals with greater optimism and hope seek to engage in healthier behaviors, regardless of their clinical status, and that this contributes to chronic disease treatment. More research is needed so that targeted interventions can be carried out effectively in chronic disease treatment.

RESUMO

INTRODUCTION: prolactinomas are pituitary adenomas that express and secrete prolactin. These patients are overweight and the mechanisms are being studied. GOALS: assess nutritional and metabolic status of overweight patients with and without hyperprolactinemia caused by prolactinoma and compare them. MATERIALS AND METHODS: cross-sectional study, patients with body mass index (BMI) ≥ 25 kg/m2 with and without prolactinoma: 1) 20 normoprolactinemic (NPrl) with prolactinoma; 2) 23 hyperprolactinemic (HPrl) with prolactinoma; 3) 28 controls without prolactinoma or alterations in prolactin levels. Evaluated through anthropometric, dietetics, and biochemical assessment. RESULTS: of the 71 patients evaluated, most were obese women with macroprolactinomas. All three groups had diets with low caloric and monounsaturated fatty acid (MUFA) intake, the NPrl group had low carbohydrate (CHO) intake and high lipid (LIP) and saturated fatty acid (SFA) intake, and the NPrl and HPrl groups had appropriate intake of polyunsaturated fatty acids (PUFA). The HPrl group had elevated total cholesterol. HDL cholesterol was below the recommended threshold for most patients. No statistically significant differences were found in anthropometric and biochemical variables among the groups. CONCLUSIONS: most patients with prolactinomas and controls are obese and metabolically similar regardless of prolactin levels. All groups presented low caloric and MUFA intake. Protein, LIP, SFA, and cholesterol were significantly different among the groups, the NPrl group ingested less amount of protein and greater of fat. Snacking between meals and changes of food consumption on weekends was reported by most patients. This is the first study comparing patients with prolactinomas and controls, both with overweight, regarding food consumption and feeding behavior.


Introducción: los prolactinomas son adenomas hipofisarios que expresan y secretan prolactina. Estos pacientes tienen sobrepeso y el mecanismo está en estudio. Objetivos: evaluar el estado nutricional y metabólico de los pacientes con sobrepeso con y sin hiperprolactinemia causada por prolactinoma y compararlos. Materiales y métodos: es un estudio transversal con pacientes con índice de masa corporal (IMC) ≥ 25 kg/m2 con y sin prolactinoma: 1) 20 normoprolactinémicos (NPrl) con prolactinoma; 2) 23 hiperprolactinémicos (HPrl) con prolactinoma; 3) 28 controles sin prolactinoma o alteraciones en los niveles de prolactina. Evaluados a través de estudios antropométricos evaluación dietética y bioquímica. Resultados: de los 71 pacientes evaluados, la mayoría eran mujeres obesas con macroprolactinomas. Los tres grupos tenían dietas con baja ingesta de calorías y ácidos grasos monoinsaturados (MUFA), el grupo NPrl tenía ingesta baja en carbohidratos (CHO) y alta en lípidos (LIP) y ácidos grasos saturados (SFA), y los grupos NPrl y HPrl tenían ingesta apropiada de ácidos grasos poliinsaturados (PUFA). El grupo HPrl tenía el colesterol sérico por encima del valor recomendado, mientras el colesterol HDL estaba por debajo del valor recomendado en la mayoría de los pacientes. No se encontraron diferencias estadísticamente significativas en las variables antropométricas y bioquímicas entre los grupos. Conclusiones: la mayoría de los pacientes con prolactinomas y los controles son obesos y metabólicamente similares, independientemente de los niveles de prolactina. Todos los grupos presentaron baja ingesta de calorías y de ácidos grasos monoinsaturados. Proteínas, LIP, SFA y colesterol fueron significativamente diferentes entre los grupos, el grupo de NPrl ingiere menos cantidad de proteína y mayor de grasa. La mayoría de los pacientes manifiestan picar entre las comidas y cambios en el consumo de alimentos los fines de semana. Este es el primer estudio que compara a pacientes con prolactinomas y controles, ambos con sobrepeso, en cuanto a consumo de alimentos y comportamiento alimentario.

RESUMO

The relationship between shift work and the eatinghabits of workers was investigated in a slaughterhouse in southern Brazil. It involved a cross-sectional study with 1,206 workers of both sexes between 18 and 50 years of age. A standardized questionnaire was used to gather demographic, socioeconomic, work shift and eating habit information. The shift of work was categorized into daytime and nighttime, based on the starting and ending times of the shift. The eating habits of workers were evaluated as follows: number and type of meals eaten during the 24 hours of a normal day, the inappropriateness of the hoursof these meals and the dietaryrisk score. This was built on the risk score of the weekly consumption of 13 food items. After adjusting for potential confounders, non-Caucasian and younger male workers were more likely to manifest eating risk habits. Nighttimeshift workers consumed ahigher number of meals/day with greater inappropriateness of meal times than daytimeshift workers. The night shift can negatively influence the eating habits of workers of that shift.

RESUMO

CONTEXT AND OBJECTIVE: Osteoporosis is a skeletal abnormality characterized by reduction and alteration of bone microarchitecture that results in increased fragility and greater predisposition to fractures. Age and low bone mass are the main non-modifiable risk factors for osteoporotic fractures. The modifiable factors include sedentary lifestyle, inadequate calcium intake, excessive alcohol and/or caffeine consumption, smoking and low body weight. The aim here was to evaluate the association between low bone mass and calcium and caffeine intake among perimenopausal women in Southern Brazil. DESIGN AND SETTING: Cross-sectional study conducted in Porto Alegre and Canoas, Rio Grande do Sul, Brazil. METHODS: Women (n = 155) of mean age 53.6 ± 9.5 years were evaluated through a cross-sectional study in Southern Brazil. Food frequency questionnaires, bone mass evaluation using calcaneal ultrasound and anthropometric assessment were used. RESULTS: The prevalence of overweight was 67.7%. In the bone mass screening, 30.3% had low bone mass and 4.5% had osteoporosis. The median calcium intake was 574.94 mg/day and the caffeine intake was 108.11 mg/day. No association was found between bone mass and anthropometric parameters, calcium intake or caffeine intake. It was found that 38.4% of the women had low bone mass. CONCLUSIONS: No association was found between calcium and caffeine intake and bone mass. High prevalence of low bone mass was observed.

RESUMO

BACKGROUND: Cardiovascular diseases are one of the major causes of morbidity and mortality worldwide. In Brazil, they are the major cause of death. OBJECTIVE: To identify cardiovascular risk factors in parents/caregivers of children with heart diseases by assessing their nutritional status, health conditions, and life style. METHODS: Cross-sectional study of 150 parents or caregivers of children with heart diseases who attended a cardiology outpatient clinic. Data on identification, lifestyle and health conditions were collected by means of a structured questionnaire. For the assessment of the eating habits, a questionnaire on eating frequency was used; for the assessment of the nutritional status, weight, height, and waist circumference were measured, and the body mass index (BMI) was calculated and classified. RESULTS: A total of 155 parents of children with heart diseases, predominantly of the female gender (91.6%), were evaluated; their mean age was 35.0 ± 10.6 years. The most prevalent risk factors were sedentary lifestyle (85.2%), obesity (28%) and hypertension (22.6%). As regards the eating habits, a high frequency of intake of red meat, margarine, vegetable oil, and sugar and low intake of fish were observed. Comparison between genders showed a significant difference in relation to obesity, as detected by BMI, and hypertension, both more frequent among women. Waist circumference measurement also showed a higher cardiovascular risk in women. CONCLUSION: Cardiovascular risk factors such as excess weight, sedentary lifestyle, and hypertension as well as inadequate eating habits such as a high frequency of intake of saturated fat and cholesterol and low intake of unsaturated fat were identified in the parents/caregivers assessed.

RESUMO

Summary Objective: To verify the knowledge about food and nutrition and its association with the nutritional status of obese patients with noncommunicable diseases (NCDs), and to identify the relationship between information sources and level of knowledge. Method: Cross-sectional study that included 263 outpatients of a cardiology referral hospital in Porto Alegre, Rio Grande do Sul, Brazil. The participants filled out a questionnaire on socioeconomic data and knowledge about food and nutrition and had their nutritional status evaluated by body mass index (BMI), waist circumference (WC) and waist-hip ratio (WHR). Results: BMI showed a significant inverse association with the percentage of correct answers (p=0.002), as well as WC (p=0.000) and WHR (p<0.001). This was also true for education (p<0.001) and female gender (p=0.005) compared to males. More than 60% of patients reported using television and 23% reported using newspaper as sources of nutritional information. Conclusion: Our study revealed a significant association between BMI and the level of knowledge about foods, showing that there is need for more information on obesity-related NCDs for greater understanding by patients.


Resumo Objetivo: Verificar os conhecimentos sobre alimentação e nutrição e sua associação com o estado nutricional de pacientes obesos portadores de doenças crônicas, e identificar a relação das fontes de informação com o nível de conhecimentos. Método: Estudo transversal realizado com 263 pacientes ambulatoriais de um hospital de referência em cardiologia em Porto Alegre, RS. Os indivíduos preencheram um questionário sobre dados socioeconômicos e conhecimentos sobre alimentação e nutrição, tendo seu estado nutricional avaliado por meio de índice de massa corporal (IMC), circunferência da cintura (CC) e relação cintura quadril (RCQ). Resultados: O IMC apresentou associação inversa e significativa com o percentual de acertos (p=0,002), assim como a CC (p<0,001) e a RCQ (p<0,001). E também a escolaridade (p<0,001) e o sexo feminino (p=0,005) em relação ao masculino. Mais de 60% dos pacientes relataram utilizar televisão e 23% jornal como fontes de informação sobre alimentação. Conclusão: No presente estudo, houve associação significativa entre IMC e nível de conhecimento sobre alimentação, demonstrando que há necessidade de maior divulgação sobre as doenças crônicas não transmissíveis (DCNT) para que haja maior entendimento por parte dos pacientes.

RESUMO

Abstract Background: In Brazil, the prevalence of systemic arterial hypertension (SAH) is approximately 30% of the total population. In 2010, SAH was the cause of death of about 9.4 million people worldwide. A healthy dietary pattern is important to maintain proper blood pressure levels and, consequently, disease control. Objectives: To describe the knowledge and practices of hypertensive patients cared for at a public hypertension outpatient clinic, and its relationship with high-sodium food. Methods: We applied a questionnaire to patients with questions related to sociodemographics, dietary pattern, frequency of ingestion of certain foods, and knowledge about their own disease. Results: We studied 221 patients, 56.1% of whom were women, and 53.8% had only elementary education. Their mean age was 57.7 ±13.5 years, and 75.6% of them reported having high blood pressure, and 11.3%, diabetes mellitus. Regarding dietary pattern, 62% used ready-to-use seasonings, but 94.1% reported not adding extra salt to their ready meals. Regarding patients' knowledge about high-sodium foods and SAH, only 8 patients had 100% of right answers, 37 patients had 73.8%, and 42 patients, 57% of right answers. Conclusion: Knowledge about SAH prevention and high-sodium foods was insufficient. Based on this study's findings, more effective educational strategies targeted at this population can be developed.


Resumo Fundamento: No Brasil, a prevalência de hipertensão arterial sistêmica (HAS) é aproximadamente 30% do total da população. No mundo, HAS é a causa de morte de cerca de 9,4 milhões de pessoas. Um padrão alimentar saudável é importante para a manutenção de níveis pressóricos adequados e, consequentemente, controle da doença. Objetivos: Descrever o conhecimento e as práticas alimentares de pacientes hipertensos sobre a HAS, relacionando-a com alimentos ricos em sódio. Métodos: Aplicou-se aos pacientes um questionário contendo perguntas relacionadas ao seu padrão alimentar, hábitos e frequência de consumo de determinados alimentos e conhecimento sobre a doença e condições sociodemográficas. Resultados: Avaliaram-se 221 pacientes, sendo 56,1% mulheres, 53,8% com ensino fundamental incompleto, e média de idade de 57,7±13,5 anos. Desses, 75,6% referiram ser portadores de HAS e 11,3% eram diabéticos. Em relação ao padrão alimentar, verificou-se que 62% utilizam temperos prontos para o preparo das refeições, porém 94,1% referiram não adicionar sal à refeição pronta. Em relação ao conhecimento dos pacientes quanto aos alimentos com alto teor de sódio e à HAS, apenas 8 acertaram 100% das questões do questionário (14 acertos = 100%), 37 pacientes tiveram 73,8% de acertos e 42 pacientes, 57% de acertos. Conclusão: O conhecimento sobre prevenção da HAS e alimentos ricos em sódio foi considerado insuficiente. Com base nesses achados, será possível elaborar estratégias educativas mais efetivas e direcionadas para essa população.

RESUMO

BACKGROUND: Metabolic syndrome is associated with increased risk of cardiovascular events disease and type 2 diabetes. Treatment includes modifications on life style, diet and physical activity. Treatment adherence plays a crucial role in the successful treatment of this disease. OBJECTIVE: To evaluate two models of dietary intervention, and the relationship with adherence to treatment and impact on clinical improvement of patients with metabolic syndrome. METHODS: Randomized clinical trial, lasting four months. Participants were randomized assigned to the intervention or control group. Both groups were instructed to follow a diet for 4 months. Subjects in the intervention group additionally received an intervention package, with metabolic syndrome manual book, telephone counseling and nutrition education leaflets. In both groups nutritional anamnesis, anthropometric assessment, dietary assessment, individualized dietary and biochemical tests were done. RESULTS: Patients who arrived more motivated were those who has the greatest reduction in the values of body mass index, which decreased from 31.7 kg/m² (SD ± 3.9) to 30.9 kg/m² (SD ± 3.8), reduction in waist circumference was 108.1 cm (SD ± 9.8) to 105.9 cm (SD ± 9.5). The statistically significant associations were in the correlation between body mass index, blood glucose and triglycerides, reducing the consumption of whole milk, increased consumption of whole grains and skimmed milk and between the increase in vegetable intake and reducing triglycerides. CONCLUSION: Both groups showed significant improvement in all clinical parameters that was significantly associated with the previous motivation. Patients who arrived more motivated were those who responded better to treatment.
