Adequacy of Fatty Acids Consumption Among Individuals in Secondary Cardiovascular Prevention. / Adequação do Consumo de Ácidos Graxos entre Pacientes em Prevenção Cardiovascular Secundária.

BACKGROUND: Adhering to a diet adequate in macronutrients is crucial for the secondary prevention of cardiovascular diseases. OBJECTIVE: To assess the prevalence of adherence to recommendations for the consumption of dietary fatty acids for the prevention and treatment of cardiovascular diseases and to estimate whether the presence of certain cardiovascular risk factors would be associated with adherence. METHODS: Cross-sectional study using baseline data from 2,358 participants included in the "Brazilian Cardioprotective Nutritional Program Trial". Dietary intake and cardiovascular risk factors were assessed. Adequate intake of polyunsaturated fatty acids (PUFA) was considered as ≥10% of total daily energy intake; for monounsaturated fatty acids (MUFA), 20%; and for saturated fatty acids (SFA), <7% according to the Brazilian Society of Cardiology. A significance level of 5% was considered in the statistical analysis. RESULTS: No participant adhered to all recommendations simultaneously, and more than half (1,482 [62.9%]) did not adhere to any recommendation. Adherence exclusively to the SFA recommendation was the most prevalent, fulfilled by 659 (28%) participants, followed by adherence exclusively to the PUFA (178 [7.6%]) and MUFA (5 [0.2%]) recommendations. There was no association between the number of comorbidities and adherence to nutritional recommendations (p = 0.269). Participants from the Brazilian Northeast region showed a higher proportion of adherence to SFA consumption recommendations (38.42%) and lower adherence to PUFA intake (3.52%) (p <0.001) compared to other regions. CONCLUSIONS: Among the evaluated sample, there was low adherence to nutritional recommendations for dietary fatty acid consumption.

FUNDAMENTO: A adesão à uma alimentação adequada em macronutrientes é fundamental para a prevenção secundária de doenças cardiovasculares. OBJETIVO: Avaliar a prevalência de adesão às recomendações de consumo de ácidos graxos para prevenção e tratamento de doenças cardiovasculares, e estimar se a presença de determinados fatores de risco cardiovascular estaria associada à adesão. MÉTODOS: Estudo transversal com os dados de linha de base de 2358 participantes do estudo "Brazilian Cardioprotective Nutritional Program Trial". Dados de consumo alimentar, e fatores de risco cardiovascular foram avaliados. Foi considerada, de acordo com a Sociedade Brasileira de Cardiologia, uma ingestão adequada de ácidos graxos poli-insaturados (AGPI) ≥10% do consumo total de energia diária, para ácidos graxos monoinsaturados (AGM), 20% e para ácidos graxos saturados (AGS), <7%. Na análise estatística foi considerando nível de significância de 5%. RESULTADOS: Nenhum participante aderiu a todas as recomendações de forma simultânea e mais da metade (1482 [62,9%]) não aderiu a nenhuma recomendação. A adesão exclusivamente à recomendação de AGS foi a mais prevalente, sendo cumprida por 659 (28%) dos participantes, seguida da adesão exclusivamente à recomendação de AGP (178 [7,6%]) e de AGM (5 [0,2%]). Não houve associação entre o número de comorbidades e a adesão às recomendações nutricionais (p =0,269). Os participantes da região Nordeste do país apresentaram maior proporção de adesão às recomendações para consumo de AGS (38,42%), e menor para ingestão de AGPI (3,52%) (p <0,001) em comparação às demais. CONCLUSÕES: Na amostra avaliada, evidenciou-se baixa adesão às recomendações nutricionais para consumo de ácidos graxos.

Factors associated with diet quality among Brazilian individuals with cardiovascular diseases.

BACKGROUND: An individual's dietary pattern contributes in different ways to the prevention and control of recurrent cardiovascular events. However, the quality of the diet is influenced by several factors. The present study aimed to evaluate the quality of the diet of individuals with cardiovascular diseases and determine whether there is an association between sociodemographic and lifestyle factors. METHODS: This is a cross-sectional study carried out with individuals with atherosclerosis (coronary artery disease, cerebrovascular disease or peripheral arterial disease) recruited from 35 reference centres for the treatment of cardiovascular disease in Brazil. Diet quality was assessed according to the Modified Alternative Healthy Eating Index (mAHEI) and stratified into tertiles. For comparing two groups, the Mann-Whitney or Pearson's chi-squared tests were used. However, for comparing three or more groups, analysis of variance or Kruskal-Wallis was used. For the confounding analysis, a multinomial regression model was used. p < 0.05 was considered statistically significant. RESULTS: In total, 2360 individuals were evaluated: 58.5% male and 64.2% elderly. The median (interquartile range [IQR]) of the mAHEI was 24.0 (20.0-30.0), ranging from 0.4 to 56.0 points. When comparing the odds ratios (ORs) for the low (first tertile) and medium (second tertile) diet quality groups with the high-quality group (third tertile), it was observed that there was an association between diet quality with a family income of 1.885 (95% confidence intervals [CI] = 1.302-2.729) and 1.566 (95% CI = 1.097-2.235), as well as physical activity of 1.391 (95% CI = 1.107-1.749) and 1.346 (95% CI = 1.086-1.667), respectively. In addition, associations were observed between diet quality and region of residence. CONCLUSIONS: A low-quality diet was associated with family income, sedentarism and geographical area. These data are extremely relevant to assist in coping with cardiovascular disease because they enable an assessment of the distribution of these factors in different regions of the country.

Adiposity and insulin resistance mediate the inverse association between legume intake and blood pressure: a cross-sectional analysis in secondary cardiovascular prevention.

This study aimed to evaluate the association between legume intake and blood pressure, as well as the mediating role of cardiometabolic risk factors in patients in secondary cardiovascular prevention. Socio-demographic, anthropometric, clinical and food intake data were collected from the baseline of the multicentre study Brazilian Cardioprotective Nutritional Program Trial - BALANCE (RCT: NCT01620398). The relationships between variables were explored through path analysis. In total, 2247 individuals with a median age of 63·0 (45-91) years, 58·8 % (n 1321) male and 96·5 % (n 2168) with diagnosis of hypertension were included. Negative associations were observed between histidine intake and systolic blood pressure (SBP) (standardised coefficient (SC) = -0·057; P = 0·012) and between legume intake and BMI (SC = -0·061; P = 0·006). BMI was positively associated with triglycerides-glucose (TyG) index (SC = 0·173; P < 0·001), SBP (SC = 0·144; P < 0·001) and diastolic blood pressure (DBP) (SC = 0·177; P < 0·001), and TyG index was positively associated with DBP (SC = 0·079; P = 0·001). A negative indirect effect was observed between the intake of legumes, SBP and DBP, mediated by BMI (SC = -0·009; P = 0·011; SC = -0·011; P = 0·010, respectively). In addition, an indirect negative effect was found between the intake of legumes and the DBP, mediated simultaneously by BMI and TyG index (SC = -0·001; P = 0·037). In conclusion, legume intake presented a negative indirect association with blood pressure, mediated by insulin resistance (TyG) and adiposity (BMI) in individuals of secondary care in cardiology.

Effects of a Brazilian cardioprotective diet and nuts on cardiometabolic parameters after myocardial infarction: study protocol for a randomized controlled clinical trial.

BACKGROUND: Nut consumption has been related to improvements on cardiometabolic parameters and reduction in the severity of atherosclerosis mainly in primary cardiovascular prevention. The objective of this trial is to evaluate the effects of the Brazilian Cardioprotective Diet (DIeta CArdioprotetora Brasileira, DICA Br) based on consumption of inexpensive locally accessible foods supplemented or not with mixed nuts on cardiometabolic features in patients with previous myocardial infarction (MI). METHODS: DICA-NUTS study is a national, multicenter, randomized 16-week follow-up clinical trial. Patients over 40 years old with diagnosis of previous MI in the last 2 to 6 months will be recruited (n = 388). A standardized questionnaire will be applied to data collection and blood samples will be obtained. Patients will be allocated in two groups: Group 1: DICA Br supplemented with 30 g/day of mixed nuts (10 g of peanuts, 10 g of cashew, 10 g of Brazil nuts); and Group 2: only DICA Br. The primary outcome will consist of LDL cholesterol means (in mg/dL) after 16 weeks of intervention. Secondary outcomes will consist of other markers of lipid profile, glycemic profile, and anthropometric data. DISCUSSION: It is expected that DICA Br supplemented with mixed nuts have superior beneficial effects on cardiometabolic parameters in patients after a MI, when compared to DICA Br.

The effect of the a regional cardioprotective nutritional program on inflammatory biomarkers and metabolic risk factors in secondary prevention for cardiovascular disease, a randomised trial.

BACKGROUND & AIMS: To evaluate the effect of the Brazilian Cardioprotective Diet Program (BALANCE Program) on inflammatory biomarkers, involved in the pathophysiology of the atherosclerosis, on inflammatory biomarkers, cardiovascular risk factors, and on plasma fatty acids in cardiovascular disease secondary prevention patients. METHODS: In this substudy of the BALANCE Program randomized clinical trial, a total of 369 patients aged 45 years or older, who have experienced cardiovascular disease in the previous 10 years, were included. These patients were randomized into two groups and followed up for six months: BALANCE Program group and control group (conventional nutrition advice). In the initial and six-month final visits, anthropometry (body weight, height and waist circumference), food intake evaluation by 24-h dietary recall, plasma inflammatory biomarkers (IL-6, IL-8, IL-10, IL-12, tumor necrosis factor-α, adiponectin, and C-reactive protein levels), blood pressure, glycemia, insulinemia, lipid profile, and plasma fatty acids levels were evaluated. RESULTS: The BALANCE Program group showed increased plasma alpha-linolenic acid levels (P = 0.008), reduction in waist circumference (P = 0.049) and BMI (P = 0.032). No difference was observed among plasma inflammatory biomarkers and clinical data. CONCLUSION: After six months of follow-up, BALANCE Program led to a significant reduction on BMI and waist circumference in individuals in secondary prevention for cardiovascular disease. Although plasmatic alpha-linolenic acid has increased, there was no impact on plasma inflammatory biomarkers. CLINICAL TRIAL REGISTRATION: NCT01620398.

Ultra-processed foods consumption is associated with cardiovascular disease and cardiometabolic risk factors in Brazilians with established cardiovascular events.

The consumption of ultra-processed foods (UPF) has been associated with cardiometabolic risk factors. However, there is scarce literature on the association between UPF consumption, cardiovascular events, and cardiometabolic risk factors in subjects undergoing secondary care for cardiovascular diseases (CVD). Thus, we aimed to evaluate the association between UPF consumption, CVD, and cardiometabolic risk factors in subjects with established CVD. Baseline data from 2,357 subjects participating in a Brazilian multicenter study were analysed finding a mean UPF consumption of 18.7% of their energy intake. Higher figures of UPF consumption were founded associated with an increased presence of high waist circumference, overweight, peripheral arterial disease, and with a decreased odds of the simultaneous presence of coronary arterial disease, peripheral arterial diseases, and stroke when comparing among tertiles of UPF contribution to energy intake. These associations were observed when analyzing the whole sample and women but not men. Thus, these findings should help improve strategies for CVD patients in secondary care.

Dietary total antioxidant capacity is inversely associated with cardiovascular events and cardiometabolic risk factors: A cross-sectional study.

OBJECTIVES: Dietary total antioxidant capacity (dTAC) has been introduced as a useful tool to quantify the antioxidant content of a diet. However, few studies have evaluated the association of dTAC with cardiovascular disease (CVD) occurrence and cardiometabolic risk factors in people with established CVD events. Thus, we aimed to investigate the presence of an association between dTAC values, cardiovascular events, and cardiometabolic risk factors in individuals with previous CVD in a Brazilian multicenter study. METHODS: This study has a cross-sectional design. We evaluated baseline data from the Brazilian Cardioprotective Nutritional Program Trial. Sociodemographic, anthropometric, clinical, and food-consumption data were collected in face-to-face interviews. We estimated dTAC from the mean of two 24-h dietary recalls by values of ferric-reducing antioxidant power. RESULTS: We evaluated 2346 participants, most of whom were men (58.4%), older adults (64.2%), and overweight (68.6%), and had coronary artery disease (92.4%). The mean dTAC was equal to 5.6 (interquartile range, 3.9-7.8) mmol/1000 kcal. Participants in the third dTAC tertile (9.2 mmol/1000 kcal) had a 22%, 59%, and 69% lower chance, respectively, of having hypertriglyceridemic waist phenotype, abdominal aortic aneurysm, and amputation due to arterial disease in comparison to the first tertile (3.4 mmol/1000 kcal). CONCLUSIONS: The dTAC was inversely associated with hypertriglyceridemic waist phenotype, abdominal aortic aneurysm, and amputation due to arterial disease in individuals undergoing secondary care for CVD. Our results can guide strategies for the prevention of new CVD and its consequences.

Mindfulness Practice for Glycemic Control: Could it be a New Strategy for an Old Problem? A Systematic Review and Meta-Analysis.

BACKGROUND: The management of type 2 diabetes mellitus (T2DM) requires a complex and organized care that includes patient's lifestyle change. Additionally, emotional well-being is an important part of self-management, and it may impair the individual's adherence. Therefore, equipping the patients with the necessary coping and self-care techniques may be an important step in managing diabetes. OBJECTIVE: To evaluate the effect of interventions using established mindfulness-based protocols on glycemic control of individuals with T2DM. METHODS: Data sources: Two electronic databases (PubMed and EMBASE) were searched from inception to December 2019. We limited our search to published studies in English, Spanish and Portuguese languages. STUDY SELECTION: Randomized clinical trials that assessed the effects of mindfulness in individuals with T2DM were selected. DATA EXTRACTION: Two authors independently assessed the risk of bias and extracted data from the included trials. Data were pooled using inverse-variance random-effects meta-analyses. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. RESULTS: Four randomized trials were included. There were no differences in blood glucose change (mean difference between groups (MD) -0.73mg/dl; 95% CI, -10.49; 9.02; I2 =0%; very low quality of evidence) or glycated hemoglobin (MD 0.05%; 95%CI -0.22 to 0.32; I2 =29%; very low quality of evidence). CONCLUSION: Although the quality of current evidence is very low, our findings suggest that established protocols involving mindfulness have no effect on blood glucose or glycated hemoglobin in individuals with T2DM. Indeed, large-scale trials are needed to evaluate the contribution of mindfulness to glycemic control in clinical practice. PROSPERO Registration ID: RD42020161940.

Pro-inflammatory diet is associated with a high number of cardiovascular events and ultra-processed foods consumption in patients in secondary care.

OBJECTIVE: To evaluate the association of dietary inflammatory index (DII®) with the occurrence of cardiovascular events, cardiometabolic risk factors and with the consumption of processed, ultra-processed, unprocessed or minimally processed foods and culinary ingredients. DESIGN: This was a cross-sectional study that analysed the baseline data from 2359 cardiac patients. Data on socio-demographic, anthropometric, clinical and food consumption were collected. Energy-adjusted food intake data were used to calculate DII, and the foods were classified according to the NOVA classification. Furthermore, the patients were grouped according to the number (1, 2 or ≥ 3) of manifested cardiovascular events. The data were analysed using linear and multinomial logistic regression. SETTINGS: Multicentre study from Brazil. PARTICIPANTS: Patients with established cardiovascular events from the Brazilian Cardioprotective Nutritional Program Trial evaluated at baseline. RESULTS: Most of the patients were male (58·8 %), older adults (64·2 %) and were overweight (68·8 %). Patients in the third tertile of DII (DII > 0·91) had were more likely to have 2 (OR 1·27, 95 % CI: 1·01-1·61) and ≥ 3 (OR 1·39, 95 % CI: 1·07-1·79) cardiovascular events, with poor cardiometabolic profile. They also were more likely to consume a higher percentage of processed, ultra-processed and culinary ingredients foods consumption compared with the patients in the first DII tertile (DII ≤ 0·91). CONCLUSION: A more pro-inflammatory diet is associated with a greater chance of having 2 and ≥ 3 cardiovascular events and cardiometabolic risk factors and were more likely to consume processed, ultra-processed and culinary ingredients compared to those with a more anti-inflammatory diet.

Análise de custo-efetividade do Programa Alimentar Brasileiro Cardioprotetor (BALANCE): um estudo clínico randomizado, multicêntrico em indivíduos com doença cardiovascular / Cost-effectiveness analysis of the Brazilian Cardioprotective Diet Program (BALANCE): a randomized, multicenter clinical study in individuals with cardiovascular disease

O padrão alimentar associado à redução da mortalidade e de fatores de risco para doença cardiovascular inclui ingestão adequada de cereais integrais, frutas, leguminosas, legumes, nozes, sementes, peixe e consumo reduzido de carne vermelha e carne processada. Embora essa recomendação seja a melhor evidência do efeito benéfico entre dieta e doença coronariana, profissionais da saúde devem considerar que a disponibilidade e acessibilidade dos alimentos. O programa alimentar brasileiro cardioprotetor (BALANCE) é um estudo clínico randomizado que propõe a adoção de uma dieta com potencial cardioprotetor e acessível à população brasileira. Outras propostas de dietas cardioprotetoras foram feitas ao redor do mundo e mostraram ser eficazes na prevenção das doenças cardiovasculares e redução da mortalidade. No entanto, quando implementadas fora dos países de origem tornam-se impraticáveis pela baixa acessibilidade e adaptação cultural. Esta tese será apresentada sob a forma de três artigos científico. No primeiro foi realizada uma análise transversal do início do estudo BALANCE sobre o custo direto com despesas diárias alimentares e a qualidade da dieta. Não foi observada associação entre o custo direto e o índice de qualidade da dieta revisado (IQD-R), assim como não foi observada diferença entre a adesão aos escores do IQD-R. O segundo artigo realizou uma análise de custo-efetividade da alimentação adotada pelos participantes com maior adesão ao protocolo ao longo de 36 meses. Foram considerados apenas despesas diárias para a compra dos alimentos e a efetividade foi medida pelo IQD-R. Na linha de base, os custos médios foram iguais (U$ 3,9/dia) e o IQD-R foi de 53,5 e 51,8 pontos no nos grupos BALANCE e controle, respectivamente. Após um período de três anos, a intervenção foi associada a uma economia de custo média de US $ 0,31/dia (IC 95%: -0,59; -0,44) e um aumento médio do IQD-R de 4,38 (IC 95%: 2,81; 5,95). O terceiro artigo analisou o custo-efetividade do estudo BALANCE em todos os participantes, utilizando a perspectiva da sociedade e um horizonte temporal de 36 meses. Foram considerados custos diretos médicos (hospitalizações, procedimentos e exames) e custos diretos não médicos (gastos do paciente). Após 36 meses, a diferença no custo total entre as intervenções foi de -R$ 151,9 (IC 95%: -R$ 493,3; R$ 190,50). A dieta adotada pelo grupo BALANCE foi associada a uma economia média de R$ 415,53 (IC95% -687,79; -139,78). A diferença em LYs foi de 0,011 anos (IC 95%: -0,025; 0,046) de LYGs. A relação custo-efetividade incremental foi - R$ 14.098,63 por LYG (IC 95%: -156.178; 154.864). A análise de custo-efetividade do estudo BALANCE mostrou neutralidade em relação ao grupo controle. No entanto, o custo com a dieta adotada no grupo BALANCE foi menor ao longo do tempo e a melhor qualidade da dieta não se associou a maior despesa com alimentos. Esses achados podem estimular a adesão e recomendações da estratégia de educação nutricional BALANCE em um cenário de saúde pública.

The dietary pattern associated with reduced mortality and risk factors for cardiovascular disease includes adequate intake of whole grains, fruits, legumes, vegetables, nuts, seeds, fish and reduced consumption of red meat and processed meat. Although this recommendation is the best evidence of the beneficial effect between diet and coronary heart disease, healthcare professionals should consider food availability and accessibility. The Brazilian Cardioprotective Nutritional Program Trial (BALANCE Program) is a randomized clinical study that proposed a cardiovascular-protector diet suited for the Brazilian population. Other cardiovascular protector diets were implemented outside of Brazil and were shown to be effective for the prevention of cardiovascular diseases and the reduction of mortality rates, but became unfeasible when implemented outside their countries. This thesis is presented in the form of three papers. In the first, a cross-sectional analysis of the BALANCE trial baseline was performed, considering the direct cost of daily food expenses and the quality of the diet. There was no association between direct cost and Brazilian Health Eating Index Revised (BHEI-R), as well as with adherence to BHEI-R scores. The second article carried out a cost-effectiveness analysis of the food adopted by the participants with greater adherence to the protocol over 36 months. Only daily expenses for the purchase of food were considered, and effectiveness was measured by the BHEI-R. At baseline, the average costs were equal (U$3.9/day), and BHEI-R were 53·5 and 51·8 points, in the BALANCE Program and control groups, respectively. After a three-year period, the intervention was associated with an average cost saving of U$0·31/day (95%CI: -0·59; -0·04) and an average increase of BHEI-R of 4·38 (95%CI: 2·81; 5·95). The third article analyzed the cost-effectiveness of the BALANCE study with all participants, using the perspective of the society and a 36-month time horizon. Direct medical costs (hospitalizations, procedures and examinations), direct non-medical costs (patient expenses) and indirect costs (deaths) were considered. After 36 months, difference in total interventions cost was -R$151.9 (CI 95%: -R$ 493.3; R$190.50). The diet adopted by BALANCE group was associated with a mean cost saving of R$415.53 (CI95% -687.79; -139.78). Difference in LYs was 0.011 years (CI 95%: -0.025; 0.046) of LYGs. The incremental cost-effectiveness ratio was - R$ 14.098,63 per LYG (CI95%: -156.178; 154.864). Cost-effectiveness analysis from the BALANCE study showed neutrality compared to the control group. However, diet adopted in the BALANCE group saved money over time and better diet quality was not associated with higher food expenditure. This finding may encourage the adherence and recommendations of BALANCE nutritional education strategy in a public health scenario.

[Quality of diet and daily spending on food by adults with cardiovascular disease in Brazil]. / Qualidade da dieta e despesa diária com alimentação em adultos com doença cardiovascular no Brasil.

Adherence to a healthy diet depends on factors such as food prices, while studies in developed countries have identified higher costs of more nutritional foods. The current study aimed to assess the direct food expenditures by adults with cardiovascular disease in Brazil, investigating the relationship between cost and quality of diet. The study used data from a randomized clinical trial, the BALANCE Program. The current study is a cross-sectional baseline analysis of participants with high adherence to the trial, conducted in 35 sites in all five major geographic regions of Brazil. Food consumption by 1,160 individuals was collected with a 24-hour dietary recall (24HR), quality of diet was measured with the Diet Quality Index Revised (DQI-R), and direct food costs were estimated from market prices. No significant differences were observed between tertiles of adherence in the direct costs of food or individual characteristics. When all the 24HR were analyzed, there was no correlation between cost and quality of diet (r = 0.38; p = 0.17), while analysis by tertiles showed a weak correlation in the lowest tertile of adherence (r = -0.112; p = 0.03). The study showed absence of differences between direct costs of healthy versus unhealthy foods, a finding that can serve as an incentive for adherence to food recommendations in Brazil, thereby minimizing barriers to the adoption of healthy lifestyles.

A adesão a uma alimentação saudável depende de fatores como os preços dos alimentos, sendo que alguns estudos conduzidos em países desenvolvidos apontam para um maior custo de uma alimentação de melhor qualidade nutricional. O objetivo do presente trabalho foi avaliar o custo direto da alimentação de indivíduos adultos com doença cardiovascular no Brasil, investigando a relação entre o custo e a qualidade da dieta. Foram utilizados os dados de um ensaio clínico randomizado, o BALANCE Program. A investigação atual é uma análise transversal no momento inicial dos participantes com alta adesão ao estudo realizado em 35 centros das cinco regiões brasileiras. O consumo alimentar de amostra com 1.160 indivíduos foi coletado pelo recordatório alimentar de 24 horas (R24h), a avaliação da qualidade da dieta pelo Índice da Qualidade da Dieta Revisado (IQD-R) e os custos diretos da alimentação foram estimados por meio de preços de mercado. Não foram observadas diferenças significativas no custo direto da alimentação ou características dos indivíduos entre os tercis de adesão. Quando analisados todos os recordatórios não houve correlação entre custo e qualidade da dieta (r = 0,38; p = 0,17), já a análise por tercis mostrou fraca correlação entre o menor tercil de adesão (r = -0,112; p = 0,03). O presente estudo apontou ausência de diferenças entre os custos diretos da alimentação classificada como saudável e daquela com a pior qualidade nutricional, o que pode ser um incentivo à adesão às orientações alimentares no Brasil, minimizando barreiras à adoção de estilos de vida saudáveis.

Se utilizaron los datos de un ensayo clínico aleatorio, el BALANCE Program. La investigación actual es un análisis transversal desde el principio con participantes de alta adhesión al estudio, realizado en 35 centros de las cinco regiones brasileñas. El consumo alimentario de la muestra con 1.160 individuos fue recogido mediante el recordatorio alimentario de 24 horas (R24h), la evaluación de la calidad de la dieta se evaluó mediante el Índice de Calidad de la Dieta Revisado (IQD-R por sus siglas en portugués) y los costes directos de la alimentación se estimaron mediante precios de mercado. No se observaron diferencias significativas en el coste directo de la alimentación o características de los individuos entre los terciles de adhesión. Cuando se analizaron todos los recordatorios no hubo correlación entre coste y calidad de la dieta (r = 0,38; p = 0,17), ya en el análisis por terciles hubo una débil correlación entre el menor tercil de adhesión (r = -0,112; p = 0,03). El presente estudio apuntó una ausencia de diferencias entre los costes directos de la alimentación clasificada como saludable y aquella con peor calidad nutricional, lo que puede ser un incentivo para la adhesión a las orientaciones alimentarias en Brasil, minimizando barreras para la adopción de estilos de vida saludables.

Qualidade da dieta e despesa diária com alimentação em adultos com doença cardiovascular no Brasil / Quality of diet and daily spending on food by adults with cardiovascular disease in Brazil / Calidad de la dieta y gasto diario en alimentación de adultos con enfermedad cardiovascular en Brasil

A adesão a uma alimentação saudável depende de fatores como os preços dos alimentos, sendo que alguns estudos conduzidos em países desenvolvidos apontam para um maior custo de uma alimentação de melhor qualidade nutricional. O objetivo do presente trabalho foi avaliar o custo direto da alimentação de indivíduos adultos com doença cardiovascular no Brasil, investigando a relação entre o custo e a qualidade da dieta. Foram utilizados os dados de um ensaio clínico randomizado, o BALANCE Program. A investigação atual é uma análise transversal no momento inicial dos participantes com alta adesão ao estudo realizado em 35 centros das cinco regiões brasileiras. O consumo alimentar de amostra com 1.160 indivíduos foi coletado pelo recordatório alimentar de 24 horas (R24h), a avaliação da qualidade da dieta pelo Índice da Qualidade da Dieta Revisado (IQD-R) e os custos diretos da alimentação foram estimados por meio de preços de mercado. Não foram observadas diferenças significativas no custo direto da alimentação ou características dos indivíduos entre os tercis de adesão. Quando analisados todos os recordatórios não houve correlação entre custo e qualidade da dieta (r = 0,38; p = 0,17), já a análise por tercis mostrou fraca correlação entre o menor tercil de adesão (r = -0,112; p = 0,03). O presente estudo apontou ausência de diferenças entre os custos diretos da alimentação classificada como saudável e daquela com a pior qualidade nutricional, o que pode ser um incentivo à adesão às orientações alimentares no Brasil, minimizando barreiras à adoção de estilos de vida saudáveis.

Adherence to a healthy diet depends on factors such as food prices, while studies in developed countries have identified higher costs of more nutritional foods. The current study aimed to assess the direct food expenditures by adults with cardiovascular disease in Brazil, investigating the relationship between cost and quality of diet. The study used data from a randomized clinical trial, the BALANCE Program. The current study is a cross-sectional baseline analysis of participants with high adherence to the trial, conducted in 35 sites in all five major geographic regions of Brazil. Food consumption by 1,160 individuals was collected with a 24-hour dietary recall (24HR), quality of diet was measured with the Diet Quality Index Revised (DQI-R), and direct food costs were estimated from market prices. No significant differences were observed between tertiles of adherence in the direct costs of food or individual characteristics. When all the 24HR were analyzed, there was no correlation between cost and quality of diet (r = 0.38; p = 0.17), while analysis by tertiles showed a weak correlation in the lowest tertile of adherence (r = -0.112; p = 0.03). The study showed absence of differences between direct costs of healthy versus unhealthy foods, a finding that can serve as an incentive for adherence to food recommendations in Brazil, thereby minimizing barriers to the adoption of healthy lifestyles.

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

Background Complex percutaneous coronary intervention (PCI) is associated with higher ischemic risk, which can be mitigated by long-term dual antiplatelet therapy (DAPT). However, concomitant high bleeding risk (HBR) may be present, making it unclear whether short- or long-term DAPT should be prioritized. Objectives This study investigated the effects of ischemic (by PCI complexity) and bleeding (by PRECISE-DAPT [PRE dicting bleeding Complications in patients undergoing stent Implantation and Sub sequent Dual Anti Platelet Therapy] score) risks on clinical outcomes and on the impact of DAPT duration after coronary stenting. Methods Complex PCI was defined as ≥3 stents implanted and/or ≥3 lesions treated, bifurcation stenting and/or stent length >60 mm, and/or chronic total occlusion revascularization. Ischemic and bleeding outcomes in high (≥25) or non-high (<25) PRECISE-DAPT strata were evaluated based on randomly allocated duration of DAPT. Results Among 14,963 patients from 8 randomized trials, 3,118 underwent complex PCI and experienced a higher rate of ischemic, but not bleeding, events. Long-term DAPT in non-HBR patients reduced ischemic events in both complex (absolute risk difference: −3.86%; 95% confidence interval: −7.71 to +0.06) and noncomplex PCI strata (absolute risk difference: −1.14%; 95% confidence interval: −2.26 to −0.02), but not among HBR patients, regardless of complex PCI features. The bleeding risk according to the Thrombolysis In Myocardial Infarction scale was increased by long-term DAPT only in HBR patients, regardless of PCI complexity. Conclusions Patients who underwent complex PCI had a higher risk of ischemic events, but benefitted from long-term DAPT only if HBR features were not present. These data suggested that when concordant, bleeding, more than ischemic risk, should inform decision-making on the duration of DAPT. (AU)

Triglyceride-glucose index is associated with symptomatic coronary artery disease in patients in secondary care.

BACKGROUND: The triglyceride-glucose index (TyG index) is a tool for insulin resistance evaluation, however, little is known about its association with coronary artery disease (CAD), which is the major cardiovascular death cause, and what factors may be associated with TyG index. OBJECTIVE: To evaluate the association between the TyG index and the prevalence of CAD phases, as well as cardiovascular risk factors. METHODS: The baseline data of patients in secondary care in cardiology from Brazilian Cardioprotective Nutritional Program Trial (BALANCE Program Trial) were analyzed. Anthropometric, clinical, socio-demographic and food consumption data were collected by trained professionals. The TyG index was calculated by the formula: Ln (fasting triglycerides (mg/dl) × fasting blood glucose (mg/dl)/2) and regression models were used to evaluate the associations. RESULTS: We evaluated 2330 patients, which the majority was male (58.1%) and elderly (62.1%). The prevalence of symptomatic CAD was 1.16 times higher in patients classified in the last tertile of the TyG index (9.9 ± 0.5) compared to those in the first tertile (8.3 ± 0.3). Cardiometabolic risk factors were associated with TyG index, with the highlight for higher carbohydrate and lower lipid consumption in relation to recommendations that reduced the chance of being in the last TyG index tertile. CONCLUSION: The TyG index was positively associated with a higher prevalence of symptomatic CAD, with metabolic and behavioral risk factors, and could be used as a marker for atherosclerosis.

Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial.

BACKGROUND: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. METHODS: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. RESULTS: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ±â€¯8.4 vs 24.7 ±â€¯8.6, P < .01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P = .15). Secondary end points did not differ between groups after follow-up. CONCLUSIONS: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death.

Effects of oral supplementation with probiotics or synbiotics in overweight and obese adults: a systematic review and meta-analyses of randomized trials.

CONTEXT: Recent evidence suggests that modulation of the gut microbiota may contribute to body weight control. OBJECTIVE: This systematic review aimed to assess the effects of oral supplementation with probiotics or synbiotics on body weight, body mass index (BMI), and waist circumference in overweight and obese adults (BMI ≥ 25 kg/m2). DATA SOURCES: Five electronic databases-PubMed, Embase, Cochrane Library/CENTRAL, LILACS, and Web of Science-were searched from inception to August 2017. No language restrictions were applied. STUDY SELECTION: Randomized and quasi-randomized parallel trials that assessed the effects of oral supplementation with probiotics or synbiotics vs any other intervention but bariatric surgery or fecal transplantation in overweight or obese adults were selected. DATA EXTRACTION: Three teams of 2 authors independently assessed risk of bias and extracted data from the included trials. Data were pooled using inverse-variance random-effects meta-analyses. The quality of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. RESULTS: Nineteen randomized trials (28 publications, 1412 participants) were included. There were no differences in mean body weight change [mean difference (MD), -0.54 kg; 95%CI, -1.09 to 0.01; I2 = 0%; moderate quality of evidence) or mean BMI change (MD, -0.19 kg/m2; 95%CI, -0.43 to 0.04; I2 = 51%; low quality of evidence) between groups who received probiotics or synbiotics and control groups. Oral supplementation with probiotics or synbiotics reduced mean waist circumference compared with control (MD, -0.82 cm; 95%CI, -1.43 to -0.21; I2 = 46%; low quality of evidence). CONCLUSIONS: The findings suggest that oral supplementation with probiotics or synbiotics has a small effect to reduce waist circumference but no effect on body weight or BMI, although the quality of evidence is low to moderate. Therefore, the current evidence is not definitive. Large-scale trials are needed and may help to better inform clinical practice.
