ABSTRACT
Abstract Background Fatty acids are important components of diet that may influence the development of CVD. Objective To verify the relationship of dietary fatty acids with cardiometabolic markers in individuals at the cardiometabolic risk. Methods This cross-sectional study involved 282 subjects (116 M/166 F, 42 ± 16 years) attended the Cardiovascular Health Care Program, Universidade Federal de Viçosa (Brazil). Anthropometric and body composition measurements as well as metabolic and inflammatory markers were assessed by standard procedures. Demographic and lifestyle variables were obtained by semi-structured questionnaire. Food consumption was evaluated by 24h recall. Student's t-test or Mann-Whitney-U test and chi-square test were used, considering the statistical significance level of 5% probability. Results Individuals who eaten fat, fatty acids saturated and fatty acids polyunsaturated above recommendation (> 35, 7%, and 10% of caloric intake) were more likely to be overweight (p < 0.05). Those individuals with higher intake of medium-chain fatty saturated acids (≥ 1.05 g/d) had lower values (p < 0.05) of body mass index, waist circumference, waist-hip ratio and waist-height ratio and higher values (p < 0.05) of total leukocytes, C-reactive protein and total cholesterol, and LDL. Subjects with higher of palmitoleic acid intake (≥ 0.94 g/d) presented higher values of BMI, fat percentage and HOMA-IR (p < 0.05). Conclusion This cross-sectional study found different associations of dietary fat and cardiometabolic risk related to adiposity and inflammatory markers, according with chain-size and saturation, indicating the need the more detailed on the dietary assessment of obese patients to identify risk factors and established best strategies to control.

ABSTRACT Objective To assess the relationship between branched-chain amino acids intake in the current diet and the metabolic and body adiposity markers in a population at cardiovascular risk. Methods This is a cross-sectional study with 282 adults and elderly people from the Cardiovascular Health Care Program of the Universidade Federal de Viçosa. Sociodemographic, anthropometric and body composition data, as well as metabolic biomarkers were collected using standardized protocols. Dietary intake of branched amino acids was assessed using a 24-hour recall. Results Individuals with a higher branched-chain amino acids intake (≥2.6g/day, median value) had lower body fat (29.6 vs 32.2%; p=0.019), and higher serum ferritin (113.2 vs. 60.1mg/dL; p=0.006) and uric acid concentrations (4.4 vs. 4.0; p=0.023). In addition, a lower prevalence of overweight and excessive abdominal fat (p<0.05) was found in the individuals with higher branched-chain amino acids intake. They also had a higher daily intake of fiber, copper, zinc, magnesium, and iron, as well as a lower intake of total lipids. Conclusion In the present study, the intake of branched amino acids is negatively related to total and central adiposity, but more studies are needed to fully elucidate this possible relationship.

RESUMO Objetivo Avaliar a relação entre o consumo de aminoácidos de cadeia ramificada na dieta atual e os marcadores de adiposidade metabólica e corporal em uma população com perfil de elevado risco cardiovascular. Métodos Trata-se de um estudo transversal com 282 adultos e idosos do Programa de Atenção Cardiovascular da Universidade Federal de Viçosa. Dados sociodemográficos, antropométricos e de composição corporal, além de biomarcadores metabólicos, foram coletados utilizando protocolos padronizados. O consumo alimentar de aminoácidos ramificados foi avaliado através de um recordatório de 24 horas. Resultados Indivíduos com maior consumo de aminoácidos de cadeia ramificada (≥2,6g/dia, valor da mediana) apresentaram menores valores de gordura corporal (29,6 vs 32,2%; p=0,019) e maiores valores de séricos de ferritina (113,2 vs. 60,1mg/dL; p=0,006) e ácido úrico (4,4 vs. 4,0; p=0,023). Além disso, foi encontrada uma menor prevalência de sobrepeso e excesso de gordura abdominal (p<0,05) nos indivíduos com maior consumo de aminoácidos de cadeia ramificada. Eles também apresentaram um maior consumo diário de fibra, cobre, zinco, magnésio e ferro, além de um menor consumo de lipídios totais. Conclusão No presente estudo, o consumo de aminoácidos ramificados está negativamente relacionado à adiposidade total e central, porém mais estudos são necessários para elucidar completamente essa possível relação.

Resumo O objetivo deste estudo foi avaliar o consumo regular de bebidas açucaradas e sua associação com aspectos sociodemográficos e comportamentais de adultos de uma cidade do sudoeste brasileiro. Trata-se de um estudo de base populacional com 1226 adultos de 20 a 59 anos, residentes na zona urbana do município de Viçosa-MG. Foi aplicado um questionário estruturado para medir as condições sociodemográficas e comportamentais. O consumo de bebidas açucaradas foi classificado como regular quando a frequência de ingestão foi igual ou superior a cinco vezes por semana. O consumo regular de bebidas açucaradas foi superior em homens e mulheres com idade entre 20 e 29 anos (p < 0,01). Homens com hábito de realizar refeições em frente à televisão (p = 0,03) e mulheres insatisfeitas com seu peso (p = 0,03) apresentaram maior consumo regular de bebidas açucaradas. Conclui-se que os indivíduos de maior idade apresentaram menor consumo regular de bebidas açucaradas e este consumo esteve associado a comportamentos obesogênicos, como o hábito em realizar refeições em frente à televisão, e em indivíduos insatisfeitos com o peso corporal.
Abstract The aim of this study was to evaluate the regular consumption of sweetened beverages and its association with sociodemographic and behavioral aspects in a city in the southwest of Brazil. It involves is a population-based study of 1,226 adults aged 20 to 59 living in the urban area of the municipality of Viçosa in the state of Minas Gerais. A structured questionnaire to measure sociodemographic and behavioral conditions was applied. The consumption of sweetened beverages was considered regular when the frequency of consumption was five or more times a week. Regular consumption of sweetened beverages was higher in men and women aged between 20 and 29 years (p < 0.01). Men with the habit of eating meals in front of the television (p = 0.03) and women dissatisfied with their weight (p = 0.03) consumed greater regular amounts of sweetened beverages. The conclusion reached is that older individuals showed less regular consumption of sweetened beverages and that the consumption of same was associated with obesogenic behaviors, such as the habit of eating meals in front of the television and among individuals dissatisfied with their body weight.
