Item Are Body Fat and Uric Acid associated with Cardiovascular Risk Scores? Cross-Sectional Analysis in the PROCARDIO-UFV Trial(International Journal of Cardiovascular Sciences, 2017-07) Rodrigues, Juliane Soares; Almeida, Alinne Paula de; Rosa, Carla de Oliveira Barbosa; Hermsdorff, Helen Hermana MirandaRisk scores are tools used to indicate the probability of occurrence of a certain cardiovascular event and to previously identify individuals at low, medium, and high risk for the development of cardiovascular diseases. To establish the cardiovascular risk of users of a cardiovascular health attention program of a university, and assess its association with lifestyle, clinical, sociodemographic data, and other cardiometabolic risk markers. Cross-sectional study with a sample of 197 participants. Demographic, anthropometric, clinical, and metabolic data, eating habits and lifestyle information were collected using the Global Risk Score and the Framingham Risk Score. P-value < 0,05 was considered statistically significant. According to the Framingham Risk Score, 84% of the assessed population was considered low risk and 16% as intermediate/high risk. However, according to the Global Risk Score, 18% of the participants were low risk, 45% were intermediate risk and 37% were high risk for infarction or death from coronary heart disease in 10 years. Excess body weight and uric acid serum levels showed to be significant cardiovascular risk markers in addition to those of the score and, consequently, they should be considered in clinical practice.Item Obesidade e a substituição de macronutrientes da dieta(Revista de Nutrição, 2001-05) Rosado, Eliane Lopes; Monteiro, Josefina Bressan ResendeOs fatores envolvidos na gênese da obesidade não são conclusivos, incluindo o papel dos macronutrientes da dieta na suscetibilidade ao ganho de peso. O carboidrato pode ser considerado um componente importante na saciedade. Sua substituição pelo adoçante, reduz o valor energético da dieta, reduzindo a massa corporal. Os efeitos dos adoçantes sobre o apetite dependem da natureza e da densidade dos nutrientes consumidos simultaneamente. Não existem evidencias suficientes que mostrem que os adoçantes causam ganho de peso, mas seu uso pode resultar em compensação energética com alimentos ricos em lipídios. Os lipídios tendem a aumentar a densidade energética da dieta promovendo o superconsumo passivo de energia, além de apresentar baixa prioridade oxidativa, estando associado à baixa saciedade. Sua substituição tem sido relacionada à compensação da ingestão energética, principalmente por carboidratos. Um plano alimentar disciplinado deve incluir alimentos que reduzam a densidade energética da dieta, sem promoção do consumo alimentar.Item Measurements of body fat distribution: assessment of collinearity with body mass, adiposity and height in female adolescents(Revista Paulista de Pediatria, 2015-01) Pereira, Patrícia Feliciano; Serrano, Hiara Miguel Stanciola; Carvalho, Gisele Queiroz; Ribeiro, Sônia Machado Rocha; Peluzio, Maria do Carmo Gouveia; Franceschini, Sylvia do Carmo Castro; Priore, Silvia EloizaTo verify the correlation between body fat location measurements with the body mass index (BMI), body fat percentage (BF%) and height, according to the nutritional status in female adolescents. A controlled cross-sectional study was carried out with 113 adolescents (G1: 38 with normal weight, but with high body fat level, G2: 40 with normal weight and G3: 35 overweight) from public schools in Viçosa-MG, Brazil. The following measures were assessed: weight, height, waist circumference (WC), umbilical circumference (UC), hip circumference (HC), thigh circumference, waist-to-hip ratio (WHR), waist-to-height ratio (WHtR), waist-to-thigh ratio (WTR), conicity index (CI), sagittal abdominal diameter (SAD), coronal diameter (CD), central (CS) and peripheral skinfolds (PS). The BF% was assessed by tetrapolar electric bioimpedance. The increase in central fat, represented by WC, UC, WHtR, SAD, CD and CS, and the increase in peripheral fat indicated by HC and thigh circumference were proportional to the increase in BMI and BF%. WC and especially the UC showed the strongest correlations with adiposity. Weak correlation between WHR, WTR, CI and CS/PS with adiposity were observed. The height showed correlation with almost all the fat location measures, being fair or weak with waist measurements. The results indicate colinearity between body mass and total adiposity with central and peripheral adipose tissue. We recommend the use of UC for assessing nutritional status of adolescents, as it showed the highest capacity to predict adiposity in each group, and also showed fair or weak correlation with height.Item Association of inflammation, dyslipidemia, obesity and physical activity status in children(Motriz: Revista de Educação Física, 2016-04) Pereira, Patrícia Feliciano; Oliveira, Michelle Dias de; Dias, Roberto Sousa; Paula, Sérgio Oliveira de; Guedes, Juliano Magalhães; Mamêde Neto, José Bontempo; Ribeiro Andaki, Alynne Christian; Natali, Antônio José; Rogério, Alexandre de Paula; Mendes, Edmar LacerdaThe aim of this study was to verify the association between inflammatory biomarkers, dyslipidemia, obesity and physical activity status in 10-years old children. Ninety-four children participated in this study and were classified into eutrophic (n=36), overweight (n=34) or obese (n=24) according to their body mass index (BMI). The genic expression of interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and chemokine C-C motif ligand 2 (CCL-2) mRNA; the serum concentration of high-density lipoprotein cholesterol (HDL-c) and triglycerides; BMI, percentage of body fat (% BF) and waist circumference; and the number of steps per day were determined. The expression of IL-6, TNF-α and CCL-2 were associated (p < 0.05) positively with serum triglycerides, BMI, % BF and waist circumference, and negatively with serum HDL-c. No association (p > 0.05) between pro-inflammatory biomarkers and number of steps per day was found.Item Effect of glycemic index on obesity control(Archives of Endocrinology and Metabolism, 2015-06) Pereira, Elisângela Vitoriano; Costa, Jorge de Assis; Alfenas, Rita de Cássia GonçalvesEvaluate the effect of glycemic index (GI) on biochemical parameters, food intake, energy metabolism, anthropometric measures and body composition in overweight subjects. Simple blind study, in which nineteen subjects were randomly assigned to consume in the laboratory two daily low GI (n = 10) or high GI (n = 9) meals, for forty-five consecutive days. Habitual food intake was assessed at baseline. Food intake, anthropometric measures and body composition were assessed at each 15 days. Energy metabolism and biochemical parameters were evaluated at baseline and the end of the study. Low GI meals increased fat oxidation, and reduced waist circumference and HOMA-IR, while high GI meals increased daily dietary fiber and energy intake compared to baseline. There was a higher reduction on waist circumference and body fat, and a higher increase on postprandial fat oxidation in response to the LGI meals than after high GI meals. High GI meals increased fasting respiratory coefficient compared to baseline and low GI meals. The results of the present study showed that the consumption of two daily low GI meals for forty-five consecutive days has a positive effect on obesity control, whereas, the consumption of high GI meals result has the opposite effect.Item Circunferência da cintura como indicador de gordura corporal e alterações metabólicas em adolescentes: comparação entre quatro referências(Revista da Associação Médica Brasileira, 2010) Peluzio, Maria do Carmo Gouveia; Franceschini, Silvia do Carmo Castro; Priore, Silvia Eloiza; Pereira, Patrícia Feliciano; Serrano, Hiara Miguel Stanciola; Carvalho, Gisele Queiroz; Lamounier, Joel AlvesAvaliar a validade diagnóstica de quatro tabelas de referência para circunferência da cintura em adolescentes do sexo feminino para detecção de alterações lipídicas, hiperinsulinemia, homeostasis model assessment (HOMA) elevado, hiperleptinemia e elevada adiposidade corporal. Avaliadas 113 adolescentes com idade entre 14 e 19 anos, provenientes de escolas públicas de Viçosa (MG). Em amostras de sangue foram dosados colesterol total, LDL, HDL, triglicerídeos, insulina e leptina. Determinado percentual de gordura corporal através de bioimpedância elétrica tetrapolar. Pela medida de menor diâmetro abdominal foi determinada a circunferência da cintura do abdômen e calculados valores de sensibilidade, especificidade, valor preditivo positivo e negativo. Foram elaboradas tabelas de contingência de classificação de circunferência da cintura em adolescentes para quatro critérios: Freedman et al., 1999; Taylor et al., 2000; McCarthy et al., 2001; e Moreno et al., 2007. Valores de sensibilidade em geral foram baixos para as referências avaliadas, sendo os maiores obtidos para a de McCarthy et al. Ao contrário, as especificidades foram altas, principalmente para a tabela de Freedman et al. Os valores preditivos positivos foram mais relevantes para colesterol total e percentual de gordura corporal.Os pontos de corte para circunferência da cintura de McCarthy et al. demonstraram-se os mais adequados para avaliações populacionais. A proposta de Freedman et al. por apresentar maior especificidade, é útil para uso clínico e pode substituir a realização de exames de custo elevado que em muitos locais não se encontram ao alcance dos profissionais de saúde, como leptina e insulina.Item Os efeitos do treinamento de força sobre os fatores de risco da síndrome metabólica(Revista Brasileira de Epidemiologia, 2008-03) Guttierres, Ana Paula Muniz; Marins, João Carlos BouzasMedidas não-farmacológicas, como a atividade física, vêm sendo recomendadas para prevenção e tratamento de doenças crônicas não transmissíveis.Realizar revisão da literatura para verificar os mecanismos por meio dos quais o treinamento de força provoca alterações metabólicas e celulares, agindo positivamente sobre os fatores de risco da síndrome metabólica. Foram utilizadas as bases de dados Medline, Scielo, Science Direct e Capes. A busca foi restrita aos últimos 10 anos. Os termos utilizados para pesquisa foram: obesity, dislipidemy,hypertension, diabetes mellitus, metabolic syndrome, resistance training, weight lifting, exercise.O treinamento de força atua sobre parâmetros metabólicos e celulares promovendo efeitos positivos no controle e na prevenção dos fatores de risco relacionados à síndrome metabólica, tais como diminuição do peso corporal, aumento da sensibilidade à insulina, aumento da tolerância à glicose, diminuição dos níveis pressóricos de repouso e melhoria do perfil lipídico.A revisão dos artigos científicos apresentados fornece dados que permitem concluir que o treinamento de força pode contribuir de forma efetiva na diminuição dos fatores de risco relacionados à síndrome metabólica.Item Dietary folate intake is negatively associated with excess body weight in brazilian graduates and postgraduates (CUME Project)(Nutrients, 2019-03) Pereira, Gabriela A.; Bressan, Josefina; Oliveira, Fernando Luiz P.; Sant’Ana, Helena Maria P.; Pimenta, Adriano M.; Lopes, Lílian L.; Hermsdorff, Helen Hermana M.Folate, vitamin B6, and vitamin B12 intake can be important regulators for obesity development. Thus, we investigated the possible association between the intake of these vitamins and the excess body weight or obesity prevalence in the participants of the Cohort of Universities in Minas Gerais (CUME project). This study analyzed cross-sectional data of 2695 graduates and postgraduates from universities in the state of Minas Gerais (801 men, 1894 women, ages 36.2 ± 9.4). The first step consisted of collecting data online, and the second step consisted of blood collecting in the subsample living in the city of Viçosa and its region (Minas Gerais). Excess body weight and obesity prevalence were 38.1% and 10.1%, respectively. Inadequate intake of folate, B6, and B12 were 12, 6.3, and 11.1%, respectively. Beans/lentils and French bread presented the highest contribution to folate intake (23.45% and 10.01%, respectively). Those individuals in the third tertile for folate intake (≥511.12 μg/d) had a lower excess body weight [prevalence ratio (PR): 0.79, confidence interval (CI): 0.71–0.8] and obesity prevalence (PR: 0.60, CI: 0.45–0.78). These associations were maintained when the sample was categorized by sex. In addition, serum folate was positively associated with dietary folate (p for trend = 0.032) and negatively associated with serum homocysteine (p for trend = 0.003) in the subsample. Dietary folate intake was negatively associated with excess body weight and obesity in CUME participants, indicating the relevance of this vitamin dietary assessment.Item Extruded sorghum consumption associated with a caloric restricted diet reduces body fat in overweight men: A randomized controlled trial(Food Research International, 2019-05) Cardoso, Leandro de Morais; Anunciação, Pamella Cristine; Alfenas, Rita de Cássia Gonçalves; Queiroz, Valéria Aparecida Vieira; Carvalho, Carlos Wanderlei Piler; Martino, Hércia Stampini Duarte; Pinheiro-Sant'Ana, Helena MariaThis study aimed to evaluate the effect of sorghum intake on body composition and metabolic variables in overweight men. In a randomized controlled crossover study, 24 overweight men (25.6 ± 4.6 years) were randomly allocated into one of two treatments: extruded sorghum or extruded wheat. The study consisted of 2 periods of 8 weeks with at least 4 weeks of washout. Anthropometric, clinical and metabolic risk variables were assessed at baseline and at the end of each intervention period. Extruded sorghum consumption reduced body fat percentage and increased daily carbohydrate and dietary fiber intake when compared to wheat consumption. Also, sorghum increased the serum glutathione peroxidase concentration, but no difference was observed when compared to wheat consumption. Extruded sorghum demonstrated to be a good alternative to control obesity in overweight men.Item Baseline pro-inflammatory diet is inversely associated with change in weight and body fat 6 months following-up to bariatric surgery(Obesity Surgery, 2019-02) Andrade, Patrícia Amaro; Hermsdorff, Helen Hermana M.; Leite, Jacqueline Isaura Alvarez; Shivappa, Nitin; Hébert, James R.; Henriques, Hirla Karen Fialho; Rosa, Carla de Oliveira BarbosaTo evaluate whether the baseline Dietary Inflammatory Index (DII®) was associated with weight loss and body composition change after bariatric surgery. This longitudinal study included 132 women with obesity (BMI ≥ 35 kg/m2, 43.0 ± 9.7 years), followed up for 6 months after bariatric surgery. The DII® was calculated from dietary data collected using 24-h dietary recall interviews. Anthropometric variables, socio demographic variables, health-related habits, history of disease, as well as gastrointestinal symptoms, both in the preoperative period (baseline) and 6 months after bariatric surgery were collected from the patients’ medical records. Individuals with a more pro-inflammatory diet (DII > 0.35 median value) preoperatively experienced smaller weight loss (− 22.7% vs. − 25.3%, p = 0.02) and fat mass loss (− 31.9 vs. − 36.2%, p = 0.026), with no difference in lean mass (p = 0.14). In a linear regression model, the baseline DII score was negatively associated with percentage change in weight and fat mass and positively associated with weight and fat mass in the sixth month after surgery. In addition, a pro-inflammatory baseline DII score was correlated with a lower intake of fruit (r = − 0.26, p = 0.006), vegetables (r = − 0.47, p = 0.001), and legumes (r = − 0.21, p = 0.003) in the postoperative period. In this longitudinal study, a pro-inflammatory diet at baseline was associated with smaller reductions in weight and body fat and poorer dietary quality (reduced consumption of fruits, vegetables, and legumes) 6 months after bariatric surgery.
