Item Circunferência da cintura e relação cintura/estatura: úteis para identificar risco metabólico em adolescentes do sexo feminino?(Revista Paulista de Pediatria, 2011-09) Pereira, Patrícia Feliciano; Serrano, Hiara Miguel S.; Carvalho, Gisele Queiroz; Peluzio, Maria do Carmo G.; Franceschini, Sylvia do Carmo C.; Priore, Silvia Eloiza; Lamounier, Joel AlvesAvaliar se a medida da circunferência da cintura e a relação cintura/estatura (RCE) são preditoras de fatores de risco cardiovasculares em adolescentes do sexo feminino. Avaliaram-se 113 adolescentes de 14 a 19 anos quanto à antropometria (peso, estatura e circunferência da cintura), parâmetros bioquímicos e clínicos (colesterol total, LDL-C, HDL-C, triglicerídeos, glicemia de jejum, insulina, homeostasis model assessment to assess insulin resistance - HOMA-IR, leptina, homocisteína e pressão arterial). Considerou-se como ponto de corte de obesidade abdominal valores de cintura e RCE>percentil 90. As adolescentes com obesidade abdominal apresentaram valores significantemente maiores de triglicerídeos (exceto para a RCE), insulina, HOMA-IR, leptina, pressão arterial sistólica e diastólica; o HDL-C foi mais baixo no grupo com cintura >percentil 90, porém sem significância estatística (p=0,052). O presente estudo demonstrou que a cintura e a RCE são medidas úteis para identificar adolescentes do sexo feminino com maior risco cardiovascular; contudo, a circunferência da cintura, isoladamente, apresentou melhor desempenho.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 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 Medidas de localização da gordura corporal: uma avaliação da colinearidade com massa corporal, adiposidade e estatura em adolescentes do sexo feminino(Revista Paulista de Pediatria, 2015-01-24) 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 EloizaVerificar a correlação entre medidas de localização da gordura corporal com índice de massa corporal (IMC), percentual de gordura corporal (%GC) e estatura, de acordo com o estado nutricional em adolescentes do sexo feminino. Realizou‐se estudo transversal controlado, com 113 adolescentes (G1: 38 eutróficas mas com gordura corporal elevada; G2: 40 eutróficas e G3: 35 com excesso de peso), de 14 a 19 anos, de escolas públicas de Viçosa‐MG. Aferiu‐se peso, estatura, circunferência da cintura (CC), circunferência umbilical (CUm), circunferência do quadril (CQ), circunferência da coxa, relação cintura/quadril (RCQ), relação cintura/estatura (RCE), relação cintura/coxa (RCC), índice de conicidade (IC), diâmetro abdominal sagital (DAS), diâmetro coronal (DC), pregas cutâneas centrais (PCC) e periféricas (PCP). Avaliou‐se o %GC por bioimpedância elétrica tetrapolar. O aumento da gordura central, representada pela CC, CUm, RCE, DAS, DC e PCC, e o aumento da gordura periférica indicado pela CQ e da coxa foram proporcionais ao aumento do IMC e %GC. A CC e principalmente CUm apresentaram as correlações mais fortes com a adiposidade, enquanto RCQ, RCC, IC e PCC/PCP as mais fracas. A estatura apresentou correlação com praticamente todas as medidas de localização de gordura, sendo de fraca a regular com as medidas da cintura. Os resultados indicam colinearidade entre massa corporal e adiposidade total com tecido adiposo central e periférico. Recomenda‐se o emprego da CUm na avaliação do estado nutricional de adolescentes, pois ela apresentou maior capacidade para predizer adiposidade em cada grupo, além de correlação fraca a regular com a estatura.Item A pressão arterial está associada a indicadores de adiposidade corporal em crianças de quatro a sete anos(Revista Portuguesa de Cardiologia, 2017-07-24) Vieira, Sarah Aparecida; Fonseca, Poliana Cristina de Almeida; Andreoli, Cristiana Santos; Pereira, Patrícia Feliciano; Hermsdorff, Helen Hermana Miranda; Ribeiro, Andréia Queiroz; Priore, Silvia Eloiza; Franceschini, Sylvia do Carmo CastroEstudos feitos com adultos têm demonstrado associação entre aumento da adiposidade corporal e hipertensão arterial, mas ainda são escassos estudos que avaliaram essa associação na infância. O objetivo deste estudo foi investigar a associação entre pressão arterial e indicadores de adiposidade corporal em crianças, controlada por variáveis de nascimento, sociodemográficas, de estilo de vida e dietéticas.Estudo transversal com amostra de 399 crianças de quatro a sete anos. A variável dependente foi a pressão arterial, aferida de acordo com protocolo estabelecido pela VII Diretriz Brasileira de Hipertensão Arterial. As variáveis explicativas do estudo foram os índices relação cintura‐estatura (RCE) e índice de massa corporal (IMC). A regressão linear múltipla foi usada para avaliar a associação independente entre indicadores de adiposidade e pressão arterial, ajustada por variáveis de nascimento, sociodemográficas, estilo de vida e alimentação das crianças. Considerou‐se como significância estatística α = 5%.O IMC/I e a RCE correlacionaram‐se positivamente com a pressão arterial sistólica e diastólica. Após as análises múltiplas, os maiores valores de IMC (modelo 1) e RCE (modelo 2) se associaram ao aumento da pressão arterial sistólica e diastólica.O aumento da adiposidade corporal, avaliada pelo IMC e pela RCE, associou‐se ao aumento da pressão arterial sistólica e diastólica entre as crianças avaliadas. Assim, sugere‐se o uso do IMC e da RCE na avaliação nutricional de crianças, para screening de alterações na pressão arterial e outros fatores de risco cardiometabólico nessa população.Item Anthropometric indices to identify metabolic syndrome and hypertriglyceridemic waist phenotype: a comparison between the three stages of adolescence(Revista Paulista de Pediatria, 2014-10-14) Pereira, Patrícia Feliciano; Faria, Franciane Rocha de; Faria, Eliane Rodrigues de; Hermsdorff, Helen Hermana Miranda; Peluzio, Maria do Carmo Gouveia; Franceschini, Sylvia do Carmo Castro; Priore, Silvia EloizaTo determine the prevalence of metabolic syndrome (MS) and the hypertriglyceridemic waist phenotype (HW) in a representative adolescent sample; as well as to establish which anthropometric indicator better identifies MS and HW, according to gender and adolescent age. This cross sectional study had the participation of 800 adolescents (414 girls) from 10‐19 years old. Anthropometric indicators (body mass index, waist perimeter, waist/stature ratio, waist/hip ratio, and central/peripheral skinfolds) were determined by standard protocols. For diagnosis of MS, the criteria proposed by de Ferranti et al. (2004) were used. HW was defined by the simultaneous presence of increased waist perimeter (>75th percentile for age and sex) and high triglycerides (>100 mg/dL). The ability of anthropometric indicators was evaluated by Receiver Operating Characteristic curve. The prevalence of MS was identical to HW (6.4%), without differences between genders and the adolescence phases. The waist perimeter showed higher area under the curve for the diagnosis of MS, except for boys with 17‐19 years old, for whom the waist/stature ratio exhibited better performance. For diagnosing HW, waist perimeter also showed higher area under the curve, except for boys in initial and final phases, in which the waist/stature ratio obtained larger area under the curve. The central/peripheral skinfolds had the lowest area under the curve for the presence of both MS and HW phenotype. The waist perimeter and the waist/stature showed a better performance to identify MS and HW in both genders and in all three phases of adolescence.Item Waist-to-height ratio index or the prediction of overweight in children(Revista Paulista de Pediatria, 2017-11-17) Vieira, Sarah Aparecida; Ribeiro, Andréia Queiroz; Hermsdorff, Helen Hermana Miranda; Pereira, Patrícia Feliciano; Priore, Silvia Eloiza; Franceschini, Sylvia do Carmo CastroTo identify a low-cost abdominal adiposity index that has a higher accuracy in predicting excess weight in children aged four to seven years old. A cross-sectional study with a sample of 257 children aged 4 to 7 years old. Indicators of abdominal adiposity assessed were: waist circumference (WC), waist-to-height ratio (WHR) and central fat percentage (measured by dual energy X-ray absorptiometry - DEXA). Overweight children were classified using body mass index by age (BMI/age). In the analysis, the prevalence ratio (PR) using Poisson regression with a robust variance was estimated, and a receiver operating characteristic (ROC) curve was built, with a statistical significance of p<0.05. The prevalence of overweight children was 24.9% and a higher median of all abdominal adiposity indicators was observed in the overweight group. Children with increased values of WC (PR=4.1; 95%CI 2.86-5.86), WHR (PR=5.76; 95%CI 4.14-8.02) and a central fat percentage (PR=2.48; 95%CI 1.65-3.73) had a higher prevalence of being overweight. Using the ROC curve analysis, the WHR index showed a higher area under the curve, when compared to the WC and to the central fat percentage estimated by DEXA for predicting the classification of being overweight. Given the results, WHR is suggested for the screening of overweight children.Item Nutritional status, metabolic changes and white blood cells in adolescents(Revista Paulista de Pediatria, 2014-04-23) Oliveira, Thatianne Moreira Silva; Faria, Franciane Rocha de; Faria, Eliane Rodrigues de; Pereira, Patrícia Feliciano; Franceschini, Sylvia C.C.; Priore, Silvia EloizaTo analyze the relationship between the peripheral blood white cells, metabolic changes, and nutritional status of adolescents with and without excess weight and body fat. This cross-sectional study evaluated the body mass index (BMI) and percentage body fat (%BF) in 362 adolescents from 15 to 19 years of age, of both sexes. White blood cell count, platelet count, uric acid, fasting glucose, insulin, and lipid profile were measured. The inclusion criteria were agreement to participate in the study and signature of the informed consent. Exclusion criteria were: presence of chronic or infectious disease; use of medications that could cause changes in biochemical tests; pregnancy; participation in weight reduction and weight control programs; use of diuretics and laxatives; or the presence of a pacemaker. The following statistical tests were applied: Kolmogorov-Smirnov test, Student's t or Mann-Whitney test, Pearson or Spearman correlation tests, and chi-squared test, considering p<0.05. Overweight was observed in 20.7% of adolescents. The total cholesterol (TC) had a higher percentage of inadequacy (52.2%), followed by high-density lipoprotein (HDL) (38.4%). There was a positive correlation between white cells and serum lipids, insulin, body fat, and BMI. Monocytes were negatively correlated with BMI, and rods with BMI, body fat, and insulin. Nutritional status is related to an inflammatory process, and adolescents with excess weight or body fat presented higher amounts of white blood cells.Item Body composition, biochemical and clinical changes of adolescents with excessive adiposity(Arquivos Brasileiros de Cardiologia, 2012-04-12) Serrano, Hiara Miguel Stanciola; Carvalho, Gisele Queiroz; Pereira, Patrícia Feliciano; Peluzio, Maria do Carmo Gouveia; Franceschini, Sylvia do Carmo Castro; Priore, Silvia EloizaAdolescents with excess body fat and eutrophic had the same metabolic changes expected in obese individuals. To evaluate body composition, anthropometric changes, biochemical and clinical characteristics of female adolescents. A total of 113 adolescents from public schools in Viçosa, MG, divided into three groups: group 1 - consisting of eutrophic adolescents with excess body fat; group 2 - eutrophic with body fat within normal limits; and group 3 - with excess weight and body fat. Weight, height, waist and hip circumference, blood pressure were measured. The body mass index (BMI) and waist-hip ratio were calculated. The percentage of body fat was obtained by bioelectrical impedance horizontally, following its own protocol for this evaluation. The assessment of the percentage of body fat and biochemistry was performed after 12 hours of fasting, and analyzed the lipid profile, blood glucose and insulin, homocysteine, leptin and C-reactive protein. Insulin resistance was calculated by HOMA index. The group of eutrophic adolescents, with higher adiposity, behaved in relation to blood pressure, HDL and glucose levels, similarly to adolescents who are overweight. It can be seen that the HOMA index, insulin and leptin increased with increasing body fat. More than half of adolescents had total cholesterol and CRP levels above recommended levels. The most obvious metabolic disorder related to the lipid profile for both groups studied. Excess adiposity in normal weight adolescents may be related to clinical and biochemical changes similar to those found in adolescents who are overweight.Item Waist circumference as an indicator of body fat and metabolic disorders in adolescents: a comparison of four criteria(Revista da Associação Médica Brasileira, 2010-08-31) Pereira, Patrícia Feliciano; Serrano, Hiara Miguel Stanciola; Carvalho, Gisele Queiroz; Lamounier, Joel Alves; Peluzio, Maria do Carmo Gouveia; Franceschini, Silvia do Carmo Castro; Priore, Silvia EloizaTo evaluate the diagnostic validity of four waist circumference reference tables in female adolescents for detection of lipid abnormalities, hyperinsulinemia, high homeostasis model assessment (HOMA), hyperleptinemia, and high body adiposity. We evaluated 113 adolescents aged between 14 and 19 years enrolled in public schools of Viçosa (state of Minas Gerais, Brazil). Total cholesterol, LDL, HDL, triglycerides, insulin and leptin levels were measured. We also measured the percentage of body fat using tetrapolar bioelectrical impedance. Based on the measure of the smallest abdominal diameter, we defined the waist circumference and calculated sensitivity, specificity, positive and negative predictive values. Contingency tables for the classification of waist circumference in adolescents were developed for four criteria: Freedman et al., 1999; Taylor et al., 2000; McCarthy et al., 2001; and Moreno et al., 2007. Sensitivity values were generally low in the reference studies evaluated, and the highest values were found in the reference table by McCarthy et al. On the other hand, specificity values were high, especially for the table by Freedman et al. Positive predictive values were more relevant for total cholesterol and body fat percentage. The cutoff points for waist circumference provided by McCarthy et al. proved to be the most suitable for population studies. Because it has higher specificity, the proposal by Freedman et al. is useful for clinical use and can replace high cost tests, which are often unavailable for health professionals, such as those to measure leptin and insulin levels.
