Introduction: Computerizd tomography (CT) is the gold standard for the evaluation of intra- (IAF) and total (TAF) abdominal fat; however, the high cost of the procedure and exposure to radiation limit its routine use. Objective: To develop equations that utilize anthropometric measures for the estimate of IAF and TAF in obese women with polycystic ovary syndrome (PCOS). Methods: The weight, height, BMI, and abdominal (AC), waist (WC), chest (CC), and neck (NC) circumferences of thirty obese women with PCOS were measured, and their IAF and TAF were analyzed by CT. Results: The anthropometric variables AC, CC, and NC were chosen for the TAF linear regression model because they were better correlated with the fat deposited in this region. The model proposed for TAF (predicted) was: 4.63725 + 0.01483 x AC - 0.00117 x NC - 0.00177 x CC (R-2 = 0.78); and the model proposed for IAF was: IAF (predicted) = 1.88541 + 0.01878 x WC + 0.05687 x NC - 0.01529 x CC (R-2 = 0.51). AC was the only independent predictor of TAF (p < 0.01). Conclusion: The equations proposed showed good correlation with the real value measured by CT, and can be used in clinical practice.

OBJETIVO: Comparar a viscosidade dinâmica da camada superficial da fáscia temporal com a de outros tecidos biológicos tradicionalmente utilizados em implantes de pregas vocais para o tratamento de rigidez de pregas vocais. DESENHO DO ESTUDO: Experimental. MÉTODO: Amostras de camada superficial da fáscia temporal, camada profunda da fáscia temporal e gordura abdominal de 12 cadáveres são submetidas a medição de viscosidade dinâmica. RESUTADOS: A viscosidade dinâmica das diferentes amostras apresenta-se na seguinte ordem crescente: camada superficial da fáscia temporal, camada profunda da fáscia temporal e gordura abdominal. Observa-se diferença estatística na comparação entre todas as amostras. DISCUSSÃO: Quanto maior for a viscosidade da mucosa da prega vocal, maior é a pressão subglótica necessária para se iniciar a fonação. Dessa maneira, um bom material implantável em lâmina própria de prega vocal deve ter baixa viscosidade. Por esse parâmetro, a camada superficial da fáscia temporal é um material promissor para implantação em pregas vocais. CONCLUSÃO: A viscosidade dinâmica da camada superficial da fáscia temporal é menor que a da camada profunda da fáscia temporal e que a da gordura abdominal.; OBJECTIVE: To compare the dynamic viscosity of superficial layer of temporalis fascia with that of other biological tissues traditionally used for vocal fold implants to treat vocal fold rigidity. STUDY DESIGN: Experimental. METHOD: Measurement of dynamic viscosity of samples of superficial layer of temporalis fascia...

Background: Previous studies have shown an association between adiposity, especially intra-abdominal adipose tissue, and hemodynamic/metabolic comorbidities in adults, however it is not clear in pediatric population. The aim of the study was to analyze the relationship between non-alcoholic fatty liver disease (NAFLD) and components of metabolic syndrome (MS) with values of intra-abdominal (IAAT) and subcutaneous (SCAT) adipose tissue in obese children and adolescents.Methods: Cross-sectional study. Subjects: 182 obese sedentary children and adolescents (aged 6 to 16 y), identified by the body mass index (BMI). Measurements: Body composition and trunk fat by dual-energy X-ray absorptiometry- DXA; lipid profile, blood pressure and pubertal stage were also assessed. NAFLD was classified as absent (0), mild (1), moderate (2) and severe (3), and intra-abdominal and subcutaneous abdominal fat thickness were identified by ultrasound. The MS was identified according to the cut offs proposed by World Health Organization adapted for children and adolescents. The chi-square test was used to compare categorical variables, and the binary logistic regression indicated the magnitude of the associations adjusted by potential cofounders (sex, age...

Cardiovascular diseases are a growing public health problem that affects most people over the age of 65 years and abdominal obesity is one of the risk factors for the development of these diseases. There are several methods that can be used to measure body fat, but their accuracy needs to be evaluated, especially in specific populations such as the elderly. The aim of this study was to assess the accuracy of anthropometric indicators to estimate the percentage of abdominal fat in subjects aged 80 years or older. A total of 125 subjects ranging in age from 80 to 95 years (83.5 ± 3), including 79 women (82.4 ± 3 years) and 46 men (83.6 ± 3 years), were studied. The following anthropometric indicators were used: body mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), and waist-to-height ratio (WHtR). The percentage of abdominal fat was measured by DEXA. Sensitivity and specificity were analyzed using an ROC curve. The sensitivity, specificity and AUC were 0. 578, 0. 934 and 0. 756 for BMI, respectively; 0.703, 0.820 and 0.761 for WC; 0.938, 0.213 and 0.575 for WHR, and 0.984, 0.344 and 0.664 for WHtR. BMI and WC were the anthropometric indicators with the largest area under the curve and were therefore more adequate to identify the presence or absence of abdominal obesity.; As doenças cardiovasculares são um problema crescente de saúde pública que afeta grande parte das pessoas acima de 65 anos...

Doutoramento em Motricidade Humana, especialidade de Saúde e Condição Física; One of the purposes of this dissertation was to analyze the usefulness of simple anthropometric measurements in predicting total body fat mass, as well as trunk and abdominal fat regions of interest, assessed by DXA, along with their changes in a weight loss program. Another purpose was to examine the influence of different physical activity dimensions on body weight, total body fat mass, abdominal and trunk fat regions of interest, selected by conventional whole body DXA in premenopausal overweight and obese women. Three studies were conducted within the PESO Program (Promotion of Exercise and Health in Obesity), a behavioural intervention addressed to premenopausal overweight and obese women. Key results show that: a) changes in lifestyle habits during a weight loss intervention may provide a stimulus to reduce trunk fat mass, with special focus on abdominal fat mass; b) abdominal circumference is a better predictor of body fat mass loss than waist circumference; c) baseline values of body weight, BMI, sagital diameter and hip circumference, are able to predict total body fat mass changes, but are unable to predict alterations in more specific depots of body fat estimated by DXA; d) alterations in DXA abdominal fat mass estimations were reasonably detected by all the anthropometric variables...

OBJECTIVES: To evaluate the reliability of the sagittal abdominal diameter and its validity as a predictor of visceral abdominal fat, as well as to identify the most appropriate cut-off points to identify the area of visceral fat that is known to represent a risk factor for cardiovascular disease. DESIGN: Validation study. SUBJECTS: 92 healthy volunteers (57 women, 35 men), age: 20-83 y, body mass index: 19.3 to 35.9 kg/m². MEASUREMENTS: Sagittal abdominal diameter (SAD), weight, height, circumferences (waist, hip, and thigh), sub-scapular skinfold thickness, abdominal diameter index, and waist-hip ratio (WHR). METHOD OF CHOICE: Computed tomography (CT). STATISTIC: Receiver operating characteristic (ROC) curve. RESULTS: The reliability for SAD measurement was very high (Inter-class coefficient = 0.99). Visceral fat as measured by VAF through CT was highly correlated with SAD (women r = 0.80; men r = 0.64, p < 0.001), waist circumference (women r = 0.77; men r = 0.73, p < 0.001), and WHR (women r = 0.72; men r = 0.58, p < 0.001). The ROC curve indicated 19.3 cm and 20.5 cm as the threshold values for abdominal sagittal diameter in women and men (sensitivity 85% and 83%, specificity 77% and 82%, respectively). CONCLUSIONS: There was a high correlation between SAD and VAF. The cut-off values identified for SAD presented a sensitivity and specificity that were considered adequate.

OBJECTIVE: To evaluate the impact of abdominal fat and insulin resistance on arterial hypertension of non-obese women. METHODS:Thirty-five non-obese women (NO), age 35-68 years were studied, and divided into two groups according to the presence of hypertension (BP > 140 x 90 mmHg) ( HT = hypertensive; NT = normotensive). Leptin measurement and oral glucose tolerance test (OGTT) to assess insulin were performed in these patients. A CT-scan was used to evaluate visceral (VF) and subcutaneous abdominal fat (SCF). The Central fat distribution index (CDI) was proposed to evaluate the impact of subcutaneous abdominal fat on central fat distribution in hypertensive patients. RESULTS: When compared to NT-NO (n = 17) group, HT-NO (n = 18) showed higher blood pressure levels (systolic and diastolic), greater VF area (84.40 ± 55.70 versus 37.50 ± 23.00 cm²; p = 0.036), greater SCF area (174.30 ± 83.00 versus 79.80 ± 27.40 cm²; p = 0.030), higher HOMAr index (1.59 ± 0.72 versus 0.93 ± 0.48 mmol.mU/L²; p = 0.006), higher CDI index (12.67 ± 7.04 versus 6.19 ± 2.57 cm²/kg) and higher leptin level (19.1 ± 9.6 versus 7.4 ± 3.5 ng/mL; p = 0.028). CONCLUSIONS: Arterial hypertension in non-obese women is associated with insulin resistance...

Two experiments were carried out to evaluate the performance, abdominal fat yield, and bone parameters of broiler chickens fed diets containing different lipid feedstuffs as energy source. During the starter phase (1 to 21 days) of Experiment 1, a completely randomized design with four treatments with eight replicates of 49 birds each one was applied. Broilers were fed starter diets formulated with different lipid sources: soybean oil (SO), cottonseed oil (CO), poultry offal oil (PO), and beef tallow (BT). During the finisher phase (21 to 42 days) of Experiment 1, each initial treatment was divided in two experimental groups: one fed the same fat ingredient as the previous period, and the other fed SO as energy source. Thus, during this period, a completely randomized design with seven treatments, four replicates, and 43 broilers per experimental unit was tested. During the starter phase (1 to 21 days) of Experiment 2, all broilers were fed with the same soybean oil-supplemented diet. The experimental groups were divided during the finisher phase (21 to 42 d) in a completely randomized design with five treatments groups with six replicates of 30 birds each. During this period, treatments consisted of diets formulated with SO, rapeseed oil (RO)...

Physical exercise seems to reduce abdominal fat, however new researches comparing different kind of exercises are needed to define efficient training programs. The purpose of the study was to compare the effects of the aerobic training and the resistance training on abdominal fat loss. Participants were 31 overweight women (mean age 44,5 ± 8,6 years) with high level of abdominal fat that do not practice regular physical exercise. The training program of the aerobic group (AG), 19 women, consisted of walking and running while the resistance group (RG), 12 participants, consisted of weight lifting exercises. During 10 weeks, participants of both groups (AG and RG) were required to attend three sessions of physical exercise per week. Body weight, height, waist circumference (WC), seven skinfold thickness were assessed and body max index (BMI) and body composition were calculated at baseline and after the exercise intervention. Reduces in WC, total body fat (%BF) and abdominal skinfold thickness (AbST) were statistically significant (p < 0.01) in both groups, despite no significant changes in body weight and BMI. RG showed a higher reduction in %BF (AG = 2.3%; RG = 3.1%), WC (AG= 1.9%; RG = 2.5%) and AbST (AG = 6.6%; RG = 6.8%), however there were no significantly differences between the values of the two training groups. In conclusion...

OBJECTIVE: To evaluate metabolic effects of epigallocatechin gallate (EGCG) supplementation when combined with a program of regular aerobic exercise in overweight/obese post-menopausal women. METHODS: Thirty-eight overweight or obese postmenopausal women exercised at moderate intensity, viz. walking three times per week for 45 min at 75% of age-predicted maximum heart rate (HR), and took a 150 mg capsule of EGCG (Teavigo) or placebo (lactose) twice daily for 12 weeks. Blood parameters (lipids, glucose and insulin), blood pressure, heart rate, arterial function and anthropometry were assessed at 0, 6 and 12 wk. At wk 0 and 12, body composition was assessed by dual energy X-ray absorptiometry (DXA) and abdominal fat was assessed by DXA and computed tomography (CT). RESULTS: Waist circumference (p < 0.01), total body fat (p < 0.02), abdominal fat (by DXA) (p < 0.01) and intra abdominal adipose tissue (by CT) (p < 0.01) were reduced in both treatment groups, with no difference between placebo and Teavigo. Teavigo significantly decreased resting HR (p < 0.01) and reduced plasma glucose in subjects with impaired glucose tolerance (p < 0.05). CONCLUSIONS: Moderate consumption of EGCG can improve the health status of overweight individuals undergoing regular exercise by reducing HR and plasma glucose concentrations. Loss of body fat...

Background and aims It is unclear whether high protein weight loss diets have beneficial effects on weight loss, abdominal fat mass, lipids, glucose and insulin compared to conventional low fat diets in subjects at increased risk of cardiovascular disease (CVD) because of elevated glucose and triglyceride concentrations. Our objective was to determine the effects of high protein (HP) compared to standard protein (SP) diets on CVD risk in obese adults. Methods and results Data from three, 12 week, randomized parallel trials with subjects assigned to either HP or SP diet (5500–6500 kJ/day) were pooled. Weight, body composition (dual energy X-ray absorptiometry), lipids, insulin and glucose were measured before and after weight loss. Data from 215 subjects (49.9 ± 9.8 years, BMI 33.5 ± 3.7 kg/m2), 108 HP, 107 SP were analyzed. Weight loss (HP diet 7.82 ± 0.37 kg; SP diet 7.65 ± 0.39 kg, NS) and total fat loss were not different (HP 6.8 ± 4.3 kg; LP 6.4 ± 4.7 kg, NS on intention to treat analysis). The reduction in triacylglycerol (TAG) was greater on HP than SP 0.48 ± 0.07 mmol/L vs 0.27 ± 0.06 mmol/L, (P < 0.001). Subjects with TAG greater than the median (>1.54 mmol/L at baseline) lost more weight (HP 8.5 ± 0.6; SP 6.9 ± 0.6 kg...

contribuindo para o aumento da gordura abdominal, e consequentes complicações metabólicas. O exercício físico permite quebrar este ciclo através da estimulação da lipólise e da utilização de ácidos gordos. Objetivo: Verificar os efeitos de um programa de exercícios no domicílio, em indivíduos com doença arterial coronária, na composição corporal, gordura abdominal, perfil lipídico, glicose, e nível de atividade física. Métodos: Estudo experimental composto por 20 indivíduos, aleatorizados grupo experimental (GE) e grupo de controlo (GC), ambos com 10, tendo o GE sido sujeito ao programa durante 8 semanas. Realizou-se uma avaliação inicial e final, através da bioimpedância, Tomografia Computorizada (TC) abdominal, perimetria, adipometria, análises sanguíneas e acelerómetro. Resultados: Numa análise intergrupal, verificouse uma diminuição da percentagem (%) de gordura total (GT) calculado pela adipometria (p<0.01), na prega supra-ilíaca (p=0.005), na prega abdominal horizontal (p=0.001) e vertical (p=0.003) no GE, e da % de tempo em atividades moderadas no GC (p=0.035). Após 8 semanas o GE diminuiu a %GT (p=0.008); a massa gorda (MG) (p=0.002); perímetro abaixo da última costela (p=0.037) e acima das cristas-ilíacas (p=0.021); %GT calculado (p=0.002); pregas supra-ilíaca (p=0.008)...

O excesso de gordura abdominal contribui no desenvolvimento de doenças crônicas não-transmissíveis. A absortometria de raio-X de dupla energia (AXDE) é uma técnica de simples aplicação, que permite a mensuração do percentual de gordura abdominal (%G abdominalAXDE). As medidas antropométricas, validadas e de baixo custo, como os perímetros abdominal 2,5cm acima da cicatriz umbilical (PAB2,5) e ao nível da cicatriz umbilical (PABum), são empregadas como indicadores de gordura abdominal. As dobras cutâneas (DC) são pouco estudadas nesse sentido. Assim, o objetivo desse estudo foi verifi car quais destes indicadores antropométricos mais se correlacionam e explicam o %G abdominalAXDE. A amostra foi composta por 22 mulheres (43,9±11,6 anos; 34,7±8,3 %G totalAXDE) e 18 homens (31,9±11,6 anos; 19,0±8,0 %G totalAXDE) submetidos à mensuração dos PAB2,5, PABum, DC suprailíaca (SI), axilar medial (AM), abdominal (AB), e %G abdominal (L1-L4) por AXDE. Correlação de Pearson e a regressão linear múltipla (método enter) foram empregadas para verifi car a correlação e o percentual de explicação das medidas antropométricas em relação ao %G abdominalAXDE. Correlações fortes e explicações signifi cativas (p<0,05) foram encontradas...

This is the final version of the article. It first appeared from BioMed Central via http://dx.doi.org/10.1186/s12889-015-2147-x; Background: Individuals of black ethnicity tend to have less visceral fat (VAT) but more subcutaneous-abdominal fat (SCAT) than white Caucasians. However, it is unclear whether such distribution of abdominal fat is beneficial for metabolic disease risk in black individuals. Here we examined the associations between these specific abdominal fat compartments and metabolic syndrome risk. Methods: 76 black South African young adults (36 men; 40 women) aged 18-19 years participating in the Birth to Twenty Cohort Study had VAT and SCAT measured by MRI. The metabolic syndrome traits (blood pressure, lipid profile, fasting glucose and insulin) were measured and the values were combined into a metabolic syndrome risk score. Results: Compared to men, women had greater VAT (mean: 16.6 vs. 12.5 cm2; p=0.005) and SCAT (median 164.0 vs. 59.9; p=0.0001). In men, SCAT (r=0.50) was more strongly related to the metabolic syndrome score than was VAT (r=0.23), and was independently associated with MetS (P=0.004) and HOMA-IR (P<0.001) after adjustment for VAT. In women, both abdominal fat compartments showed similar positive correlations with the metabolic syndrome score (r=0.26 to 0.31)...

150 pintos de um dia, machos, da linhagem comercial Hybro, foram submetidos, do nascimento até 3 semanas de idade, a 2 dietas experimentais. 75 aves receberam ração contendo elevado nível de gordura (HF) e as demais foram alimentadas com dietas sem suplementação de gordura (LF). De 3 a 6 semanas de idade, as aves foram alimentadas com as mesmas rações, adicionadas ou não de 0,1% de ácido acetilsalicílico (HF, LF, HFA e LFA). Todas as dietas utilizadas eram isocalóricas e isoprotéicas. Os pintos submetidos às rações de alto teor lipídico (HF) apresentaram peso corporal mais elevado, tanto às 3 como às 6 semanas de idade, porém as diferenças mostraram-se significativas apenas na 3a. semana. A porcentagem de gordura abdominal foi significativamente maior para as aves dos lotes de alta gordura, apenas às 6 semanas de idade. A inclusão de aspirina (1 g/kg) às rações propiciou diminuição significativa nos níveis de gordura abdominal e aumento do percentual de glicose sanguínea. A taxa de crescimento, a conversão e o consumo alimentares não foram significantemente reduzidos nas aves alimentadas com dieta contendo ácido acetilsalicílico, de 21 a 42 dias de idade.; One hundred fifty day-old Hybro male broiler chicks were fed from hatching to 3 weeks of age 2 isonitrogenous and isocaloric experimental diets. 75 birds were fed a high fat diet (HF) and the other half was fed a low fat diet (LF). Sixty birds of each treatment were assigned to 4 pens and fed 4 diets (HF...

OBJETIVO: Analisar a associação entre o consumo de bebidas alcoólicas e adiposidade abdominal. MÉTODOS: Estudo transversal com uma amostra de homens doadores de sangue (N=1.235), de 20 a 59 anos, em Cuiabá (MT), realizado de agosto/1999 a janeiro/2000. Os indicadores de adiposidade abdominal foram circunferência da cintura e relação cintura/quadril, ajustados pela adiposidade total. As medidas aferidas foram: peso, estatura, circunferências da cintura e do quadril. O consumo de álcool foi avaliado utilizando-se um questionário sobre tipo, freqüência e quantidade da bebida consumida. A associação entre o consumo de álcool e adiposidade abdominal foi analisada por regressão linear múltipla, com os modelos ajustados para idade, atividade física, tabagismo e adiposidade total. RESULTADOS: Após ajuste, a circunferência da cintura e a relação cintura quadril mantiveram-se associadas positivamente ao consumo de cerveja (p=0,02) e ao total de álcool consumido (p=0,01 e 0,03, respectivamente). O consumo de aguardente mostrou associação somente com a circunferência da cintura (p=0,04). CONCLUSÕES: O consumo de álcool, particularmente de cerveja, associou-se com a localização abdominal de gordura.; OBJETIVO: Analizar la asociación entre el consumo de bebidas alcohólica y adiposidad abdominal. MÉTODOS: Se efectuó estudio transversal con una muestra de hombres donadores de sangre (N= 1.235)...

DOI: http://dx.doi.org/10.5007/1980-0037.2013v15n5p561As doenças cardiovasculares são um problema crescente de saúde pública que afeta grande parte das pessoas acima de 65 anos, sendo a obesidade abdominal um dos vários fatores para o desenvolvimento dessas doenças. Existem vários métodos para mensurar gordura corporal, mas é necessário analisar a capacidade preditiva desses métodos, principalmente em algumas populações específicas como, por exemplo, os idosos. O objetivo do presente estudo foi analisar a capacidade preditiva de indicadores antropométricos na estimativa do percentual de gordura abdominal de idosos com 80 anos ou mais. Foram avaliados 125 idosos com idade entre 80 e 95 (83,5+ 3 anos), sendo 79 mulheres (82,4 ± 3 anos) e 46 homens (83,6 ± 3 anos). Utilizaram-se os indicadores antropométricos: Índice de Massa Corporal(IMC), Circunferência de Cintura(CC), Razão Cintura Quadril(RCQ) e Razão Cintura Estatura(RCEst), e o percentual de gordura de tronco foi mensurado por meio do DEXA. Foi realizada a análise de sensibilidade(SENS) e especificidade(ESP) mediante a curva ROC, e o IMC apresentou valores de SENS=0,578; ESP=0,934 e AUC= 0,756, a CC SENS= 0,703; ESP= 0,820 e AUC=0,761, a RCQ SENS=0,938; ESP=0...

http://dx.doi.org/10.5007/1980-0037.2008v10n3p283Excessive abdominal fat contributes to the development of chronic nontransmissible diseases. Dual emission X Ray absorptiometry (DXA) is a simple to administer technique that allows abdominal fat percentage (%abdominalFDXA) to be determined. Anthropometric measurements, which have been validated and are of low cost, such as the abdominal circumferences 2.5cm above the umbilical scar (ABC2,5) and level with the umbilical scar (ABCum), are used as indicators of abdominal fat. Skin folds (SF) are little used for this purpose. The objective of this study was to verify which of these anthropometric indicators best correlates with and best explains abdominalFDXA. The sample was made up of 22 women (43.9±11.6 years; 34.7±8.3 %G totalDXA) and 18 men (31.9±11.6 years; 19.0±8.0 %G totalDXA) who were measured for ABC2.5, ABCum, suprailiac SF (SI), midaxillary SF (AM) and abdominal SF (AB), while abdominalF (L1-L4) was measured by DXA. Pearson’s correlation and multivariate linear regression (“enter” method) were employed to verify the anthropometric measurements’ correlations and percentage of explanation with relation to abdominalFDXA. Strong correlations and significant levels of explanation (p<0.05) were observed for both women and men using ABC2.5 (0.90; 81% and 0.89; 78%)...

Introduction: Computerizd tomography (CT) is the gold standard for the evaluation of intra- (IAF) and total (TAF) abdominal fat; however, the high cost of the procedure and exposure to radiation limit its routine use. Objective: To develop equations that utilize anthropometric measures for the estimate of IAF and TAF in obese women with polycystic ovary syndrome (PCOS). Methods: The weight, height, BMI, and abdominal (AC), waist (WC), chest (CC), and neck (NC) circumferences of thirty obese women with PCOS were measured, and their IAF and TAF were analyzed by CT. Results: The anthropometric variables AC, CC, and NC were chosen for the TAF linear regression model because they were better correlated with the fat deposited in this region. The model proposed for TAF (predicted) was: 4.63725 + 0.01483 x AC - 0.00117 x NC - 0.00177 x CC (R² = 0.78); and the model proposed for IAF was: IAF (predicted) = 1.88541 + 0.01878 x WC + 0.05687 x NC -0.01529 x CC (R²=0.51). AC was the only independent predictor of TAF (p < 0.01). Conclusion: The equations proposed showed good correlation with the real value measured by CT, and can be used in clinical practice.
