“…Waist circumference (W) was defined as the smallest measurement between the lateral iliac crest and the lowest rib [8] with the patient in orthostatism and in expiration. Hip circumference (H) was measured at the level of the widest circumference over the great trochanters [8] . Skin fold thickness was determined at four sites (biceps, triceps, subscapular and suprailiac area) using a Lange caliper.…”

Aims: To compare the intra-abdominal fat thickness measured by ultrasound between HIV-infected patients treated or not with antiretroviral drugs and to correlate these visceral adiposity measurements to other parameters of cardiovascular risks. Methods: In a transversal observational study, 160 HIV-infected patients were recruited and divided in two groups, i.e., 123 antiretroviral (ARV)-treated and 37 ARV-naïve patients. These patients were submitted to anthropometric determinations, laboratorial analysis, ultrasonographic measurements of subcutaneous and intra- abdominal fat thickness and to tetrapolar bioelectrical impedance analysis in order to measure the body composition. Results: In the patients treated with highly active antiretroviral therapy (HAART) the intra-abdominal fat pad was significantly thicker than that of the untreated group (69 ± 21 mm, n = 123 vs. 60 ± 18 mm, n = 37; p = 0.03 Student’s t test). The intra-abdominal fat thickness correlated significantly with plasma triglyceride, total cholesterol, fasting glucose, glucose measurements 2 h after dextrose load, fasting insulin, HOMA-IR index, systolic and diastolic blood pressures, weight, BMI, WHR and caliper-measured total fat percentage. Conclusion: The results showed that antiretroviral therapy is associated with increased ultrasonographic measurements of visceral adiposity. Our data demonstrated a strong correlation between intra-abdominal fat thickness and independent risk factors of cardiovascular disease: atherogenic lipid profile and insulin resistance.

standardization deficiencies for its execution, limiting the comparison between different laboratories results' and its application in clinical practice 4 .Studies have correlated the isolated anthropometric measures and the anthropometric indexes with IR [5][6][7][8][9] . The anthropometric indicators arise as an alternative for IR's evaluation with lower cost and higher easiness of application in epidemiological studies and in health basic attention services. Because of the importance of this theme, the objective was to discuss about the main measures and the anthropometric indexes that have been associated with IR. MethodologyA bibliographic review was performed on available periodics in scientific bases, such as Scielo, Science Direct and Pubmed. The keywords used for the search of articles were: insulin resistance; anthropometry; body mass index; waist circumference; sagittal abdominal diameter; waist-hip ratio; conicity index; waist-thigh ratio; neck circumference; and waiststature ratio. Published articles were selected between 1990 and 2007, besides of the incorporation of classic previously published papers concerning the theme. Most of the studies included in this review were transversal. Some case-control and cohorts works were also discussed. Articles characterized by scientific rigidity, concerning the sample's size and statistical analysis appropriate to the objectives of the study. Insulin resistance Laboratorial determinationIR can be determined directly from the management of a predetermined quantity of exogenous insulin, or indirectly, based on the concentrations of endogenous insulin 10 .The euglycemic hyperinsulinemic clamp is an example of a direct technique that allows the determination of a metabolized insulin quantity, by the peripheric tissues during the stimulation with insulin. Although nowadays it is the golden standard technique for evaluating the IR in vivo, it is costly, slowly and of high complexity, being feasible its application in population studies, and especially in clinical practice AbstractSome studies have analyzed the efficacy of anthropometric indicators in predicting insulin resistance (IR), for they are more economic and accessible. In this study, the objective was to discuss the measures and anthropometric indices that have been associated with IR. A bibliographic review was done, based on Scielo, Science Direct and Pubmed. Among these studies, waist and sagittal abdominal diameter presented better predictive capacity for IR, with more consistent results. The waist-to-thigh, waist-to-size, neck-to-thigh ratios, the conicity and the sagittal index have showed positive results; nevertheless, more studies are necessary to consolidate them as predictors to IR. The obtained results, with the use of body mass index and of the waist-to-hip ratio, were inconsistent. In the Brazilian population, the realization of studies evaluating the performance of these indicators in predicting IR is suggested, since the results of the studies conducted in other populations are not always...

RESUMOObjetivo: Avaliar a associação entre bioimpedância elétrica (BIA) e gordura visceral (GV) em adultos e idosos. Sujeitos e métodos: Estudo transversal, 191 indivíduos (52% mulheres, 49% idosos), estratificados por sexo, grupo etário e massa corporal. Obtiveram-se dados sobre tomografia computadorizada (área de GV) e BIA (percentual de gordura corporal total (%GCT-BIA), ângulo de fase, reactância e resistência). Análise estatística: Coeficiente de Correlação de Pearson, Anova, Qui-quadrado de Pearson, Curva ROC. Resultados: Áreas de GV ≥ 130 cm 2 foram mais observadas em idosos e em homens. Entre as mulheres adultas, mostrou-se correlação mais forte entre GV e %GCT-BIA. Os demais grupos apresentaram resultados semelhantes e correlações estatisticamente significantes. As correlações entre GV e ângulo de fase foram fracas e sem significância estatística. As análises da Curva ROC indicaram os seguintes %GCT-BIA que identificaram excesso de GV: homens: 21,5% (adultos), 24,25% (idosos); mulheres: 35,05% (adultas), 38,45% (idosas), com sensibilidade de 78,6%, 82,1%, 83,3%, 66,7% e especificidade de 70,6%, 62,5%, 79,1%, 69%, respectivamente. Conclusão: BIA apresentou satisfatória sensibilidade e especificidade para predizer GV, entretanto, outros aparelhos e técnicas devem ser investigados para melhorar essa predição.Arq Bras Endocrinol Metab. 2013;57(1):27-32 Descritores Gordura visceral; impedância elétrica; tomografia computadorizada ABSTRACT Objective: To evaluate the association between electrical bioimpedance analysis (BIA) and visceral fat (VF) in adult and elderly patients. Subjects and methods: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly) stratified by sex, age and body mass. Computerized tomography (VF area) and BIA (percentage of total body fat (%TBF-BIA), phase angle, reactance and resistance) data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. Results: VF areas ≥ 130 cm 2 were more prevalent among the elderly and among men. Adult females showed a stronger correlation between GV and %TBF-BIA. The other groups showed similar results and statistically significant correlations. Correlations between GV and phase angle were weak and not statistically significant. ROC Curves analyzes showed the following %TBF-BIA, which identified excess VF: for male subjects: 21.5% (adults) and 24.25% (elderly); for female subjects: 35.05% (adults) and 38.45% (elderly) with sensitivity of 78.6%, 82.1%, 83.3%, and 66.7%, and specificity of 70.6%, 62.5%, 79.1%, and 69%, respectively. Conclusion: BIA was found to have satisfactory sensitivity and specificity to predict VF; however, other devices and other techniques should be investigated to improve VF prediction.
