          Abstract

          Abstract Background: relative fat mass (RFM) has been proposed recently, and the effectiveness in relation to other anthropometric indexes already consolidated regarding the predictive capacity of high blood pressure levels (HBPL) has not been investigated yet. Objectives: the objective was to analyze the predictive capacity of RFM for HBPL, and to compare it with others indexes. Methods: a cross-sectional study was conducted with 896 individuals. Weight, height, hip, waist circunference (WC), and neck circunference measurements were evaluated, and RFM, body mass index (BMI), body adiposity index, waist/hip ratio, and waist/height ratio were calculated. Systolic (SBP) and diastolic (DBP) blood pressures were measured on one occasion. Descriptive statistics, Pearson's correlation, a logistic regression model, and the analysis of the receiver operating characteristic (ROC) curves were used. Results: HBPL proportion was higher in men (34.68 %, p < 0.01). There was a positive correlation (p < 0.01) between all anthropometric measurements and SBP and DBP. WC in males (OR, 3.66; p < 0.01) and BMI in females (OR, 5.06; p < 0.01) showed the greatest associations with HBPL. There was no statistical difference (p > 0.05) in the area under the curve. Conclusions: the findings of our study suggest that RFM is not the best index for predicting HBPL, although it has shown positive associations.

          Resumen Introducción: se ha propuesto recientemente la medida de la masa grasa relativa (RFM) como predictor de la hipertensión arterial (HBPL), aunque su valor predictivo y la comparación con otros índices antropométricos está por evaluar. Objetivos: el objetivo fue analizar la capacidad predictiva de la RFM para el HBPL y compararlo con otros índices. Métodos: se realizó un estudio transversal con 896 individuos. Se evaluaron las medidas de peso, talla, cadera, circunferencia de la cadera (CC) y circunferencia del cuello, y se calcularon la RFM, el índice de masa corporal (IMC), el índice de adiposidad corporal, la relación cintura/cadera y la relación cintura/estatura. En una ocasión se midió la presión arterial sistólica (PAS) y diastólica (PAD); se utilizaron la estadística descriptiva, la correlación de Pearson, un modelo de regresión logística y el análisis de las curvas Receiver Operating Characteristic (ROC). Resultados: la proporción de HBPL fue mayor en los hombres (34,68 %; p < 0,01). Hubo una correlación positiva (p < 0.01) entre todas las medidas antropométricas y PAS y PAD. La CC en los hombres (OR: 3,66; p < 0,01) y el IMC en las mujeres (OR: 5,06; p < 0,01) mostraron las mayores asociaciones con los HBPL. No hubo diferencia estadística (p > 0.05) en el área bajo la curva. Conclusiones: los hallazgos de nuestro estudio sugieren que la RFM no es el mejor índice para predecir el HBPL, aunque ha mostrado asociaciones positivas.

            Waist-to-height ratio is a better screening tool than waist circumference and BMI for adult cardiometabolic risk factors: systematic review and meta-analysis.

            Our aim was to differentiate the screening potential of waist-to-height ratio (WHtR) and waist circumference (WC) for adult cardiometabolic risk in people of different nationalities and to compare both with body mass index (BMI). We undertook a systematic review and meta-analysis of studies that used receiver operating characteristics (ROC) curves for assessing the discriminatory power of anthropometric indices in distinguishing adults with hypertension, type-2 diabetes, dyslipidaemia, metabolic syndrome and general cardiovascular outcomes (CVD). Thirty one papers met the inclusion criteria. Using data on all outcomes, averaged within study group, WHtR had significantly greater discriminatory power compared with BMI. Compared with BMI, WC improved discrimination of adverse outcomes by 3% (P < 0.05) and WHtR improved discrimination by 4-5% over BMI (P < 0.01). Most importantly, statistical analysis of the within-study difference in AUC showed WHtR to be significantly better than WC for diabetes, hypertension, CVD and all outcomes (P < 0.005) in men and women. For the first time, robust statistical evidence from studies involving more than 300 000 adults in several ethnic groups, shows the superiority of WHtR over WC and BMI for detecting cardiometabolic risk factors in both sexes. Waist-to-height ratio should therefore be considered as a screening tool. © 2011 The Authors. obesity reviews © 2011 International Association for the Study of Obesity.

              A better index of body adiposity.

              Obesity is a growing problem in the United States and throughout the world. It is a risk factor for many chronic diseases. The BMI has been used to assess body fat for almost 200 years. BMI is known to be of limited accuracy, and is different for males and females with similar %body adiposity. Here, we define an alternative parameter, the body adiposity index (BAI = ((hip circumference)/((height)(1.5))-18)). The BAI can be used to reflect %body fat for adult men and women of differing ethnicities without numerical correction. We used a population study, the "BetaGene" study, to develop the new index of body adiposity. %Body fat, as measured by the dual-energy X-ray absorptiometry (DXA), was used as a "gold standard" for validation. Hip circumference (R = 0.602) and height (R = -0.524) are strongly correlated with %body fat and therefore chosen as principal anthropometric measures on which we base BAI. The BAI measure was validated in the "Triglyceride and Cardiovascular Risk in African-Americans (TARA)" study of African Americans. Correlation between DXA-derived %adiposity and the BAI was R = 0.85 for TARA with a concordance of C_b = 0.95. BAI can be measured without weighing, which may render it useful in settings where measuring accurate body weight is problematic. In summary, we have defined a new parameter, the BAI, which can be calculated from hip circumference and height only. It can be used in the clinical setting even in remote locations with very limited access to reliable scales. The BAI estimates %adiposity directly.
