DEXA e Bioimpedância: comparação avaliativa em pacientes obesos na cidade de Cáceres, MT - Brasil

Abstract

Obesity is a health problem known to increase the morbidity and mortality of individuals. Although widely used, BMI is not considered a good parameter to assess harmful levels of body fat, as it is not a good predictor of mortality. Several assessment methods have been proposed as a substitute for BMI over the years, with emphasis on the waist-to-hip ratio. Despite several articles evaluating it in a positive way, the predictive capacity of this method is still inconclusive. This study evaluates data on body components and correlates with central obesity and percentage of abdominal fat collected by BIA and DEXA equipment in a population in Cáceres - MT. The evaluated devices had similar performance, with statistical difference only between the measurements of the waist-hip ratio (p = 0.026). A non-parametric analysis of the data collected shows that waist circumference may be related to an increased risk of hypertension.
