Valuation methods and anthropometric bioimpedance: a correlational study in industrial workers

Abstract

Background and Objectives: The assessment of nutritional status by anthropometry and bioelectrical impedance analysis (Bia), emerges as a promising tool more affordable. This study examined the correlation between two body evaluation methods (anthropometric and body composition and visceral fat area by Bia) in industrial workers. Methods: This is a crosssectional, descriptive and correlational character, with 22 industrial workers, the city of Santa Cruz do Sul-RS. For the assessment of body composition were measured anthropometric variables: body mass index (BMI), waist circumference (WC), Risk Waist Hip ratio (WHR), body fat percentage (BF%), fat weight (PG); lean body mass (LBM); bone weight (PO). For body composition used to Bia through the octopolar multi-frequency analyzer (In-Body 720) for the variables: mineral content (CM); fat mass (MG); musculoskeletal mass (MME); BMI; % G; WHR and visceral fat area (VFA). In the statistical analysis we used the Pearson correlation test to evaluate the correlation between the variables. Results: Of the 22 workers, 72.7% were female, mean age of 37.73 years. They had an average BMI of 26,14kg / m², which classifies the sample overweight. In the study, the assessments made by the two techniques showed a strong correlation between BMI and IMCBia variables% F and% GBia, PG and MGBia, MCM and MMEBia, PO and CMBia, DC and AGVBia. Conclusion: Both methods showed obtain similar statistical behavior in body evaluation, suggesting the possibility of using any of these techniques to assess body composition.
