Abstract

Amaç: Bireylerin antropometrik ölçümlerini ve vücut bileşimlerini belirlemek, toplam vücut suyunun tahmininde kullanılan formüllerden elde edilen vücut suyu değerinden diğer vücut bileşenlerini hesaplayıp bu değerlerin biyoelektrik impedans analizi (BİA) sonuçlarıyla uyumluluğunu değerlendirmek ve cinsiyete özgü yeni denklemler geliştirmektir.
Yöntem: Araştırma, 18-50 yaş arası 103 birey (67 kadın, 36 erkek) ile yürütülmüştür. Bireylerin antropometrik ölçümleri (vücut ağırlığı, boy uzunluğu) alınmış ve dual frekans BİA cihazı ile vücut bileşimleri (toplam vücut suyu, vücut yağ yüzdesi ve yağsız vücut kütlesi) analiz edilmiştir. Bireylerin antropometrik ölçümleri kullanılarak Watson, Hume, Chertow, Deurenberg formülleri ile vücut suyu ve buna bağlı olarak diğer vücut bileşimleri hesaplanmıştır. Her bir formül için bulunan değer BİA cihazı ile bulunan değerle gösterdiği korelasyon ve uyum açısından değerlendirilmiştir. Regresyon analizi ile vücut bileşiminin tahmini için cinsiyete özgü yeni denklemler geliştirilmiştir.
Bulgular: Tek yönlü varyans analizi sonucunda farklı ölçüm yöntemleri ile elde edilen toplam vücut suyu, yağsız vücut kütlesi ve vücut yağ yüzdesi aritmetik ortalamaları arasındaki fark istatistiksel olarak anlamlı bulunmuştur (p<0.05). Tukey testi sonucunda BİA ve Chertow denklemi ile hesaplanan toplam vücut suyu ortalamaları arasında istatistiksel olarak anlamlı bir fark olduğu bulunmuştur (p<0.05). Bland-Altman analizi ise toplam vücut suyunun tahmini açısından biyoelektrik impedans analizi ile Hume denklemi arasında yüksek bir uyum olduğunu göstermiştir.
Sonuç: BİA cihazına erişimin olmadığı ya da çeşitli sebeplerle uygulanamadığı durumlarda vücut bileşiminin tahmini açısından Watson, Hume ve Deurenberg denklemlerinin kullanımı oldukça yararlıdır.

Compatibility of Body Composition Estimated by Anthropometry-Based Equations with Bioelectric Impedance Analysis Results

Abstract

Purpose: The aim of this study is to determine the anthropometric measurements and body composition of individuals, calculating other body components from the body water value obtained from the formulas used in the estimation of total body water and evaluating the compatibility of these values with the bioelectrical impedance analysis (BIA) results, and to develop new gender-spesific equations.
Methods: The research was carried out with 103 individuals (67 females, 36 males) between the ages of 18-50. Anthropometric measurements (body weight, height) of the individuals were taken and their body compositions (total body water, body fat percentage and lean body mass) were analyzed with a dual frequency BIA device. Body water was calculated with Watson, Hume, Chertow, Deurenberg formulas using anthropometric measurements of individuals and then other body compositions were calculated. The value found for each formula was evaluated in terms of correlation and compatibility with the value found with the BIA device. New gender-spesific equations have been developed for the estimation of body composition by regression analysis.
Results: As a result of one-way analysis of variance, the difference between the arithmetic averages of total body water, lean body mass and body fat percentage obtained with different measurement methods was found to be statistically significant (p<0.05). As a result of the Tukey test, it was found that there was a statistically significant difference between the mean total body water calculated by the BIA and the Chertow equation (p<0.05). Bland-Altman analysis showed a high agreement between bioelectrical impedance analysis and Hume's equation for the estimation of total body water.
Conclusion: In cases where the BIA device is not accessible or cannot be applied for various reasons, the use of Watson, Hume and Deurenberg equations is very useful in terms of estimating body composition.
