Comparison of anthropometry to DXA: a new prediction equation for men

Objective: This study compared three professionally recommended anthropometric body composition prediction equations for men to dual energy X-ray absorptiometry (DXA), and then developed an updated equation, DXA Criterion (DC) from DXA. Design: Cross-sectional. Setting: Exercise Physiology Lab. University of Missouri-Columbia, USA. Subjects: A total of 160 men aged 18-62 y old. Interventions: Percent body fat (%BF) by anthropometry was compared to DXA on the same day. Results: Although %BF was significantly correlated (r ¼ 0.923-0.942) (Po0.01) with DXA for all three equations, each equation underestimated %BF (range ¼ 3.1-3.3%) (Po0.01) compared to DXA. The following DC equation for men was created: %BF ¼ 0.465 þ 0.180(S7SF)À0.0002406(S7SF) 2 þ 0.06619(age); (S7SF ¼ sum of chest, midaxillary, triceps, subscapular, abdomen, suprailiac, thigh; age ¼ years). The predicted residual sum of squares (PRESS) R 2 was high (0.90) and the PRESS standard error of estimates was excellent (2.2% at the mean) for the DC equation when applied to our sample of 160 men. Conclusions: The currently recommended anthropometric equations for men underestimate %BF compared to DXA. The DC equation yields a more accurate estimation of %BF in men aged 18-62 y old. The results from this study support the need for the current %BF standards and norms for men to be adjusted upward.

Introducción. La antropometría y el análisis de la impedancia bioeléctrica o bioimpedancia son métodos de campo ampliamente utilizados en nuestro medio para la evaluación de la composición corporal; a pesar de ello, se desconoce si generan resultados comparables. Objetivo. Comparar la composición corporal de adultos sanos evaluados por antropometría y bioimpedancia. Materiales y métodos. Se evaluaron 70 mujeres (entre los 22 y 56 años) y 53 hombres (entre los 24 y 54 años) por el método antropométrico: ecuaciones de Durning/Womersley y Jackson/ Pollock, y por bioimpedancia: técnica pie-pie. La medición de los pliegues cutáneos se hizo con un calibrador Lange y la bioimpedancia se efectuó con una báscula Tanita TBF300. Para la comparación de los métodos se empleó la t de Student pareada, la correlación de Pearson, la diferencia de proporciones y el índice kappa. Resultados. El porcentaje de grasa promedio en los hombres fue mayor (p=0,000) por Durning/ Womersley (25,2%) que por Jackson/Pollock (20,1%) y bioimpedancia (19,3%). En las mujeres, el porcentaje de grasa promedio fue mayor (p=0,000) por Durning/Womersley (36,9%) que por Jackson/Pollock (31,0%) y bioimpedancia (27,6%). Hubo una alta correlación entre los métodos (r>0,77) pero, al aplicar el mismo punto de corte para definir la obesidad, se encontró una baja concordancia entre estos (K<0,5). Conclusión. El método antropométrico, ecuación de Durning/Womersley, estimó los porcentajes de grasa más altos y la bioimpedancia, los más bajos. Se encontraron diferencias significativas entre los métodos y entre las ecuaciones antropométricas, lo cual sugiere que sus resultados no son comparables ni intercambiables.Palabras clave: composición corporal, índice de masa corporal, antropometría/métodos, impedancia eléctrica, adulto. Body composition assessment by anthropometry and bioelectrical impedanceIntroduction. Anthropometry and electric impedance methods are widely used for body composition assessment. However the evidence is unclear whether the results obtained from the two methods can be compared. Objective. Two methods are compared for assessment of body composition; anthropometry and electric impedance. Materials and methods. Body composition was measured in 70 women; aged 22 to 56 and 53 men; aged 24 to 54, using anthropometry (Durning/Womersley and Jackson/Pollock skinfolds equations) and electric impedance (foot to foot electric impedance) to obtain percentage body fat. Results. The mean percentage body fat was significant higher with Durning/Womersley (25.2%) than Jackson/Pollock (20.1%) and electric impedance (19.3%) for men (p<0.001). The mean percentage body fat was significant higher with Durning/Womersley (36.9%) than Jackson/Pollock (31.0%) and electric impedance (27.6%) for women (p<0.001). Correlation coefficient was high when two methods were compared (r>0.77) however, the concordance between methods to classify obesity subjects was low (K<0.5).
