Estudio comparativo del cálculo del gasto energético total mediante Sense Wear Armband y la ecuación de Harris-Benedict en población sana ambulatoria: utilidad en la práctica clínica Comparative study of total energy expenditure estimated by Sense Wear Armband and Harris-Benedict equation in healthy ambulatory population: utility in clincal practice

Abstract

Introducción: Existen diferentes metodologías para la estimación del Gasto Energético Total (GET). Objetivo: Conocer qué herramienta resulta más útil para la estimación del GET en sujetos sanos: SenseWearArmband (SWA) o Harris-Benedict (HB). Metodología: Estudio transversal realizado en 32 voluntarios. Se colocó el SWA durante 24 h y se estimó el GET con HB y el factor de actividad calculado con un cuestionario de actividad de 24 h. Resultados: La diferencia entre ambas estimaciones en el GET fue de 351,9 (IC 95% 222,2 a 481,6) kcal/día (p Introduction: Different methodologies for estimating total energy expenditure (TEE) are currently used. Objective: To know which tool is most useful to estimate TEE in healthy subjects: SenseWearArmband (SWA) or Harris-Benedict (HB). Methodology: Cross-sectional study in 32 volunteers. SWA was placed for 24 hours and TEE was estimated with HB and the activity factor calculated with a 24-h activity questionnaire. Results: The difference between both estimates of TEE was 351.9 (95% CI 222.2 to 481.6) kcal/day (p < 0.001). This difference was associated with obesity, but not with sex. The value of ICC was 65.0% (95% CI 7.8% to 86.2%) being statistically significant (p < 0.001). There was a significant difference in the estimation of the activity between both techniques [0.4 (CI 95% 0.1 to 0.7) hours (p = 0.007)]. Conclusions: A significant difference in the estimation of TEE using HB and SWA has been found.
