ABSTRACT

Aim:

to asses Total Energy Expenditure (TEE) in healthy Chilean institutionalized or independently older people

Methods:

twenty seven young (27-30 years), 27 institutionalized (> 65 years old) and 27 free-living older (> 65 years old) participants were studied. Body composition was estimated by dual energy X-ray absorptiometry. Physical activity energy expenditure (AEE) and TEE were assessed using Actiheart accelerometers. The Mini Nutritional Assessment (MNA) was applied and Timed Up and Go (TUG) was measured.

Results:

AEE was 171, 320 and 497 kcal/day in institutionalized, free living older and young participants, respectively (p< 0.01 between young and older participants). Both absolute TEE and TEE/RMR was higher in young people. Multiple regression analysis accepted age, MNA and TUG as significant predictors of AEE (r2 = 0.24 p< 0.01).

Conclusion:

AEE and PAL were lower among older people, with no differences by institutionalization (AU)
RESUMEN

Objetivo:

evaluar el Gasto Energético Total (GET) en ancianos sanos que viven institucionalizados o independientes en Chile.

Método:

se evaluaron veintisiete jóvenes (27-30 años), 27 adultos mayores institucionalizados (> 65 años) y 27 ancianos independientes (> 65 años). Se midió la composición corporal utilizando absorciometría bifotónica de rayos X. Se calculó el gasto energético por actividad física (GEAF) y el gasto energético total (GET) utilizando acelerómetros Actiheart; se aplicó Mini Nutritional Assessment (MNA) y se midió el Timed Up and Go (TUG).

Resultados:

el GEAF fue 171, 320 y 497 kcal/día en ancianos institucionalizados, independientes y jóvenes, respectivamente (p <0,01 entre jóvenes y ancianos). Tanto el valor absoluto de GET como GET/GER fue más alto entre los jóvenes. El análisis de regresión múltiple aceptó la edad, el MNA y el TUG como predictores significativos de GEA (r2 = 0,24 p < 0,01).

Conclusión:

el GEAF y el nivel de actividad física (PAL) fueron más bajos en los adultos mayores, sin diferencias por institucionalización (AU)
