PAKOZDI, Tamara et al. Factors related to total energy expenditure in older adults (Chile). Nutr. Hosp. [online]. 2015, vol.32, n.4, pp.1659-1663. ISSN 1699-5198.  https://dx.doi.org/10.3305/nh.2015.32.4.9189.

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.
