Development and validation of age-specific predictive equations for total energy expenditure and physical activity levels for older adults.

ABSTRACT:

Background

Predicting energy requirements for older adults is compromised by the underpinning data being extrapolated from younger adults.

Objectives

To generate and validate new total energy expenditure (TEE) predictive equations specifically for older adults using readily available measures (age, weight, height) and to generate and test new physical activity level (PAL) values derived from 1) reference method of indirect calorimetry and 2) predictive equations in adults aged ≥65 y.

Methods

TEE derived from "gold standard" methods from n = 1657 (n = 1019 females, age range 65-90 y), was used to generate PAL values. PAL ranged 1.28-2.05 for males and 1.26-2.06 for females. Physical activity (PA) coefficients were also estimated and categorized (inactive to very active
