  • Research summary

    Dual-energy x-ray absorptiometry (DXA) has several applications including the measurement of bone mineral density for the identification of osteoporosis (a condition that affects the strength of bones) and body composition (how much fat and muscle tissue you have). It may also be used to estimate resting energy expenditure (how much energy your body is using at rest). As the iDXA is estimating energy expenditure, the best prediction models to use are unclear hence, we have adapted a model from various other models in the literature to see how accurately it estimates resting energy expenditure compared with indirect calorimetry. Indirect calorimetry is a well-established, very sensitive and accurate way of measuring energy expenditure in humans. Therefore, this study aims to observe how well predictions of energy expenditure taken from the iDXA calculations compare with those from indirect calorimetry.
