elderly patients
capacity & vitality

According to Guo et al (1) "understanding the scope of the age-related changes in body composition and the factors associated with them in healthy adults will help to improve our knowledge and understanding of these processes and assist in the prevention of functional limitations and in the management of health status into old age."

A condition often found in the elderly is protein-energy malnutrition (2). Early detection combined with nutritional support can prevent or significantly improve chronic conditions associated with age-related malnutrition. A key element of nutritional assessment is the monitoring of body composition. Bioimpedance analysis (BIA) has been found to be a useful method for estimating body composition in the elderly (3,4,5).
