title: Body composition and the aged: what needs to be measured?
abstract: Within the gerontological and geriatric population studies in Gothenburg, Sweden, body composition studies have been performed with a four-compartment model (using whole-body potassium 40 counting and dilution of isotope labelled water) for two decades, the impedance method for some years and total body nitrogen determination by in vivo neutron activation technique for the last few years. Examples are given from a longitudinal study in 70-year-olds followed at the ages of 75, 79 and 81 years, and from a recent study of 75year-olds.
