title: [Investigation of osteoporotic changes of the long tubular leg bones for identification of human biological age].
abstract: The authors propose to introduce into expert practice a number of methods estimating age-related osteoporosis by such quantitative characteristics as coefficient of optical transmission, optic density, porosity. The data confirm nonlinear dependence of age dynamics of osteoporotic changes which can be more effectively described by equations of polynomial regression.
