Biological age
Abstract
Biological age determines the degree of biological maturity of a child’s organism. It characterises the complex state of an individual’s growth and development, and it represents an index that helps to define its morphological and functional traits. Biological age can be regarded generally as a process of physiological, biochemical, mental and anatomical ageing. It determines the state of a child’s development in respect to a definite age standard and classifies its position in the so-called ‘zones of growth velocity’ (acceleration, average development, retardation).
