[Systematic model of the sanologic status of children and adolescents]

The paper presents the results of information and systemic analysis as the methodological basis for study of the gestation age phenomenon as a sociohygienic problem. The proposed information-systemic model permits description (by means of current systemic entropy) of the time course of health in the cohort of children and adolescents from birth to 18 years. The model demonstrates differences in the health status, depending on the gestation age, and explains the causes of these differences.
