ABSTRACT
Analysis of prevalence of various functional disorders and chronic diseases diagnosed in children and adolescents during comprehensive prophylactic examination in educational institutions does not provide complete information about health tendencies because the same statistical data may reflect both favourable development of a pathological process and its deterioration. Such information can be obtained by thorough analysis of complaints, medical histories and catamnestic observations, fulfillment of the complete range of regimented clinical examinations. An algorithm and criteria for characterization of a pathological process as "improving", "worsening" or "unaltered" were developed for different nosological forms and classes of diseases in 2006. It was shown that stage by stage differential assessment of pathological processes and functional disorders in junior and senior schoolchildren in different periods of their development during school years yields new data on different phases of adaptation, occurrence of its favourable and unfavourable outcomes; also, it permits to identify schoolchildren in need of urgent curative and preventive aid.
