The method of predicting the development of chronic bronchitis of children and adolescents includes determination of risk factors, including smoking, and analysis for clinical and functional parameters of each indicator providing appropriate score and calculating the amount of points. Determination of the following clinical and functional parameters and analyzed, giving each indicator points respectively in their presence and influence on the patient and on the basic pathogenesis of chronic inflammation: disease experience (recurrent bronchitis) over 5 years - 5, heredity for chronic bronchopulmonary diseases - 4 points, long oxygen therapy in the neonatal period - 2 points, more than 3 bronchitis per year - 2 points, pneumonia with prolonged course or severe acute respiratory disease at an early age - 13 points, smoking - 9 points, muscular hypotonia - 6 points, deformity of the chest or scoliosis - 1 point, the presence of dyspnea - 10 points, reduced mobility of walls of the trachea and bronchi by visual examination during bronchoscopy - 4 points, bilateral endobronchitis - 3 points, purulent endobronchitis - 2 points, irreversible decrease in FEV1 <；80% of normal - 4 points, the level of alpha-1 antitrypsin blood <；0,8g / 1-10 points, serum transforming growth factor TGF-( in blood - 2 points, reducing the potential proliferation of bronchial epithelium according to immune-histamine analysis - 12 points, level of SDG in lymphocytes - 1 point, and at a point total of 60 or higher followed by predicting risk of developing chronic bronchitis.Способ прогнозирования развития хронического бронхита у детей и подростков включает определение факторов риска, в частности наличие курения, и их анализ по клинико-функциональным показателям с предоставлением каждому показателю соответствующего балла и вычислением суммы всех баллов. Определяют у больного следующие клинико-функциональные показатели и анализ, предоставляя каждому показателю баллы соответственно его наличию у
