[Tables of the arterial hypertension in children in Italy (from 0 to 18 years)].

For the first time in Italy, the results of a multicentre study of the Study Group into Juvenile Hypertension of the Italian Society of Paediatrics in 16.772 subjects from 0 to 18 years, are presented. Percentile charts (tables) of juvenile blood pressure (BP) levels according respectively to age and height of the subjects divided by sex, have been elaborated. Also pressure curves have been calculated and drawn that are based on standard deviations (DS). Normal levels are between + and -2DS. The relationship of BP levels with age permits the comparison with the Task force Tables, whilst the relationship with height permits comparison with the European data.
