[Predicting the dynamics of elevated arterial pressure in 12--13-year-old children of Kaunas and Berlin].

The increased arterial blood pressure (BP) variation between 12-13 and 15-16 years of age was examined in 119 schoolchildren of Kaunas and 169 schoolchildren of Berlin. The 90th percentile for systolic and/or diastolic BP was used as a criterion of increased arterial BP. The data were treated by multivariate logistical regression analysis. Independent samples were used to construct and test the model. The reproducibility of increased arterial BP was shown to be affected by physical developmental status as well as baseline systolic and diastolic BP, the influence being more pronounced in girls, as compared to boys. The derived formulas are presented as a nomogram to facilitate their practical application.
