Ambulatory twenty four hour blood pressure monitoring (ABPM) is an exact method, enabling by repeated measurements to create blood pressure profile, which shows a close correlation with end organ damage. Normal values were taken from clinical trials, where the mean age of probands was highly above 30 years. The aim of this trial was to determine mean values for ABPM in population aged 18-30 years and to create "normal values" for this population. We have examined 162 probands. The mean office blood pressure was 128.18 +/- 11.2/82.91 +/- 8.29 mm Hg, the mean ABPM (24 hours) was 118.51 +/- 9.11/70.59 +/- 6.30 mm Hg. Systolic, mean and pulse pressure was significantly higher in males. Systolic and pulse blood pressure showed a close correlation with height, weight, waist and waist/hip ratio (r = 0.40-0.47). The upper value of 24 hour BP in young population is between 125/75 mm Hg and 130/80 mm Hg according to our results.
