[Clinical characteristics of juvenile systemic hypertension in the population of Tbilisi].

The goal of the work was to study a prevalence of juvenile systemic hypertension among 15-16 years old adolescents of Tbilisi, its clinical characteristics and several indices of mental capacity. In the result of an analysis of 378 adolescents' blood pressure records only 6 (1.6%) had high normal values and 32 (8,46%) revealed juvenile systemic hypertension. Four youths from 6 with high normal values refused to participate in a further investigation. For this reason the study was continued only in 32 youths with juvenile systemic hypertension. In the contingent noted 6 (18,75%) had overweight, 9 (28,12%) had hereditary predisposition, 15 (46,9%) revealed excessive use of salt, 3 (9,4%) had moderate consumption of alcohol and 7 (21,9%) noted insufficient physical activity. Juvenile systemic hypertension in youth was predominantly asymptomatic, only 9 (28,12%) had mild headache in the evening, 12 (37,5%) had light fatigue and 5 (15,6%) weak dizziness. Fourteen youths noted diminished work-status and being behind in learning process. In the persons with juvenile systemic hypertension diminution of the attention concentration was observed during a fulfilment of a simple sensor and motor task in condition of monotonous work (increment of answers missed up to 13+/-12%). A psycho-emotional loading test has proved the fact of mental capacity lowering within the persons with juvenile systemic hypertension that is expressed in the increment of errors made up to 12+/-3,1% and answers missed up to 11+/-2,3%. Our investigations confirm the reasonability of blood pressure monitoring among adolescents for the early detection of the juvenile systemic hypertension and the conduction of an opportune preventive measures for avoiding of cardiovascular diseases in a mature age.
