- Аннотация: Sanogenetic monitoring of schoolchildren’s health has demonstrated that, among high school students, the proportion of adolescents with elevated blood pressure (hypertension + hypernormotension) has risen from 15–20% in 8th-year students to 30–50% in 9th- to 11th-year students, while the proportion of adolescents with hypertension was 3.7% in all age groups. The level of blood pressure (BP) was compared with parameters of the autonomic control of the cardiovascular system. A high normal BP in adolescents 13–14 and 17–18 years of age was correlated with the higher proportion of low frequencies in the spectrum of heart rate variability (HRV) and with the lower sensitivity of the arterial baroreflex. At the age of 15–16 years, a high normal BP was accompanied by a reduced heart rate and a higher sensitivity of the arterial baroreflex; BP correlated also with a decrease in power of the high-frequency region of the HRV spectrum. Unlike normotensive age-matched subjects, hypernormotensive adolescents 15–16 years of age have a lower finger blood pressure and reduced relative power of the low-frequency range in the HRV spectrum during the functional test (an increase in the dead space). This may be a result of a functional inadaptability of sympathetic autonomic regulation.
