Assessment of the Functional State of the Cardiovascular System in Adolescents Living in the Southern Aral Sea Region

Abstract

According to studies conducted in recent years, there is a harmful effect of harmful chemicals in the environment on the cardiovascular system. The level of blood pressure is a very important hemodynamic indicator, the level of which provides primary information about diseases of the cardiovascular system. In this study, the indicators of total body size, blood pressure and heart rate were measured in adolescents living in unfavorable environmental conditions of the Aral Sea region. In adolescents of both sexes, body weight deficiency occupied a significant share. In girls and boys, the excess body weight was about 5%. Obesity was not observed in adolescents of both sexes. Hypotension was detected in 17.64% of the females studied by categories of systolic blood pressure, and there were no cases of hypertension among the females. And in males, hypotension of 8.70% and hypertension of 4.35% were observed. According to the categories of diastolic blood pressure, hypotension of 2.95% and hypertension of 8.82% were detected in females, hypotension of 8.69% and hypertension of 8.70% in males.

Features of Morphofunctional Indicators of Adolescents in the Environmental Conditions of Karakalpakstan

“…However, in 15-yearold boys, hypotension was observed in 8.70% and hypertension in 4.35%. And according to the categories of diastolic blood pressure, 2.95% of cases of hypotension and 8.82% of cases of hypertension were detected in girls, 8.69% of cases of hypotension and 8.70% of cases of hypertension in boys [22]. living in the Republic of Karakalpakstan have higher systolic blood pressure than girls of the same age.…”

“…Secondly, chronic effects also cause cardiovascular diseases and lead to an increase in the mortality rate from all causes compared to acute effects [15]. According to recent studies [22], hypotension by systolic blood pressure categories was not detected in 17.64% of 15-year-old girls living in the city of Nukus of the Republic of Karakalpakstan, and there were no cases of hypertension among girls. However, in 15-yearold boys, hypotension was observed in 8.70% and hypertension in 4.35%.…”

“…One of the regions with such unfavorable environmental conditions is undoubtedly the Aral Sea region. A number of negative environmental factors (dust and salt storms, pesticides, heavy metals, salinity, poor quality of drinking water) caused by the drying of the Aral Sea also had a negative impact on the health of the population living in this region [7, 16,22,26,28]. In particular, this has led to the morphofunctional development of children [19,23], adolescents [20], young men [26,28], girls [24,26,28], athletes [13,27], an increase in the incidence among the population of diseases related to the respiratory system [7, 16], digestive system [7], endocrine system [7], cardiovascular system [7,8,21,22,23], oncology [7, 18], reproductive system [7,25].…”
