The relevance of the study of primary arterial hypotension (PAH) in adolescents is due to the high prevalence of this condition and its significant impact on quality of life, cognitive functions, and academic performance. The purpose of this study was to study the prevalence and risk factors of PAH among high school students in Vladikavkaz, as well as to evaluate the effectiveness of a complex of non-drug interventions. 420 students from grades 9-11 participated in the study. The research methods included questionnaires, blood pressure measurements, assessment of cognitive functions using psychometric tests, and analysis of academic performance. The results indicated that the prevalence of PAH among high school students was 30.5%. Significant differences in lifestyle were found: adolescents with PAH slept an average of 6.8 hours a day (versus 7.9 hours in the control group), spent 5.4 hours a day on gadgets (versus 3.9 hours), and in 58.6% of cases regularly skipped breakfast (versus 32.2%). Students with PAH showed a decrease in attention productivity by 22.3%, memory capacity by 18.1%, and attention switching speed by 28.5%. After a three-month course of non-drug correction, which included normalization of daily routine, physical activity, and optimization of gadget usage time, the intervention group (n=64) showed a significant improvement in indicators: an increase in systolic blood pressure from 95.6 to 105.3 mm Hg and diastolic blood pressure from 56.3 to 62.7 mm Hg, a decrease in the frequency of fatigue complaints increased from 93.8% to 40.6%, and improved cognitive performance.
