Regional Features of the Functional State of the External Respiratory System Among Adolescents From Different Regions of Uzbekistan

This study examines the functional state of the external respiratory system in adolescents living in the Republic of Karakalpakstan, Bukhara region, and Tashkent region. The study involved 126 adolescents aged 15–17 years. Lung vital capacity, respiratory rate, breath-holding indices, and selected cardiovascular functional parameters were assessed. A comparative analysis was conducted among participants living under different climatic and environmental conditions. The obtained data demonstrated that environmental conditions, air quality, and ecological characteristics of the region significantly influence respiratory system parameters. Adolescents living in relatively favorable ecological areas showed higher lung vital capacity, better breath-holding performance, and improved functional reserves.
