Dynamics of bronchial asthma morbidity in Crimea

Aim. To assess the dynamics and age-specific patterns of bronchial asthma (BA) morbidity in the Republic of Crimea from 2017 to 2024.
Materials and methods. Data from the official statistical reporting form No. 12 ("Information on the Number of Diseases Registered Among Patients Residing in the Service Area of a Medical Organization") for the years 2017–2024 were analyzed. Regression analysis was used to quantitatively evaluate trends in BA morbidity.
Results. Overall BA morbidity increased from 796,570/0000 in 2017 to 936,16 0/0000 in 2024. Primary incidence rose from 37,430/0000 to 53,780/0000 over the same period. Age-specific trends varied: in the post-pandemic period, both overall and primary incidence declined among children and adolescents (0–14 and 15–17 years), whereas a clear increase was observed in adults aged 18–59 and those aged 60+. Regression analysis confirmed a statistically significant annual increase in BA incidence during the study period (β = 355.3 cases per year; p < 0.001).
Conclusion. Crimea has demonstrated a consistent upward trend in both overall and primary BA morbidity. Pre-pandemic years showed rising rates across all age groups. During the pandemic, primary incidence continued to increase while overall morbidity remained stable. In the post-pandemic period, incidence rose among adults (>18 years) but declined in those under 18 years of age.
