IntroductionHypertension is a major factor related to morbidity and mortality in middle- and high‑income countries.ObjectivesThe aim of the study was to assess the incidence and prevalence of registered hypertension in Poland in the years 2018-2022.Patients And MethodsWe used the public payer claims database to assess incidence and prevalence of registered hypertension. Definition of hypertension was based on the International Classification of Diseases, 10th Revision codes from I10 to I15.ResultsThe number of registered hypertension cases during the analyzed period varied from 10.9 to 11 million. The prevalence was 0.5%, 0.5%, 0.5%, 0.4%, and 0.4% (P <0.001) in children (age <18 years) and 34.4%, 34.8%, 34.9%, 35.2%, and 35.2% (P <0.001) among adults in 2018, 2019, 2020, 2021, and 2022, respectively. In 2022, the mean (SD) age of persons with registered hypertension was 66.2 (14.1) years in women and 60.8 (14.8) years in men (P <0.001). The highest incidence of registered hypertension was found in men aged 55-59 years and in women aged 50-54 years. In the population aged up to 54 years, the registered prevalence of hypertension was higher among men, while in older age groups it was higher in women, reaching 94% and 87% in the oldest groups of women and men, respectively.ConclusionsIn 2022, the number of patients with registered hypertension in Poland was close to 11 million, while the prevalence was 35.2% in adults and 0.4% in children. In the population under the age of 55 years, hypertension is more common in men, while women predominate in the older age groups.
