Objective. A key role in assessing the health of the population belongs to disability, given its high prevalence and the variety of socially significant consequences. Research in Ukraine and around the world shows the global prevalence of diseases of the circulatory system (HSC) among the population. The most adverse effects of the Chornobyl disaster on health and social well-being include the disability of the affected population.
The aim of the study. To analyze the dynamics of disability indicators in the adult evacuated population due to the leading HSC with an emphasis on the peculiarities of their distribution by groups initially recognized as disabled.
Materials and methods. A retrospective analysis of the state of primary disability due to HSC among the adult evacuated population according to the State Register of Ukraine of persons affected by the Chornobyl disaster. Disability analysis was performed according to the data of initially recognized disabled people among the adult evacuated population depending on the time and age at the date of the accident, classes, forms of pathology and groups of persons recognized as disabled. The observation period included 1988–2016. The processing of the obtained data required the formation of a computer database based on Microsoft Excel.
Results. According to the analysis, the HSC continues, as in previous post-accident years, to occupy the first place in the structure of the causes of primary disability in the adult evacuated population. Since the accident, the level of disability has increased compared to the early period and reached the highest levels in the late period (2008-2016), regardless of age. In the most remote years since the accident, a significant jump in the level of disability was found in the younger age group of 18-39 years. In the structure of disability in people aged 18-39 in the late period, the first rank is cerebrovascular pathology (CVD), in second place - coronary heart disease (CHD), in third place - hypertension (GC), in people aged 40-60 the first the place belongs to coronary heart disease, the second - GC, the third place - TsVH. In the HSC class, the representatives of both age categories have the second group of disabilities. The results of the research allowed to determine the features and leading HSCs by primary groups of disability. The presence of persons with group III disability implies a high rehabilitation potential and a positive prognosis for their rehabilitation.
