Concurrent and comorbid diseases among liquidators consequences of the accident at the Chernobyl Nuclear Power Plant with cerebrovascular disorders in long after the accident

The purpose of the study is to explore the prevalence of concurrent and/or comorbid diseases among liquidators consequences of the accident at the Chernobyl NPP with cerebrovascular disorders occurring long after their exposure to radiation, as well as assess the influence of these diseases on the progression of their primary condition. We studied the morbidity of dyscirculatory encephalopathy (DEP), neurocirculatory asthenia (NCA), hypertension (HTN) and coronary artery disease (CAD) among the liquidators (417 people) according to data provided by the Russian Interdepartmental Expert Council on Establishing Causal Relationship of Diseases, Disability and Death of Citizens Exposed to Radiation Factors of the Russian Scientific Center of Roentgenoradiology. The sample was grouped by years of participation in emergency repairs (ER) within the 30-km Chernobyl accident zone (1986-1988) and age of the liquidators when they were first diagnosed with DEP. The difference between the groups was examined using relative risk and 95% confidence intervals. In order to study the cause-and-effect relationships between variables, we used correlation and regression analysis (simple and multiple regression models). Out of DEP stages, the 2nd stage (stage II) was characterized by the highest morbidity rate (p function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
