Incidence of non-tumor diseases of digestive organs in persons aged of 18 years and older evacuated from 30 kilometer exclusion zone in post-accident period (1992–2016)

Abstract

Objective: We carried out the epidemiological analysis of the incidence of non-tumor diseases of digestive organs in the people evacuated from the 30-kilometer zone of the Chornobyl NPP at the age of 18 years and older during the post-accident observation period. Materials and methods: In the post-accident period during1992 - 2016, we performed an epidemiologic study of the incidence of non-tumor diseases of the digestive system in 7,143 people (2,198 men and 4,945 women) aged 18 years and older evacuated from the 30-kilometer zone of the Chornobyl NPP. To assess the digestive disease incidence in the examined people, we studied a structure of the diseases according to the international statistical classification of the diseases of the tenth revision (ICD-10) by the information base of the clinical and epidemiological register of the NACRM NAMSU. Results: As a result of the study of the structure of digestive system diseases, it was found that 91.05% belonged to somatic pathology by the Digestive Diseases’ class. The health of the examined by this class persons deteriorated mainly due to the the development of the diseases of oral cavity, salivary glands and jaws, which made up the largest component (47.17%) and the diseases of esophagus, stomach, and duodenum (34.39%). But a significant loss of health was caused bythe diseases of the gall bladder, biliary tract and pancreas, chronic hepatitis and cirrhosis(8.13%), non-infectious enteritis and colitis, and other diseases of the intestine (1.36%). Only digestive pathology made up8.9% among different classes of ICD-10: "Some infectious and parasitic diseases (A00-B99)", "Tumors (C00-D48)", "Congenital abnormalities (malformations), deformities and chromosomal abnormalities (Q00-Q99)". Irrespective of gender, the morbidity structure of males and females is characterized by the identity of the diseases and the ratio of indicators in the structure of the overall cohort. But females suffered more from gall bladder disease, biliary tract and pancreas disease, oral cavity disease, the malesfrom esophageal, stomach, and 12 duodenal diseases. Conclusions: Determination of the structure of the diseases on the example of diseases of the digestive organsamong the people aged of 18 years and older, evacuated from the 30-kilometer zone of the Chornobyl NPP, enables the identification of priority nosological forms for further illustration of the determined relationship of the effect of ionizing radiation on the health status of the suffered for preventive measures.
