We studied features of preschool children’s nutrition. It was revealed that the quantitative and qualitative characteristics of the average daily rations do not comply with the established requirements of the current regulations. A hygienic assessment of arsenic content in staple foods during the 2005–2016 period in the Primorsky Territory is given. The results of a study of the effects of arsenic content on the morbidity of the digestive system in children are presented. The dynamics of the primary morbidity indicators by average annual values is shown. A statistically significant relationship has been established between the actual concentrations of arsenic in food products and digestive diseases among the children of the Primorsky Territory.

Introduction: Establishing geographical features of health effects of socio-economic factors and characteristics of adaptation of certain population groups to new living conditions is important for taking appropriate preventive measures to improve the situation and for strategic planning in the sphere of health care and social development of territories. The purpose of the research was to determine priority regional risk factors for pancreatic disorders in the population of Primorsky Krai. Materials and methods: We conducted a hygienic and statistical analysis of the impact of selected socio-economic factors on the incidence rates of pancreatic diseases in children, adolescents, and adults. The database on the registered non-communicable disease incidence included the indices registered by the Primorsky Regional Medical Information and Analytical Center. The study of socio-economic factors included a quantitative assessment of data on three groups of indicators including living conditions, material well-being, and medical density over a 17-year observation period extracted from the regional yearbooks of the Department of the Federal State Statistics Service for Primorsky Krai. Results: We established an inverse relationship between pancreatic disease rates and the indices of population density, per capita income, and solvency ratio and a direct relationship with the proportion of living space in houses without utilities. Conclusion: Our findings enabled us to establish the relationship between adverse effects of socio-economic factors and pancreatic diseases in the regional population and to make a significant contribution to substantiating appropriate measures of primary prevention at the population level.
