Relevance. The section «respiratory morbidity» includes an extensive list of diseases such as bronchitis, pneumonia, bronchial asthma, chronic obstructive pulmonary disease, tonsillitis, influenza, acute respiratory viral infections, and others.

Respiratory organs are the most open system of the human body constantly interacting with the air environment, the quality of which depends on pathological changes in the bronchopulmonary system, leading to an increase in the overall incidence of lung diseases. The most important impact on the respiratory organs have unfavorable factors associated with the pollution of the territory of residence, the presence of harmful substances in the air, drinking water, hereditary predisposition of the person, his lifestyle, the presence of bad habits, the spread of new viruses.

The aim of the study was to identify the dynamics of respiratory diseases among the population living in Russia with the dynamics of this type of diseases in the residents of Primorsky and Khabarovsk Territory.

Materials and methods. The dynamics of respiratory diseases morbidity was analyzed according to the statistical materials of the Ministry of Health of the Russian Federation, Federal State Statistics Service, presented in the annual collections «Health Care in Russia» for 2017-2022 [6].

Analyzing the dynamics of the data of the Ministry of Health of Khabarovsk Krai, which are published on the website of Khabarovskstat and the data of the Ministry of Health of Primorsky Krai, published on the website of Primorskstat for 2017-2022 [3, 7].

The following indicators were included in the study: respiratory morbidity in patients residing in Primorsky Krai; incidence of respiratory disease diagnosed for the first time in life in patients living in Primorsky Krai; respiratory morbidity in patients living in the Khabarovsk Territory; incidence of respiratory disease diagnosed for the first time in life in patients living in Khabarovsk Krai.

Indicators were assessed for the population of Primorsky Krai and for the population of Khabarovsk Krai.

Results of the study. The incidence of respiratory diseases in patients living in the territory of                    Primorsky Krai in the period 2017-2022 is presented in Table 1.

Table 1

Respiratory morbidity in patients living in the territory of Primorsky Krai in the period 2017-2022.

The analysis of dynamics for this period of time showed that the morbidity of respiratory diseases occupies a significant specific weight in the structure of all diseases registered in the territory of Primorsky Krai in the period 2017-2022. It can be noted that the incidence of respiratory diseases is almost half of all diseases, which characterizes them as the most common. As Figure 1 shows, for the analyzed period of time, the incidence of respiratory diseases in the territory of Primorsky Krai for the period 2017-2022 has an upward trend (Fig.1).

            Thus, if in 2017, 635.1 cases of the disease under study were detected, in 2021, this indicator increased to 742.9 units of detected cases, which is probably due to damage to the systems of external respiration against the background of the course of COVID 19, but in 2022 also the incidence remains at a fairly high level (Fig.2).

            Conducting a comparative analysis of data on Khabarovsk Primorsky Krai allowed to reveal unidirectional dynamics. The percentage of respiratory diseases is half of all detected cases of respiratory diseases.

            However, in the studied region, it is somewhat higher than the universal picture and occupies a significant specific weight in the structure of all diseases registered on the territory of Khabarovsk Krai for the period 2017-2022 (Fig.3).

Figure 3 — Specific weight of respiratory diseases in the territory of Khabarovsk            Krai in the structure of all types of diseases for the period 2017-2022, %.

If in 2017 in the structure of all types of diseases, the indicator was equal to 48.27%, in 2022, this indicator increased by 3.79% and amounted to 52.06%, indicating an increase of 7.85%. These data exceed the diseases in Primorsky Krai by 7.38%.

A particularly high period on the territory of Khabarovsk Krai was noted in 2020, during the period of coronovirus infection spread. Afterwards, a slight decline was noted. However, in 2022, the incidence rate increased to 52.06%, and exceeded the figures for Primorsky Krai in this period of time. Let’s consider the dynamics of disease growth in quantitative terms (Fig. 4)

Figure 4 — Dynamics of respiratory diseases in Primorsky Krai and Khabarovsk Krai for the period 2017-2022, %.

Analysis of the data allows to reveal that from 2017 to 2022 in Khabarovsk Krai there is a steady increase in the incidence of respiratory diseases in the population, with a slight decline in 2019 and a sharp jump in growth in 2022 (Fig.5).

Figure 5 — Dynamics of respiratory diseases in Khabarovsk Krai for the period 2017-2022, %

Thus, the study on the territory of Primorsky Krai and in Khabarovsk Krai for 2017-2022 there is a dynamics of growth of respiratory diseases. However, in Khabarovsk Krai, in contrast to the presented statistical data of Primorsky Krai, the dynamics of growth is observed at a higher rate and occupies a greater specific weight in the structure of all diseases.

            Conclusions. The percentage of respiratory diseases is about half of all detected diseases. However, Khabarovsk Krai, has a higher rate of increase in respiratory diseases in the structure of all diseases registered for the period 2017-2022.
