[Median age of patients in the projection of the epidemiological indicator.].

At the population level, accelerated aging can manifest itself as an early manifestation of age-associated pathology. Earlier, as an indicator of the order of manifestation of various diseases, we substantiated the age-specific incidence index (ASII), which is the ratio of the primary incidence rate among people over working age to the same indicator for the entire adult population. At the same time, it seems necessary to explain the mathematical relationship between median age and ASII.

[Fibrophysematous lung changes and microbiota changes in senile persons.].

Research on the condition of the lungs in senile people is an urgent task. This is due to the fact that degenerative or age-associated changes in the respiratory system play an important role in the formation of senile asthenia syndrome and a decrease in the age-related viability of the body as a whole. CT-scans of patients aged 80-90 years were analyzed (n=31).

[The medical significance of loneliness and social isolation in old age (literature review).].

Communication is considered as one of the basic human needs. For a long time, loneliness and social isolation were mainly considered as a psychosocial problem. However, in the recent years, there has been increasing evidence of the possible impact of loneliness and social isolation on the development and clinical course of somatic diseases.

[Analysis of age-related incidence (by circulation) of age-associated pathology in 2018-2023 on the example of the municipal polyclinic of Saint-Petersburg.].

From the age of 25-30, the likelihood of developing pathological processes associated with aging begins to increase. Age-associated diseases (AAD) are a heterogeneous group of pathologies that are more likely to develop as they age. Clinically, the early development of AAD is identical to premature aging with all the ensuing consequences.

[Economic index - predictor of premature aging.].

It is widely known that in economically developed countries there is an increase in the proportion of older people. However, the problem of the influence of territorial features of economic development on the rate of population aging is not sufficiently covered. The goal was to study the impact of economic development indicators (EDI) on the processes of premature aging of the population.
