[Frequency of selected chronic noncommunicable diseases in older patients with senile asthenia syndrome.]

An important area of medical and social research is prospective studies of a cohort of older patients with chronic non-communicable diseases aimed at studying the level of mortality, taking into account the presence/absence of senile asthenia syndrome. A prospective clinical and epidemiological study was conducted on 1 261 people aged 80 years and older receiving medical care on an outpatient basis. Three groups of patients were formed: without senile asthenia syndrome (7,6%), in a state of pre-asthenia (23,5%), with senile asthenia (68,9%). After a calendar year, an analysis was made of the causes of death of respondents in all three groups. A high statistically significant incidence of chronic diseases in patients with senile asthenia syndrome compared with those without signs of this syndrome was noted in arterial hypertension, chronic heart failure, osteoarthritis, age-related macular degeneration, chronic kidney disease, dementia, cancer, anemia, uncomplicated diabetes mellitus. In the structure of causes of death in patients aged 80 years and older, diseases of the circulatory system, nervous system, neoplasms, liver diseases, and diabetes mellitus predominated. The odds ratio of the risk of dying within a year in patients without frailty syndrome is 0,32 (compared to patients with frailty, in which the risk is taken as 1).
