[On the polypathias in males]
Abstract:
The structure and prevalence of polypatias (i.e. three and more diseases in single person), their qualitative and quantitative characteristics were investigated on the basis of comprehensive population study of 1050 males aged from 18 and older in unorganized rural population. It is established that in the structure of chronic infectious diseases the share of persons with multinozoology constituted 65.3%? with binozoology--18% and with mononozoology--16.7%. The prevalence level of multinozoology among males constituted 604.7 per thousand? binozoology--166.8 per thousand and mononozoology--154.4 per thousand. The leading positions among multinozoologies are taken by the circulatory system diseases (428.0 per thousand), respiratory system diseases (400.4 per thousand) and digestive system diseases (368.9 per thousand). This fact proves the leading role of the diseases of those classes in the development of polypatias.
Insights
Polypathias, defined as three or more diseases in one person, are prevalent in rural males. Circulatory, respiratory, and digestive diseases significantly contribute to the development of multiple chronic conditions.
Area of Science:
- Epidemiology
- Public Health
- Internal Medicine
Background:
- Polypathias, the co-occurrence of three or more diseases in an individual, represent a significant challenge in healthcare.
- Understanding the prevalence and characteristics of polypathias is crucial for effective public health strategies and clinical management.
Purpose of the Study:
- To investigate the structure and prevalence of polypathias in an adult male rural population.
- To determine the qualitative and quantitative characteristics of multiple co-occurring diseases.
Main Methods:
- A comprehensive population study was conducted involving 1050 males aged 18 and older.
- Data collection focused on identifying and quantifying the presence of multiple chronic conditions (mononozoology, binozoology, and multinozoology).
Main Results:
- Multinozoology was identified in 65.3% of individuals, binozoology in 18%, and mononozoology in 16.7%.
- The prevalence of multinozoology was 604.7 per thousand, binozoology 166.8 per thousand, and mononozoology 154.4 per thousand.
- Diseases of the circulatory system (428.0/1000), respiratory system (400.4/1000), and digestive system (368.9/1000) were the leading conditions contributing to multinozoology.
Conclusions:
- The study highlights the high prevalence of polypathias in the studied rural male population.
- Circulatory, respiratory, and digestive diseases play a primary role in the development of multiple co-occurring chronic conditions.
