Effect of medical and biological factors on neurological manifestations of vertebral osteochondrosis in residents of the southern Altai Mountains.

We performed clinical and epidemiological study of 1508 residents living in the southern Altai Mountains and belonging to two subethnic groups (Telengite and Altai Kizhi). The incidence of neurological manifestations of vertebral osteochondrosis in people older than 17 years was 627.6 26.4%. The results show that genetic factors (hereditary polygenic predisposition) play a major role in the development of neurological manifestations of vertebral osteochondrosis. Premorbid state of the organism and diseases of various organs and systems promote the development of this neurological disorder.

Constitution and anthropometric parameters in indigenous population of Southern Altai Mountains.

Analysis of anthropometric parameters of 645 indigenous residents of Southern Altai Mountains belonging to two subethnic groups (165 Telengites and 480 Altai-Kizhi) revealed constitutional characteristics distinguishing these groups from each other and from Europeans. Differences in body length and weight, distribution by constitution types, sexual dimorphism, and AB0 blood groups were detected. The specific features of constitution together with environmental factors can determine predisposition of individuals belonging of these subethnic groups to some diseases.
