[Nonspecific lung diseases among the population of Western Siberia].

Epidemiological surveys conducted in the city of Novosibirsk and the Novosibirsk region in 1980-1986, revealed a high though unequal prevalence of nonspecific pulmonary diseases among different age, sex and occupational groups of the urban and rural population. Chronic bronchitis ranked first in the structure of chronic nonspecific pulmonary diseases. ARVI and recurrent acute pneumonia, unfavorable working conditions and harmful habits influenced the development of chronic bronchitis. The introduction of a 5-group system of dynamic dispensary observation was conductive to a 2.5-3-fold decrease in temporary disability caused by diseases of the respiratory organs preventing a considerable economic loss.
