title: [Epidemiology and strategy for the control of chronic respiratory diseases].
abstract: The conditions of tertiary prevention of chronic bronchitis are determined by prevalence, number of cases of inability to work, time of disease periods and age-depending mortality. An age-specific increase could be proved for all parameters. The critical age-line is about the 50th year of age. 75% of the bronchitis patients under medical care are older than 50 years of age. Measure of care ought to be concentrated on the time before the 50th year of age and on cases of risk. By an earlier beginning of medical care it is possible to increase the efficiency of tertiary prevention.
