Epidemiology of chronic non specific respiratory disease and the smoking-control program in young people

In an epidemiological study in the Kolin-District, Czechoslovakia, the percentage of cigarette-smokers was 57% of the male inhabitants aged 15 years and over, and 14% of the females of the same age group. The greatest proportion of cigarette smokers was in the age-group 25-34 years. The prevalence of chronic bronchitis was 13% of all males aged 15 years and over, and 4% of all females. An association of chronic bronchitis with age and smoking habits was found, in both sexes. In another study in the Prague-District No. 7 the smoking habits of male adolescents were related to their socio-economic status. Conclusions of epidemiological studies are important for the formulation and accomplishment of smoking-control program in young people. Health education should encourage school-children and adolescents by methods corresponding to their age to participate actively in the formation of a healthy style of their life.
