A questionnaire survey using WHO-recommended unified questionnaires was performed in Kharkov to elucidate the role of short-term (less than 3 months yearly) and long-term (greater than 3 months, per 2 years) cough in prediction and diagnosis of chronic bronchitis. Cough prevalence was investigated in 5-year age groups (40-44, 45-49, 50-54, 55-59) and correlated to education level and risk of chronic noninfectious diseases. The study covered a population of 7901 males at the mean age of 49 +/- 2.3 years. A group of active prophylaxis and two reference groups comprised 2001 males from an open population. The trial revealed an increase in cough incidence for smokers, low-educated and aged examinees. It is suggested that social and economic status dependent on educational level may represent a risk of chronic bronchitis not less than occupation, smoking, etc.
