Our aim was to determine the prevalence of chronic cough in a representative adult population cohort, particularly cough that is not associated with diagnosed respiratory conditions, and examine the impact on health status and psychological health. Others studies are limited by the lack of use of a validated instrument of psychological health. However, the few studies that have evaluated the impact of cough on health status or psychological health have sampled from specialist clinic populations rather than the general population. Chronic cough is also associated with psychosocial problems that may be more pronounced than physical effects.
Successful treatment of cough often leads to major improvement in quality of life. Where population data exist they are limited by methodological problems, including use of selected age groups, self selection of questionnaire respondents, failure to differentiate between acute cough due to infection and chronic cough or a lack of information on other respiratory conditions making it difficult to differentiate the impact of chronic cough from that of airways diseases such as asthma.Ĭhronic cough is associated with adverse effects on health-related quality of life. The prevalence of chronic cough (lasting more than eight weeks) has been variously reported at 10% to 30%.
Most reports of the prevalence of chronic cough in adults originate from specialist cough clinics and therefore reflect the experience of chronic cough in secondary or tertiary care. However, data on the prevalence of cough lasting more than eight weeks in the general population are scarce. Inquiring about cough in those with mental health problems may identify reversible morbidity.Ĭough is the commonest symptom seen in primary care, and chronic cough is one of the most frequent reasons for new referrals to specialist pulmonologists. Attention to cough is indicated in patients with obesity, psychological symptoms or smokers. ConclusionsĬhronic cough is a major cause of morbidity. Among non-smokers only, all cough was significantly more common in men, those with severe mental health disturbance and obesity. In multiple logistic regression models, at follow-up, dry chronic cough without sputum production was significantly more common in males (OR 1.5, 95% CI 1.1, 1.9), current smokers (OR 4.9, 95% CI 3.4, 7.2), obesity (OR 1.9, 95% CI 1.3, 2.9), use of ACE inhibitors (OR 1.8, 95% CI 1.1, 2.9), severe mental health disturbance (OR 2.1, 95% CI 1.4, 3.1) and older age (40-59 years OR 1.7 95% CI 1.2, 2.4 ≥ 60 years OR 2.1 95% CI 1.3, 3.5). Of the 3355 people without identified lung disease at baseline, 18.2% reported chronic cough. Questionnaires assessed demographics, lifestyle risk factors, quality of life, mental health and respiratory symptoms, doctor diagnosed conditions and medication use.

Clinical assessment included spirometry, anthropometry and skin tests. North West Adelaide Health Study (n stage 1 = 4060, stage 2 = 3160) is a representative population adult cohort. Our aim was to determine the prevalence of chronic cough that is not associated with diagnosed respiratory conditions and examine the impact on health status and psychological health, in a representative adult population cohort Methods Although chronic cough is a common problem in clinical practice, data on the prevalence and characteristics of cough in the general population are scarce.
