Introduction
Recurrent cough is little researched in adults. We investigated the prevalence, risk factors, and consequences of recurrent cough, and compared the results to those of isolated chronic cough.
Methods
Cross-sectional email survey in an elderly community-based population. Recurrent cough was defined as ≥ 3 cough episodes within one year (each lasting ≥ 1 week) and no current chronic cough. Isolated chronic cough was defined as current cough lasting ≥ 8 weeks and no recurrent cough.
Results
The prevalence of recurrent cough was 3.8% among all respondents (n = 5983). Recurrent cough was associated with asthma (aOR 3.32 (95% CI 2.13–5.18)), chronic rhinosinusitis (2.91 (1.89–4.46)), family history of chronic cough (2.59 (1.88–3.56)), analgesic intolerance (2.13 (1.27–3.57)), male gender (1.92 (1.39–2.66)), gastro-esophageal reflux disease (1.73 (1.21–2.47)), obstructive sleep apnoea (1.69 (1.23–2.32)), symptom sum (1.12 per symptom (1.03–1.22)), and younger age (0.96 per year (0.93–1.00)).
Isolated chronic cough was associated with chronic rhinosinusitis (3.45 (2.39–4.97)), asthma (2.17 (1.38–3.41), gastro-esophageal reflux disease (1.80 (1.32–2.47)), family history of chronic cough (1.80 (1.35–2.41)), obstructive sleep apnoea (1.49 (1.12–2.00)), symptom sum (1.18 per symptom (1.10–1.27)), and body mass index (0.96 per unit (0.93–1.00)).
Among subjects with recurrent and isolated chronic cough, the prevalence of depressive symptoms were 7.7% and 4.2%, p = 0.11, the Leicester Cough Questionnaire total scores 15.2 (14.6–15.8) and 16.3 (16.0–16.6), P = 0.001, and the mean number of yearly cough-related doctor`s visits 0.58 (0.45–0.71) and 0.36 (0.19–0.53), P = 0.007, respectively.
Conclusion
The risk factors and consequences of recurrent and isolated chronic cough were comparable. Recurrent cough seems beneficial to address in cough evaluation.
