The prevalence was higher in Australia, Europe, America (11–18%) and much lower in Asia (4%) and Africa (2%), even after adjusting for smoking. The majority of the studies used the 3-month chronic bronchitis definition, but even in studies using the same 8-week cut-off, variations still persist: UK (12%) [2], Finland (7.2%) [3], Germany (5%) [4], Denmark (4%) [5], South Korea (2.6%) [6], Japan (2.2%) [7], Nigeria (1.1%) [8]. The reasons for these variations, even in geographically similar countries, are unclear.French speakers have a 4% lower incidence of chronic cough than English speakers in the CLSA, but English speakers from Quebec, Newfoundland and Labrador, and Nova Scotia also have a lower risk of developing chronic cough https://bit.ly/3qAd3MfThis research was made possible using the data/biospecimens collected by the Canadian Longitudinal Study on Aging (CLSA). Funding for the CLSA is provided by the Government of Canada through the Canadian Institutes of Health Research under grant reference LSA 94473 and the Canada Foundation for Innovation as well as the following provinces: Newfoundland, Nova Scotia, Quebec, Ontario, Manitoba, Alberta and British Columbia. This research has been conducted using the CLSA dataset, Baseline and Follow-up 1 Comprehensive Dataset, under Application Number 1909024. The CLSA is led by P. Raina, C. Wolfson and S. Kirkland. The opinions expressed in this manuscript are the author's own and do not reflect the views of the CLSA. The final manuscript was reviewed and approved by the Publication Review Committee of the CLSA. ER -
