The objective of this study was to analyze seeking medical attention and the use of spirometry in individuals with chronic respiratory symptoms and to compare these results with those obtained in the 2005 and 2011 surveys. Material and Methods: A cross-sectional, observational, epidemiological study was conducted via phone interview in December 2020 in Spain, with a representative sample from 17 autonomous communities.

Results: From 89,601 phone contacts, a total of 6534 respondents were obtained. A total of 24.8% reported having some chronic respiratory symptom, and 17.9% reported a respiratory disease.
