Conclusion : Aspirin‐intolerant asthma identified in the general population was associated with a high burden of symptoms, uncontrolled disease and a high morbidity. Increasing body mass index increased the risk of aspirin‐intolerant asthma in a dose‐response manner.

A number of risk factors, including obesity and current smoking, were considerably stronger for aspirin‐intolerant asthma than for aspirin‐tolerant asthma.
