Health-related quality of life in asthma measured by the World Health Organization brief questionnaire (WHO-BREF) and the effect of concomitant allergic rhinitis-A population-based study.

Although asthma and AR negatively impact HRQoL independently, concomitant asthma and AR are worse. Uncontrolled asthma underpins poor QoL in asthma because QoL is not impaired in controlled disease. This underscores the need for recognition and treatment of AR in asthma and reinforces the benefits of achieving asthma control as a priority in asthma treatment.
