51% of adult patients with asthma had clinically significant anxiety

Of these only 21% had already been diagnosed and were receiving treatment.
Females reported significantly higher scores than males. More females (66.3%) registered clinically significant levels of anxiety as compared with males.

There was a positive correlation between the Beck Anxiety Inventory (BAI) score and the prescribed dose of inhaled glucocorticoids. There was also a positive correlation between anxiety and the number of medicines taken by patients.

Physicians treating patients with asthma should be aware of the association between asthma and anxiety. Always assess patients for the possibility of anxiety disorders as part of asthma management plans.
