This study used data from 231,460 adults (19,195 current asthma, 11,972 ever asthma, 200,293 never asthma) enrolled in the National Health Interview Survey (NHIS), a nationwide, large-scale, cross-sectional interview survey of the civilian non-institutionalized population in the US.
It showed that depression/anxiety are linked to elevated asthma risk and poorer asthma outcomes. Patients who have achieved asthma remission also experienced more depression/anxiety and that depression/anxiety were associated with reduced likelihood of asthma remission. Furthermore, patients with depression/anxiety were at a higher risk of allergic comorbidities.
