How many nights per month characterize Mild Persistent asthma in the adult population?

The characterization of Mild Persistent asthma in adults is defined by how often nighttime symptoms occur. For adults with Mild Persistent asthma, experiencing nighttime symptoms more than twice a month but less than once a week is a key clinical marker. This aligns with the definition that indicates having symptoms on average of three nights per month. Therefore, the correct answer reflects this criteria, aligning with established guidelines for asthma classification that emphasize the frequency of nighttime awakenings as a measure of symptom severity. Understanding these classifications is crucial for proper diagnosis and treatment planning in asthma management.
