Final answer:
Asthma is a respiratory condition that can cause complications in both adults and children, and it is frequently associated with hospitalizations, especially in children.
Step-by-step explanation:
From the information provided, we have found that asthma and lung disease are both associated with complications in the respiratory system, where the alveoli can become inflamed, potentially leading to increased hospitalization. However, the categories that the question refers to are not directly mentioned in the references. If the categorization is about diseases that cause complications in both adults and children, asthma would indeed fit since it affects both groups and leads to such complications. Notably, asthma is highlighted as the most frequent cause of hospitalization in children and also affects a significant proportion of adults.
