A medical study found that children (aged six to eleven) ( who had been enrolled at large daycare centers as toddlers) had about one-third as many colds as children who had stayed home .

교수님 found의 목적어로서 온 that절 이후의 문장에 의문이 가서 질문드립니다. aged는 여기서 children 을 수식해 주는 구조인것 같은데 뒤에 six to eleven이라는 목적어를 수반하여 나왔습니다. 해서 aging이 aged로 잘못나온것으로 판단되는데 아닌가요??
