Thirty one of 486 children followed from birth had recurrent croup in the first four years of life. Twenty one were boys, and 10 girls. Recurrent croup occurred significantly more often in families with a positive history of allergy but was not significantly associated with the initial feeding method.
在486名从出生就开始随访的儿童中，有31名在生命的前四年出现复发性喉炎。其中21名是男孩，10名是女孩。复发性喉炎在有过敏家族史的家庭中发生的频率明显更高，但与初始喂养方式没有显著关联。
