To evaluate how often a common cold induces secretory otitis media (SOM) two groups of young children were studied. One comprised 373 children aged 9 months to 7 years who were being minded in institutions. The other group consisted of 210 children not minded in day institutions or private day care. This latter group was subdivided into children minded at home or in private day care attended by not more than 2 children (117 children), and the remainder (93 children). Common colds were defined as nasal discharge, and tympanometry was carried out 6 times at 2-week intervals. Among the 1-year-olds common colds induced SOM in 83% of those minded in institutions and in 56% of those minded at home. At the age of 5 years this applied to 20% of both groups.
为评估普通感冒诱发分泌性中耳炎（SOM）的频率，对两组幼儿进行了研究。一组包括373名年龄在9个月至7岁的在机构中托管的儿童。另一组由210名不在日间机构或私立日托所托管的儿童组成。后一组又细分为在家中托管或在不超过2名儿童的私立日托所托管的儿童（117名儿童）以及其余儿童（93名儿童）。普通感冒定义为流鼻涕，并每隔2周进行6次鼓室图检查。在1岁儿童中，机构托管儿童中83%的普通感冒诱发了SOM，在家中托管儿童中这一比例为56%。在5岁时，两组中这一比例均为20%。
