To assess the incidence of secretory otitis media in children minded at home we examined 210 children not attending kindergarten or municipal day care. Of these children 117 were minded exclusively at home or in private day care with up to 2 children. Tympanometry was carried out 6 times at 2-week intervals. Secretory otitis media (SOM) of more than 3 months' duration was found in 17% of the one-year-olds and in 6% of the total series. In the age range 1-5 years the incidence was from 0.35 to 0.19/child/month, and the mean for the total group was 0.26/child/month.
为评估在家照料儿童中分泌性中耳炎的发病率，我们检查了210名未上幼儿园或市立日托机构的儿童。在这些儿童中，117名仅在家中或在私人日托机构照料，日托机构中儿童最多2名。每隔2周进行1次鼓室导抗图检查，共检查6次。在1岁儿童中，发现病程超过3个月的分泌性中耳炎（SOM）的比例为17%，在整个研究组中为6%。在1至5岁年龄组中，发病率为0.35至0.19/儿童/月，整个组的平均发病率为0.26/儿童/月。
