Of the 249 children aged 5 to 9 years who live on Easter Island, 220 underwent complete otolaryngological evaluation. Twenty children were found to have otitis media (acute, chronic, or both). Three of these children were genetically impure natives, nine were of mixed parentage, and eight were "continentals" (with a birth origin other than the island). None of the genetically pure natives had otitis media. Our data show that, in a population with all factors in common except for familial and racial background, the point prevalence of otitis media is higher in children of mixed or continental origin than in genetically pure native children. The high prevalence of otitis media in children of mixed parentage and in one particular family of European ancestry suggests the presence of intrinsic or pronicity factors that are seemingly transmissible.
在复活节岛生活的249名5至9岁儿童中，220名接受了全面的耳鼻喉科评估。发现20名儿童患有中耳炎（急性、慢性或两者皆有）。这些儿童中有3名是基因不纯的本地人，9名是混血儿，8名是“大陆人”（出生于该岛以外）。基因纯正的本地人中没有一人患有中耳炎。我们的数据表明，在除家族和种族背景外所有因素相同的人群中，混血或大陆血统儿童的中耳炎点患病率高于基因纯正的本地儿童。混血儿儿童以及一个特定欧洲血统家族中中耳炎的高患病率表明存在似乎具有遗传性的内在或倾向性因素。
