Hearing losses at 15 years of age were investigated in a material of 11,780 children born in Northern Finland in 1966 and followed-up since pregnancy. Two samples of the whole material, one representing a sample of 413 children with reported impaired hearing, and the other of 959 children with reported normal hearing were calculated to represent a total material of 11,748 cases. The correlation between the reported hearing and the audiometry results was very good. In the calculated material, 1,708 (14.6%) of the children exhibited a hearing loss exceeding 20 dB in at least one frequency in their school audiograms. The incidence of secretory otitis media as a risk diagnosis among those with impaired hearing was significantly higher than among those with normal hearing. Most of the hearing losses were found in the high frequencies.
对1966年出生于芬兰北部且自孕期起便接受随访的11780名儿童进行了15岁时听力损失情况的调查。从整个样本中抽取了两个样本，一个样本包含413名报告有听力受损的儿童，另一个样本包含959名报告听力正常的儿童，经计算这两个样本代表了总共11748个病例。报告的听力情况与听力测定结果之间的相关性非常好。在经计算的样本中，1708名（14.6%）儿童在学校听力图中至少有一个频率的听力损失超过20分贝。分泌性中耳炎作为听力受损儿童的风险诊断，其发病率显著高于听力正常的儿童。大多数听力损失出现在高频。
