More than 75 percent of the cases of acute suppurative otitis media (ASOM) among Indian children observed from May 1974 through March 1979 were experienced by preschool children. About 60 percent of the children observed during the first year of life had one or more attacks of ASOM, and 34 percent had two or more. Among those who had ASOM before their first birthday, 75 percent of the attacks occurred between 3 and 9 months of age. About 73 percent of the initial attacks were recorded during the first year of life among children observed from 3 to 5 years; almost 90 percent occurred before the second birthday. Approximately 75 percent of the second attacks occurred within 4 months of the first. More than 70 percent of the initial attacks before age 1 were followed by 1 or more subsequent attacks during the next 12 months. When the initial attack occurred during the second year of life, subsequent attacks were experienced by less than half as many children. Children at high risk of serious ear disease, including hearing loss, are characterized by having an attack of ASOM before their first birthday followed by a second attack within 4 months of the first. Efforts to control and prevent ASOM should selectively be directed toward this group.
1974年5月至1979年3月期间观察到的印度儿童急性化脓性中耳炎（ASOM）病例中，超过75%发生在学龄前儿童身上。在出生后第一年观察到的儿童中，约60%曾患过一次或多次ASOM，34%曾患过两次或更多次。在一岁前患过ASOM的儿童中，75%的发作发生在3至9个月大之间。在3至5岁儿童中，约73%的首次发作记录在出生后第一年；近90%发生在第二个生日之前。约75%的第二次发作发生在第一次发作后的4个月内。1岁前的首次发作中，超过70%的儿童在接下来的12个月内会有1次或更多次后续发作。当首次发作发生在第二年时，经历后续发作的儿童不到一半。患有严重耳部疾病（包括听力丧失）高风险的儿童，其特征是在一岁前患过一次ASOM，随后在第一次发作后的4个月内又发作一次。控制和预防ASOM的努力应针对性地指向这一群体。
