In recent decades, several epidemiological studies have been published on acute otitis media (AOM), indicating that the occurrence of AOM is increasing. However, the comparison between the surveys is complicated and biased by several factors, e.g. variable study demography and design and dissimilar diagnostic criteria. The present study was performed with an identical set-up in 1978-9 and 1994-5 to find out potential changes in the occurrence of AOM. All the attacks of AOM among children under 10 years diagnosed by a physician during the 12-month periods 1 June, 1978 to 31 May 1979 and 1 June 1994 to 31 May 1995 were registered retrospectively in two Finnish municipalities. The incidence rate (total number of AOM attacks per 100 child years) was 19 (95% CI 18-21) in 1978-9 and 32 (95% CI 30-34) in 1994-5. The increase in the occurrence of AOM was 68% (95% CI 53-79%, P < 0001).
近几十年来，已经发表了几项关于急性中耳炎（AOM）的流行病学研究，表明AOM的发病率正在上升。然而，这些调查之间的比较很复杂，并且受到几个因素的影响而存在偏差，例如不同的研究人群和设计以及不同的诊断标准。本研究在1978 - 1979年和1994 - 1995年采用相同的设置进行，以找出AOM发病率的潜在变化。在芬兰的两个城市，对1978年6月1日至1979年5月31日以及1994年6月1日至1995年5月31日这12个月期间由医生诊断的10岁以下儿童的所有AOM发作进行了回顾性登记。1978 - 1979年的发病率（每100儿童年AOM发作总数）为19（95%可信区间18 - 21），1994 - 1995年为32（95%可信区间30 - 34）。AOM发病率的增加为68%（95%可信区间53 - 79%，P < 0.001）。
