A community study of the incidence of clinically diagnosed otitis media and middle ear effusions was undertaken in the City of Galveston, Texas, based on a random sample of records of patients aged 0-8 years receiving medical care from four major sources during 1975. No overall sex or ethnic differences were observed in association with otitis media. Thirty-five per cent of the sample had at least one episode of otitis media during 1975 and, of these, one-third had two or more episodes, yielding a conservative annual incidence rate of 55.1 per cent for this age group. The overall age-specific incidence pattern indicated the highest rates for the 0-2 year age group (71 to 114 episodes per 100 children) with a steady decline in risk with increasing age. Infants who received an initial diagnosis within the first 12 months of life experienced significantly more episodes of otitis during a two-year period than did children who received an initial diagnosis after one year of age. Seasonal patterns of otitis media were comparable with those reported in other studies. Analysis by birth month of children who experienced repeated episodes of otitis indicated an increased number of children born in the late summer and fall.
基于1975年从四个主要医疗来源接受治疗的0至8岁患者记录的随机样本，在得克萨斯州加尔维斯顿市开展了一项关于临床诊断中耳炎和中耳积液发病率的社区研究。未观察到与中耳炎相关的总体性别或种族差异。1975年，35%的样本至少有一次中耳炎发作，其中三分之一有两次或更多次发作，该年龄组的保守年发病率为55.1%。总体年龄别发病率模式显示，0至2岁年龄组发病率最高（每100名儿童中有71至114次发作），且随着年龄增长风险稳步下降。在出生后12个月内首次确诊的婴儿在两年期间患中耳炎的次数明显多于1岁后首次确诊的儿童。中耳炎的季节性模式与其他研究报告的模式相似。对反复患中耳炎儿童的出生月份进行分析表明，夏末和秋季出生的儿童数量有所增加。
