A prospective study of 337 children was carried out during a 3-month period. The purpose of the study was to evaluate the importance of indoor environmental factors in homes and day-care institutions for the incidence of middle ear effusion (MEE). The indoor environmental factors measured in institutions were carbon dioxide, temperature, and relative humidity. Conditions in the homes were assessed by a questionnaire. Middle ear effusion was measured by tympanometry. No relationship was found between indoor environmental factors and MEE, with the exception of parental smoking at home, which increased the frequency of MEE in children.
在三个月的时间里对337名儿童进行了一项前瞻性研究。该研究的目的是评估家庭和日托机构中的室内环境因素对中耳积液（MEE）发病率的重要性。在机构中测量的室内环境因素有二氧化碳、温度和相对湿度。通过问卷调查评估家庭环境状况。通过鼓室声导抗测量法测量中耳积液。未发现室内环境因素与中耳积液之间存在关联，但在家中父母吸烟的情况除外，这会增加儿童中耳积液的发生率。
