几项研究报告了日托中心（DCC）的室内空气质量（IAQ）较差，其他研究表明，参加日托中心的儿童患呼吸道和胃肠道感染的风险增加。本研究的目的是调查是否有一个在DCC通风和托儿所儿童病假之间的关联。获得了20个儿童发展中心的635名儿童11周内的儿童病假数据。通风测量包括三个代理的通风：空气交换率（ACR）与衰减法测量，ACR测量的全氟化碳示踪气体（PFT）的方法，并在1周内测量的CO2浓度。除了两个DCC外，所有DCC都有平衡的机械通气系统，这可以解释测量到的低CO2水平。CO2的平均浓度为643 ppm，仅在一个DCC中超过1000 ppm。一个统计学上显着的反比关系，发现与衰减方法测量的病假天数和ACR的粗和调整后的分析，减少12%的病假天数每小时增加的ACR与衰减方法测量。这项研究表明，幼儿园儿童的病假和通风的DCC之间的关系，与衰减法测量。
Several studies have reported poor indoor air quality (IAQ) in day care centers (DCCs), and other studies have shown that children attending them have an increased risk of respiratory and gastrointestinal infections. The aim of this study was to investigate whether there is an association between ventilation in DCCs and sick leave among nursery children. Data on child sick leave within an 11-week period were obtained for 635 children attending 20 DCCs. Ventilation measurements included three proxies of ventilation: air exchange rate (ACR) measured with the decay method, ACR measured by the perfluorocarbon tracer gas (PFT) method, and CO2 concentration measured over a 1-week period. All but two DCCs had balanced mechanical ventilation system, which could explain the low CO2 levels measured. The mean concentration of CO2 was 643 ppm, exceeding 1000 ppm in only one DCC. A statistically significant inverse relationship between the number of sick days and ACR measured with the decay method was found for crude and adjusted analysis, with a 12% decrease in number of sick days per hour increase in ACR measured with the decay method. This study suggests a relationship between sick leave among nursery children and ventilation in DCCs, as measured with the decay method.
