波士顿、堪萨斯城和圣地亚哥哮喘患儿家庭环境的相对霉臭指数(ERMI)较高
2012/12/31
摘要
目的:有水损的家庭,霉菌与哮喘有关。本试验旨在测试一个新的标准,用以定量哮喘患儿家庭霉菌暴露,散布在美国的3个大城市承担了本项试验。
方法:环境相对霉臭指数(ERMI)标准由美国环境保护署和住房及城市发展部(HUD)研制,旨在对美国家庭霉菌污染进行定量。本研究对美国波士顿、堪萨斯城和圣地亚哥三个城市的哮喘患儿家庭ERMI进行检测。
结果:波士顿(n = 76)、堪萨斯城(n = 60)和圣地亚哥(n = 93)哮喘患儿家庭的ERMI显著高于2006年HUD美国健康家庭调查(AHHS)中相同地理区域随机选择家庭的ERMI(后者分别为n = 34, 22和28)。总之,哮喘患儿家庭的平均ERMI为8.73,而AHHS家庭的平均ERMI为3.87。此外,堪萨斯城轻度、中度和重度持续性哮喘患儿家庭的平均ERMI为12.4,而仅有轻度间歇性哮喘患儿的家庭,ERMI 平均值为7.9。检测的所有霉菌中,黑曲霉是唯一一个在所有3个城市哮喘患儿家庭显著增加的霉菌。
结论:美国三个大城市哮喘患儿的家庭ERMI较高。

Abstract
OBJECTIVE: Mold in water-damaged homes has been linked to asthma. Our objective was to test a new metric to quantify mold exposures in asthmatic children’s homes in three widely dispersed cities in the United States.
METHODS:The Environmental Relative Moldiness Index (ERMI) metric was created by the US Environmental Protection Agency, with assistance by the Department of Housing and Urban Development (HUD), to quantify mold contamination in US homes. The ERMI values in homes of asthmatic children were determined for the three widely dispersed cities of Boston, Kansas City, and San Diego.
RESULTS:Asthmatic children in Boston (n = 76), Kansas City (n = 60), and San Diego (n = 93) were found to be living in homes with significantly higher ERMI values than were found in homes randomly selected during the 2006 HUD American Healthy Homes Survey (AHHS) from the same geographic areas (n = 34, 22, and 28, respectively). Taken together, the average ERMI value in the homes with an asthmatic child was 8.73 compared to 3.87 for the AHHS homes. In addition, Kansas City homes of children with "Mild, Moderate, or Severe Persistent Asthma" had average ERMI value of 12.4 compared to 7.9 for homes of children with only "Mild Intermittent Asthma." Aspergillus niger was the only mold of the 36 tested which was measured in significantly greater concentration in the homes of asthmatic children in all three cities.
CONCLUSION:High ERMI values were associated with homes of asthmatic children in three widely dispersed cities in the United States.
