哮喘联盟

   摘要
   本项研究在2558例非西班牙裔白种人和来自65个洛杉矶社区的西班牙裔儿童中，评估民族和西班牙裔种族，孕产妇和出生儿童以及祖籍与哮喘之间的关系。一系列双层模型被用于评估哮喘儿童民族、种族和祖籍的独立影响因素。哮喘终生发病率占儿童的9%，且在整个西班牙裔和非西班牙裔白种人中无显著性差异。但在经过充分校正的模型中，非墨西哥起源的西班牙裔儿童与非西班牙裔白种儿童相比，报告的哮喘发病率更高。保护性出生的影响也被在国外出生母亲所生儿童和美国出生母亲所生儿童中进行了比较。我们的研究证明西班牙裔种族和孕产妇出生地对儿童哮喘的异质性。这一结果表明，仅只考虑民族/种族的划分可能掩盖那些增加儿童哮喘风险的原因。

Abstract
This study examined the relationship between race and Hispanic ethnicity, maternal and child nativity, country of origin and asthma among 2,558 non-Hispanic white and Hispanic children across 65 Los Angeles neighborhoods. A series of two-level multilevel models were estimated to examine the independent effects of race, ethnicity, and country of origin on childhood asthma. Lifetime asthma prevalence was reported among 9 % of children, with no significant differences between Hispanics and non-Hispanic whites overall. However, in fully adjusted models, Hispanic children of non-Mexican origin reported higher odds of asthma compared to non-Hispanic white children. A protective nativity effect was also observed among children of foreign born mothers compared to US born mothers. Our study provides evidence in support of the heterogeneity of childhood asthma by Hispanic ethnicity and maternal nativity. These findings suggest moving beyond solely considering racial/ethnic classifications which could mask subgroups at increased risk of childhood asthma.
