The primary data for Project 1 will come from an R21 funded by NIEHS (R21 ES 014891-01A1, Influences of genetics and air pollution exposures on birth outcomes.) Part A ofthe R21 uses refined air pollution and traffic density data to examine their influence of on adverse birth outcomes such as low birth weight and premature birth. Part B of the R21 evaluates the feasibility of assembling a birth-cohort to provide saliva samples for the analysis of genetic and epigenetic susceptibility to the effects of air pollution. During the pre-Center funding, we will obtain additional spatially-refined exposure data from the prenatal periods of over 300, 000 birth in the San Joaquin Valley of California. We will implement novel statistical methods to evaluate possible longitudinal and joint of effects of pollutant mixtures on birth outcomes. In addition to the spatially-refined air pollution data, detailed traffic counts and density data, census and neighborhood-level characteristics, and for some demographic variables, simulated individual-level data will be used to control for confounding and identification of susceptible subgroups. It will evaluate the feasibility of a similar study design to examine numerous important children's health outcomes. Examples of outcomes include asthma, autism spectrum disorders, cancer, and metabolic disorders such as obesity. Genetic samples will be obtained from mothers/children identified in Part B ofthe R21 and stored for analysis during a full Center grant. Extensive investigation will be done to identify the proper set of genetic polymorphisms that may influence susceptibility to the effects of air pollution and those that are associated with preterm birth. Similar investigations will be done to identify genetic polymorphism associated with the risk ofthe other health outcomes listed. We have chosen a cost-efficient approach by making use of an exposure dataset of unparalleled richness with respect to specific pollutants (CRPAQS) and existing birth certificates files while at the same time developing a birth cohort and specimen bank for future research. Our study will also make use of modeling strategies developed for other funded studies conducted within the same region.

项目1的主要数据将来自NIEHS资助的R21（R21 ES 014891- 01 A1，遗传学和空气污染暴露对出生结果的影响）。R21报告的A部分使用精确的空气污染和交通密度数据来研究它们对不良出生结果的影响，如低出生体重和早产。R21的B部分评估了收集出生队列的可行性，以提供唾液样本，用于分析对空气污染影响的遗传和表观遗传易感性。在中心前期的资助中，我们将从加州圣华金河谷超过30万名新生儿的产前时期获得额外的空间精确暴露数据。我们将实施新的统计方法，以评估污染物混合物对出生结果可能的纵向和联合影响。除了空间上精确的空气污染数据、详细的交通计数和密度数据外， 对于某些人口统计学变量，将使用模拟的个人水平数据来控制 用于混淆和识别易感亚组。它将评估类似研究的可行性 旨在检查许多重要的儿童健康结果。结果的例子包括哮喘， 自闭症谱系障碍、癌症和代谢障碍如肥胖症。将从R21的B部分中确定的母亲/儿童中获得遗传样本，并将其储存以供在中心全额资助期间进行分析。将进行广泛的调查，以确定可能影响对空气污染影响的易感性以及与早产相关的遗传多态性。将进行类似的调查，以确定与列出的其他健康结果的风险相关的遗传多态性。我们选择了一种具有成本效益的方法，即利用特定污染物（CRPAQS）和现有出生证明文件方面无与伦比的丰富暴露数据集，同时为未来的研究开发出生队列和标本库。我们的研究还将利用为同一地区内进行的其他资助研究开发的建模策略。
