环境混合物分析中的估计和错误发现控制

Estimation and false discovery control for the analysis of environmental mixtures

Srijata Samanta, Joseph Antonelli

摘要:

环境混合物的分析在环境流行病学中越来越重要,这种分析的关键目标之一是确定与不利健康结果相关的暴露及其相互作用。典型的方法利用灵活的回归模型结合变量选择,以确定重要的风险敞口,并估计与感兴趣的结果的潜在非线性关系。尽管这种兴趣激增,但迄今为止还没有任何方法可以在识别暴露和相互作用的同时控制暴露选择方面的任何形式的错误率。我们提出了两种新的方法来估计环境混合物的健康影响,同时1)估计和提供有效的推断的整体混合物的效果,2)确定重要的暴露和相互作用,同时控制错误发现率。我们表明,这可以导致大量的功率增益,以检测环境暴露的微弱影响。我们将我们的方法应用于持久性有机污染物的研究,发现我们的方法能够识别比现有方法更多的相互作用。

英文摘要:

The analysis of environmental mixtures is of growing importance in environmental epidemiology, and one of the key goals in such analyses is to identify exposures and their interactions that are associated with adverse health outcomes. Typical approaches utilize flexible regression models combined with variable selection to identify important exposures and estimate a potentially nonlinear relationship with the outcome of interest. Despite this surge in interest, no approaches to date can identify exposures and interactions while controlling any form of error rates with respect to exposure selection. We propose two novel approaches to estimating the health effects of environmental mixtures that simultaneously 1) Estimate and provide valid inference for the overall mixture effect, and 2) identify important exposures and interactions while controlling the false discovery rate. We show that this can lead to substantial power gains to detect weak effects of environmental exposures. We apply our approaches to a study of persistent organic pollutants and find that our approach is able to identify more interactions than existing approaches.
