项目摘要
在美国,与种族和民族有关的健康差异是一个主要的公共卫生问题。
States.多方面的证据表明,人们睡眠质量和数量的差异可能
是这个问题的一部分。在这里,我们希望研究睡眠模式,使用完整的多导睡眠图
数据在一个大的和不同的队列,以更好地了解是什么原因导致一些个人和团体,
不同的睡眠,并将这种睡眠差异与相关的健康结果联系起来。
为了研究睡眠作为与种族/民族相关的健康差异的中介,我们建议
首先,将“睡眠”一词分解为数量性状(目标1)。第二,我们将测试
种族/民族和睡眠特征之间关联的人口统计学调节因素,可以指出
可能的社会经济和社会/环境背景介质(目标2)。最后我们将
通过测试与健康结果的关联来证明这些发现的相关性-主要是
心血管疾病风险和非稳态负荷的测量-以及估计睡眠
种族/民族健康差异(目标3)。
我们将应用一系列有针对性的数据驱动分析方法,从数据科学,机器学习,
计算神经科学和因果建模,以表征个体差异的模式,
睡吧更细致地了解什么是“睡眠不好”是很重要的,因为不同的
睡眠的各个方面可能与人口统计学和生物医学因素有着质的不同联系,
包括年龄、性别、生活方式因素、遗传基因构成、昼夜节律、药物作用
以及目前的身心健康状况。通过解开这个相互关联的变量网络,
我们将能够更好地理解--并改善--众多因素的影响,
可能会导致睡眠中的种族/民族差异,从而也会导致健康状况的差异。
英文摘要
Project Summary
Health disparities associated with race and ethnicity are a major public health issue in the United
States. Multiple lines of evidence suggest that differences in people's quality and quantity of sleep may
account for part of this problem. Here we wish to study patterns of sleep, using full polysomnography
data in a large and diverse cohort, to better understand what causes some individuals and groups to
differ in their typical sleep, and to link this variation in sleep to relevant health outcomes.
In order to study sleep as a mediator of health disparities associated with race/ethnicity, we propose to
first unpack the “sleep” term into profiles of quantitative traits (Aim 1). Second, we will test for
demographic moderators of the associations between race/ethnicity and sleep traits, which can point to
likely socioeconomic and social/environmental contextual mediators (Aim 2). Finally, we will
demonstrate the relevance of these findings by testing for association with health outcomes – primarily
cardiovascular disease risk and measures of allostatic load – and estimating the extent to which sleep
accounts for racial/ethnic health disparities (Aim 3).
We will apply a targeted array of data-driven analytic methods, from data science, machine learning,
computational neuroscience and causal modeling, to characterize individual differences in patterns of
sleep. A more nuanced understanding of what constitutes “poor sleep” is important because different
aspects of sleep are likely to have qualitatively different links to demographic and biomedical factors,
including age, sex, lifestyle factors, inherited genetic makeup, circadian rhythms, medication effects
and current state of physical and mental health. By disentangling this network of inter-related variables,
we will be better positioned to understand – and ameliorate – the effects of the numerous factors that
can induce racial/ethnic disparities in sleep, and consequently, in health too.
