项目摘要
睡眠不足(IS),源于睡眠呼吸暂停、轮班工作、失眠、每周工作40小时以上、
不良的睡眠环境和/或自愿减少就寝时间,与患高血压的风险增加有关。
心血管疾病(CVD)标记物(高血压、胰岛素抵抗、血脂异常和
动脉僵硬)、炎症标志物(白介素6、肿瘤坏死因子-α和C反应蛋白)作为
以及脑部损伤。令人信服的证据表明,在睡眠不足(IS)方面存在种族/民族差异,
黑人患IS的风险是白人的三倍。差异可能由生理原因引起
和遗传因素,但最近的证据表明,环境和心理社会因素也是关键
决定因素。这项研究将利用多层次框架中的创新动态建模来描绘

英文摘要
Project Summary
Insufficient sleep (IS), stemming from sleep apnea, shift work, insomnia, working over 40 hr./week,
unfavorable sleep environments and/or volitional reduction of bedtime, is associated with increased risk of
cardiovascular disease (CVD) markers (elevated blood pressure, insulin resistance, dyslipidemia and
arterial stiffness), inflammatory markers (interleukin-6, tumor necrosis factor-α, and C-reactive protein) as
well as with brain injury. Compelling evidence shows racial/ethnic disparities in insufficient sleep (IS), with
blacks exhibiting a three-fold greater risk of IS relative to whites. Disparities might arise from physiologic
and genetic factors, but recent evidence suggests environmental and psychosocial factors are also critical
determinants. This study will utilize innovative dynamic modeling in a multi-level framework to delineate the
psychosocial and environmental determinants (associative factors) of actigraphic IS and its putative
associations with adverse health outcomes among blacks. Individual- and contextual-level data will be
captured using novel home-based recordings and GIS data to model the environmental context where sleep
occurs. The proposed study will leverage success of the NYU Sleep Disparity Workgroup led by Dr. Jean-
Louis (PI), who has been conducting community-engaged sleep research for over 10 years. The workgroup
comprises outstanding investigators with expertise in sleep and circadian rhythm, CVD, brain health, health
disparities, translational behavioral medicine, and multi-level dynamic modeling. The study will benefit from
experience of our standing Community Steering Committee, enabling recruitment of 560 blacks in various
venues to participate in weeklong home studies to achieve proposed study aims. The multidisciplinary team
will: 1) identify psychosocial (social support, discrimination, and attitudes/beliefs) and environmental
(household [density, noise, light, and temperature], socioeconomic position, social capital, and
neighborhood [built environment]) factors that are associated with IS; ascertain effects of IS on (a) markers
of CVD (obesity, BP, lipid profile, and glucose/ HbA1C) and inflammation (IL-6, IL-10, and TNF-α) and on
(b) markers of brain injury (tau, amyloid-β, neurofilament light, homocysteine, and glial fibrillary acidic
protein; and develop profiles of blacks with IS-related adverse health outcomes using individual- and
environmental-level data applying innovative multi-level dynamic modeling tools (Bayesia Belief Network
and Agent-Based Simulation). This study will provide evidence to delineate factors underlying greater rates
of IS among blacks and explain putative associations with markers of CVD, inflammation, and brain injury.
These data will provide the foundation for longitudinal studies assessing causal effects of IS on these novel
markers and interventions to mitigate adverse effects of IS on health outcomes.
