PSYCHOSOCIAL ASPECTS OF SODIUM EXCRETION/SENSITIVITY IN BLACKS

这项研究的目的是考察社会经济的影响 静息交感神经系统(SNS)活动状态(SES)， 应激诱导的心血管反应性、钠排泄和钠 黑人女性和男性的敏感性。它还将探索 钠负荷与慢性应激对急性血管的交互作用 反应性。我们希望证明暴露在慢性压力下是 与静息SNS活性升高和钠离子改变有关 新陈代谢。

The purpose of this study is to examine the influence of socioeconomic status (SES) on resting sympathetic nervous system (SNS) activity, stress-induced cardiovascular reactivity, sodium excretion, and sodium sensitivity in Black females and males. It will also explore the interactive effects of a sodium load and chronic stress on acute vascular reactivity. We hope to demonstrate that exposure to chronic stress is associated with heightened resting SNS activity and altered sodium metabolism.
