Daily psychosocial stress and cardiometabolic health of older Chinese Americans

项目摘要 尽管是美国增长最快的移民人口之一，但年长的华裔美国人 在健康研究方面仍未得到充分研究。模范少数民族刻板印象的渗透导致了 忽视了年长的华裔美国人经历的重大劣势和健康负担，特别是 外国出生的年长的华裔美国人。身为少数民族成员的双重劣势和 外国出生的老年华裔美国人面临着经历心理社会压力的高风险， 包括反亚裔种族主义和社会孤立。这些心理社会应激源是穷人的关键风险因素 身体健康，包括心脏代谢健康状况不佳。事实上，现有的研究表明， 中国老年移民移居美国后的心脏代谢健康。然而，在那里 缺乏对心理社会压力源的细粒度表征，以及这些压力源所经历的过程 心理社会应激源影响老年华裔移民的心脏代谢健康。关于这一主题的现有研究 主要集中在非西班牙裔白人或其他少数族裔。为了解决这一差距，我们的目标是通过一项 混合方法方法，以及生态瞬时评估，以确定关键的心理社会 80名华裔老年移民心脏代谢健康相关应激源的研究。具体地说，我们的 建议的目标是：目标1a：调查日常情绪(消极情绪和积极情绪)的中介作用 和唾液皮质醇(一种压力的生物标记)，心理社会应激源(例如，种族 歧视)影响全身炎症(CRP、IL-6)和代谢综合征；目标1b：探索关键 社会文化因素(生活在种族飞地、英语水平、社会经济地位)将削弱 目标1a和目标2中审查的联系：确定其他文化、环境、家庭和个人 通过以下途径进一步解释心理社会压力和心脏代谢健康之间关系的因素 对来自AIM 1的16名参与者进行半结构化访谈。 有助于我们理解关键的心理社会应激源和相关的生物心理过程 导致老年中国移民心脏代谢健康状况不佳。因此，该项目将指导 设计未来文化量身定做的、对时间敏感的个性化心理社会干预措施，旨在减少 心脏代谢健康方面的种族差异，并促进老年华裔美国人的健康公平。

Project Summary Despite being one of the fastest-growing immigrant populations in the United States, older Chinese Americans remain understudied in health research. The penetration of the model minority stereotype has caused the overlook of significant disadvantages and health burdens experienced by older Chinese Americans, particularly foreign-born older Chinese Americans. The double disadvantage of being a member of an ethnic minority and foreign-born puts foreign-born older Chinese Americans at high risk of experiencing psychosocial stressors, including anti-Asian racism and social isolation. These psychosocial stressors are key risk factors for poor physical health, including poor cardiometabolic health. Indeed, existing studies have shown a fast decline in cardiometabolic health after immigrating to the United States among older Chinese immigrants. However, there is a lack of a fine-grained characterization of psychosocial stressors and the processes through which these psychosocial stressors affect cardiometabolic health in older Chinese immigrants. Existing studies on this topic were largely focused on non-Hispanic Whites or other ethnic minorities. To address this gap, we aim to adopt a mixed-methods approach, along with the ecological momentary assessment, to identify the key psychosocial stressors related to cardiometabolic health in a sample of 80 older Chinese immigrants. Specifically, our proposed aims are: Aim 1a: Investigate the intermediate role of daily emotion (negative and positive emotion) and salivary cortisol (a biological marker of stress) through which psychosocial stressors (e.g., racial discrimination) affect systemic inflammation (CRP, IL-6) and metabolic syndrome; Aim 1b: Explore whether key sociocultural factors (living in ethnic enclaves, English proficiency, socioeconomic status) will attenuate the associations examined in Aim 1a; and Aim 2: Identify additional cultural, environmental, family, and individual factors that further explain the association between psychosocial stress and cardiometabolic health through semi-structured interviews in a subsample of 16 participants from Aim 1. Findings from this proposed study will contribute to our understanding of key psychosocial stressors and related biopsychological processes contributing to poor cardiometabolic health in older Chinese immigrants. As a result, this project will guide the design of future culturally-tailored, time-sensitive, personalized psychosocial interventions that aim to reduce racial disparities in cardiometabolic health and promote healthy equity in older Chinese Americans.
