项目摘要

PROJECT SUMMARY African-American women have strikingly high rates of coronary heart disease (CHD)-related death and disability compared to women of all other racial/ethnic groups. This excess burden has persisted for decades, and is on the rise among young to middle-aged women. Emerging evidence suggests that sleep disturbance (e.g., short sleep duration, poor sleep continuity) may be an important driver of CHD risk in African-American women; however, because most research on sleep disturbance in African-American women has focused on comparisons to women from other racial/ethnic groups, there are substantial gaps in knowledge about factors that might promote and protect against sleep disturbance within African-American women. Such information will be critical for the development of targeted intervention efforts to improve sleep and ultimately reduce CHD risk in this population. The proposed project is designed to examine whether and how “Shifting” -- a novel, sociocultural phenomenon hypothesized to be salient among African-American women-- might impact sleep disturbance among this group. Shifting is defined as a seemingly adaptive practice in which African-American women engage in self-altering behaviors to both fit in with dominant society and accommodate African- American men. Although documented in qualitative studies and anecdotal accounts of African-American women’s experiences over the past 30 years, empirical studies of shifting have only recently emerged, and none have focused on health. We have compelling preliminary data on early middle aged African-American women, indicating that reports of Shifting (e.g., changing speech patterns, downplaying accomplishments, self- silencing) are associated with subjective sleep disturbance and body mass index (BMI), not explained by depressed affect, or discriminatory or other chronic stressors. Building on this preliminary data, we will examine the prospective interrelationships among shifting, day-to-day psychological processes, and sleep disturbance in 400 African-American women aged 35-54 from a range of SES backgrounds. Shifting and subjective sleep quality will be measured with validated questionnaires, and sleep duration and continuity will be assessed via actigraphy over the course of 14 days at baseline, and in order to shed some light on temporality, at a 12-month follow up. In order to provide us with a more in-depth understanding of how shifting might contribute to sleep disturbance on a night-to-night basis, reports of day-to-day stress, negative affect and vigilance will be assessed via daily diaries concurrent with the actigraphy assessment over the 14-day period. Finally, we will examine whether our hypothesized relationships are exacerbated by socioeconomic status (SES), which might increase the likelihood of Shifting, or ameliorated by resilience factors that promote positive social interactions and self-care (emotional support, religious service attendance, self-compassion). An exploratory Aim will also examine linkages between Shifting, sleep disturbance, and CHD risk.

项目概要非裔美国女性冠心病 (CHD) 相关死亡率高得惊人与所有其他种族/族裔群体的妇女相比，这种过度负担已经持续了数十年，新的证据表明，睡眠障碍在年轻至中年女性中呈上升趋势。（例如，睡眠时间短、睡眠连续性差）可能是非裔美国人患冠心病风险的重要驱动因素然而，因为大多数关于非裔美国女性睡眠障碍的研究都集中在女性身上。与其他种族/族裔群体的女性相比，对因素的了解存在巨大差距可能会促进和预防非裔美国女性的睡眠障碍。对于制定有针对性的干预措施以改善睡眠并最终减少冠心病至关重要拟议的项目旨在研究是否以及如何“转变”——一种新颖的、研究发现非洲裔美国女性中突出的社会文化现象可能会影响睡眠这一群体中的骚乱被定义为非裔美国人的一种看似适应性的做法。女性进行自我改变行为，以适应主流社会并适应非洲人的需求。尽管有关于非裔美国人的定性研究和轶事记载。过去30年女性的经历，对转变的实证研究最近才出现，并且没有一个关注健康问题。我们有关于中年非洲裔美国人的令人信服的初步数据。女性，表明有关转变的报告（例如，改变言语模式、淡化成就、自我改变）沉默）与主观睡眠障碍和体重指数（BMI）相关，但不能解释为根据这些初步数据，我们将消除抑郁情绪、歧视性压力或其他慢性压力。检查日常心理过程和睡眠之间的预期相互关系 400 名年龄在 35 岁至 54 岁之间、来自不同 SES 背景的非裔美国女性受到了困扰。睡眠质量将通过主观验证的问卷进行测量，睡眠持续时间和连续性将在基线的 14 天内通过体动记录仪进行评估，以便阐明时间性，在 12 个月的随访中，以便让我们更深入地了解如何转变。可能会导致每晚的睡眠障碍、日复一日的压力、负面情绪和警觉性将通过日记进行评估，同时进行 14 天的体动记录评估。最后，我们将检查我们的冒险关系是否会因社会经济地位而恶化（SES），这可能会增加转变的可能性，或者通过促进积极的弹性因素来改善社交互动和自我护理（情感支持、参加宗教仪式、自我同情）。探索性目标还将研究转移、睡眠障碍和冠心病风险之间的联系。
