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.

项目摘要 非洲裔美国妇女的冠状动脉疾病（CHD）相关的死亡率很高 与所有其他种族/族裔的妇女相比，残疾。超过伯恩已经持续了数十年， 并且在中年妇女中正在上升。新兴证据表明睡眠障碍 （例如，睡眠时间短，睡眠连续性差）可能是非裔美国人的CHD风险的重要驱动力 女性;但是，由于大多数关于非裔美国妇女睡眠灾难的研究都集中在 与其他种族/族裔群体的妇女进行比较，有关因素的知识差距很大 这可能会促进并预防非裔美国妇女的睡眠障碍。这样的信息 对于开发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 在这个人群中的风险。拟议的项目旨在检查是否以及如何“转移” - 一部小说， 社会文化现象假设在非洲裔美国妇女中是显着的 - 可能会影响睡眠 这一组中的干扰。转移被定义为一种看似适应性的实践，非洲裔美国人 妇女从事自我改变的行为，以适应占主导地位的社会和非洲的住宿 - 美国男性。尽管在定性研究和非裔美国人的轶事中记录了 妇女在过去30年中的经历，关于转移的经验研究直到最近才出现，并且 没有人专注于健康。我们有关于早期中年非裔美国人的引人入胜的初步数据 妇女表明转移的报告（例如，语音模式变化，轻描淡写的成就，自我 沉默）与主观睡眠障碍和体重指数（BMI）有关，未解释 影响抑郁症，或歧视性或其他慢性应激源。在此初步数据的基础上，我们将 检查转移，日常心理过程和睡眠之间的潜在相互关系 来自SES背景的400名35-54岁的非裔美国妇女的骚乱。转移和 主观睡眠质量将通过经过验证的问卷来衡量，睡眠时间和连续性将 在基线的14天的过程中通过行程进行评估，以便阐明 临时性，在12个月的随访中。为了使我们对如何转移有更深入的了解 可能会在夜间到晚上造成睡眠灾难，日常压力的报告，负面影响和 在14天期间，将通过每日日记与行动摄影评估同时评估警惕性。 最后，我们将研究我们假设的关系是否因社会经济地位加剧 （SES），这可能会增加转移的可能性，或通过弹性阳性的弹性因素改善 社会互动和自我保健（情感支持，宗教服务的出席，自我同情）。一个 探索目的还将检查转移，睡眠障碍和CHD风险之间的联系。
