■平均而言,被种族化为非西班牙裔黑人的成年人和西班牙裔比被种族化为非西班牙裔白人的成年人睡眠更差(以下,黑色,西班牙裔,白色),但是在这些群体中可能缓和睡眠记忆关联的因素之间的关联,例如邻里条件,不清楚。较差的邻域条件(例如,较低的邻域内聚力)可能与睡眠质量负相关,并且成倍地影响睡眠-记忆关联。我们假设较低的邻域条件评级将与较差的睡眠质量和适度的睡眠质量和情景记忆之间的关联有关。尤其是黑人和西班牙裔成年人,他们不成比例地位于恶劣的社区条件下。
■从曼哈顿北部社区招募了成年寿命(27-89岁)的7136名成年人,作为种族和种族差异后代研究的一部分阿尔茨海默病。使用匹兹堡睡眠质量指数的修订版评估睡眠质量。并通过Buschke选择性提醒测试评估了情景记忆。使用多元回归模型,我们在按种族/族裔和性别认同组分层的情景记忆中测量了感知的邻里状况与睡眠质量之间的关联以及睡眠质量与邻里状况之间的相互作用.
■总的来说,较差的邻里条件与较差的睡眠质量相关.在黑人和西班牙裔女性中,睡眠-记忆关联受邻里条件调节.有了更有利的邻里条件,黑人女性表现出更高的睡眠质量和更高的记忆表现之间的关联,和西班牙裔女性显示出邻里的保护作用(即使睡眠质量差,记忆力也更高)。
■较差的邻里体验可能会导致各组睡眠质量较差。在黑人和西班牙裔女性中,睡眠质量和情景记忆表现之间的关联取决于邻里条件。这些发现可能会告诉我们,结构层面的睡眠干预,旨在改善邻里体验,从而改善睡眠质量和情景记忆。
UNASSIGNED: On average, adults racialized as non-Hispanic Black and Hispanic sleep more poorly than adults racialized as non-Hispanic White (hereafter, Black, Hispanic, White), but associations between factors that may moderate sleep-memory associations in these groups, such as neighborhood conditions, are unclear. Poorer
neighborhood conditions (e.g. lower
neighborhood cohesion) may be negatively associated with sleep quality and multiplicatively influence sleep-memory associations. We hypothesized lower ratings of
neighborhood conditions would be associated with poorer sleep quality and moderate the association between sleep quality and episodic memory, especially in Black and Hispanic adults, who are disproportionately situated in poor neighborhood conditions.
UNASSIGNED: Seven-hundred-thirty-six adults across the adult lifespan (27-89 years) were recruited from the northern Manhattan community as a part of the Offspring Study of Racial and Ethnic Disparities in Alzheimer\'s disease. Sleep quality was assessed using a modified version of the Pittsburgh Sleep Quality Index, and episodic memory was evaluated with the Buschke Selective Reminding Test. With multiple regression models, we measured associations between perceived neighborhood conditions and sleep quality and the interaction between sleep quality and neighborhood conditions on episodic memory stratified by racial/ethnic and gender identity groups.
UNASSIGNED: Overall, poorer neighborhood conditions were associated with poorer sleep quality. In Black and Hispanic women, the sleep-memory association was moderated by
neighborhood conditions. With more favorable neighborhood conditions, Black women showed an association between higher sleep quality and higher memory performance, and Hispanic women showed a protective effect of
neighborhood (higher memory even when sleep quality was poor).
UNASSIGNED: Poorer
neighborhood experiences may contribute to poorer sleep quality across groups. In Black and Hispanic women, the association between sleep quality and episodic memory performance was dependent upon neighborhood conditions. These findings may inform tailored, structural level sleep interventions, aimed to improve neighborhood experiences and thereby sleep quality and episodic memory.
