研究目的：邻里劣势与睡眠不佳有关。然而，现有的研究主要集中在自我报告的睡眠和邻里特征的评估。目前的研究探讨客观和感知的邻里特征和活动记录评估的睡眠持续时间，效率和觉醒后的睡眠onset（WASO）在城市样本的African American adults.Methods：我们研究了数据，主要来自非洲裔美国成年人（n = 788，平均年龄55岁，77%的女性）生活在两个低收入社区。感知的邻里特征包括安全性，社会凝聚力和满意度与一个人的邻居作为一个居住的地方。客观的邻里条件包括步行能力，混乱，街道照明和犯罪水平。睡眠持续时间，效率，和WASO通过7天的腕戴式体动仪测量。分析估计每一个睡眠结果作为感知和客观的邻居特征的函数。个人层面的社会人口统计学，身体质量指数，心理困扰包括作为covariates.Results：更大的感知安全与更高的睡眠效率和更短的WASO。更大的邻里关系紊乱和街道照明与更差的睡眠效率和更长的WASO以及更大的睡眠时间短的可能性相关（< 7小时与7-9小时作为参考）。更高水平的犯罪与睡眠效率差，更长的WASO，但这些协会只在一个明显的neighborhoods.Conclusions：无论是居民如何看待他们的邻居和他们的接触到客观测量的邻里混乱，照明，和犯罪的影响睡眠的连续性。这些发现表明，邻里条件可能导致睡眠健康的差异。
Study Objectives: Neighborhood disadvantage has been linked to poor sleep. However, the extant research has primarily focused on self-reported assessments of sleep and neighborhood characteristics. The current study examines the association between objective and perceived neighborhood characteristics and actigraphy-assessed sleep duration, efficiency, and wakefulness after sleep onset (WASO) in an urban sample of African American adults.Methods: We examined data from predominantly African American adults (n = 788, mean age 55 years; 77% female) living in two low-income neighborhoods. Perceived neighborhood characteristics included safety, social cohesion, and satisfaction with one's neighborhood as a place to live. Objective neighborhood conditions included walkability, disorder, street lighting, and crime levels. Sleep duration, efficiency, and WASO were measured via 7 days of wrist-worn actigraphy. Analyses estimated each of the sleep outcomes as a function of perceived and objective neighborhood characteristics. Individual-level sociodemographics, body mass index, and psychological distress were included as covariates.Results: Greater perceived safety was associated with higher sleep efficiency and shorter WASO. Greater neighborhood disorder and street lighting were associated with poorer sleep efficiency and longer WASO and greater likelihood of short sleep duration (< 7 versus 7-9 hr as referent). Higher levels of crime were associated with poorer sleep efficiency and longer WASO, but these associations were only evident in one of the neighborhoods.Conclusions: Both how residents perceive their neighborhood and their exposure to objectively measured neighborhood disorder, lighting, and crime have implications for sleep continuity. These findings suggest that neighborhood conditions may contribute to disparities in sleep health.
