目的：本研究的目的是检查青少年样本中对社区暴力的关注与客观和主观睡眠参数之间的联系。性被认为是影响的调节者。设计：本研究采用横断面设计。参与者：以社区为基础的样本包括252名青少年（53%鳃），平均年龄为15.79岁（SD 0.81），来自美国东南部。样本包括34%的非洲裔美国青少年和66%的欧洲裔美国青少年，他们来自不同的社会经济背景。测量方法：青少年报告的社区暴力问题使用3个独立子量表的组合来评估，这些子量表测量了感知的社区安全以及社区和学校暴力的威胁。用活动描记法评估睡眠时间和质量，用《学校睡眠习惯调查》的子量表测量主观睡眠问题和白天嗜睡。结果：社区暴力预示着较低的睡眠效率，更多的长时间清醒发作，更多的睡眠/觉醒问题和困倦。与性相关的调节效应显示，样本中的女孩更容易受到暴力对其客观睡眠质量的影响。结论：研究结果强调了社区暴力对青少年睡眠的影响，揭示了更大的社区暴力关注与更低水平的基于活动记录和主观睡眠质量报告有关，特别是对青春期女孩而言。讨论了暴力问题可能影响睡眠的机制。(C) 2016年国家睡眠基金会。Elsevier Inc.出版。版权所有。
Objective: The goal of this study was to examine links between concerns about community violence and objective and subjective sleep parameters in an adolescent sample. Sex was considered as a moderator of effects.Design: The study used a cross-sectional design.Participants: The community-based sample included 252 adolescents (53% gills) with an average age of 15.79 years (SD 0.81) from the Southeastern United States. The sample included 34% African American and 66% European American adolescents from a wide range of socioeconomic backgrounds.Measurements: Adolescent-reported community violence concerns were assessed using a composite of 3 separate subscales that measured perceived community safety and threats of community and school violence. Sleep duration and quality were assessed using actigraphy, and subjective sleep problems and daytime sleepiness were measured with subscales of the School Sleep Habits Survey.Results: Community violence predicted lower sleep efficiency, more long-wake episodes, and more sleep/wake problems and sleepiness. Sex-related moderation effects revealed that girls in the sample were more vulnerable to the effects of violence concerns on their objective sleep quality.Conclusions: Findings highlight the role of community violence concerns on adolescents' sleep, revealing that greater community violence concerns are linked with lower levels of actigraphy-based and subjective reports of sleep quality, particularly for adolescent girls. Consideration of the mechanisms by which violence concerns may affect sleep is discussed. (C) 2016 National Sleep Foundation. Published by Elsevier Inc. All rights reserved.
