Study Objectives In an older African-American sample (n = 231) we tested associations of the household environment and in-bed behaviors with sleep duration, efficiency, and wakefulness after sleep onset (WASO). Methods Older adult participants completed a household-level sleep environment questionnaire, a sleep questionnaire, and underwent 7-day wrist actigraphy for objective measures of sleep. Perceived household environment (self-reported) was evaluated using questions regarding safety, physical comfort, temperature, noise, and light disturbances. In-bed behaviors included watching television, listening to radio/music, use of computer/tablet/phone, playing video games, reading books, and eating. To estimate the combined effect of the components in each domain (perceived household environment and in-bed behaviors), we calculated and standardized a weighted score per sleep outcome (e.g. duration, efficiency, WASO), with a higher score indicating worse conditions. The weights were derived from the coefficients of each component estimated from linear regression models predicting each sleep outcome while adjusting for covariates. Results A standard deviation increase in an adverse household environment score was associated with lower self-reported sleep duration (β = −13.9 min, 95% confidence interval: −26.1, −1.7) and actigraphy-based sleep efficiency (β = −0.7%, −1.4, 0.0). A standard deviation increase in the in-bed behaviors score was associated with lower actigraphy-based sleep duration (β = −9.7 min, −18.0, −1.3), sleep efficiency (β = −1.2%, −1.9, −0.6), and higher WASO (5.3 min, 2.1, 8.6). Conclusion Intervening on the sleep environment, including healthy sleep practices, may improve sleep duration and continuity among African-Americans.

感知的家庭睡眠环境:杰克逊心脏睡眠研究中家庭因素和床上行为与基于活动记录的睡眠持续时间和连续性的关联

研究目标 在一个年长的非裔美国人样本 (n = 231) 中,我们测试了家庭环境和床上行为与睡眠持续时间、效率和入睡后觉醒 (WASO) 之间的关联。方法 老年参与者完成家庭级睡眠环境问卷、睡眠问卷,并接受为期 7 天的腕部活动记录仪以客观测量睡眠。使用有关安全、身体舒适度、温度、噪音和光干扰的问题评估感知的家庭环境(自我报告)。在床上的行为包括看电视、听广播/音乐、使用电脑/平板电脑/电话、玩电子游戏、看书和吃东西。估计每个领域中组件的综合影响(感知的家庭环境和床上行为),我们计算并标准化了每个睡眠结果(例如持续时间、效率、WASO)的加权分数,分数越高表示条件越差。权重来源于每个组件的系数,这些系数是根据线性回归模型估计的,该模型预测每个睡眠结果,同时针对协变量进行调整。结果 不良家庭环境评分的标准差增加与自我报告的睡眠持续时间降低(β = -13.9 分钟,95% 置信区间:-26.1,-1.7)和基于活动记录的睡眠效率(β = -0.7%)相关, -1.4, 0.0). 床上行为得分的标准差增加与基于活动记录的睡眠持续时间(β = -9.7 分钟,-18.0,-1.3)、睡眠效率(β = -1.2%,-1.9,-0.6)、和更高的 WASO(5.3 分钟、2.1、8.6)。结论 干预睡眠环境,
