Low socioeconomic status (SES) has been associated with poor sleep in youth, yet mechanisms underlying this association are not well-understood. The present study examined greater chaos as a mediator of associations between low SES and 2 indices of poor sleep. Two hundred fifty-two adolescents (53% girls; 66% White/European American, 34% Black/African American) participated in the 3-wave longitudinal study. The sample was socioeconomically diverse. At age 16, parents reported on 2 indices of SES: family income and perceived economic well-being. Adolescents reported on chaos within their family at age 17 and on 2 key sleep-wake processes-sleep quality and daytime sleepiness-at age 18. Family chaos functioned as a mediating or intervening variable in longitudinal associations between lower SES and both poorer sleep quality and greater daytime sleepiness. The findings suggest the potential utility of targeting family level processes that exemplify chaos, such as unpredictability, noise, and interruptions, to improve sleep among adolescents.

青春期的社会经济地位和睡眠：家庭混乱的作用。


低社会经济地位（SES）与青少年睡眠质量差有关，但这种关联背后的机制尚不清楚。本研究考察了更大的混乱作为低 SES 与 2 个睡眠不佳指数之间关联的中介因素。 252 名青少年（53% 为女孩；66% 为白人/欧洲裔美国人，34% 为黑人/非裔美国人）参与了 3 波纵向研究。样本在社会经济方面具有多样性。 16 岁时，父母报告了 SES 的 2 个指数：家庭收入和感知的经济福祉。青少年在 17 岁时报告了家庭内部的混乱情况，并在 18 岁时报告了两个关键的睡眠-觉醒过程——睡眠质量和白天嗜睡。家庭混乱在较低 SES 与较差的睡眠质量和睡眠质量之间的纵向关联中发挥了中介或干预变量的作用。白天更加困倦。研究结果表明，针对家庭层面的流程（例如不可预测性、噪音和干扰）来改善青少年的睡眠具有潜在的效用。 （PsycINFO 数据库记录 (c) 2020 APA，保留所有权利）。
