Background

Previous studies examining associations between sleep and alcohol use have done so primarily at the aggregate (between-person) level and primarily among healthy young adults. This study aimed to examine reciprocal, within-person associations between sleep and alcohol use among young adult drinkers with insomnia.

Methods

Young adults who engaged in past-month binge drinking and met diagnostic criteria for insomnia (N = 56) wore wrist actigraphy and completed online daily diaries assessing sleep and drinking for an average of 8.52 days (SD = 2.31), resulting in 477 reports. Multilevel models were used to examine within- and between-person effects of sleep quality and efficiency on alcohol use and vice versa. Bedtime and waketime were included as secondary sleep parameters.

Results

Participants reported drinking on 231 days (48%). Participants did not report significantly different sleep quality on heavier-drinking days, nor did they demonstrate significant changes in actigraphy-measured sleep efficiency. However, they self-reported better sleep efficiency on heavier-drinking days (driven primarily by improvements in sleep onset latency), and they reported heavier drinking following days of better sleep efficiency (driven by improvements in total sleep time). Drinking was also associated with later bedtimes and waketimes.

Conclusions

Young adult drinkers with insomnia report reciprocal associations between subjective sleep efficiency and alcohol use, but these results were not replicated using objective measures. Providers may need to challenge the belief that there is a positive association between alcohol use and sleep among young adults who drink and have insomnia.

患有失眠症的年轻成年饮酒者的睡眠和酒精使用：日常过程模型

背景

先前研究睡眠与饮酒之间的关联主要是在总体（人与人之间）水平上进行的，并且主要是在健康的年轻人中进行的。本研究旨在检查患有失眠症的年轻成年饮酒者的睡眠和酒精使用之间的相互关联的人际关联。

方法

过去一个月酗酒并符合失眠诊断标准的年轻人（N  = 56）佩戴手腕活动记录仪并完成在线日常日记评估睡眠和饮酒平均 8.52 天（SD  = 2.31），产生 477 份报告。多层次模型被用来检查睡眠质量和效率对酒精使用的影响，反之亦然。就寝时间和起床时间被列为次要睡眠参数。

结果

参与者报告饮酒 231 天 (48%)。参与者没有报告在大量饮酒的日子里睡眠质量有显着差异，他们也没有表现出活动记录仪测量的睡眠效率的显着变化。然而，他们自我报告在大量饮酒的日子里睡眠效率更高（主要是由于入睡潜伏期的改善），并且他们报告说在睡眠效率提高的日子里饮酒量更大（由于总睡眠时间的改善）。饮酒也与后来的就寝时间和起床时间有关。

结论

患有失眠症的年轻成年饮酒者报告了主观睡眠效率与酒精使用之间的相互关联，但这些结果并未使用客观测量方法进行复制。提供者可能需要挑战这样的信念，即饮酒和失眠的年轻人饮酒与睡眠之间存在正相关关系。
