Due to the demanding nature of their profession, nurses are at risk of experiencing irregular sleep patterns, substance use, and fatigue. Evidence supports a reciprocal relationship between alcohol use and sleep disturbances; however, no research has examined such a link in a sample of nurses. One factor that may further impact the dynamic between alcohol and sleep patterns is posttraumatic stress disorder (PTSD) symptoms. We investigated the daily bidirectional associations between alcohol use and several sleep domains (i.e., self-report and actigraphy-determined sleep), and moderation by baseline PTSD symptom severity.
Over a 14-day period, 392 nurses (92% female; 78% White) completed sleep diaries and actigraphy to assess alcohol use and sleep patterns. Within-person bidirectional associations between alcohol and sleep were examined using multilevel models, with symptoms of PTSD as a cross-level moderator.
Daily alcohol use (i.e., ≥ 1 alcoholic beverage; 25.76%) was associated with shorter self-reported sleep onset latency (b = -4.21, p = .003) but longer self-reported wake after sleep onset (b = 2.36, p = .009). Additionally, days with any alcohol use were associated with longer self-reported sleep duration (b = 15.60, p = .006) and actigraphy-determined sleep duration (b = 10.06, p = .037). No sleep variables were associated with next-day alcohol use. Bidirectional associations between alcohol consumption and sleep were similar regardless of baseline PTSD symptoms.
Our results suggested that on days when nurses drank alcohol, they experienced longer but also more fragmented sleep.
由于职业要求苛刻，护士存在睡眠模式不规律、使用药物和疲劳的风险。有证据支持饮酒与睡眠障碍之间存在相互关系；然而，尚无研究在护士样本中考察这种联系。创伤后应激障碍（PTSD）症状可能是进一步影响酒精与睡眠模式之间动态关系的一个因素。我们调查了饮酒与几个睡眠领域（即自我报告和通过活动记录仪确定的睡眠）之间的每日双向关联，以及基线PTSD症状严重程度的调节作用。
在14天的时间里，392名护士（92%为女性；78%为白人）完成了睡眠日记和活动记录仪监测，以评估饮酒情况和睡眠模式。使用多层次模型检验酒精与睡眠之间的个体内双向关联，将PTSD症状作为跨层次调节因素。
每日饮酒（即≥1杯酒精饮料；25.76%）与自我报告的睡眠起始潜伏期缩短（b=-4.21，p=0.003）相关，但与自我报告的睡眠中觉醒时间延长（b=2.36，p=0.009）相关。此外，饮酒的日子与自我报告的睡眠时间延长（b=15.60，p=0.006）和通过活动记录仪确定的睡眠时间延长（b=10.06，p=0.037）相关。没有睡眠变量与次日饮酒相关。无论基线PTSD症状如何，饮酒与睡眠之间的双向关联相似。
我们的结果表明，护士饮酒的日子里，他们的睡眠时间更长但也更碎片化。
