Abstract
Objective: We investigated the relationship between irregular sleep-wake patterns and other aspects of sleep and mental health among adolescents.
Methods: Community-based sample of adolescents (n = 200, mean age 16.8; 61.7% female) completed baseline assessment (i.e. sleep quality, daytime sleepiness, depressive symptoms, social anhedonia, problematic alcohol use), and 7-8 consecutive days of wearing wrist actigraphy. Irregular sleep-wake patterns were assessed via two methods, both based on actigraphy, to capture day-to-day irregularity (intraindividual variability, IIV) and weekly irregularity (social jet lag, SJL). The Bayesian variability method was performed to calculate IIV in total sleep time (TST), sleep onset, and offset time. SJL was quantified as the actual difference in the sleep midpoint on school days versus non-school days.
Results: Greater IIV in TST was associated with poorer sleep quality (B = 1.66, 95% CI, 0.14, 3.31, p < .05), and greater depressive symptoms (B = 0.72, 95% CI, 0.17, 1.35, p < .05), while greater IIV in sleep offset time was associated greater depressive symptoms (B = 0.63, 95% CI, 0.03, 1.28, p < .05), and greater problematic alcohol use (B = 0.70, 95% CI, 0.12, 1.35, p < .05), all after adjusting for age, sex, family SES, alcohol drinks, and SJL. No significant association was found with sleep onset time. Greater SJL was associated with poorer sleep quality (B = 0.40, 95% CI, 0.27, 0.54, p < .001) and fewer problematic alcohol uses (B = -0.05, 95% CI, -0.09, -0.00, p < .05), when adjusting for age, sex, family SES, and alcohol drinks.
Conclusion: Our findings add to a growing body of research on irregularity in sleep-wake patterns and clinical implications.
目的：我们调查了青少年不规律的睡眠-觉醒模式与其他方面的睡眠和心理健康之间的关系：我们调查了青少年不规律的睡眠-觉醒模式与睡眠和心理健康的其他方面之间的关系：基于社区的青少年样本（n = 200，平均年龄 16.8 岁；61.7% 为女性）完成了基线评估（即睡眠质量、白天嗜睡、抑郁症状、社交消沉、问题性饮酒），并连续 7-8 天佩戴腕部动电仪。不规则的睡眠-觉醒模式是通过两种方法进行评估的，这两种方法都是基于腕动仪，以捕捉每天的不规则性（个体内变异性，IIV）和每周的不规则性（社交时差，SJL）。贝叶斯变异性方法用于计算总睡眠时间（TST）、睡眠开始时间和偏移时间的个体内变异性。SJL 被量化为上学日与非上学日睡眠中点的实际差异：结果：TST 的 IIV 值越大，睡眠质量越差（B = 1.66，95% CI，0.14, 3.31，p p p p p p 结论：我们的发现为越来越多的研究提供了新的依据：我们的研究结果为越来越多关于睡眠-觉醒模式不规律及其临床影响的研究增添了新的内容。
期刊介绍：
Behavioral Sleep Medicine addresses behavioral dimensions of normal and abnormal sleep mechanisms and the prevention, assessment, and treatment of sleep disorders and associated behavioral and emotional problems. Standards for interventions acceptable to this journal are guided by established principles of behavior change. Intending to serve as the intellectual home for the application of behavioral/cognitive science to the study of normal and disordered sleep, the journal paints a broad stroke across the behavioral sleep medicine landscape. Its content includes scholarly investigation of such areas as normal sleep experience, insomnia, the relation of daytime functioning to sleep, parasomnias, circadian rhythm disorders, treatment adherence, pediatrics, and geriatrics. Multidisciplinary approaches are particularly welcome. The journal’ domain encompasses human basic, applied, and clinical outcome research. Behavioral Sleep Medicine also embraces methodological diversity, spanning innovative case studies, quasi-experimentation, randomized trials, epidemiology, and critical reviews.
