: College students are at increased risk for sleep disorders, including insomnia disorder and obtaining less than 6.5 hr of sleep per night by choice, or behaviorally induced insufficient sleep syndrome (BIISS). These disorders can have deleterious daytime consequences, including depression. This study aims to establish the prevalence of insomnia and BIISS disorders and examine associations of insomnia and BIISS with other sleep characteristics and depression. : A subset of data from Spit for Science, a college risk behaviors and health study ( = 989) was used. Insomnia and BIISS were defined as mutually exclusive disorders, based on diagnostic criteria. : A majority (68%) of students were categorized as normal sleepers, followed by insomnia (22%), and BIISS (10%). Sleep duration was comparable between BIISS and insomnia, while daytime sleepiness was significantly higher in BIISS, and sleep latency was longer in insomnia ( = 44 vs. = 13 min). Insomnia was associated with the highest depression symptoms, followed by BIISS, and normal sleep, controlling for demographics. Insomnia was associated with twice the risk of moderate or higher depression compared to normal sleep (CI: 1.60, 2.70, < .001). : These findings highlight the sleep difficulties endemic to college populations. Further, this study provides the first prevalence estimation of BIISS in college students and the first comparison of insomnia and BIISS on sleep characteristics and depressive symptoms. This study underscores the importance of targeted screening and intervention to improve both sleep and depression in this vulnerable population.
: 大学生患睡眠障碍的风险增加，包括失眠症和每晚选择睡眠不足 6.5 小时，或行为性诱导的睡眠不足综合征（BIISS）。这些疾病会导致白天出现不良后果，包括抑郁。本研究旨在确定失眠和 BIISS 障碍的患病率，并检查失眠和 BIISS 与其他睡眠特征和抑郁之间的关联。 : 利用 Spit for Science 大学风险行为和健康研究的数据子集（= 989）。根据诊断标准，将失眠和 BIISS 定义为相互排斥的疾病。 : 大多数学生（68%）被归类为正常睡眠者，其次是失眠（22%）和 BIISS（10%）。BIISS 和失眠的睡眠时间相当，而 BIISS 的白天嗜睡明显更高，失眠的睡眠潜伏期更长（= 44 分钟 vs. = 13 分钟）。控制人口统计学因素后，失眠与最高的抑郁症状相关，其次是 BIISS 和正常睡眠。与正常睡眠相比，失眠与中度或更高程度的抑郁相关的风险增加了两倍（CI：1.60，2.70，<0.001）。 : 这些发现强调了大学生群体中普遍存在的睡眠困难。此外，本研究首次对大学生 BIISS 的患病率进行了估计，并且首次比较了失眠和 BIISS 在睡眠特征和抑郁症状方面的差异。本研究强调了针对这一弱势群体进行有针对性的筛查和干预以改善睡眠和抑郁的重要性。
