Although psychostimulants have been shown to affect sleep in experimental studies, the relation between nonmedical psychostimulant use and sleep has not been examined. Our goal was to describe the sleep quality and characteristics of college students who use psychostimulant medications nonmedically.
We surveyed 492 college students about their sleep quality and psychostimulant use characteristics. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI); psychostimulant use and characteristics were measured via a survey developed for this study.
College students who self-reported current or a history of nonmedical psychostimulant use reported worse subjective sleep quality, sleep disturbance, and global PSQI scores than nonusers. The most commonly reported reason for nonmedical psychostimulant use was to improve work performance and concentration.
These data demonstrate worse sleep quality among nonmedical psychostimulant users. The likely consequence of increased daytime sleepiness helps to confirm the known public health concern of nonmedical prescription psychostimulant use among college students.
虽然有实验研究表明，精神兴奋剂会影响睡眠，但非医疗用途的精神兴奋剂使用与睡眠之间的关系尚未得到检验。我们的目的是描述非医疗使用精神兴奋剂药物的大学生的睡眠质量和特征。
我们调查了 492 名大学生的睡眠质量和精神兴奋剂使用特征。使用匹兹堡睡眠质量指数（PSQI）评估睡眠质量；通过为这项研究开发的调查来衡量精神兴奋剂的使用和特征。
自我报告当前或过去非医疗使用精神兴奋剂的大学生报告的主观睡眠质量、睡眠障碍和整体 PSQI 评分均差于非使用者。最常报告的非医疗使用精神兴奋剂的原因是提高工作表现和注意力。
这些数据表明，非医疗使用精神兴奋剂者的睡眠质量更差。白天嗜睡的可能性后果有助于证实公众对大学生非医疗处方精神兴奋剂使用的已知健康问题的关注。
