Good sleep is essential to good health. Good sleep strengthens cognitive capacities, such as memory and learning, and reduces the likelihood of making mistakes [1,2]. For these reasons, the sleeping habits of medical students are important to understand. In this issue of Academic Psychiatry, three valuable empirical papers spontaneously submitted to the journal address this neglected topic in undergraduate medical education. Two studies were conducted at individual medical schools on the two US coasts and the other study involved 860 medical students from 49 different US medical colleges. Taken together, this unique set of data-based papers tells us a great deal about the current state of sleep among our early career colleagues.
Sleep Behaviors of Medical StudentsAhmed et al.[3] performed a cross-sectional study of medical students at SUNY Downstate Medical School (n = 261). The authors found that, on average, more than 70% of students felt they needed 7 h of sleep each night; however, only one quarter of students slept an average of 7 h nightly. Most students slept considerably fewer hours routinely, and during the week of an examination, only 15% of preclinical students and 19% of clinical students had more than 7 h of sleep [3]. Clinical students had considerably more sleepiness than preclinical students and clinical students were also more knowledgeable about the topic of sleep. Preclinical and clinical students held similar views about sleep, as measured by the Dysfunctional Beliefs and Attitudes about Sleep (DBAS) scale [3]. This study also examined whether students used prescription sleep medication, over-the-counter sleeping pills, or behavioral sleep strategies. Most students reported that they "never" used prescription medications (80%) or over-the-counter sleeping pills (67%), while a small number reported using these methods "often/daily" (2%, 7%, respectively). Behavioral strategies were endorsed more commonly, with 13% using these approaches "often/daily" and 14% using them "occasionally/monthly." Overall, clinical students were more likely than preclinical students to use prescription medication, overthe-counter sleeping pills, and behavioral strategies.In their cross-sectional online survey of medical students (n = 860) across 49 medical schools in 29 states, Ayala et al.[4] similarly found that students slept less than 7 h each night (6.83 h, on average over the prior 4 weeks), with students receiving the least sleep in year 3 and the most sleep in year 2 of medical school. Students in their last year had fewer sleep problems, as measured by the Sleep Problems Index, which is a subset of items from the well-validated Medical Outcomes Sleep Study Scale.A vital and unique focus of the analyses in Ayala et al.'s study [4] related to the diminished quality of sleep of minority students. Minority students, defined as non-Caucasian, had more somnolence, which is reflective of daytime sleepiness, as well as lower self-reported levels of sleep adequacy and fewer hours of sleep per night.
