The aim of this study was to assess medical students' quality of sleep and excessive daytime sleepiness in different graduation cycles.
A cross-sectional study was carried out at a private university in Maceió, Brazil, from August 2021 to March 2022. The sample was composed of medical students aged 18 years and above from years 1-2 (basic cycle), 3-4 (clinical cycle), and 5-6 (internship) of Medical School who were invited to answer two validated questionnaires: the Pittsburgh Sleeping Quality Index and the Epworth Sleepiness Scale.
A total of 179 students participated; most of them were female (78.2%), aged 19-25 years (73.7%), and with a body mass index<25 kg/m2 (73.7%), with smaller participation from students from the basic cycle (21.2%). Analyzing the Pittsburgh Sleeping Quality Index, 55.9% of the students were classified as having poor sleep quality, with no difference in sleep category between gender, age, body mass index, and graduation cycle. Students with a body mass index of ≥25 kg/m2 had longer sleep latency (p=0.016) and shorter sleep duration (p=0.027). The Epworth Sleepiness Scale assessment showed that 44.1% of the students exhibit daytime sleepiness. Women had more daytime sleepiness than men (p=0.017), with no difference between age, body mass index, and graduation cycle.
About half of the medical students experience poor sleep quality and daytime sleepiness, regardless of the graduation cycle. This should trigger a targeted institutional intervention to promote better mental and physical health, as well as sleep hygiene, to reduce future health issues.
本研究旨在评估不同毕业阶段医学生的睡眠质量和日间过度嗜睡情况。
2021年8月至2022年3月，在巴西马塞约的一所私立大学开展了一项横断面研究。样本由医学院1 - 2年级（基础阶段）、3 - 4年级（临床阶段）和5 - 6年级（实习阶段）18岁及以上的医学生组成，他们被邀请回答两份经过验证的问卷：匹兹堡睡眠质量指数问卷和爱泼华嗜睡量表。
共有179名学生参与；其中大多数为女性（78.2%），年龄在19 - 25岁之间（73.7%），体重指数<25 kg/m²（73.7%），基础阶段的学生参与度较低（21.2%）。分析匹兹堡睡眠质量指数发现，55.9%的学生被归类为睡眠质量差，在性别、年龄、体重指数和毕业阶段之间的睡眠类别上没有差异。体重指数≥25 kg/m²的学生睡眠潜伏期更长（p = 0.016），睡眠时间更短（p = 0.027）。爱泼华嗜睡量表评估显示，44.1%的学生存在日间嗜睡。女性的日间嗜睡情况比男性更严重（p = 0.017），在年龄、体重指数和毕业阶段之间没有差异。
无论毕业阶段如何，约一半的医学生存在睡眠质量差和日间嗜睡的情况。这应引发有针对性的机构干预，以促进更好的身心健康以及睡眠卫生，减少未来的健康问题。
