This study aimed to evaluate the sleep quality and the Social Jetlag frequency in young adults during social distancing because of COVID-19. This is a cross-sectional study with 308 students aged ≥18 years and with Internet access. Questionnaires used: Pittsburgh Sleep Quality Index - Brazil (PSQI-BR), Epworth Sleepiness Scale, and Munich Chronotype Questionnaire. The mean age of the students was 21 ± 3 years (17 - 42y), with no statistically significant difference between genders. The PSQI-BR indicated that 257 (83.4%) had poor sleep quality. The mean of Social Jetlag for young adults was 02:00 ± 01:49h, and we observed that 16.6% (n = 51) had Social Jetlag. Compared to men in the good sleep quality group, women had higher means for sleep duration on study days and free days, mid-point of sleep on study days and free days and corrected mid-point of sleep on free days. However, when compared to men in the group of poor sleep quality, we observed higher means for women regarding sleep duration on study days, the mid-point of sleep on study days, and the corrected mid-point of sleep on free days. Thus, the high frequency of young adult students who had poor sleep quality associated with Social Jetlag (2 hours) in the present study may reflect a pattern of sleep irregularity, which may be associated with impairment of environmental synchronizers and stimulation of social synchronizers during the lockdown resulting from the COVID-19 pandemic.
本研究旨在评估因新冠疫情实施社交隔离期间年轻成年人的睡眠质量和社会时差频率。 这是一项横断面研究，共有308名年龄≥18岁且能上网的学生参与。使用的问卷包括：匹兹堡睡眠质量指数 - 巴西版（PSQI - BR）、爱泼华嗜睡量表和慕尼黑昼夜节律问卷。 学生的平均年龄为21±3岁（17 - 42岁），性别之间无统计学显著差异。PSQI - BR表明，257名（83.4%）学生睡眠质量较差。年轻成年人的社会时差平均为02:00±01:49小时，我们观察到16.6%（n = 51）的人存在社会时差。与睡眠质量良好组的男性相比，女性在学习日和休息日的睡眠时间均值、学习日和休息日的睡眠中点以及休息日的校正睡眠中点更高。然而，与睡眠质量较差组的男性相比，我们观察到女性在学习日的睡眠时间均值、学习日的睡眠中点以及休息日的校正睡眠中点更高。 因此，本研究中睡眠质量差且伴有社会时差（2小时）的年轻成年学生的高频率情况可能反映了一种睡眠不规律模式，这可能与新冠疫情封锁期间环境同步器受损和社会同步器受到刺激有关。
