To investigate the sleep status of college and high schools students.
Pittsburgh sleep quality index (PSQI) and self-manufactured questionnaires about siesta habits were used as tools. Three groups of students from medical college (MC), senior high school (SS) and junior high school (JS) were surveyed.
In the group MC, SS and JS, the occurrence rates of sleep disorders were 27%, 62% and 54%, respectively, and in which the appearance rates of insomnia were 17%, 19% and 19%, longing for sleep were 10%, 43% and 35% respectively. And there were no significant difference between schoolboy and schoolgirl. The occurrence rates of slack breathing were different (5/155, 1/154) significantly between group SS and JS. The distinct differences also were found in group JS and MC, in which students felt hot (10/155, 1/122) and in all the three groups, in which students felt sleepy (55/155, 62/154, 13/122) whereas the difference of sleepy between group SS and JS was comparatively distinct (55/155, 62/154). Significant differences were also found between group JS and SS, MC in average sleep time of (7.65 +/- 0.87) hours, (7.16 +/- 0.83) hours, and (7.10 +/- 0.57) hours. The time of falling asleep (median 15 min, 10 min, 20 min) and siesta habit (8/155, 19/154, 75/122) among group MC and SS, JS were different respectively and markedly, whereas siesta habit differences between group SS and JS were comparatively distinct (8/155, 19/154).
Students in high school showed higher rate of longing for sleep, and this implicated they fall short of sleep time greatly and siesta could improve their sleepy signs.
调查大、中学生的睡眠状况。
采用匹兹堡睡眠质量指数（PSQI）和自制的午睡习惯问卷作为工具，对医学院学生（MC）、高中生（SS）和初中生（JS）三组学生进行调查。
在MC组、SS组和JS组中，睡眠障碍发生率分别为27%、62%和54%，其中失眠发生率分别为17%、19%和19%，渴望睡眠发生率分别为10%、43%和35%。男女生之间无显著差异。SS组和JS组之间呼吸不畅发生率差异显著（5/155，1/154）。JS组和MC组之间也存在明显差异，其中学生感觉热（10/155，1/122），三组学生均存在困倦感（55/155，62/154，13/122），而SS组和JS组之间的困倦差异较为明显（55/155，62/154）。JS组与SS组、MC组的平均睡眠时间（分别为7.65±0.87小时、7.16±0.83小时和7.10±0.57小时）也存在显著差异。MC组与SS组、JS组之间入睡时间（中位数分别为15分钟、10分钟、20分钟）和午睡习惯（8/155，19/154，75/122）分别存在显著差异，而SS组和JS组之间的午睡习惯差异较为明显（8/155，19/154）。
高中生渴望睡眠的发生率较高，这意味着他们严重缺乏睡眠时间，午睡可以改善他们的困倦症状。
