摘要：

Five hundred and twelve students aged from 6 to 18 years were administered the morningness-eveningness questionnaire and a sleep log. The mean morningness-eveningness score decreased with grade; this decrease was significant around the seventh grade. The habitual waking time Showed nd difference among grades but the habitual bedtime became later with grade; thus, the sleep length on weekdays decreased with grade. The percentage of students falling asleep during school lessons significantly increased from the eighth to 12th grade. We found that a delay of Sleep phase, reduction of sleep length, increased daytime sleep, and transition to evening type occurred at around the seventh grade.
