Abstract

The prevalence rate of falling asleep while watching TV before 8 P.M.

The prevalence rate of falling asleep while doing home work, falling sleep during a lesson, snoring and bruxism were 12.6%, 1.0%, 26.7% and 13.2% respectively. Although these rates did not show any differences between grades, snoring as more in boys and daytime fatigue was more in girls.
