Assessed sleep patterns, sleep disruptions, and sleepiness of second-, fourth-, and sixth-graders. Found that older children had more delayed sleep onset times and increased reported daytime sleepiness than younger; girls spent more time in sleep than boys and had increased percentage of motionless sleep; and 18 percent of children had fragmented sleep.
