| Research Abstract |
We surveyed about 2500 preschoolers and found 70% of 3yrs, 80% of 4yrs, 90% of 5yrs, and 95% of 6yrs took no naps. Especially in 3yr old children, far more percentage (70%) of the children take no naps compared with the data (40%) of the previous study. We have to investigate this discrepancy of these two data. A municipal government of Tokyo area agreed that all the public nursery preschools in the area to stop nap routine according to our advises. We compared children's life pattern before and after the introduction of the no nap interventions, and found that the children fell asleep at earlier time, show shorter sleep latency, and lighter morning moodiness. We entered children's supper time, bathing time, and mothers' bedtime into formula of multiple regression analysis as a independent variables for children's bedtime, and found that while children's supper time and bathing time showed high correlation, mothers' bedtime showed very low correlation with children's bedtime.
