Abstract

The present study collected data on 117 second-grade students and 106 sixth-grade students at S elementary school and N elementary school in Saitama Prefecture regarding bedtime and rising time to elucidate the effect of early bedtimes and rising times on their diets and daily schedules. The effects of the duration and contents of daily physical activities on the students’ physique type and diets were also investigated. The results were as follows.<BR>1. The rising time, breakfast starting time, and dinner starting time were earlier, and the time from the rising time to the breakfast starting time was longer in the “early-bedtime and early-rising time group” than in the “late-bedtime and late-rising time group.” The “early-bedtime and early-rising time group” also had longer sleeping hours.<BR>2. The outdoor activity hours of the subjects of present study tended to be long in both the “early-bedtime and early-rising time group” and the “late-bedtime and late-rising time group” of both grades.<BR>3. Most students ate breakfast ; however, many did not eat a balanced breakfast (consisting of staple food, main dish, and drink and/or miso soup).
