The purpose of this study was to examine the cycle structure about life habits in junior high school students. The participants were 9,167 children from 1st to 3rd grader in Setagaya city. Survey items included life habits (breakfast intake habit, sleeping habit, exercise habit, electronic media usage habit, and so on) and subjective symptoms of fatigue. We analyzed validities of “life before start of class” “subjective symptoms at school” and “life after school”. After that the cycle structure about those was analyzed by using structural equation modeling, using multiple group structural equation modeling to consider about sex difference. The main results in this study were as follows. It was confirmed that one day living have Cycle structure and not sex difference. Additionally, it was also confirmed that path coefficient from “life after school” to “life before start of class” was highest in cyclic structure about life habits in junior high school. All models exhibited good conformity modeling and confirmed validities of three latent variable and cycle structure about life habits in junior high school students.
These finding indicated that improvement of “life after school” is the most influential for good lifestyle habit. Although it has less impact than “life after school” improvement of “life before start of class” and “subjective symptoms at school” also have significance.
