高校生の疲労自覚症状について

高校生の生体負担度の研究 第二報

抄録

A survey was conducted on subjective symptoms of fatigue in senior high school students (including first grade of post-graduate course) before going to bed one day before, before lectures, after lectures and going to bed, on the classification by sex, grade and term, and in relation to four factors of life time which are club activity, attending to school, study at home and sleep.
The following results were obtained.
1) “Give a yamn” and “Become drowsy” showed higher frequency of complains before lectures, after lectures and before going to bed among 30 items of subjective symptoms of fatigue.
2) The frequency of complains in boys was higher than that in girls, where there were 31 cases in 33 cases of showing the significant difference between boys and girls among surveyed 99 cases on the classification by grade, time of survey and common component of symptoms.
3) The frequency of complains of the third grade-boy students was higher than those of other grade-boy students, where there were 7 cases in 8 cases of the significant difference among surveyed 72 cases on the classification by grade, time of survey and common component of symptoms.
But, the frequency of complains of the third grade-girl students showed only a few cases of the significant difference in comparison with other grade-girl students.
4) Both of the frequency of complains belonging to symptoms of drowsiness and dullness of the second and third grade-girl students and that of difficulty in concentration of all grade-girl students were higher than that of the first grade-girl students of post-graduate course after lectures and before going to bed, where there were 10 cases of the significant difference among surveyed 24 cases in the former and 15 cases of the significant difference among surveyed 24 cases in the latter on the classification by grade, term, time of survey and common component of fatigue.
5) The coefficient of correlation between frequency of complains and four factors of life time were 0.45 at most, where club activity time showed 6 cases, sleeping time showed 7 cases and studying time showed 13 cases in 29 cases of showing ρ=0 (ρ: coefficient of correlation of population) under 0.05 of risk rate among surveyed 726 cases on the classification by sex, grade, term, time of survey and common component of symptoms.
6) The multiple coefficient of correlation between four factors of life time and frequency of complains used by the multiple regression equation were tend to be higher than the each coefficient of correlation between them.
