[Effects on health status in students from attending a "juku"].

Between November and December 1993 a questionnaire survey concerning the lifestyle and health status was performed on 1.314 elementary school children living in Tokyo and its suburbs. In this study the following items were included: 1) sleeping habits, 2) physical activity, 3) playing habits, 4) eating habits, 5) attending a "juku", private cram school to prepare children for entrance examinations, 6) commuting hours, 7) 20 subjective symptoms regarding health, and so on. The results were as follows: 1. 61.9% of students were attending a "juku". 2. The number of hours of sleep, playing after school and watching TV decreased with the frequency of attending a "juku". The students who were attending "juku" more than 3 times a week had the shortest number of those hours, and the students who did not attend any "juku" had the longest of those hours. 3. To determine health status, 20 subjective symptoms were scored. The average number of subjective symptoms was 5.0. That of the students who were attending "juku" more than 3 times a week was 5.5. 4. Of the 20 subjective symptoms, 7 items were correlated to the frequency of attending "juku". To remove the effect of other factors, multiple logistic regression analysis was applied to determine correlation of 7 subjective items and other factors including attending "juku". As a result attending "juku" more than three times a week were associated with the two symptoms of "sleepy" and "eye fatigue".
