A questionnaire survey on physical activity, health-related QOL and depression during the junior high school years

Abstract

A questionnaire survey was conducted to assess the physical activity, health-related QOL and depression of junior high school students. The subjects were 1,332 students from 5 public junior high schools in a certain city；valid responses were obtained from 1,289 students. The International Physical Activity Questionnaire（IPAQ）was used for assessing physical activity, the Pediatric Quality of Life Inventory （PedsQL TM ）for health-related quality of life（QOL), and the Depression Self-Rating Scale for Children （DSRS-C）for depression tendency.With regard to physical activity between males and females and among different grades, there was a significant difference in the amount of vigorous-intensity activity（in terms of days, hours, and total activity time of 1 week). However, no significant difference was observed in walking. In the different age groups, the difference was observed in moderate-intensity activity（time, total activity time of 1 week）and energy expenditure. No significant difference was observed between males and females in holiday time is sitting activity was not observed in the grades. With regard to health-related QOL, a significant difference was observed between male and female students in the emotional function. The percentage calculated for each grade revealed that the female students showed higher depression tendency than the male students and that the number of students exceeding the cut-off score, which was determined to indicate depression tendency, increased as they advanced to the next grade. While the score maintained around 30％ from the 1st year to 3rd year in the female students, it showed about 30％ only in the 3rd year in the male students. Furthermore, one in three male and female 3rd year junior high school students was determined to have depression tendency. Therefore, it is necessary to reconsider the current cut-off score when using it to assess junior high school students.Key words：Junior high school students, physical activity, health-related QOL, depression, questionnaire 中学生，身体活動量，健康関連 QOL，抑うつ，アンケート

Association between physical activity duration and depressive symptoms in adolescents: A longitudinal study in a rural city in Japan

“…The percentage of participants with depressive tendencies at 14 y was 8.9%, which was significantly lower than the 23.3% reported by Denda et al [2] and 25.1% reported by Kawakatsu et al [32]. Although not shown in the results of this study, the depressive tendencies of the overall number of participants, before excluding participants with depressive tendencies at 11 y, was 11.7% (n = 1540), which is lower than that of a previous study on the same age group in…”

“…Moreover, regarding the changes in DSRS-C scores by age, a study conducted in Sweden in 1997 focusing on adolescents aged 13-18 years found no significant age-related differences in scores [38]. However, the potential for agerelated changes to function as confounding factors cannot be entirely dismissed [32]. In the current study, data indicating depressive tendencies at 11 y were excluded; hence, the impact of this variable has not been examined.…”

Effectiveness of school-based brief cognitive behavioral therapy with mindfulness in improving the mental health of adolescents in a Japanese school setting: A preliminary study

“…Studies on depression and anxiety among Japanese adolescents have reported that female adolescents exhibit higher scores for both depression ( Kawakatsu et al, 2014 ) and anxiety ( Ishikawa et al, 2009 ), compared with male adolescents. This could have been associated with girls showing greater interest in mindfulness and different rates of homework completion.…”

“…Cammin-Nowak et al (2013) reported two findings on homework assignments in CBT; first, therapies that incorporate homework assignments are associated with better outcomes, compared with therapies without homework; second, patients who complete homework show greater improvement, compared with those who do not (Kazantzis et al, 2000(Kazantzis et al, , 2010Mausbach et al, 2010;Klingbeil et al, 2017). Studies on depression and anxiety among Japanese adolescents have reported that female adolescents exhibit higher scores for both depression (Kawakatsu et al, 2014) and anxiety (Ishikawa et al, 2009), compared with male adolescents. This could have been associated with girls showing greater interest in mindfulness and different rates of homework completion.…”

“…Japanese adolescents are displaying increased mental health problems. In Japan, 25.9% of junior high school students exhibit high depressive tendencies ( Kawakatsu et al, 2014 ). Using semi-structured interviews, Sato et al (2008) found that the prevalence of depression in Japanese junior high school students was 4.9% (boys: 2.2%; girls: 8.0%); the reported lifetime prevalence rate was 8.8% (boys: 6.2%; girls: 12.0%).…”
