Background: In Japan, the sales of energy drinks (ED) are growing rapidly. This has led to concerns that consumption of ED could have a negative health impact for individuals, including children.Objective: The purpose of this study was to confirm the intake of ED, the characteristics of consumers' physical symptoms/behaviors, and the perception of ED based on the results of a questionnaire survey for school children.Methods: The subjects were 5,984 children from 5th grade of elementary schools to 3rd grade of high school in 16 schools (5 elementary schools, 6 junior high schools, 5 high schools) at 6 rural and metropolitan Japanese prefectures. All investigations were conducted from May 2018 to March 2019. The questionnaire used in this study gathered information regarding ED intake, physical symptoms/behaviors, and the perception of ED.Results: The main results in this study were as follows. 1) Older students were more consume ED than younger students, and boys were more than girls to consume ED (elementary school: 45.5% boys, 27.9% girls, junior high school: 58.0% boys, 32.8% girls, and high school: 67.6% boys, 45.4% girls). 2) The analysis of the relationship between the ED intake frequency and physical symptoms indicated that the complaints of physical symptoms such as ‘headache (OR=1.573, 95% CI=1.281-1.931),' ‘stomachache (OR=1.545, 95% CI=1.224-1.949),' ‘appetite loss (OR=1.629, 95% CI=1.293-2.053),' ‘nausea (OR=1.667, 95% CI=1.251-2.222),' ‘tiredness (OR=1.285, 95% CI=1.023-1.614),' ‘lethargy (OR=1.382, 95% CI=1.120-1.706),' ‘dizziness (OR=1.369, 95% CI=1.108-1.692),' ‘fogginess (OR=1.621, 95% CI=1.231-2.134),' ‘cardiac pain (OR=1.537, 95% CI=1.168-2.021)' and ‘malaise (OR=1.557, 95% CI=1.267-1.915)' were higher in the group who consumed ED habitually (more than once a week). Similarly, in the analysis of the relation between the ED intake frequency and behaviors, ‘late bedtime (OR=1.338, 95% CI=1.092-1.640),' ‘bad sleep onset (OR=1.649, 95% CI=1.311-2.074),' ‘wake after sleep onset (OR=2.056, 95% CI=1.528-2.766)' and ‘lack of breakfast (OR=3.453, 95% CI=2.546-4.684)' were also higher in the habitual ED intake group. 3) The four factors, ‘vitality', ‘vogue,' ‘ineptness' and ‘distrust' were extracted regarding students' perception of ED held by children. Additionally, it was confirmed that the habitual ED intake group had higher factor scores of ‘vitality' and ‘vogue,' while their factor scores of ‘ineptness' and ‘distrust' were also significantly lower.Conclusion: In this study, we were able to show the real state of ED intake, the characteristics of consumers' physical symptoms/behaviors, and the perception of ED. Therefore, social countermeasures were considered necessary.

<p>Background:In recent Japan, the sleep situations of children are worried about. As one background of such a problem, the screen thyme of children increase is regarded as uneasiness. Therefore, the practices of "no media" which limits screen time are spreading all over the country.</p><p>Objective:The purpose of this study was to inspect the effects of the "no-media" practice in junior high school.</p><p>Methods:Subjects were 672 children at a public junior high school in Shizuoka. All investigations were carried out on control day and practice period in October 2014. The sleep situation and subjective symptoms of fatigue were measured in this survey.</p><p>Results:Subjects were early to bed and early to rise. There were also few shortage and issues of sleep. Additionally, they had few subjective symptoms of fatigue and Internet addiction tendency. Furthermore, as a result of having inspected the "no media" practice, the bed duration was significantly earlier and sleep time was also significantly longer in practice period. The subjective symptoms of fatigue in practice period were decreased. In this study, the sleep situations and subjective symptoms of fatigue by the difference of the challenge item in this practice were also analyzed. As a result, in the group which challenged the practice of "no media", it was shown that the sleep situation was improved and tiredness was decreased.</p><p>Conclusion:From the above facts, we reached the conclusion that the "no media" practice analyzed in this study is effective in children's health.</p>

This study aims to clarify the relationship the amount of physical activity between children’s exercise play in the morning and the achievement rate of daily recommended physical activity. We found that the amount of physical activity during morning exercise with the intensity LC3-9 was 9-13 minutes; LC4-9, was 7-10 minutes; LC7-9, 2-4 minutes; and the number of steps were 1,600-2,200 . The target number of steps to achieve the recommended physical activity time of 60 minutes was 12,300 steps in LC3-9, including daily activities, and the achievement rate depended on the frequency of morning exercise (High frequency group (a) > Medium frequency group (b) > Low frequency group (c), p<.001). The target number of steps with medium intensity or higher was 15,300 steps in 60 minutes, the target steps with high intensity was 15,700 steps in 25 minutes. The achievement rate was varid with the frequency of exercise.

The purpose of this study was to make clear the relationship between sleeping habits and sleeping problems and/or physical discomforts among junior high school students. The subjects were comprised of 146 boys and 170 girls in three public junior high schools. The investigation was carried out by a questionnaire in September 2003. The questionnaire contained questions about the time subjects go to bed, time subjects wake up, sleeping problems and physical discomfort. The main findings were as follows: 1) The time subjects go to bed becomes later with increasing age among both boys and girls (p<0.05). Meanwhile, the fluctuations in time to bed showed no significant differences according to sex or grade. 2) The group who went to bed late had significantly higher values for sleeping problem scores and physical discomfort scores (p<0.05). 3) The sleeping problem scores according to fluctuations in time to bed were: for the low fluctuations group, 12.5±13.7 points, 18.7±17.2 points for the middle fluctuations group, and 24.3±20.5 points for the high fluctuations group. The sleeping problem scores for the high fluctuations group were significantly higher than it was for the low fluctuations group (p<0.05). 4) The physical discomfort scores were 20.1±29.8 points for the low fluctuations group, 29.5±30.3 points for the middle fluctuations group and 41.3±30.2 points for the high fluctuations group. The physical discomfort scores for the high fluctuations group were significantly higher than those for the low and middle groups (p<0.05).<br>From the above, it was shown that there is a need for the regulation of time to bed to be added to traditional health education.

自然環境に恵まれた都心部で1776組の親子を対象にした質問紙調査を行なった。子どもたちが放課後を過ごす場は低学年では学校や公園で、高学年は塾や習い事の頻度が高く、外遊びが少ない実態が明らかになった。体を動かして遊ぶ、自然環境で遊ぶ、水辺で遊ぶ時間が多いほどSDQの情緒、仲間関係、向社会性は良好だった。ゲーム時間は多動に関連していた。DSM-5/ADHDでは、からだを動かして遊ぶ時間が30分以上であると不注意傾向が少なくなることが示された。まち探検&遊び活動のアクション・リサーチでは活動量の個人間のばらつきが大きく、最後の30分間に活発に活動している群は不活発群より有意に覚醒度が上昇した。

The purpose of this study was to make clear the relationship between body temperature and lifestyle in elementary school children. The subjects were comprised of 79 boys and 102 girls in children from third to fifth grader. The investigation was carried out by the measurement of body temperature and questionnaire of lifestyle from November to December 2008 and the same period 2009. The body temperature was measured in an axilla for 10 minutes. The questionnaire was composed the sleep onset time, the getting up time, the TV hour, the game hour, the internet/mobile telephone hour, the exercise hour, the learning hour, the evacuation situation and the breakfast intake situation. The main findings were as follows : 1) The issue of low body temperature tendency worried about since 1980s was not still solved. However, about 20% of all measured values was more than 37.0°C. 2) The group of low body temperature which was less than 36.0°C at the time of getting up showed a low temperature level through day. 3) The group of high body temperature which was more than 37.0°C at the time of getting up showed a flat temperature change through day. 4) The relationship between temperature and lifestyle in girls was not clarified. On the other hand, it was shown that the internet/mobile telephone hour was long, the sleep onset time was late and the sleep hour was short in low body temperature group of boys.

The purpose of this study was to examine the bone stiffness of healthy girls during their growth period and factors affecting on such stiffness. The subjects were 302 secondary school girls in Tokyo. Parameters examined included the body characteristics (standing height, body weight, bone stiffness measured by ultrasound, muscle thickness measured with the ultrasound B-mode system), extension power of the lower limb (containing the knee and hip joints), and a questionnaire about the daily intake of milk, kinds of meals and number of years from menophania. These examinations were carried out in June 1997.Results were summarized as follows : 1) From the observation of bone stiffness in secondary school girls, it appears that bone stiffness increases during the junior high school period. In other words, the bone stiffness of the subjects had almost reached on adult level by high school. 2) A significant positive correlation was recognized between chronological age and bone stiffness (r=0.365, p<0.05) . A positive correlation also existed between the years from menophania and bone stiffness (r=0.477, p<0.05) . These coefficients showed that the years from menophania correlate with bone stiffness more closely in comparison with chronological age. 3) In the period when short comparatively years from menophania, body characteristics, which were the index of maturity, correlated to bone stiffness. However, muscle thickness/power, which was related to exercise habit, became the major parameter correlating with bone stiffness. These results suggest that factors affecting bone stiffness should differ according to the growth period. 4) Comparison of different athletic clubs showed that the bone stiffness of volleyball players was higher than that of control. These data suggest that physical education class, which was given 3 times a week, is not enough for total body development in both quality and quantity. In other words, physical education should be better matched with total physical development, including the growth of healthy bones.
