项目摘要

[Introduction] In this study, the states of obesity, physical activities, and diet of 4th-6th graders were examined in an agricultural area of the Tohoku district, where most pupils were driven to and from school. The physique (height, weight, BMI), physical activity level (pedometer with an acceleration sensor ; Kenz), and nutritional intake (calculated with Wellness21, Top-Business) were investigated in 226 elementary school pupils during a 7-day period including 2 or 3 holydays in fall.[Results] The percentage of obese children was higher than the national average. After school, the pupils spent the longest time in watching TV, followed by playing outside. Most of them were driven to school and back home, and the mean time of walking to and back from school was 4 minutes. The mean number of steps of daily walking was 13,075 in the males and 10,235 in the females, but it decreased on holidays to about 60% of the numbers on weekdays. A significant correlation was observed between the … More activity index and the number of steps of walking, and the numbers of steps that correspond to a relatively low activity level (AI 1.5) and an appropriate activity level (AI 1.7) were estimated to be 13,665 and 22,438, respectively. Their diet was characterized by marked deficiency of iron and calcium, high intakes of meat and sweets, and low intakes of vegetables and fruits. A smaller percent of overweight children practiced sports than normal weight children.[Conclusions] The following characteristics were observed in the subjects of this study : 1) a high percentage of obese children, 2) inadequacy of the number of walking steps, and 3) a lower percentage of obese children participating in sports activities than non-obese children. Therefore, an increase in the physical activity level is considered to be necessary for the prevention of obesity. For this purpose, in addition to administrative measures to increase exercise opportunities in the community such as the establishment of a general sports club, actions such as encouraging pupils to walk to school are considered to be effective.

[简介] 这项研究在东北地区的一个农业区（大多数学生上下学都由汽车接送）对 4 至 6 年级学生的肥胖、体力活动和饮食状况进行了调查。对226名小学生的体质（身高、体重、BMI）、体力活动水平（带有加速度传感器的计步器；Kenz）和营养摄入量（用Wellness21、Top-Business计算）进行了为期7天的调查，其中包括秋季的2或3个节日。 [结果] 肥胖儿童的比例高于全国平均水平。放学后，学生们看电视的时间最长，其次是在外面玩耍。他们中的大多数人开车上下学，步行上下学的平均时间为 4 分钟。男性每日平均步行步数为 13,075 步，女性为 10,235 步，但节假日期间步行步数下降至工作日的 60% 左右。活动指数与步行步数之间存在显着相关性，相对较低活动水平（AI 1.5）和适当活动水平（AI 1.7）对应的步数估计分别为 13,665 和 22,438。他们的饮食特点是铁和钙明显缺乏，肉类和甜食摄入量较高，蔬菜和水果摄入量较低。超重儿童参加体育活动的比例低于正常体重儿童。[结论]本研究对象存在以下特点：1）肥胖儿童比例较高；2）步行步数不足；3）肥胖儿童参加体育活动的比例低于非肥胖儿童。因此，增加体力活动水平被认为对于预防肥胖是必要的。为此，除了建立综合体育俱乐部等增加社区锻炼机会的行政措施外，鼓励学生步行上学等行动也被认为是有效的。较少的
