目的了解北京城区小学生体力活动水平状况,为制定干预措施提供科学依据。方法随机抽取海淀区城区2所小学,在其中一所小学中随机选取40名4-6年级学生(男生22名,女生18名)携带加速度计型计步器(Lifecorder,Kenz Co.日本),记录7d的体力活动水平。同时于两所学校4-6年级各随机抽取1个班,抽到的238名同学(男生125名,女生113名)为调查对象,采用自填式问卷调查学生本学期的体力活动及静态生活方式的状况。结果计步器记录的总步数为8491步(天,中高强度体力活动时间为41.2±10.9min(d。被调查者95.4%住楼房,50.4%采用低能量消耗的交通方式。91.8%每周参加1-6个非体育类的课外补习班,34.7%没有参加课外体育训练班.每天不做家务,长时间看电视及玩电子游戏(≥2h(d)的比例分别为24.8%,15.1%及6.8%。结论中国城市小学生体力活动水平低于欧美发达国家的儿童体力活动水平及国际组织的推荐值。学业压力可能是影响体力活动的突出危险因素。应加强以提高体力活动水平为目的的健康促进活动。
Objective To understand the physical activity level of pupils in Beijing urban area and provide a scientific basis for making intervention measures. Methods Two elementary schools in Haidian District were randomly selected. 40 grade 4-6 students (22 boys and 18 girls) were randomly selected from one primary school to carry accelerometer pedometer (Lifecorder, Kenz Co. Japan) Record 7d physical activity level. In the meantime, 238 students (125 boys and 113 girls) were randomly selected from two grades 4-6 in each school. The questionnaires were used to investigate students’ physical activity and static life in this semester Mode of situation. Results The total number of steps recorded by the pedometer was 8491 steps (day, medium and high intensity physical activity time was 41.2 ± 10.9min (d. 95.4% of respondents lived in buildings and 50.4% used low energy consumption modes of transport .91.8% Participating in 1-6 non-sports extra-curricular classes, 34.7% did not participate in extra-curricular sports training classes. Daily domestic work, long time watching television and playing video games (≥ 2h (d) were 24.8%, 15.1% And 6.8% respectively.Conclusion The level of physical activity of urban primary school children in China is lower than that of children in developed countries in Europe and the United States and the recommendation of international organizations.Study stress may be the prominent risk factor of physical activity.It should be strengthened to improve the level of physical activity Health promotion activities.
