我国儿童青少年久坐现状调查研究

Investigation and Research on the Current Situation of Chinese Children and Adolescents'Sedentariness

久坐对我国儿童青少年健康的危害不容忽视,但是目前我国对该领域的认识仍旧不够。本文旨在呈现当前我国儿童青少年的久坐现状。调查发现,我国儿童青少年久坐现状严峻,具体表现为总的久坐频率高、时间长;教育相关久坐是儿童青少年久坐的主要类型;不论是上学日还是寒暑假期间,学习、读书看报和写作业都为久坐的积累贡献了巨大的比例;绝大多数儿童青少年每次花在看电视、使用电子设备进行娱乐的时长都能控制在半小时之内,但在寒暑假期间该类行为的频率和总时长明显超过上学日期间;花在静态交通上的久坐行为在上学日期间的频率相较于寒暑假期间更高,而用于其他闲暇活动的久坐行为的频率和时长在寒暑假期间普遍更高;除此之外,在农村就学和在城市就学的儿童青少年各种类型的久坐行为分布并无显著差异。

Sedentariness is harmful to the health of children and adolescents in China.Though it is a phenomenon that cannot be ignored,insufficient attention has been paid to it.The article aims to present the current situation of children and adolescent's sedentary behaviors,which seem to be severer.For example,children and adolescents are usually discovered to be sedentary over a long period of time,and mostly during educational activities.Whether it is school days or during winter and summer vacations,stting there to study,read newspapers or do homework all take a large amount of time.The vast majority of children and adolescents can spend less than half an hour each time they spend watching TV and using electronic devices for entertainment.However,the frequency and total duration of similar behaviors are significantly greater than that during school days;the frequency of sedentary behaviors spent on static traffic during school days is higher than that during winter and summer vacations,while the frequency and total duration of sedentary behaviors used for other leisure activities is generally higher during winter and summer vacations.No significant differences have been found in the distribution of various types of sedentary behaviors between children and adolescents who study in rural areas and those who study in cities.
