Children can spend substantial amounts of leisure time in sedentary activities, dominated by TV/screen time. However, objective real-time measurement of activities after school among young school children is seldom described.
School children (n = 246, 5-7 years old, mean 6.0) and their parents were recruited by random selection from 14 schools across Sydney, Australia. Parents used a real-time objective measure (Experience Sampling Method, ESM) to record children's activities and whether they were indoors or outdoors at 3 random times each day after school. Data were collected across 4 weekdays in 1 week and then, 13 weeks later, another 4 weekdays in 1 week.
Results were based on 2940 responses from 214 child-parent dyads showed that 25% of behavior involved physical activity, 51% was spent in sedentary activities, and 22% was TV/screen time. Most instances (81%) occurred indoors.
Despite a high proportion of TV/screen time, children were also engaged in a range of other sedentary and physically active pursuits after school. Hence TV/screen time is not a suitable proxy for all sedentary behavior, and it is important to gather information on other non-screen-based sedentary and physically active behaviors. Future research is warranted to further investigate after-school activities in young primary school children.
儿童在久坐活动中会花费大量休闲时间,其中以看电视/屏幕时间为主。然而,很少有研究描述对低龄学童放学后活动的客观实时测量。
从澳大利亚悉尼的14所学校中随机选取学童(n = 246,5 - 7岁,平均6.0岁)及其家长。家长使用一种客观实时测量方法(经验取样法,ESM),在每天放学后的3个随机时间记录孩子的活动以及他们是在室内还是室外。数据在1周内的4个工作日收集,然后在13周后,再在1周内的4个工作日收集。
来自214对儿童 - 家长二元组的2940份回复显示,25%的行为涉及体育活动,51%用于久坐活动,22%是看电视/屏幕时间。大多数情况(81%)发生在室内。
尽管看电视/屏幕时间占比很高,但儿童放学后也参与了一系列其他久坐和体育活动。因此,看电视/屏幕时间并非所有久坐行为的合适替代指标,收集其他非屏幕类久坐和体育活动的信息很重要。未来有必要开展研究进一步调查小学低年级儿童的课外活动。
