身体活动和久坐行为习惯在幼儿期就已形成，但直到最近才有5岁及以下儿童的客观测量数据。这项研究提供了加拿大3-5岁儿童的体育活动和久坐行为的数据。数据是作为2009年至2011年加拿大健康措施调查的一部分收集的。一个具有全国代表性的样本（n = 459）的3-5岁的儿童在他们的清醒时间连续7天佩戴Actical加速度计。在60秒的时间段内收集数据，保留≥4个有效日的受访者进行分析。父母在一份问卷中报告了他们孩子的体育活动和屏幕时间习惯。84%的3-4岁儿童达到了每天总身体活动180分钟的身体活动指南，而18%的儿童达到了每天<1小时的屏幕时间目标。14%的5岁儿童达到了每天60分钟中度至剧烈体力活动（MVPA）的身体活动指南，而81%的儿童达到了每天<2小时的屏幕时间目标。3-4岁儿童平均累积总体力活动352 min/d，MVPA 66 min，5岁儿童平均累积总体力活动342 min/d，MVPA 68 min。孩子们大约有一半的清醒时间是久坐不动的，平均每天花2个小时在屏幕前。只有15%的3-4岁奥尔兹和5%的5岁奥尔兹同时符合体育活动和久坐行为指南。在减少久坐行为的同时促进身体活动在生命的各个阶段都很重要。本研究的结果表明，这些行为在加拿大幼儿中仍有很大的改善空间。
Physical activity and sedentary behavior habits are established during early childhood, yet only recently has objectively measured data been available on children aged 5 years and younger. This study presents data on the physical activity and sedentary behaviors of Canadian children aged 3–5 years. Data were collected as part of the Canadian Health Measures Survey between 2009 and 2011. A nationally-representative sample (n = 459) of children aged 3–5 years wore Actical accelerometers during their waking hours for 7 consecutive days. Data were collected in 60-sec epochs and respondents with ≥4 valid days were retained for analysis. Parents reported their child’s physical activity and screen time habits in a questionnaire. Eighty-four percent of 3–4 year old children met the physical activity guideline of 180 minutes of total physical activity every day while 18% met the screen time target of <1 hour per day. Fourteen percent of 5 year old children met the physical activity guideline of 60 minutes of daily moderate-to-vigorous physical activity (MVPA) while 81% met the screen time target of <2 hours per day. Children aged 3–4 years accumulated an average of 352 min/d of total physical activity and 66 minutes of MVPA while 5 year old children accumulated an average of 342 min/d of total physical activity and 68 minutes of MVPA. Children were sedentary for approximately half of their waking hours and spent an average of 2 hours per day in front of screens. Only 15% of 3–4 year olds and 5% of 5 year olds are meeting both the physical activity and sedentary behavior guidelines. Promoting physical activity while reducing sedentary behavior is important at all stages of life. The findings of the present study indicate that there remains significant room for improvement in these behaviors among young Canadian children.
