For effective public health and surveillance it is important to document the proportion of young children who meet the new Australian Integrated 24 h Movement Guidelines for the Early Years and how these associate with health outcomes. We aimed to (i) assess compliance with the new Integrated 24 h Movement Guidelines for the Early Years in a sample of Australian toddlers; and (ii) ascertain whether compliance with the guidelines associates with weight status.
The sample comprised 202 toddlers (104 girls) aged 19.74 ± 4.07 months from the GET UP!
Participants wore accelerometers (Actigraph GT3X+) for 24 h over 7 consecutive days to assess physical activity, sedentary time and sleep. Parents reported participants' screen time. Weight and height were measured and body mass index (BMI) z-scores by age and sex were calculated. Analysis of Covariance (ANCOVA) was performed to test differences in BMI z-scores between participants complying with (i) none or any individual guideline, (ii) any combination of meeting two guidelines, and (iii) those who met all three guidelines, adjusting for child age, gender and socioeconomic status.
Only 8.9% of the sample met the overall 24 h movement guidelines. Most of the sample met the physical activity (96.5%) and sleep (79.7%) guidelines but only 11.4% met the sedentary behavior guideline. Average BMI Z-scores did not significantly differ between children who complied with none or any individual guideline, any combination of meeting two guidelines, and those who met all three guidelines (p > 0.05). Although the lack of significant differences, participants who accomplished any combination of two guidelines or all three guidelines appear to have had a lower BMI Z-score than those complying with one of the guidelines or none.
Just under 9% of our sample met the overall Australian 24 h Movement Guidelines for the Early Years. BMI was not associated with the accomplishment of any of the 24-h Movement Guidelines. Strategies to promote adherence to the 24-h movement guidelines in toddlers, particularly for screen time, are necessary, as promoting health-related behaviors in early childhood has the potential to provide children a strong foundation for lifelong physical and mental health.
为了有效地开展公共卫生和监测工作，记录符合澳大利亚新的幼儿24小时综合运动指南的幼儿比例以及这些比例与健康结果之间的关联非常重要。我们旨在：（i）评估澳大利亚幼儿样本对新的幼儿24小时综合运动指南的遵守情况；（ii）确定遵守这些指南是否与体重状况相关。
样本包括来自“起床！”研究的202名19.74±4.07个月大的幼儿（104名女孩）。参与者连续7天佩戴加速度计（Actigraph GT3X+）24小时，以评估身体活动、久坐时间和睡眠情况。家长报告参与者的屏幕使用时间。测量体重和身高，并计算按年龄和性别划分的体重指数（BMI）z评分。进行协方差分析（ANCOVA），以检验在遵守（i）无或任何一项单独指南、（ii）满足两项指南的任何组合、（iii）满足所有三项指南的参与者之间，BMI z评分的差异，并对儿童年龄、性别和社会经济地位进行调整。
样本中只有8.9%的幼儿符合整体24小时运动指南。大多数样本符合身体活动（96.5%）和睡眠（79.7%）指南，但只有11.4%符合久坐行为指南。在未遵守或遵守任何一项单独指南、满足两项指南的任何组合以及满足所有三项指南的儿童之间，平均BMI Z评分没有显著差异（p>0.05）。尽管没有显著差异，但完成两项指南的任何组合或所有三项指南的参与者的BMI Z评分似乎低于遵守一项指南或未遵守任何指南的参与者。
我们样本中不到9%的幼儿符合澳大利亚整体的幼儿24小时运动指南。BMI与遵守任何一项24小时运动指南均无关联。有必要采取策略来促进幼儿遵守24小时运动指南，特别是减少屏幕使用时间，因为在幼儿期促进与健康相关的行为有可能为儿童的终身身心健康奠定坚实基础。
