Abstract：
To examine: 1) longitudinal adherence to the Canadian 24-Hour Movement Guidelines in a sample of infants and 2) associations between adherence to the guidelines over time and development.
Participants were 250 parent-infant dyads from the Early Movers project in Edmonton, Alberta. At 2, 4, and 6 months of age, physical activity, sedentary behaviour, sleep, and development were measured with a parental questionnaire that included items from the Ages & Stages Questionnaire (ASQ-3). Parents also reported the dates six major gross motor milestones were acquired during the first 18 months of life according to World Health Organization criteria. In a sub-sample (n = 93), movement behaviours were also measured with a time-use diary at 2, 4, and 6 months and gross motor development was measured by a physiotherapist using the Alberta Infant Motor Scale (AIMS) at 6 months. Guideline adherence was defined as: 1) ≥ 30 min/day of tummy time, 2) no screen time, some reading time, no restrained bouts > 1 h (time-use diary only), and 3) 14-17 h (2 months) or 12-16 h (4 and 6 months) of sleep per 24-h period. Generalized estimating equations were conducted as well as linear mixed models and linear regression models that adjusted for demographic characteristics.
Few infants met the guidelines at all time-points (questionnaire: 2%; time-use diary: 0%). Infants that met a recommendation at 2 months, compared to those that did not, were 1.8-8.2 times more likely to meet that recommendation at subsequent time-points. Meeting more recommendations across time-points, according to both measures, was associated with a higher mean ASQ-3 gross motor score. Each additional time-point of tummy time recommendation adherence (questionnaire-measured) was associated with a 5-11-day earlier acquisition of independent sitting, crawling, and independent standing milestones. In the sub-sample, each additional time-point of guideline adherence was associated with a 16% higher AIMS score at 6 months.
Guideline adherence was low across the first 6 months of infancy. Overall, meeting more recommendations over this period appeared important for gross motor development. Parents and caregivers should be targeted as early as possible with guideline dissemination and activation strategies to promote healthy infant development.

摘要：
背景：检查：1）在婴儿样本中纵向遵守加拿大24小时运动指南，以及2）随着时间的推移遵守指南与发育之间的关联。
方法：参与者是来自埃德蒙顿早期移动者项目的250个父母-婴儿二元组合，艾伯塔省.在2、4和6个月大的时候，身体活动,久坐的行为，睡眠,和发展是通过父母问卷测量的，其中包括来自年龄和阶段问卷（ASQ-3）的项目。父母还报告了根据世界卫生组织标准在生命的前18个月中获得六个主要的总运动里程碑的日期。在子样本(n=93)中，我们还在第2,4和6个月时使用日记测量了运动行为,理疗师在第6个月时使用艾伯塔省婴儿运动量表(AIMS)测量了粗大运动发育.指南依从性定义为：1）≥30分钟/天的腹部时间，2）没有屏幕时间，一些阅读时间，没有限制的回合>1小时(仅限使用时间日记)，和3）每24小时睡眠14-17小时（2个月）或12-16小时（4和6个月）。进行了广义估计方程以及针对人口统计学特征进行调整的线性混合模型和线性回归模型。
结果：几乎没有婴儿在所有时间点都符合指南（问卷：2％；使用时间日记：0％）。在2个月时符合建议的婴儿，与那些没有的相比，在随后的时间点满足该建议的可能性增加1.8-8.2倍。跨时间点满足更多建议，根据这两项措施，与较高的平均ASQ-3粗大运动评分相关。腹部时间建议依从性的每个额外时间点（问卷调查）与5-11天之前的独立坐姿相关，爬行,和独立的里程碑。在子样本中，指南依从性的每个额外时间点与6个月时AIMS评分提高16%相关.
结论：在婴儿期的前6个月中，指南依从性较低。总的来说,在此期间，满足更多建议对于大型汽车发展似乎很重要。父母和照顾者应尽早有针对性地传播指南和激活策略，以促进婴儿健康发育。
