这项研究旨在解决早期为国家和国际运动行为指南提供信息的证据的方法学局限性。具体来说,主要目标是检查婴儿身体活动的纵向关联(即,肚子时间)和久坐行为(即,回到时间,屏幕时间,阅读时间,限制时间)与总电机发展。二级和三级目标是检查以下各项的纵向关联:(1)婴儿身体活动和久坐行为与沟通,精细电机,个人社会,解决问题的发展,和(2)睡眠时间与主要和次要结果。
参与者是来自埃德蒙顿早期移动项目的411名父母和他们的婴儿,加拿大。身体活动,久坐的行为,在第2、4和6个月时使用父母问卷和年龄和阶段问卷(ASQ-3)发育筛查工具测量睡眠。家长报告了六个主要的总运动里程碑的日期(即,独立坐姿,爬行,辅助站立,辅助行走,独立站立,独立行走)是根据世界卫生组织的标准在生命的前18个月获得的。在子样本(n=125)中,在6个月时使用艾伯塔省婴儿运动量表(AIMS)评估总运动发育.
随着时间的推移,更高的腹部时间与更高的ASQ-3粗大运动和个人社会发展得分显着相关。6个月时AIMS总分更高,并提前获得所有总电机里程碑。跨时间点的较高阅读时间与较高的ASQ-3精细运动显着相关,毛马达,个人社会,以及随着时间的推移的总发展分数。相比之下,较高的时间点的回复时间与6个月时较低的AIMS总分和较晚的辅助站立获得显着相关,辅助行走,独立行走。同样,跨时间点的较高限制时间与后期获得支持步行显着相关。
腹部时间始终与更高级的粗大运动发育和阅读与更高级的总体发育相关。然而,观察到背部和限制时间的一些有害关联。研究结果支持促进腹部时间和某些久坐行为(即,阅读)在幼儿中促进全面发育。
This study aimed to address methodological limitations of the evidence that informed national and international movement behaviour guidelines for the early years. Specifically, the primary objective was to examine the longitudinal associations of infant physical activity (i.e., tummy time) and sedentary behaviour (i.e., back time, screen time, reading time, restrained time) with gross motor development. Secondary and tertiary objectives were to examine longitudinal associations of: (1) infant physical activity and sedentary behaviour with communication, fine motor, personal-social, and problem solving development, and (2) sleep time with primary and secondary outcomes.
Participants were 411 parents and their infants from the Early Movers project in Edmonton, Canada. Physical activity, sedentary behaviour, and sleep were measured with a parental questionnaire and the Ages & Stages Questionnaire (ASQ-3) developmental screening tool was administered at 2, 4, and 6 months. Parents reported the dates six major gross motor milestones (i.e., independent sitting, crawling, assisted standing, assisted walking, independent standing, independent walking) were acquired in the first 18 months of life according to World Health Organization criteria. In a subsample (n = 125), gross motor development was assessed using the Alberta Infant Motor Scale (AIMS) at 6 months.
Higher tummy time across time points was significantly associated with higher ASQ-3 gross motor and personal-social development scores over time, higher total AIMS scores at 6 months, and earlier acquisition of all gross motor milestones. Higher reading time across time points was significantly associated with higher ASQ-3 fine motor, gross motor, personal-social, and total development scores over time. In contrast, higher back time across time points was significantly associated with lower total AIMS scores at 6 months and the later acquisition of assisted standing, assisted walking, and independent walking. Similarly, higher restrained time across time points was significantly associated with a later acquisition of supported walking.
Tummy time was consistently longitudinally associated with more advanced gross motor development and reading with more advanced total development. Whereas, some detrimental associations were observed for back and restrained time. Findings support the promotion of tummy time and certain sedentary behaviours (i.e., reading) in young infants to enhance overall development.
