目的许多肥胖相关的慢性疾病都源于儿童时期的不良习惯。本研究的目的是描述9个月大婴儿的身体活动水平和模式，并检查相关性。了解这些因素对于提高婴儿身体活动干预计划的有效性是必要的。方法选取来自中国澳门澳门的143对新生儿-母亲配对。使用Actigraph GT 3X+加速度计评估身体活动（PA），并通过问卷调查收集人口统计学变量。结果最重要的发现是：（1）婴儿在工作日有更多的屏幕时间（p = 0.044）;（2）婴儿和母亲在上午8点最不活跃。(both工作日和周末）在早上和最活跃的在晚上7点。（平日）和晚上8时（周末）晚上;（3）婴儿的PA水平与母亲周末的PA强度显著相关（r = .192，p = .036），尤其是母亲在早晨和晚上的较低强度：（4）母亲BMI预测9个月大婴儿的PA水平（R2 = .06，β = 29.188，p = .009）。结论：从婴儿早期开始，婴儿的身体活动促进计划应该是有时间特异性的。这项研究是第一个检查9个月大婴儿PA水平，模式和相关性的研究之一。本研究结果可作为改善澳门及区内婴幼儿健康生活方式干预效果的参考。
Objectives Many obesity-related chronic diseases originate from unhealthy childhood habits. The aim of this study was to describe 9-month-old infants’ physical activity levels and patterns and to examine the correlates. Understanding these factors is necessary for improving the effectiveness of physical activity intervention programs for infants. Methods In total, 143 infant–mother dyads from Macau, SAR China, participated in this study. Physical activity (PA) was assessed by using the Actigraph GT3X+ accelerometer and the demographic variables were collected by questionnaires. Results The most important findings were that: (1) infants had more screen time during weekdays (p = .044); (2) infants and mothers were least active at 8 a.m. (both weekdays and weekends) in the morning and most active at 7 p.m. (weekdays) and 8 p.m. (weekends) in the evening; (3) infants’ PA levels significantly correlated with their mothers’ PA intensities during the weekends (r = .192, p = .036), especially the mothers’ lower intensities in the mornings and evenings; (4) maternal BMI predicted the PA levels of the 9-month-old infants’ (R2 = .06, β = 29.188, p = .009). Conclusions for Practice Physical activity promotion programs for infants should be time-specific starting from early infancy. This study was one of the first to examine 9-month-old infants’ PA levels, patterns and correlates. The results may be helpful in improving the effectiveness of future healthy lifestyle intervention programs for infants in Macau and in the region in general.
