Individuals with Down syndrome (DS) are at greater risk for obesity than their peers who are developing typically. One factor contributing to an early onset of obesity is low levels of physical activity (PA). However, there is little known regarding PA patterns during infancy.
The purpose of this study was to examine the daily PA patterns in 22 infants developing typically and 11 infants with Down syndrome (aged 1-12 months) using Actigraph GT3X+ (wrist and ankle).
No significant differences between groups were identified in PA counts at the ankle. Both groups produced significantly more PA at the wrist than at the ankle and PA counts increased across months in age.
This study represents an important first step in establishing baseline PA patterns during infancy.
唐氏综合征（DS）患者比发育正常的同龄人患肥胖症的风险更高。导致肥胖症早发的一个因素是身体活动（PA）水平较低。然而，关于婴儿期的身体活动模式却知之甚少。
本研究的目的是使用Actigraph GT3X+（手腕和脚踝佩戴）来检查22名发育正常的婴儿和11名唐氏综合征婴儿（1至12个月大）的每日身体活动模式。
两组在脚踝处的身体活动计数没有显著差异。两组在手腕处产生的身体活动明显多于脚踝处，并且身体活动计数随着年龄增长而增加。
本研究是建立婴儿期身体活动基线模式的重要第一步。
