Children with cerebral palsy (CP) have lower habitual physical activity (HPA) than their typically developing peers. There are limited studies of HPA in young children with CP under the age of 5 years.
To investigate the relationships between HPA, sedentary time, motor capacity and capability in children with CP aged 4-5 years.
Sixty-seven participants were classified using Gross Motor Function Classification System (GMFCS), assessed for motor capacity using Gross Motor Function Measure (GMFM) and wore accelerometers for three days to measure HPA and sedentary time. Motor capability was assessed using parent-reported Pediatric Evaluation of Disability Inventory (PEDI) functional skills of mobility domain. Mixed-effects regression models were used for analyses.
GMFM was positively associated with HPA (mean difference (MD) = 19.6 counts/min; 95%CI = 16.6 to 22.7, p < 0.001) and negatively associated with sedentary time (MD = -0.6%; 95%CI = -0.7 to -0.5, p < 0.001). The PEDI was also positively associated with HPA (MD = 16.0 counts/min; 95%CI = 13.1 to 18.8, p < 0.001) and negatively associated with sedentary time (MD = -0.5%; 95%CI = -0.6 to -0.4, p < 0.001). After stratification for ambulatory status, GMFM and PEDI were associated with HPA and sedentary time in ambulant participants but not in non-ambulant participants.
Gross motor capacity and motor capability are related to HPA and sedentary time in ambulant children with CP aged 4-5 years.
脑瘫儿童（CP）的习惯性体力活动（HPA）低于其正常发育的同龄人。在 5 岁以下的 CP 幼儿中，HPA 的研究有限。
研究 4-5 岁 CP 儿童的 HPA、久坐时间、运动能力和运动能力之间的关系。
67 名参与者根据粗大运动功能分类系统（GMFCS）进行分类，使用粗大运动功能测量（GMFM）评估运动能力，并佩戴加速度计三天以测量 HPA 和久坐时间。使用家长报告的残疾儿童评估量表（PEDI）的移动领域的功能技能来评估运动能力。采用混合效应回归模型进行分析。
GMFM 与 HPA 呈正相关（平均差异（MD）=19.6 计数/分钟；95%CI=16.6 至 22.7，p<0.001），与久坐时间呈负相关（MD=-0.6%；95%CI=-0.7 至-0.5，p<0.001）。PEDI 也与 HPA 呈正相关（MD=16.0 计数/分钟；95%CI=13.1 至 18.8，p<0.001），与久坐时间呈负相关（MD=-0.5%；95%CI=-0.6 至-0.4，p<0.001）。在按活动状态分层后，GMFM 和 PEDI 与活动参与者的 HPA 和久坐时间相关，但与非活动参与者无关。
在 4-5 岁能走动的 CP 儿童中，粗大运动能力和运动能力与 HPA 和久坐时间有关。
