Abstract

Abstract: Objective To measure physical activity in children with cerebral palsy(CP),and to analyze the relevant factors,in order to provide scientific reference for clinical treatment.Methods Totally 98 CP children aged 2 to 12 years in Shenzhen Children′s Hospital were enrolled in this study from June 2017 to June 2018. The daily activity of the participants was recorded by accelerometers,and the results were compared with the recommendation standard for physical activity of Chinese children and adolescents. And the influences of gender,age and gross motor function classification system(GMFCS) on physical activity were ananlyzed. Results The average time of daily sedentary behavior of CP children was(470.73±107.21) min,and daily moderate-to-vigorous physical activity(MVPA) was(40.65±19.05) min. The time for sedentary activity in boys was significantly longer than that of girls(P＜0.05). Compared with other age groups,the time for sedentary behavior of CP children aged 4 to 6 years was the least,while the time for MVPA was the most(P＜0.001). The GMFCS level was negatively correlated with sedentary activity time,and positively related to MVPA time(P＜0.001).Conclusions Physical activity in CP children is significantly lower than the recommended level. Gender,age and GMFCS level are highly correlated with physical activity in CP children. So it is supposed to help CP children reduce sedentary behavior and increase moderate-to-vigorous physical activity in many ways.

摘要： 目的了解脑瘫儿童的身体活动水平及其影响因素,为临床治疗提供科学依据。方法选取2017年6月—2018年6月在深圳市儿童医院就诊的2～12岁脑瘫儿童98例,采用加速度计步器测量其身体活动水平,与中国儿童青少年身体活动指南推荐标准进行比较,分析性别、年龄及运动功能对身体活动的影响。结果脑瘫儿童平均每天静坐时间为(470.73±107.21)min,中高强度身体活动时间为(40.65±19.05)min。男童较女童的静坐时间更少(P＜0.05);与其它年龄组相比,4～6岁组CP儿童的静坐时间最少,中高强度身体活动(MVPA)最多(P＜0.05);粗大运动功能分级(GMFCS)级别越低,静坐时间越多、MVPA越少(P＜0.001)。结论脑瘫儿童的身体活动水平明显低于指南推荐水平,性别、年龄及GMFCS分级是其影响因素。应从多方面促进和引导脑瘫儿童减少静坐行为,增加中高强度身体活动。
