Participation in regular physical activity (PA) provides health, psychological, and physiological benefits for people with and without a physical disability. This study investigated the physical and sedentary activity patterns of adolescents with cerebral palsy (CP). A cross-sectional, descriptive, postal survey was used, consisting of the Physical Activity Questionnaire for Adolescents (PAQ-A), self-reported level of gross motor function (based on the Gross Motor Function Classification System [GMFCS]), and specific questions regarding weekly sedentary activities. Following piloting to determine test-retest reliability (intraclass correlation [ICC] for PA=0.90; total weekly sedentary time=0.84) and concurrent validity (survey PA score vs pedometry, Pearson's r=0.24; survey PA score vs accelerometry, r=-0.21; survey weekly sedentary time vs logbook, r=0.38), the survey was mailed to all adolescents with CP in South Australia registered with Novita Children's Services (n=219). One hundred and twelve valid surveys were returned (76 males, 36 females; age range 11-17y, mean age 13y 11mo [SD 23mo]; GMFCS Level I, n=42; Level II, n=27; Level III, n=10; Level IV, n=17; Level V, n=15; level not reported, n=1). Results were compared with recent normative age- and sex-matched data sets. Key findings were that PA level of adolescents with CP was related to level of gross motor function and inversely related to age, and that adolescents with CP were less physically active than their peers without disability. Comparisons with normative data sets suggested that adolescents with CP tend to participate in less structured and lower intensity PA compared with non-disabled adolescents, though sedentary activity patterns (TV and computer use) of adolescents with and without CP were similar.
参与定期体育活动（PA）对有身体残疾和无身体残疾的人都有健康、心理和生理益处。本研究调查了脑瘫（CP）青少年的身体活动和久坐行为模式。采用了一项横断面描述性邮寄调查，包括青少年身体活动问卷（PAQ - A）、自我报告的粗大运动功能水平（基于粗大运动功能分类系统[GMFCS]）以及关于每周久坐活动的具体问题。在进行预试验以确定重测信度（PA的组内相关系数[ICC]=0.90；每周总久坐时间=0.84）和同时效度（调查PA得分与计步器测量结果对比，Pearson相关系数r = 0.24；调查PA得分与加速度计测量结果对比，r = -0.21；调查每周久坐时间与日志对比，r = 0.38）之后，该调查问卷被邮寄给在南澳大利亚州诺维塔儿童服务机构登记的所有CP青少年（n = 219）。共返回112份有效问卷（男性76名，女性36名；年龄范围11 - 17岁，平均年龄13岁11个月[标准差23个月]；GMFCS I级，n = 42；II级，n = 27；III级，n = 10；IV级，n = 17；V级，n = 15；未报告级别，n = 1）。研究结果与近期按年龄和性别匹配的标准数据集进行了比较。主要发现是，CP青少年的PA水平与粗大运动功能水平相关，与年龄呈负相关，并且CP青少年的身体活动比其无残疾的同龄人少。与标准数据集的比较表明，与非残疾青少年相比，CP青少年倾向于参与结构化程度较低、强度较小的PA，不过有CP和无CP青少年的久坐行为模式（看电视和使用电脑）相似。
