Participation in physical activities is positively associated with better quality of life in children with cerebral palsy (CP). The objective of this study was to elucidate the relationship between the intensity of habitual physical activity (HPA) measured with an accelerometer and health-related quality of life (HRQOL) in school-age children with CP.
A secondary analysis of the cross-sectional data of 46 ambulatory children with CP was conducted. The participants wore an accelerometer for seven days to measure HPA: activity counts (counts/min) and physical activity energy expenditure (PAEE, kcal/kg/day), as well as %moderate-to-vigorous intensity physical activity (%MVPA), %light intensity physical activity (%LPA), and %sedentary physical activity (%SPA) were measured. Pediatric Quality of Life Inventory (PedsQL) 4.0 Generic Core Scales and Child Health Questionnaire Parent Form 50 Questions (CHQ-PF50) were used to measure HRQOL. A Pearson analysis and a hierarchical regression analysis were performed.
PAEE significantly predicted the results of the PedsQL(child) physical domain (β = 0.579, = 0.030), PedsQL(child) emotional domain (β = 0.570, = 0.037), PedsQL(child) social domain (β = 0.527, = 0.043), and PedsQL(child) total (β = 0.626, = 0.017). However, other HPA parameters could not predict any other HRQOL.
PAEE could be used as a biomarker in studies on HRQOL and HPA in ambulatory school-age children with CP.
参与体育活动与脑瘫（CP）患儿更好的生活质量呈正相关。本研究的目的是阐明用加速度计测量的习惯性身体活动（HPA）强度与学龄期CP患儿健康相关生活质量（HRQOL）之间的关系。
对46名能行走的CP患儿的横断面数据进行二次分析。参与者佩戴加速度计7天以测量HPA：活动计数（计数/分钟）和身体活动能量消耗（PAEE，千卡/千克/天），以及测量中度至剧烈强度身体活动百分比（%MVPA）、轻度强度身体活动百分比（%LPA）和久坐身体活动百分比（%SPA）。使用儿童生活质量量表（PedsQL）4.0通用核心量表和儿童健康问卷家长版50题（CHQ-PF50）来测量HRQOL。进行了Pearson分析和分层回归分析。
PAEE显著预测了PedsQL（儿童）身体领域（β = 0.579，P = 0.030）、PedsQL（儿童）情感领域（β = 0.570，P = 0.037）、PedsQL（儿童）社会领域（β = 0.527，P = 0.043）和PedsQL（儿童）总分（β = 0.626，P = 0.017）的结果。然而，其他HPA参数无法预测任何其他HRQOL。
PAEE可作为研究能行走的学龄期CP患儿HRQOL和HPA的生物标志物。
