To examine the relationship of physical activity (PA) and walking performance to QOL in ambulatory children with CP, as function is not consistently associated with QOL in this population.
A secondary analysis of a cross-sectional cohort of 128 ambulatory children with CP, ages 2.2-9.9 years and GMFCS levels I-III, was employed. Individual multivariate regression models were developed for physical, psychosocial, and total domains of QOL as measured by the Pediatric Quality of Life Inventory (PedsQL) controlling for physical activity and walking performance, participation level and frequency, topography of CP, walking capacity, age, and satisfaction with participation.
Physical, psychosocial and total QOL averaged 52.2, 60.9, and 56.5 respectively. PA was positively associated with physical (0.64, p < 0.01) and total QOL (0.54, p < 0.01). Walking performance was associated with physical QOL (0.16, p = 0.05), participation level was positively related to psychosocial (0.44, p < 0.01), and age negatively for all QOL domains (> -0.43, p < 0.01).
Physical activity, walking performance, and level of participation in daily life are associated with varying domains of QOL. Future work should explore factors that influence the relationship of daily physical/walking activity and participation to QOL in children with ambulatory CP as they age.
研究在能行走的脑瘫儿童中，身体活动（PA）和步行能力与生活质量（QOL）之间的关系，因为在这一人群中，功能与生活质量的关联并不一致。
对128名年龄在2.2 - 9.9岁、粗大运动功能分级系统（GMFCS）水平为I - III级的能行走的脑瘫儿童组成的横断面队列进行二次分析。针对生活质量的身体、心理社会和总体领域，采用个体多变量回归模型，这些领域通过儿童生活质量量表（PedsQL）进行测量，并对身体活动、步行能力、参与水平和频率、脑瘫类型、步行能力、年龄以及参与满意度进行控制。
身体、心理社会和总体生活质量的平均值分别为52.2、60.9和56.5。身体活动与身体生活质量（0.64，p < 0.01）和总体生活质量（0.54，p < 0.01）呈正相关。步行能力与身体生活质量相关（0.16，p = 0.05），参与水平与心理社会生活质量呈正相关（0.44，p < 0.01），年龄与所有生活质量领域呈负相关（> -0.43，p < 0.01）。
身体活动、步行能力和日常生活参与水平与生活质量的不同领域相关。未来的研究应探索随着年龄增长，影响能行走的脑瘫儿童日常身体/步行活动及参与与生活质量关系的因素。
