To objectively measure levels of physical activity in children, following treatment for acute lymphoblastic leukaemia (ALL).
Nineteen children who had completed treatment for ALL 6 months-5 years prior to study enrollment wore an accelerometer for 2 weekdays and 2 weekend days.
The children spent an average of 141 +/- 74 min/day engaged in moderate to vigorous physical activity (MVPA), an amount similar to that previously documented in healthy children. Only three of the 19 subjects averaged less MVPA than the recommended amount (at least 60 min/day). MVPA levels were significantly higher on weekdays than weekend days (P= 0.006). Overall, boys engaged in significantly more MVPA than girls (P= 0.029). MVPA time was negatively correlated with age (r =-0.80) and age at diagnosis (r =-0.87). No trend between MVPA and time off treatment or body mass index was identified.
Survivors of childhood ALL appear to be engaging in similar amounts of MVPA as those of the healthy children and are meeting recommended levels of physical activity.
客观测量急性淋巴细胞白血病（ALL）患儿治疗后的身体活动水平。
19名在入组研究前6个月至5年完成ALL治疗的儿童，在2个工作日和2个周末日佩戴加速度计。
这些儿童平均每天进行中度至剧烈身体活动（MVPA）的时间为141±74分钟，与之前记录的健康儿童的时间量相似。19名受试者中只有3人的MVPA平均量低于推荐量（至少60分钟/天）。工作日的MVPA水平显著高于周末（P = 0.006）。总体而言，男孩的MVPA显著多于女孩（P = 0.029）。MVPA时间与年龄（r = -0.80）和诊断时年龄（r = -0.87）呈负相关。未发现MVPA与治疗后时间或体重指数之间存在趋势。
儿童ALL幸存者的MVPA量似乎与健康儿童相似，且达到了推荐的身体活动水平。
