Questionnaire surveys suggest physical activity levels in children are low, particularly among children from deprived areas. Using accelerometers, it was found that children from a deprived inner city school were active at recommended levels and had similar levels of activity to children in other studies from more affluent populations. However, this finding was dependent on the threshold used to define moderate activity.
问卷调查表明，儿童的身体活动水平较低，在贫困地区的儿童中尤为明显。使用加速度计发现，来自市中心贫困学校的儿童达到了建议的活动水平，并且与其他来自更富裕人群的研究中的儿童活动水平相似。然而，这一发现取决于用于定义适度活动的阈值。
