The purpose of this study was to compare objectively measured physical activity (PA) and parent-reported assessments of the children's PA in an overweight/obese child sample. A total of 67 child-parent dyads were recruited for study participation. Child anthropometric measures and parent-reported questionnaires were completed, and then PA was measured by accelerometers for 48 consecutive hours. These children demonstrated moderate-to-vigorous PA for 17.32 min per day on average. The children spent 86.7% of their time in sedentary activities. Parents' reports of hyperactivity were significantly related to the objectively measured PA; however, the parents significantly overestimated the average amount of time children spent in each activity level. These findings suggest that although parents may be able to generally characterize their child's PA, they may not be able to accurately report specific information and thus may struggle to identify clear activity goals for their child and/or be unable to assess intervention effects.
本研究的目的是比较超重/肥胖儿童样本中客观测量的身体活动（PA）与家长报告的儿童PA评估情况。总共招募了67对儿童-家长二元组参与研究。完成了儿童人体测量指标和家长报告的问卷，然后用加速度计连续48小时测量PA。这些儿童平均每天进行中等到剧烈强度PA的时间为17.32分钟。这些儿童86.7%的时间都处于久坐活动中。家长报告的多动情况与客观测量的PA显著相关；然而，家长显著高估了儿童在每个活动水平上花费的平均时间。这些发现表明，尽管家长可能总体上能够描述其孩子的PA情况，但他们可能无法准确报告具体信息，因此可能难以确定孩子明确的活动目标和/或无法评估干预效果。
