Assessing young children's physical activity and sedentary behavior can be challenging and costly. This study aimed to assess the validity of a brief survey about activity preferences as a proxy of physical activity and of a 7-day activity diary, both completed by the parents and using accelerometers as a reference measure. Thirty-four parents and their children (aged 3-5 years) who attended childcare centers in Sydney (Australia) were recruited for the study. Parents were asked to complete a 9-item brief survey about activity preferences of their child and a 7-day diary recording the child's physical activity and sedentary behaviors. Both measures were compared with accelerometer data collected from the child over the same period as the diary survey. The findings suggest that parent completed diaries have acceptable correlation coefficients with accelerometer measures and could be considered in future research assessing physical activity and sedentary behavior of children aged 3-5 years.
评估幼儿的身体活动和久坐行为具有挑战性且成本高昂。本研究旨在评估一份关于活动偏好的简短调查问卷作为身体活动替代指标的有效性，以及一份由家长填写的7天活动日记的有效性，并将加速度计作为参考测量工具。招募了34名在悉尼（澳大利亚）参加儿童保育中心的家长及其3至5岁的孩子参与该研究。要求家长完成一份关于孩子活动偏好的9项简短调查问卷，以及一份记录孩子身体活动和久坐行为的7天日记。将这两种测量方法与在与日记调查同期从孩子身上收集的加速度计数据进行比较。研究结果表明，家长填写的日记与加速度计测量结果具有可接受的相关系数，在未来评估3至5岁儿童身体活动和久坐行为的研究中可以考虑使用。
