需要准确的评估工具来监测身体活动（PA）水平和评估干预措施的效果。此外，提高对PA的认识往往被用作务实行为干预的第一步，因为个人认为他们所做的活动量与实际进行的活动量之间的差异可能会成为改变的障碍。以前的研究已经证明，与用加速度计测量的身体活动水平相比，个人报告的活动量存在差异。了解那些PA水平排名不同的人的特征是很重要的，因为它可以为未来的研究提供工具的选择。该项目的目的是确定哪些个体特征与自我报告和加速度计测量的身体活动之间的差异相关。参与者数据来自2009年剑桥通勤与健康研究。自我报告和加速度计测量的PA的四分位数是通过将每个测量从最低到最高进行排名而得出的。这些四分位数进行比较，以确定是否个人的身体活动排名较高的任何一种方法。多项逻辑回归模型被用来调查与不同类别的错配相关的个体特征。来自486名参与者（70%为女性）的数据被纳入分析。在校正分析中，超重或肥胖个体的身体活动通过自我报告比通过加速度计显著更可能比正常体重个体排名更高（OR = 2.07，95%CI = 1.28-3.34），特别是在女性中（OR = 3.97，95%CI = 2.11-7.47）。 在超重或肥胖的成年人中，自我报告和加速度计测量的身体活动水平之间不匹配的可能性更大。未来在超重或肥胖成人中的研究应考虑采用这两种测量方法。
Accurate assessment tools are required for the surveillance of physical activity (PA) levels and the assessment of the effect of interventions. In addition, increasing awareness of PA is often used as the first step in pragmatic behavioural interventions, as discrepancies between the amount of activity an individual perceives they do and the amount actually undertaken may act as a barrier to change. Previous research has demonstrated differences in the amount of activity individuals report doing, compared to their level of physical activity when measured with an accelerometer. Understanding the characteristics of those whose PA level is ranked differently when measured with either self-report or accelerometry is important as it may inform the choice of instrument for future research. The aim of this project was to determine which individual characteristics are associated with differences between self-reported and accelerometer measured physical activity. Participant data from the 2009 wave of the Commuting and Health in Cambridge study were used. Quartiles of self-reported and accelerometer-measured PA were derived by ranking each measure from lowest to highest. These quartiles were compared to determine whether individuals’ physical activity was ranked higher by either method. Multinomial logistic regression models were used to investigate the individual characteristics associated with different categories of mismatch. Data from 486 participants (70% female) were included in the analysis. In adjusted analyses, the physical activity of overweight or obese individuals was significantly more likely to be ranked higher by self-report than by accelerometer than that of normal-weight individuals (OR = 2.07, 95%CI = 1.28–3.34), particularly among women (OR = 3.97, 95%CI = 2.11–7.47). There was a greater likelihood of mismatch between self-reported and accelerometer measured physical activity levels in overweight or obese adults. Future studies in overweight or obese adults should consider employing both methods of measurement.
