Objective methods are being used increasingly for the quantification of the amount of physical activity, intensity of physical activity and amount of sedentary behaviour in children. The accelerometer is currently the objective method of choice. In this review we address the advantages of objective measurement compared with more traditional subjective methods, notably the avoidance of bias, greater confidence in the amount of activity and sedentary behaviour measured, and improved ability to relate variation in physical activity and sedentary behaviour to variation in health outcomes. We also consider unresolved practical issues in paediatric accelerometry by critically reviewing the existing evidence and by providing new evidence.
客观方法越来越多地用于量化儿童的身体活动量、身体活动强度和久坐行为量。加速度计是目前首选的客观方法。在本综述中，我们阐述了与更传统的主观方法相比，客观测量的优势，特别是避免偏差、对所测量的活动量和久坐行为更有信心，以及将身体活动和久坐行为的变化与健康结果的变化联系起来的能力得到提高。我们还通过批判性地回顾现有证据并提供新证据，来探讨儿科加速度计中尚未解决的实际问题。
