尽管人们普遍认为体力活动是健康的重要决定因素，但评估这种复杂的行为是一项相当大的挑战。本次系统回顾和荟萃分析的目的是检查、量化和报告当前的证据状态，以证明最近组合传感 Fitbit 测量的能量消耗、心率和步数的有效性。我们根据能量消耗、心率和步数的参考指标，对组合传感 Fitbit 的验证研究进行了系统回顾和 Bland-Altman 荟萃分析。系统评价共纳入 52 项研究。在 52 项研究中，有 41 项 (79%) 被纳入荟萃分析，代表 Fitbit 设备与标准测量之间的 203 项个体比较（即，n=117，心率为 57.6%；n=49，能量消耗为 24.1%；n=37，步数为 18.2%）。总体而言，纳入研究的大多数作者得出的结论是，与标准测量相比，最新的 Fitbit 模型低估了心率、能量消耗和步数。这些独 对于心率、能量消耗和步数：分别为-23.99至18.01、-12.75至7.41和-13.07至6.86）。 Fitbit 设备可能会低估心率、能量消耗和步数。这些测量值的估计因研究质量、参与者年龄、活动类型和 Fitbit 型号而异。大多数研究的定性结论与荟萃分析的结果一致。尽管预期的准确度可能因环境而异，但平均而言，对于步数和心率而言，这种低估是可以接受的。然而，出于某些研究目的，能量消耗的测量可能不准确。
Although it is widely recognized that physical activity is an important determinant of health, assessing this complex behavior is a considerable challenge. The purpose of this systematic review and meta-analysis is to examine, quantify, and report the current state of evidence for the validity of energy expenditure, heart rate, and steps measured by recent combined-sensing Fitbits. We conducted a systematic review and Bland-Altman meta-analysis of validation studies of combined-sensing Fitbits against reference measures of energy expenditure, heart rate, and steps. A total of 52 studies were included in the systematic review. Among the 52 studies, 41 (79%) were included in the meta-analysis, representing 203 individual comparisons between Fitbit devices and a criterion measure (ie, n=117, 57.6% for heart rate; n=49, 24.1% for energy expenditure; and n=37, 18.2% for steps). Overall, most authors of the included studies concluded that recent Fitbit models underestimate heart rate, energy expenditure, and steps compared with criterion measures. These independent conclusions aligned with the results of the pooled meta-analyses showing an average underestimation of −2.99 beats per minute (k comparison=74), −2.77 kcal per minute (k comparison=29), and −3.11 steps per minute (k comparison=19), respectively, of the Fitbit compared with the criterion measure (results obtained after removing the high risk of bias studies; population limit of agreements for heart rate, energy expenditure, and steps: −23.99 to 18.01, −12.75 to 7.41, and −13.07 to 6.86, respectively). Fitbit devices are likely to underestimate heart rate, energy expenditure, and steps. The estimation of these measurements varied by the quality of the study, age of the participants, type of activities, and the model of Fitbit. The qualitative conclusions of most studies aligned with the results of the meta-analysis. Although the expected level of accuracy might vary from one context to another, this underestimation can be acceptable, on average, for steps and heart rate. However, the measurement of energy expenditure may be inaccurate for some research purposes.
