本研究的目的是回顾加速度计的佩戴方法，以及加速度计与身体活动问卷数据之间的相关性，这取决于参与者的特征。我们纳入了57篇用加速度计和问卷法测量身体活动的文章。标准是至少有100名18岁以上的参与者，并有英文手稿。比较了加速度计磨损方法。评估问卷与加速度计之间的Spearman和Pearson相关系数，以及性别、年龄类别和体重指数（BMI）类别之间的差异。在大多数调查中，要求在醒着的时间内佩戴7天，设备大多系在臀部和腰带上。在大多数研究中，至少需要4天有效时间，每天至少佩戴10小时。在各个研究中，问卷总得分与加速度计测量值的相关性（r = Pearson, ρ = Spearman）在男性中为r = 0.08至ρ = 0.58 (P < 0.001)，在女性中为r = - 0.02至r = 0.49 （P < 0.01）。年龄≤65岁的参与者的总体力活动的相关性从r = 0.04到ρ = 0.47 (P < 0.001)，老年人（≥65岁）的相关性从r = 0.16 （P = 0.02）到r = 0.53 （P < 0.01）。很少有研究调查BMI分层，有不同的切点和不一致的结果。在男性自我报告的体力活动方面，加速度计提供的结果似乎更加一致。然而，由于整体的一致性有限，每种方法测量的方面不同，研究的维度也不同，建议研究同时使用问卷和加速度计来获得最完整的身体活动信息。本文的在线版本（doi:10.1186/s12889-016-3172-0）包含补充材料，可供授权用户使用。
The aim of this study is to review accelerometer wear methods and correlations between accelerometry and physical activity questionnaire data, depending on participant characteristics. We included 57 articles about physical activity measurement by accelerometry and questionnaires. Criteria were to have at least 100 participants of at least 18 years of age with manuscripts available in English. Accelerometer wear methods were compared. Spearman and Pearson correlation coefficients between questionnaires and accelerometers and differences between genders, age categories, and body mass index (BMI) categories were assessed. In most investigations, requested wear time was seven days during waking hours and devices were mostly attached on hips with waist belts. A minimum of four valid days with wear time of at least ten hours per day was required in most studies. Correlations (r = Pearson, ρ = Spearman) of total questionnaire scores against accelerometer measures across individual studies ranged from r = 0.08 to ρ = 0.58 (P < 0.001) for men and from r = −0.02 to r = 0.49 (P < 0.01) for women. Correlations for total physical activity among participants with ages ≤65 ranged from r = 0.04 to ρ = 0.47 (P < 0.001) and from r = 0.16 (P = 0.02) to r = 0.53 (P < 0.01) among the elderly (≥65 years). Few studies investigated stratification by BMI, with varying cut points and inconsistent results. Accelerometers appear to provide slightly more consistent results in relation to self-reported physical activity among men. Nevertheless, due to overall limited consistency, different aspects measured by each method, and differences in the dimensions studied, it is advised that studies use both questionnaires and accelerometers to gain the most complete physical activity information.
