自我报告的体重和身高可能会受到性别，社会经济和其他偏见的影响。另一方面，获得测量的人体测量数据可能会给答卷人造成很大负担。西雅图肥胖研究II（SOS II）参与者（n = 419）通过访谈辅助行为调查提供了自我报告的身高、体重和人口统计学数据。然后由经过培训的工作人员对参与者进行称重和测量。整个过程在12个月后重复。在后续访问中，参与者还被要求回忆他们12个月前的体重。使用Bland-Altman图评估测量数据和自我报告数据之间的一致性。观察到一些肥胖个体的体重低报。性别或社会经济地位（SES）不影响自我报告。Bland-Altman图提供了体重（kg）的95%一致性限度为−3.13至5.83，BMI（kg/m2）的95%一致性限度为1.21至2.52。测量和自我报告的BMI类别之间的一致性非常好（男性Kappa = 0.82，女性为0.86）。在随访时，参与者估计他们12个月前的体重比他们现在的体重更准确。自我报告的身高和体重在两个时间点与客观测量高度相关。没有观察到性别或SES偏见。在肥胖参与者中观察到轻微但具有统计学意义的漏报（<1.5 kg）。在肥胖人群中使用自我报告的数据时应谨慎。本文的在线版本（doi：10.1186/s40608-016-0088-2）包含补充材料，可供授权用户使用。
Self-reported weights and heights can be subject to gender, socio-economic, and other biases. On the other hand, obtaining measured anthropometric data can pose a significant respondent burden. Seattle Obesity Study II (SOS II) participants (n = 419) provided self-reported height, weight, and demographic data through an interviewer-assisted behavior survey. Participants were then weighed and measured by trained staff. The entire process was repeated 12 months later. At the follow up visit, participants were also asked to recall their weight from 12 months ago. The concordance between measured and self-reported data was assessed using Bland-Altman plots. Some weight underreporting by obese individuals was observed. Gender or socio-economic status (SES) did not affect self-reports. Bland-Altman plots provided 95 % limits of agreement of −3.13 to 5.83 for weight (kg), and 1.21 to 2.52 for BMI (kg/m2). The concordance between measured and self-reported BMI categories was excellent (Kappa = 0.82 for men, and 0.86 for women). At the follow up visit, participants estimated their weight 12 months ago more accurately than their current weight. Self-reported heights and weights were highly correlated with objective measures at two points in time. No gender or SES biases were observed. Minor, yet statistically significant under-reporting (<1.5 kg) was observed for obese participants. Caution should be used when using self-reported data in obese populations.
