关于体重史的数据可能会提高肥胖健康风险流行病学模型的预测有效性，但收集这些数据往往是不可行的。在这项研究中，我们调查的有效性的总结措施的重量历史。我们使用健康与退休研究的数据评估了50-84岁成年人样本中最大体重报告的质量。将基于2004年回忆体重的回忆最大体重指数（BMI，以kg/m2测量）与基于1992年至2004年期间每两年收集的自我报告体重计算的最大BMI进行比较。Logistic回归用于评估预测流行状况的措施之间的相似性。总体样本中回忆的最大体重与计算的最大体重之间的相关系数为0.95。在91.4%的时间内，回忆的最大BMI值在计算值的3个BMI单位内。使用回忆值，肥胖I（BMI 30.0-34.9）、肥胖II（35.0-39.9）和肥胖III（40.0及以上）的个体比例分别为28.8%、12.7%和6.6%，而使用计算值，分别为27.1%、10.5%和4.9%。在多变量分析中，两种BMI指标在许多慢性疾病中预测疾病患病率相似。回忆的最大BMI与回忆前12年计算的最大BMI密切相关，表明该指标可作为近期体重状况的可靠汇总指标。
Data on weight history may enhance the predictive validity of epidemiological models of the health risks of obesity but collecting such data is often not feasible. In this study, we investigate the validity of a summary measure of weight history. We evaluated the quality of reporting of maximum weight in a sample of adults ages 50-84 using data from the Health and Retirement Study. Recalled max body mass index (BMI, measured in kg/m2) based on recalled weight in 2004 was compared to calculated max BMI based on self-reported weight collected biennially between 1992 and 2004. Logistic regression was used to assess similarity between the measures in predicting prevalent conditions. The correlation coefficient between recalled and calculated max weight in the overall sample was 0.95. Recalled max BMI value was within 3 BMI units of the calculated value 91.4% of the time. The proportion of individuals obese I (BMI 30.0-34.9), obese II (35.0-39.9) and obese III (40.0 and above) were 28.8%, 12.7% and 6.6% using recalled values compared to 27.1%, 10.5% and 4.9% using calculated values. In multivariate analyses, the two BMI measures similarly predicted disease prevalence across a number of chronic conditions. Recalled max BMI was strongly correlated with max BMI calculated over the twelve year period prior to recall, suggesting that this measure can serve as a reliable summary measure of recent weight status.
