The high rate of delayed recidivism seen in behavioral weight loss studies makes follow-up over a number of years essential. Unfortunately, these data are both expensive and difficult to collect. This report examines the validity of body weights routinely recorded in medical charts and their usefulness in the long-term evaluation of weight control programs. Comparison of 123 pairs of chart weights and research clinic weights recorded within 30 days of each other showed a mean difference of .06 lb (.03 kg) and a standard deviation of 2.38 lb (1.08 kg). This measurement error is considerably less than that seen in self-reported weights of obese adults. The accuracy, economy and relative ease of collection make the use of medical chart weights well suited for long-term evaluations of weight loss studies and other research purposes.
行为减肥研究中出现的高延迟复发率使得数年的随访至关重要。不幸的是，这些数据既昂贵又难以收集。本报告研究了医学图表中常规记录的体重的有效性及其在体重控制项目长期评估中的作用。对123对在彼此30天内记录的图表体重和研究诊所体重进行比较，结果显示平均差异为0.06磅（0.03千克），标准差为2.38磅（1.08千克）。这种测量误差远小于肥胖成年人自我报告体重中所见的误差。医学图表体重的准确性、经济性和相对容易收集性使其非常适合用于减肥研究的长期评估和其他研究目的。
