1987-1989年回忆查尔斯顿心脏研究的参与者被要求报告他们目前的体重，并回忆他们在1984年和1960年的体重。将报告的体重与相应时间段内测量的体重进行比较。受试者包括年龄在62岁至100岁之间的男性和女性黑人和白人。所有受试者报告和测量的体重之间的相关性为0.979（当前）、0.935（4年）和0.822（28年回忆）。体重指数最低四分位数的受试者高估了自己的体重，而体重指数最高四分位数的受试者低估了自己的体重。这种趋势随着经过时间的增加而增加。随着认知测试成绩的下降，测量体重和报告体重之间的偏差也会增加。
Participants in the 1987-1989 recall of the Charleston Heart Study were asked to report their current weight and to recall their weight in 1984 and 1960. Reported weights were compared with weights measured in the respective time periods. Subjects included male and female blacks and whites between ages 62 and 100 years. Correlations between reported and measured weights over all subjects were 0.979 for current, 0.935 for 4-year, and 0.822 for 28-year recall. Subjects in the lowest body mass index quartile overestimated their weight, while subjects in the highest quartile underestimated their weight. This tendency increased as the elapsed time increased. Deviations between measured and reported weights increased as performance on cognitive tests declined.
