关于一个人是否超重的决定通常是通过查看身高和体重表来获得的，这些表需要了解性别，身高和身体框架尺寸来确定理想体重。这些表格受到了批评，因为它们没有包括一个客观的程序来确定身体框架大小（1，3）。1983年的《大都市身高和体重表》通过为个人提供一种估计身体框架尺寸的客观方法，解决了Tkis缺乏问题。然而，最近大众媒体对1983年表格的介绍并不包括推荐的确定身体框架尺寸的程序。看来，人们将继续作出主观判断，他们的身体框架大小时，确定他们的理想体重与这些表。这项研究评估了人们在没有客观测量手段的情况下估计身体框架尺寸的准确性。研究对象为85名在当地一家购物中心购物的人。45名男性，平均年龄30岁。(SD= 13.66岁）女性40例，平均年龄31岁。(SD= 16.55岁）他们被要求通过检查1983年的大都会身高和体重表来选择他们的理想体重。他们的选择为研究人员提供了对受试者身体尺寸的主观评估。然后，通过在桡骨和尺骨茎突远端的手腕最小周长周围放置软卷尺，客观评估受试者的身体框架尺寸，这是Lindner开发的程序（2）。结果表明，只有32的85名受试者正确估计身体框架的大小。当根据性别对数据进行检查时，45名男性中有18名和40名女性中有14名的回答符合Linder标准。在40名男性和18名女性中，他们的数据可能低估了身体的尺寸，即，那些客观确定的中等和大的身体框架尺寸的受试者中，57%的男性和61%的女性低估了他们的身体框架尺寸。由于低估身体的尺寸可能会导致人们相信他们超重，而事实上他们可能并不超重，这里观察到的低估的发生率可能有助于解释调查，这些调查产生了比客观估计更高的主观感觉“太胖”的发生率。
A decision as to whether one is overweight is usually obtained by looking at height and weight tables which require a knowledge of sex, height, and body-frame size to determine ideal weight. These tables have been criticized because they have not included an objective procedure for determining body-frame size (1, 3). Tkis lack has been addressed in the 1983 Metropolitan Height and Weight tables by providing individuals with an objective means of estimating body-frame size. Recent mass media presentations of the 1983 tables, however, do not include the recommended procedure for determining body-frame size. It appears that people will continue to make subjective judgments regarding their body-frame size when determining their ideal weights with these tables. This study assessed the accuracy with which people estimate body-frame size when they are not provided an objective means of measurement. Subjects were 85 individuals recmited at a local shopping mall. Forty-five men with a mean age of 30 yr. (SD = 13.66 yr.) and 40 women with a mean age of 31 yr. (SD = 16.55 yr.) were asked to select their ideal weight by examining the 1983 Metropolitan Height and Weight tables. Their selections ~rovided the researchers with a subiective assessment of the subjects' body-frame size. The subjects were then objectively assessed for body-frame size by placing a soft measuring tape around the smallest circumference of the wrist, distal to styloid process of radius and ulna, a procedure developed by Lindner (2). Results indicated only 32 of 85 subjects correctly estimated body-frame size. When the data were examined according to sex, responses of 18 of 45 men and of 14 of 40 women agreed with the Linder criterion. Of the 40 men and 18 women whose data made it possible to underestimate body-frame size, i.e., those subjects with objectively determined medium and large body-frame sizes, 57% of the men and 61% of the women underestimated their body-frame size. As underestimating body-frame size may lead people to believe they are overweight when in fact they may not be, the incidence of underestimating observed here may help explain surveys which yield a much higher incidence of subjective feelings of being "too fat" than would be warranted by objective estimates.
