“…There are some investigations on the differences between self-reported and directly measured height and weight. Mable et al (1988) described that the report in the body image questionnaire was highly reliable for the college students, while Nishizawa et al (2002) found that self-reported values slightly underestimated the actual weight in the junior and senior high school students. Meanwhile, the boundary weights proposed here are easily changeable in connection with the calculation, which depends on percentages of essential fat.…”

The present study is aimed to clarify the degree of leanness desired by contemporary young Japanese women using questionnaires and to use allometry to define the body weight boundary between the excessively lean and the others for a given height. Questionnaires on ideal body shape were distributed to female college students living in Akita and the suburbs of Tokyo. Data for 578 respondents, aged 18 to 21 years-old, were analyzed. The questionnaire asked the subjects to report their current and ideal body shape and to make a qualitative self-assessment of their weight. On average, the perceived ideal weight was 5.2 kg lower than the current weight. The results also revealed that young women have a tendency to misunderstand their body shape and to regard themselves as heavier than they really were. Meanwhile, we defined leanness as a state of insufficient lean body mass (LBM, kg) in relation to height (Ht, cm). Allometric equation of LBM on Ht and the standard error of estimate (SEE) were calculated as LBMϭ3.87ϫ10 Ϫ3 ϫHt 1.826 and 1.09, respectively. The LBM boundary between the excessively lean and the others was determined using these values according to a statistical procedure comparing normal and abnormal values. The corresponding total body weight was estimated from the boundary LBM in the literature. Subsequently the body weight boundary for each height was tabulated in order to make young women reconsider weight control. The subjects were asked to assess the body weight boundary for their own height. The boundary values were found to be consistent with the sense of the subjects.

OBJECTIVE: Information about the accuracy of family informant estimates of height and weight should assist investigators in evaluating the costs and bene®ts of using this type of data in genetic study designs. DESIGN AND METHOD: To assess the accuracy of family informant estimates, 374 ®rst-degree relatives from 94 Caucasian families, gave estimates about the heights and weights of their ®rst degree relatives. These estimates were compared with measured heights and weights to determine their accuracy. RESULTS: Informant estimates were highly predictive of measured heights (r 0.95), and weights (r 0.94), but informants systematically overestimated heights (mean 1.4 cm) and underestimated weights of their family members (mean 4.1 kg). CONCLUSIONS: On average, height estimates were generally within 1% of the measured height and weight estimates were within 3 ± 5% of the measured weight. Therefore, these proxy measures can provide useful data, when measured or self-reported heights and weights are not available.
