目的：检验1997年新南威尔士州健康调查（NSW Health Survey 1997）中通过电话报告的自我报告身高和体重数据的有效性，并确定其在人口调查中监测超重和肥胖的准确性。方法：收集了227名居住在西悉尼的参加1997年新南威尔士州健康调查的人的自我报告和测量身高和体重。自我报告（SR）的体重和身高导致基于测量的体重和身高的相对体重状态（BMI）的错误分类，分类62%的男性和47%的女性超重或肥胖，相比之下，分别为39%和32%，从自我report.Conclusions解释SR身高和体重数据时应谨慎使用，因为BMI从这些很可能低估超重和肥胖的真实患病率。SR数据在营养监测中占有一席之地，因为它们相对便宜且易于收集，但是，根据公认的分界点将人分为体重类别，使用SR身高和体重会产生不准确的流行率估计。需要定期对SR高度和权重的有效性进行子研究，以表明SR有效性的变化程度。
Objective:To examine the validity of self-reported height and weight data reported over the telephone In the 1997 NSW Health Survey, and to determine its accuracy to monitor overweight and obesity in population surveys.Method: Self-reported and measured heights and weights were collected from 227 people living in Western Sydney, who had participated in the NSW Health Survey 1997.Results: Self-reported (SR) weights and heights led to misclassification of relative weight status, BMI, based on measured weights and heights, classified 62% of males and 47% of females as overweight or obese, compared with 39% and 32%, respectively, from self-report.Conclusions Caution should be used when interpreting SR height and weight data from surveys, because BMI derived from these is likely to underestimate the true prevalence of overweight and obesity.Implications: SR data have a place in nutrition monitoring because they are relatively inexpensive and easy to collect. However, classifying people into weight categories on the basis of accepted cutpoints, using SR heights and weights yields inaccurate prevalence estimates. Periodic sub-studies of the validity of SR heights and weights are needed to indicate the extent to which the validity of SR is changing.
