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.
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.
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.
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.
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 cut-points, 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.
检验1997年新南威尔士州健康调查中通过电话报告的身高和体重数据的有效性，并确定其在人群调查中监测超重和肥胖情况的准确性。
从227名居住在悉尼西部且参与了1997年新南威尔士州健康调查的人员中收集自我报告的身高和体重以及测量的身高和体重。
自我报告的体重和身高导致相对体重状况的错误分类。基于测量的体重和身高计算的BMI将62%的男性和47%的女性归类为超重或肥胖，而自我报告的相应比例分别为39%和32%。
在解释调查中的自我报告身高和体重数据时应谨慎小心，因为由此得出的BMI可能会低估超重和肥胖的真实患病率。
自我报告数据在营养监测中有一席之地，因为它们相对便宜且易于收集。然而，使用自我报告的身高和体重，根据公认的切点将人们分类到体重类别中，会得出不准确的患病率估计。需要定期对自我报告身高和体重的有效性进行子研究，以表明自我报告有效性的变化程度。
