To explore the relationship between self-reported weight and height to actual weight and height in older Australian adolescents.
Weights and heights of 572 adolescents aged 15-19 years who participated in the 1995 Australian National Health Survey (NHS) and National Nutrition Survey (NNS) were examined.
Self-reported heights were significantly higher than measured heights in participants. There were no differences in the accuracy of self-reported heights among the adolescents by gender. Self-reported weights were significantly lower than measured weights among both boys and girls (p < 0.01). There were no differences in the accuracy of self-reported weights among the boys and girls. Differences between actual weight and self-reported weight were significantly greater for overweight or obese adolescents compared with normal/underweight adolescents (p < 0.01). The use of self-reported weight and height resulted in the correct classification of overweight or obesity in 69% boys and 70% of girls.
There was no significant gender difference in reporting weight and height in older adolescents. Bias in reporting weight and height was much higher in overweight or obese adolescents than normal/underweight adolescents.
The percentage of misclassification of overweight or obesity from self-reported data in this study was 31% for boys and 30% for girls, respectively. Therefore, the self-reported weight and height of older adolescents needs to be more cautiously utilised. Efforts to improve the accuracy of self-reporting in older adolescents are needed if this measure is to be reliable.
探讨澳大利亚大龄青少年自我报告的体重和身高与实际体重和身高之间的关系。
对572名年龄在15 - 19岁、参加了1995年澳大利亚全国健康调查（NHS）和全国营养调查（NNS）的青少年的体重和身高进行了检查。
参与者自我报告的身高显著高于测量身高。青少年中，按性别划分，自我报告身高的准确性没有差异。男孩和女孩自我报告的体重均显著低于测量体重（p < 0.01）。男孩和女孩在自我报告体重的准确性方面没有差异。与正常/体重过轻的青少年相比，超重或肥胖青少年的实际体重与自我报告体重之间的差异显著更大（p < 0.01）。使用自我报告的体重和身高，69%的男孩和70%的女孩超重或肥胖被正确分类。
大龄青少年在报告体重和身高方面没有显著的性别差异。超重或肥胖青少年报告体重和身高的偏差远高于正常/体重过轻的青少年。
本研究中，男孩和女孩自我报告数据中超重或肥胖误分类的百分比分别为31%和30%。因此，大龄青少年自我报告的体重和身高需要更谨慎地使用。如果要使这一测量可靠，就需要努力提高大龄青少年自我报告的准确性。
