Self-reported height measures are increasingly being included in large-scale surveys in order to measure BMI. There have been concerns about the validity of self-reported measures but there remains little understanding of why respondents may not give accurate height reports. We examine whether a lack of knowledge could be a contributing factor, by investigating the reliability of self-reported height over time and across countries. We use longitudinal data from four large-scale longitudinal surveys conducted in Australia, United States, United Kingdom, and Europe (14 countries) where survey respondents were asked to report their height over multiple time periods to measure the extent of consistency of height reports across time. The overall level of inconsistent reporting of height is largest in Australia and Europe. Individuals with lower levels of education were significantly more likely to give two height reports that differed by 5 cm or more. Across all countries, inconsistent reporting with large height differences between waves was also more common among those in older populations. The findings point to subgroups of the population exhibiting a lack of knowledge regarding their own height.
为了测量体重指数（BMI），自我报告的身高测量越来越多地被纳入大规模调查中。人们一直担心自我报告测量的有效性，但对于受访者为何可能不给出准确的身高报告，仍然了解甚少。我们通过调查自我报告身高随时间和不同国家的可靠性，来检验知识欠缺是否可能是一个促成因素。我们使用了在澳大利亚、美国、英国和欧洲（14个国家）进行的四项大规模纵向调查的纵向数据，这些调查要求受访者在多个时间段报告他们的身高，以衡量身高报告随时间的一致程度。身高报告不一致的总体水平在澳大利亚和欧洲最高。受教育程度较低的个体给出相差5厘米或更多的两次身高报告的可能性显著更高。在所有国家中，不同调查波次间身高差异较大的不一致报告在老年人群体中也更为常见。研究结果表明，部分人群对自己的身高缺乏了解。
