背景在无法获得客观测量数据的研究中，使用自我报告的体重和身高来计算体重指数。关于老年人自我报告和测量的体重和身高之间的关联知之甚少。在威斯康星州的一个农村县，参加集体和家庭送餐计划的人在一份问卷上记录了他们的身高和体重，这是营养风险和生活质量研究的一部分。在同一天进行身高和体重的客观测量。对131名年龄在62-92岁之间的受试者的数据进行分析，以评估自我报告和测量的体重和身高之间的关联。自我报告和测量值之间的相关系数表明，自我报告的体重比自我报告的身高在这一人群中更有效。然而，20%的样本中自我报告的体重被误报了10磅或更多。需要更多的数据来评估自我报告的体重和身高数据在老年人群体中的效用。从这项研究来看，自我报告的身高和体重数据，如果用于老年人，应该只作为连续变量，而不是将受试者分为相对体重类别。
Background. Self-reported weight and height are used to compute ponderal indices in studies where it is impractical to obtain objectively measured data. Little is known about the associations between self-reported and measured weight and height in older adults.Methods. Participants in congregate and home-delivered meal programs in a rural Wisconsin county recorded their height and weight on a questionnaire as part of a study on nutritional risk and quality of life. Objective measurements of height and weight were made on the same day. Data for 131 subjects, ranging in age from 62-92 years, were analyzed to evaluate associations between self-reported and measured weights and heights.Results. Correlation coefficients between self-reported and measured values suggested that self-reported weight was somewhat more valid than self-reported height in this population. However, self-reported weight was misreported by 10 pounds or more in 20% of the sample.Conclusions. More data are needed to evaluate the utility of self-reported data for weight and height in groups of older people. Judging from this study, self-reported height and weight data, if used at all for older adults, should only be used as it continuous variable rather than for classifying subjects into relative weight categories.
