Title: Comparison of Self-Reported Height and Weight with Measured Data: Secondary Analysis of the NHANES III Data

Abstract:

Estimation of height and weight is an important component of anthropometric assessment. Accurate measurement of these components, however, is not always possible. Often, researchers must gather self-reported data on height and weight and hope that most of the errors are stochastic. Our earlier paper compared the measured heights and weights from the third National Health And Nutrition Examination Survey (NHANES III) with self-reported data covering the same time from but collected from the annual National Health Interview Surveys (NHIS) from 1987 to 1993 (Hart and Tomazic, 1999). Our analysis indicated that inaccuracies existed both in the self-reported height and weight. Further, errors in height and weight reporting were evident across all age groups. However, this analysis, because it used two separate national surveys, could not compare what people report versus their actual measurements at an individual level. This limitation was overcome when the National Center for Health Statistics released more data from the NHANES III data collection that included self-reported data as well as the measured height and weight.
