The validity of self-report weight and height as a surrogate method for direct measurement☆
Abstract
Bland-Altman analysis used to determine the extent of bias, agreement, and precision between self-report and the “gold standard” of actual weight and height measurement revealed significant discrepancies between methods. Use of self-report data by health care providers and researchers should be made based on the clinical situation, patient safety, and research goals.
