Validation study on self-reported height, weight, and blood pressure

Self-report data were compared with actual recorded data on height, weight, and blood pressure during health examinations to check for validity. The subjects were 1,823 persons, ages 40-68 years. Pearson correlations for systolic blood pressure, diastolic blood pressure, height, weight, and Body Mass Index between data reported in 1993 and measurements made in 1991 were .63, .60, .96, .96, and .92, respectively. Pearson correlations for the same variables between the data reported in 1993 and the measurements made in 1992 were .73, .67, .97, .97, and .94, respectively. Self-reported values for height, weight, and Body Mass Index appear to be valid over years or so.
