OBJECTIVES: To examine whether wheelchair users' self-reports of height and
weight differed significantly from direct measurements and whether weight
category classifications differed substantially when based on self-reported or
measured values. DESIGN: Single group, cross-sectional analysis. Analyses
included paired t tests, chi-square test, analysis of variance, and Bland-Altman
agreement analyses. SETTING: A university-based exercise lab. PARTICIPANTS:
Community-dwelling wheelchair users (N=125). INTERVENTIONS: Not applicable. MAIN
OUTCOME MEASURE: Participants' self-reported and measured height, weight, and
body mass index. RESULTS: Paired t tests revealed that there were significant
differences between wheelchair users' self-reported and measured values for
height (difference of 3.1+/-7.6cm [1.2+/-3.0in]), weight (-1.7+/-6.5kg
[-3.6+/-14.2lb]), and BMI (-1.6+/-3.3). These discrepancies also led to
substantial misclassification into weight categories, with reliance on
self-reported BMI underestimating the weight status of 20% of the sample.
CONCLUSIONS: Our findings suggest that similar to the general population,
wheelchair users are prone to errors when reporting their height and weight and
that these errors may exceed those noted in the general population.
