Abstract

AIM:

To determine the accuracy of self-reported anthropometric measurements in older Australian adults 60-70 years.

METHOD:

Self-reported anthropometric data from 103 community-dwelling participants (mean age 66 years) were compared with technician measurements. Difference and agreement were assessed using paired t-tests, correlation coefficients and Bland-Altman plots.

RESULTS:

Underreporting occurred for weight and hip circumference, especially among men, whereas waist circumference was slightly overreported, resulting in apparent underestimations of body mass index (by 0.42 kg/m(2) ) but overestimations of waist-to-hip ratio (WHR, by 0.02). Concordance correlation coefficients were generally high except for WHR. Self-reported circumference measures appeared to be more accurate than the derived WHR. The Bland-Altman plots revealed wide limits of agreement for all measures.

CONCLUSION:

Self-reported values correlated well with technician measured values and average discrepancies were small. However, use of self-reported anthropometric data may be used more appropriately for describing overall distribution in population studies than for monitoring changes at an individual level.
