Reliability of body fat distribution measurements. The ARIC Study baseline cohort results. Atherosclerosis Risk in Communities Study.

Abstract

These results confirm previous findings which indicate that the reliability of girth measurements is greater than for skinfold measurements. As a consequence, the waist to hip ratio is less affected by measurement error than the skinfold ratio. Moreover, the expected gain in reliability from using the average of two skinfold measures, taken in succession, was not realized, indicating that when measurements are taken in rapid succession by the same technician, statistical independence between measures is questionable.
