Holtain-Kahn Abdominal Caliper

The Holtain-Kahn Abdominal Caliper Extra Long has been developed to aid the prediction of cardiac risk by measuring sagittal abdominal diameter in supine subjects.

This caliper makes a direct reading of the distance between the subject's back and the front of the subject's abdomen, and should be used on subjects with larger diameters.This caliper makes a direct reading of the distance between the subject's back and the front of the subject's abdomen.This sagittal abdominal diameter is highly correlated with the volume of visceral fat.

The inbuilt spirit level (which ensures a vertical measurement is taken) has helped to give estimates of intra observer precision which produced a mean of absolute deviation of 0.4cm, coefficient of variation of 2.5% and an intraclass correlation coefficient of 95.8 (Williamson D. et al. AMERICAN JOURNAL OF HUMAN BIOLOGY 1993; 5: 159-167).
