Body Shape Index (BSI)

Also called A Body Shape Index (ABSI)

Body Shape Index (BSI) is a metric for assessing the health implications of a given human body height, mass and waist circumference. The inclusion of the latter is believed to make the BSI a better indicator of the health risks from excess weight than the standard Body Mass Index. ABSI value analysis comes from Nir Y. Krakauer and Jesse C. Krakauer, doi:10.1371/journal.pone.0039504 published in 2012. ABSI is Waist circumference divided by multiplication of BMI power to 2/3 and square root of Height.

Measurement

Waist circumference: The waist circumference should be measured at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest, using a stretch‐resistant tape that provides a constant 100 g tension.

Height (stature): Standing height is the measurement the maximum distance from the floor to the highest point on the head, when the subject is facing directly ahead. Shoes should be off, feet together, and arms by the sides. Heels, buttocks and upper back should also be in contact with the wall when the measurement is made. Height measurement can vary throughout the day, usually being higher in the morning, so to ensure reliability height should be measured at the same time of day.

Body weight (mass): To improve reliability, weigh routinely in the morning (12 hours since eating). Body weight can be affected by fluid in the bladder (weigh after voiding the bladder).

In each procedure the person stands with minimal movement with hands by their side. Shoes and excess clothing should be removed.

If there is something wrong, you should consults your health problems with your physician. This index is only indicator of potential healthy risks and it is not absolutely reliable.
