Waist circumference

Instructions:
1. Measure your waist circumference at a horisontal line one inch above your belly button.

Background:

Waist circumference is a reliable indicator of obesity and increased risk of lifestyle diseases. Waist-to-hip ratio is also being used for the same purpose, but research has shown that using only the waist measurement gives you the same level of information.

The calculator uses the reference values given in the bottom reference (Bray).
