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).

Heya! I understand this is kind of off-topic but I had to ask.
Does running a well-establishe d website like yours require a massive amount work?

I'm completely new to writing a blog but I do write in my diary
everyday. I'd like to start a blog so I can easily share my personal experience and
feelings online. Please let me know if you have any suggestions or
tips for brand new aspiring blog owners. Appreciate it!

Matt - funny that you mention that, because we actually preparing a waist-to-height calculator. Coming soon :-)

What about stature? You’re telling me that as a 6ft 3 European with a waist (belly) of 39 inches I have the same risk as my Pilipino friend who has the same waist but is 5ft 4 in stature. Surely the waist to height ratio allows for this. J. Hodgdon, and M. Beckett, "Prediction of percent body fat for U.S. Navy men and women from body circumferences and height".

Well, there is no formal lower limits for waist circumference. It is more a consequence of GIGO (garbage in - garbage out) as 10 cm would never be a real measurement. To avoid that we could consider truncating the input at 30 cm.

10 cm waist circumference (4 inch) yields very low risk. This can't be right.
