Nothing at all, some people have made a career out of it
I can see nothing at all in their
published stuff relating to identification of at risk individuals, other than clinical judgement, (whatever that is!), BMI, and waist measurement, so I guess you could assume that they havn't caught on. (Sorry to be coy, but they would have considered other measures too.)
I'm making a few assumptions here, but I guess what NICE are trying to do, are marry up the available interventions, (and I have to say, the evidence for some of these is questionable), with a more accurate method of identifying at risk individuals.
Primary care foot soldiers are in an ideal position to deliver this, as we, generally, are very accessible to our population, and are have the experience of delivering systematic care through a patients lifetime.
On a practical note, measuring hips and wrists probably won't happen, unless we could demonstrate real health benefit. It's an uphill struggle gaining the waist measurements- I'm sure you know the pressures.
