Move over BMI. Make room for NC.

July 12th, 2010 | Philip Mann

The Body Mass Index (BMI) has long been the standard for assessing obesity as its simple, convenient and cheap.  But it has also been dogged by complaints that it’s inaccurate and limited.  A study in the journal Pediatrics suggests there might a more accurate measurement to assess obesity in children – neck circumference (NC).

Neck circumference could give a more accurate measurement of someone’s body fat composition than BMI, particularly in the all important spare tire area.  NC has a strong correlation with central adiposity (fat around the middle), which studies have shown is a good indicator of obesity-related complications.

In the battle against obesity, more accurately measuring body fat composition is a big step in the right direction.  But obesity management, and the management of metabolic diseases commonly associated with obesity such as type 2 diabetes, high cholesterol and hypertension are things we need to focus on now. 

Through the use of behavioral science, we’ve learned that while the conditions varied, the motivations and barriers to change of patients diagnosed with those conditions are very similar.  We’ve called this a “metabolic mindset”, and believe that if approached correctly, is susceptible to change.

  1. Thanks for the post. I posted this on digg =)

  2. Greetings I just now finished reading through your site and I’m very impressed. I do have a couple of questions for you however. Are you thinking about doing a follow-up article about this? Do you think you’re going to keep updating as well? Additionally if you get an opportunity could you rate my acai berry web page if you have the opportunity?
