Self-reported and measured BMI in Ireland: Should we adjust the obesity thresholds?
Madden, David - 2013
Using the nationally representative Slan dataset of 2007 we analyse the relationship between self-reported and measured BMI. We find that selfreported BMI significantly underestimates obesity rates and suggest that the traditional threshold of 30 should be adjusted downwards. We outline a number...
