<qa>  What is the name of the population that is matched with non-Maori?It has been proposed that a higher cut off for BMI body mass index is to be used in Maori to define overweight and obesity. However, no one has assessed the prevalence of co-morbid conditions associated with BMI. It is well known that Maori are at greater risk of diabetes and cardiovascular disease compared to non-Maori and a delay in the identification of those who are overweight and obese may be detrimental for Maori. We will assess BMI, other measures of adiposity and prevalence of co-morbid conditions with a comparison with a similar matched non-Maori population.
