Interesting that the Maori and Pacific rates are pretty much the inverse of the smoking graph in the post below.
Calling Pacific people 'obese' is problematic in my view. If I go into the local supermarket just before school I see lots of Pacific girls and lots of Asian girls. The Pacific girls are often very tall - tower over me - they appear what I would call big-boned, and they ooze health and vitality. The Asian girls are generally more petite, and slighter in build, but also look comfortable and happy in the bodies they have.
Do you think if we swapped a couple around at birth and had the Pacific girl raised in the Asian family and vice versa they would look very different by age 16?
