Well, as everyone knows it's eating till you drop, eating fatty foods, the luau culture.  By that I mean eating, and over eating, is a big part of their culture.  It's sacred.
They, however, have just as much access to healthcare as the next guy does.  So, once again there is a call for "special" programs for Polynesian-Hawaiians only when it's a personal choice they make, and not the "lack" of health care.
