While the ethnic make up of the New Zealand population is predominantly Eur
opean, the Polynesian population, consisting of indigenous New Zealand Maor
i and more recent immigrants from the other Pacific Islands is increasing r
apidly. The prevalence of diabetes in these Polynesians is high. There is a
lso an increasing prevalence of obesity, and obesity is a greater problem a
mongst Polynesian people. The number of elderly people in the population is
increasing. All of these demographic changes are increasing the incidence
and prevalence of Type 2 diabetes. The incidence of Type I diabetes is also
rising, although the reasons for this are unknown. Diabetic nephropathy is
the most common cause of end stage renal failure in New Zealand. Polynesia
n people with diabetes, and in particular Maori, have a very high rate of d
iabetic nephropathy and develop renal failure at a more rapid rate than Eur
opean patients with nephropathy relating to Type I diabetes. The propensity
for Maori patients with Type 2 diabetes to develop renal failure may relat
e to a younger age at the onset of diabetes, a genetic susceptibility to ne
phropathy, and socio-economic or cultural factors leading to less adequate
medical care. (C) 2000 Elsevier Science Ireland Ltd. All rights reserved.
