Rural-urban comparisons of diabetes prevalence were made in te Polynesian
population of Western Samoa. The prevalence of diabetes in the urban
population was almost three times that in the rural (10.1% versus 3.6%).
While the urban male and female subjects were significantly more obese than
their rural counterparts, the difference in prevalence rate could not be
wholly explained on the basis. Diabetes prevalence was still approximately
double in urban subjects when we compared the rural and urban populations
after removing the differences in obesity and age. The results suggest
that, apart from age and obesity, other factors, e.g., differences in diet,
physical activity, or stress (or a combination of these), may participate
in the rural to urban difference in diabetes prevalence.
