Rural-urban and ethnic comparisons of impaired glucose tolerance and diabetes mellitus were made in the biracial population of Fiji in 1980. No statistically significant differences existed in age-standardized impaired glucose tolerance prevalence between rural and urban groups or between Melanesians and Indians. The age-standardized prevalence of diabetes(More)
A population survey in 1982 has confirmed that Nauruan adults suffer from an extremely high prevalence of Type 2 (noninsulin-dependent) diabetes mellitus. The crude population prevalence of Type 2 diabetes was 24%. Abnormal glucose tolerance (impaired glucose tolerance and diabetes) was present in over 40% of the adult population and exceeded 80% in both(More)
A population-based survey of 2938 subjects has demonstrated a high prevalence of non-insulin-dependent diabetes (NIDDM) in the Micronesian population of Kiribati (formerly the Gilbert Islands). This finding provides further support for evidence from Nauru, Guam, and the Marshall Islands that Micronesians are particularly susceptible to NIDDM. The(More)
Glucose tolerance and the prevalence of impaired glucose tolerance (IGT) and diabetes in the Polynesian populations of Rarotonga and Niue were studied in 1980. Both Rarotongans and Niueans have been considerably influenced by sociocultural modernization and (in the case of Rarotonga) tourism. In both populations, the prevalence of abnormal glucose tolerance(More)
In Fiji Melanesian and Indian men, prevalence of diabetes is more than twice as high in those graded as sedentary or undertaking light activity as in those classed as performing moderate or heavy exercise. This difference was present in both ethnic groups, and maintained when age, obesity, and urban/rural- status were taken into account. It is concluded(More)
The association between the prevalence of diabetes and three suspected risk factors--overweight, physical inactivity, and urbanization--has been studied in 5519 subjects from three Pacific populations: Melanesians and migrant Asian Indians in Fiji in 1980, and Micronesians in the Republic of Kiribati (formerly the Gilbert Islands) in 1981. Associations were(More)
A longitudinal study of 266 adult residents of the Pacific Island of Nauru (1975-1976 and 1982) has shown an annual incidence of noninsulin-dependent diabetes of 1.6 per cent per annum. Factors associated with the subsequent development of glucose intolerance were determined by means of regression techniques. The two-hour, post-load plasma glucose(More)
An epidemiologic survey of the whole adult Micronesian population of Nauru in the Central Pacific conducted in 1982 has confirmed that Nauruans, along with Pima Indians, suffer the highest rate of abnormal glucose tolerance yet recorded. To establish the morbid effects of hyperglycemia in this population, all responders to the diabetes survey were(More)
The frequency distribution of log plasma glucose concentrations in certain populations show two distinct subgroups--a non-diabetic group and a hyperglycaemic group--when suitable methods of distributional analysis are used. These two groups show up as a double peak (bimodality) in the best-fit frequency distributions of log plasma glucose, and the(More)
Most epidemiological studies of diabetic retinopathy have been based on clinic populations. This produces a bias for the more severe cases and later stages of the disease. To avoid this bias, 1567 Micronesian adults of Nauru (82% of total adult population) were examined. Diabetic retinopathy was classified by both the World Health Organization (WHO)(More)
