Bimodality in the frequency distribution of plasma glucose 2 h after a 75-g oral glucose challenge has been demonstrated in only a few population groups, and the generalizability of the phenomenon remains unclear. Therefore, we have studied the distribution of 2-h glucose in 1813 Micronesians, aged 20 years and over, from an urbanized community of the Pacific Ocean Republic of Kiribati. The 2-h plasma glucose distributions were consistent with a mixture model comprising two lognormal components for age groups 30-39, 40-49 and 50+ years. The parameters of the mixture distribution were estimated by the method of maximum likelihood. The prevalence of non-insulin-dependent diabetes mellitus was ..
