Prevalence of diabetes mellitus in a rural area of Japan: By 75g OGTT.

Abstract
Tests for DM using the 75 g OGTT method (NDDG diagnostic criteria) were performed on 3145 persons living in rural areas of 8 different geographical regions of Japan (from Tohoku to Kyushu regions). Considerable regional difference was observed with western Japan tending to have higher DM and IGT rates than eastern Japan. The DM and IGT prevalence rates (for rural areas in Japan) were 3.9% and 6.9% respectively, and the DM detection rate was 2.8%. Comparison between normals and disturbance of glucose tolerance group (DM and IGT) on the basis of risk factors for atherosclerotic angiopathy showed that those with abnormal findings were definitely more numerous in the disturbance of glucose tolerance group.
