Abstract
To determine the prevalence of chronic diabetic complications in newly diagnosed diabetes mellitus (DM), microvascular and macrovascular complications were investigated in a populationbased Funagata Diabetes Study. The subjects were residents of Funagata, Yamagata Prefecture, who had been diagnosed with impaired glucose tolerance (IGT) and DM by the oral glucose tolerance test in the Funagata Diabetes Study (1990-92). During the same period, new outpatients in the diabetes clinic of Yamagata University Hospital were also investigated as a hospital-based diabetic control. The prevalence of retinopathy was 2.2% in patients with IGT, 7.1% in the DM subject and 41.2% in the hospital-based new outpatients. The prevalence of microalbuminuria and neuropathy showed almost the same tendency as that of retinopathy. The prevalence of macrovas cularcomplications such as an ischemic change in ECG (after Master-double loading) and the decrease in the ankle-pressure index was higher in DM than in IGT. Since even newly diagnosed DM have some chronic diabetic complications, glycemic control in the early stage is important to prevent chronic diabetic complications.
