    To determine whether annual medical expenses for outpatients with type 2 diabetes mellitus requiring insulin therapy are high, we studied expenses for 58 patients—32 men and 26 women 43-90 years old—seen for disease management between January and December 2007. Annual medical expenses were 505,274.5±164,591.7 yen, with insulin cost accounting for 14.9%. A comparison of these expenses for 31 nonsenior patients <70 years old versus 27 senior patients ≥70 years old showed that insulin cost was significantly lower for senior patients, although overall annual medical expenses did not differ significantly between the two groups. The mean daily insulin dose was significantly lower in senior patients, but mean HbA1c did not differ significantly between the two groups. In short, annual medical expenses do not necessarily rise with age.

    Purpose: We studied borderline-diabetes risk factors.
    Subjects and Methods: Subjects were men undergoing a 75 g oral glucose tolerance test (75 g OGTT) twice or more at 3-year or longer intervals over the last 10 years. Test results were evaluated based on Japanese Society of Diabetes Mellitus criteria. Patients with borderline or diabetic conditions were excluded. Patients maintaining normal glucose tolerance (NGT) were assigned to the NGT group. Those showing change from normal to borderline glucose tolerance were divided into 4 groups based on plasma glucose tolerance test results-IFG, 60 IGT, IGT, and IFG+IGT. We studied risk factors in each group borderline.
    Results: Borderline risk factors included reduced insulin sensitivity and an increased plasma glucose level 60 minutes after 75 g OGTT at the start of observation, both of which were common to all groups.
    Conclusions: Patients showing a plasma glucose increase 60 minutes after loading should be considered at risk for deterioration to borderline levels.
