ABSTRACT
This study aimed to assess the diagnosis of diabetes after detecting high blood glucose levels through screening among insured individuals in Gunma, Japan. Data for men and women 35 to 74 years of age were provided by Japan Health Insurance Association, and 4133 individuals with high blood glucose levels while not currently being treated for diabetes were included in the study. About 13% received a diagnosis of diabetes at a subsequent physician visit, and individuals who were under treatment for hypertension were less likely to receive the added diagnosis of diabetes compared with those not being treated for hypertension (odds ratio = 0.42 from a logistic regression model). Fasting blood glucose levels were significantly improved in the next year only among individuals with a confirmed diagnosis of diabetes.
