Abstract

This study aimed to investigate the prevalence of glucosuria and the characteristics of diabetes in schoolchildren as detected by a school urine glucose screening program implemented from 2010 to 2013 in the Jeonbuk province area of Korea. A total of 110 children without known diabetes were analyzed. They were checked with an oral glucose tolerance test (OGTT) with other laboratory tests and their clinical data were collected. A total of 707,238 schoolchildren from a school population of 1,064,999 were screened for glucosuria. In total, over a 4-year period, 545 schoolchildren (0.077%) were positive for glucosuria on the second urine test. The prevalence of glucosuria was more common among middle and high schoolchildren than among elementary schoolchildren. Among 110 students who completed the OGTT to confirm diabetes, 40 were diagnosed with diabetes mellitus (DM); 39 children, type 2 diabetes mellitus (T2DM) and 1 child, slowly progressive insulin dependent diabetes mellitus (SPIDDM). The mean annual incidence of diabetes was 5.6 per 100,000 schoolchildren and adolescents. The subjects with diabetes diagnosed through the urine screening test showed minimal or no symptoms of diabetes. The students with diabetes were more likely to be woman and obese, and they have a higher body mass index, higher cholesterol, triglyceride, insulin, C-peptide, and fasting glucosuria values than the students with normal glucose tolerance. We identified 40 new cases of diabetes in the Korean schoolchildren with asymptomatic glucosuria on urine glucose screening. This finding shows that school urine glucose screening is a feasible and simple method for early detection of asymptomatic T2DM.
