Continuous glucose monitoring can be associated with improved glycemic control in adults with type 1 diabetes. Further work is needed to identify barriers to effectiveness of continuous monitoring in children and adolescents. (ClinicalTrials.gov number, NCT00406133.)

It is possible to identify individuals at high risk for type 1 diabetes and to enroll them in a large, multisite, randomized, controlled clinical trial. However, oral insulin did not delay or prevent type 1 diabetes. Further studies are needed to explore the potential role of oral insulin in delaying diabetes in relatives similar to those in the subgroup with higher IAA levels.

OBJECTIVETo evaluate factors associated with successful use of continuous glucose monitoring (CGM) among participants with intensively treated type 1 diabetes in the Juvenile Diabetes Research Foundation Continuous Glucose Monitoring Randomized Clinical Trial.RESEARCH DESIGN AND METHODSThe 232 participants randomly assigned to the CGM group (165 with baseline A1C ≥7.0% and 67 with A1C <7.0%) were asked to use CGM on a daily basis. The associations of baseline factors and early CGM use with CGM use ≥6 days/week in the 6th month and with change in A1C from baseline to 6 months were evaluated in regression models.RESULTSThe only baseline factors found to be associated with greater CGM use in month 6 were age ≥25 years (P < 0.001) and more frequent self-reported prestudy blood glucose meter measurements per day (P < 0.001). CGM use and the percentage of CGM glucose values between 71 and 180 mg/dl during the 1st month were predictive of CGM use in month 6 (P < 0.001 and P = 0.002, respectively). More frequent CGM use was associated with a greater reduction in A1C from baseline to 6 months (P < 0.001), a finding present in all age-groups.CONCLUSIONSAfter 6 months, near-daily CGM use is more frequent in intensively treated adults with type 1 diabetes than in children and adolescents, although in all age-groups near-daily CGM use is associated with a similar reduction in A1C. Frequency of blood glucose meter monitoring and initial CGM use may help predict the likelihood of long-term CGM benefit in intensively treated patients with type 1 diabetes of all ages.

These findings indicate that overnight hypoglycemia after exercise is common in children with T1DM and support the importance of modifying diabetes management after afternoon exercise to reduce the risk of hypoglycemia.

The hospitalization of a child at the onset of insulin-dependent diabetes mellitus (IDDM) has become routine in many parts of the world, although controversy exists about its necessity. We examined the patterns of medical care use and the prognosis for acute complications after diagnosis for children with newly diagnosed IDDM in Colorado from 1978 to 1982. We reasoned that if children cared for entirely in outpatient settings at diagnosis had no more frequent acute complications after diagnosis than hospitalized children, we would be encouraged to further explore other potential benefits of outpatient care at onset. Twelve percent of 305 children studied statewide received only outpatient care during the first 2 wk after diagnosis, and, prognostically, their subsequent hospitalization and ketoacidosis rates were 2-3.7 times lower than those of children who received any inpatient care. No differences were noted for severe insulin reaction rates. Children classified as "severe" at onset, or with parents of lower education and income, or aged 10-14 yr at onset, regardless of care setting, had 2-4 times higher subsequent acute complication rates after onset than children without these characteristics. These findings, together with data on nights hospitalized and average length of stay in hospital at onset, suggest that a 42% reduction in total nights hospitalized could occur if children with "mild" or "normal" severity at onset were treated largely in the outpatient setting.
