Can Using CGMS Improve Your A1C?

A study conducted by the JDRF and published in the prestigious New England Journal of Medicine this past October concluded that type 1 diabetic adults (defined as participants who were 25 years old or older) can improve their overall blood sugar control by using a continuous glucose monitoring system (CGMS). The study examined 322 adults and children with type 1 diabetes who were already receiving intensive therapy and randomly assigned them to CGMS use or a control group for half a year. Not surprisingly, 83% of the adult group reported using their monitor for at least six days per week, whereas only 30% of the 15-24 age group and 50% of those 8 to 14 years old did. After 26 weeks, glycated hemoglobin values were better in the CGMS group (compared to controls) for the adults and the youngest group of participants, but not for those who were 15 to 24 years old. As the study states, “Further work is need to identify barriers to effectiveness of continuous monitoring in children and adolescents.” We can all imagine what some of the barriers are in the teenagers, can’t we?
