Evaluation of Effects of Continuous Glucose Monitoring on Physical Activity Habits and Blood Lipid Levels in Persons With Type 1 Diabetes Managed With Multiple Daily Insulin Injections: An Analysis Based on the GOLD Randomized Trial (GOLD 8)

J Diabetes Sci TechnolPublished Secondary analysis of the GOLD randomised trial

Authors' conclusion

Although many patients experience it easier to perform physical activity when monitoring glucose levels with CGM, it does not influence the amount of physical activity in persons with type 1 diabetes. Blood lipids, apolipoprotein, and hsCRP levels were similar during CGM and SMBG.

Study context

Population
Patients with T1D managed with MDI
Comparison
Continuous glucose monitoring (CGM) vs self-monitoring of blood glucose (SMBG)
Methodological detailscross-over, 4-month wash-out between the two 6-month treatment periods; 16-month trial
  • Cross-over
  • 4-month wash-out between the two 6-month treatment periods; 16-month trial

Primary result

As reported in the abstract

Physical activity (International Physical Activity Questionnaire (IPAQ) score)
  • No changes in physical activity during CGM or SMBG
  • CGM vs SMBG: P = 0.16

Further findings

OutcomeDifference (mmol/mol)P value
HbA1c4.2P < 0.001
  • HbA1c: NGSP 0.39%; 136 participants with no change in lipid-lowering medication

Blood lipids, apolipoproteins and high-sensitivity C-reactive protein (hsCRP)

No significant changes in LDL, HDL, triglycerides, total cholesterol, apolipoprotein A1, apolipoprotein B1 or hsCRP during CGM and SMBG
