The Correlation Between Fear and Perceived Frequency of Hypoglycemia and Continuous Glucose Monitoring Metrics in Adults With Type 1 Diabetes Using Diabetes Technology: A 1-Year Analysis
Authors' conclusion
In adults using diabetes technology over 12 months, fear and perceived frequency of hypoglycemia showed no clear correlations with CGM metrics, suggesting both are influenced by more than glycemic profiles alone.
Study context
- Population
- Adults with T1D using rtCGM or hybrid closed-loop for 12 months; baseline mean age 41.0 ± 13.7 years, 55.9% women, diabetes duration 21.6 ± 12.7 years, HbA1c 7.6 ± 1.0%
- Participants
- 1,370 adults
- Comparison
- ALERTT1 vs INRANGE
- ALERTT1n = 254
- INRANGEn = 1,116
- Primary endpoint
- Correlations between hypoglycemia fear (HFS-worry, HFS-behavior), perceived hypoglycemia frequency (DTSQs-hypo) and CGM metrics
- Follow-up
- Baseline, 12 months and 12-month change
Methodological detailspooled analysis of ALERTT1 and INRANGE studies, 12-month follow-up
- Pooled analysis of ALERTT1 and INRANGE studies
- 12-month follow-up
Primary result
As reported in the abstract
Correlation of HFS-worry, HFS-behavior and DTSQs-hypo with CGM metrics
- HFS-worry, HFS-behavior and DTSQs-hypo showed no clear correlations with time in hypoglycemia or other continuous glucose monitoring (CGM) metrics at baseline, at 12 months, or over 12-month change
Further findings
Time <3.9 mmol/L · baseline to 12 months
- Decreased from 3.4 ± 3.5% to 2.3 ± 2.2% (mean ± SD)
Time <3.0 mmol/L · baseline to 12 months
- Decreased from 0.8 ± 1.4% to 0.5 ± 0.7% (mean ± SD)
HFS-worry · baseline to 12 months
- Decreased from 21.0 ± 12.9 to 16.8 ± 12.1 (mean ± SD)
DTSQs-hypo · baseline to 12 months
- Decreased from 3.3 ± 1.5 to 2.7 ± 1.4 (mean ± SD)
