Social disadvantage and technology use among adults with type 1 diabetes in Quebec: A cross‐sectional study using data from the Canadian T1D ( BETTER ) Registry
Authors' conclusion
Social disadvantage is associated with lower uptake of insulin pumps and CGM among Quebec adults with T1D, though public funding partially mitigates disparities in CGM use. Given the benefits and increasing recommendations for automated insulin delivery, strategies to increase the uptake of diabetes technologies among socially disadvantaged individuals are required.
Study context
- Population
- Adults with T1D in Quebec, Canada (BETTER Registry), where public funding is available for continuous glucose monitor (CGM) but not for insulin pumps; survey data April 2019 to October 2023
- Participants
- 2,380 adults
- Exposure
- Social disadvantage indicators vs absence of the indicator
- Outcome
- Insulin pump and CGM use
Methodological detailsregistry-based, self-reported survey data
- Registry-based
- Self-reported survey data
Main finding
As reported in the abstract
- Insulin pump use (whole cohort)
- 37.4%
- CGM use (whole cohort)
- 82.5%
- Insulin pump use, income <$80 000: OR
- 0.64 (0.50-0.82) (95% CI)
- Insulin pump use, no post-secondary education: OR
- 0.62 (0.46-0.85)
- Insulin pump use, non-White Race: OR
- 0.47 (0.30-0.73)
- Insulin pump use, public insurance: OR
- 0.47 (0.35-0.62)
- CGM use, income <$80 000: OR
- 0.61 (0.45-0.83)
- CGM use, public insurance: OR
- 0.61 (0.45-0.83)
Observational data: associations, not effects.
Further findings
Clinical outcomes by technology use
- Insulin pump and CGM use both associated with lower HbA1c but not severe hypoglycaemia or diabetes hospitalisation
