Differences in screen-detected type 2 diabetes in two targeted community-based screening campaigns in Denmark
Authors' conclusion
Mobile units and at-home self-sampling are complementary screening approaches, finding similar rates of screen detection with HbA1c ≥48 mmol/mol (≥6.5%), though the latter is more efficient in detecting individuals with HbA1c values of 42-47 mmol/mol (6.0-6.4%).
Study context
- Population
- Individuals at high risk of diabetes by Leicester's Risk Assessment score, offered free capillary HbA1c tests by the Danish Diabetes Association, June 2022–November 2024

- Exposure
- At-home self-sampling vs mobile unit screening
- At-homen = 5,609
- Mobile unitn = 4,051reference
- Outcome
- Detection rates of prediabetes and diabetes
