1253-P: Differences in Screening-Detected Type 2 Diabetes—Evidence from Two Campaign Setups in Denmark

Abstract

Background: Early detection of type 2 diabetes mellitus (T2DM) increases life expectancy of T2DM patients and reduces societal health care costs. Targeted screening campaigns are used for early detection of T2DM, but different campaign setups may yield different detection results. Methods: Between June and November 2022, the Danish Diabetes Association offered free capillary A1c tests to individuals at high risk of developing diabetes based on the Leicester’s Risk Score questionnaire (score ≥ 16 points). Two campaign setups were applied: a) an event-based community screening campaign in 20 of the largest Danish cities using a portable Point of Care Testing analyzer and b) a social media campaign offering at-home self-sampling tests using mailed Hemoglobin Capillary Collection System. Results: A total of 1,337 and 2,655 individuals at high risk were tested through the community and the social media setup, respectively. The proportion of men and women in both setups were evenly balanced across all age groups. However, compared to the social media setup, in the community setup the proportion of individuals aged below 60 years was 14 percentage points lower, while the proportion of individuals aged 70 years or older was 14 percentage point higher. While 2.6% of the participants in both setups had A1c values ≥ 48 mmol/mol, 8.8% in the community setup and 15.6% in the social media setup had A1c values of 42-47 mmol/mol. The relative difference in the proportion of participants with A1c values of 42-47 mmol/mol was balanced across all age groups. Conclusions: Targeted community and social media screening campaigns are complementary. While older individuals (70 years or above) tend to participate in the community screening campaign, younger individuals (below 60) tend to participate in social media screening campaign. However, social media campaigns for at-home self-sampling prove highly efficient in detecting individuals with A1c values of 42-47 mmol/mol compared to community campaigns.
