Aims To determine the prevalence of unidentified diabetes mellitus among 67‐year‐olds in Denmark participating in a screening programme focusing on cardiovascular disease and diabetes, and to describe glycaemic levels in individuals according to point‐of‐care HbA 1c combined with self‐reported diabetes status. Methods In this cross‐sectional, retrospective, population‐based study, all people aged 67 years living in the Viborg municipality were invited to take part in the Viborg Inter‐sectorial Screening Programme ( VISP ), which focuses on cardiovascular disease and diabetes. The VISP study was initiated in August 2014 and is ongoing. During the first 2 years of the programme, we stratified participants into groups based on their self‐reported diabetes status and a single HbA 1c measurement. Results A total of 1802 individuals were invited to participate, and 1501 consented, seven of whom were excluded because of missing data (HbA 1c or diabetes status), resulting in an 82.9% participation rate ( n =1494). Among those reporting not to have diabetes, 3.3% ( n =45) had an HbA 1c level ≥48 mmol/mol (6.5%). In the same group, 16.7% ( n =226) had an HbA 1c level of 41–48 mmol/mol (5.9–6.5%). Among those self‐reporting the presence of diabetes, 30.1% ( n =43) had an HbA 1c level ≥58 mmol/mol (7.5%). Conclusions The prevalence of unidentified diabetes was 3.3% based on a single HbA 1c measurement. Furthermore, 16.7% of those reporting not to have diabetes had an HbA 1c level of 41–48 mmol/mol (5.9–6.5%), representing a subgroup with an increased risk of developing diabetes. Among those with self‐reported diabetes, 30.1% had an HbA 1c level ≥58 mmol/mol (7.5%) and 6.3% had a level >74 mmol/mol (8.9%).
