摘要：Background: Diabetes represents one of the major health challenges in Switzerland, and early diagnosis and treatment is mandatory to prevent or delay diabetes-related morbidity and mortality. For the purpose of identifying affected individuals, early screening in pharmacies is a valuable option. In this survey, we aimed to determine blood glucose and metabolic control in an unselected population of individuals visiting Swiss pharmacies. Methods: The subjects responded to a short questionnaire and underwent a single capillary blood glucose test for screening purposes. They were classified as normal, indeterminate, impaired fasting glucose, and diabetes according to predefined blood glucose levels. Results: A total of 3135 individuals (mean age 56 years) in 18 cantons were screened in November 2010; of these, 4.2% (95% confidence interval [CI] 3.5–4.9) had previously been diagnosed with diabetes. Diabetes was newly diagnosed in 1.9% (95% CI 1.5–2.4), and 11.5% (95% CI 10.4–12.6) had impaired fasting glucose. Subjects with impaired glucose control had an increased body mass index, a frequent family history of diabetes, hypertension, hypercholesterolemia, smoking, and a low level of physical activity. Prevalence of impaired glucose control was different between the French/Italian-speaking part of Switzerland (new diabetes 4.9%; impaired fasting glucose 12.7%) and the German-speaking part (new diabetes 1.9%; impaired fasting glucose 10.3%). Conclusion: Our study shows a 6.1% prevalence of diabetes, of which about a third (1.9%) was previously undiagnosed, and 11.5% had impaired fasting glucose. Therefore, screening initiatives in pharmacies may be suitable for detecting people with undiagnosed diabetes.
