Abstract

To explore time trends in diabetes management and intermediate health outcomes of people with type 2 diabetes, data from two population-based survey studies were compared. The surveys were conducted in the Augsburg region of Southern Germany in 1997/98 and in 2004/05, and included physical examinations, interviews, self-administered questionnaires and laboratory tests. Data from 334 participants aged 40-84 were analysed, including a longitudinal sub-sample of 50 persons. Results show significant time trends towards improvements over the seven year period. Controlling for age, sex, education and duration of diabetes, people felt better informed about diabetes (Odds Ratio (OR) 1.87; 95% CI: 1.12, 3.14) and stated greater adherence to the treatment plan (OR 4.42; CI: 2.62, 7.45) as well as higher participation in diabetes education programmes (OR 2.20; CI: 1.44, 3.38). Mean haemoglobin A1c levels decreased by -0.97% from 7.3% to 6.3% (CI:-0.66%, -1.28%). Physical activity (> or =1 h/week) was more frequent (OR 2.75; CI: 1.65, 4.59), although Body Mass Index increased by 1.43 kg/m (2) (CI: 0.86, 2.00). The positive changes in disease management and metabolic outcomes for type 2 diabetic patients between 1997/98 and 2004/05 indicate...Continue Reading

Biomarkers for Type 2 Diabetes

Biomarkers can help understand chronic diseases and assist in risk prediction for prevention and early detection of diseases. Here is the latest research on biomarkers in type 2 diabetes, a disease in which the body is unable to produce or properly use insulin.
