"Welcome, introductions and objectives"Dr. Lawrence A. Leiter (biography)
English - 2002-04-26 - 17 minutes
|
 | (21 slides) |
Summary :
In this introductory talk at the beginning of the first Working Group on Insulin Resistance conference, Dr Leiter gives an overview of some epidemiological aspects of type 2 daibetes, its etiology, complications and pathology. Studies such as UKPDS and ADOPT are discussed, as well as CDA guidelines for glycemic control. Finally, Dr Leiter outlines the objectives of the Working Group on Insulin Resistance, which are: to initiate a Canadian working group of leading clinicians and scientists to address issues related to insulin resistance and type 2 diabetes; to examine, discuss and debate current and emerging scientific evidence on insulin resistance and type 2 diabetes; and to discuss clinical issues and approaches leading to improved management of type 2 diabetes and prevention of disease progression.
Learning objectives :
The participant will get an overview of some current topics in the nature and treatment of type 2 diabetes.

OBJECTIVE--To assess the prevalence of undiagnosed diabetes and glucose intolerance in individuals > or =40 years of age who contacted their family physician for routine care. RESEARCH DESIGN AND METHODS--The study used a stratified randomized selection of family physicians across Canada that was proportional to provincial and urban/rural populations based on Statistics Canada Census data (1996). Consecutive patients > or=40 years of age were screened for diabetes. If a casual fingerprick blood glucose was >5.5 mmol/l, the patient returned for a fasting venous blood glucose test. If the fasting blood glucose was 6.1-6.9 mmol/l, a 2-h 75-g post-glucose load venous blood glucose was obtained. Results of these tests were used to classify patients in diagnostic categories. RESULTS--Data were available for 9,042 patients. Previously undiagnosed diabetes was discovered in 2.2% of the patients, and new glucose intolerance was found in an additional 3.5% of patients. Overall, 16.4% of patients had previously known diabetes. The decrease in fasting plasma glucose criterion from 7.8 to 7.0 mmol/l resulted in a 2.2% versus a 1.6% prevalence of new diabetes. Several risk factors were reported in a significantly greater proportion of patients with new glucose intolerance and either new and known diabetes compared with the normal glucose tolerance group of patients. CONCLUSIONS--Routine screening for diabetes by family physicians is justified in patients >or =40 years of age, given the finding of previously undiagnosed diabetes in 2.2% of these patients and newly diagnosed glucose intolerance in an additional 3.5% of these patients. Another 16.4% of primary care patients > or =40 years of age have known diabetes. This has important implications regarding health resources and physician education.
