Diabetes Risk Can Be Detected With Help Of Metabolic Syndrome

A study in CMAJ establishes that metabolic syndrome can assist in detecting Aboriginal Canadians at risk of developing type 2 diabetes. This information can be particularly helpful in remote communities where two-hour oral glucose tolerance tests are not easily administered. http://www.cmaj.ca/press/pg617.pdf

Metabolic syndrome is the grouping of risk factors linked to diabetes and heart disease, such as obesity, high glucose, high cholesterol and hypertension. There is a three to five times higher probability for Aboriginal Canadians to develop type 2 diabetes compared to non-native Canadians.

In the Sandy Lake First Nation community in Ontario, 492 residents were involved in a ten year study. Findings showed that over this ten year period, the rate of incidence of diabetes was 17.5 percent. This rate increased in proportion with age, from 10.5 percent in the 10 to 19 age group to 43.3 percent in the 40 to 49 age group.

Dr. Anthony Hanley, University of Toronto and his team write: "The metabolic syndrome is not a diagnostic tool; however, the syndrome and its components may be used to communicate increased risk of developing diabetes within remote Aboriginal communities where the 2-hour oral glucose tolerance test to determine impaired glucose tolerance is not easily accessible." The researchers also pointed out that the use of intervention strategies could assist in the prevention or delay of diabetes in people who have the syndrome.
