T2DM Primary Prevention Case Detection and Diagnosis
Hello, I'm Norman Swan. Welcome to another programour serieson type 2 diabetes. Today we're talking aboutprimary prevention and early detection, and what to do when you find a problem. Type 2 diabetes affects over 7%of the Australian population aged 25 years or older. For every person diagnosed,there's one person who goes undetected, and that's a recipe for compliionsin almost every organthe body,
but you already know that. This program looks at newNHMRC evidencebased guidelines, and we'll be talking about preventionand early diagnosis, as I said. As usual, there are a numberof useful resources available on the Rural Health EduionFoundation's website: Now let's meet our panel. Ashim Sinha is the directorof Diabetes and Endocrinology at the Cairns Base and its Diabetes Centre,
and is also Associate Professorand Senior Research Fellow at James Cook University.Welcome, Ashim. Thank you, Norman. Mark Harris is a general practitioner and director of the Centrefor Primary Health Care and Equity at the University of NSW. Welcome, Mark. Good evening, Norman. Alan Barclay is a practising dieticianwith Diabetes Australia
and researcherat the University of Sydney. Welcome, Alan. Thank you. Welcome to you all. Mark, we are dealing with an epidemic. I know we've said it, but let's remindourselves of the statistics. The prevalence of diabetesis increasingAustralia, but worldwidewe're seeing a steady risethe number of peoplewith diabetes.
That's related not onlyto the ageing of the population but the shiftour lifestyles. That's happening indeveloped countries like Australia, but alsoless developedcountries, especiallythe Asian region. It's the most rapidly risingdiseasethe region. NORMAN: What about the prevalence of abnormal glucose tolerance?
MARK: That's certainly very high. We look at about 7.5% of peoplehaving diabetes, but there's another 10.5% of people who have impaired glucose tolerance, and about another 5% or 6% of people with impaired fasting glycemia. So we're looking at over 20%of the population over the age of 25 either with diabetesor who are at a high risk of diabetes.
