Objectives: 1. To highlight the World Diabetes Day, 14 November 2011 2. Scientific perspective of the day.
The Impact of Diabetes: Million lives are lost annually Millions of $ lost income and Productivity. 1 million amputation per year. Diabetes kills 1 person in every 8 seconds. Every 10 seconds, 2 people develop diabetes. -IDF Bulletin; November 2011.

How is the day marked? Millions of people in over 160 countries. Walks and cycle rides Lighting buildings and monuments in blue. Radio & Television Program. Sports events. Free screenings for diabetes. Public information meetings.
How is the day marked? (Continued) Poster & leaflet campaigns. Diabetes workshop & exhibitions. Press conference. News paper & magazine articles. Events for children & adolescents. Activities & lessons in schools.
1991 World Diabetes Day begins The International Diabetes Federation and the World Health Organization created World Diabetes Day in response to diabetes epidemic 15
Every year on November 14, World Diabetes Day brings diabetes to the attention of the world.
November 14 is the birthday of Frederick Banting, one of the discoverers of insulin. (c) Banting House National Historic Site of Canada
The theme is set by the International Diabetes Federation and the World Health Organization.
In 2006, the United Nations passed resolution 61/225. It asks the world to observe November 14 as World Diabetes Day and to take action to address the diabetes threat.
. . . to become a truly global event.
The campaign evolved from one day in the year to a multi-year campaign 2002: Your Eyes and Diabetes 1991: Diabetes Goes Public 1992: Diabetes: A Problem of All Ages 2003: Diabetes and Kidneys in All Countries 2004: Diabetes and Obesity 1993: Growing Up with Diabetes 2005: Diabetes and Foot Care 1994: Diabetes and Growing Older 2006: Diabetes and the 1995: The Price of Ignorance Disadvantaged and Vulnerable 1996: Insulin for Life! 2007 -2008: Diabetes in Children and Adolescents 1997: Global Awareness: Our Key to a Better Life 2009 -2013: Diabetes Prevention and Education 1998: Diabetes and Human Rights 1999: The Costs of Diabetes 2000: Diabetes and Lifestyle in the New Millennium 2001: Diabetes and Cardiovascular Disease
2009 -2013 Diabetes Education and Prevention The campaign slogan is: Let's Take Control of Diabetes. Now.
2009 -2013 Understand diabetes and take control
The global symbol for diabetes was developed during the Unite for Diabetes campaign. Why a circle? A positive symbol across cultures, the circle symbolizes life and health. Why blue? The colour blue reflects the sky that unites all nations. The blue border of the circle reflects the colour of the sky and the flag of the United Nations. The blue circle signifies the unity of the global diabetes community in response to the diabetes epidemic. http: //www. diabetesbluecircle. org

The Science: Type 2 Diabetes Prevention
The Diabetes prevention program (DPP) One of the largest 27 -Centre trial. Started on 1996. Total participants : 3, 234. Three arms trial : Lifestyle intervention group. Metformin group Control group
Diabetes Prevention Program Clinics . . 27 clinics 3, 819 participants
DPP Goals Primary To prevent or delay type 2 diabetes in people with impaired glucose tolerance (IGT) Secondary Reduce heart disease and stroke Reduce risk factors for heart disease and stroke
Study Interventions Screen Randomize Standard lifestyle teaching Intensive Lifestyle (n = 1079) Metformin (n = 1073) Placebo (n = 1082) Troglitazone n= 585 Until 6/98
LIFE STYLE BALANCE INTERVENTION WEIGHT LOSS GOAL. PHYSICAL ACTIVITY GOAL. DIETARY MODIFICATION.
Life style Intervention (Ctd) 7% loss of initial weight. In the first six month. Maximum wt. loss ; first 20 -24 weeks. 1 -2 lbs/week. Maintenance of wt. loss.
150 mins / week moderate exercise. Intensity to brisk walking. Minimum 3 times/week. Minimum 10 mins per session. Maximum 75 mins per session Evidence based, effective, feasible. Suitable for long term maintenance.
Double blind placebo control trial of Metformin. Both groups advised for lifestyle modification. Dose of Metformin : 850 mg/day orally – 1 st month. 850 mg twice daily subsequently. Average follow op period : 2. 8 years
Average Weight Change + Placebo Metformin Lifestyle 0 6 12 18 24 30 Months in study 36 42
Percent of all participants developing diabetes Cumulative incidence (%) Lifestyle (n=1079, p<0. 001 vs. Met , p<0. 001 vs. Plac ) 40 Metformin (n=1073, p<0. 001 vs. Plac) Placebo (n=1082) 30 Metformin 20 Lifestyle 10 0 0 1 2 Years in study 3 4

Weight loss improves glycaemic control in type 2 diabetes FPG, fasting plasma glucose Anderson et al. J Am Coll Nutr 2003; 22: 331– 9
Weight loss increases lifespan In type 2 diabetes: • Each 1 kg of weight loss in the first year was associated with increased survival by 3– 4 months • 10 kg of weight loss predicted restoration of about 35% in life expectancy Lean et al. Diabetes Metab 1990; 7: 228– 33

Prevention of DM Objective: l Is DM is preventable? l Types of prevention: – Primary –Secondary –Tertiary • Screening of high risk individuals • Life style modification
Prevention of DM Types of prevention: 1. Primary prevention: Measures to avoid the onset of the disease. 2. Secondary prevention: Early detection Prompt treatment. 3. Tertiary prevention: To prevent and or delay further progression of complications.

Obesity
Diabetes incidence rates by BMI
The campaign has grown in strength from humble beginnings. . .
Poly Count grams of Saturated fat. <10 if you have heart disease; <20 g for others Sat Check food labels for hydrogenated oils and keep to a minimum. Avoid Fast Foods Trans Make this the main fat in you diet. Use olive oil, canola & peanut oil for cooking. Mono Omega 3: Fatty fish 2 times a week Omega 6: controversial, watch the science develop, minimal amount
