The Burden of Diabetes
 16 million Americans
 22 million with impaired glucose tolerance




Leading cause of blindness
Leading cause of ESRD
Leading cause of limb amputations
2/3 die from coronary disease
 Per capita cost/pt 2x that of non-diabetic pt
 15% of all U.S. health costs; 25% of all Medicare costs
 40% of all costs are related to hospitalization

“But wait a bit,” the Oysters cried
“Before we have our chat.
For some of us are out of breath,
And all of us are fat.”

Globesity/Diabesity
• Obesity is more prevalent than malnutrition
in the world
• Obesity is a stronger predictor of morbidity
than poverty or smoking
• Framingham: obesity = smoking in terms of
life lost (~7yrs)
• Prevalence of obesity/overweight –
skyrocketing globally
Natural History: Pandemic
 DM in 1897 – 2.8/100,000 prevalence
 Since 1958 5-fold increase in prevalence of DM2
 From 1991-2001, 49% increase in overall
prevalence, 76% increase in age 30-39, 10-fold
increase in pediatric DM2
 From 1991-2001, 61% increase in obesity
 From 2003 to 2005 13% increase in diabetes
 1 in 3 children born in 2000 will develop diabetes

The Obesity Epidemic Has Reached America’s Pets.
August 16, 2004, AP Press Release
“The National Academy of
Science said that today that as
many as 40% of dogs and 12%
of cats presented at clinics are
either overweight or obese.”
“It seems as though
American’s bad lifestyle habits
have started to affect man’s
best friends.”

Childhood Obesity
• Rates continue to INCREASE, and overweight
and obesity appears to DISCRIMINATE by race,
sex, and geographic location
• Rates DOUBLED among children and TRIPLED
among youth since 1980
• The greatest INCREASES in rates are among:
– African-American girls
– Hispanic youth
– Those living in the south

Mississippi: 52nd out of 50 states
in the quality of diabetes care

No, really…

30-60% become diabetic
Weight loss and exercise prevent diabetes in
these pts
• Drug therapy for prevention is much less
effective
Diabetes is very preventable!
 With loss of 7% of body weight and 150
min/week of moderate exercise, diabetes
can be prevented about 58% of the time
 This was true for all subgroups – age, sex,
race, etc.
 Weight loss and exercise is twice as good at
preventing diabetes as medicine

Our fate, dear Brutus, is

ourselves…
Type 2 diabetes It’s not our genes, it’s
our blue jeans!
So What is Diabetes Care?
 Controlling complications
- blood sugar
- blood pressure
- lipids
 Losing weight!
 Becoming more active
 If you smoke, STOP!
Guidelines – the Short Form
1. BG, BP, Lipid control
2. Sceening: eyes, kidneys, feet
3. ASA use
4. Smoking cessation
Monitoring Goals in a Nutshell
•
•
•
•
•
•
•
A1c (<7=goal, >8=‘action required’)
BP control (<130/80)
Lipids (1: LDL<100, 2: HDL>40, 3: TG<200)
Retinal exams – yearly
Nephropathy screening (Microalbumin) - yearly
Foot screening – yearly and as indicated
ASA therapy – basically, if over 30 and not
contraindicated

Hypoglycemia
• The only diabetic emergency you may
routinely see on the farm
• Signs and symptoms: “he ain’t actin’ right”,
agitation, sweats, shakes, heart rate,
confusion
• Cause: blood sugar too low
• Cure: EAT SOMETHING RIGHT NOW!
Diabetes: What To Do?
 Prevention
- prevent obesity
- in those already overweight, prevent
diabetes
 Decrease the cost of existing disease
- decrease complications
- improve the quality of care
But How Do We Do It???
 System of care reforms – a new approach to this
disease is needed
 Education - for patients and providers
 Population strategies
- Children & Mothers
- Schools
- Regulatory efforts
 Research
- Basic
- Translational
The Big Picture
 The burden of both type 2 diabetes and obesity is rapidly
increasing, and shows no sign of stopping. If our society
does not change this, diabetes alone will bankrupt our
medical system.
 We can prevent most of the misery and cost, but we aren’t.
Diabetes is highly preventable; for those with diabetes, its
complications are highly preventable.
 Systematic approaches (e.g. – guidelines, disease
management, …) to diabetes FAR exceed the results of
traditional care and enhance provider effectiveness.

DHA/UMMC Delta Diabetes Project
Model
Multidisciplinary, chronic disease model; CBPR
Non-traditional features
Resource sparing
A service to primary care providers
Two arms: education and management – patient
self-management is the key
4500+ patients, 800+ visits/mo
Data and outcomes driven; novel applications of
teleinformatics
Excellent quality of care, outcome, and patient
satisfaction results
Successfully reproduced in community settings
DDP Outcomes
 Average patient has had diabetes for 10 years;
36% no-pay; 70% African-American
 Mean A1c on presentation = ~10.0%; mean
decrease in A1c –1.92%
 Improvement in blood pressure, lipids
 Outcomes are durable
 The model and its outcomes are easily
reproducible in community practice
 Outcomes independent of race and gender
 High quality of care measures: ~90+%
 High patient satisfaction measures: 97+%
 Resource utilization: 4 management and 2
education visits (year 1)
Delta Diabetes Project
 Regional system of diabetes care improvement for
Mississippi Delta
 Community-based participatory research
collaboration; sustainability
 6 sites
 Integral provider education
 Duplicating or exceeding UMMC results in all
outcomes
 Diabetes is only a test case chronic disease – CHF,
CV mortality, HTN, asthma, etc.
 Foothold for regional prevention programs in
diabetes, obesity, and CV mortality
