THE PROBLEM
The Problem of Diabetes is Growing….
Pre-diabetes: • 86 million Americans
• 35% of all adults• 50% of adults >65
• Progression to diabetes 5 – 15% per year
Diabetes in U.S. – Tip of the Iceberg
Diabetes – • 29 million Americans• 8.3% U.S. population
Why is this happening?

Etiology of Obesity: Dietary IntakeDaily caloric intake increased dramatically in the past 30 years
- Increased portion sizesMarketplace portions are 2-
8 fold larger than FDA recommendations
- Increased frequency of eating out/fast food consumption
- Fast-food consumption has strong positive associations with weight gain and insulin resistance

WHAT CAN WE DO ABOUT IT?
The Diabetes Prevention Program
Diabetes Prevention – the DPP
3-arm nation-wide RCT with >3,000 participants with pre-diabetes (IGT) Intensive Lifestyle Intervention Metformin (Diabetes medication) Placebo (Basic advice)
Development of Diabetes
Placebo Metformin Life-style
Development of diabetes 11.0% 7.8% 4.8% (percent per year)
Reduction of diabetes ---- 31% 58% compared with placebo
Number needed to treat ---- 13.9 6.9
to prevent 1 case in 3 yrs
All ethnic/racial groups Men and women, lean, plump or fat All adults, especially those over age 60

SO WHY DON’T HE HAVE A DIABETES PREVENTION PROGRAM ON EVERY STREET CORNER?

Health PayersEmployersIndividuals
Minimize Costs : Optimize Effectiveness
Barriers to “DPP for All” Evidence only supports Pre-Diabetes
Requires a blood test Not a routine in primary care settings Not well understood by public
Need for Scalable Models Purchaser must believe a program has fidelity Programs must be widely available (meet demand) Must be cost effective
What do we translate?
Goals for DPP Translation Maintain fidelity to “core” evidence
Paying for intensive lifestyle interventions is a value for the dollar in adults with PRE-DIABETES
We don’t know if other strategies are cost effective Less intensive interventions Targeting lower risk groups (e.g. all obesity)
Adopt “practical” solutions for barriers Seek to demonstrate possible cost savings
Minimize intervention costs Preserve effectiveness (weight maintenance)
Developing a Scalable Model
Simplify testing Lower intervention costs Partner with community to share

A FEW EXAMPLES FROM OUR CENTER…
P L
Diabetes Education & Prevention with a Lifestyle Intervention Offered at the
YMCA
D E O Y
Why the Y? Lower Cost Programs
Lower cost “lay” group leaders Operate to achieve cost recovery only Policy to turn no person away for inability to
pay
Past experience with national program scaling
Availability and Penetration• 2700 Y
facilities
• 57% of U.S. households are located within 3 miles of a YMCA
DPP Lifestyle Intervention Delivered in the YMCA
Group randomized pilot comparative effectiveness trial Participants (N = 94)
Overweight/obese High random capillary glucose + T2DM risk factors* Allocated based on YMCA site for screening
Intervention – Offered group-based DPP Control – Given basic advice & other Y programs
Can the YMCA deliver group-based DPP? Could it achieve similar weight loss to DPP? Would it be less costly?

WHERE DID THIS WORK GO?
The National YMCA DPP
Decision to ramp up DEPLOY to YMCAs across the country Standardize training Standardize program elements and adapt
to Y culture.
The National Diabetes Prevention Program
2011: Congressional legislation established the CDC-led National Diabetes Prevention Program
Establish local evidence-based lifestyle change programs for people at high risk for type 2 diabetes Train workforce to implement cost effectively Recognition Program: Assure quality and (hopefully) lead
to reimbursement Develop intervention sites Marketing to support program uptake
Inaugural partners (YMCA and United Health Group)
Already provided services to thousands of patients
Getting it covered as a Benefit: The United Health Group Project
Collaboration between the YMCA and UHG First payer to cover the benefit for persons
identified as high risk by providers and referred to YDPP sites
Scaled payment based on performance
THE YDPP AND THE NDPP ARE GOOD STARTS, BUT STILL FALL FAR SHORT OF THE
SCALE WE NEED TO COMBAT THIS EPIDEMIC.
WHERE CAN WE GO NEXT? HOW CAN WE EXPAND REACH AND ACCESS?
CAN A COMMERCIAL PROGRAM PROVIDE AN ALTERNATIVE APPROACH?

The Study RCT with 250 subjects with diagnosed IGT
Wait list control Comparison of WW with the same self help
program used in DEPLOY Data collected at 6, 12, and 24 months At 6 months, 5.7% weight loss vs. 1% in
controls. At 12 months, 5.8% vs. 2%
The Public Health Promise Weight Watchers is the only at-scale provider of education
behavior modification for weight management in the world, and the only potential DPP partner with
Brand awareness, channel access and investment to drive demand for Diabetes Prevention Programs
Infrastructure to fulfill demand at scale quickly Experience with recruitment, training and
management to deliver consistent, high quality results A built-in base of role model service providers A science-based approach that mirrors that of the DPP

The Encourage Study: targeting kids Introduction of “primordial” prevention Targeting mothers with GDM and their
children Two group RCT:
Moms only Moms plus kids in parallel programs
