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

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

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?
![Page 27: Diabetes Prevention with Dr. David Marrero](https://reader036.vdocument.in/reader036/viewer/2022062310/58ea568c1a28abb8208b525f/html5/thumbnails/27.jpg)
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)

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?

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?
