Johns Hopkins Diabetes Prevention Program

Prediabetes affects 1 out of 3 U.S. adults; of those, 90% don’t even know they have it. The act2 program is designed to prevent or delay the onset of type 2 diabetes.


Prediabetes is your body’s distress signal

15% to 30% of individuals diagnosed with prediabetes will develop type 2 diabetes.

Prediabetes Facts


  • Prediabetes is a serious health condition that exists when your blood sugar levels are higher than normal but not high enough to be diagnosed as type 2 diabetes.
  • More than 84 million U.S. adults—over a third—have prediabetes and 90% don’t know they have it.
  • Prediabetes puts you at increased risk of developing type 2 diabetes, heart disease, and stroke.
  • 15% to 30% of those diagnosed with prediabetes will develop type 2 diabetes.
  • The good news is that if you have prediabetes, act2 can help you make lifestyle changes to prevent or delay the onset of type 2 diabetes and other serious health problems.

Prediabetes Symptoms & Risk Factors

So often, individuals go years without knowing they have prediabetes. That’s why it’s so important to talk to your doctor about getting your blood sugar tested if you have any of the risk factors:

  • You’re overweight 
  • You’re 45 years or older 
  • A parent, brother or sister has type 2 diabetes
  • You are physically active less than 3 times a week
  • For women, you’ve had gestational diabetes (diabetes during pregnancy) or you gave birth to a baby weighing more than 9 pounds
  • You had or have polycystic ovary syndrome

Race and ethnicity are also a factor: African Americans, Hispanic/Latino Americans, American Indians, Pacific Islanders, and some Asian Americans are at higher risk.
