Research studies have found that moderate weight loss and exercise can prevent or delay type 2 diabetes among adults at high-risk of diabetes. Find out more about the risk factors for type 2 diabetes, what it means to have prediabetes, and what you can do to prevent or delay diabetes. See also EAT RIGHT and BE ACTIVE.
CDC initiated the National Diabetes Prevention Program, which helps organizations make a difference in the health of their community.
The Diabetes Prevention Program (DPP), a major federally funded study of 3,234 people at high risk for diabetes, showed that people can delay and possibly prevent the disease by losing a small amount of weight (5 to 7 percent of total body weight) through 30 minutes of physical activity 5 days a week and healthier eating.

Anyone aged 45 years or older should consider getting tested for diabetes, especially if you are overweight. If you are younger than 45, but are overweight and have one or more additional risk factors (see below), you should consider getting tested.
Being overweight or obese.
Having a parent, brother, or sister with diabetes.
Being African American, American Indian, Asian American, Pacific Islander, or Hispanic American/Latino heritage.
Having a prior history of gestational diabetes or birth of at least one baby weighing more than 9 pounds.
Having high blood pressure measuring 140/90 or higher.
Having abnormal cholesterol with HDL ("good") cholesterol is 35 or lower, or triglyceride level is 250 or higher.
Being physically inactive—exercising fewer than three times a week.

Being overweight or obese is a leading risk factor for type 2 diabetes. Being overweight can keep your body from making and using insulin properly, and can also cause high blood pressure. The Diabetes Prevention Program (DPP), a major federally funded study of 3,234 people at high risk for diabetes, showed that moderate diet and exercise of about 30 minutes or more, 5 or more days per week, or of 150 or more minutes per week, resulting in a 5% to 7% weight loss can delay and possibly prevent type 2 diabetes.
People with blood glucose levels that are higher than normal but not yet in the diabetic range have "prediabetes." Doctors sometimes call this condition impaired fasting glucose (IFG) or impaired glucose tolerance (IGT), depending on the test used to diagnose it. Insulin resistance and prediabetes usually have no symptoms. You may have one or both conditions for several years without noticing anything.
If you have prediabetes, you have a higher risk of developing type 2 diabetes. In additon, people with prediabetes also have a higher risk of heart disease.
Progression to diabetes among those with prediabetes is not inevitable. Studies suggest that weight loss and increased physical activity among people with prediabetes prevent or delay diabetes and may return blood glucose levels to normal.

No. Carefully performed scientific studies show that vaccines do not cause diabetes or increase a person’s risk of developing diabetes. In 2002, the Institute of Medicine reviewed the existing studies and released a report concluding that the scientific evidence favors rejection of the theory that immunizations cause diabetes. The only evidence suggesting a relationship between vaccination and diabetes comes from Dr. John B. Classen, who has suggested that certain vaccines if given at birth may decrease the occurrence of diabetes, whereas if initial vaccination is performed after 2 months of age the occurrence of diabetes increases. Dr. Classen's studies have a number of limitations and have not been verified by other researchers.
