The same factors that increase the risk of developing type 2 diabetes increase the risk of prediabetes, including:

• Extra weight. Being overweight is the main risk factor for prediabetes.
• Inactivity. The less active you are, the greater your risk of prediabetes.
• Advancing age. The risk of prediabetes increases as you get older, especially after age 45.
• Family history. The risk of prediabetes increases if a parent or sibling has type 2 diabetes.
• Race. African-Americans, Hispanics, American Indians, Asian-Americans and Pacific Islanders are more likely to develop prediabetes.
• Gestational diabetes. If you had diabetes when you were pregnant, your risk of developing diabetes later in life increases.
