A new Centers for Disease Control and Prevention study published today in JAMA PediatricsĀ reveals that nearly one in five adolescents aged 12-18 years, and one in four young adults aged 19-34 years, are living with prediabetes, a health condition in which blood sugar levels are higher than normal, but not yet high enough to be diagnosed as type 2 diabetes. The condition increases the risk of developing type 2 diabetes, chronic kidney disease, heart disease and stroke.Ā
