In the United States, the incidence of type 2 diabetes mellitus (DM) in children and adolescents has been increasing at an alarming rate. Early recognition and intervention can delay the onset of type 2 DM and prevent the long-term complications. School nurses have an essential role in implementing the American Diabetes Association (ADA) recommended screening guidelines to identify youth at high risk for type 2 DM and in implementing student health programs that focus positively on the importance of physical activity and healthy eating habits. The purpose of this article is to present an overview of the epidemiology, pathophysiology, complications, diagnosis, and treatment, as well as the recommended screening guidelines for type 2 DM in the pediatric age group. The information provided will enhance awareness, promote screening, and empower the school nurse to more effectively promote healthy lifestyle education. (Contains 4 tables and 1 figure.)
