Characteristics of American Young Adults With Increased Risk for Type 2 Diabetes

PURPOSE: The purpose of the study was to examine the characteristics of American young adults with increased risk for type 2 diabetes (T2D). METHODS: Participants ages 18 to 29, overweight/obese, and sedentary were recruited from the metro Atlanta area in the United States. Variables included demographics, anthropometric and clinical variables, and physical activity. Of 107 participants, 3 participants had undiagnosed diabetes and 1 participant did not complete the modifiable activity questionnaire. Thus, 103 young adults remained for the final data analysis. RESULTS: Most participants were females and African Americans. About 30% of participants had prediabetes, either impaired fasting glucose, an A1C of 5.7% to 6.4%, or both. Overall, prediabetes young adults were heavier and did less physical activity than Diabetes Prevention Program (DPP) trial participants. In addition, these young adults had a higher prevalence of parental T2D history and lower level of physical activity compared to young adults with normoglycemia. CONCLUSIONS: Physical activity and parent T2D history are key risk factors for identifying young adults with prediabetes. Multilevel strategies are necessary to raise awareness of diabetes risk and to prevent T2D in young adults.
